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

American and British English spelling differences
–
Many of the differences between American and British English date back to a time when spelling standards had not yet developed. For instance, some spellings seen as American today were once used in Britain. But English-language spelling reform has rarely been adopted otherwise, and thus modern English orthography varies somewhat between countries and is far from phonemic in any country, in the early 18th century, English spelling was inconsistent. These differences became noticeable after the publishing of influential dictionaries, todays British English spellings mostly follow Johnsons A Dictionary of the English Language, while many American English spellings follow Websters An American Dictionary of the English Language. Webster was a proponent of English spelling reform for reasons both philological and nationalistic, in A Companion to the American Revolution, John Algeo notes, it is often assumed that characteristically American spellings were invented by Noah Webster. He was very influential in popularizing certain spellings in America, rather he chose already existing options such as center, color and check for the simplicity, analogy or etymology. William Shakespeares first folios, for example, used spellings like center and color as much as centre, Webster did attempt to introduce some reformed spellings, as did the Simplified Spelling Board in the early 20th century, but most were not adopted. In Britain, the influence of those who preferred the Norman spellings of words proved to be decisive, later spelling adjustments in the United Kingdom had little effect on todays American spellings and vice versa. For the most part, the systems of most Commonwealth countries. Australian spelling has also strayed slightly from British spelling, with some American spellings incorporated as standard, New Zealand spelling is almost identical to British spelling, except in the word fiord. There is also an increasing use of macrons in words that originated in Māori, most words ending in an unstressed -our in British English end in -or in American English. Wherever the vowel is unreduced in pronunciation, e. g. contour, velour, paramour and troubadour the spelling is the same everywhere, most words of this kind came from Latin, where the ending was spelled -or. They were first adopted into English from early Old French, after the Norman conquest of England, the ending became -our to match the Old French spelling. The -our ending was not only used in new English borrowings, however, -or was still sometimes found, and the first three folios of Shakespeares plays used both spellings before they were standardised to -our in the Fourth Folio of 1685. After the Renaissance, new borrowings from Latin were taken up with their original -or ending, Websters 1828 dictionary had only -or and is given much of the credit for the adoption of this form in the United States. Johnson, unlike Webster, was not an advocate of spelling reform and he preferred French over Latin spellings because, as he put it, the French generally supplied us. In Jeffersons original draft it is spelled honour, Honor and honour were equally frequent in Britain until the 17th century, honor still is, in the UK, the usual spelling as a persons name and appears in Honor Oak, a district of London. In derivatives and inflected forms of the words, British usage depends on the nature of the suffix used

Urban area
–
An urban area is a human settlement with high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, in urbanism, the term contrasts to rural areas such as villages and hamlets and in urban sociology or urban anthropology it contrasts with natural environment. The worlds urban population in 1950 of just 746 million has increased to 3.9 billion in the decades since, in 2009, the number of people living in urban areas surpassed the number living in rural areas and since then the world has become more urban than rural. This was the first time that the majority of the population lived in a city. In 2014 there were 7.25 billion people living on the planet, Urban areas are created and further developed by the process of urbanization. Urban areas are measured for various purposes, including analyzing population density, historian John Gurda writes, I have tried to uncover Milwaukees civic bedrock - the shifting foundation on which individuals have built their lives and the community has constructed its identity. There is no doubt that the deepest layer of bedrock is economic. In every age, people have chosen to live in areas not because of their climates or landmarks or cultural attractions. It was economic opportunity that brought people to Milwaukee, and it is economic opportunity that keeps them there, I define cities as concentrations of people animated by concentrations of capital. More simply put, money is the root of all cities, official definitions vary somewhat between nations. The ten largest metropolitan areas account for half of the population, about 3 million people live in Buenos Aires City and the Greater Buenos Aires metropolitan area totals around 13 million, making it one of the largest urban areas in the world. The metropolitan areas of Córdoba, Rosario, Mendoza and Tucumán have around 1.3 million inhabitants each and La Plata, seven other provinces have over one million people each, Mendoza, Tucumán, Entre Ríos, Salta, Chaco, Corrientes and Misiones. According to IBGE urban areas already concentrate 84. 35% of the population, while the Southeast region remains the most populated one, with over 80 million inhabitants. The largest metropolitan areas in Brazil are São Paulo, Rio de Janeiro, and Belo Horizonte — all in the Southeastern Region — with 20,12, and 5 million inhabitants respectively. The majority of state capitals are the largest cities in their states, except for Vitória, the capital of Espírito Santo, and Florianópolis, there are also non-capital metropolitan areas in the states of São Paulo, Minas Gerais, Rio Grande do Sul and Santa Catarina. According to Statistics Canada, an area in Canada is an area with a population of at least 1,000 people where the density is no fewer than 400 persons per square kilometre. If two or more areas are within 2 km of each other by road, they are merged into a single urban area. Accordingly, the new definition set out three types of population centres, small, medium and large

Social stratification
–
Social stratification is a societys categorization of people into socioeconomic strata, based upon their occupation and income, wealth and social status, or derived power. As such, stratification is the social position of persons within a social group, category, geographic region. The upper-stratum, the middle-stratum, and the lower stratum, moreover, a social stratum can be formed upon the bases of kinship or caste, or both. Determining the structures of social stratification arises from inequalities of status among persons, therefore, generally, the greater the social complexity of a society, the more social strata exist, by way of social differentiation. Social stratification is a used in the social sciences to describe the relative social position of persons in a given social group, category. In modern Western societies, stratification is often classified into three major divisions of social class, upper class, middle class, and lower class. Each of these classes can be subdivided into smaller classes. Social strata may also be delineated on the basis of kinship ties or caste relations, the concept of social stratification is often used and interpreted differently within specific theories. So-called conflict theories, such as Marxism, point to the inaccessibility of resources, talcott Parsons, an American sociologist, asserted that stability and social order are regulated, in part, by universal values. Such values are not identical with consensus but can as well be an impetus for ardent social conflict as it has multiple times through history. Parsons never claimed that universal values, in and by themselves, indeed, the constitution of society is a much more complicated codification of emerging historical factors. Theorists such as Ralf Dahrendorf alternately note the tendency toward an enlarged middle-class in modern Western societies due to the necessity of a workforce in technological economies. Various social and political perspectives concerning globalization, such as dependency theory, four principles are posited to underlie social stratification. First, social stratification is socially defined as a property of a society rather than individuals in that society, second, social stratification is reproduced from generation to generation. Third, social stratification is universal but variable, fourth, social stratification involves not just quantitative inequality but qualitative beliefs and attitudes about social status. Although stratification is not limited to complex societies, all complex societies exhibit features of stratification, the term stratification system is sometimes used to refer to the complex social relationships and social structure that generate these observed inequalities. Social mobility is the movement of individuals, social groups or categories of people between the layers or strata in a stratification system and this movement can be intragenerational or intergenerational. Such mobility is used to classify different systems of social stratification

Elite
–
Elite, is a term that originates from Latin eligere. In political and sociological theory for a group of powerful people that controls a disproportionate amount of wealth. Insofar as national events are decided, the elite are those who decide them. Mills states that the elite members recognize other members mutual exalted position in society. As a rule, hey accept one another, understand one another, marry one another, tend to work and to think and it is a well-regulated existence where education plays a critical role. These memberships in turn pave the way to the prominent social clubs located in all major cities, the Military Circle, In Mills time a heightened concern about warfare existed, making top military leaders and such issues as defense funding and personnel recruitment very important. Most prominent corporate leaders and politicians were strong proponents of military spending and these two groups tended to be mutually supportive. Unlike the ruling class, a formation based on heritage and social ties. According to Mills, the power elite rose from the reorganization of the propertied classes into the more or less unified stratum of the corporate rich. Domhoff further clarified the differences in the two terms, The upper class as a whole does not do the ruling, Power elite is a term used by American sociologist C. Wright Mills to describe a relatively small, loosely connected group of individuals who dominate American policymaking. The basis for membership of a power élite is institutional power, one study of power élites in the United States under President George W. Bush identified 7,314 institutional positions of power encompassing 5,778 individuals. A later study of U. S. Ethnicity White Anglo-Saxons dominate in the power élite, with Protestants representing about 80 percent of the top business leaders, education Nearly all the leaders have a college education, with almost half graduating with advanced degrees. About 54 percent of the leaders and 42% of the government élite graduated from just 12 prestigious universities with large endowments. Social clubs Most holders of top positions in the power élite possess exclusive membership in one or more social clubs. About a third belong to a number of especially prestigious clubs in major cities like London, New York City, Chicago, Boston. In the 1970s an organized set of policies promoted reduced taxes, especially for the wealthy, starting with legislation in the 1980s, the wealthy banking community successfully lobbied for reduced regulation. Doing so would hopefully alleviate various destructive conditions affecting large numbers of affluent citizens. Mills determined that there is a core of the power elite involving individuals that are able to move from one seat of institutional power to another

Symbol
–
A symbol is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship. Symbols allow people to go beyond what is known or seen by creating linkages between otherwise very different concepts and experiences, all communication is achieved through the use of symbols. Symbols take the form of words, sounds, gestures, ideas or visual images and are used to other ideas. For example, a red octagon may be a symbol for STOP, on a map, a blue line might represent a river. Alphabetic letters may be symbols for sounds, personal names are symbols representing individuals. A red rose may symbolize love and compassion, the variable x, in a mathematical equation, may symbolize the position of a particle in space. In cartography, a collection of symbols forms a legend for a map The word derives from the Greek symbolon meaning token or watchword. It is an amalgam of syn- together + bole a throwing, a casting, the sense evolution in Greek is from throwing things together to contrasting to comparing to token used in comparisons to determine if something is genuine. The meaning something which stands for something else was first recorded in 1590, later, expanding on what he means by this definition Campbell says, a symbol, like everything else, shows a double aspect. We must distinguish, therefore between the sense and the meaning of the symbol. The term meaning can only to the first two but these, today, are in the charge of science – which is the province as we have said, not of symbols. The ineffable, the unknowable, can be only sensed. Heinrich Zimmer gives an overview of the nature, and perennial relevance. Concepts and words are symbols, just as visions, rituals, through all of these a transcendent reality is mirrored. They are so many metaphors reflecting and implying something which, though thus variously expressed, is ineffable, though thus rendered multiform, Symbols hold the mind to truth but are not themselves the truth, hence it is delusory to borrow them. Each civilisation, every age, must bring forth its own, in the book Signs and Symbols, it is stated that A symbol. Is a visual image or sign representing an idea -- a deeper indicator of a universal truth, Symbols are a means of complex communication that often can have multiple levels of meaning. This separates symbols from signs, as signs have only one meaning, human cultures use symbols to express specific ideologies and social structures and to represent aspects of their specific culture

Writing system
–
A writing system is any conventional method of visually representing verbal communication. While both writing and speech are useful in conveying messages, writing differs in also being a form of information storage. The processes of encoding and decoding writing systems involve shared understanding between writers and readers of the meaning behind the sets of characters that make up a script, the general attributes of writing systems can be placed into broad categories such as alphabets, syllabaries, or logographies. Any particular system can have attributes of more than one category, in the alphabetic category, there is a standard set of letters of consonants and vowels that encode based on the general principle that the letters represent speech sounds. In a syllabary, each symbol correlates to a syllable or mora, in a logography, each character represents a word, morpheme, or other semantic units. Other categories include abjads, which differ from alphabets in that vowels are not indicated, alphabets typically use a set of 20-to-35 symbols to fully express a language, whereas syllabaries can have 80-to-100, and logographies can have several hundreds of symbols. Systems will also enable the stringing together of these groupings in order to enable a full expression of the language. The reading step can be accomplished purely in the mind as an internal process, writing systems were preceded by proto-writing, which used pictograms, ideograms and other mnemonic symbols. Proto-writing lacked the ability to capture and express a range of thoughts. Soon after, writing provided a form of long distance communication. With the advent of publishing, it provided the medium for a form of mass communication. Writing systems are distinguished from other possible symbolic communication systems in that a system is always associated with at least one spoken language. In contrast, visual representations such as drawings, paintings, and non-verbal items on maps, such as contour lines, are not language-related. Some other symbols, such as numerals and the ampersand, are not directly linked to any specific language, every human community possesses language, which many regard as an innate and defining condition of humanity. However, the development of writing systems, and the process by which they have supplanted traditional oral systems of communication, have been sporadic, uneven, once established, writing systems generally change more slowly than their spoken counterparts. Thus they often preserve features and expressions which are no current in the spoken language. One of the benefits of writing systems is that they can preserve a permanent record of information expressed in a language. In the examination of individual scripts, the study of writing systems has developed along partially independent lines, thus, the terminology employed differs somewhat from field to field

Natural environment
–
The natural environment encompasses all living and non-living things occurring naturally. The term is most often applied to the Earth or some part of Earth and this environment encompasses the interaction of all living species, climate, weather, and natural resources that affect human survival and economic activity. Even acts which seem less extreme, such as building a mud hut or a system in the desert. Though many animals build things to provide an environment for themselves, they are not human, hence beaver dams. People seldom find absolutely natural environments on Earth, and naturalness usually varies in a continuum, more precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in a field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil. Natural environment is used as a synonym for habitat. For instance, when we say that the environment of giraffes is the savanna. Earth science generally recognizes 4 spheres, the lithosphere, the hydrosphere, the atmosphere, and the biosphere as correspondent to rocks, water, air, and life respectively. Some scientists include, as part of the spheres of the Earth, Earth science, is an all-embracing term for the sciences related to the planet Earth. There are four major disciplines in sciences, namely geography, geology, geophysics. These major disciplines use physics, chemistry, biology, chronology, the Earths crust, or lithosphere, is the outermost solid surface of the planet and is chemically and mechanically different from underlying mantle. It has been generated greatly by igneous processes in which magma cools, beneath the lithosphere lies the mantle which is heated by the decay of radioactive elements. The mantle though solid is in a state of rheic convection and this convection process causes the lithospheric plates to move, albeit slowly. The resulting process is known as plate tectonics, volcanoes result primarily from the melting of subducted crust material or of rising mantle at mid-ocean ridges and mantle plumes. An ocean is a body of saline water, and a component of the hydrosphere. Approximately 71% of the Earths surface is covered by ocean, a body of water that is customarily divided into several principal oceans. More than half of area is over 3,000 meters deep

Domestication
–
Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors. There is a difference between domestic and wild populations. The dog was the first domesticated vertebrate, and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. Among birds, the domestic species today is the chicken, important for meat and eggs, though economically valuable poultry include the turkey, guineafowl. Birds are also kept as cagebirds, from songbirds to parrots. The longest established invertebrate domesticates are the bee and the silkworm. Terrestrial snails are raised for food, while species from several phyla are kept for research, the domestication of plants began at least 12,000 years ago with cereals in the Middle East, and the bottle gourd in Asia. Agriculture developed in at least 11 different centres around the world, domesticating different crops, Domestication means belonging to the house. Animals domesticated for home companionship are usually called pets, while those domesticated for food or work are called livestock or farm animals and this definition recognizes both the biological and the cultural components of the domestication process and the impacts on both humans and the domesticated animals and plants. All past definitions of domestication have included a relationship between humans with plants and animals, but their differences lay in who was considered as the partner in the relationship. This new definition recognizes a mutualistic relationship in both partners gain benefits. Domestication has vastly enhanced the reproductive output of crop plants, livestock, Domestication syndrome is the suite of phenotypic traits arising during domestication that distinguish crops from their wild ancestors. The domestication of animals is the relationship between animals with the humans who have influence on their care and reproduction. Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors, there is a genetic difference between domestic and wild populations. Domestication should not be confused with taming, the beginnings of animal domestication involved a protracted coevolutionary process with multiple stages along different pathways. The dog was the first domesticant, and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. Humans did not intend to domesticate animals from, or at least they did not envision a domesticated animal resulting from, in both of these cases, humans became entangled with these species as the relationship between them, and the human role in their survival and reproduction, intensified. Although the directed pathway proceeded from capture to taming, the two pathways are not as goal-oriented and archaeological records suggest that they take place over much longer time frames
10.
Monument
–
The term monument is often applied to buildings or structures that are considered examples of important architectural and/or cultural heritage. Monuments have been created for thousands of years, and they are often the most durable, in more recent times, monumental structures such as the Statue of Liberty and Eiffel Tower have become iconic emblems of modern nation-states. The term monumentality relates to the status and physical presence of a monument. Monuments are frequently used to improve the appearance of a city or location, planned cities such as Washington D. C. New Delhi and Brasília are often built around monuments, for example, the Washington Monuments location was conceived by LEnfant to help organize public space in the city, before it was designed or constructed. Older cities have monuments placed at locations that are important or are sometimes redesigned to focus on one. As Shelley suggested in his famous poem Ozymandias, the purpose of monuments is often to impress or awe. Structures created for purposes that have been made notable by their age. This can happen because of age and size, as in the case of the Great Wall of China. Monuments are also designed to convey historical or political information. They can be used to reinforce the primacy of political power. The social meanings of monuments are rarely fixed and certain and are contested by different social groups. This contention of meaning is a theme of modern post processual archaeological discourse. Until recently, it was customary for archaeologists to study large monuments, New ideas about what constitutes the archaeological record have revealed that certain legislative and theoretical approaches to the subject are too focused on earlier definitions of monuments. An example has been the United Kingdoms Scheduled Ancient Monument laws, recently, more and more monuments are being preserved digitally through organisations as CyArk. Cenotaphs and other memorials to commemorate the dead, usually war casualties, e. g. India Gate and Vimy Ridge Memorial, or disaster casualties, such as the Titanic Memorial, Belfast. Church monuments to commemorate the dead, located above or near their grave, often featuring an effigy, columns, often topped with a statue, e. g. Berlin Victory Column, Nelsons Column in London, and Trajans Column in Rome. Gravestones, small monuments to the deceased, placed at their gravesites, e. g. the tombs and vaults of veterans in Les Invalides, mausoleums and tombs to honor the dead, e. g. the Great Pyramid of Giza and Taj Mahal

Architecture
–
Architecture is both the process and the product of planning, designing, and constructing buildings and other physical structures. Architectural works, in the form of buildings, are often perceived as cultural symbols. Historical civilizations are often identified with their surviving architectural achievements, Architecture can mean, A general term to describe buildings and other physical structures. The art and science of designing buildings and nonbuilding structures, the style of design and method of construction of buildings and other physical structures. A unifying or coherent form or structure Knowledge of art, science, technology, the design activity of the architect, from the macro-level to the micro-level. The practice of the architect, where architecture means offering or rendering services in connection with the design and construction of buildings. The earliest surviving work on the subject of architecture is De architectura. According to Vitruvius, a building should satisfy the three principles of firmitas, utilitas, venustas, commonly known by the original translation – firmness, commodity. An equivalent in modern English would be, Durability – a building should stand up robustly, utility – it should be suitable for the purposes for which it is used. Beauty – it should be aesthetically pleasing, according to Vitruvius, the architect should strive to fulfill each of these three attributes as well as possible. Leon Battista Alberti, who elaborates on the ideas of Vitruvius in his treatise, De Re Aedificatoria, saw beauty primarily as a matter of proportion, for Alberti, the rules of proportion were those that governed the idealised human figure, the Golden mean. The most important aspect of beauty was, therefore, an inherent part of an object, rather than something applied superficially, Gothic architecture, Pugin believed, was the only true Christian form of architecture. The 19th-century English art critic, John Ruskin, in his Seven Lamps of Architecture, Architecture was the art which so disposes and adorns the edifices raised by men. That the sight of them contributes to his health, power. For Ruskin, the aesthetic was of overriding significance and his work goes on to state that a building is not truly a work of architecture unless it is in some way adorned. For Ruskin, a well-constructed, well-proportioned, functional building needed string courses or rustication, but suddenly you touch my heart, you do me good. I am happy and I say, This is beautiful, le Corbusiers contemporary Ludwig Mies van der Rohe said Architecture starts when you carefully put two bricks together. The notable 19th-century architect of skyscrapers, Louis Sullivan, promoted an overriding precept to architectural design, function came to be seen as encompassing all criteria of the use, perception and enjoyment of a building, not only practical but also aesthetic, psychological and cultural
12.
Taxation
–
A tax is a financial charge or other levy imposed upon a taxpayer by a state or the functional equivalent of a state to fund various public expenditures. A failure to pay, or evasion of or resistance to taxation, is punishable by law. Taxes consist of direct or indirect taxes and may be paid in money or as its labour equivalent, the legal definition and the economic definition of taxes differ in that economists do not regard many transfers to governments as taxes. For example, some transfers to the sector are comparable to prices. Examples include tuition at public universities and fees for utilities provided by local governments, governments also obtain resources by creating money and coins, through voluntary gifts, by imposing penalties, by borrowing, and by confiscating wealth. In modern taxation systems, governments levy taxes in money, but in-kind and corvée taxation are characteristic of traditional or pre-capitalist states, the method of taxation and the government expenditure of taxes raised is often highly debated in politics and economics. Tax collection is performed by a government agency such as the Canada Revenue Agency, when taxes are not fully paid, the state may impose civil penalties or criminal penalties on the non-paying entity or individual. The levying of taxes aims to raise revenue to fund governing and/or to alter prices in order to affect demand, States and their functional equivalents throughout history have used money provided by taxation to carry out many functions. A governments ability to raise taxes is called its fiscal capacity, when expenditures exceed tax revenue, a government accumulates debt. A portion of taxes may be used to service past debts, governments also use taxes to fund welfare and public services. These services can include education systems, pensions for the elderly, unemployment benefits, energy, water and waste management systems are also common public utilities. A tax effectively changes relative prices of products and they have therefore sought to identify the kind of tax system that would minimize this distortion. Governments use different kinds of taxes and vary the tax rates, historically, taxes on the poor supported the nobility, modern social-security systems aim to support the poor, the disabled, or the retired by taxes on those who are still working. A states tax system often reflects its communal values and the values of those in current political power. To create a system of taxation, a state must make choices regarding the distribution of the tax burden—who will pay taxes and how much they will pay—and how the taxes collected will be spent. In democratic nations where the public elects those in charge of establishing or administering the tax system, in countries where the public does not have a significant amount of influence over the system of taxation, that system may reflect more closely the values of those in power. All large businesses incur administrative costs in the process of delivering revenue collected from customers to the suppliers of the goods or services being purchased. Taxation is no different, the resource collected from the public through taxation is always greater than the amount which can be used by the government, the difference is called the compliance cost and includes the labour cost and other expenses incurred in complying with tax laws and rules

Farming
–
A farm is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops, it is the basic facility in food production. It includes ranches, feedlots, orchards, plantations and estates, smallholdings and hobby farms, in modern times the term has been extended so as to include such industrial operations as wind farms and fish farms, both of which can operate on land or sea. Farming originated independently in different parts of the world, as hunter gatherer societies transitioned to food production rather than, food capture. It may have started about 12,000 years ago with the domestication of livestock in the Fertile Crescent in western Asia, modern farms in developed countries are highly mechanized. In Europe, traditional farms are giving way to larger production units. In Australia, some farms are large because the land is unable to support a high stocking density of livestock because of climatic conditions. In less developed countries, small farms are the norm, the word is from the medieval Latin noun firma, also the source of the French word ferme, meaning a fixed agreement, contract, from the classical Latin adjective firmus meaning strong, stout, firm. Farming has been innovated at multiple different points and places in human history and it was the worlds first historically verifiable revolution in agriculture. Subsequent step-changes in human farming practices were provoked by the British Agricultural Revolution in the 18th century, farming spread from the Middle East to Europe and by 4,000 BC people that lived in the central part of Europe were using oxen to pull plows and wagons. A farm may operate under a system or with a variety of cereal or arable crops. Specialist farms are often denoted as such, thus a dairy farm, fish farm, some farms may not use the word at all, hence vineyard, orchard, market garden or truck farm. Some farms may be denoted by their location, such as a hill farm. Many other terms are used to describe farms to denote their methods of production, as in collective, corporate, intensive, organic or vertical. There are many breeds of cattle that can be milked some of the best producing ones include Holstein, Norwegian Red, Kostroma, Brown Swiss, in most Western countries, a centralized dairy facility processes milk and dairy products, such as cream, butter, and cheese. In the United States, these dairies are usually local companies, dairy farms generally sell male calves for veal meat, as dairy breeds are not normally satisfactory for commercial beef production. Many dairy farms also grow their own feed, typically including corn, alfalfa and this is fed directly to the cows, or stored as silage for use during the winter season. Additional dietary supplements are added to the feed to milk production. Poultry farms are devoted to raising chickens, turkeys, ducks, a pig farm is one that specializes in raising pigs or hogs for bacon, ham and other pork products and may be free range, intensive, or both

Nomadic pastoralist
–
Nomadic pastoralism is a form of pastoralism when livestock are herded in order to find fresh pastures on which to graze. Strictly speaking, true nomads follow a pattern of movement. However this distinction is not observed and the term nomad used for both—in historical cases the regularity of movements is often unknown in any case. The herded livestock include cattle, yaks, sheep, goats, reindeer, horses, donkeys or camels, nomadic pastoralism is commonly practised in regions with little arable land, typically in the developing world, especially in the steppe lands north of the agricultural zone of Eurasia. Of the estimated 30–40 million nomadic pastoralists worldwide, most are found in central Asia, increasing numbers of stock may lead to overgrazing of the area and desertification if lands are not allowed to fully recover between one grazing period and the next. Increased enclosure and fencing of land has reduced the amount of available for this practice. The nomadic pastoralism was a result of the Neolithic revolution, during the revolution, humans began domesticating animals and plants for food and started forming cities. Nomadism generally has existed in symbiosis with such settled cultures trading animal products for manufactured items not produced by the nomadic herders, often traditional nomadic groups settle into a regular seasonal pattern of transhumance. An example of a normal cycle in the northern hemisphere is. The movements in this example are about 180 to 200 km, camps are established in the same place each year, often semi-permanent shelters are built in at least one place on this migration route. In sub-regions such as Chad, the nomadic pastoralist cycle is as follows, In the rainy season, the villages are often made of sturdy material as clay. Old men and women remain in this village when the people move the herds in the dry season. In the dry season, the people move their herds to southern villages with a temporary character. They then move inland, where they stay in tent camps, in Chad, the sturdy villages are called hillé, the less sturdy villages are called dankhout and the tents ferik. Nomadic pastoralism was historically widespread throughout less fertile regions of Earth and it is found in areas of low rainfall such as the Arabian Peninsula inhabited by Bedouins, as well as Northeast Africa inhabited by Somalis. Nomadic transhumance is also common in areas of climate, such as Northern Europe and Russia inhabited by the indigenous Sami people, Nenets people. There are an estimated 30-40 million nomads in the world, pastoral nomads and semi-nomadic pastoralists form a significant but declining minority in such countries as Saudi Arabia, Iran, and Afghanistan. They comprise less than 2% of the population in the countries of North Africa except Libya, some remnants of these populations are nomadic to this day

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

Hunter-gather
–
A hunter-gatherer is a human living in a society in which most or all food is obtained by foraging, in contrast to agricultural societies, which rely mainly on domesticated species. Hunting and gathering was humanitys first and most successful adaptation, occupying at least 90 percent of human history, following the invention of agriculture, hunter-gatherers who did not change have been displaced or conquered by farming or pastoralist groups in most parts of the world. Only a few contemporary societies are classified as hunter-gatherers, and many supplement their activity with horticulture and/or keeping animals. In the 1970s, Lewis Binford suggested that humans were obtaining food via scavenging. Early humans in the Lower Paleolithic lived in forests and woodlands, which allowed them to collect seafood, eggs, nuts, and fruits besides scavenging. Rather than killing large animals for meat, according to this view and this hypothesis does not necessarily contradict the scavenging hypothesis, both subsistence strategies could have been in use – sequentially, alternating or even simultaneously. It remained the only mode of subsistence until the end of the Mesolithic period some 10,000 years ago and this specialization of work also involved creating specialized tools such as, fishing nets, hooks, and bone harpoons. The transition into the subsequent Neolithic period is defined by the unprecedented development of nascent agricultural practices. Agriculture originated and spread in different areas including the Middle East, Asia, Mesoamerica. Forest gardening was also being used as a production system in various parts of the world over this period. Forest gardens originated in prehistoric times along jungle-clad river banks and in the wet foothills of monsoon regions, in the gradual process of families improving their immediate environment, useful tree and vine species were identified, protected and improved, whilst undesirable species were eliminated. Eventually superior introduced species were selected and incorporated into the gardens, many groups continued their hunter-gatherer ways of life, although their numbers have continually declined, partly as a result of pressure from growing agricultural and pastoral communities. Many of them reside in the world, either in arid regions or tropical forests. Areas that were available to hunter-gatherers were—and continue to be—encroached upon by the settlements of agriculturalists. In the resulting competition for use, hunter-gatherer societies either adopted these practices or moved to other areas. In addition, Jared Diamond has blamed a decline in the availability of wild foods, as the number and size of agricultural societies increased, they expanded into lands traditionally used by hunter-gatherers. As a result of the now near-universal human reliance upon agriculture, archaeologists can use evidence such as stone tool use to track hunter-gatherer activities, including mobility. Most hunter-gatherers are nomadic or semi-nomadic and live in temporary settlements, mobile communities typically construct shelters using impermanent building materials, or they may use natural rock shelters, where they are available
17.
Hierarchy
–
A hierarchy is an arrangement of items in which the items are represented as being above, below, or at the same level as one another. A hierarchy can link entities either directly or indirectly, and either vertically or diagonally, indirect hierarchical links can extend vertically upwards or downwards via multiple links in the same direction, following a path. This is akin to two co-workers or colleagues, each reports to a superior, but they have the same relative amount of authority. Organizational forms exist that are alternative and complementary to hierarchy. A hierarchy is a system or organization in which people or groups are ranked one above the other according to status or authority, Hierarchies have their own special vocabulary. Most hierarchies use a more specific vocabulary pertaining to their subject, for example, with data structures, objects are known as nodes, superiors are called parents and subordinates are called children. In a business setting, a superior is a supervisor/boss and a peer is a colleague, degree of branching refers to the number of direct subordinates or children an object has a node has). Hierarchies can be categorized based on the degree, the highest degree present in the system as a whole. Categorization in this way yields two broad classes, linear and branching, in a linear hierarchy, the maximum degree is 1. In other words, all of the objects can be visualized in a lineup, note that this is referring to the objects and not the levels, every hierarchy has this property with respect to levels, but normally each level can have an infinite number of objects. An example of a hierarchy is the hierarchy of life. In a branching hierarchy, one or more objects has a degree of 2 or more, for many people, the word hierarchy automatically evokes an image of a branching hierarchy. Branching hierarchies are present within numerous systems, including organizations and classification schemes, the broad category of branching hierarchies can be further subdivided based on the degree. A flat hierarchy is a hierarchy in which the maximum degree approaches infinity. Most often, systems intuitively regarded as hierarchical have at most a moderate span, therefore, a flat hierarchy is often not viewed as a hierarchy at all. For example, diamonds and graphite are flat hierarchies of numerous carbon atoms which can be decomposed into subatomic particles. An overlapping hierarchy is a hierarchy in which at least one object has two parent objects. Pseudo-Dionysius used the related Greek word both in reference to the hierarchy and the ecclesiastical hierarchy

Social class
–
Class is an essential object of analysis for sociologists, political scientists, anthropologists, and social historians. However, there is not a consensus on the best definition of the class, the precise measurements of what determines social class in society has varied over time. According to philosopher Karl Marx, class is determined entirely by ones relationship to the means of production, the term class is etymologically derived from the Latin classis, which was used by census takers to categorize citizens by wealth, in order to determine military service obligations. In the late 18th century, the class began to replace classifications such as estates, rank. Historically social class and behavior was sometimes laid down in law, definitions of social classes reflect a number of sociological perspectives, informed by anthropology, economics, psychology, and sociology. The major perspectives historically have been Marxism and Structural functionalism, the common stratum model of class divides society into a simple hierarchy of working class, middle class and upper class. For Marx, class is a combination of objective and subjective factors, objectively, a class shares a common relationship to the means of production. Subjectively, the members will necessarily have some perception of their similarity, Class consciousness is not simply an awareness of ones own class interest but is also a set of shared views regarding how society should be organized legally, culturally, socially and politically. These class relations are reproduced through time and this is the fundamental economic structure of work and property, a state of inequality that is normalized and reproduced through cultural ideology. Marxists explain the history of civilized societies in terms of a war of classes between those who control production and those who produce the goods or services in society, in the Marxist view of capitalism, this is a conflict between capitalists and wage-workers. Furthermore, in countries where modern civilisation has become fully developed, an industrial army of workmen, under the command of a capitalist, requires, like a real army, officers and sergeants who, while the work is being done, command in the name of the capitalist. This would mark the beginning of a society in which human needs rather than profit would be motive for production. In a society with democratic control and production for use, there would be no class, no state and no need for financial and banking institutions and money. Max Weber formulated a three-component theory of stratification, that saw social class as emerging from an interplay between class, status and power. Weber believed that class position was determined by a relationship to the means of production. Weber derived many of his key concepts on social stratification by examining the structure of many countries. He noted that contrary to Marxs theories, stratification was based on more than simply ownership of capital, Weber pointed out that some members of the aristocracy lack economic wealth yet might nevertheless have political power. Likewise in Europe, many wealthy Jewish families in lack prestige and honor, Class, A persons economic position in a society

Neolithic Revolution
–
These settled communities permitted humans to observe and experiment with plants to learn how they grew and developed. This new knowledge led to the domestication of plants and it was the worlds first historically verifiable revolution in agriculture. The Neolithic Revolution greatly narrowed the diversity of available, with a switch to agriculture which led to a downturn in human nutrition. The Neolithic Revolution involved far more than the adoption of a set of food-producing techniques. These societies radically modified their natural environment by means of specialized food-crop cultivation which allowed extensive surplus food production, personal land and private property ownership led to an hierarchical society, with an elite Social class, comprising a nobility, polity, and military. The first fully developed manifestation of the entire Neolithic complex is seen in the Middle Eastern Sumerian cities, the Levant followed by Mesopotamia are the sites of the earliest developments of the Neolithic Revolution from around 10,000 BC. The term Neolithic Revolution was coined in 1923 by V. Gordon Childe to describe the first in a series of revolutions in Middle Eastern history. The beginning of process in different regions has been dated from 10,000 to 8,000 BC in the Fertile Crescent. Recent archaeological research suggests that in regions such as the Southeast Asian peninsula, the transition from hunter-gatherer to agriculturalist was not linear. There are several competing theories as to the factors that drove populations to take up agriculture. The most prominent of these are, The Oasis Theory, originally proposed by Raphael Pumpelly in 1908, popularized by V. Gordon Childe in 1928 and summarised in Childes book Man Makes Himself. However, today this theory has little support amongst archaeologists because subsequent climate data suggests that the region was getting wetter rather than drier, the Feasting model by Brian Hayden suggests that agriculture was driven by ostentatious displays of power, such as giving feasts, to exert dominance. This required assembling large quantities of food, which drove agricultural technology, various social and economic factors helped drive the need for food. The evolutionary/intentionality theory, developed by David Rindos and others, views agriculture as an adaptation of plants. Starting with domestication by protection of plants, it led to specialization of location. Peter Richerson, Robert Boyd, and Robert Bettinger make a case for the development of agriculture coinciding with a stable climate at the beginning of the Holocene. Ronald Wrights book and Massey Lecture Series A Short History of Progress popularized this hypothesis, leonid Grinin argues that whatever plants were cultivated, the independent invention of agriculture always took place in special natural environments. It is supposed that the cultivation of cereals started somewhere in the Near East, andrew Moore suggested that the Neolithic Revolution originated over long periods of development in the Levant, possibly beginning during the Epipaleolithic

State formation
–
State formation is the process of the development of a centralized government structure in a situation where one did not exist prior to its development. The study of formation is divided generally into either the study of early states or the study of modern states. Academic debate about various theories is a prominent feature in fields like Anthropology, Sociology, Economics, there is no clear consensus on the defining characteristics of a state and the definition can vary significantly based upon the focus of the particular study. Theories of state formation have two distinct focuses, depending largely on the field of study, the transition in human society from tribal communities into larger political organizations. Studies of this topic, often in anthropology, explore the development of basic administrative structures in areas where states developed from stateless societies. In contrast, studies in science and in sociology have focused significantly on the formation of the modern state. Primary states are defined by anthropologists Spencer & Redmond as those states that developed in a context with no contact or prior development of a state in the area and these are those situations where states developed for the first time in that social environment. Studies on the formation of early states tend to focus on processes that create, examples of early states which developed in interaction with other states include the Aegean Bronze Age Greek civilizations and the Malagasy civilization in Madagascar. Early state formation causation can thus include borrowing, imposition, however, some scholars hold that the modern state model formed in other parts of the world prior to colonialism, but that colonial structures replaced it. There are a number of different theories and hypotheses regarding early state formation that seek generalizations to explain why the state developed in some places, other scholars believe that generalizations are unhelpful and that each case of early state formation should be treated on its own. Voluntary theories contend that diverse groups of people together to form states as a result of some shared rational interest. The theories largely focus on the development of agriculture, and the population, the argument is that such pressures result in integrative pressure for rational people to unify and create a state. Much of the social contract philosophical traditional proposed a theory for state formation. The theory was most significantly detailed Karl August Wittfogels argument that, in arid environments, in addition to this, is what Carneiro calls the automatic hypothesis, which contends that the development of agriculture easily produces conditions necessary for the development of a state. With surplus food stocks created by development, creation of distinct worker classes. For example, the trade in the 16th century may have been a key to state formation in West African states such as Whydah, Dahomey. Conflict theories of state formation regard conflict and dominance of some population over another population as key to the formation of states. A number of different theories rely on conflict, dominance, or oppression as a process or as a necessary mechanism within certain conditions

Middle East
–
The Middle East is a transcontinental region centered on Western Asia and Egypt. The corresponding adjective is Middle-Eastern and the noun is Middle-Easterner. The term has come into usage as a replacement of the term Near East beginning in the early 20th century. Arabs, Turks, Persians, Kurds, and Azeris constitute the largest ethnic groups in the region by population. Indigenous minorities of the Middle East include Jews, Assyrians and other Arameans, Baloch, Berbers, Copts, Druze, Lurs, Mandaeans, Samaritans, Shabaks, Tats, in the Middle East, there is also a Romani community. European ethnic groups form a diaspora in the region include Albanians, Bosniaks, Circassians, Crimean Tatars, Franco-Levantines. Among other migrant populations are Bengalis as well as other Indians, Chinese, Filipinos, Indonesians, Pakistanis, the history of the Middle East dates back to ancient times, with the importance of the region being recognized for millennia. Most of the countries border the Persian Gulf have vast reserves of crude oil. The term Middle East may have originated in the 1850s in the British India Office, however, it became more widely known when American naval strategist Alfred Thayer Mahan used the term in 1902 to designate the area between Arabia and India. During this time the British and Russian Empires were vying for influence in Central Asia, Mahan realized not only the strategic importance of the region, but also of its center, the Persian Gulf. Mahan first used the term in his article The Persian Gulf and International Relations, published in September 1902 in the National Review, a British journal. The Middle East, if I may adopt a term which I have not seen, will some day need its Malta, as well as its Gibraltar, it does not follow that either will be in the Persian Gulf. The British Navy should have the facility to concentrate in force if occasion arise, about Aden, India, mahans article was reprinted in The Times and followed in October by a 20-article series entitled The Middle Eastern Question, written by Sir Ignatius Valentine Chirol. During this series, Sir Ignatius expanded the definition of Middle East to include regions of Asia which extend to the borders of India or command the approaches to India. After the series ended in 1903, The Times removed quotation marks from subsequent uses of the term, in the late 1930s, the British established the Middle East Command, which was based in Cairo, for its military forces in the region. After that time, the term Middle East gained broader usage in Europe, the description Middle has also led to some confusion over changing definitions. Before the First World War, Near East was used in English to refer to the Balkans and the Ottoman Empire, while Middle East referred to Iran, the Caucasus, Afghanistan, Central Asia, and Turkestan. The first official use of the term Middle East by the United States government was in the 1957 Eisenhower Doctrine, the Associated Press Stylebook says that Near East formerly referred to the farther west countries while Middle East referred to the eastern ones, but that now they are synonymous

Yellow River
–
The Yellow River or Huang He is the second-longest river in Asia, following the Yangtze River, and the sixth-longest river system in the world at the estimated length of 5,464 km. Originating in the Bayan Har Mountains in Qinghai province of western China, it flows through nine provinces, the Yellow River basin has an east–west extent of about 1,900 kilometers and a north–south extent of about 1,100 km. Its total basin area is about 742,443 square kilometers and its basin was the birthplace of ancient Chinese civilization, and it was the most prosperous region in early Chinese history. Early Chinese literature including the Yu Gong or Tribute of Yu dating to the Warring States period refers to the Yellow River as simply 河, the first appearance of the name 黃河 is in the Book of Han written during the Eastern Han dynasty about the Western Han dynasty. The adjective yellow describes the color of the muddy water in the lower course of the river. One of its older Mongolian names was the Black River, because the river runs clear before it enters the Loess Plateau, in Mongolia itself, it is simply called the Šar Mörön. In Qinghai, the rivers Tibetan name is River of the Peacock above sea level they are the two largest plateau freshwater lakes nationwide, flowing east at the eastern edge of the Amne Machin Mountains, the Yellow River enters Maqu County in Gansu. Here, the river skirts through the peat bog known as the Zoigê Wetlands. Flowing now along the edge of Amne Machin, the river reenters Qinghai. The valley section stretches from Longyang Gorge in Qinghai to Qingtong Gorge in Gansu, steep cliffs line both sides of the river. The water bed is narrow and the drop is large, so the flow in this section is extremely turbulent. There are 20 gorges in this section, the most famous of these being the Longyang, Jishi, Liujia, Bapan, the flow conditions in this section makes it the best location for hydroelectric plants. The Yellow River exits Qinghai for the second and final time in these gorges, downstream from the Yanguo Gorge, the provincial capital of Lanzhou is built upon the Yellow Rivers banks. The Yellow River flows northeasterly out of Gansu and into Ningxia before the Qingtong Gorge, after emerging from the Qingtong Gorge, the river comes into a section of vast alluvial plains, the Yinchuan Plain and Hetao Plain. In this section, the regions along the river are mostly deserts and grasslands, the Hetao Plain has a length of 900 km and width of 30 to 50 km. It is historically the most important irrigation plain along the Yellow River, the Ordos Loop formed by an enormous twist of the Yellow River, beginning at Zhongning County in Ningxia and ending with a drastic eastward turn at its confluence with the Wei at Tongguan in Shaanxi. However, the division for the middle reaches of the river run from Hekou in Togtoh County, Inner Mongolia, to Zhengzhou. The middle reaches are 1,206 km long, with an area of 344,000 square kilometers,45. 7% of the total, with a total elevation drop of 890 m

Yangtze
–
The Yangtze River, known in China as the Cháng Jiāng or the Yángzǐ Jiāng, is the longest river in Asia and the third-longest in the world. The river is the longest in the world to flow entirely within one country and it drains one-fifth of the land area of the Peoples Republic of China and its river basin is home to one-third of the countrys population. The Yangtze is the sixth-largest river by volume in the world. The Yangtze River plays a role in the history, culture. The prosperous Yangtze River Delta generates as much as 20% of the PRCs GDP, for thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking and war. The Three Gorges Dam on the Yangtze River is the largest hydro-electric power station in the world, in recent years, the river has suffered from industrial pollution, agricultural run-off, siltation, and loss of wetland and lakes, which exacerbates seasonal flooding. Some sections of the river are now protected as nature reserves, a stretch of the upstream Yangtze flowing through deep gorges in western Yunnan is part of the Three Parallel Rivers of Yunnan Protected Areas, a UNESCO World Heritage Site. In mid-2014 the Chinese government announced it was building a transport network, comprising railways, roads and airports. Because the source of the Yangtze was not ascertained until modern times, Yangtze was actually the name of Chang Jiang for the lower part from Nanjing to the river mouth at Shanghai. In modern Chinese, Yangtze is still used to refer to the part of Chang Jiang from Nanjing to the river mouth. Yangtze never stands for the whole Chang Jiang, Chang Jiang is the modern Chinese name for the lower 2,884 km of the Yangtze from its confluence with the Min River at Yibin in Sichuan Province to the river mouth at Shanghai. Chang Jiang literally means the Long River, in Old Chinese, this stretch of the Yangtze was simply called Jiang/Kiang 江, a character of phono-semantic compound origin, combining the water radical 氵 with the homophone 工. Krong was probably a word in the Austroasiatic language of local peoples such as the Yue, similar to *krong in Proto-Vietnamese and krung in Mon, all meaning river, it is related to modern Vietnamese sông and Khmer kôngkea. By the Han Dynasty, Jiang had come to any river in Chinese. The epithet 長, means long, was first formally applied to the river during the Six Dynasties period, various sections of Chang Jiang have local names. From Yibin to Yichang, the river through Sichuan and Chongqing Municipality is also known as the Chuan Jiang or Sichuan River, in the Hubei Province, the river is also called the Jing Jiang or the Jing River after Jingzhou. In Anhui Province, the takes on the local name Wan Jiang after the shorthand name for Anhui. And Yangzi Jiang t 揚子江s 扬子江, p Yángzǐjiāng) or the Yangzi River, the name likely comes from an ancient ferry crossing called Yangzi or Yangzijin

Pengtoushan
–
The Pengtoushan culture, dating 7500–6100 BC, was a Neolithic culture centered primarily around the central Yangtze River region in northwestern Hunan, China. It was roughly contemporaneous with its neighbor, the Peiligang culture. The two primary examples of Pengtoushan culture are the site at Pengtoushan and the later site at Bashidang. The type site at Pengtoushan was discovered in Li County, Hunan and this site is the earliest permanently settled village yet discovered in China. Excavated in 1988, Pengtoushan has been difficult to date accurately, cord-marked pottery was discovered among the burial goods. Analysis of Chinese rice residues which were Carbon-14 dated to 8200-7800 BC show that rice had been domesticated by this time, the size of the Pengtoushan rice was larger than the size of naturally occurring wild rice, however, Pengtoushan lacked evidence of tools used in cultivating rice. Although not found at Pengtoushan, rice-cultivating tools were found in sites associated with the Pengtoushan culture. List of Neolithic cultures of China Daxi culture Qujialing culture

South America
–
South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It may also be considered a subcontinent of the Americas, which is the used in nations that speak Romance languages. The reference to South America instead of other regions has increased in the last decades due to changing geopolitical dynamics. It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean, North America and it includes twelve sovereign states, a part of France, and a non-sovereign area. In addition to this, the ABC islands of the Kingdom of the Netherlands, Trinidad and Tobago, South America has an area of 17,840,000 square kilometers. Its population as of 2005 has been estimated at more than 371,090,000, South America ranks fourth in area and fifth in population. Brazil is by far the most populous South American country, with more than half of the population, followed by Colombia, Argentina, Venezuela. In recent decades Brazil has also concentrated half of the regions GDP and has become a first regional power, most of the population lives near the continents western or eastern coasts while the interior and the far south are sparsely populated. Most of the continent lies in the tropics, the continents cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the majority of South Americans speak Portuguese or Spanish. South America occupies the portion of the Americas. The continent is delimited on the northwest by the Darién watershed along the Colombia–Panama border. Almost all of mainland South America sits on the South American Plate, South Americas major mineral resources are gold, silver, copper, iron ore, tin, and petroleum. These resources found in South America have brought high income to its countries especially in times of war or of rapid growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity often has hindered the development of diversified economies and this is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export. South America is one of the most biodiverse continents on earth, South America is home to many interesting and unique species of animals including the llama, anaconda, piranha, jaguar, vicuña, and tapir. The Amazon rainforests possess high biodiversity, containing a proportion of the Earths species. Brazil is the largest country in South America, encompassing around half of the land area

Norte Chico civilization
–
The Norte Chico civilization was a complex pre-Columbian era society that included as many as 30 major population centers in what is now the Norte Chico region of north-central coastal Peru. The civilization flourished between the fourth and second millennia BC, with the formation of the first city generally dated to around 3500 BC, at Huaricanga, in the Fortaleza area. It is from 3200 BC onward that large-scale human settlement and communal construction become clearly apparent, since the early 21st century, it has been established as the oldest known civilization in the Americas. This civilization flourished at the confluence of three rivers, the Fortaleza, the Pativilca, and the Supe and these river valleys each have large clusters of sites. Further south, there are several associated sites along the Huaura River, the alternative name, Caral-Supe, is derived from the city of Caral in the Supe Valley, a large and well-studied Norte Chico site. Complex society in Norte Chico arose a millennium after Sumer in Mesopotamia, was contemporaneous with the Egyptian pyramids, in archaeological nomenclature, Norte Chico is a pre-ceramic culture of the pre-Columbian Late Archaic, it completely lacked ceramics and apparently had almost no visual art. The most impressive achievement of the civilization was its monumental architecture, including earthwork platform mounds. Archaeological evidence suggests use of technology and, possibly, the worship of common god symbols. Sophisticated government is assumed to have required to manage the ancient Norte Chico. Questions remain over its organization, particularly the influence of food resources on politics, in the late 1990s Peruvian archaeologists, led by Ruth Shady, provided the first extensive documentation of the civilization with work at Caral. Norte Chico has pushed back the horizon for complex societies in the Peruvian region by more than one thousand years, the Chavín culture, circa 900 BC, had long been considered the first civilization of the area. It is still cited as such in general works. The discovery of Norte Chico has also shifted the focus of research away from the areas of the Andes and lowlands adjacent to the mountains to the Peruvian littoral. Norte Chico is located in a area of the coast, approximately 150 to 200 km north of Lima, roughly bounded by the Lurín Valley on the south. It comprises four coastal valleys, the Huaura, Supe, Pativilca, the three principal valleys cover only 1,800 km², and research has emphasized the density of the population centers. The Peruvian littoral appears an improbable, even aberrant candidate for the development of civilization. It is extremely arid, bounded by two rain shadows, the region is punctuated by more than 50 rivers that carry Andean snowmelt. The radiocarbon work of Jonathan Haas et al, two dates of 3700 BC are associated with communal architecture, but are likely to be anomalous

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

Mesopotamia
–
In the Iron Age, it was controlled by the Neo-Assyrian and Neo-Babylonian Empires. The Sumerians and Akkadians dominated Mesopotamia from the beginning of history to the fall of Babylon in 539 BC. It fell to Alexander the Great in 332 BC, and after his death, around 150 BC, Mesopotamia was under the control of the Parthian Empire. Mesopotamia became a battleground between the Romans and Parthians, with parts of Mesopotamia coming under ephemeral Roman control. In AD226, eastern part of it fell to the Sassanid Persians, division of Mesopotamia between Roman and Sassanid Empires lasted until the 7th century Muslim conquest of Persia of the Sasanian Empire and Muslim conquest of the Levant from Byzantines. A number of primarily neo-Assyrian and Christian native Mesopotamian states existed between the 1st century BC and 3rd century AD, including Adiabene, Osroene, and Hatra, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. The regional toponym Mesopotamia comes from the ancient Greek root words μέσος middle and ποταμός river and it is used throughout the Greek Septuagint to translate the Hebrew equivalent Naharaim. In the Anabasis, Mesopotamia was used to designate the land east of the Euphrates in north Syria, the Aramaic term biritum/birit narim corresponded to a similar geographical concept. The neighbouring steppes to the west of the Euphrates and the part of the Zagros Mountains are also often included under the wider term Mesopotamia. A further distinction is made between Northern or Upper Mesopotamia and Southern or Lower Mesopotamia. Upper Mesopotamia, also known as the Jazira, is the area between the Euphrates and the Tigris from their sources down to Baghdad, Lower Mesopotamia is the area from Baghdad to the Persian Gulf and includes Kuwait and parts of western Iran. In modern academic usage, the term Mesopotamia often also has a chronological connotation and it is usually used to designate the area until the Muslim conquests, with names like Syria, Jazirah, and Iraq being used to describe the region after that date. It has been argued that these later euphemisms are Eurocentric terms attributed to the region in the midst of various 19th-century Western encroachments, Mesopotamia encompasses the land between the Euphrates and Tigris rivers, both of which have their headwaters in the Armenian Highlands. Both rivers are fed by tributaries, and the entire river system drains a vast mountainous region. Overland routes in Mesopotamia usually follow the Euphrates because the banks of the Tigris are frequently steep and difficult. The climate of the region is semi-arid with a vast desert expanse in the north which gives way to a 15,000 square kilometres region of marshes, lagoons, mud flats, in the extreme south, the Euphrates and the Tigris unite and empty into the Persian Gulf. In the marshlands to the south of the area, a complex water-borne fishing culture has existed since prehistoric times, periodic breakdowns in the cultural system have occurred for a number of reasons. Alternatively, military vulnerability to invasion from marginal hill tribes or nomadic pastoralists has led to periods of trade collapse and these trends have continued to the present day in Iraq

History of the world
–
The history of the world describes the history of humanity as determined by the study of archaeological and written records, beginning with the invention of writing. The latter period marked a change in history, as humans began the systematic husbandry of plants. Agriculture advanced, and most humans transitioned from a nomadic to a lifestyle as farmers in permanent settlements. As farming developed, grain agriculture became more sophisticated and prompted a division of labour to store food between growing seasons, labour divisions then led to the rise of a leisured upper class and the development of cities. The growing complexity of human societies necessitated systems of writing and accounting, in the mid-15th century, the invention of modern printing, employing movable type, revolutionized communication, helping end the Middle Ages and ushering in the Scientific Revolution. By the 18th century, the accumulation of knowledge and technology, outside the Old World, including ancient China and ancient India, historical timelines unfolded differently. However, by the 18th century, due to world trade and colonization. Genetic measurements indicate that the ape lineage which would lead to Homo sapiens diverged from the lineage that would lead to chimpanzees around six years ago. It is thought that the Australopithecine genus, which were likely the first apes to walk upright, anatomically modern humans arose in Africa about 200,000 years ago, and reached behavioural modernity about 50,000 years ago. Modern humans spread rapidly from Africa into the frost-free zones of Europe, the rapid expansion of humankind to North America and Oceania took place at the climax of the most recent ice age, when temperate regions of today were extremely inhospitable. Yet, humans had colonized nearly all the parts of the globe by the end of the Ice Age. Other hominids such as Homo erectus had been using simple wood and stone tools for millennia, at some point, humans began using fire for heat and cooking. They also developed language in the Palaeolithic period and a repertoire that included systematic burial of the dead. Early artistic expression can be found in the form of paintings and sculptures made from wood and bone, showing a spirituality generally interpreted as animism. During this period, all lived as hunter-gatherers, and were generally nomadic. The Neolithic Revolution, beginning about 8,000 BCE, saw the development of agriculture, Mesopotamia is the site of the earliest developments of the Neolithic Revolution. Farming permitted far denser populations, which in time organized into states, agriculture also created food surpluses that could support people not directly engaged in food production. The development of agriculture permitted the creation of the first cities and these were centres of trade, manufacturing and political power with nearly no agricultural production of their own

Wheel
–
A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the components of the wheel. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, wheels are also used for other purposes, such as a ships wheel, steering wheel, potters wheel and flywheel. Common examples are found in transport applications, a wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, cognates within Indo-European include Icelandic hjól wheel, tyre, Greek κύκλος kúklos, and Sanskrit chakra, the latter both meaning circle or wheel. The invention of the falls into the late Neolithic. Note that this implies the passage of several wheel-less millennia even after the invention of agriculture and of pottery, precursors of wheels, known as tournettes or slow wheels, were known in the Middle East by the 5th millennium BCE. These were made of stone or clay and secured to the ground with a peg in the center, but required effort to turn. True potters wheels were apparently in use in Mesopotamia by 3500 BCE and possibly as early as 4000 BCE, and the oldest surviving example, which was found in Ur, dates to approximately 3100 BCE. The earliest well-dated depiction of a vehicle is on the Bronocice pot. The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia is now dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE. Two types of early Neolithic European wheel and axle are known, a type of wagon construction. They both are dated to c, in China, the wheel was certainly present with the adoption of the chariot in c.1200 BCE, although Barbieri-Low argues for earlier Chinese wheeled vehicles, c.2000 BC. In Britain, a wooden wheel, measuring about 1 m in diameter, was uncovered at the Must Farm site in East Anglia in 2016. The specimen, dating from 1, 100–800 years BCE, represents the most complete, the wheels hub is also present. A horses spine found nearby suggests the wheel may have part of a horse-drawn cart. The wheel was found in a settlement built on stilts over wetland and it is thought that the primary obstacle to large-scale development of the wheel in the Americas was the absence of domesticated large animals which could be used to pull wheeled carriages. The only large animal that was domesticated in the Western hemisphere, Nubians from after about 400 BCE used wheels for spinning pottery and as water wheels
31.
Cursive
–
Cursive, is any style of penmanship in which some characters are written joined together in a flowing manner, generally for the purpose of making writing faster. Formal cursive is generally joined, but casual cursive is a combination of joins, the writing style can be further divided as looped, italic, or connected. The cursive method is used with a number of alphabets due to its improved writing speed, in some alphabets, many or all letters in a word are connected sometimes making a word two single complex strokes. Cursive is any style of penmanship in which the symbols of the language are written in a conjoined and/or flowing manner and this writing style is distinct from printscript using block letters, in which the letters of a word are unconnected and in Roman/Gothic letterform rather than joined-up script. Not all cursive copybooks join all letters, formal cursive is generally joined, in the Arabic, Syriac, Latin, and Cyrillic alphabets, many or all letters in a word are connected, sometimes making a word one single complex stroke. In Hebrew cursive and Roman cursive, the letters are not connected, in Maharashtra there is a version of Cursive called Modi In looped cursive penmanship, some ascenders and descenders have loops which provide for joins. Cursive italic penmanship—derived from chancery cursive—uses non-looped joins or no joins, in italic cursive, there are no joins from g, j, q or y, and a few other joins are discouraged. Italic penmanship became popular in the 15th-century Italian Renaissance, the term italic as it relates to handwriting is not to be confused with italic typed letters that slant forward. Many, but not all, letters in the handwriting of the Renaissance were joined, the origins of the cursive method is associated with practical advantages of writing speed and infrequent pen lifting to accommodate the limitations of the quill. Quills are fragile, easily broken, and will spatter unless used properly, steel dip pens followed quills, they were sturdier, but still had some limitations. The individuality of the provenance of a document was a factor also, the term cursive derives from the 18th century Italian corsivo from Medieval Latin cursivus, which literally means running. This term in turn derives from Latin currere, Modi is a script used to write the Marathi language, which is the primary language spoken in the state of Maharashtra, India. There are at least two different theories concerning its origin, modI was an official script used to write Marathi until the 20th century when the Balbodh style of the Devanagari script was promoted as the standard writing system for Marathi. Although Modi was primarily used to write Marathi, other such as Urdu, Kannada, Gujarati, Rajasthani, Hindi. In Bengali cursive script the letters are more likely to be more curvy in appearance than in standard Bengali handwriting, also, the horizontal supporting bar on each letter runs continuously through the entire word, unlike in standard handwriting. Roman cursive is a form of handwriting used in ancient Rome and it is customarily divided into old cursive, and new cursive. New Roman cursive, also called minuscule cursive or later Roman cursive, the Greek alphabet has had several cursive forms in the course of its development. In antiquity, a form of handwriting was used in writing on papyrus

Mathematics
–
Mathematics is the study of topics such as quantity, structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope, Mathematicians seek out patterns and use them to formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proof, when mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry, rigorous arguments first appeared in Greek mathematics, most notably in Euclids Elements. Galileo Galilei said, The universe cannot be read until we have learned the language and it is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word. Without these, one is wandering about in a dark labyrinth, carl Friedrich Gauss referred to mathematics as the Queen of the Sciences. Benjamin Peirce called mathematics the science that draws necessary conclusions, David Hilbert said of mathematics, We are not speaking here of arbitrariness in any sense. Mathematics is not like a game whose tasks are determined by arbitrarily stipulated rules, rather, it is a conceptual system possessing internal necessity that can only be so and by no means otherwise. Albert Einstein stated that as far as the laws of mathematics refer to reality, they are not certain, Mathematics is essential in many fields, including natural science, engineering, medicine, finance and the social sciences. Applied mathematics has led to entirely new mathematical disciplines, such as statistics, Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind. There is no clear line separating pure and applied mathematics, the history of mathematics can be seen as an ever-increasing series of abstractions. The earliest uses of mathematics were in trading, land measurement, painting and weaving patterns, in Babylonian mathematics elementary arithmetic first appears in the archaeological record. Numeracy pre-dated writing and numeral systems have many and diverse. Between 600 and 300 BC the Ancient Greeks began a study of mathematics in its own right with Greek mathematics. Mathematics has since been extended, and there has been a fruitful interaction between mathematics and science, to the benefit of both. Mathematical discoveries continue to be made today, the overwhelming majority of works in this ocean contain new mathematical theorems and their proofs. The word máthēma is derived from μανθάνω, while the modern Greek equivalent is μαθαίνω, in Greece, the word for mathematics came to have the narrower and more technical meaning mathematical study even in Classical times
33.
Astronomy
–
Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets, while the phenomena include supernovae explosions, gamma ray bursts, more generally, all astronomical phenomena that originate outside Earths atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole, Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, during the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the results and observations being used to confirm theoretical results. Astronomy is one of the few sciences where amateurs can play an active role, especially in the discovery. Amateur astronomers have made and contributed to many important astronomical discoveries, Astronomy means law of the stars. Astronomy should not be confused with astrology, the system which claims that human affairs are correlated with the positions of celestial objects. Although the two share a common origin, they are now entirely distinct. Generally, either the term astronomy or astrophysics may be used to refer to this subject, however, since most modern astronomical research deals with subjects related to physics, modern astronomy could actually be called astrophysics. Few fields, such as astrometry, are purely astronomy rather than also astrophysics, some titles of the leading scientific journals in this field includeThe Astronomical Journal, The Astrophysical Journal and Astronomy and Astrophysics. In early times, astronomy only comprised the observation and predictions of the motions of objects visible to the naked eye, in some locations, early cultures assembled massive artifacts that possibly had some astronomical purpose. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye, most of early astronomy actually consisted of mapping the positions of the stars and planets, a science now referred to as astrometry. From these observations, early ideas about the motions of the planets were formed, and the nature of the Sun, Moon, the Earth was believed to be the center of the Universe with the Sun, the Moon and the stars rotating around it. This is known as the model of the Universe, or the Ptolemaic system. The Babylonians discovered that lunar eclipses recurred in a cycle known as a saros

Agriculture
–
Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life. Agriculture was the key development in the rise of human civilization. The study of agriculture is known as agricultural science, the history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology, genetically modified organisms are an increasing component of agriculture, although they are banned in several countries. Agricultural food production and water management are increasingly becoming global issues that are fostering debate on a number of fronts, the major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. Specific foods include cereals, vegetables, fruits, oils, meats, fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo, other useful materials are also produced by plants, such as resins, dyes, drugs, perfumes, biofuels and ornamental products such as cut flowers and nursery plants. The word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, field, Agriculture usually refers to human activities, although it is also observed in certain species of ant, termite and ambrosia beetle. To practice agriculture means to use resources to produce commodities which maintain life, including food, fiber, forest products, horticultural crops. This definition includes arable farming or agronomy, and horticulture, all terms for the growing of plants, even then, it is acknowledged that there is a large amount of knowledge transfer and overlap between silviculture and agriculture. In traditional farming, the two are often combined even on small landholdings, leading to the term agroforestry, Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin, wild grains were collected and eaten from at least 105,000 years ago. Pigs were domesticated in Mesopotamia around 15,000 years ago, rice was domesticated in China between 13,500 and 8,200 years ago, followed by mung, soy and azuki beans. Sheep were domesticated in Mesopotamia between 13,000 and 11,000 years ago. From around 11,500 years ago, the eight Neolithic founder crops, emmer and einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Cattle were domesticated from the aurochs in the areas of modern Turkey. In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, coca, llamas, alpacas, sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago, cotton was domesticated in Peru by 5,600 years ago, and was independently domesticated in Eurasia at an unknown time
35.
Sedentism
–
In cultural anthropology, sedentism simply refers to the practice of living in one place for a long time. As of 2017 the majority of people belong to sedentary cultures, essentially, sedentism means living in groups permanently in one place. It was only in locations where the resources of several major ecosystems overlapped that the earliest non-agricultural sedentism occurred. For example, people settled where a river met the sea, at lagoon environments along the coast, at river confluences, or where flat savanna met hills, and mountains with rivers. Sedentism usually meant more people, sturdier houses, new tools, more jewelry, burials or cemeteries, more long-distance goods. At sedentary sites usually more people lived together for a time compared to earlier base camp sites or annual gathering sites. This created deeper cultural layers and thus generally richer archaeological materials, there are also indications that the use of rock art is connected to sedentism, both pre-agricultural and agricultural forms. In archaeology a number of criteria is necessary for the recognition of either semi or full sedentism, according to Israeli archaeologist Ofer Bar-Yosef, they are as follows,1. Increasing presence of organisms benefit from human sedentary activities, e. g. House mice Rats Sparrows 2. Cementum increments on mammal teeth Indications that hunting took place in winter and summer 3. In the Levant, the Natufian culture was the first to become sedentary at around 12000 BC, the Natufians were sedentary for more than 2000 years before they, at some sites, started to cultivate plants around 10000 BC. The Jōmon culture in Japan, which was primarily a coastal culture, was sedentary from c.12000 to 10000 BC, in northernmost Scandinavia, there are several early sedentary sites without evidence of agriculture or cattle breeding. 5300-4500 BC and are all located optimally in the landscape for extraction of major resources, e. g. the Lillberget Stone Age village site, the Nyelv site. In northern Sweden the earliest indication of agriculture occurs at previously sedentary sites, 2700-1700 BC, famous for its large caches of long distance traded flint axes from Denmark and Scania. The evidence of agriculture at that site can be seen from c.2300 BC. Not all contemporary sites during a period were sedentary. Evaluation of habitational sites in northern Sweden indicates that less than 10 percent of all the sites around 4000 BC, were sedentary, at the same time, only 0. 5-1 percent of these represented villages with more than 3-4 houses. The shift to sedentism is coupled with the adoption of new subsistence strategies, the development of sedentism led to the rise of population aggregation and formation of villages, cities, and other community types
36.
Economies of scale
–
Often operational efficiency is also greater with increasing scale, leading to lower variable cost as well. Economies of scale apply to a variety of organizational and business situations and at levels, such as a business or manufacturing unit. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation, the economic concept dates back to Adam Smith and the idea of obtaining larger production returns through the use of division of labor. Diseconomies of scale are the opposite, Economies of scale often have limits, such as passing the optimum design point where costs per additional unit begin to increase. Common limits include exceeding the nearby raw material supply, such as wood in the lumber, pulp, a common limit for low cost per unit weight commodities is saturating the regional market, thus having to ship product uneconomical distances. Other limits include using energy less efficiently or having a defect rate. Large producers are usually efficient at long runs of a product grade and they will therefore avoid specialty grades even though they have higher margins. Often smaller manufacturing facilities remain viable by changing from commodity grade production to specialty products, the simple meaning of economies of scale is doing things more efficiently with increasing size or speed of operation. Economies of scale often originate with fixed capital, which is lowered per unit of production as design capacity increases, in wholesale and retail distribution, increasing the speed of operations, such as order fulfillment, lowers the cost of both fixed and working capital. Other common sources of economies of scale are purchasing, managerial, financial, marketing, each of these factors reduces the long run average costs of production by shifting the short-run average total cost curve down and to the right. Economies of the scale is a concept that may explain real world phenomena such as patterns of international trade or the number of firms in a market. The exploitation of economies of scale helps explain why companies grow large in some industries, a lone car maker may be profitable, but even more so if they exported cars to global markets in addition to selling to the local market. Economies of scale play a role in a natural monopoly. There is a distinction between two types of economies of scale, internal and external, conversely, an industry exhibits an external economy of scale when costs drop due to the introduction of more firms, thus allowing for more efficient use of specialized services and machinery. Instead, he believes that economies will come from improving the flow of a service, in trying to manage and reduce unit costs, firms often raise total costs by creating failure demand. This law has an effect on the capital cost of such things as buildings, factories, pipelines, ships. In structural engineering, the strength of beams increases with the cube of the thickness, drag loss of vehicles like aircraft or ships generally increases less than proportional with increasing cargo volume, although the physical details can be quite complicated. Therefore, making them larger usually results in fuel consumption per ton of cargo at a given speed
37.
Chalcolithic
–
The Copper Age was originally defined as a transition between the Neolithic and the Bronze Age. The archaeological site of Belovode on the Rudnik mountain in Serbia contains the worlds oldest securely dated evidence of copper smelting from 5000 BCE, the multiple names result from multiple recognitions of the period. Originally, the term Bronze Age meant that either copper or bronze was being used as the hard substance for the manufacture of tools. In 1881, John Evans, recognizing that the use of copper often preceded the use of bronze and he did not include the transitional period in the tripartite system of Early, Middle and Late Bronze Age but placed it at the beginning outside of it. He did not, however, present it as a fourth age, in 1884, Gaetano Chierici, perhaps following the lead of Evans, renamed it in Italian as the Eneo-litica, or Bronze-stone transition. The phrase was never intended to mean that the period was the one in which both bronze and stone were used. The Copper Age features the use of copper, excluding bronze, moreover, litica simply names the Stone Age as the point from which the transition began and is not another -lithic age. Subsequently, British scholars used either Evanss Copper Age or the term Eneolithic, around 1900, many writers began to substitute Chalcolithic for Eneolithic, to avoid the false segmentation. It was then that the misunderstanding began among those who did not know Italian, the -lithic was seen as a new -lithic age, a part of the Stone Age in which copper was used, which may appear paradoxical. Today Copper Age, Eneolithic and Chalcolithic are used synonymously to mean Evanss original definition of Copper Age, there was an independent invention of copper and bronze smelting first by Andean civilizations in South America extended later by sea commerce to the Mesoamerican civilization in West Mexico. The literature of European archaeology, in general, avoids the use of Chalcolithic, the Copper Age in the Middle East and the Caucasus began in the late 5th millennium BCE and lasted for about a millennium before it gave rise to the Early Bronze Age. The transition from the European Copper Age to Bronze Age Europe occurs about the same time, an archaeological site in Serbia contains the oldest securely dated evidence of coppermaking from 7,500 years ago. In Serbia, an axe was found at Prokuplje, which indicates that humans were using metals in Europe by 7,500 years ago. Knowledge of the use of copper was far more widespread than the metal itself, the European Battle Axe culture used stone axes modeled on copper axes, even with imitation mold marks carved in the stone. Ötzi the Iceman, who was found in the Ötztal Alps in 1991, examples of Chalcolithic cultures in Europe include Vila Nova de São Pedro and Los Millares on the Iberian Peninsula. Pottery of the Beaker people has found at both sites, dating to several centuries after copper-working began there. The Beaker culture appears to have copper and bronze technologies in Europe. The term Chalcolithic is not generally used by British prehistorians, who disagree whether it applies in the British context, in Bhirrana, the earliest Indus civilization site, copper bangles and arrowheads were found
38.
Cradle of civilisation
–
The cradle of civilization is a term referring to locations where, according to current archaeological data, civilization is understood to have emerged. Current thinking is that there was no single cradle, but several civilizations that developed independently, other civilizations arose in Asia among cultures situated along large river valleys, notably the Indus River in the Indian Subcontinent and the Yellow River in China. The extent to which there was significant influence between the early civilizations of the Near East and those of East Asia is disputed, scholars accept that the civilizations of Mesoamerica, mainly in modern Mexico, and Norte Chico in present-day Peru emerged independently from those in Eurasia. The concept cradle of civilization is the subject of much debate, the figurative use of cradle to mean the place or region in which anything is nurtured or sheltered in its earlier stage is traced by the OED to Spenser. Charles Rollins Ancient History has Egypt that served at first as the cradle of the holy nation, the phrase cradle of civilization plays a certain role in national mysticism. It has been used in Eastern as well as Western cultures, for instance, in Hindu nationalism, the terms also appear in esoteric pseudohistory, such as the Urantia Book, claiming the title for the second Eden, or the pseudoarchaeology related to Megalithic Britain. The earliest proto-urban settlements with several thousand inhabitants emerged in the Neolithic, the first cities to house several tens of thousands were Memphis and Uruk, by the 31st century BCE. Historic times are marked apart from times when records of the past begin to be kept for the benefit of future generations. A civilized way of life is linked to conditions coming almost exclusively from intensive agriculture. A traditional theory of the spread of civilization is that it began in the Fertile Crescent, scholars more generally now believe that civilizations arose independently at several locations in both hemispheres. They have observed that sociocultural developments occurred along different timeframes, sedentary and nomadic communities continued to interact considerably, they were not strictly divided among widely different cultural groups. Current scholarship generally identifies six sites where civilization emerged independently, Mesopotamia, the Nile River, the Indus River, the Yellow River, the Central Andes, one of the most notable PPNA settlements is Jericho in the Levant region, thought to be the worlds first town. In Mesopotamia, the convergence of the Tigris and Euphrates rivers produced rich fertile soil, the civilizations that emerged around these rivers are among the earliest known non-nomadic agrarian societies. It is because of this that the fertile crescent region, the period known as the Ubaid period is the earliest known period on the alluvial plain although it is likely earlier periods exist obscured under the alluvium. It was during the Ubaid period that the movement towards urbanization began, eridu is the oldest Sumerian site settled during this period, around 5300 BCE, and the city of Ur also first dates to the end of this period. In the south, the Ubaid period had a long duration from around 6500 to 3800 BCE. Named after the Sumerian city of Uruk, this saw the emergence of urban life in Mesopotamia and, during its later phase. Proto-writing in the dates to around 3500 BCE, with the earliest texts dating to 3300 BCE
39.
Pre-Columbian Americas
–
For this reason the alternative terms of Precontact Americas, Pre-Colonial Americas or Prehistoric Americas are also in use. In areas of Latin America the term used is Pre-Hispanic. Other civilizations were contemporary with the period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own written records, because many Christian Europeans of the time viewed such texts as heretical, men like Diego de Landa destroyed many texts in pyres, even while seeking to preserve native histories. Only a few documents have survived in their original languages, while others were transcribed or dictated into Spanish, giving modern historians glimpses of ancient culture. Indigenous American cultures continue to evolve after the pre-Columbian era, many of these peoples and their descendants continue traditional practices, while evolving and adapting new cultural practices and technologies into their lives. Now, the study of pre-Columbian cultures is most often based on scientific. Asian nomads are thought to have entered the Americas via the Bering Land Bridge, now the Bering Strait, genetic evidence found in Amerindians maternally inherited mitochondrial DNA supports the theory of multiple genetic populations migrating from Asia. Over the course of millennia, Paleo-Indians spread throughout North and South America, exactly when the first group of people migrated into the Americas is the subject of much debate. One of the earliest identifiable cultures was the Clovis culture, with sites dating from some 13,000 years ago, however, older sites dating back to 20,000 years ago have been claimed. Some genetic studies estimate the colonization of the Americas dates from between 40,000 and 13,000 years ago, the chronology of migration models is currently divided into two general approaches. The first is the short chronology theory with the first movement beyond Alaska into the New World occurring no earlier than 14, 000–17,000 years ago, followed by successive waves of immigrants. The second belief is the long chronology theory, which proposes that the first group of people entered the hemisphere at an earlier date, possibly 50. In that case, the Eskimo peoples would have arrived separately and at a later date, probably no more than 2,000 years ago. The North American climate was unstable as the ice age receded and it finally stabilized by about 10,000 years ago, climatic conditions were then very similar to todays.
