Atapuerca, Province of Burgos
–
Atapuerca is a municipality and town located in the province of Burgos, Castile and León, Spain. According to the 2005 census, the municipality has a population of 195 inhabitants and it encompasses the Archaeological Site of Atapuerca and is famous for its prehistoric archaeological sites. The municipality of Atapuerca is made up of two towns, Atapuerca and Olmos de Atapuerca, the small town plays host to an annual cross country running event—the Cross de Atapuerca—which attracts over 2000 runners each year. On November 30,2000, Atapuerca was declared a World Heritage by UNESCO, the Archaeological Site of Atapuerca is the only one in Europe where it is possible to follow the evolution of the first human beings to inhabit the European Continent. In 1899 construction a of new railway unveiled several significant archaeological sites, media related to Atapuerca at Wikimedia Commons

Province of Burgos
–
The province of Burgos is a province of northern Spain, in the northeastern part of the autonomous community of Castile and León. It is bordered by the provinces of Palencia, Cantabria, Vizcaya, Álava, La Rioja, Soria, Segovia and its capital is the city of Burgos. The Cartularies of Valpuesta from the monastery Santa María de Valpuesta, the site has been designated a UNESCO World Heritage Site. The province has an area of 14,300 km² and a population of approximately 375,000 of whom nearly half live in the capital, the other locations higher than 20,000 inhabitants apart from Burgos are Miranda de Ebro and Aranda de Duero, both very industrialized. The Sierra de la Demanda, the northwesternmost end of the Sistema Ibérico, is located in Burgos Province, the most important rivers in the province are the Ebro and the Duero. The river Duero is in the south of the province and leads to the Atlantic Ocean at Porto, planted near it is a notable vineyard, Ribera de Duero. The north and south-east of the province are mountainous, the Ebro flows to the Mediterranean Sea. In Valpuesta the oldest texts in the Spanish language has been found, transportation is developed through a wide net of highways and roads. Besides, the province is served by the Burgos Airport, in the Bureba Pass area, archaeologists have found evidence of occupation by hominids and humans for more than one million years. Discoveries have included the earliest hominid skull in Europe, the Celtiberian region that became Burgos was inhabited by the Morgobos, Turmodigi, Berones and perhaps also the Pellendones, the last inhabitants of the northern part of the Celtiberian region. According to the Greek historian Ptolemy, the cities included, Brabum, Sisara, Deobrigula, Ambisna Segiasamon. Under Roman colonization, it was part of Hispania Citerior and then Hispania Tarraconensis, in the fifth century, the Visigoths drove back the Suevi. In the eighth century, the Arabs occupied all of Castiles, alfonso III the Great, king of León reconquered the area around the middle of the ninth century, and built many castles for the defence of Christendom. The region came to be known as Castile, i. e. land of castles, in the eleventh century, Burgos became the capital of the Kingdom of Castile. The province of Burgos is divided in 10 comarcas, list of municipalities in Burgos Media related to Province of Burgos at Wikimedia Commons Website of the Autonomous Community of Castile and León Website of the Province of Burgos delegation

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Paleolithic
–
It extends from the earliest known use of stone tools, probably by Homo habilis initially,2.6 million years ago, to the end of the Pleistocene around 10,000 BP. The Paleolithic era is followed by the Mesolithic, the date of the Paleolithic–Mesolithic boundary may vary by locality as much as several thousand years. During the Paleolithic period, humans grouped together in small societies such as bands, the Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers, however, due to their nature, surviving artifacts of the Paleolithic era are known as paleoliths. About 50,000 years ago, there was a increase in the diversity of artifacts. For the first time in Africa, bone artifacts and the first art appear in the archaeological record, the first evidence of human fishing is also noted, from artifacts in places such as Blombos cave in South Africa. The new technology generated an explosion of modern humans which is believed to have led to the extinction of the Neanderthals. Humankind gradually evolved from members of the genus Homo—such as Homo habilis. The climate during the Paleolithic consisted of a set of glacial and interglacial periods in which the climate periodically fluctuated between warm and cool temperatures, by c. 50,000 – c. 40,000 BP, the first humans set foot in Australia. By c. 45,000 BP, humans lived at 61°N latitude in Europe, by c. 30,000 BP, Japan was reached, and by c. 27,000 BP humans were present in Siberia, above the Arctic Circle. At the end of the Upper Paleolithic, a group of humans crossed Beringia, the term Paleolithic was coined by archaeologist John Lubbock in 1865. It derives from Greek, παλαιός, palaios, old, and λίθος, lithos, stone, human evolution is the part of biological evolution concerning the emergence of anatomically modern humans as a distinct species. The Paleolithic Period coincides almost exactly with the Pleistocene epoch of geologic time and this epoch experienced important geographic and climatic changes that affected human societies. During the preceding Pliocene, continents had continued to drift from possibly as far as 250 km from their present locations to positions only 70 km from their current location. South America became linked to North America through the Isthmus of Panama, most of Central America formed during the Pliocene to connect the continents of North and South America, allowing fauna from these continents to leave their native habitats and colonize new areas. Africas collision with Asia created the Mediterranean Sea, cutting off the remnants of the Tethys Ocean, climates during the Pliocene became cooler and drier, and seasonal, similar to modern climates. The formation of an Arctic ice cap around 3 million years ago is signaled by a shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic. Mid-latitude glaciation probably began before the end of the epoch, the global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas

Homo antecessor
–
Homo antecessor is an extinct human species dating from 1.2 million to 800,000 years ago, that was discovered by Eudald Carbonell, Juan Luis Arsuaga and J. M. Bermúdez de Castro. The unique mix of modern and primitive traits led the researchers to deem the fossils a new species, H. antecessor, in 1997. Regarding its great age the species must be related to Out of Africa I, author Richard Klein argues that it was a separate species that evolved from H. ergaster. Some scientists consider H. antecessor to be the species as H. heidelbergensis. It’s possible that H. antecessor adults didn’t really look much like H. sapiens at all, the best-preserved fossil is a maxilla that belonged to a ten-year-old individual found in Spain. Based on palaeomagnetic measurements, it is thought to be older than 857–780 ka, in 1994 and 1995,80 fossils of six individuals who may have belonged to the species were found in Atapuerca, Spain. At the site were numerous examples of cuts where the flesh had been flensed from the bones, footprints presumed to be from H. antecessor dating to more than 800,000 years ago have been found at Happisburgh on the coast of Norfolk, England. A2013 DNA analysis from a 400, 000-year-old femur from Spains Sima de los Huesos in the Atapuerca Mountains – the oldest hominin sequence yet published – did not help to overcome contradictions. Results left researchers baffled as the sequence suggests link to mystery population of the Denisovans instead of the Neanderthals as was anticipated. According to the Science X Network the excavation team at the site of Gran Dolina has succeeded to provide conclusive dating of the strata where the Homo antecessor fossils were found. A2014 publication in the Journal of Archaeological Science states that the sediment of Gran Dolina is 900,000 years old, a speciation event could have occurred in Africa/Western Eurasia, originating a new Homo clade, and further, Homo antecessor. Could be a branch of this clade placed at the westernmost region of the Eurasian continent. H. antecessor was about 1. 6–1.8 m tall and their brain sizes were roughly 1, 000–1,150 cm³, smaller than the 1,350 cm³ average of modern humans. Due to fossil scarcity, very little more is known about the physiology of H. antecessor, yet it was likely to have been more robust than H. heidelbergensis. According to Juan Luis Arsuaga, one of the co-directors of the excavation in Burgos, H. antecessor might have been right-handed and this hypothesis is based on tomography techniques. Arsuaga also claims that the range of audition is similar to H. sapiens. Arsuagas team is currently pursuing a DNA map of H. antecessor, based on teeth eruption pattern, the researchers think that H. antecessor had the same development stages as H. sapiens, though probably at a faster pace. Other significant features demonstrated by the species are a protruding occipital bun, a low forehead, some of the remains are almost indistinguishable from the fossil attributable to the 1.5 million year old Turkana Boy, belonging to H. ergaster

Homo heidelbergensis
–
Homo heidelbergensis – also Homo rhodesiensis – is an extinct species of the genus Homo that lived in Africa, Europe and western Asia between 600,000 and 200,000 years ago. The skulls of this species share features with both Homo erectus and anatomically modern Homo sapiens, its brain was nearly as large as that of Homo sapiens. The Sima de los Huesos cave at Atapuerca in northern Spain holds particularly rich layers of deposits that represent an exceptional reserve of data where excavations are still in progress. Neanderthals, Denisovans, and modern humans are all considered to have descended from Homo heidelbergensis that appeared around 700,000 years ago in Africa, fossils have been recovered in Ethiopia, Namibia and South Africa. Between 300,000 and 400,000 years ago a group of Homo heidelbergensis migrated into Europe and West Asia via yet unknown routes, archaeological sites exist in Spain, Italy, France, England, Germany, Hungary and Greece. Another Homo heidelbergensis group ventured eastwards into continental Asia, eventually developing into Denisovans, some researchers suggest that the finds associated to Homo heidelbergensis are mere variants of Homo erectus. Both Homo antecessor and Homo heidelbergensis are likely to have descended from the very similar Homo ergaster from Africa. The anatomy is more primitive than that of Neanderthal, but the harmoniously rounded dental arch. Heidelbergensis from other known human species, the species name heidelbergensis only experienced a renaissance with the many discoveries of the past 30 years and appears now to be recognized by an increasing number of researchers. Any form of segregation is considered arbitrary, which is why these researchers forgo the name H. heidelbergensis altogether. Paleoanthropologists often refer to the surrounding the specimens, their dating and morphology, as “the muddle in the middle. ”The fact that there seem to be no clear transitions makes it difficult to draw up a list of unique characteristics of H. heidelbergensis that distinguishes it from H. erectus. In general, the show a continuation of evolutionary trends that are emerging from around the Lower into Middle Pleistocene. Along with changes in the robustness of cranial and dental features, male H. heidelbergensis averaged about 1.75 m tall and 62 kg. Females averaged 1.57 m and 51 kg, the available space would allow for a far greater flexibility of development and It shows a combination of features, which has been previously found neither on a recent nor a fossil human mandible. The actual proof that we are dealing with human parts here only lies within the nature of the dentition, the completely preserved teeth bear the stamp human as evidence, The canines show no trace of a stronger expression in relation to the other groups of teeth. They suggest a moderate and harmonious co-evolution, as it is the case in recent humans, recent findings in a pit in Atapuerca of 28 human skeletons suggest that H. heidelbergensis might have been the first species of the Homo genus to bury its dead. Steven Mithen believes that H. heidelbergensis, like its descendant H. neanderthalensis, acquired a pre-linguistic system of communication. No forms of art have been uncovered, although red ochre, the morphology of the outer and middle ear suggests they had an auditory sensitivity similar to modern humans and very different from chimpanzees

Neanderthal
–
Neanderthals, or more rarely Neandertals, were a species or subspecies of archaic humans in the genus Homo that became extinct about 40,000 years ago. Neanderthals and modern humans share 99. 7% of their DNA and are closely related. Neanderthals left bones and stone tools in Eurasia, from Western Europe to Central, from the 1950s to the early 1980s, however, Neanderthals were widely considered a subspecies of Homo sapiens and a minority of scholars still hold this view. Several cultural assemblages have been linked to the Neanderthals in Europe, the earliest, the Mousterian stone tool culture, dates to about 160,000 years ago. Late Mousterian artifacts were found in Gorhams Cave on the south-facing coast of Gibraltar, male Neanderthals had cranial capacities averaging 1600 cm3, females 1300 cm3, extending to 1736 cm3 in Amud 1. This is notably larger than the 1250–1400 cm3 typical of modern humans, males stood 164–168 cm and females 152–156 cm tall. Recent studies also show that a few Neanderthals began mating with ancestors of modern humans long before the out of Africa migration of present day non-Africans. Claims that Neanderthals deliberately buried their dead, and if they did, the debate on deliberate Neanderthal burials has been active since the 1908 discovery of the well-preserved Chapelle-aux-Saints 1 skeleton in a small hole in a cave in southwestern France. In 2013, scientists sequenced the genome of a Neanderthal for the first time. The genome was extracted from the bone of a 50. In 2016, elaborate constructions of rings of broken stalagmites made by early Neanderthals around 176,000 years ago were discovered 336 m inside Bruniquel Cave in southwestern France and this would have required a more advanced social structure than previously known for Neanderthals. Thal is a spelling of the German word Tal, which means valley. Nevertheless, Kings name had priority over the proposal put forward in 1866 by Ernst Haeckel, the practice of referring to the Neanderthals and a Neanderthal emerged in the popular literature of the 1920s. The German pronunciation of Neanderthaler or Neandertaler is in the International Phonetic Alphabet, in British English, Neanderthal is pronounced with the /t/ as in German, but different vowels. In laymans American English, Neanderthal is pronounced with a /θ/ and /ɔ/ instead of the longer British /aː/, during the early 20th century the prevailing view was heavily influenced by Arthur Keith and Marcellin Boule, who wrote the first scientific description of a nearly complete Neanderthal skeleton. During the 1930s scholars Ernst Mayr, George Gaylord Simpson and Theodosius Dobzhansky reinterpreted the existing fossil record, Neanderthal man was classified as Homo sapiens neanderthalensis - an early subspecies contrasted with what was now called Homo sapiens sapiens. The obviously unbroken succession of fossil sites of both subspecies in Europe was considered evidence that there was a slow and gradual evolutionary transition from Neanderthals to modern humans, contextual interpretations of similar excavation sites in Asia lead to the hypothesis of multiregional origin of modern man in the 1980s. Current scientific ideas hold that both evolved from a common African ancestor, Homo erectus

World Heritage Site
–
A World Heritage Site is a landmark which has been officially recognized by the United Nations, specifically by the United Nations Educational, Scientific and Cultural Organization. Sites are selected on the basis of having cultural, historical, scientific or some form of significance. UNESCO regards these sites as being important to the interests of humanity. The programme catalogues, names, and conserves sites of outstanding cultural or natural importance to the common culture, under certain conditions, listed sites can obtain funds from the World Heritage Fund. The program was founded with the Convention Concerning the Protection of the Worlds Cultural and Natural Heritage, since then,192 state parties have ratified the convention, making it one of the most adhered to international instruments. As of July 2016,1052 sites are listed,814 cultural,203 natural, in 1959, the governments of Egypt and Sudan requested UNESCO to assist their countries to protect and rescue the endangered monuments and sites. In 1960, the Director-General of UNESCO launched an appeal to the Member States for an International Campaign to Save the Monuments of Nubia, the campaign, which ended in 1980, was considered a success. The project cost $80 million, about $40 million of which was collected from 50 countries, the projects success led to other safeguarding campaigns, saving Venice and its lagoon in Italy, the ruins of Mohenjo-daro in Pakistan, and the Borobodur Temple Compounds in Indonesia. UNESCO then initiated, with the International Council on Monuments and Sites, the United States initiated the idea of cultural conservation with nature conservation. The International Union for Conservation of Nature developed similar proposals in 1968, the Convention came into force on 17 December 1975. As of June 2016, it has been ratified by 192 states, including 188 UN member states plus the Cook Islands, the Holy See, Niue, a country must first list its significant cultural and natural sites, the result is called the Tentative List. A country may not nominate sites that have not been first included on the Tentative List, next, it can place sites selected from that list into a Nomination File. The Nomination File is evaluated by the International Council on Monuments and Sites and these bodies then make their recommendations to the World Heritage Committee. There are ten selection criteria – a site must meet at least one of them to be included on the list, up to 2004, there were six criteria for cultural heritage and four criteria for natural heritage. In 2005, this was modified so there is now only one set of ten criteria. Nominated sites must be of outstanding value and meet at least one of the ten criteria. Thus, the Geneva Convention treaty promulgates, Article 53, PROTECTION OF CULTURAL OBJECTS AND OF PLACES OF WORSHIP. There are 1,052 World Heritage Sites located in 165 States Party, of these,814 are cultural,203 are natural and 35 are mixed properties

Spanish language
–
Spanish —also called Castilian —is a Romance language that originated in the Castile region of Spain, with hundreds of millions of native speakers around the world. It is usually considered the worlds second-most spoken native language after Mandarin Chinese and it is one of the few languages to use inverted question and exclamation marks. Spanish is a part of the Ibero-Romance group of languages, which evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. Beginning in the early 16th century, Spanish was taken to the colonies of the Spanish Empire, most notably to the Americas, as well as territories in Africa, Oceania, around 75% of modern Spanish is derived from Latin. Greek has also contributed substantially to Spanish vocabulary, especially through Latin, Spanish vocabulary has been in contact from an early date with Arabic, having developed during the Al-Andalus era in the Iberian Peninsula. With around 8% of its vocabulary being Arabic in origin, this language is the second most important influence after Latin and it has also been influenced by Basque as well as by neighboring Ibero-Romance languages. It also adopted words from languages such as Gothic language from the Visigoths in which many Spanish names and surnames have a Visigothic origin. Spanish is one of the six languages of the United Nations. It is the language in the world by the number of people who speak it as a mother tongue, after Mandarin Chinese. It is estimated more than 437 million people speak Spanish as a native language. Spanish is the official or national language in Spain, Equatorial Guinea, speakers in the Americas total some 418 million. In the European Union, Spanish is the tongue of 8% of the population. Spanish is the most popular second language learned in the United States, in 2011 it was estimated by the American Community Survey that of the 55 million Hispanic United States residents who are five years of age and over,38 million speak Spanish at home. The Spanish Constitution of 1978 uses the term castellano to define the language of the whole Spanish State in contrast to las demás lenguas españolas. Article III reads as follows, El castellano es la lengua española oficial del Estado, las demás lenguas españolas serán también oficiales en las respectivas Comunidades Autónomas. Castilian is the official Spanish language of the State, the other Spanish languages as well shall be official in their respective Autonomous Communities. The Spanish Royal Academy, on the hand, currently uses the term español in its publications. Two etymologies for español have been suggested, the Spanish Royal Academy Dictionary derives the term from the Provençal word espaignol, and that in turn from the Medieval Latin word Hispaniolus, from—or pertaining to—Hispania

Karst
–
Karst topography is a landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves and it has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes, the English word karst was borrowed from German Karst in the late 19th century. The German word came into use before the 19th century, according to the prevalent interpretation, the term is derived from the German name for the Karst region, a limestone plateau above the city of Trieste in the northern Adriatic. Scholars disagree, however, on whether the German word was borrowed from Slovene, the Slovene common noun kras was first attested in the 18th century, and the adjective form kraški in the 16th century. The Slovene words arose through metathesis from the reconstructed form *korsъ, ultimately, the word is of Mediterranean origin, believed to derive from some Romanized Illyrian base. It has been suggested that the word may derive from the Proto-Indo-European root karra- rock, the name may also be connected to the oronym Karsádios oros cited by Ptolemy, and perhaps also to Latin Carusardius. The development of karst occurs whenever acidic water starts to break down the surface of bedrock near its cracks, as the bedrock continues to degrade, its cracks tend to get bigger. As time goes on, these fractures will become wider, if this underground drainage system does form, it will speed up the development of karst formations there because more water will be able to flow through the region, giving it more erosive power. The carbonic acid that causes karstic features is formed as rain passes through the atmosphere picking up carbon dioxide, once the rain reaches the ground, it may pass through soil that can provide much more CO2 to form a weak carbonic acid solution, which dissolves calcium carbonate. The oxidation of sulfides leading to the formation of acid can also be one of the corrosion factors in karst formation. As oxygen -rich surface waters seep into deep anoxic karst systems, they bring oxygen, sulfuric acid then reacts with calcium carbonate, causing increased erosion within the limestone formation. This chain of reactions is, This reaction chain forms gypsum, the karstification of a landscape may result in a variety of large- or small-scale features both on the surface and beneath. On exposed surfaces, small features may include solution flutes, runnels, limestone pavement, medium-sized surface features may include sinkholes or cenotes, vertical shafts, foibe, disappearing streams, and reappearing springs. Large-scale features may include limestone pavements, poljes, and karst valleys, mature karst landscapes, where more bedrock has been removed than remains, may result in karst towers, or haystack/eggbox landscapes. Beneath the surface, complex underground systems and extensive caves. Some of the most dramatic of these formations can be seen in Thailands Phangnga Bay, calcium carbonate dissolved into water may precipitate out where the water discharges some of its dissolved carbon dioxide. Rivers which emerge from springs may produce tufa terraces, consisting of layers of calcite deposited over extended periods of time, in caves, a variety of features collectively called speleothems are formed by deposition of calcium carbonate and other dissolved minerals

Fossil
–
Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous rock formations and sedimentary layers is known as the fossil record. The study of fossils across geological time, how they were formed, such a preserved specimen is called a fossil if it is older than some minimum age, most often the arbitrary date of 10,000 years. The observation that fossils were associated with certain rock strata led early geologists to recognize a geological timescale in the 19th century. The development of dating techniques in the early 20th century allowed geologists to determine the numerical or absolute age of the various strata. Like extant organisms, fossils vary in size from microscopic, even single bacterial cells one micrometer in diameter, to gigantic, such as dinosaurs, Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces. These types of fossil are called trace fossils, as opposed to body fossils, finally, past life leaves some markers that cannot be seen but can be detected in the form of biochemical signals, these are known as chemofossils or biosignatures. The process of fossilization varies according to type and external conditions. Permineralization is a process of fossilization that occurs when an organism is buried, the empty spaces within an organism become filled with mineral-rich groundwater. Minerals precipitate from the groundwater, occupying the empty spaces and this process can occur in very small spaces, such as within the cell wall of a plant cell. Small scale permineralization can produce very detailed fossils, for permineralization to occur, the organism must become covered by sediment soon after death or soon after the initial decay process. The degree to which the remains are decayed when covered determines the later details of the fossil, some fossils consist only of skeletal remains or teeth, other fossils contain traces of skin, feathers or even soft tissues. This is a form of diagenesis, in some cases the original remains of the organism completely dissolve or are otherwise destroyed. The remaining organism-shaped hole in the rock is called an external mold, if this hole is later filled with other minerals, it is a cast. An endocast or internal mold is formed when sediments or minerals fill the cavity of an organism. This is a form of cast and mold formation. If the chemistry is right, the organism can act as a nucleus for the precipitation of minerals such as siderite, if this happens rapidly before significant decay to the organic tissue, very fine three-dimensional morphological detail can be preserved. Nodules from the Carboniferous Mazon Creek fossil beds of Illinois, USA, are among the best documented examples of such mineralization, replacement occurs when the shell, bone or other tissue is replaced with another mineral

Homo
–
The genus is between 2 and 3 million years old, taken to emerge with the appearance of Homo habilis. It is derived from the genus Australopithecus, which itself had previously split from the lineage of Pan, taxonomically, Homo is the only genus assigned to the subtribe Hominina which, with the subtribes Australopithecina and Panina, comprise the tribe Hominini. All species of the genus Homo plus those species of the australopithecines that arose after the split from Pan are called hominins, Homo erectus appeared about two million years ago in East Africa and, in several early migrations, it spread throughout Africa and Eurasia. It was likely the first hominin to live in a hunter-gatherer society, the subspecies Homo sapiens sapiens or anatomically modern humans emerged about 200,000 years ago in East Africa. DNA analysis provides evidence of interbreeding between archaic and modern humans. See Hominidae for an overview of taxonomy, the Latin noun homō means human being or man in the generic sense of human being, mankind. The binomial name Homo sapiens was coined by Carl Linnaeus, names for other species of the genus were introduced beginning in the second half of the 19th century. Even today, the genus Homo has not been properly defined, since the early human fossil record began to slowly emerge from the earth, the boundaries and definitions of the genus Homo have been poorly defined and constantly in flux. Because there was no reason to think it would ever have any additional members, the discovery of Neanderthal brought the first addition. The genus Homo was given its name to suggest that its member species can be classified as human. Many such names are now dubbed as synonyms with Homo, including Pithecanthropus, Protanthropus, Sinanthropus, Cyphanthropus, Africanthropus, Telanthropus, Atlanthropus, classifying the genus Homo into species and subspecies is subject to incomplete information and remains poorly done. Some recently extinct species in the genus Homo are only recently discovered, john Edward Gray was an early advocate of classifying taxa by designating tribes and families. Several species, including Australopithecus garhi, Australopithecus sediba, Australopithecus africanus and these species have morphological features that align them with Homo, but there is no consensus as to which gave rise to Homo. The advent of Homo was traditionally taken to coincide with the first use of stone tools, the emergence of Homo also coincides roughly with the onset of Quaternary glaciation, the beginning of the current ice age. A fossil mandible fragment dated to 2.8 million years ago which may represent a stage between Australopithecus and Homo was discovered in 2015 in Afar, Ethiopia. Some authors would push the development of Homo past 3 Mya, the most salient physiological development between the earlier australopithecine species and Homo is the increase in cranial capacity, from about 450 cm3 in A. garhi to 600 cm3 in H. habilis. Within the genus Homo, cranial capacity again doubled from H. habilis through Homo ergaster or H. erectus to Homo heidelbergensis by 0.6 million years ago, the cranial capacity of H. heidelbergensis overlaps with the range found in modern humans. Homo erectus has often been assumed to have developed anagenetically from Homo habilis from about 2 million years ago

Western Europe
–
Western Europe, or West Europe, is the region comprising the western part of Europe. Below, some different geographic and geopolitical definitions of the term are outlined, prior to the Roman conquest, a large part of Western Europe had adopted the newly developed La Tène culture. This cultural and linguistic division was reinforced by the later political east-west division of the Roman Empire. The division between these two was enhanced during Late Antiquity and the Middle Ages by a number of events, the Western Roman Empire collapsed, starting the Early Middle Ages. By contrast, the Eastern Roman Empire, mostly known as the Greek or Byzantine Empire, survived, in East Asia, Western Europe was historically known as taixi in China and taisei in Japan, which literally translates as the Far West. The term Far West became synonymous with Western Europe in China during the Ming dynasty, the Italian Jesuit priest Matteo Ricci was one of the first writers in China to use the Far West as an Asian counterpart to the European concept of the Far East. In his writings, Ricci referred to himself as Matteo of the Far West, the term was still in use in the late 19th and early 20th centuries. Post-war Europe would be divided into two spheres, the West, influenced by the United States, and the Eastern Bloc. With the onset of the Cold War, Europe was divided by the Iron Curtain, behind that line lie all the capitals of the ancient states of Central and Eastern Europe. Although some countries were neutral, they were classified according to the nature of their political. This division largely defined the popular perception and understanding of Western Europe, the world changed dramatically with the fall of the Iron Curtain in 1989. The Federal Republic of Germany peacefully absorbed the German Democratic Republic, COMECON and the Warsaw Pact were dissolved, and in 1991, the Soviet Union ceased to exist. Several countries which had part of the Soviet Union regained full independence. Although the term Western Europe was more prominent during the Cold War, it remains much in use, in 1948 the Treaty of Brussels was signed between Belgium, France, Luxembourg, the Netherlands and the United Kingdom. It was further revisited in 1954 at the Paris Conference, when the Western European Union was established and it was declared defunct in 2011, after the Treaty of Lisbon, and the Treaty of Brussels was terminated. When the Western European Union was dissolved, it had 10 member countries, six member countries, five observer countries. The CIA divides Western Europe into two smaller subregions, regional voting blocs were formed in 1961 to encourage voting to various UN bodies from different regional groups. The European Union is an economic and political union of 28 member states that are located primarily in Europe, some Western and Northern European countries of Iceland, Norway, Switzerland and Liechtenstein are members of EFTA, though cooperating to varying degree with the European Union

Lower Paleolithic
–
The Lower Paleolithic is the earliest subdivision of the Paleolithic or Old Stone Age. It spans the time from around 3, the Middle Paleolithic followed the Lower Paleolithic and recorded the appearance of the more advanced prepared-core tool-making technologies such as the Mousterian. Whether the earliest control of fire by hominins dates to the Lower or to the Middle Paleolithic remains an open question. The Lower Paleolithic began with the appearance of the oldest stone tools in the world, roughly 3.3 million ago in eastern Africa, the Gelasian, some 2.5 million years ago, saw the appearance of the Homo genus, possibly developing from australopithecine forebears. Homo habilis is assumed to have lived primarily on scavenging, using tools to cleave meat off carrion or to break bones to extract the marrow, decreasing oceanic evaporation produced a drier climate and the expansion of the savannah at the expense of forests. Reduced availability of fruits stimulated some proto-australopithecines to search out new food sources found in the drier savannah ecology, Homo erectus appeared by about 1.8 million years ago, via the transitional variety Homo ergaster. Homo erectus moved from scavenging to hunting, developing the hunting-gathering lifestyle that would remain dominant throughout the Paleolithic into the Mesolithic, Homo erectus migrated out of Africa and dispersed throughout Eurasia. Stone tools in Malaysia have been dated to be 1.83 million years old, the Peking Man fossil, discovered in 1929, is roughly 700,000 years old. In Europe, the Olduwan tradition split into two parallel traditions, the Clactonian, a tradition, and the Acheulean, a hand-axe tradition. The Levallois technique for knapping flint developed during this time, the carrier species from Africa to Europe was undoubtedly Homo erectus. This type of human is more linked to the flake tradition. Many Mousterian finds in the Middle Paleolithic have been knapped using a Levallois technique, monte Poggiolo, near Forlì, Italy, is the location of an Acheulian littoral handaxe industry dating from 1.8 to 1.1 million years ago. The appearance of Homo heidelbergensis about 600,000 years ago heralds a number of new varieties, such as Homo rhodesiensis. Homo heidelbergensis is a candidate for first developing a form of symbolic language. Whether control of fire and earliest burials date to this period or only appear during the Middle Paleolithic is an open question, the hand-axe tradition originates in the same period. The intermediate may have been Homo heidelbergensis, held responsible for the manufacture of improved Mode 2 Acheulean tool types, in Africa, flakes and axes coexisted in Europe, sometimes at the same site. The axe tradition, however, spread to a different range in the east and it appears in Arabia and India, but more importantly, it does not appear in southeast Asia. Homo sapiens first appear about 200,000 years ago, control of fire by early humans Lomekwi, site of the oldest tools discovered The First People and Culture at Indiana University Bloomington

Homo erectus
–
Homo erectus is an extinct species of hominid that lived throughout most of the Pleistocene geological epoch. Its earliest fossil evidence dates to 1.9 million years ago and extends to 70,000 years ago, or, possibly, as recently as 35,000 years ago. It is generally thought that H. erectus originated in Africa and spread from there, migrating throughout Eurasia as far as Georgia, India, Sri Lanka, China, a new debate appeared in 2013, with the documentation of the Dmanisi skulls.58 million years ago. From there it migrated, in part, by 2, the fossil record shows that its development from about 1.8 mya to one mya was widely distributed, in Africa, the Transcaucasus, Indonesia, and in Vietnam, China, and India. The second hypothesis is that H. erectus evolved in Eurasia and they occupied the Dmanisi site from 1.85 million to 1.77 million years ago, which was about the same time or slightly before their earliest evidence in Africa. There are several proposed explanations of the dispersal of H. erectus georgicus—including whether or not Africa is the source), the Dutch anatomist Eugène Dubois was fascinated by Darwins theory of evolution especially as it applied to humankind. In 1886, he set out for Asia—which then was the region accepted as the cradle of evolution despite Darwins theory of African origin. In 1891, his team discovered a human fossil on the island of Java, the Java fossil from Indonesia aroused much public interest. It was dubbed by the press as Java Man, but few scientists accepted Dubois argument that his fossil was the transitional form—the so-called missing link—between apes. Java Man is now classified as Homo erectus, most of the spectacular discoveries of H. erectus next took place at the Zhoukoudian Project, now known as the Peking Man Site, in Zhoukoudian, China. This site was first discovered by Johan Gunnar Andersson in 1921 and was first excavated in 1921, canadian anatomist Davidson Blacks initial description of a lower molar as belonging to a previously unknown species prompted widely publicized interest. Extensive excavations followed, which altogether uncovered 200 human fossils from more than 40 individuals including five nearly complete skullcaps, german anatomist Franz Weidenreich provided much of the detailed description of this material in several monographs published in the journal Palaeontologica Sinica. Throughout much of the 20th century, anthropologists debated the role of H. erectus in human evolution, early in the century, due in part to the discoveries at Java and Zhoukoudian, it was widely accepted that modern humans first evolved in Asia. From the 1950s forward, numerous finds in East Africa confirmed the hypothesis of an African genesis and it is now generally accepted that H. erectus descended from either, 1) the earliest hominin genera, or 2) the earliest Homo-species. East Africa provided sympatric coexistence for H. erectus and H, in the 1950s, archaeologists John T. Robinson and Robert Broom named Telanthropus capensis, Robinson had discovered a jaw fragment in 1949 in Swartkrans, South Africa. Later, Simonetta proposed to re-designate it to Homo erectus, in 1961, Yves Coppens discovered a skull of Tchadanthropus uxoris, then the earliest fossil human discovered in north Africa. It was reported that the fossil had been so eroded by sand that it mimicked the appearance of an australopith. Although at first considered to be a specimen of H. habilis, T. uxoris is no longer considered a valid taxon, and has been subsumed into H. erectus

UNESCO
–
The United Nations Educational, Scientific and Cultural Organization is a specialized agency of the United Nations based in Paris. It is the heir of the League of Nations International Committee on Intellectual Cooperation, UNESCO has 195 member states and nine associate members. Most of its offices are cluster offices covering three or more countries, national and regional offices also exist. UNESCO pursues its objectives through five major programs, education, natural sciences, social/human sciences, culture and it is also a member of the United Nations Development Group. UNESCO and its mandate for international cooperation can be traced back to a League of Nations resolution on 21 September 1921, on 18 December 1925, the International Bureau of Education began work as a non-governmental organization in the service of international educational development. However, the work of predecessor organizations was largely interrupted by the onset of World War II. On 30 October 1943, the necessity for an organization was expressed in the Moscow Declaration, agreed upon by China, the United Kingdom, the United States. This was followed by the Dumbarton Oaks Conference proposals of 9 October 1944, a prominent figure in the initiative for UNESCO was Rab Butler, the Minister of Education for the United Kingdom. At the ECO/CONF, the Constitution of UNESCO was introduced and signed by 37 countries, the Preparatory Commission operated between 16 November 1945, and 4 November 1946—the date when UNESCOs Constitution came into force with the deposit of the twentieth ratification by a member state. The first General Conference took place between 19 November to 10 December 1946, and elected Dr. Julian Huxley to Director-General and this change in governance distinguished UNESCO from its predecessor, the CICI, in how member states would work together in the organizations fields of competence. In 1956, the Republic of South Africa withdrew from UNESCO claiming that some of the organizations publications amounted to interference in the racial problems. South Africa rejoined the organization in 1994 under the leadership of Nelson Mandela, UNESCOs early work in the field of education included the pilot project on fundamental education in the Marbial Valley, Haiti, started in 1947. This project was followed by missions to other countries, including, for example. In 1948, UNESCO recommended that Member States should make free primary education compulsory, in 1990, the World Conference on Education for All, in Jomtien, Thailand, launched a global movement to provide basic education for all children, youths and adults. Ten years later, the 2000 World Education Forum held in Dakar, Senegal, UNESCOs early activities in culture included, for example, the Nubia Campaign, launched in 1960. The purpose of the campaign was to move the Great Temple of Abu Simbel to keep it from being swamped by the Nile after construction of the Aswan Dam, during the 20-year campaign,22 monuments and architectural complexes were relocated. This was the first and largest in a series of campaigns including Mohenjo-daro, Fes, Kathmandu, Borobudur, the organizations work on heritage led to the adoption, in 1972, of the Convention concerning the Protection of the World Cultural and Natural Heritage. The World Heritage Committee was established in 1976 and the first sites inscribed on the World Heritage List in 1978, since then important legal instruments on cultural heritage and diversity have been adopted by UNESCO member states in 2003 and 2005

Altitudinal zonation
–
Altitudinal zonation in mountainous regions describes the natural layering of ecosystems that occurs at distinct altitudes due to varying environmental conditions. Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, Altitudinal zonation was first hypothesized by geographer Alexander von Humboldt who noticed that temperature drops with increasing elevation. Zonation also occurs in intertidal and marine environments, as well as on shorelines, scientist C. Hart Merriam observed that changes in vegetation and animals in altitudinal zones map onto changes expected with increased latitude in his concept of life zones. Today, altitudinal zonation represents a concept in mountain research. The cause of zonation is complex, due to possible interactions. Careful measurements and statistical tests are required prove the existence of discrete communities along an elevation gradient, decreasing air temperature usually coincides with increasing elevation, which directly influences the length the growing season at different altitudes of the mountain. For mountains located in deserts, extreme temperatures also limit the ability of large deciduous or coniferous trees to grow near the base of mountains. In addition, plants can be sensitive to soil temperatures. The most important variable is precipitation at various altitudes, as warm, moist air rises up the windward side of a mountain, the air temperature cools and loses its capacity to hold moisture. Thus, the greatest amount of rainfall is expected at mid-altitudes, above a certain elevation the rising air becomes too dry and cold, and thus discourages tree growth. Although rainfall may not be a significant factors for some mountains, both overall levels of precipitation and humidity influence soil moisture as well. One of the most important factors that controls the lower boundary of the encinal or forest level is the ratio of evaporation to soil moisture, the nutrient content of soils at different altitudes further complicates the demarcation of altitudinal zones. Soils with higher nutrient content, due to higher decomposition rates or greater weathering of rocks, better support larger trees, the altitude of better soils varies with the particular mountain being studied. For example, for mountains found in the rain forest regions. At this latitude more acidic, humose soils exist at elevations in the montane or subapline levels. In a different example, weathering is hampered by low temperatures at higher elevations in the Rocky Mountain of the western United States, in addition to physical forces, biological forces may also produce zonation. For example, a competitor can force weaker competitors to higher or lower positions on the elevation gradient. The importance of competition is difficult to assess without experiments, which are expensive, however, there is an accumulating body of evidence that competitively dominant plants may seize the preferred locations

Douro
–
The Douro is one of the major rivers of the Iberian Peninsula, flowing from its source near Duruelo de la Sierra in Soria Province across northern-central Spain and Portugal to its outlet at Porto. The Latinized name Durius, likely came from the Celtic tribes that inhabited the area before Roman times, in modern Welsh, dŵr is water, as well as dour in modern Breton with cognate dobhar in Irish. In Roman times, the river was personified as a god, the Douro vinhateiro, an area of the Douro Valley in Portugal long devoted to vineyards, has been designated by UNESCO as a World Heritage Site. Traditionally, the wine was taken down river in boats called rabelos, to be stored in barrels in cellars in Vila Nova de Gaia. In the 1950s and 1960s, dams were built along the river, now Port wine is transported in tanker trucks. In 1998, Portugal and Spain signed the Albufeira Convention, an agreement on the sharing of trans-boundary rivers to include the Douro, Tagus, the convention superseded an original agreement on the Douro, signed in 1927, that was expanded in 1964 and 1968 to include tributaries. It is the third-longest river in the Iberian Peninsula after the Tagus and its total length is 897 kilometres, of which only sections of the Portuguese extension below the fall line are navigable, by light rivercraft. In this region, there are few tributaries of the Douro, the most important are the Pisuerga, passing through Valladolid, and the Esla, which passes through Zamora. This region is generally semi-arid plains, with wheat and in places, especially near Aranda de Duero, with vineyards. Sheep rearing is still important. For 112 kilometres, the forms part of the national border line between Spain and Portugal, in a region of narrow canyons. It formed a barrier to invasions, creating a cultural/linguistic divide. In these isolated areas, in which the Aldeadávila Dam impounds the river, there are protected areas, the International Douro Natural Park and the Arribes del Duero Natural Park. The Douro fully enters Portuguese territory just after the confluence with the Águeda River, once the Douro enters Portugal, except for Porto and Vila Nova de Gaia at the river mouth, the only population centres of any note are Foz do Tua, Pinhão and Peso da Régua. Tributaries here are small, merging into the Douro along the canyons, the most important are Côa, Tua, Sabor, Corgo, Tavora, Paiva, Tâmega, none of these small, fast-flowing rivers is navigable. The most populous cities along the Douro River are Valladolid and Zamora in Spain, the latter two are located at the mouth of the Douro at the Atlantic Ocean. In Portugal, the Douro flows through the districts of Bragança, Guarda, Viseu, Vila Real, Aveiro, Porto is the main hub city in northern Portugal. Its historic centre has designated as a UNESCO World Heritage Site because of its significant architecture

Cantabrian Mountains
–
The Cantabrian Mountains or Cantabrian Range are one of the main systems of mountain ranges in Spain. They stretch for over 300 km across northern Spain, from the limit of the Pyrenees to the Galician Massif in Galicia. Their easternmost end meets the Sistema Ibérico and these mountains are a distinct physiographic province of the larger Alpine System physiographic division. The Cantabrian Mountains offer a range of trails for hiking. Skiing is possible in the ski resorts of Alto Campoo, Valgrande-Pajares, the Cantabrian Mountains stretch east-west, nearly parallel to the sea, as far as the pass of Leitariegos, also extending south between León and Galicia. The ranges western boundary is marked by the valley of the river Miño, by the lower Sil, which flows into the Miño, and by the Cabrera River, Cantabrian mountains reach its south-western limit in Portugal. In some parts the coastal range rises sheer above the sea, the descent from the southern range to the high plateaux of Castile is more gradual, and several large rivers, notably the Ebro, rise here and flow to the south or west. The breadth of the Cantabrian chain, with all its ramifications, increases from about 60 mi, many peaks are over 6000 ft high, but the greatest altitudes are attained in the central ridges on the borders of León, Asturias, Palencia and Cantabria. A conspicuous feature of the chain, as of the adjacent tableland, is the number of its parameras, the Cantabrian Mountains make a sharp divide between Green Spain to the north, and the dry central plateau. The north facing slopes receive heavy rainfall from the Bay of Biscay. The Cantabrian Range has three distinct sections from west to east, The Asturian Massif and its foothills. Geologically it is a prolongation of the Galician Massif with Paleozoic folds. It is cut by deep east-west oriented canyons such as the Cares River valley, highest point Torre de Cerredo 2,648 m. They are composed of Carboniferous limestone and marl, the Paramo de Masa and La Lora grasslands are located in the south crossed by the Rudrón Valley. Other animals associated with the range include the Iberian wolf and the rebeco, some of the sites are included in the European Unions Natura 2000 network and Special Protection Areas for the Conservation of Wild Birds

Ebro
–
The Ebro or Ebre is one of the most important rivers on the Iberian Peninsula. It is the second longest river in the Iberian peninsula after the Tagus, the source of the river Ebro is in Fontibre, from the Latin words Fontes Iberis, source of the Ebro. Close by is the big artificial lake Embalse del Ebro created by the damming of the river, the upper Ebro rushes through rocky gorges in Burgos Province. Karst geological processes shaped the landscape of layers of carbonate rock of extensive limestone bedrock formed in an ancient seabed. Aragonite, a named for Aragon, attests to the fact that carbonates are abundant in the central Ebro Valley. The valley expands and the Ebros flow then becomes slower as its volume increases. There, larger tributaries flowing from the Central Pyrenees and the Iberian System discharge large amounts of water, as it flows through Zaragoza the Ebro, is already a sizeable river. There, the Basilica of Our Lady of the Pillar stands next to the Ebro, the soils in most of the valley are primarily poor soils, calcareous, pebbly, stony, and sometimes salted with saltwater endorheic lagoons. The semi-arid interior of the Ebro Valley has either drought summers and it is covered with chaparral vegetation. Summers are hot and winters are cold, the dry summer season has temperatures of more than 35 °C, occasionally reaching over 40 °C. In winter, the temperatures drop below 0 °C. In some areas the vegetation depends heavily on moisture produced by condensation fogs and it is a continental Mediterranean climate with extreme temperatures. There are many ground frosts on clear nights, and sporadic snowfalls, the biomes are diverse in these Mediterranean climate zones, Mediterranean forests, woodlands, and scrub. Hinterlands are particularly distinctive on account of extensive sclerophyll shrublands known as maquis, the dominant species are Quercus coccifera and Quercus ilex. These trees form monospecific communities or communities integrated with Pinus, Mediterranean buckthorns, Myrtus, Chamaerops humilis, junipers, Pistacia, Rosmarinus, Thymus, etc. The mountain vegetation is mostly coniferous forests that are drought adapted and their presence is related to the marine origin of the Ebro valley and the extensive marine deposits in the same area. After reaching Catalonia, the Ebro Valley narrows, and the river becomes constrained by mountain ranges, massive dams have been built in this area, such as the dams at Mequinenza, Riba-roja, Flix. In the final section of its course the river bends southwards, the massive calcareous cliffs of the Serra de Cardó range constrain the river during this last stretch, separating the Ebro Valley from the Mediterranean coastal area

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
22.
Ecotone
–
An ecotone is a transition area between two biomes. It is where two communities meet and integrate and it may be narrow or wide, and it may be local or regional. An ecotone may appear on the ground as a blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line. The word ecotone was coined from a combination of eco plus -tone, from the Greek tonos or tension – in other words, there are several distinguishing features of an ecotone. First, an ecotone can have a sharp transition, with a distinct line between two communities. For example, a change in colors of grasses or plant life can indicate an ecotone, second, a change in physiognomy can be a key indicator. Scientists look at color variations and changes in plant height, third, a change of species can signal an ecotone. There will be specific organisms on one side of an ecotone or the other, other factors can illustrate or obscure an ecotone, for example, migration and the establishment of new plants. These are known as spatial mass effects, which are noticeable because some organisms will not be able to form self-sustaining populations if they cross the ecotone. Lastly, the abundance of species in an ecotone can reveal the type of biome or efficiency of the two communities sharing space. Because an ecotone is the zone in two communities integrate, many different forms of life have to live together and compete for space. Therefore, an ecotone can create a diverse ecosystem, changes in the physical environment may produce a sharp boundary, as in the example of the interface between areas of forest and cleared land. Elsewhere, a more gradually blended interface area will be found, mountain ranges often create such ecotones, due to the wide variety of climatic conditions experienced on their slopes. They may also provide a boundary between species due to the nature of their terrain. Mont Ventoux in France is an example, marking the boundary between the flora and fauna of northern and southern France. Plants in competition extend themselves on one side of the ecotone as far as their ability to maintain themselves allows, beyond this competitors of the adjacent community take over. As a result, the ecotone represents a shift in dominance, ecotones are particularly significant for mobile animals, as they can exploit more than one set of habitats within a short distance. The ecotone contains not only common to the communities on both sides, it may also include a number of highly adaptable species that tend to colonize such transitional areas
23.
Ecosystem
–
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles, as ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces. Energy, water, nitrogen and soil minerals are other essential components of an ecosystem. The energy that flows through ecosystems is obtained primarily from the sun and it generally enters the system through photosynthesis, a process that also captures carbon from the atmosphere. By feeding on plants and on one another, animals play an important role in the movement of matter and they also influence the quantity of plant and microbial biomass present. Ecosystems are controlled both by external and internal factors, other external factors include time and potential biota. Ecosystems are dynamic entities—invariably, they are subject to disturbances and are in the process of recovering from some past disturbance. Ecosystems in similar environments that are located in different parts of the world can have different characteristics simply because they contain different species. The introduction of species can cause substantial shifts in ecosystem function. Internal factors not only control ecosystem processes but are controlled by them and are often subject to feedback loops. Other internal factors include disturbance, succession and the types of species present, although humans exist and operate within ecosystems, their cumulative effects are large enough to influence external factors like climate. Biodiversity affects ecosystem function, as do the processes of disturbance, classifying ecosystems into ecologically homogeneous units is an important step towards effective ecosystem management, but there is no single, agreed-upon way to do this. The term ecosystem was first used in 1935 in a publication by British ecologist Arthur Tansley, Tansley devised the concept to draw attention to the importance of transfers of materials between organisms and their environment. He later refined the term, describing it as The whole system, including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment. Tansley regarded ecosystems not simply as natural units, but as mental isolates, Tansley later defined the spatial extent of ecosystems using the term ecotope. G. Raymond Lindeman took these ideas one step further to suggest that the flow of energy through a lake was the driver of the ecosystem. Most mineral nutrients, on the hand, are recycled within ecosystems. Ecosystems are controlled both by external and internal factors, external factors, also called state factors, control the overall structure of an ecosystem and the way things work within it, but are not themselves influenced by the ecosystem

Causeway
–
In modern usage, a causeway is a road or railway on top an embankment usually across a broad body of water or wetland. When first used, the word appeared in a such as causey way making clear its derivation from the earlier form causey. This word seems to have come from the source by two different routes. It derives ultimately, from the Latin for heel, calx, anciently, the construction was trodden down, one layer at a time, often by slaves or flocks of sheep. Today, this work is done by machines, the same technique would have been used for road embankments, raised river banks, sea banks and fortification earthworks. The second derivation route is simply the hard, trodden surface of a path, the name by this route came to be applied to a firmly-surfaced road. It is now little-used except in dialect and in the names of roads which were notable for their solidly-made surface. The 1911 Encyclopædia Britannica states causey, a mound or dam, which is derived, through the Norman-French caucie, from the late Latin via calciata, a road stamped firm with the feet. The word is comparable in both meanings with the French chaussée, from a form of which it reached English by way of Norman French. The French adjective, chaussée, carries the meaning of having given a hardened surface. As a noun chaussée is used on the one hand for a metalled carriageway, other languages have a noun with similar dual meaning. The Welsh is relevant here, as it also has a verb, sarnu, a transport corridor that is carried instead on a series of arches, perhaps approaching a bridge, is a viaduct. In the U. S. a short stretch of viaduct is called an overpass, some low causeways across shore waters become inaccessible when covered at high tide. The modern embankment may be constructed within a cofferdam, two parallel steel sheet pile or concrete retaining walls, anchored to each other with steel cables or rods. This construction may also serve as a dyke that keeps two bodies of water apart, such as bodies with a different water level on each side, or with water on one side. This may also be the purpose of a structure, the road providing a hardened crest for the dike. It also provides access for maintenance as well perhaps, as a public service, notable causeways include those that connect Singapore and Malaysia, Bahrain and Saudi Arabia and Venice to the mainland, all of which carry roadways and railways. In the Netherlands there are a number of prominent dykes which also double as causeways, including the Afsluitdijk, Brouwersdam, in Louisiana, two very long bridges, called the Lake Pontchartrain Causeway, stretch across Lake Pontchartrain for almost 38 km, making them the worlds longest bridges

Ancient Rome
–
In its many centuries of existence, the Roman state evolved from a monarchy to a classical republic and then to an increasingly autocratic empire. Through conquest and assimilation, it came to dominate the Mediterranean region and then Western Europe, Asia Minor, North Africa and it is often grouped into classical antiquity together with ancient Greece, and their similar cultures and societies are known as the Greco-Roman world. Ancient Roman civilisation has contributed to modern government, law, politics, engineering, art, literature, architecture, technology, warfare, religion, language and society. Rome professionalised and expanded its military and created a system of government called res publica, the inspiration for modern republics such as the United States and France. By the end of the Republic, Rome had conquered the lands around the Mediterranean and beyond, its domain extended from the Atlantic to Arabia, the Roman Empire emerged with the end of the Republic and the dictatorship of Augustus Caesar. 721 years of Roman-Persian Wars started in 92 BC with their first war against Parthia and it would become the longest conflict in human history, and have major lasting effects and consequences for both empires. Under Trajan, the Empire reached its territorial peak, Republican mores and traditions started to decline during the imperial period, with civil wars becoming a prelude common to the rise of a new emperor. Splinter states, such as the Palmyrene Empire, would divide the Empire during the crisis of the 3rd century. Plagued by internal instability and attacked by various migrating peoples, the part of the empire broke up into independent kingdoms in the 5th century. This splintering is a landmark historians use to divide the ancient period of history from the pre-medieval Dark Ages of Europe. King Numitor was deposed from his throne by his brother, Amulius, while Numitors daughter, Rhea Silvia, because Rhea Silvia was raped and impregnated by Mars, the Roman god of war, the twins were considered half-divine. The new king, Amulius, feared Romulus and Remus would take back the throne, a she-wolf saved and raised them, and when they were old enough, they returned the throne of Alba Longa to Numitor. Romulus became the source of the citys name, in order to attract people to the city, Rome became a sanctuary for the indigent, exiled, and unwanted. This caused a problem for Rome, which had a large workforce but was bereft of women, Romulus traveled to the neighboring towns and tribes and attempted to secure marriage rights, but as Rome was so full of undesirables they all refused. Legend says that the Latins invited the Sabines to a festival and stole their unmarried maidens, leading to the integration of the Latins, after a long time in rough seas, they landed at the banks of the Tiber River. Not long after they landed, the men wanted to take to the sea again, one woman, named Roma, suggested that the women burn the ships out at sea to prevent them from leaving. At first, the men were angry with Roma, but they realized that they were in the ideal place to settle. They named the settlement after the woman who torched their ships, the Roman poet Virgil recounted this legend in his classical epic poem the Aeneid

Pilgrimage
–
A pilgrimage is a journey or search of moral or spiritual significance. Typically, it is a journey to a shrine or other location of importance to a persons beliefs and faith, a person who makes such a journey is called a pilgrim. As a common experience, pilgrimage has been proposed as a Jungian archetype by Wallace Clift. The Holy Land acts as a point for the pilgrimages of the Abrahamic religions of Judaism, Christianity. Baháulláh decreed pilgrimage to two places in the Kitáb-i-Aqdas, the House of Baháulláh in Baghdad, Iraq, and the House of the Báb in Shiraz, later, Abdul-Bahá designated the Shrine of Baháulláh at Bahji, Israel as a site of pilgrimage. Other pilgrimage places in India and Nepal connected to the life of Gautama Buddha are, Savatthi, Pataliputta, Nalanda, Gaya, Vesali, Sankasia, Kapilavastu, Kosambi, Rajagaha, Varanasi, other famous places for Buddhist pilgrimage include, India, Sanchi, Ellora, Ajanta. Thailand, Sukhothai, Ayutthaya, Wat Phra Kaew, Wat Doi Suthep, tibet, Lhasa, Mount Kailash, Lake Nam-tso. Sri Lanka, Polonnaruwa, Temple of the Tooth, Anuradhapura, malaysia, Kek Lok Si, Cheng Hoon Teng, Maha Vihara Myanmar, Bagan, Sagaing Hill. The Four Sacred Mountains Japan, Shikoku Pilgrimage,88 Temple pilgrimage in the Shikoku island, Japan 100 Kannon, pilgrimage composed of the Saigoku, Bandō and Chichibu pilgrimages. Saigoku 33 Kannon, pilgrimage in the Kansai region, Bandō33 Kannon, pilgrimage in the Kantō region. Chichibu 34 Kannon, pilgrimage in Saitama Prefecture, Chūgoku 33 Kannon, pilgrimage in the Chūgoku region. Christian pilgrimage was first made to sites connected with the birth, life, pilgrimages were, and are, also made to Rome and other sites associated with the apostles, saints and Christian martyrs, as well as to places where there have been apparitions of the Virgin Mary. A popular pilgrimage journey is along the Way of St. James to the Santiago de Compostela Cathedral, in Galicia, Spain, chaucers The Canterbury Tales recounts tales told by Christian pilgrims on their way to Canterbury Cathedral and the shrine of Thomas Becket. According to Karel Werners Popular Dictionary of Hinduism, most Hindu places of pilgrimage are associated with events from the lives of various gods. Almost any place can become a focus for pilgrimage, but in most cases they are sacred cities, rivers, lakes, Hindus are encouraged to undertake pilgrimages during their lifetime, though this practice is not considered absolutely mandatory. Most Hindus visit sites within their region or locale, Kumbh Mela, Kumbh Mela is one of the largest gatherings of humans in the world. The location is rotated among Allahabad, Haridwar, Nashik, Char Dham, The four holy sites Puri, Rameswaram, Dwarka, and Badrinath compose the Char Dham pilgrimage circuit. Kanwar Pilgrimage, The Kanwar is Indias largest annual religious pilgrimage, as part of this phenomenon, millions of participants gather sacred water from the Ganga and carry it across hundreds of miles to dispense as offerings in Śiva shrines

Camino de Santiago
–
Many follow its routes as a form of spiritual path or retreat for their spiritual growth. It is also popular hiking and cycling enthusiasts as well as organized tours. The Way of St. Legend holds that St. Jamess remains were carried by boat from Jerusalem to northern Spain, the Way can take one of dozens of pilgrimage routes to Santiago de Compostela. Traditionally, as with most pilgrimages, the Way of Saint James began at ones home, however, a few of the routes are considered main ones. During the Middle Ages, the route was highly travelled, however, the Black Death, the Protestant Reformation, and political unrest in 16th century Europe led to its decline. By the 1980s, only a few pilgrims per year arrived in Santiago, later, the route attracted a growing number of modern-day pilgrims from around the globe. In October 1987, the route was declared the first European Cultural Route by the Council of Europe, whenever St. Jamess Day falls on a Sunday, the cathedral declares a Holy or Jubilee Year. Depending on leap years, Holy Years occur in 5,6, the most recent were 1982,1993,1999,2004, and 2010. The next will be 2021,2027, and 2032, the pilgrimage to Santiago has never ceased from the time of the discovery of St. Jamess remains, though there have been years of fewer pilgrims, particularly during European wars. The main pilgrimage route to Santiago follows an earlier Roman trade route, at night, the Milky Way overhead seems to point the way, so the route acquired the nickname Voie lactée – the Milky Way in French. The scallop shell, often found on the shores in Galicia, has long been the symbol of the Camino de Santiago. Over the centuries the scallop shell has taken on mythical, metaphorical and practical meanings, two versions of the most common myth about the origin of the symbol concern the death of Saint James, who was martyred by beheading in Jerusalem in 44 AD. According to Spanish legends, he had spent time preaching the gospel in Spain, version 1, After Jamess death, his disciples shipped his body to the Iberian Peninsula to be buried in what is now Santiago. Off the coast of Spain, a storm hit the ship. After some time, however, it washed ashore undamaged, covered in scallops, version 2, After Jamess death his body was transported by a ship piloted by an angel, back to the Iberian Peninsula to be buried in what is now Santiago. As the ship approached land, a wedding was taking place on shore, the young groom was on horseback, and on seeing the ship approaching, his horse got spooked, and horse and rider plunged into the sea. Through miraculous intervention, the horse and rider emerged from the water alive, the scallop shell also acts as a metaphor. The grooves in the shell, which meet at a point, represent the various routes pilgrims traveled, eventually arriving at a single destination

N-I
–
The N-I was the former main road from Madrid to France in Spain. The majority has now replaced by the Autovía A-1 and Autopista AP-1. Autovía A-1 starts at Madrid then goes to Burgos, N-I then runs parallel to AP-1 to Miranda de Ebro. It becomes again A-1 and goes via then goes via Vitoria, Altsasu, Beasain, Tolosa, Donostia and Irun

Drainage divide
–
A drainage divide, water divide, divide, ridgeline, watershed, water parting, is the line that separates neighbouring drainage basins. In hilly country, the divide lies along topographical ridges, and may be in the form of a range of hills or mountains. In flat country—especially where the ground is marshy—the divide may be harder to discern, a valley floor divide is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Settlements are often built on valley-floor divides in the Alps, examples are Eben im Pongau, Kirchberg in Tirol and Waidring. Extremely low divides with heights of less than two metres are found on the North German Plain within the Urstromtäler, for example, between Havel and Finow in the Eberswalde Urstromtal. In marsh deltas such as the Okavango, the largest drainage area on earth, or in large areas, such as the Finnish Lakeland. Another case is bifurcation, where the watershed is effectively in the river bed, in pre-industrial times, water divides were crossed at portages. Later, canals connected adjoining drainage basins, a key problem in such canals is ensuring a sufficient water supply, category, Drainage basins List of watershed topics European watershed Scottish watershed River source

Rail transport
–
Rail transport is a means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks. It is also referred to as train transport. In contrast to road transport, where vehicles run on a flat surface. Tracks usually consist of rails, installed on ties and ballast, on which the rolling stock, usually fitted with metal wheels. Other variations are possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a transport system generally encounters lower frictional resistance than road vehicles, so passenger. The operation is carried out by a company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electric power from a railway system or produce their own power. Most tracks are accompanied by a signalling system, Railways are a safe land transport system when compared to other forms of transport. The oldest, man-hauled railways date back to the 6th century BC, with Periander, one of the Seven Sages of Greece, Rail transport blossomed after the British development of the steam locomotive as a viable source of power in the 19th centuries. With steam engines, one could construct mainline railways, which were a key component of the Industrial Revolution, also, railways reduced the costs of shipping, and allowed for fewer lost goods, compared with water transport, which faced occasional sinking of ships. The change from canals to railways allowed for markets in which prices varied very little from city to city. In the 1880s, electrified trains were introduced, and also the first tramways, starting during the 1940s, the non-electrified railways in most countries had their steam locomotives replaced by diesel-electric locomotives, with the process being almost complete by 2000. During the 1960s, electrified high-speed railway systems were introduced in Japan, other forms of guided ground transport outside the traditional railway definitions, such as monorail or maglev, have been tried but have seen limited use. The history of the growth, decline and restoration to use of transport can be divided up into several discrete periods defined by the principal means of motive power used. The earliest evidence of a railway was a 6-kilometre Diolkos wagonway, trucks pushed by slaves ran in grooves in limestone, which provided the track element. The Diolkos operated for over 600 years, Railways began reappearing in Europe after the Dark Ages. The earliest known record of a railway in Europe from this period is a window in the Minster of Freiburg im Breisgau in Germany

Bronze Age
–
The Bronze Age is a historical period characterized by the use of bronze, proto-writing, and other early features of urban civilization. The Bronze Age is the principal period of the three-age Stone-Bronze-Iron system, as proposed in modern times by Christian Jürgensen Thomsen. An ancient civilization is defined to be in the Bronze Age either by smelting its own copper and alloying with tin, arsenic, or other metals, or by trading for bronze from production areas elsewhere. Copper-tin ores are rare, as reflected in the fact there were no tin bronzes in Western Asia before trading in bronze began in the third millennium BC. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition, although the Iron Age generally followed the Bronze Age, in some areas, the Iron Age intruded directly on the Neolithic. Bronze Age cultures differed in their development of the first writing, according to archaeological evidence, cultures in Mesopotamia and Egypt developed the earliest viable writing systems. The overall period is characterized by use of bronze, though the place and time of the introduction. Human-made tin bronze technology requires set production techniques, tin must be mined and smelted separately, then added to molten copper to make bronze alloy. The Bronze Age was a time of use of metals. The dating of the foil has been disputed, the Bronze Age in the ancient Near East began with the rise of Sumer in the 4th millennium BC. Societies in the region laid the foundations for astronomy and mathematics, the usual tripartite division into an Early, Middle and Late Bronze Age is not used. Instead, a division based on art-historical and historical characteristics is more common. The cities of the Ancient Near East housed several tens of thousands of people, ur in the Middle Bronze Age and Babylon in the Late Bronze Age similarly had large populations. The earliest mention of Babylonia appears on a tablet from the reign of Sargon of Akkad in the 23rd century BC, the Amorite dynasty established the city-state of Babylon in the 19th century BC. Over 100 years later, it took over the other city-states. Babylonia adopted the written Semitic Akkadian language for official use, by that time, the Sumerian language was no longer spoken, but was still in religious use. Elam was an ancient civilization located to the east of Mesopotamia, in the Old Elamite period, Elam consisted of kingdoms on the Iranian plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. Its culture played a role in the Gutian Empire and especially during the Achaemenid dynasty that succeeded it

Anatomically modern human
–
Anatomically modern humans evolved from archaic humans in the Middle Paleolithic, about 200,000 years ago. The emergence of modern human marks the dawn of the species Homo sapiens. Other fossils include the proposed Homo sapiens idaltu from Herto in Ethiopia that are almost 160,000 years old and the Skhul hominids from Israel, which are 90,000 years old. The oldest human remains from which an entire genome has been extracted belongs to Ust-Ishim man, however, it can and has been argued that Homo sapiens have been fully capable of modern behavior from the time they first evolved. The binomial name for the species of the human population is Homo sapiens. The species is taken to have emerged from a predecessor within the Homo genus around 200,000 years ago. Generally, modern humans are more lightly built than archaic humans from which they have evolved, Humans are a highly variable species, modern humans can show remarkably robust traits, and early modern humans even more so. Despite this, modern humans differ from archaic people in a range of anatomical details, the cranium lacks a pronounced occipital bun in the neck, a bulge that anchored considerable neck muscles in Neanderthals. Modern humans, even the ones, generally have a larger fore-brain than the archaic people. This will usually give a higher forehead, and reduced brow ridge and this splits the ridge into a central part and two distal parts. In current humans, often only the section of the ridge is preserved. This contrasts with archaic humans, where the ridge is pronounced. Modern humans commonly have a steep, even vertical forehead whereas their predecessors had foreheads that sloped strongly backwards, according to Desmond Morris, the vertical forehead in humans not only houses larger brains, but plays an important role in human communication through eyebrow movements and forehead skin wrinkling. Compared to archaic people, anatomically modern humans have smaller, differently shaped teeth and this results in a smaller, more receded dentary, making the rest of the jaw-line stand out, giving an often quite prominent chin. The central part of the forming the chin carries a triangularly shaped area forming the apex of the chin called the mental trigon. Particularly in living population, the use of fire and tools require fewer jaw muscles, giving slender, compared to archaic people, modern humans have smaller, lower faces. The body skeletons of even the earliest and most robustly built modern humans were less robust than those of Neanderthals, particularly regarding the long bones of the limbs, the distal bones are nearly the same size or slightly shorter than the proximal bones. In ancient people, particularly Neanderthals, the bones were shorter

Juan Luis Arsuaga

As a child he already showed a great interest in prehistory after reading The Quest for Fire and visiting a dig in nearby Bilbao. The finds at Atapuerca have shed new light on the first humans in Europe and this contrasts with the secretive atmosphere surrounding the digs to near Orce, in southern Spain, which has yielded tools indicating human presence that predate the finds at Atapuerca. In 2013, Arsuaga co-authored a paper which reported the finding of the oldest human DNA ever, the mitochondrial DNA that stemmed from a fossil found in a cave in Sima de los Huesos had similarities to mitochondrial genomes previously found in the extinct Denisovans in Siberia. He has been a lecturer at the universities of London, Cambridge, Zurich, Rome, Arizona, Philadelphia, Berkeley, New York, Tel Aviv, among others. He authored and/or published several publications in Nature, Science, Journal of Archaeological Science, American Journal of Physical Anthropology

Mandible
–
The mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the face. It forms the lower jaw and holds the teeth in place. The mandible sits beneath the maxilla, the bone is formed from a fusion of left and right processes, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, the body of the mandible is curved somewhat like a horseshoe and has two surfaces and two borders. From the outside, the mandible is marked in the midline by a faint ridge and this ridge divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle. On either side of the symphysis, just below the teeth, is a depression, the incisive fossa, which gives origin to the mentalis. Below the second premolar tooth, on side, midway between the upper and lower borders of the body, is the mental foramen, for the passage of the mental vessels. From the inside, the mandible appears concave, near the lower part of the symphysis is a pair of laterally placed spines, termed the mental spines, which give origin to the genioglossus. Immediately below these is a pair of spines, or more frequently a median ridge or impression. In some cases the mental spines are fused to form a single eminence, in others they are absent, above the mental spines a median foramen and furrow are sometimes seen, they mark the line of union of the halves of the bone. Below the mental spines, on side of the middle line, is an oval depression for the attachment of the anterior belly of the digastric. Above the anterior part of line is a smooth triangular area against which the sublingual gland rests, and below the hinder part. To the outer lip of the border, on either side. The ramus of the mandible has four sides, two surfaces, four borders, and two processes. On the outside, the ramus is flat and marked by oblique ridges at its lower part, on the inside, the mandible presents about its center the oblique mandibular foramen, for the entrance of the inferior alveolar vessels and nerve. Behind this groove is a surface, for the insertion of the internal pterygoid muscle. The mandibular canal runs obliquely downward and forward in the ramus, and then horizontally forward in the body, on arriving at the incisor teeth, it turns back to communicate with the mental foramen, giving off two small canals which run to the cavities containing the incisor teeth. In the posterior two-thirds of the bone the canal is situated nearer the surface of the mandible

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

Neolithic
–
It ended when metal tools became widespread. The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops, the beginning of the Neolithic culture is considered to be in the Levant about 10, 200–8800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called proto-Neolithic is now included in the Pre-Pottery Neolithic between 10,200 and 8800 BC. By 10, 200–8800 BC, farming communities arose in the Levant and spread to Asia Minor, North Africa, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. Early Neolithic farming was limited to a range of plants, both wild and domesticated, which included einkorn wheat, millet and spelt, and the keeping of dogs, sheep. By about 6900–6400 BC, it included domesticated cattle and pigs, the establishment of permanently or seasonally inhabited settlements, not all of these cultural elements characteristic of the Neolithic appeared everywhere in the same order, the earliest farming societies in the Near East did not use pottery. Early Japanese societies and other East Asian cultures used pottery before developing agriculture, unlike the Paleolithic, when more than one human species existed, only one human species reached the Neolithic. The term Neolithic derives from the Greek νέος néos, new and λίθος líthos, stone, the term was invented by Sir John Lubbock in 1865 as a refinement of the three-age system. In the Middle East, cultures identified as Neolithic began appearing in the 10th millennium BC, early development occurred in the Levant and from there spread eastwards and westwards. Neolithic cultures are attested in southeastern Anatolia and northern Mesopotamia by around 8000 BC. The total excavated area is more than 1,200 square yards, the Neolithic 1 period began roughly 10,000 years ago in the Levant. A temple area in southeastern Turkey at Göbekli Tepe dated around 9500 BC may be regarded as the beginning of the period. This site was developed by nomadic tribes, evidenced by the lack of permanent housing in the vicinity. At least seven stone circles, covering 25 acres, contain limestone pillars carved with animals, insects, Stone tools were used by perhaps as many as hundreds of people to create the pillars, which might have supported roofs. Other early PPNA sites dating to around 9500–9000 BC have been found in Jericho, Israel, Gilgal in the Jordan Valley, the start of Neolithic 1 overlaps the Tahunian and Heavy Neolithic periods to some degree. The major advance of Neolithic 1 was true farming, in the proto-Neolithic Natufian cultures, wild cereals were harvested, and perhaps early seed selection and re-seeding occurred. The grain was ground into flour, emmer wheat was domesticated, and animals were herded and domesticated

Cave painting
–
Cave paintings are painted drawings on cave walls or ceilings, mainly of prehistoric origin, to some 40,000 years ago in Eurasia. The exact purpose of the Paleolithic cave paintings is not known, evidence suggests that they were not merely decorations of living areas since the caves in which they have been found do not have signs of ongoing habitation. They are also located in areas of caves that are not easily accessible. Some theories hold that cave paintings may have been a way of communicating with others, the paintings are remarkably similar around the world, with animals being common subjects that give the most impressive images. Humans mainly appear as images of hands, mostly hand stencils made by blowing pigment on a hand held to the wall. The earliest known cave paintings/drawings of animals are at least 35,000 years old and are found in Pettakere cave on the island of Sulawesi in Indonesia, previously it was believed that the earliest paintings were in Europe. The earliest non-figurative rock art dates back to approximately 40,000 years ago, nearly 340 caves have now been discovered in France and Spain that contain art from prehistoric times. But subsequent technology has made it possible to date the paintings by sampling the pigment itself, the choice of subject matter can also indicate chronology. For instance, the reindeer depicted in the Spanish cave of Cueva de las Monedas places the drawings in the last Ice Age. The oldest date given to a cave painting is now a pig that has a minimum age of 35,400 years old at Pettakere cave in Sulawesi. Indonesian and Australian scientists have dated other non-figurative paintings on the walls to be approximately 40,000 years old, the method they used to confirm this was dating the age of the stalactites that formed over the top of the paintings. The art is similar in style and method to that of the Indonesian caves as there were also hand stencils and this date coincides with the earliest known evidence for Homo sapiens in Europe. Because of the cave arts age, some scientists have conjectured that the paintings may have made by Neanderthals. The earliest known European figurative cave paintings are those of Chauvet Cave in France and these paintings date to earlier than 30,000 BCE according to radiocarbon dating. Some researchers believe the drawings are too advanced for this era, the radiocarbon dates from these samples show that there were two periods of creation in Chauvet,35,000 years ago and 30,000 years ago. In 2009, cavers discovered drawings in Coliboaia Cave in Romania, an initial dating puts the age of an image in the same range as Chauvet, about 32,000 years old. Some caves probably continued to be painted over a period of thousands of years. This was created roughly between 10,000 and 5,500 years ago, and painted in rock shelters under cliffs or shallow caves, though individual figures are less naturalistic, they are grouped in coherent grouped compositions to a much greater degree

Speleology
–
Speleology and caving are often connected, as the physical skills required for in situ study are the same. In Romania, the term speology is used, this is derived from a Greek word for cave, speos, rather than the Latin, spelaeum. Speleology is a field that combines the knowledge of chemistry, biology, geology, physics, meteorology and cartography to develop portraits of caves as complex. In 1895 Martel founded the Société de Spéléologie, the first organization devoted to science in the world. The creation of an accurate, detailed map is one of the most common technical activities undertaken within a cave, caves provide a home for many unique biota. Cave ecologies are diverse, and not sharply distinct from surface habitats. Generally however, the deeper the cave becomes, the more rarefied the ecology, cave environments fall into three general categories, Endogean the parts of caves that are in communication with surface soils through cracks and rock seams, groundwater seepage, and root protrusion. Parahypogean the threshold regions near cave mouths that extend to the last penetration of sunlight and these can be in regular contact with the surface via wind and underground rivers, or the migration of animals, or can be almost entirely isolated. Deep hypogean environments can host autonomous ecologies whose primary source of energy is not sunlight, cave organisms fall into three basic classes, There are also so-called accidental trogloxenes which are surface organisms that enter caves for no survival reason. Some may even be troglophobes, which survive in caves for any extended period. Examples include deer which fell through a sinkhole, frogs swept into a cave by a flash flood, the two factors that limit cave ecologies are generally energy and nutrients. To some degree moisture is available in actively forming Karst caves. Cut off from the sunlight and steady deposition of plant detritus, the majority of energy in cave environments comes from the surplus of the ecosystems outside. One major source of energy and nutrients in caves is dung from trogloxenes, because of their rarity and position in the ecosystem they are threatened by a large number of human activities. Dam construction, limestone quarrying, water pollution and logging are just some of the disasters that can devastate or destroy underground biological communities. Speleologists also work with archaeologists in studying underground ruins, tunnels, sewers and aqueducts, such as the various inlets and outlets of the Cloaca Maxima in Rome

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

Floral
–
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs, Flowers may facilitate outcrossing or allow selfing. Some flowers produce diaspores without fertilization, Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds, the essential parts of a flower can be considered in two parts, the vegetative part, consisting of petals and associated structures in the perianth, and the reproductive or sexual parts. A stereotypical flower consists of four kinds of structures attached to the tip of a short stalk, each of these kinds of parts is arranged in a whorl on the receptacle. The four main whorls are as follows, Collectively the calyx, corolla, the next whorl toward the apex, composed of units called petals, which are typically thin, soft and colored to attract animals that help the process of pollination. Androecium, the whorl, consisting of units called stamens. Stamens consist of two parts, a called a filament, topped by an anther where pollen is produced by meiosis. Gynoecium, the innermost whorl of a flower, consisting of one or more units called carpels, the carpel or multiple fused carpels form a hollow structure called an ovary, which produces ovules internally. Ovules are megasporangia and they in turn produce megaspores by meiosis which develop into female gametophytes and these give rise to egg cells. The gynoecium of a flower is described using an alternative terminology wherein the structure one sees in the innermost whorl is called a pistil. A pistil may consist of a carpel or a number of carpels fused together. The sticky tip of the pistil, the stigma, is the receptor of pollen, the supportive stalk, the style, becomes the pathway for pollen tubes to grow from pollen grains adhering to the stigma. The relationship to the gynoecium on the receptacle is described as hypogynous, perigynous, although the arrangement described above is considered typical, plant species show a wide variation in floral structure. These modifications have significance in the evolution of flowering plants and are used extensively by botanists to establish relationships among plant species, the four main parts of a flower are generally defined by their positions on the receptacle and not by their function. Many flowers lack some parts or parts may be modified into other functions and/or look like what is typically another part, in some families, like Ranunculaceae, the petals are greatly reduced and in many species the sepals are colorful and petal-like. Other flowers have modified stamens that are petal-like, the flowers of Peonies and Roses are mostly petaloid stamens
