Cradle of civilization
–
The cradle of civilization is a term referring to locations where, according to current archaeological data, civilization is understood to have emerged. Current thinking is that there was no single cradle, but several civilizations that developed independently, other civilizations arose in Asia among cultures situated along large river valleys, notably the Indus River in the Indian Subcontinent and the Yellow River in China. The extent to which there was significant influence between the early civilizations of the Near East and those of East Asia is disputed, scholars accept that the civilizations of Mesoamerica, mainly in modern Mexico, and Norte Chico in present-day Peru emerged independently from those in Eurasia. The concept cradle of civilization is the subject of much debate, the figurative use of cradle to mean the place or region in which anything is nurtured or sheltered in its earlier stage is traced by the OED to Spenser. Charles Rollins Ancient History has Egypt that served at first as the cradle of the holy nation, the phrase cradle of civilization plays a certain role in national mysticism. It has been used in Eastern as well as Western cultures, for instance, in Hindu nationalism, the terms also appear in esoteric pseudohistory, such as the Urantia Book, claiming the title for the second Eden, or the pseudoarchaeology related to Megalithic Britain. The earliest proto-urban settlements with several thousand inhabitants emerged in the Neolithic, the first cities to house several tens of thousands were Memphis and Uruk, by the 31st century BCE. Historic times are marked apart from times when records of the past begin to be kept for the benefit of future generations. A civilized way of life is linked to conditions coming almost exclusively from intensive agriculture. A traditional theory of the spread of civilization is that it began in the Fertile Crescent, scholars more generally now believe that civilizations arose independently at several locations in both hemispheres. They have observed that sociocultural developments occurred along different timeframes, sedentary and nomadic communities continued to interact considerably, they were not strictly divided among widely different cultural groups. Current scholarship generally identifies six sites where civilization emerged independently, Mesopotamia, the Nile River, the Indus River, the Yellow River, the Central Andes, one of the most notable PPNA settlements is Jericho in the Levant region, thought to be the worlds first town. In Mesopotamia, the convergence of the Tigris and Euphrates rivers produced rich fertile soil, the civilizations that emerged around these rivers are among the earliest known non-nomadic agrarian societies. It is because of this that the fertile crescent region, the period known as the Ubaid period is the earliest known period on the alluvial plain although it is likely earlier periods exist obscured under the alluvium. It was during the Ubaid period that the movement towards urbanization began, eridu is the oldest Sumerian site settled during this period, around 5300 BCE, and the city of Ur also first dates to the end of this period. In the south, the Ubaid period had a long duration from around 6500 to 3800 BCE. Named after the Sumerian city of Uruk, this saw the emergence of urban life in Mesopotamia and, during its later phase. Proto-writing in the dates to around 3500 BCE, with the earliest texts dating to 3300 BCE

Crescent
–
A crescent shape is a symbol or emblem used to represent the lunar phase in the first quarter, or by extension a symbol representing the Moon itself. It is used as the symbol for the Moon. It was also the emblem of Diana-Artemis, and hence represented virginity, in Roman Catholic Marian veneration, it is associated with the Virgin Mary. From its use as roof finial in Ottoman era mosques, it has become associated with Islam. The crescent symbol is used to represent the Moon, not necessarily in a particular lunar phase. When used to represent a waxing or waning lunar phase, crescent or increscent refers to the waxing first quarter, the crescent symbol was long used as a symbol of the Moon in astrology, and by extension of Silver in alchemy. The astrological use of the symbol is attested in early Greek papyri containing horoscopes, in the 2nd-century Bianchinis planisphere, the personification of the Moon is shown with a crescent attached to her headdress. Its ancient association with Ishtar/Astarte and Diana is preserved in the Moon representing the female principle, as such, it belongs to the class of figures known as lune in planar geometry. The tapering towards the points of intersection of the two arcs are known as the horns of the crescent, the word crescent is derived etymologically from the present participle of the Latin verb crescere to grow, technically denoting the waxing moon. Unicode encodes a crescent at U+263D and a decrescent at U+263E, the Miscellaneous Symbols and Pictographs block provides variants with faces, FIRST QUARTER MOON WITH FACE at U+1F31B and LAST QUARTER MOON WITH FACE at U+1F31C. The crescent shape is used to represent the Moon, and the Moon deity Nanna/Sin from an early time, visible in Akkadian cylinder seals as early as 2300 BC. The crescent was used in the iconography of the Ancient Near East and was used transplanted by the Phoenicians in the 8th century BC as far as Carthage in modern Tunisia. The crescent and star also appears on coins of South Arabia. The combination of star and crescent also arises in the Ancient Near East, representing the Moon and Ishtar and it was inherited both in Sassanian and Hellenistic iconography. In the iconography of the Hellenistic period, the crescent became the symbol of Artemis-Diana, numerous depictions show Artemis-Diana wearing the crescent Moon as part of her headdress. The related symbol of the star and crescent was the emblem of the Mithradates dynasty in the Kingdom of Pontus and was used as the emblem of Byzantium. The crescent remained in use as an emblem in Sassanid Persia, in the Crusades it came to be associated with the Orient and was widely used in Crusader seals and coins. It was used as a charge by the later 13th century

History of agriculture
–
The history of agriculture records the domestication of plants and animals and the development and dissemination of techniques for raising them productively. Agriculture began independently in different parts of the globe, and included a range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin, Wild grains were collected and eaten from at least 20,000 BC. From around 9,500 BC, the eight Neolithic founder crops, emmer and einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Rice was domesticated in China between 11,500 and 6,200 BC, followed by mung, soy and azuki beans, pigs were domesticated in Mesopotamia around 13,000 BC, followed by sheep between 11,000 and 9,000 BC. Cattle were domesticated from the aurochs in the areas of modern Turkey. Sugarcane and some vegetables were domesticated in New Guinea around 7,000 BC. Sorghum was domesticated in the Sahel region of Africa by 5,000 BC, in the Andes of South America, the potato was domesticated between 8,000 and 5,000 BC, along with beans, coca, llamas, alpacas, and guinea pigs. Bananas were cultivated and hybridized in the period in Papua New Guinea. In Mesoamerica, wild teosinte was domesticated to maize by 4,000 BC, cotton was domesticated in Peru by 3,600 BC. Camels were domesticated late, perhaps around 3,000 BC, irrigation, crop rotation, and fertilizers were introduced soon after the Neolithic Revolution and developed much further in the past 200 years, starting with the British Agricultural Revolution. The Haber-Bosch process allowed the synthesis of nitrate fertilizer on an industrial scale. Modern agriculture has raised social, political, and environmental issues including pollution, biofuels, genetically modified organisms, tariffs. In response, organic farming developed in the century as a consciously pesticide-free alternative. Scholars have developed a number of hypotheses to explain the origins of agriculture. Current models indicate that wild stands that had been harvested previously started to be planted, localised climate change is the favoured explanation for the origins of agriculture in the Levant. When major climate change took place after the last ice age and these conditions favoured annual plants which die off in the long dry season, leaving a dormant seed or tuber. An abundance of readily storable wild grains and pulses enabled hunter-gatherers in some areas to form the first settled villages at this time, early people began altering communities of flora and fauna for their own benefit through means such as fire-stick farming and forest gardening very early

Civilization
–
Historically, a civilization was a so-called advanced culture in contrast to more supposedly primitive cultures. As an uncountable noun, civilization also refers to the process of a society developing into a centralized, urbanized, stratified structure, Civilization concentrates power, extending human control over the rest of nature, including over other human beings. The earlier neolithic technology and lifestyle was established first in the Middle East, and later in the Yangtze and Yellow River basins in China, similar pre-civilized neolithic revolutions also began independently from 7,000 BCE in such places as northwestern South America and Mesoamerica. These were among the six civilizations worldwide that arose independently, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BCE, with civilizations developing from 6,500 years ago. Towards the end of the Neolithic period, various elitist Chalcolithic civilizations began to rise in various cradles from around 3300 BCE. Chalcolithic civilizations, as defined above, also developed in Pre-Columbian Americas and, despite an early start in Egypt, Axum and Kush, the English word civilization comes from the 16th-century French civilisé, from Latin civilis, related to civis and civitas. The fundamental treatise is Norbert Eliass The Civilizing Process, which traces social mores from medieval courtly society to the Early Modern period, in The Philosophy of Civilization, Albert Schweitzer outlines two opinions, one purely material and the other material and ethical. Adjectives like civility developed in the mid-16th century, the abstract noun civilization, meaning civilized condition, came in the 1760s, again from French. The word was therefore opposed to barbarism or rudeness, in the pursuit of progress characteristic of the Age of Enlightenment. In the late 1700s and early 1800s, during the French revolution, civilization was used in the singular, never in the plural and this is still the case in French. The use of civilizations as a noun was in occasional use in the 19th century. Only in this sense does it become possible to speak of a medieval civilization. Already in the 18th century, civilization was not always seen as an improvement, one historically important distinction between culture and civilization is from the writings of Rousseau, particularly his work about education, Emile. From this, a new approach was developed, especially in Germany, first by Johann Gottfried Herder and this sees cultures as natural organisms, not defined by conscious, rational, deliberative acts, but a kind of pre-rational folk spirit. Civilization, in contrast, though more rational and more successful in material progress, is unnatural and leads to vices of social life such as guile, hypocrisy, envy and avarice. In World War II, Leo Strauss, having fled Germany, argued in New York that this opinion of civilization was behind Nazism, Social scientists such as V. Gordon Childe have named a number of traits that distinguish a civilization from other kinds of society. Andrew Nikiforuk argues that civilizations relied on shackled human muscle and it took the energy of slaves to plant crops, clothe emperors, and build cities and considers slavery to be a common feature of pre-modern civilizations. All civilizations have depended on agriculture for subsistence, grain farms can result in accumulated storage and a surplus of food, particularly when people use intensive agricultural techniques such as artificial fertilization, irrigation and crop rotation

Sumer
–
Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Proto-writing in the dates back to c.3000 BC. The earliest texts come from the cities of Uruk and Jemdet Nasr and date back to 3300 BC, modern historians have suggested that Sumer was first permanently settled between c.5500 and 4000 BC by a West Asian people who spoke the Sumerian language, an agglutinative language isolate. These conjectured, prehistoric people are now called proto-Euphrateans or Ubaidians, some scholars contest the idea of a Proto-Euphratean language or one substrate language. Reliable historical records begin much later, there are none in Sumer of any kind that have dated before Enmebaragesi. Juris Zarins believes the Sumerians lived along the coast of Eastern Arabia, todays Persian Gulf region, Sumerian civilization took form in the Uruk period, continuing into the Jemdet Nasr and Early Dynastic periods. During the 3rd millennium BC, a cultural symbiosis developed between the Sumerians, who spoke a language isolate, and Akkadian-speakers, which included widespread bilingualism. The influence of Sumerian on Akkadian is evident in all areas, from lexical borrowing on a scale, to syntactic, morphological. This has prompted scholars to refer to Sumerian and Akkadian in the 3rd millennium BC as a Sprachbund, Sumer was conquered by the Semitic-speaking kings of the Akkadian Empire around 2270 BC, but Sumerian continued as a sacred language. Native Sumerian rule re-emerged for about a century in the Neo-Sumerian Empire or Third Dynasty of Ur approximately 2100-2000 BC, the term Sumerian is the common name given to the ancient non-Semitic-speaking inhabitants of Mesopotamia, Sumer, by the East Semitic-speaking Akkadians. The Sumerians referred to themselves as ùĝ saĝ gíg ga, phonetically /uŋ saŋ gi ga/, literally meaning the black-headed people, the Akkadian word Shumer may represent the geographical name in dialect, but the phonological development leading to the Akkadian term šumerû is uncertain. Hebrew Shinar, Egyptian Sngr, and Hittite Šanhar, all referring to southern Mesopotamia, in the late 4th millennium BC, Sumer was divided into many independent city-states, which were divided by canals and boundary stones. Each was centered on a dedicated to the particular patron god or goddess of the city. The Sumerian city-states rose to power during the prehistoric Ubaid and Uruk periods, classical Sumer ends with the rise of the Akkadian Empire in the 23rd century BC. Following the Gutian period, there is a brief Sumerian Renaissance in the 21st century BC, the Amorite dynasty of Isin persisted until c.1700 BC, when Mesopotamia was united under Babylonian rule. The Sumerians were eventually absorbed into the Akkadian population, 2500–2334 BC Akkadian Empire period, c. 2218–2047 BC Ur III period, c, 2047–1940 BC The Ubaid period is marked by a distinctive style of fine quality painted pottery which spread throughout Mesopotamia and the Persian Gulf. It appears that this culture was derived from the Samarran culture from northern Mesopotamia and it is not known whether or not these were the actual Sumerians who are identified with the later Uruk culture

Ancient Egypt
–
Ancient Egypt was a civilization of ancient Northeastern Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. It is one of six civilizations to arise independently, Egyptian civilization followed prehistoric Egypt and coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh Narmer. In the aftermath of Alexander the Greats death, one of his generals, Ptolemy Soter and this Greek Ptolemaic Kingdom ruled Egypt until 30 BC, when, under Cleopatra, it fell to the Roman Empire and became a Roman province. The success of ancient Egyptian civilization came partly from its ability to adapt to the conditions of the Nile River valley for agriculture, the predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world and its monumental ruins have inspired the imaginations of travelers and writers for centuries. The Nile has been the lifeline of its region for much of human history, nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the climate of Northern Africa became increasingly hot and dry. In Predynastic and Early Dynastic times, the Egyptian climate was less arid than it is today. Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates, foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated. The largest of these cultures in upper Egypt was the Badari, which probably originated in the Western Desert, it was known for its high quality ceramics, stone tools. The Badari was followed by the Amratian and Gerzeh cultures, which brought a number of technological improvements, as early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes. In Naqada II times, early evidence exists of contact with the Near East, particularly Canaan, establishing a power center at Hierakonpolis, and later at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile. They also traded with Nubia to the south, the oases of the desert to the west. Royal Nubian burials at Qustul produced artifacts bearing the oldest-known examples of Egyptian dynastic symbols, such as the crown of Egypt. They also developed a ceramic glaze known as faience, which was used well into the Roman Period to decorate cups, amulets, and figurines. During the last predynastic phase, the Naqada culture began using written symbols that eventually were developed into a system of hieroglyphs for writing the ancient Egyptian language. The Early Dynastic Period was approximately contemporary to the early Sumerian-Akkadian civilisation of Mesopotamia, the third-century BC Egyptian priest Manetho grouped the long line of pharaohs from Menes to his own time into 30 dynasties, a system still used today

Nile
–
The Nile is a major north-flowing river in northeastern Africa. It is generally regarded as the longest river in the world, in particular, the Nile is the primary water source of Egypt and Sudan. The Nile has two tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself, the Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa and it flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast, the two rivers meet just north of the Sudanese capital of Khartoum. The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta, Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, in the ancient Egyptian language, the Nile is called Ḥpī or Iteru, meaning river. In Coptic, the words piaro or phiaro meaning the river come from the ancient name. The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the Latin Nilus and the Ancient Greek Νεῖλος, beyond that, however, the etymology is disputed. One possible etymology derives it from a Semitic Nahal, meaning river, the standard English names White Nile and Blue Nile, to refer to the rivers source, derive from Arabic names formerly applied only to the Sudanese stretches which meet at Khartoum. Above Khartoum, the Nile is also known as the White Nile, at Khartoum the river is joined by the Blue Nile. The White Nile starts in equatorial East Africa, and the Blue Nile begins in Ethiopia, both branches are on the western flanks of the East African Rift. The drainage basin of the Nile covers 3,254,555 square kilometers, the source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. It is either the Ruvyironza, which emerges in Bururi Province, Burundi, or the Nyabarongo, the two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border. Gish Abay is reportedly the place where the water of the first drops of the Blue Nile develop. The Nile leaves Lake Nyanza at Ripon Falls near Jinja, Uganda and it flows north for some 130 kilometers, to Lake Kyoga. For the remaining part it flows westerly through the Murchison Falls until it reaches the very northern shores of Lake Albert where it forms a significant river delta
8.
Euphrates
–
The Euphrates is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia, originating in eastern Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf. The Ancient Greek form Euphrátēs was borrowed from Old Persian Ufrātu, the Elamite name is ultimately derived from the Sumerian Buranuna, possibly through the Akkadian name. In Akkadian the river was similarly called Purattu, which has been perpetuated in Semitic languages, the Elamite, Akkadian, and possibly Sumerian forms are suggested to be from an unrecorded substrate language. The earliest references to the Euphrates come from texts found in Shuruppak and pre-Sargonic Nippur in southern Iraq. In these texts, written in Sumerian, the Euphrates is called Buranuna, the name could also be written KIB. NUN. or dKIB. NUN, with the prefix d indicating that the river was a divinity. In Sumerian, the name of the city of Sippar in modern-day Iraq was also a written UD. KIB. NUN, the Euphrates is the longest river of Western Asia. It emerges from the confluence of the Kara Su or Western Euphrates, the same figures are given by Isaev and Mikhailova. The length of the Shatt al-Arab, which connects the Euphrates, both the Kara Su and the Murat Su rise northwest from Lake Van at elevations of 3,290 metres and 3,520 metres amsl, respectively. At the location of the Keban Dam, the two rivers, now combined into the Euphrates, have dropped to an elevation of 693 metres amsl, from Keban to the Syrian–Turkish border, the river drops another 368 metres over a distance of less than 600 kilometres. The Euphrates receives most of its water in the form of rainfall and melting snow, discharge in these two months accounts for 36 percent of the total annual discharge of the Euphrates, or even 60–70 percent according to one source, while low runoff occurs in summer and autumn. The discharge regime of the Euphrates has changed dramatically since the construction of the first dams in the 1970s, data on Euphrates discharge collected after 1990 show the impact of the construction of the numerous dams in the Euphrates and of the increased withdrawal of water for irrigation. Average discharge at Hīt after 1990 has dropped to 356 cubic metres per second, the seasonal variability has equally changed. The pre-1990 peak volume recorded at Hīt was 7,510 cubic metres per second, the minimum volume at Hīt remained relatively unchanged, rising from 55 cubic metres per second before 1990 to 58 cubic metres per second afterward. In Syria, three rivers add their water to the Euphrates, the Sajur, the Balikh and the Khabur and these rivers rise in the foothills of the Taurus Mountains along the Syro–Turkish border and add comparatively little water to the Euphrates. The Sajur is the smallest of these tributaries, emerging from two streams near Gaziantep and draining the plain around Manbij before emptying into the reservoir of the Tishrin Dam. The Balikh receives most of its water from a spring near Ayn al-Arus. In terms of length, drainage basin and discharge, the Khabur is the largest of these three and its main karstic springs are located around Ras al-Ayn, from where the Khabur flows southeast past Al-Hasakah, where the river turns south and drains into the Euphrates near Busayrah

Tigris
–
The Tigris is the eastern member of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of southeastern Turkey through Iraq, the Tigris is 1,850 km long, rising in the Taurus Mountains of eastern Turkey about 25 km southeast of the city of Elazig and about 30 km from the headwaters of the Euphrates. The river then flows for 400 km through Turkish territory before becoming the border between Syria and Turkey and this stretch of 44 km is the only part of the river that is located in Syria. Close to its confluence with the Euphrates, the Tigris splits into several channels, First, the artificial Shatt al-Hayy branches off, to join the Euphrates near Nasiriyah. Second, the Shatt al-Muminah and Majar-al-Kabir branch off to feed the Central Marshes, further downstream, two other distributary channels branch off, which feed the Hawizeh Marshes. The main channel continues southwards and is joined by the Al-Kassarah, finally, the Tigris joins the Euphrates near al-Qurnah to form the Shatt-al-Arab. According to Pliny and other ancient historians, the Euphrates originally had its outlet into the sea separate from that of the Tigris, Baghdad, the capital of Iraq, stands on the banks of the Tigris. The port city of Basra straddles the Shatt al-Arab, in ancient times, many of the great cities of Mesopotamia stood on or near the Tigris, drawing water from it to irrigate the civilization of the Sumerians. Notable Tigris-side cities included Nineveh, Ctesiphon, and Seleucia, while the city of Lagash was irrigated by the Tigris via a canal dug around 2400 B. C, the Tigris has long been an important transport route in a largely desert country. Shallow-draft vessels can go as far as Baghdad, but rafts are needed for transport upstream to Mosul, General Francis Rawdon Chesney hauled two steamers overland through Syria in 1836 to explore the possibility of an overland and river route to India. One steamer, the Tigris, was wrecked in a storm which sank, Chesney proved the river navigable to powered craft. Later, the Euphrates and Tigris Steam Navigation Company was established in 1861 by the Lynch Brothers trading company and they had 2 steamers in service. By 1908 ten steamers were on the river, tourists boarded steam yachts to venture inland as this was the first age of archaeological tourism, and the sites of Ur and Ctesiphon became popular to European travelers. In the First World War, during the British conquest of Ottoman Mesopotamia, Indian, see Siege of Kut and the Fall of Baghdad. The Tigris Flotilla included vessels Clio, Espiegle, Lawrence, Odin, armed tug Comet, armed launches Lewis Pelly, Miner, Shaitan, Sumana, and stern wheelers Muzaffari/Mozaffir. These were joined by Royal Navy Fly-class gunboats Butterfly, Cranefly, Dragonfly, Mayfly, Sawfly, Snakefly, and Mantis, Moth, the Ancient Greek form Tigris was borrowed from Old Persian Tigrā, itself from Elamite Tigra, itself from Sumerian Idigna. The Sumerian form was borrowed into Akkadian as Idiqlat, and from there into the other Semitic languages, another name for the Tigris used in Middle Persian was Arvand Rud, literally swift river. Today, however, Arvand Rud refers to the confluence of the Euphrates, in Kurdish, it is also known as Ava Mezin, the Great Water

History of writing
–
The history of writing traces the development of expressing language by letters or other marks and also the study and description of these developments. One of the earliest forms of expression is cuneiform. Writing numbers for the purpose of record keeping began long before the writing of language, see History of writing ancient numbers for how the writing of numbers began. It is generally agreed that true writing of language was conceived and developed in at least two places and possibly more. Egyptian script is dissimilar from Mesopotamian cuneiform, but similarities in concepts, similar debate surrounds the Indus script of the Bronze Age Indus Valley civilization in Ancient India. In addition, the script is still undeciphered and there is debate whether the script is true writing at all. An additional possibility is the undeciphered Rongorongo script of Easter Island and it is debated whether this is true writing, and if it is, whether it is another case of cultural diffusion of writing. The oldest example is from 1851,139 years after their first contact with Europeans, one explanation is that the script was inspired by Spains written annexation proclamation in 1770. Recent examples are the Cherokee syllabary, invented by Sequoyah, symbolic communication systems are distinguished from writing systems in that one must usually understand something of the associated spoken language to comprehend the text. In contrast, symbolic systems such as signs, painting, maps. Every human community possesses language, a feature regarded by many as an innate, however the development of writing systems, and their partial supplantation of traditional oral systems of communication, have been sporadic, uneven and slow. Once established, writing systems on the change more slowly than their spoken counterparts. Writing allows societies to transmit information and share knowledge, scholars make a reasonable distinction between prehistory and history of early writing, but have disagreed concerning when prehistory becomes history and when proto-writing became true writing. Writing, in its most general terms, is a method of recording information and is composed of graphemes, the emergence of writing in a given area is usually followed by several centuries of fragmentary inscriptions. Historians mark the historicity of a culture by the presence of coherent texts in the writing system. The invention of writing was not an event, but a gradual process initiated by the appearance of symbols. A conventional proto-writing to true writing system follows a series of developmental stages, Picture writing system. Transitional system, graphemes refer not only to the object or idea which it represents, phonetic system, graphemes refer to sounds or spoken symbols, and the form of the grapheme is not related to its meanings

Glass
–
Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. The most familiar, and historically the oldest, types of glass are silicate glasses based on the chemical compound silica, the primary constituent of sand. The term glass, in usage, is often used to refer only to this type of material. Many applications of silicate glasses derive from their optical transparency, giving rise to their use as window panes. Glass can be coloured by adding metallic salts, and can also be painted and printed with vitreous enamels and these qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures, because glass can be formed or moulded into any shape, it has been traditionally used for vessels, bowls, vases, bottles, jars and drinking glasses. In its most solid forms it has also used for paperweights, marbles. Some objects historically were so commonly made of glass that they are simply called by the name of the material, such as drinking glasses. Porcelains and many polymer thermoplastics familiar from everyday use are glasses and these sorts of glasses can be made of quite different kinds of materials than silica, metallic alloys, ionic melts, aqueous solutions, molecular liquids, and polymers. For many applications, like glass bottles or eyewear, polymer glasses are a lighter alternative than traditional glass, silica is a common fundamental constituent of glass. In nature, vitrification of quartz occurs when lightning strikes sand, forming hollow, fused quartz is a glass made from chemically-pure SiO2. It has excellent resistance to shock, being able to survive immersion in water while red hot. However, its high melting-temperature and viscosity make it difficult to work with, normally, other substances are added to simplify processing. One is sodium carbonate, which lowers the transition temperature. The soda makes the glass water-soluble, which is undesirable, so lime, some magnesium oxide. The resulting glass contains about 70 to 74% silica by weight and is called a soda-lime glass, soda-lime glasses account for about 90% of manufactured glass. Most common glass contains other ingredients to change its properties, lead glass or flint glass is more brilliant because the increased refractive index causes noticeably more specular reflection and increased optical dispersion. Adding barium also increases the refractive index, iron can be incorporated into glass to absorb infrared energy, for example in heat absorbing filters for movie projectors, while cerium oxide can be used for glass that absorbs UV wavelengths
12.
Wheel
–
A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the components of the wheel. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, wheels are also used for other purposes, such as a ships wheel, steering wheel, potters wheel and flywheel. Common examples are found in transport applications, a wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, cognates within Indo-European include Icelandic hjól wheel, tyre, Greek κύκλος kúklos, and Sanskrit chakra, the latter both meaning circle or wheel. The invention of the falls into the late Neolithic. Note that this implies the passage of several wheel-less millennia even after the invention of agriculture and of pottery, precursors of wheels, known as tournettes or slow wheels, were known in the Middle East by the 5th millennium BCE. These were made of stone or clay and secured to the ground with a peg in the center, but required effort to turn. True potters wheels were apparently in use in Mesopotamia by 3500 BCE and possibly as early as 4000 BCE, and the oldest surviving example, which was found in Ur, dates to approximately 3100 BCE. The earliest well-dated depiction of a vehicle is on the Bronocice pot. The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia is now dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE. Two types of early Neolithic European wheel and axle are known, a type of wagon construction. They both are dated to c, in China, the wheel was certainly present with the adoption of the chariot in c.1200 BCE, although Barbieri-Low argues for earlier Chinese wheeled vehicles, c.2000 BC. In Britain, a wooden wheel, measuring about 1 m in diameter, was uncovered at the Must Farm site in East Anglia in 2016. The specimen, dating from 1, 100–800 years BCE, represents the most complete, the wheels hub is also present. A horses spine found nearby suggests the wheel may have part of a horse-drawn cart. The wheel was found in a settlement built on stilts over wetland and it is thought that the primary obstacle to large-scale development of the wheel in the Americas was the absence of domesticated large animals which could be used to pull wheeled carriages. The only large animal that was domesticated in the Western hemisphere, Nubians from after about 400 BCE used wheels for spinning pottery and as water wheels

Agriculture
–
Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life. Agriculture was the key development in the rise of human civilization. The study of agriculture is known as agricultural science, the history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology, genetically modified organisms are an increasing component of agriculture, although they are banned in several countries. Agricultural food production and water management are increasingly becoming global issues that are fostering debate on a number of fronts, the major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. Specific foods include cereals, vegetables, fruits, oils, meats, fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo, other useful materials are also produced by plants, such as resins, dyes, drugs, perfumes, biofuels and ornamental products such as cut flowers and nursery plants. The word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, field, Agriculture usually refers to human activities, although it is also observed in certain species of ant, termite and ambrosia beetle. To practice agriculture means to use resources to produce commodities which maintain life, including food, fiber, forest products, horticultural crops. This definition includes arable farming or agronomy, and horticulture, all terms for the growing of plants, even then, it is acknowledged that there is a large amount of knowledge transfer and overlap between silviculture and agriculture. In traditional farming, the two are often combined even on small landholdings, leading to the term agroforestry, Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin, wild grains were collected and eaten from at least 105,000 years ago. Pigs were domesticated in Mesopotamia around 15,000 years ago, rice was domesticated in China between 13,500 and 8,200 years ago, followed by mung, soy and azuki beans. Sheep were domesticated in Mesopotamia between 13,000 and 11,000 years ago. From around 11,500 years ago, the eight Neolithic founder crops, emmer and einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Cattle were domesticated from the aurochs in the areas of modern Turkey. In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, coca, llamas, alpacas, sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago, cotton was domesticated in Peru by 5,600 years ago, and was independently domesticated in Eurasia at an unknown time

Irrigation
–
Irrigation is the method in which a controlled amount of water is supplied to plants at regular intervals for agriculture. It is used to assist in the growing of crops, maintenance of landscapes. Additionally, irrigation also has a few uses in crop production. In contrast, agriculture that only on direct rainfall is referred to as rain-fed or dry land farming. Irrigation systems are used for dust suppression, disposal of sewage. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area, Irrigation has been a central feature of agriculture for over 5,000 years and is the product of many cultures. Historically, it was the basis for economies and societies across the globe, archaeological investigation has found evidence of irrigation where the natural rainfall was insufficient to support crops for rainfed agriculture. Ancient Egyptians practiced Basin irrigation using the flooding of the Nile to inundate land plots which had surrounded by dykes. The flood water was held until the sediment had settled before the surplus was returned to the watercourse. The Ancient Nubians developed a form of irrigation by using a device called a sakia. Irrigation began in Nubia some time between the third and second millennium BCE and it largely depended upon the flood waters that would flow through the Nile River and other rivers in what is now the Sudan. In sub-Saharan Africa irrigation reached the Niger River region cultures and civilizations by the first or second millennium BCE and was based on wet season flooding, terrace irrigation is evidenced in pre-Columbian America, early Syria, India, and China. These canals are the earliest record of irrigation in the New World, traces of a canal possibly dating from the 5th millennium BCE were found under the 4th millennium canal. Large scale agriculture was practiced and a network of canals was used for the purpose of irrigation. Ancient Persia as far back as the 6th millennium BCE, where barley was grown in areas where the rainfall was insufficient to support such a crop. The Qanats, developed in ancient Persia in about 800 BCE, are among the oldest known irrigation methods still in use today and they are now found in Asia, the Middle East and North Africa. The system comprises a network of wells and gently sloping tunnels driven into the sides of cliffs. The noria, a wheel with clay pots around the rim powered by the flow of the stream, was first brought into use at about this time

Iraq
–
The capital, and largest city, is Baghdad. The main ethnic groups are Arabs and Kurds, others include Assyrians, Turkmen, Shabakis, Yazidis, Armenians, Mandeans, Circassians, around 95% of the countrys 36 million citizens are Muslims, with Christianity, Yarsan, Yezidism, and Mandeanism also present. The official languages of Iraq are Arabic and Kurdish, two major rivers, the Tigris and Euphrates, run south through Iraq and into the Shatt al-Arab near the Persian Gulf. These rivers provide Iraq with significant amounts of fertile land, the region between the Tigris and Euphrates rivers, historically known as Mesopotamia, is often referred to as the cradle of civilisation. It was here that mankind first began to read, write, create laws, the area has been home to successive civilisations since the 6th millennium BC. Iraq was the centre of the Akkadian, Sumerian, Assyrian and it was also part of the Median, Achaemenid, Hellenistic, Parthian, Sassanid, Roman, Rashidun, Umayyad, Abbasid, Ayyubid, Mongol, Safavid, Afsharid, and Ottoman empires. Iraqs modern borders were mostly demarcated in 1920 by the League of Nations when the Ottoman Empire was divided by the Treaty of Sèvres, Iraq was placed under the authority of the United Kingdom as the British Mandate of Mesopotamia. A monarchy was established in 1921 and the Kingdom of Iraq gained independence from Britain in 1932, in 1958, the monarchy was overthrown and the Iraqi Republic created. Iraq was controlled by the Arab Socialist Baath Party from 1968 until 2003, after an invasion by the United States and its allies in 2003, Saddam Husseins Baath Party was removed from power and multi-party parliamentary elections were held in 2005. The American presence in Iraq ended in 2011, but the Iraqi insurgency continued and intensified as fighters from the Syrian Civil War spilled into the country, the Arabic name العراق al-ʿIrāq has been in use since before the 6th century. There are several suggested origins for the name, one dates to the Sumerian city of Uruk and is thus ultimately of Sumerian origin, as Uruk was the Akkadian name for the Sumerian city of Urug, containing the Sumerian word for city, UR. An Arabic folk etymology for the name is rooted, well-watered. During the medieval period, there was a region called ʿIrāq ʿArabī for Lower Mesopotamia and ʿIrāq ʿajamī, for the region now situated in Central and Western Iran. The term historically included the south of the Hamrin Mountains. The term Sawad was also used in early Islamic times for the region of the plain of the Tigris and Euphrates rivers. In English, it is either /ɪˈrɑːk/ or /ɪˈræk/, the American Heritage Dictionary, the pronunciation /aɪˈræk/ is frequently heard in U. S. media. Since approximately 10,000 BC, Iraq was one of centres of a Caucasoid Neolithic culture where agriculture, the following Neolithic period is represented by rectangular houses. At the time of the pre-pottery Neolithic, people used vessels made of stone, gypsum, finds of obsidian tools from Anatolia are evidences of early trade relations

Syria
–
Syrias capital and largest city is Damascus. Religious groups include Sunnis, Christians, Alawites, Druze, Mandeans, Shiites, Salafis, Sunni Arabs make up the largest religious group in Syria. Its capital Damascus and largest city Aleppo are among the oldest continuously inhabited cities in the world, in the Islamic era, Damascus was the seat of the Umayyad Caliphate and a provincial capital of the Mamluk Sultanate in Egypt. The post-independence period was tumultuous, and a number of military coups. In 1958, Syria entered a union with Egypt called the United Arab Republic. Syria was under Emergency Law from 1963 to 2011, effectively suspending most constitutional protections for citizens, Bashar al-Assad has been president since 2000 and was preceded by his father Hafez al-Assad, who was in office from 1970 to 2000. Mainstream modern academic opinion strongly favours the argument that the Greek word is related to the cognate Ἀσσυρία, Assyria, in the past, others believed that it was derived from Siryon, the name that the Sidonians gave to Mount Hermon. However, the discovery of the inscription in 2000 seems to support the theory that the term Syria derives from Assyria. The area designated by the word has changed over time, since approximately 10,000 BC, Syria was one of centers of Neolithic culture where agriculture and cattle breeding appeared for the first time in the world. The following Neolithic period is represented by houses of Mureybet culture. At the time of the pre-pottery Neolithic, people used vessels made of stone, gyps, finds of obsidian tools from Anatolia are evidences of early trade relations. Cities of Hamoukar and Emar played an important role during the late Neolithic, archaeologists have demonstrated that civilization in Syria was one of the most ancient on earth, perhaps preceded by only those of Mesopotamia. The earliest recorded indigenous civilisation in the region was the Kingdom of Ebla near present-day Idlib, gifts from Pharaohs, found during excavations, confirm Eblas contact with Egypt. One of the earliest written texts from Syria is an agreement between Vizier Ibrium of Ebla and an ambiguous kingdom called Abarsal c.2300 BC. The Northwest Semitic language of the Amorites is the earliest attested of the Canaanite languages, Mari reemerged during this period, and saw renewed prosperity until conquered by Hammurabi of Babylon. Ugarit also arose during this time, circa 1800 BC, close to modern Latakia, Ugaritic was a Semitic language loosely related to the Canaanite languages, and developed the Ugaritic alphabet. The Ugarites kingdom survived until its destruction at the hands of the marauding Indo-European Sea Peoples in the 12th century BC, Yamhad was described in the tablets of Mari as the mightiest state in the near east and as having more vassals than Hammurabi of Babylon. Yamhad imposed its authority over Alalakh, Qatna, the Hurrians states, the army of Yamhad campaigned as far away as Dēr on the border of Elam

Lebanon, officially known as the Lebanese Republic, is a sovereign state in Western Asia. It is bordered by Syria to the north and east and Israel to the south, Lebanons location at the crossroads of the Mediterranean Basin and the Arabian hinterland facilitated its rich history and shaped a cultural identity of religious and ethnic diversity. At just 10,452 km2, it is the smallest recognized country on the entire mainland Asian continent, the earliest evidence of civilization in Lebanon dates back more than seven thousand years, predating recorded history. Lebanon was the home of the Canaanites/Phoenicians and their kingdoms, a culture that flourished for over a thousand years. In 64 BC, the region came under the rule of the Roman Empire, in the Mount Lebanon range a monastic tradition known as the Maronite Church was established. As the Arab Muslims conquered the region, the Maronites held onto their religion, however, a new religious group, the Druze, established themselves in Mount Lebanon as well, generating a religious divide that has lasted for centuries. During the Crusades, the Maronites re-established contact with the Roman Catholic Church, the ties they established with the Latins have influenced the region into the modern era. The region eventually was ruled by the Ottoman Empire from 1516 to 1918, following the collapse of the empire after World War I, the five provinces that constitute modern Lebanon came under the French Mandate of Lebanon. The French expanded the borders of the Mount Lebanon Governorate, which was populated by Maronites and Druze. Lebanon gained independence in 1943, establishing confessionalism, a unique, foreign troops withdrew completely from Lebanon on 31 December 1946. Lebanon has been a member of the Organisation internationale de la francophonie since 1973, despite its small size, the country has developed a well-known culture and has been highly influential in the Arab world. Before the Lebanese Civil War, the experienced a period of relative calm and renowned prosperity, driven by tourism, agriculture, commerce. At the end of the war, there were efforts to revive the economy. In spite of troubles, Lebanon has the highest Human Development Index and GDP per capita in the Arab world. The name of Mount Lebanon originates from the Phoenician root lbn meaning white, occurrences of the name have been found in different Middle Bronze Age texts from the library of Ebla, and three of the twelve tablets of the Epic of Gilgamesh. The name is recorded in Ancient Egyptian as Rmnn, where R stood for Canaanite L, the name occurs nearly 70 times in the Hebrew Bible, as לְבָנוֹן. The borders of contemporary Lebanon are a product of the Treaty of Sèvres of 1920 and its territory was the core of the Bronze Age Phoenician city-states.

Cyprus, officially the Republic of Cyprus, is an island country in the Eastern Mediterranean and the third largest and third most populous island in the Mediterranean. It is located south of Turkey, west of Syria and Lebanon, northwest of Israel and Palestine, north of Egypt, the earliest known human activity on the island dates to around the 10th millennium BC. Archaeological remains from this include the well-preserved Neolithic village of Khirokitia. Cyprus was settled by Mycenaean Greeks in two waves in the 2nd millennium BC, Cyprus was placed under British administration based on Cyprus Convention in 1878 and formally annexed by Britain in 1914. While Turkish Cypriots made up 18% of the population, the partition of Cyprus and creation of a Turkish state in the north became a policy of Turkish Cypriot leaders, following nationalist violence in the 1950s, Cyprus was granted independence in 1960. On 15 July 1974, a coup détat was staged by Greek Cypriot nationalists and elements of the Greek military junta in an attempt at enosis and these events and the resulting political situation are matters of a continuing dispute. The Cyprus Republic has de jure sovereignty over the island of Cyprus, as well as its territorial sea and exclusive economic area, another nearly 4% of the islands area is covered by the UN buffer zone. The international community considers the part of the island as territory of the Republic of Cyprus occupied by Turkish forces. The occupation is viewed as illegal under law, amounting to illegal occupation of EU territory since Cyprus became a member of the European Union. Cyprus is a major tourist destination in the Mediterranean, on 1 January 2008, the Republic of Cyprus joined the eurozone. The earliest attested reference to Cyprus is the 15th century BC Mycenaean Greek

Jordan is bordered by Saudi Arabia to the east and south, Iraq to the north-east, Syria to the north, Israel, Palestine and the Dead Sea to the west, Jordan is strategically located at the crossroads of Asia, Africa and Europe. The capital, Amman, is Jordans most populous city as well as the countrys economic, what is now Jordan has been inhabited by humans since the Paleolithic period. Three stable kingdoms emerged there at the end of the Bronze Age, Ammon, Moab, later rulers include the Nabataean Kingdom, the Roman Empire, and the Ottoman Empire. After the Great Arab Revolt against the Ottomans in 1916 during World War I, the Emirate of Transjordan was established in 1921 by the then Emir Abdullah I and became a British protectorate.

It coexists with an indigenous Christian minority, Jordan is considered to be among the safest of Arab countries in the Middle East, and has avoided long-term terrorism and instability. The kingdom is also a refuge to thousands of Iraqi Christians fleeing the Islamic State, while Jordan continues to accept refugees, the recent large influx from Syria placed substantial strain on national resources and infrastructure. Jordan is classified as a country of high human development with a middle income economy. The Jordanian economy, one of the smallest economies in the region, is attractive to foreign investors based upon a skilled workforce, the country is a major tourist destination, and also attracts medical tourism due to its well developed health sector. Nonetheless, a lack of resources, large flow of refugees. Jordan is named after the Jordan River, where Jesus is said to have been baptized, the origin of the rivers name is debated, but the most common explanation is that it derives from the word yarad, found in Hebrew, Aramaic, and other Semitic languages. Others regard the name as having an Indo-Aryan origin, combining the words yor and don, another theory is that it is from the Arabic root word wrd, as in people coming to a major source of water. The name Jordan appears in an ancient Egyptian papyrus called Papyrus Anastasi I, the lands of modern-day Jordan were historically called Transjordan, meaning beyond the Jordan River. The name was Arabized into Al-Urdunn during the Muslim conquest of the Levant, during crusader rule, it was called Oultrejordain

State of Palestine
–
The State of Palestine claims the West Bank and Gaza Strip with East Jerusalem as the designated capital. Most of the areas claimed by the State of Palestine have been occupied by Israel since 1967 in the aftermath of the Six-Day War and its independence was declared on 15 November 1988 by the Palestine Liberation Organization in Algiers as a government-in-exile. Since the British Mandate, the term Palestine has been associated with the area that currently covers the State of Israel, the West Bank. In 1947, the UN adopted a plan for a two-state solution in the remaining territory of the mandate. The plan was accepted by the Jewish leadership but rejected by the Arab leaders, on the eve of final British withdrawal, the Jewish Agency for Israel declared the establishment of the State of Israel according to the proposed UN plan. During the war, Israel gained additional territories that were designated to be part of the Arab state under the UN plan, Egypt occupied the Gaza Strip and Transjordan occupied the West Bank. Egypt initially supported the creation of an All-Palestine Government, but disbanded it in 1959, Transjordan never recognized it and instead decided to incorporate the West Bank with its own territory to form Jordan. The annexation was ratified in 1950 but was rejected by the international community, the Six-Day War in 1967, when Egypt, Jordan, and Syria fought against Israel, ended with Israel being in occupation of the West Bank and Gaza Strip, besides other territories. In 1964, when the West Bank was controlled by Jordan, the Palestinian National Charter of the PLO defines the boundaries of Palestine as the whole remaining territory of the mandate, including Israel. Following the Six-Day War, the PLO moved to Jordan, the October 1974 Arab League summit designated the PLO as the sole legitimate representative of the Palestinian people and reaffirmed their right to establish an independent state of urgency. In November 1974, the PLO was recognized as competent on all matters concerning the question of Palestine by the UN General Assembly granting them observer status as an entity at the UN. In spite of this decision, the PLO did not participate at the UN in its capacity of the State of Palestines government, in 1979, through the Camp David Accords, Egypt signaled an end to any claim of its own over the Gaza Strip. In July 1988, Jordan ceded its claims to the West Bank—with the exception of guardianship over Haram al-Sharif—to the PLO, in November 1988, the PLO legislature, while in exile, declared the establishment of the State of Palestine. In the month following, it was recognised by many states, including Egypt. In the Palestinian Declaration of Independence, the State of Palestine is described as being established on the Palestinian territory, the UN membership application submitted by the State of Palestine also specified that it is based on the 1967 borders. During the negotiations of the Oslo Accords, the PLO recognised Israels right to exist, after Israel took control of the West Bank from Jordan and Gaza Strip from Egypt, it began to establish Israeli settlements there. These were organised into Judea and Samaria district and Hof Aza Regional Council in the Southern District, in 1980, Israel decided to freeze elections for these councils and to establish instead Village Leagues, whose officials were under Israeli influence. Later this model became ineffective for both Israel and the Palestinians, and the Village Leagues began to break up, with the last being the Hebron League, dissolved in February 1988

Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black.

The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Geopolitics is the study of the effects of geography on international politics and international relations. Geopolitics is a method of studying foreign policy to understand, explain and these include area studies, climate, topography, demography, natural resources, and applied science of the region being evaluated. Geopolitics focuses on power in relation to geographic space. In particular, territorial waters and land territory in correlation with diplomatic history, academically, geopolitics analyses history and social science with reference to geography in relation to politics. Outside of academia, a variety of groups offer a geopolitical prognosis, including non-profit groups, critical geopolitics deconstructs classical geopolitical theories, by showing their political/ideological functions for great powers during and after the age of imperialism. Mahan distinguished a key region of the world in the Eurasian context, namely, in this zone independent countries still survived – Turkey, Persia, Afghanistan, China, and Japan. Mahan regarded those countries, located between Britain and Russia, as if between Scylla and Charybdis, of the two monsters – Britain and Russia – it was the later that Mahan considered more threatening to the fate of Central Asia. Mahan was impressed by Russias transcontinental size and strategically favorable position for southward expansion, therefore, he found it necessary for the Anglo-Saxon sea power to resist Russia. The Austro-Hungarian historian Emil Reich is considered to be the first having coined the acceptance in English as early as 1902, lea believed that while Japan moved against Far East and Russia against India, the Germans would strike at England, the center of the British Empire. He thought the Anglo-Saxons faced certain disaster from their militant opponents, sir Halford Mackinders Heartland Theory initially received little attention outside geography, but some thinkers would claim that it subsequently influenced the foreign policies of world powers. His formulation of the Heartland Theory was set out in his article entitled The Geographical Pivot of History, Mackinders doctrine of geopolitics involved concepts diametrically opposed to the notion of Alfred Thayer Mahan about the significance of navies in world conflict. He saw navy as a basis of Colombian era empire, the Heartland theory hypothesized a huge empire being brought into existence in the Heartland—which wouldnt need to use coastal or transoceanic transport to remain coherent. Mackinder posited that the centers of the Periphery were necessarily located in widely separated locations. The World Island could send its navy to destroy one of them in turn. Mackinder called this region the Heartland and it essentially comprised Central and Eastern Europe, Ukraine, Western Russia, and Mitteleuropa. The Heartland contained the grain reserves of Ukraine, and many natural resources. Mackinders notion of geopolitics was summed up when he said, Who rules Central, who rules the Heartland commands the World-Island. Who rules the World-Island commands the World, nicholas J. Spykman is both a follower and critic of geostrategists Alfred Mahan, and Halford Mackinder

Archaeology
–
Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, Archaeology can be considered both a social science and a branch of the humanities. In North America, archaeology is considered a sub-field of anthropology, archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology as a field is distinct from the discipline of palaeontology, Archaeology is particularly important for learning about prehistoric societies, for whom there may be no written records to study. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of literacy in societies across the world, Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time. The discipline involves surveying, excavation and eventually analysis of data collected to learn more about the past, in broad scope, archaeology relies on cross-disciplinary research. Archaeology developed out of antiquarianism in Europe during the 19th century, Archaeology has been used by nation-states to create particular visions of the past. Nonetheless, today, archaeologists face many problems, such as dealing with pseudoarchaeology, the looting of artifacts, a lack of public interest, the science of archaeology grew out of the older multi-disciplinary study known as antiquarianism. Antiquarians studied history with attention to ancient artifacts and manuscripts. Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment era in Europe in the 17th and 18th centuries, in Europe, philosophical interest in the remains of Greco-Roman civilization and the rediscovery of classical culture began in the late Middle Age. Antiquarians, including John Leland and William Camden, conducted surveys of the English countryside, one of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey was a pioneer archaeologist who recorded numerous megalithic and other monuments in southern England. He was also ahead of his time in the analysis of his findings and he attempted to chart the chronological stylistic evolution of handwriting, medieval architecture, costume, and shield-shapes. Excavations were also carried out in the ancient towns of Pompeii and Herculaneum and these excavations began in 1748 in Pompeii, while in Herculaneum they began in 1738. The discovery of entire towns, complete with utensils and even human shapes, however, prior to the development of modern techniques, excavations tended to be haphazard, the importance of concepts such as stratification and context were overlooked. The father of archaeological excavation was William Cunnington and he undertook excavations in Wiltshire from around 1798, funded by Sir Richard Colt Hoare. Cunnington made meticulous recordings of neolithic and Bronze Age barrows, one of the major achievements of 19th century archaeology was the development of stratigraphy. The idea of overlapping strata tracing back to successive periods was borrowed from the new geological and paleontological work of scholars like William Smith, James Hutton, the application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites

James Henry Breasted
–
James Henry Breasted was an American archaeologist, Egyptologist, and historian. After completing his PhD at the University of Berlin in 1894, in 1901 he became director of the Haskell Oriental Museum at the university, where he continued to concentrate on Egypt. In 1905 Breasted was promoted to professor, and was the first chair in Egyptology, in 1919 he became the founder of the Oriental Institute at the University of Chicago, a center for interdisciplinary study of ancient civilizations. Breasted was a field researcher, and had a productive interest in recording and interpreting ancient writings. James Henry Breasted was born on Aug.27,1865 and he was educated at North Central College, graduated in 1888, and attended Chicago Theological Seminary but transferred to Yale University to study Hebrew. He received a degree from Yale in 1891 and, on the advice of William Rainey Harper, went to University of Berlin. Erman had just established a new school of Egyptology, concentrating systematically on grammar, Breasted received his doctorate in 1894. He was the first American citizen to obtain a PhD in Egyptology, in 1894 Breasted married Frances Hart. Hart and her sisters were in Germany at the time as Breasted, learning the German language. It was a vacation as Breasted had been recruited to build a collection of Egyptian antiquities for the University of Chicago. Hart died four decades later in 1934, after which Breasted married one of her sisters, Breasted popularized the term Fertile Crescent to describe the archaeologically important area including parts of present-day Iraq, Syria, Turkey, Lebanon, Jordan, Palestine and Israel. Breasted became an instructor at the University of Chicago in 1894 soon after earning his doctorate, five years later the university agreed to his accepting an invitation from the Prussian Academy of Sciences to work on its Egyptian dictionary project. From 1899 to 1908 he did work in Egypt, which established his reputation. He began to publish articles and monographs, as well as his History of Egypt from the Earliest Times Down to the Persian Conquest in 1905. At that time he was promoted to Professor of Egyptology and Oriental History for Chicago, in 1901 Breasted was appointed director of the Haskell Oriental Museum, which had opened at the University of Chicago in 1896. Piccione wrote in the preface to its 2001 reprint, it contains certain texts. As World War I wound down, he sensed an opportunity and he wrote to John D. Rockefeller Jr. son of the major donor to the University, and proposed founding what would become the Oriental Institute. He planned a trip through the Middle East, which he suggested was ready to receive scholars

Kuwait
–
Kuwait /kuːˈweɪt/, officially the State of Kuwait, is a country in Western Asia. Situated in the edge of Eastern Arabia at the tip of the Persian Gulf, it shares borders with Iraq. As of 2016, Kuwait has a population of 4.2 million people,1.3 million are Kuwaitis and 2.9 million are expatriates, expatriates account for 70% of the population. Oil reserves were discovered in 1938, from 1946 to 1982, the country underwent large-scale modernization. In the 1980s, Kuwait experienced a period of geopolitical instability, in 1990, Kuwait was invaded by Iraq. The Iraqi occupation came to an end in 1991 after military intervention by coalition forces, at the end of the war, there were extensive efforts to revive the economy and rebuild national infrastructure. Kuwait is a constitutional emirate with a political system. It has an income economy backed by the worlds sixth largest oil reserves. The Kuwaiti dinar is the highest valued currency in the world, according to the World Bank, the country has the fourth highest per capita income in the world. The Constitution was promulgated in 1962, making Kuwait the most democratic country in the region, Kuwait ranks highly in regional metrics of gender equality, as it has the regions highest Global Gender Gap ranking. During the Ubaid period, Kuwait was the site of interaction between the peoples of Mesopotamia and Neolithic Eastern Arabia, mainly centered in As-Subiya in northern Kuwait. The earliest evidence of habitation in Kuwait dates back 8000 B. C. where Mesolithic tools were found in Burgan. As-Subiya in northern Kuwait is the earliest evidence of urbanization in the whole Persian Gulf basin area, mesopotamians first settled in the Kuwaiti island of Failaka in 2000 B. C. Traders from the Sumerian city of Ur inhabited Failaka and ran a mercantile business, the island had many Mesopotamian-style buildings typical of those found in Iraq dating from around 2000 B. C. The Neolithic inhabitants of Kuwait were among the worlds earliest maritime traders, one of the worlds earliest reed-boats was discovered in northern Kuwait dating back to the Ubaid period. In 3rd century BC, the ancient Greeks colonized the bay of Kuwait under Alexander the Great, according to Strabo and Arrian, Alexander the Great named Failaka Ikaros because it resembled the Aegean island of that name in size and shape. Remains of Greek colonization include a large Hellenistic fort and Greek temples, in 224 AD, Kuwait became part of the Sassanid Empire. At the time of the Sassanid Empire, Kuwait was known as Meshan, Akkaz was a Partho-Sassanian site, the Sassanid religions tower of silence was discovered in northern Akkaz

Levant
–
The Levant is an approximate historical geographical term referring to a large area in the Eastern Mediterranean. The term Levant entered English in the late 15th century from French and it derives from the Italian Levante, meaning rising, implying the rising of the sun in the east. As such, it is equivalent to the Arabic term Mashriq. Eventually the term was restricted to the Muslim countries of Syria-Palestine, in 1581, England set up the Levant Company to monopolize commerce with the Ottoman Empire. The name Levant States was used to refer to the French mandate over Syria and this is probably the reason why the term Levant has come to be used synonymously with Syria-Palestine. Some scholars misunderstood the term thinking that it derives from the name of Lebanon, today the term is typically used in conjunction with prehistoric or ancient historical references. It does not include Anatolia, the Caucasus Mountains, or any part of the Arabian Peninsula proper, the Sinai Peninsula is sometimes included. The Levant has been described as the crossroads of western Asia, the eastern Mediterranean, and northeast Africa, the populations of the Levant share not only the geographic position, but cuisine, some customs, and a very long history. They are often referred to as Levantines, the term Levant, which appeared in English in 1497, originally meant the East in general or Mediterranean lands east of Italy. It is borrowed from the French levant rising, referring to the rising of the sun in the east, the phrase is ultimately from the Latin word levare, meaning lift, raise. Similar etymologies are found in Greek Ἀνατολή, in Germanic Morgenland, in Italian, in Hungarian Kelet, in Spanish and Catalan Levante and Llevant, most notably, Orient and its Latin source oriens meaning east, is literally rising, deriving from Latin orior rise. The notion of the Levant has undergone a process of historical evolution in usage, meaning. While the term Levantine originally referred to the European residents of the eastern Mediterranean region, it came to refer to regional native. The English Levant Company was founded in 1581 to trade with the Ottoman Empire, at this time, the Far East was known as the Upper Levant. In early 19th-century travel writing, the term sometimes incorporated certain Mediterranean provinces of the Ottoman empire, in 19th-century archaeology, it referred to overlapping cultures in this region during and after prehistoric times, intending to reference the place instead of any one culture. The French mandate of Syria and Lebanon was called the Levant states, today, Levant is the term typically used by archaeologists and historians with reference to the history of the region. Scholars have adopted the term Levant to identify the region due to it being a wider, yet relevant, archaeologists seeking a neutral orientation that is neither biblical nor national have used terms such as Levantine archaeology and archaeology of the Southern Levant. Two academic journals were launched, Journal of Levantine Studies, published by the Van Leer Jerusalem Institute and The Levantine Review

Mediterranean Sea
–
The sea is sometimes considered a part of the Atlantic Ocean, although it is usually identified as a separate body of water. The name Mediterranean is derived from the Latin mediterraneus, meaning inland or in the middle of land and it covers an approximate area of 2.5 million km2, but its connection to the Atlantic is only 14 km wide. The Strait of Gibraltar is a strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Gibraltar. In oceanography, it is called the Eurafrican Mediterranean Sea or the European Mediterranean Sea to distinguish it from mediterranean seas elsewhere. The Mediterranean Sea has a depth of 1,500 m. The sea is bordered on the north by Europe, the east by Asia and it is located between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west-east length, from the Strait of Gibraltar to the Gulf of Iskenderun, the seas average north-south length, from Croatia’s southern shore to Libya, is approximately 800 km. The Mediterranean Sea, including the Sea of Marmara, has an area of approximately 2,510,000 square km. The sea was an important route for merchants and travelers of ancient times that allowed for trade, the history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. In addition, the Gaza Strip and the British Overseas Territories of Gibraltar and Akrotiri, the term Mediterranean derives from the Latin word mediterraneus, meaning amid the earth or between land, as it is between the continents of Africa, Asia and Europe. The Ancient Greek name Mesogeios, is similarly from μέσο, between + γη, land, earth) and it can be compared with the Ancient Greek name Mesopotamia, meaning between rivers. The Mediterranean Sea has historically had several names, for example, the Carthaginians called it the Syrian Sea and latter Romans commonly called it Mare Nostrum, and occasionally Mare Internum. Another name was the Sea of the Philistines, from the people inhabiting a large portion of its shores near the Israelites, the sea is also called the Great Sea in the General Prologue by Geoffrey Chaucer. In Ottoman Turkish, it has also been called Bahr-i Sefid, in Modern Hebrew, it has been called HaYam HaTikhon, the Middle Sea, reflecting the Seas name in ancient Greek, Latin, and modern languages in both Europe and the Middle East. Similarly, in Modern Arabic, it is known as al-Baḥr al-Mutawassiṭ, in Turkish, it is known as Akdeniz, the White Sea since among Turks the white colour represents the west. Several ancient civilisations were located around the Mediterranean shores, and were influenced by their proximity to the sea. It provided routes for trade, colonisation, and war, as well as food for numerous communities throughout the ages, due to the shared climate, geology, and access to the sea, cultures centered on the Mediterranean tended to have some extent of intertwined culture and history. Two of the most notable Mediterranean civilisations in classical antiquity were the Greek city states, later, when Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum

Jordan River
–
The Jordan River is a 251-kilometre -long river in the Middle East that flows roughly north to south through the Sea of Galilee and on to the Dead Sea. Israel and the West Bank border the river to the west, while the Golan Heights, both Jordan and the West Bank take their names from the river. The Jordan River has a course and a lower one. In this sense, the Jordan Valley may be separated into upper, central, over its upper course, the river drops rapidly in a 75-kilometre run to the once large and swampy Lake Hula, which is slightly above sea level. Exiting the now much diminished lake, it goes through an even steeper drop over the 25 kilometres down to the Sea of Galilee, the Jordan deposits much of the silt it is carrying within the lake, which it leaves again near its southern tip. At that point the river is situated about 210 metres below sea level, two major tributaries enter from the east during this last section, the Yarmouk River and Zarqa River. Its section north of the Sea of Galilee is within the boundaries of Israel, south of the lake, it forms the border between the Kingdom of Jordan, and Israel. The streams coming together to create the River Jordan in its basin are, west to east, Iyyon. Hasbani, a stream flows from Mount Lebanon. Dan, a stream whose source is also at the base of Mount Hermon, Banias, a stream arising from a spring at Banias at the foot of Mount Hermon. The full text of W. F. Lynchs 1849 book Narrative of the United States Expedition to the River Jordan, in 1964, Israel began operating a pumping station that diverts water from the Sea of Galilee to the National Water Carrier. Also in 1964, Jordan constructed a channel that diverted water from the Yarmouk River, another tributary of the Jordan River to the East Ghor Canal. Syria has also built reservoirs that catch the Yarmouks waters, environmentalists blame Israel, Jordan and Syria for extensive damage to the Jordan River ecosystem. In modern times, the waters are 70% to 90% used for human purposes, because of this and the high evaporation rate of the Dead Sea, as well as industrial extraction of salts through evaporation ponds, the sea is shrinking. All the shallow waters of the end of the sea have been drained in modern times and are now salt flats. A small section of the northernmost portion of the Lower Jordan, 3-kilometre below the Sea of Galilee, has been kept pristine for baptism and local tourism. Most polluted is the 100-kilometre downstream stretch—a meandering stream from above the confluence with the Yarmouk to the Dead Sea, environmentalists say the practice of letting sewage and brackish water flow into the river has almost destroyed its ecosystem. Rescuing the Jordan could take decades, according to environmentalists, the same environmentalist organization had said in a report that the Jordan River could dry up by 2011 unless the decay is stopped

Syrian Desert
–
To the south it borders and merges into the Arabian Desert. The land is open, gravely desert pavement, cut with occasional wadis, the desert is bounded by the Orontes Valley and volcanic field of Harrat al-Shamah to the west, and by the Euphrates to the east. In the north, the desert gives way to the fertile areas of grass. Several parts of the Syrian Desert have been referred to such as the Palmyrene desert around Palmyra. The name Shamiyah has also used for the Syrian Desert. The 700-900m high region in the middle of the desert is the Hamad Plateau, what little rain arrives on the plateau flows into local salt flats. The highest peaks of the Plateau are those of the 1000m+ Khawr um Wual in Saudi Arabia, together with the other deserts of the Arabian Peninsular, the Hamad Desert has been described as one of the most arid deserts of the world. The Syrian Desert is the origin of the Syrian hamster, storks, herons, cranes, small waders, waterfowl and also raptors visit the seasonal lakes. The large mammals are now no longer to be found, thought to be due to hunting by man, the desert was historically inhabited by Bedouin tribes, and many tribes still remain in the region, their members living mainly in towns and settlements built near oases. Some Bedouin still maintain their way of life in the desert. Safaitic inscriptions, proto-Arabic texts written by literate Bedouin, are throughout the Syrian Desert. These date approximately from the 1st century B. C. to the 4th century A. D, the desert was first traversed by motor vehicle in 1919. A series of Coalition military operations were ineffective at removing the resistance presence in the Desert. Arabian desert Fertile Crescent List of deserts by area Syrian steppe

Anatolia
–
Anatolia, in geography known as Asia Minor, Asian Turkey, Anatolian peninsula, or Anatolian plateau, is the westernmost protrusion of Asia, which makes up the majority of modern-day Turkey. The region is bounded by the Black Sea to the north, the Mediterranean Sea to the south, the Sea of Marmara forms a connection between the Black and Aegean Seas through the Bosphorus and Dardanelles straits and separates Anatolia from Thrace on the European mainland. Traditionally, Anatolia is considered to extend in the east to a line between the Gulf of Alexandretta and the Black Sea to the Armenian Highlands, thus, traditionally Anatolia is the territory that comprises approximately the western two-thirds of the Asian part of Turkey. The Turkification of Anatolia began under the Seljuk Empire in the late 11th century, however, various non-Turkic languages continue to be spoken by minorities in Anatolia today, including Kurdish, Assyrian, Armenian, Arabic, Laz, Georgian, and Greek. Traditionally, Anatolia is considered to extend in the east to a line running from the Gulf of Alexandretta to the Black Sea. This traditional geographical definition is used, for example, in the latest edition of Merriam-Websters Geographical Dictionary, under this definition, Anatolia is bounded to the east by the Armenian Highlands, and the Euphrates before that river bends to the southeast to enter Mesopotamia. To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria, the first name the Greeks used for the Anatolian peninsula was Ἀσία, presumably after the name of the Assuwa league in western Anatolia. As the name of Asia came to be extended to areas east of the Mediterranean. The name Anatolia derives from the Greek ἀνατολή meaning “the East” or more literally “sunrise”, the precise reference of this term has varied over time, perhaps originally referring to the Aeolian, Ionian and Dorian colonies on the west coast of Asia Minor. In the Byzantine Empire, the Anatolic Theme was a theme covering the western, the modern Turkish form of Anatolia is Anadolu, which again derives from the Greek name Aνατολή. The Russian male name Anatoly and the French Anatole share the same linguistic origin, in English the name of Turkey for ancient Anatolia first appeared c. It is derived from the Medieval Latin Turchia, which was used by the Europeans to define the Seljuk controlled parts of Anatolia after the Battle of Manzikert. Human habitation in Anatolia dates back to the Paleolithic, neolithic Anatolia has been proposed as the homeland of the Indo-European language family, although linguists tend to favour a later origin in the steppes north of the Black Sea. However, it is clear that the Anatolian languages, the oldest branch of Indo-European, have spoken in Anatolia since at least the 19th century BC. The earliest historical records of Anatolia stem from the southeast of the region and are from the Mesopotamian-based Akkadian Empire during the reign of Sargon of Akkad in the 24th century BC, scholars generally believe the earliest indigenous populations of Anatolia were the Hattians and Hurrians. The region was famous for exporting raw materials, and areas of Hattian-, one of the numerous cuneiform records dated circa 20th century BC, found in Anatolia at the Assyrian colony of Kanesh, uses an advanced system of trading computations and credit lines. They were speakers of an Indo-European language, the Hittite language, originating from Nesa, they conquered Hattusa in the 18th century BC, imposing themselves over Hattian- and Hurrian-speaking populations. According to the most widely accepted Kurgan theory on the Proto-Indo-European homeland, however, the Hittites adopted the cuneiform script, invented in Mesopotamia

Sahara
–
The Sahara is the largest hot desert and the third largest desert in the world after Antarctica and the Arctic. Its area of 9,200,000 square kilometres is comparable to the area of the United States. The desert comprises much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile Valley in Egypt and Sudan. It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south, it is bounded by the Sahel, a belt of tropical savanna around the Niger River valley. The Sahara can be divided into several regions including, the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains, the Ténéré desert, the name Sahara is derived from ṣaḥārā, the plural of the Arabic word for desert. The Sahara covers large parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and it covers 9 million square kilometres, amounting to 31% of Africa. If all areas with an annual precipitation of less than 250 mm were included. It is one of three physiographic provinces of the African massive physiographic division. The Sahara is mainly rocky hamada, Ergs form only a minor part, wind or rare rainfall shape the desert features, sand dunes, dune fields, sand seas, stone plateaus, gravel plains, dry valleys, dry lakes, and salt flats. Unusual landforms include the Richat Structure in Mauritania, several deeply dissected mountains, many volcanic, rise from the desert, including the Aïr Mountains, Ahaggar Mountains, Saharan Atlas, Tibesti Mountains, Adrar des Iforas, and the Red Sea hills. The highest peak in the Sahara is Emi Koussi, a volcano in the Tibesti range of northern Chad. The central Sahara is hyperarid, with sparse vegetation, the northern and southern reaches of the desert, along with the highlands, have areas of sparse grassland and desert shrub, with trees and taller shrubs in wadis, where moisture collects. In the central, hyperarid region, there are subdivisions of the great desert, Tanezrouft, the Ténéré, the Libyan Desert, the Eastern Desert. These extremely arid areas often receive no rain for years, the northern limit also corresponds to the 100 mm isohyet of annual precipitation. To the south, the Sahara is bounded by the Sahel, the southern limit of the Sahara is indicated botanically by the southern limit of Cornulaca monacantha, or northern limit of Cenchrus biflorus, a grass typical of the Sahel. According to climatic criteria, the limit of the Sahara corresponds to the 150 mm isohyet of annual precipitation. The Sahara is the worlds largest low-latitude hot desert and this steady descending airflow causes a warming and a drying effect in the upper troposphere

Marsh
–
A marsh is a wetland that is dominated by herbaceous rather than woody plant species. Marshes can often be found at the edges of lakes and streams and they are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, Marshes provide a habitat for many species of plants, animals, and insects that have adapted to living in flooded conditions. The plants must be able to survive in wet mud with low oxygen levels, many of these plants therefore have aerenchyma, channels within the stem that allow air to move from the leaves into the rooting zone. Marsh plants also tend to have rhizomes for underground storage and reproduction, familiar examples include cattails, sedges, papyrus and sawgrass. Aquatic animals, from fish to salamanders, are able to live with a low amount of oxygen in the water. Some can obtain oxygen from the air instead, while others can live indefinitely in conditions of low oxygen, Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. Marshes have extremely high levels of production, some of the highest in the world. Marshes also improve water quality by acting as a sink to filter pollutants, Marshes are able to absorb water during periods of heavy rainfall and slowly release it into waterways and therefore reduce the magnitude of flooding. The pH in marshes tends to be neutral to alkaline, as opposed to bogs, Marshes differ depending mainly on their location and salinity. Both of these factors influence the range and scope of animal and plant life that can survive. The three main types of marsh are salt marshes, freshwater marshes, and freshwater marshes. These three can be found worldwide and each contains a different set of organisms, saltwater marshes are found around the world in mid to high latitudes, wherever there are sections of protected coastline. They are located close enough to the shoreline that the motion of the tides affects them and they flourish where the rate of sediment buildup is greater than the rate at which the land level is sinking. Salt marshes are dominated by specially adapted rooted vegetation, primarily salt-tolerant grasses, salt marshes are most commonly found in lagoons, estuaries, and on the sheltered side of shingle or sandspit. The currents there carry the fine particles around to the side of the spit. These locations allow the marshes to absorb the nutrients from the water running through them before they reach the oceans. Coastal development and urban sprawl has caused significant loss of these essential habitats, although considered a freshwater marsh, this form of marsh is affected by the ocean tides

Africa
–
Africa is the worlds second-largest and second-most-populous continent. At about 30.3 million km² including adjacent islands, it covers 6% of Earths total surface area and 20.4 % of its land area. With 1.2 billion people as of 2016, it accounts for about 16% of the human population. The continent includes Madagascar and various archipelagos and it contains 54 fully recognized sovereign states, nine territories and two de facto independent states with limited or no recognition. Africas population is the youngest amongst all the continents, the age in 2012 was 19.7. Algeria is Africas largest country by area, and Nigeria by population, afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens found in Ethiopia being dated to circa 200,000 years ago. Africa straddles the equator and encompasses numerous climate areas, it is the continent to stretch from the northern temperate to southern temperate zones. Africa hosts a diversity of ethnicities, cultures and languages. In the late 19th century European countries colonized most of Africa, Africa also varies greatly with regard to environments, economics, historical ties and government systems. However, most present states in Africa originate from a process of decolonization in the 20th century, afri was a Latin name used to refer to the inhabitants of Africa, which in its widest sense referred to all lands south of the Mediterranean. This name seems to have referred to a native Libyan tribe. The name is connected with Hebrew or Phoenician ʿafar dust. The same word may be found in the name of the Banu Ifran from Algeria and Tripolitania, under Roman rule, Carthage became the capital of the province of Africa Proconsularis, which also included the coastal part of modern Libya. The Latin suffix -ica can sometimes be used to denote a land, the later Muslim kingdom of Ifriqiya, modern-day Tunisia, also preserved a form of the name. According to the Romans, Africa lay to the west of Egypt, while Asia was used to refer to Anatolia, as Europeans came to understand the real extent of the continent, the idea of Africa expanded with their knowledge. 25,4, whose descendants, he claimed, had invaded Libya, isidore of Seville in Etymologiae XIV.5.2. Suggests Africa comes from the Latin aprica, meaning sunny, massey, in 1881, stated that Africa is derived from the Egyptian af-rui-ka, meaning to turn toward the opening of the Ka. The Ka is the double of every person and the opening of the Ka refers to a womb or birthplace

Eurasia
–
Eurasia /jʊˈreɪʒə/ is a combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents, in geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data, Eurasia covers around 55,000,000 square kilometres, or around 36. 2% of the Earths total land area. The landmass contains around 5.0 billion people, equating to approximately 70% of the human population, humans first settled in Eurasia between 60,000 and 125,000 years ago. Physiographically, Eurasia is a single continent, the concepts of Europe and Asia as distinct continents date back to antiquity and their borders are geologically arbitrary. Eurasia is connected to Africa at the Suez Canal, and Eurasia is sometimes combined with Africa as the largest contiguous landmass on Earth called Afro-Eurasia. Eurasia formed 375 to 325 million years ago with the merging of Siberia, Kazakhstania, and Baltica, chinese cratons collided with Siberias southern coast. Eurasia has been the host of ancient civilizations, including those based in Mesopotamia. In the Axial Age, a belt of civilizations stretched through the Eurasian subtropical zone from the Atlantic to the Pacific. This belt became the mainstream of world history for two millennia, originally, “Eurasia” is a geographical notion, in this sense, it is simply the biggest continent, the combined landmass of Europe and Asia. However, geopolitically, the word has different meanings, reflecting the specific geopolitical interests of each nation. “Eurasia” is one of the most important geopolitical concepts, as Zbigniew Brzezinski observed, how America manages Eurasia is critical. A power that dominates “Eurasia” would control two of the three most advanced and economically productive regions. About 75 per cent of the people live in “Eurasia”. “Eurasia” accounts for about three-fourths of the known energy resources. ”At the moment one of the most prominent projects of the European Union is the Russia - EU Four Common Spaces Initiative. A political and economic union of former Soviet states named the Eurasian Economic Union was established in 2015, the Russian concept of “Eurasia” corresponded initially more or less to the land area of Imperial Russia in 1914, including parts of Eastern Europe. One of Russias main geopolitical interests lies in ever closer integration with those countries that it considers part of “Eurasia. ”Every two years since 1996 a meeting of most Asian and European countries is organised as the Asia-Europe Meeting. In ancient times, the Greeks classified Europe and Asia as separate lands, where to draw the dividing line between the two regions is still a matter of discussion

Biodiversity
–
Biodiversity, a contraction of biological diversity, generally refers to the variety and variability of life on Earth. One of the most widely used definitions defines it in terms of the variability within species and it is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation within an area, biome, terrestrial biodiversity tends to be greater near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richest in the tropics and these tropical forest ecosystems cover less than 10 per cent of earths surface, and contain about 90 percent of the worlds species. Marine biodiversity tends to be highest along coasts in the Western Pacific, there are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, the number and variety of plants, animals and other organisms that exist is known as biodiversity. It is a component of nature and it ensures the survival of human species by providing food, fuel, shelter, medicines. The richness of biodiversity depends on the conditions and area of the region. All species of plants taken together are known as flora and about 300,000 species of plants are known to date, all species of animals taken together are known as fauna which includes birds, mammals, fish, reptiles, insects, crustaceans, molluscs, etc. Rapid environmental changes typically cause mass extinctions, more than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct. Estimates on the number of Earths current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described, the total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes. In comparison, the mass of the biosphere has been estimated to be as much as 4 TtC. In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor of all living on Earth. The age of the Earth is about 4.54 billion years old, there are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. Other early physical evidence of a substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland. More recently, in 2015, remains of life were found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, If life arose relatively quickly on Earth, then it could be common in the universe

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

North Africa
–
North Africa or Northern Africa is the northernmost region of Africa. The United Nationss definition of Northern Africa is, Algeria, Egypt, Libya, Morocco, Sudan, Tunisia, the countries of Algeria, Morocco, Tunisia, and Libya are often collectively referred to as the Maghreb, which is the Arabic word for sunset. Egypt lies to the northeast and encompasses part of West Asia, while Sudan is situated on the edge of the Sahel, Egypt is a transcontinental country because of the Sinai Peninsula, which geographically lies in Western Asia. North Africa also includes a number of Spanish possessions, the Canary Islands and Madeira in the North Atlantic Ocean northwest of the African mainland are included in considerations of the region. From 3500 BC, following the abrupt desertification of the Sahara due to changes in the Earths orbit. The Islamic influence in the area is significant, and North Africa is a major part of the Muslim world. Some researchers have postulated that North Africa rather than East Africa served as the point for the modern humans who first trekked out of the continent in the Out of Africa migration. The Atlas Mountains extend across much of Morocco, northern Algeria and Tunisia, are part of the mountain system that also runs through much of Southern Europe. They recede to the south and east, becoming a steppe landscape before meeting the Sahara desert, the sediments of the Sahara overlie an ancient plateau of crystalline rock, some of which is more than four billion years old. Sheltered valleys in the Atlas Mountains, the Nile Valley and Delta, a wide variety of valuable crops including cereals, rice and cotton, and woods such as cedar and cork, are grown. Typical Mediterranean crops, such as olives, figs, dates and citrus fruits, the Nile Valley is particularly fertile, and most of the population in Egypt and Sudan live close to the river. Elsewhere, irrigation is essential to improve yields on the desert margins. The inhabitants of Saharan Africa are generally divided in a manner corresponding to the principal geographic regions of North Africa, the Maghreb, the Nile valley. The edge of the Sahel, to the south of Egypt has mainly been inhabited by Nubians, Ancient Egyptians record extensive contact in their Western desert with people that appear to have been Berber or proto-Berber, as well as Nubians from the south. They have contributed to the Arabized Berber populations, the official language or one of the official languages in all of the countries in North Africa is Arabic. The people of the Maghreb and the Sahara regions speak Berber languages and several varieties of Arabic, the Arabic and Berber languages are distantly related, both being members of the Afroasiatic language family. The Tuareg Berber languages are more conservative than those of the coastal cities. Over the years, Berbers have been influenced by contact with cultures, Greeks, Phoenicians, Egyptians, Romans, Vandals, Arabs, Europeans

Climate change
–
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change may refer to a change in weather conditions. Climate change is caused by such as biotic processes, variations in solar radiation received by Earth, plate tectonics. Certain human activities have also identified as significant causes of recent climate change. Scientists actively work to understand past and future climate by using observations, more recent data are provided by the instrumental record. The most general definition of change is a change in the statistical properties of the climate system when considered over long periods of time. Accordingly, fluctuations over periods shorter than a few decades, such as El Niño, the term climate change is often used to refer specifically to anthropogenic climate change. Anthropogenic climate change is caused by activity, as opposed to changes in climate that may have resulted as part of Earths natural processes. In this sense, especially in the context of environmental policy, within scientific journals, global warming refers to surface temperature increases while climate change includes global warming and everything else that increasing greenhouse gas levels affect. A related term is climatic change, in 1966, the World Meteorological Organization proposed the term climatic change to encompass all forms of climatic variability on time-scales longer than 10 years, regardless of cause. Change was a given and climatic was used as an adjective to describe this kind of change, when it was realized that human activities had a potential to drastically alter the climate, the term climate change replaced climatic change as the dominant term to reflect an anthropogenic cause. Climate change was incorporated in the title of the Intergovernmental Panel on Climate Change, Climate change, used as a noun, became an issue rather than the technical description of changing weather. On the broadest scale, the rate at which energy is received from the Sun and this energy is distributed around the globe by winds, ocean currents, and other mechanisms to affect the climates of different regions. Factors that can shape climate are called climate forcings or forcing mechanisms, there are a variety of climate change feedbacks that can either amplify or diminish the initial forcing. Some parts of the system, such as the oceans and ice caps, respond more slowly in reaction to climate forcings. There are also key factors which when exceeded can produce rapid change. Forcing mechanisms can be internal or external. Internal forcing mechanisms are natural processes within the system itself

Ice age
–
An ice age is a period of long-term reduction in the temperature of Earths surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed glacial periods, in the terminology of glaciology, ice age implies the presence of extensive ice sheets in both northern and southern hemispheres. In 1742 Pierre Martel, an engineer and geographer living in Geneva, two years later he published an account of his journey. He reported that the inhabitants of that valley attributed the dispersal of erratic boulders to the glaciers, later similar explanations were reported from other regions of the Alps. In 1815 the carpenter and chamois hunter Jean-Pierre Perraudin explained erratic boulders in the Val de Bagnes in the Swiss canton of Valais as being due to glaciers previously extending further. An unknown woodcutter from Meiringen in the Bernese Oberland advocated a similar idea in a discussion with the Swiss-German geologist Jean de Charpentier in 1834, comparable explanations are also known from the Val de Ferret in the Valais and the Seeland in western Switzerland and in Goethes scientific work. Such explanations could also be found in parts of the world. When the Bavarian naturalist Ernst von Bibra visited the Chilean Andes in 1849–1850, meanwhile, European scholars had begun to wonder what had caused the dispersal of erratic material. From the middle of the 18th century, some discussed ice as a means of transport, the Swedish mining expert Daniel Tilas was, in 1742, the first person to suggest drifting sea ice in order to explain the presence of erratic boulders in the Scandinavian and Baltic regions. In 1795, the Scottish philosopher and gentleman naturalist, James Hutton, two decades later, in 1818, the Swedish botanist Göran Wahlenberg published his theory of a glaciation of the Scandinavian peninsula. He regarded glaciation as a regional phenomenon, only a few years later, the Danish-Norwegian geologist Jens Esmark argued a sequence of worldwide ice ages. In a paper published in 1824, Esmark proposed changes in climate as the cause of those glaciations and he attempted to show that they originated from changes in Earths orbit. During the following years, Esmarks ideas were discussed and taken over in parts by Swedish, Scottish, at the University of Edinburgh Robert Jameson seemed to be relatively open to Esmarks ideas, as reviewed by Norwegian professor of glaciology Bjørn G. Andersen. Jamesons remarks about ancient glaciers in Scotland were most probably prompted by Esmark, in Germany, Albrecht Reinhard Bernhardi, a geologist and professor of forestry at an academy in Dreissigacker, since incorporated in the southern Thuringian city of Meiningen, adopted Esmarks theory. In a paper published in 1832, Bernhardi speculated about former polar ice caps reaching as far as the zones of the globe. When he read his paper before the Schweizerische Naturforschende Gesellschaft, most scientists remained sceptical, finally, Venetz convinced his friend Jean de Charpentier. De Charpentier transformed Venetzs idea into a theory with a limited to the Alps. In fact, both men shared the same volcanistic, or in de Charpentiers case rather plutonistic assumptions, about the Earths history, in 1834, de Charpentier presented his paper before the Schweizerische Naturforschende Gesellschaft

Extinction
–
In biology and ecology, extinction is the end of an organism or of a group of organisms, normally a species. The moment of extinction is considered to be the death of the last individual of the species, although the capacity to breed. Because a species range may be very large, determining this moment is difficult. This difficulty leads to such as Lazarus taxa, where a species presumed extinct abruptly reappears after a period of apparent absence. More than 99 percent of all species, amounting to five billion species. Estimates on the number of Earths current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described, the relationship between animals and their ecological niches has been firmly established. Mass extinctions are relatively rare events, however, isolated extinctions are quite common, only recently have extinctions been recorded and scientists have become alarmed at the current high rate of extinctions. Most species that become extinct are never scientifically documented, some scientists estimate that up to half of presently existing plant and animal species may become extinct by 2100. A dagger symbol next to a name is often used to indicate its extinction. A species is extinct when the last existing member dies, Extinction therefore becomes a certainty when there are no surviving individuals that can reproduce and create a new generation. Pinpointing the extinction of a species requires a definition of that species. If it is to be declared extinct, the species in question must be distinguishable from any ancestor or daughter species. Extinction of a plays a key role in the punctuated equilibrium hypothesis of Stephen Jay Gould. In ecology, extinction is often used informally to refer to local extinction, in which a species ceases to exist in the area of study. This phenomenon is known as extirpation. Local extinctions may be followed by a replacement of the species taken from other locations, species which are not extinct are termed extant. Those that are extant but threatened by extinction are referred to as threatened or endangered species, currently an important aspect of extinction is human attempts to preserve critically endangered species

Sahara pump theory
–
The Sahara pump theory is a hypothesis that explains how flora and fauna migrated between Eurasia and Africa via a land bridge in the Levant region. It posits that extended periods of abundant rainfall lasting many thousands of years in Africa are associated with a phase, during which larger lakes. This caused changes in the flora and fauna found in the area, during periods of a wet or Green Sahara, the Sahara and Arabia become a savanna grassland and African flora and fauna become common. Following inter-pluvial arid periods, the Sahara area then reverts to desert conditions, evaporation exceeds precipitation, the level of water in lakes like Lake Chad falls, and rivers become dry wadis. This separates populations of some of the species in areas with different climates, forcing them to adapt, possibly giving rise to allopatric speciation. The Plio-Pleistocene migrations to Africa included the Caprinae in two waves at 3.2 Ma and 2. 7-2.5 Ma, Nyctereutes at 2.5 Ma, hippotragus migrated at 2.6 Ma from Africa to the Siwaliks of the Himalayas. Asian bovids moved to Europe and to and from Africa, the primate Theropithecus experienced contraction and its fossils are found only in Europe and Asia, while Homo and Macaca settled wide ranges. This allowed Eurasian biota to travel to Africa and vice versa, the growth of speleothems was detected in Hol-Zakh, Ashalim, Even-Sid, Maale-ha-Meyshar, Ktora Cracks, Nagev Tzavoa Cave. The Red Sea coastal route was extremely arid before 140 and after 115 kya, slightly wetter conditions appear at 90–87 kya, but it still was just one tenth the rainfall around 125 kya. Speleothems are detected only in Even-Sid-2, in the southern Negev Desert speleothems did not grow between 185–140 kya, 110-90, nor after 85 kya nor during most of the interglacial period, the glacial period and Holocene. This suggests that the southern Negev was arid to hyper-arid in these periods, the coastal route around the western Mediterranean may have been open at times during the last glacial, speleothems grew in Hol-Zakh and in Nagev Tzavoa Caves. Comparison of speleothem formation with calcite horizons suggests that the wet periods were limited to tens or hundreds of years. From 60–30 kya there were extremely dry conditions in parts of Africa. An example of the Saharan pump has occurred after the Last Glacial Maximum, during the Last Glacial Maximum the Sahara desert was more extensive than it is now with the extent of the tropical forests being greatly reduced. This phase is associated with rates of wind-blown mineral dust. Around 12,500 BC, the amount of dust in the cores in the Bølling/Allerød phase suddenly plummets and shows a period of much wetter conditions in the Sahara, indicating a Dansgaard-Oeschger event. This was caused principally by a monsoonal circulation throughout the sub-tropical regions, affecting India, Arabia. Lake Victoria only recently became the source of the White Nile and this is linked to a marked decline in the scale of the Nile floods between 2700 and 2100 BC

Old World
–
The Old World consists of Africa, Europe, and Asia, regarded collectively as the part of the world known to Europeans before contact with the Americas. It is used in the context of, and contrast with and these regions were connected via the Silk Road trade route, and they have a pronounced Iron Age period following the Bronze Age. The concept of the three continents in the Old World, viz. Asia, Africa, and Europe, goes back to classical antiquity and their boundaries as defined by Ptolemy and other geographers of antiquity were drawn along the Nile and Don rivers. This definition remained influential throughout the Middle Ages and the Early Modern period, the Old world has areas of North Africa, Eurasia, parts of Papua New Guinea and Solomon Islands. The mainland of Afro-Eurasia has been referred to as the World Island, the term may have been coined by Sir Halford John Mackinder in The Geographical Pivot of History. The equivalent of the Old World had names in some of its ancient cultures, including Midgard in Germanic cosmology, synoptic table of the principal old world prehistoric cultures Afro-Eurasia
46.
Flora
–
Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenous—native plant life. The corresponding term for animal life is fauna, Flora, fauna and other forms of life such as fungi are collectively referred to as biota. Sometimes bacteria and fungi are also referred to as flora, as in the gut flora or skin flora. The word flora comes from the Latin name of Flora, the goddess of plants, flowers, the distinction between vegetation and flora was first made by Jules Thurmann. Prior to this, the two terms were used indiscriminately, plants are grouped into floras based on region, period, special environment, or climate. Regions can be geographically distinct habitats like mountain vs. flatland, floras can mean plant life of a historic era as in fossil flora. Lastly, floras may be subdivided by special environments, Native flora, the native and indigenous flora of an area. The plants that are grown by humans. Traditionally this classification was applied to plants regarded as undesirable, many native plants previously considered weeds have been shown to be beneficial or even necessary to various ecosystems. The flora of an area or time period can be documented in a publication also known as a flora. Floras may require specialist botanical knowledge to use with any effectiveness, traditionally they are books, but some are now published on CD-ROM or websites. It is said that the Flora Sinensis by the Polish Jesuit Michał Boym was the first book that used the name Flora in this meaning, however, despite its title it covered not only plants, but also some animals of the region. A published flora often contains diagnostic keys, often these are dichotomous keys, which require the user to repeatedly examine a plant, and decide which one of two alternatives given best applies to the plant
47.
Fauna
–
Fauna is all of the animal life of any particular region or time. The corresponding term for plants is flora, flora, fauna and other forms of life such as fungi are collectively referred to as biota. Zoologists and paleontologists use fauna to refer to a collection of animals found in a specific time or place. Paleontologists sometimes refer to a sequence of stages, which is a series of rocks all containing similar fossils. Fauna comes from the Greek names Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, all three words are cognates of the name of the Greek god Pan, and panis is the Greek equivalent of fauna. Fauna is also the word for a book that catalogues the animals in such a manner, the term was first used by Carl Linnaeus from Sweden in the title of his 1745 work Fauna Suecica. Cryofauna are animals that live in, or very close to, cryptofauna are the fauna that exist in protected or concealed microhabitats. Infauna are benthic organisms that live within the substratum of a body of water, especially within the bottom-most oceanic sediments. Bacteria and microalgae may also live in the interstices of bottom sediments, epifauna, also called epibenthos, are aquatic animals that live on the bottom substratum as opposed to within it, that is, the benthic fauna that live on top of the sediment surface at the seafloor. Macrofauna are benthic or soil organisms which are retained on a 0.5 mm sieve, studies in the deep sea define macrofauna as animals retained on a 0.3 mm sieve to account for the small size of many of the taxa. Megafauna are large animals of any region or time. Meiofauna are small invertebrates that live in both marine and fresh water environments. The term Meiofauna loosely defines a group of organisms by their size, larger than microfauna but smaller than macrofauna, one environment for meiofauna is between grains of damp sand. In practice these are metazoan animals that can pass unharmed through a 0.5 –1 mm mesh but will be retained by a 30–45 μm mesh, but the exact dimensions will vary from researcher to researcher. Whether an organism passes through a 1 mm mesh also depends upon whether it is alive or dead at the time of sorting, mesofauna are macroscopic soil invertebrates such as arthropods or nematodes. Mesofauna are extremely diverse, considering just the springtails, as of 1998, microfauna are microscopic or very small animals. Other terms include avifauna, which means bird fauna and piscifauna, which means fish fauna

Early human migrations
–
Earliest human migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of Homo erectus. This was followed by the migrations of other humans including H. heidelbergensis. Finally, Homo sapiens ventured out of Africa around 100,000 years ago, spread across Asia around 60,000 years ago and arrived on new continents, cultural and ethnic migrations are estimated by combining archaeogenetics and comparative linguistics. Key sites for this early migration out of Africa are Riwat in Pakistan, Ubeidiya in the Levant, China was populated as early as 1.66 Mya based on stone artifacts found in the Nihewan Basin. The archaeological site of Xihoudu in Shanxi Province is the earliest recorded use of fire by Homo erectus, Southeast Asia was reached about 1.7 million years ago. Western Europe was first populated around 1.2 million years ago, robert G. Bednarik has suggested that Homo erectus may have built rafts and sailed oceans, a theory that has raised some controversy. Homo sapiens seems to have appeared in East Africa around 200,000 years ago, the oldest individuals found left their marks in the Omo remains and the Homo sapiens idaltu, that was found at the Middle Awash site in Ethiopia. When modern humans reached the Near East 125,000 years ago, evidence suggests they retreated back to Africa, as their settlements were replaced by Neanderthals. It is now believed that the first modern humans to spread east across Asia left Africa about 75,000 years ago across the Bab el Mandib connecting Ethiopia and Yemen. H. sapiens reached Europe around 43,000 years ago, East Asia was reached by 30,000 years ago. Colonization of the Pacific islands of Polynesia began around 1300 BC, the ancestors of Polynesians left Taiwan around 5,200 years ago. More recent migrations of language and culture groups within the species are also studied and hypothetised. The people of the Afro-Asiatic language family seem to have reached Africa in 6,200 BC, from there they spread around the world. There is evidence from mitochondrial DNA that modern humans have passed through at least one genetic bottleneck, climatological and geological evidence suggests evidence for the bottleneck. The explosion of Lake Toba created a 1,000 year cold period, as a result of the largest volcanic eruption of the Quaternary and it has been estimated that as few as 15,000 humans survived. In such circumstances genetic drift and founder effects may have been maximised, the greater diversity amongst African genomes may be in part due to the greater prevalence of African refugia during the Toba incident. The most recent common ancestor shared by all living beings, dubbed Mitochondrial Eve, probably lived roughly 120–150 millennia ago. The research also located the origin of human migration in south-western Africa, near the coastal border of Namibia

Divergent boundary
–
In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys, most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates apart to produce gaps which molten lava rises to fill. Current research indicates that complex convection within the Earths mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary. This supplies the area with vast amounts of heat and a reduction in pressure that melts rock from the asthenosphere beneath the area forming large flood basalt or lava flows. Each eruption occurs in only a part of the boundary at any one time. Over millions of years, tectonic plates may move many hundreds of kilometers away from both sides of a divergent plate boundary, because of this, rocks closest to a boundary are younger than rocks further away on the same plate. At divergent boundaries, two plates move apart from other and the space that this creates is filled with new crustal material sourced from molten magma that forms below. The origin of new divergent boundaries at triple junctions is thought to be associated with the phenomenon known as hotspots. Here, exceedingly large convective cells bring very large quantities of hot asthenospheric material near the surface, the hot spot which may have initiated the Mid-Atlantic Ridge system currently underlies Iceland which is widening at a rate of a few centimeters per year. Divergent boundaries can create massive fault zones in the ridge system. Spreading is generally not uniform, so where spreading rates of adjacent ridge blocks are different and these are the fracture zones, many bearing names, that are a major source of submarine earthquakes. A sea floor map will show a strange pattern of blocky structures that are separated by linear features perpendicular to the ridge axis. If one views the sea floor between the zones as conveyor belts carrying the ridge on each side of the rift away from the spreading center the action becomes clear. Crest depths of the old ridges, parallel to the current spreading center and it is at mid-ocean ridges that one of the key pieces of evidence forcing acceptance of the seafloor spreading hypothesis was found. Airborne geomagnetic surveys showed a pattern of symmetrical magnetic reversals on opposite sides of ridge centers. The pattern was far too regular to be coincidental as the widths of the bands were too closely matched. Scientists had been studying polar reversals and the link was made by Lawrence W. Morley, Frederick John Vine, the magnetic banding directly corresponds with the Earths polar reversals
