Guns, Germs, and Steel: The Fates of Human Societies (also titled Guns, Germs and Steel: A short history of everybody for the last 13,000 years) is a 1997 transdisciplinary non-fiction book by Jared Diamond, professor of geography and physiology at the University of California, Los Angeles (UCLA). In 1998, Guns, Germs, and Steel won the Pulitzer Prize for general nonfiction and the Aventis Prize for Best Science Book. A documentary based on the book, and produced by the National Geographic Society, was broadcast on PBS in July 2005.

The book attempts to explain why Eurasian and North African civilizations have survived and conquered others, while arguing against the idea that Eurasian hegemony is due to any form of Eurasian intellectual, moral, or inherent genetic superiority. Diamond argues that the gaps in power and technology between human societies originate primarily in environmental differences, which are amplified by various positive feedback loops. When cultural or genetic differences have favored Eurasians (for example, written language or the development among Eurasians of resistance to endemic diseases), he asserts that these advantages occurred because of the influence of geography on societies and cultures (for example, by facilitating commerce and trade between different cultures) and were not inherent in the Eurasian genomes.

Synopsis

The prologue opens with an account of Diamond's conversation with Yali, a New Guinean politician. The conversation turned to the obvious differences in power and technology between Yali's people and the Europeans who dominated the land for 200 years, differences that neither of them considered due to any genetic superiority of Europeans. Yali asked, using the local term "cargo" for inventions and manufactured goods, "Why is it that you white people developed so much cargo and brought it to New Guinea, but we black people had little cargo of our own?" (p. 14)

Diamond realized the same question seemed to apply elsewhere: "People of Eurasian origin ... dominate ... the world in wealth and power." Other peoples, after having thrown off colonial domination, still lag in wealth and power. Still others, he says, "have been decimated, subjugated, and in some cases even exterminated by European colonialists." (p. 15)

The peoples of other continents (sub-Saharan Africans, Native Americans, Aboriginal Australians and New Guineans, and the original inhabitants of tropical Southeast Asia) have been largely conquered, displaced and in some extreme cases – referring to Native Americans, Aboriginal Australians, and South Africa's indigenous Khoisan peoples – largely exterminated by farm-based societies such as Eurasians and Bantu. He believes this is due to these societies' technologic and immunologic advantages, stemming from the early rise of agriculture after the last Ice Age.

Title

The book's title is a reference to the means by which farm-based societies conquered populations of other areas and maintained dominance, despite sometimes being vastly outnumbered – superior weapons provided immediate military superiority (guns); Eurasian diseases weakened and reduced local populations, who had no immunity, making it easier to maintain control over them (germs); and durable means of transport (steel) enabled imperialism.

Diamond argues geographic, climatic and environmental characteristics which favored early development of stable agricultural societies ultimately led to immunity to diseases endemic in agricultural animals and the development of powerful, organized states capable of dominating others.

Outline of theory

Diamond argues that Eurasian civilization is not so much a product of ingenuity, but of opportunity and necessity. That is, civilization is not created out of superior intelligence, but is the result of a chain of developments, each made possible by certain preconditions.

The first step towards civilization is the move from nomadic hunter-gatherer to rooted agrarian society. Several conditions are necessary for this transition to occur: access to high-carbohydrate vegetation that endures storage; a climate dry enough to allow storage; and access to animals docile enough for domestication and versatile enough to survive captivity. Control of crops and livestock leads to food surpluses. Surpluses free people to specialize in activities other than sustenance and support population growth. The combination of specialization and population growth leads to the accumulation of social and technologic innovations which build on each other. Large societies develop ruling classes and supporting bureaucracies, which in turn lead to the organization of nation-states and empires.

Although agriculture arose in several parts of the world, Eurasia gained an early advantage due to the greater availability of suitable plant and animal species for domestication. In particular, Eurasia has barley, two varieties of wheat, and three protein-rich pulses for food; flax for textiles; and goats, sheep, and cattle. Eurasian grains were richer in protein, easier to sow, and easier to store than American maize or tropical bananas.

As early Western Asian civilizations began to trade, they found additional useful animals in adjacent territories, most notably horses and donkeys for use in transport. Diamond identifies 13 species of large animals over 100 pounds (45 kg) domesticated in Eurasia, compared with just one in South America (counting the llama and alpaca as breeds within the same species) and none at all in the rest of the world. Australia and North America suffered from a lack of useful animals due to extinction, probably by human hunting, shortly after the end of the Pleistocene, whilst the only domesticated animals in New Guinea came from the East Asian mainland during the Austronesian settlement some 4,000–5,000 years ago. Sub-Saharan biological relatives of the horse including zebras and onagers proved untameable; and although African elephants can be tamed, it is very difficult to breed them in captivity; Diamond describes the small number of domesticated species (14 out of 148 "candidates") as an instance of the Anna Karenina principle: many promising species have just one of several significant difficulties that prevent domestication. He also makes the intriguing argument that all large mammals that could be domesticated, have been.

Eurasians domesticated goats and sheep for hides, clothing, and cheese; cows for milk; bullocks for tillage of fields and transport; and benign animals such as pigs and chickens. Large domestic animals such as horses and camels offered the considerable military and economic advantages of mobile transport.

Continental axes according to Jared Diamond in Guns, Germs, and Steel.

Eurasia's large landmass and long east-west distance increased these advantages. Its large area provided it with more plant and animal species suitable for domestication, and allowed its people to exchange both innovations and diseases. Its east-west orientation allowed breeds domesticated in one part of the continent to be used elsewhere through similarities in climate and the cycle of seasons. The Americas had difficulty adapting crops domesticated at one latitude for use at other latitudes (and, in North America, adapting crops from one side of the Rocky Mountains to the other). Similarly, Africa was fragmented by its extreme variations in climate from north to south: crops and animals that flourished in one area never reached other areas where they could have flourished, because they could not survive the intervening environment. Europe was the ultimate beneficiary of Eurasia's east-west orientation: in the first millennium BCE, the Mediterranean areas of Europe adopted Southwestern Asia's animals, plants, and agricultural techniques; in the first millennium CE, the rest of Europe followed suit.

The plentiful supply of food and the dense populations that it supported made division of labor possible. The rise of nonfarming specialists such as craftsmen and scribes accelerated economic growth and technological progress. These economic and technological advantages eventually enabled Europeans to conquer the peoples of the other continents in recent centuries by using the guns and steel of the book's title.

Eurasia's dense populations, high levels of trade, and living in close proximity to livestock resulted in widespread transmission of diseases, including from animals to humans. Smallpox, measles, and influenza were the result of close proximity between dense populations of animals and humans. Natural selection forced Eurasians to develop immunity to a wide range of pathogens. When Europeans made contact with the Americas, European diseases (to which Americans had no immunity) ravaged the indigenous American population, rather than the other way around (the "trade" in diseases was a little more balanced in Africa and southern Asia: endemic malaria and yellow fever made these regions notorious as the "white man's grave"; and syphilis may have originated in the Americas). The European diseases – the germs of the book's title – decimated indigenous populations so that relatively small numbers of Europeans could maintain their dominance.

Diamond also proposes geographical explanations for why western European societies, rather than other Eurasian powers such as China, have been the dominant colonizers, claiming Europe's geography favored balkanization into smaller, closer, nation-states, bordered by natural barriers of mountains, rivers, and coastline. Threats posed by immediate neighbours ensured governments that suppressed economic and technological progress soon corrected their mistakes or were outcompeted relatively quickly, whilst the region's leading powers changed over time. Other advanced cultures developed in areas whose geography was conducive to large, monolithic, isolated empires, without competitors that might have forced the nation to reverse mistaken policies such as China banning the building of ocean-going ships. Western Europe also benefited from a more temperate climate than Southwestern Asia where intense agriculture ultimately damaged the environment, encouraged desertification, and hurt soil fertility.

Agriculture

Guns, Germs, and Steel argues that cities require an ample supply of food, and thus are dependent on agriculture. As farmers do the work of providing food, division of labor allows others freedom to pursue other functions, such as mining and literacy.

The crucial trap for the development of agriculture is the availability of wild edible plant species suitable for domestication. Farming arose early in the Fertile Crescent since the area had an abundance of wild wheat and pulse species that were nutritious and easy to domesticate. In contrast, American farmers had to struggle to develop corn as a useful food from its probable wild ancestor, teosinte.

Also important to the transition from hunter-gatherer to city-dwelling agrarian societies was the presence of 'large' domesticable animals, raised for meat, work, and long-distance communication. Diamond identifies a mere 14 domesticated large mammal species worldwide. The five most useful (cow, horse, sheep, goat, and pig) are all descendants of species endemic to Eurasia. Of the remaining nine, only two (the llama and alpaca both of South America) are indigenous to a land outside the temperate region of Eurasia.

Due to the Anna Karenina principle, surprisingly few animals are suitable for domestication. Diamond identifies six criteria including the animal being sufficiently docile, gregarious, willing to breed in captivity and having a social dominance hierarchy. Therefore, none of the many African mammals such as the zebra, antelope, cape buffalo, and African elephant were ever domesticated (although some can be tamed, they are not easily bred in captivity). The Holocene extinction event eliminated many of the megafauna that, had they survived, might have become candidate species, and Diamond argues that the pattern of extinction is more severe on continents where animals that had no prior experience of humans were exposed to humans who already possessed advanced hunting techniques (e.g. the Americas and Australia).

Smaller domesticable animals such as dogs, cats, chickens, and guinea pigs may be valuable in various ways to an agricultural society, but will not be adequate in themselves to sustain large-scale agrarian society. An important example is the use of larger animals such as cattle and horses in plowing land, allowing for much greater crop productivity and the ability to farm a much wider variety of land and soil types than would be possible solely by human muscle power. Large domestic animals also have an important role in the transportation of goods and people over long distances, giving the societies that possess them considerable military and economic advantages.

Geography

Diamond also argues that geography shaped human migration, not simply by making travel difficult (particularly by latitude), but by how climates affect where domesticable animals can easily travel and where crops can ideally grow easily due to the sun.

The dominant Out of Africa theory holds that modern humans developed east of the Great Rift Valley of the African continent at one time or another. The Sahara kept people from migrating north to the Fertile Crescent, until later when the Nile River valley became accommodating.

Diamond continues to describe the story of human development up to the modern era, through the rapid development of technology, and its dire consequences on hunter-gathering cultures around the world.

Diamond touches on why the dominant powers of the last 500 years have been West European rather than East Asian (especially Chinese). The Asian areas in which big civilizations arose had geographical features conducive to the formation of large, stable, isolated empires which faced no external pressure to change which led to stagnation. Europe's many natural barriers allowed the development of competing nation-states. Such competition forced the European nations to encourage innovation and avoid technological stagnation.

Germs

In the later context of the European colonization of the Americas, 95% of the indigenous populations are believed to have been killed off by diseases brought by the Europeans. Many were killed by infectious diseases such as smallpox and measles. Similar circumstances were observed in the History of Australia (1788-1850) and in History of South Africa. Aboriginal Australians and the Khoikhoi population were decimated by smallpox, measles, influenza and other diseases.

How was it then that diseases native to the American continents did not kill off Europeans? Diamond posits that the most of these diseases were only developed and sustained in large dense populations in villages and cities; he also states most epidemic diseases evolve from similar diseases of domestic animals. The combined effect of the increased population densities supported by agriculture, and of close human proximity to domesticated animals leading to animal diseases infecting humans, resulted in European societies acquiring a much richer collection of dangerous pathogens to which European people had acquired immunity through natural selection (see the Black Death and other epidemics) during a longer time than was the case for Native American hunter-gatherers and farmers.

He mentions the tropical diseases (mainly malaria) that limited European penetration into Africa as an exception. Endemic infectious diseases were also barriers to European colonisation of Southeast Asia and New Guinea.

Success and failure

Guns, Germs, and Steel focuses on why some populations succeeded. His later book, Collapse: How Societies Choose to Fail or Succeed, focuses on environmental and other factors that have caused some populations to fail. It is a cautionary book.

Intellectual background

In the 1930s, the Annales School in France undertook the study of long-term historical structures by using a synthesis of geography, history, and sociology. Scholars examined the impact of geography, climate, and land use. Although geography had been nearly eliminated as an academic discipline in the United States after the 1960s, several geography-based historical theories were published in the 1990s.

In 1991, Jared Diamond already considered the question of "why is it that the Eurasians came to dominate other cultures?" in The Third Chimpanzee: The Evolution and Future of the Human Animal (part four).

Reception

Guns, Germs, and Steel won the 1997 Phi Beta Kappa Award in Science. In 1998, it won the Pulitzer Prize for General Non-Fiction, in recognition of its powerful synthesis of many disciplines, and the Royal Society's Rhône-Poulenc Prize for Science Books. The National Geographic Society produced a documentary of the same title based on the book that was broadcast on PBS in July 2005.

Academic reviews

In a review of Guns, Germs, and Steel that ultimately commended the book, historian Tom Tomlinson wrote, "Given the magnitude of the task he has set himself, it is inevitable that Professor Diamond uses very broad brush-strokes to fill in his argument."

Another historian, professor J. R. McNeill, was on the whole complimentary, but thought Diamond oversold geography as an explanation for history and underemphasized cultural autonomy.

In his last book published in 2000, the anthropologist and geographer James Morris Blaut criticized Guns, Germs, and Steel, among other reasons, for reviving the theory of environmental determinism, and described Diamond as an example of a modern Eurocentric historian. Blaut criticizes Diamond's loose use of the terms "Eurasia" and "innovative", which he believes misleads the reader into presuming that Western Europe is responsible for technological inventions that arose in the Middle East and Asia.

Harvard International Relations (IR) scholar Stephen Walt called the book "an exhilarating read" and put it on a list of the ten books every IR student should read.

Berkeley economist Brad DeLong describes the book as a "work of complete and total genius".

John Brätland, an Austrian school economist of the U.S. Department of the Interior, complained in a Journal of Libertarian Studies article that Guns, Germs, and Steel entirely neglects individual action, concentrating solely on the centralized state; fails to understand how societies form (assessing that societies do not exist or form without a strong government); and ignores various economical institutions, such as monetary exchange that would allow societies to "rationally reckon scarcities and the value of actions required to replace what is depleted through human use". Instead, the author concludes that because there was no sophisticated division of labor, private property rights, and monetary exchange, societies like that on Easter Island could never progress from the nomadic stage to a complex society. Those factors, according to Brätland, are crucial, and at the same time neglected by Diamond.

Anthropologist Jason Antrosio describes Guns, Germs, and Steel as a form of "academic porn". Diamond's account makes all the factors of European domination a product of a distant and accidental history and has almost no role for human agency–the ability people have to make decisions and influence outcomes. Europeans become inadvertent, accidental conquerors. Natives succumb passively to their fate. "Jared Diamond has done a huge disservice to the telling of human history. He has tremendously distorted the role of domestication and agriculture in that history. Unfortunately his story-telling abilities are so compelling that he has seduced a generation of college-educated readers."

Other critiques have been made over the author's position on the agricultural revolution. The transition from hunting and gathering to agriculture is not necessarily a one way process. It has been argued that hunting and gathering represents an adaptive strategy, which may still be exploited, if necessary, when environmental change causes extreme food stress for agriculturalists. In fact, it is sometimes difficult to draw a clear line between agricultural and hunter-gatherer societies, especially since the widespread adoption of agriculture and resulting cultural diffusion that has occurred in the last 10,000 years.

Publication

Guns, Germs, and Steel was first published by W. W. Norton in March 1997. It was subsequently published in Great Britain under the title Guns, Germs, and Steel: A Short History of Everybody for the Last 13,000 Years by Vintage in 1998 (ISBN 978-0099302780). It was a selection of Book of the Month Club, History Book Club, Quality Paperback Book Club, and Newbridge Book Club.
In 2003 and 2007, the author published new English-language editions that included information collected since the previous editions. The new information did not change any of the original edition's conclusions.

Neolithic Revolution

From Wikipedia, the free encyclopedia

The Neolithic Revolution, Neolithic Demographic Transition, Agricultural Revolution, or First Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly larger population possible. 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.

Archaeological data indicates that the domestication of various types of plants and animals happened in separate locations worldwide, starting in the geological epoch of the Holocene around 12,500 years ago. It was the world's first historically verifiable revolution in agriculture. The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a downturn in human nutrition.

The Neolithic Revolution involved far more than the adoption of a limited set of food-producing techniques. During the next millennia it would transform the small and mobile groups of hunter-gatherers that had hitherto dominated human pre-history into sedentary (non-nomadic) societies based in built-up villages and towns. These societies radically modified their natural environment by means of specialized food-crop cultivation, with activities such as irrigation and deforestation which allowed the production of surplus food. Other developments found very widely are the domestication of animals, pottery, polished stone tools, and rectangular houses.

These developments, sometimes called the Neolithic package, provided the basis for densely populated settlements, specialization and division of labour, more trade, the development of non-portable art and architecture, centralized administrations and political structures, hierarchical ideologies, depersonalized systems of knowledge (e.g. writing), and property ownership. The earliest known civilization developed in Sumer in southern Mesopotamia (c. 5,500 BP); its emergence also heralded the beginning of the Bronze Age.

The relationship of the above-mentioned Neolithic characteristics to the onset of agriculture, their sequence of emergence, and empirical relation to each other at various Neolithic sites remains the subject of academic debate, and varies from place to place, rather than being the outcome of universal laws of social evolution. The Levant saw the earliest developments of the Neolithic Revolution from around 10,000 BCE, followed by sites in the wider Fertile Crescent.

The term Neolithic Revolution was coined in 1923 by V. Gordon Childe to describe the first in a series of agricultural revolutions in Middle Eastern history. The period is described as a "revolution" to denote its importance, and the great significance and degree of change affecting the communities in which new agricultural practices were gradually adopted and refined.

The beginning of this process in different regions has been dated from 10,000 to 8,000 BC in the Fertile Crescent and perhaps 8000 BC in the Kuk Early Agricultural Site of Melanesia. This transition everywhere seems associated with a change from a largely nomadic hunter-gatherer way of life to a more settled, agrarian-based one, with the inception of the domestication of various plant and animal species—depending on the species locally available, and probably also influenced by local culture. Recent archaeological research suggests that in some regions such as the Southeast Asian peninsula, the transition from hunter-gatherer to agriculturalist was not linear, but region-specific.
There are several competing (but not mutually exclusive) 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 Childe's book Man Makes Himself. This theory maintains that as the climate got drier due to the Atlantic depressions shifting northward, communities contracted to oases where they were forced into close association with animals, which were then domesticated together with planting of seeds. However, today this theory has little support amongst archaeologists because subsequent climate data suggests that the region was getting wetter rather than drier.
  • The Hilly Flanks hypothesis, proposed by Robert Braidwood in 1948, suggests that agriculture began in the hilly flanks of the Taurus and Zagros mountains, where the climate was not drier as Childe had believed, and fertile land supported a variety of plants and animals amenable to domestication.
  • 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.
  • The Demographic theories proposed by Carl Sauer and adapted by Lewis Binford and Kent Flannery posit an increasingly sedentary population that expanded up to the carrying capacity of the local environment and required more food than could be gathered. 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 evolutionary adaptation of plants and humans. Starting with domestication by protection of wild plants, it led to specialization of location and then full-fledged domestication.
  • Peter Richerson, Robert Boyd, and Robert Bettinger make a case for the development of agriculture coinciding with an increasingly stable climate at the beginning of the Holocene. Ronald Wright's book and Massey Lecture Series A Short History of Progress popularized this hypothesis.
  • The postulated Younger Dryas impact event, claimed to be in part responsible for megafauna extinction and ending the last glacial period, could have provided circumstances that required the evolution of agricultural societies for humanity to survive. The agrarian revolution itself is a reflection of typical overpopulation by certain species following initial events during extinction eras; this overpopulation itself ultimately propagates the extinction event.
  • Leonid Grinin argues that whatever plants were cultivated, the independent invention of agriculture always took place in special natural environments (e.g., South-East Asia). It is supposed that the cultivation of cereals started somewhere in the Near East: in the hills of Palestine or Egypt. So Grinin dates the beginning of the agricultural revolution within the interval 12,000 to 9,000 BP, though in some cases the first cultivated plants or domesticated animals' bones are even of a more ancient age of 14–15 thousand years ago.
  • Andrew Moore suggested that the Neolithic Revolution originated over long periods of development in the Levant, possibly beginning during the Epipaleolithic. In "A Reassessment of the Neolithic Revolution", Frank Hole further expanded the relationship between plant and animal domestication. He suggested the events could have occurred independently over different periods of time, in as yet unexplored locations. He noted that no transition site had been found documenting the shift from what he termed immediate and delayed return social systems. He noted that the full range of domesticated animals (goats, sheep, cattle and pigs) were not found until the sixth millennium at Tell Ramad. Hole concluded that "close attention should be paid in future investigations to the western margins of the Euphrates basin, perhaps as far south as the Arabian Peninsula, especially where wadis carrying Pleistocene rainfall runoff flowed."

Domestication of plants

Spread to Europe

Once agriculture started gaining momentum, around 9000 BC, human activity resulted in the selective breeding of cereal grasses (beginning with emmer, einkorn and barley), and not simply of those that would favour greater caloric returns through larger seeds. Plants with traits such as small seeds or bitter taste would have been seen as undesirable. Plants that rapidly shed their seeds on maturity tended not to be gathered at harvest, therefore not stored and not seeded the following season; years of harvesting selected for strains that retained their edible seeds longer.

Several plant species, the "pioneer crops" or Neolithic founder crops, were identified by Daniel Zohary, who highlighted the importance of the three cereals, and suggested that domestication of flax, peas, chickpeas, bitter vetch and lentils came a little later. Based on analysis of the genes of domesticated plants, he preferred theories of a single, or at most a very small number of domestication events for each taxon that spread in an arc from the Levantine corridor around the Fertile Crescent and later into Europe. Gordon Hillman and Stuart Davies carried out experiments with wild wheat varieties to show that the process of domestication would have occurred over a relatively short period of between 20 and 200 years. Some of these pioneering attempts failed at first and crops were abandoned, sometimes to be taken up again and successfully domesticated thousands of years later: rye, tried and abandoned in Neolithic Anatolia, made its way to Europe as weed seeds and was successfully domesticated in Europe, thousands of years after the earliest agriculture. Wild lentils presented a different problem: most of the wild seeds do not germinate in the first year; the first evidence of lentil domestication, breaking dormancy in their first year, was found in the early Neolithic at Jerf el Ahmar (in modern Syria), and quickly spread south to the Netiv HaGdud site in the Jordan Valley. This process of domestication allowed the founder crops to adapt and eventually become larger, more easily harvested, more dependable in storage and more useful to the human population.

Found in large quantities at Qaraoun II and often with Heavy Neolithic tools in the flint workshops of the Beqaa Valley in Lebanon. Suggested by James Mellaart to be older than the Pottery Neolithic of Byblos (around 8,400 cal. BP).

Selectively propagated figs, wild barley and wild oats were cultivated at the early Neolithic site of Gilgal I, where in 2006 archaeologists found caches of seeds of each in quantities too large to be accounted for even by intensive gathering, at strata datable to c. 11,000 years ago. Some of the plants tried and then abandoned during the Neolithic period in the Ancient Near East, at sites like Gilgal, were later successfully domesticated in other parts of the world.

Once early farmers perfected their agricultural techniques like irrigation, their crops would yield surpluses that needed storage. Most hunter gatherers could not easily store food for long due to their migratory lifestyle, whereas those with a sedentary dwelling could store their surplus grain. Eventually granaries were developed that allowed villages to store their seeds longer. So with more food, the population expanded and communities developed specialized workers and more advanced tools.

The process was not as linear as was once thought, but a more complicated effort, which was undertaken by different human populations in different regions in many different ways.

In the Fertile Crescent

Early agriculture is believed to have originated and become widespread in Southwest Asia around 10,000–9,000 BP, though earlier individual sites have been identified. The Fertile Crescent region of Southwest Asia is the centre of domestication for three cereals (einkorn wheat, emmer wheat and barley), four legumes (lentil, pea, bitter vetch and chickpea), and flax. Domestication was a slow process involving multiple sites for each crop.

Finds of large quantities of seeds and a grinding stone at the paleolithic site of Ohalo II in the vicinity of the Sea of Galilee, dated to around 19,400 BP, has shown some of the earliest evidence for advanced planning of plant food consumption and suggests that humans at Ohalo II processed the grain before consumption. Tell Aswad is the oldest site of agriculture, with domesticated emmer wheat dated to 10,800 BP. Soon after came hulled, two-row barley found domesticated earliest at Jericho in the Jordan valley and Iraq ed-Dubb in Jordan. Other sites in the Levantine corridor that show the first evidence of agriculture include Wadi Faynan 16 and Netiv Hagdud. Jacques Cauvin noted that the settlers of Aswad did not domesticate on site, but "arrived, perhaps from the neighbouring Anti-Lebanon, already equipped with the seed for planting". The Heavy Neolithic Qaraoun culture has been identified at around fifty sites in Lebanon around the source springs of the River Jordan, but never reliably dated.

In China

Northern China appears to have been the domestication center for foxtail millet (Setaria italica) and broomcorn millet (Panicum miliaceum) with evidence of domestication of these species approximately 8,000 years ago. These species were subsequently widely cultivated in the Yellow River basin (7,500 years ago). Rice was domesticated in southern China later on. Soybean was domesticated in northern China 4,500 years ago. Orange and peach also originated in China. They were cultivated around 2500 BC.

In Africa

Nile River Valley, Egypt

On the African continent, three areas have been identified as independently developing agriculture: the Ethiopian highlands, the Sahel and West Africa. By contrast, Agriculture in the Nile River Valley is thought to have developed from the original Neolithic Revolution in the Fertile Crescent. Many grinding stones are found with the early Egyptian Sebilian and Mechian cultures and evidence has been found of a neolithic domesticated crop-based economy dating around 7,000 BP. Unlike the Middle East, this evidence appears as a "false dawn" to agriculture, as the sites were later abandoned, and permanent farming then was delayed until 6,500 BP with the Tasian and Badarian cultures and the arrival of crops and animals from the Near East.

Bananas and plantains, which were first domesticated in Southeast Asia, most likely Papua New Guinea, were re-domesticated in Africa possibly as early as 5,000 years ago. Asian yams and taro were also cultivated in Africa.

The most famous crop domesticated in the Ethiopian highlands is coffee. In addition, khat, ensete, noog, teff and finger millet were also domesticated in the Ethiopian highlands. Crops domesticated in the Sahel region include sorghum and pearl millet. The kola nut was first domesticated in West Africa. Other crops domesticated in West Africa include African rice, yams and the oil palm.

Agriculture spread to Central and Southern Africa in the Bantu expansion during the 1st millennium BC to 1st millennium AD.

In the Americas

Maize (corn), beans and squash were among the earliest crops domesticated in Mesoamerica, with maize beginning about 4000 BC, squash as early as 6000 BC, and beans by no later than 4000 BC. Potatoes and manioc were domesticated in South America. In what is now the eastern United States, Native Americans domesticated sunflower, sumpweed and goosefoot around 2500 BC. Sedentary village life based on farming did not develop until the second millennium BC, referred to as the formative period.

In New Guinea

Evidence of drainage ditches at Kuk Swamp on the borders of the Western and Southern Highlands of Papua New Guinea shows evidence of the cultivation of taro and a variety of other crops, dating back to 11,000 BP. Two potentially significant economic species, taro (Colocasia esculenta) and yam (Dioscorea sp.), have been identified dating at least to 10,200 calibrated years before present (cal BP). Further evidence of bananas and sugarcane dates to 6,950 to 6,440 BP. This was at the altitudinal limits of these crops, and it has been suggested that cultivation in more favourable ranges in the lowlands may have been even earlier. CSIRO has found evidence that taro was introduced into the Solomon Islands for human use, from 28,000 years ago, making taro cultivation the earliest crop in the world. It seems to have resulted in the spread of the Trans–New Guinea languages from New Guinea east into the Solomon Islands and west into Timor and adjacent areas of Indonesia. This seems to confirm the theories of Carl Sauer who, in "Agricultural Origins and Dispersals", suggested as early as 1952 that this region was a centre of early agriculture.

Domestication of animals

When hunter-gathering began to be replaced by sedentary food production it became more profitable to keep animals close at hand. Therefore, it became necessary to bring animals permanently to their settlements, although in many cases there was a distinction between relatively sedentary farmers and nomadic herders. The animals' size, temperament, diet, mating patterns, and life span were factors in the desire and success in domesticating animals. Animals that provided milk, such as cows and goats, offered a source of protein that was renewable and therefore quite valuable. The animal’s ability as a worker (for example ploughing or towing), as well as a food source, also had to be taken into account. Besides being a direct source of food, certain animals could provide leather, wool, hides, and fertilizer. Some of the earliest domesticated animals included dogs (East Asia, about 15,000 years ago), sheep, goats, cows, and pigs.

Domestication of animals in the Middle East

The Middle East served as the source for many animals that could be domesticated, such as sheep, goats and pigs. This area was also the first region to domesticate the dromedary. Henri Fleisch discovered and termed the Shepherd Neolithic flint industry from the Bekaa Valley in Lebanon and suggested that it could have been used by the earliest nomadic shepherds. He dated this industry to the Epipaleolithic or Pre-Pottery Neolithic as it is evidently not Paleolithic, Mesolithic or even Pottery Neolithic. The presence of these animals gave the region a large advantage in cultural and economic development. As the climate in the Middle East changed and became drier, many of the farmers were forced to leave, taking their domesticated animals with them. It was this massive emigration from the Middle East that would later help distribute these animals to the rest of Afroeurasia. This emigration was mainly on an east-west axis of similar climates, as crops usually have a narrow optimal climatic range outside of which they cannot grow for reasons of light or rain changes. For instance, wheat does not normally grow in tropical climates, just like tropical crops such as bananas do not grow in colder climates. Some authors, like Jared Diamond, have postulated that this East-West axis is the main reason why plant and animal domestication spread so quickly from the Fertile Crescent to the rest of Eurasia and North Africa, while it did not reach through the North-South axis of Africa to reach the Mediterranean climates of South Africa, where temperate crops were successfully imported by ships in the last 500 years. Similarly, the African Zebu of central Africa and the domesticated bovines of the fertile-crescent — separated by the dry sahara desert — were not introduced into each other's region.

Consequences

Social change

World population (estimated) did not rise for a few millennia after the Neolithic revolution.

Despite the significant technological advance, the Neolithic revolution did not lead immediately to a rapid growth of population. Its benefits appear to have been offset by various adverse effects, mostly diseases and warfare.

The introduction of agriculture has not necessarily led to unequivocal progress. The nutritional standards of the growing Neolithic populations were inferior to that of hunter-gatherers. Several ethnological and archaeological studies conclude that the transition to cereal-based diets caused a reduction in life expectancy and stature, an increment in infant mortality and infectious diseases, the development of chronic, inflammatory or degenerative diseases (such as obesity, type 2 diabetes and cardiovascular diseases) and multiple nutritional deficiencies, including vitamin deficiencies, iron deficiency anemia and mineral disorders affecting bones (such as osteoporosis and rickets) and teeth. Average height went down from 5'10" (178 cm) for men and 5'6" (168 cm) for women to 5'5" (165 cm) and 5'1" (155 cm), respectively, and it took until the twentieth century for average human height to come back to the pre-Neolithic Revolution levels.

The traditional view is that agricultural food production supported a denser population, which in turn supported larger sedentary communities, the accumulation of goods and tools, and specialization in diverse forms of new labor. The development of larger societies led to the development of different means of decision making and to governmental organization. Food surpluses made possible the development of a social elite who were not otherwise engaged in agriculture, industry or commerce, but dominated their communities by other means and monopolized decision-making. Jared Diamond (in The World Until Yesterday) identifies the availability of milk and cereal grains as permitting mothers to raise both an older (e.g. 3 or 4 year old) and a younger child concurrently. The result is that a population can increase more rapidly. Diamond points out that agriculture brought about deep social divisions and encouraged gender inequality.

Subsequent revolutions

Andrew Sherratt has argued that following upon the Neolithic Revolution was a second phase of discovery that he refers to as the secondary products revolution. Animals, it appears, were first domesticated purely as a source of meat. The Secondary Products Revolution occurred when it was recognised that animals also provided a number of other useful products. These included:
Sherratt argued that this phase in agricultural development enabled humans to make use of the energy possibilities of their animals in new ways, and permitted permanent intensive subsistence farming and crop production, and the opening up of heavier soils for farming. It also made possible nomadic pastoralism in semi arid areas, along the margins of deserts, and eventually led to the domestication of both the dromedary and Bactrian camel. Overgrazing of these areas, particularly by herds of goats, greatly extended the areal extent of deserts.

Living in one spot would have more easily permitted the accrual of personal possessions and an attachment to certain areas of land. From such a position, it is argued, prehistoric people were able to stockpile food to survive lean times and trade unwanted surpluses with others. Once trade and a secure food supply were established, populations could grow, and society would have diversified into food producers and artisans, who could afford to develop their trade by virtue of the free time they enjoyed because of a surplus of food. The artisans, in turn, were able to develop technology such as metal weapons. Such relative complexity would have required some form of social organisation to work efficiently, so it is likely that populations that had such organisation, perhaps such as that provided by religion, were better prepared and more successful. In addition, the denser populations could form and support legions of professional soldiers. Also, during this time property ownership became increasingly important to all people. Ultimately, Childe argued that this growing social complexity, all rooted in the original decision to settle, led to a second Urban Revolution in which the first cities were built.

Disease

Throughout the development of sedentary societies, disease spread more rapidly than it had during the time in which hunter-gatherer societies existed. Inadequate sanitary practices and the domestication of animals may explain the rise in deaths and sickness following the Neolithic Revolution, as diseases jumped from the animal to the human population. Some examples of infectious diseases spread from animals to humans are influenza, smallpox, and measles. In concordance with a process of natural selection, the humans who first domesticated the big mammals quickly built up immunities to the diseases as within each generation the individuals with better immunities had better chances of survival. In their approximately 10,000 years of shared proximity with animals, such as cows, Eurasians and Africans became more resistant to those diseases compared with the indigenous populations encountered outside Eurasia and Africa. For instance, the population of most Caribbean and several Pacific Islands have been completely wiped out by diseases. 90% or more of many populations of the Americas were wiped out by European and African diseases before recorded contact with European explorers or colonists. Some cultures like the Inca Empire did have a large domestic mammal, the llama, but llama milk was not drunk, nor did llamas live in a closed space with humans, so the risk of contagion was limited. According to bioarchaeological research, the effects of agriculture on physical and dental health in Southeast Asian rice farming societies from 4000 to 1500 B.P. was not detrimental to the same extent as in other world regions.

Technology

In his book Guns, Germs, and Steel, Jared Diamond argues that Europeans and East Asians benefited from an advantageous geographical location that afforded them a head start in the Neolithic Revolution. Both shared the temperate climate ideal for the first agricultural settings, both were near a number of easily domesticable plant and animal species, and both were safer from attacks of other people than civilizations in the middle part of the Eurasian continent. Being among the first to adopt agriculture and sedentary lifestyles, and neighboring other early agricultural societies with whom they could compete and trade, both Europeans and East Asians were also among the first to benefit from technologies such as firearms and steel swords.

Archaeogenetics

The dispersal of Neolithic culture from the Middle East has recently been associated with the distribution of human genetic markers. In Europe, the spread of the Neolithic culture has been associated with distribution of the E1b1b lineages and Haplogroup J that are thought to have arrived in Europe from North Africa and the Near East respectively. In Africa, the spread of farming, and notably the Bantu expansion, is associated with the dispersal of Y-chromosome haplogroup E1b1a from West Africa.

Kennewick Man is the name generally given to the skeletal remains of a prehistoric Paleoamerican man found on a bank of the Columbia River in Kennewick, Washington, United States, on July 28, 1996. It is one of the most complete ancient skeletons ever found. Radiocarbon tests on bone have shown it to date from 8.9k to 9k calibrated years before present. In the early 2000s, genetic analysis did not have sufficient techniques to analyze such ancient DNA. By 2013, however, techniques had improved and the ancient DNA (aDNA) was analyzed. In June 2015 the team announced their conclusions, that Kennewick Man had most in common with Native Americans among living peoples, including those in the Columbia River region where he was found.

The discovery of the remains led to considerable controversy for more than a decade. The Umatilla people and other tribes have wanted the remains returned to them for reburial under the federal Native American Graves Protection and Repatriation Act (NAGPRA). The law was designed to remedy long-standing wrongs done to tribes and to facilitate the return of human remains and cultural objects unlawfully obtained or taken from them. In this case, the archaeologists who discovered the bones, James Chatters and Douglas Owsley, the latter with the Smithsonian Institution, both asserted that the bones were only distantly related to today's Native Americans. They also said the remains had features that more closely resembled Polynesian or Southeast Asian peoples, a finding that would exempt the bones from NAGPRA.

Kennewick Man became the subject of a controversial nine-year court case between the United States Army Corps of Engineers (USACE), scientists, and Native American tribes who claimed ownership of the remains. Under NAGPRA, the tribes would maintain the right to rebury the remains of Kennewick Man and to refuse to allow scientific study of the man they referred to as "The Ancient One". The US Army Corps of Engineers, which oversaw the land where the remains were found, initially agreed to comply with the requests of the tribes. Before the transfer could be made, Owsley, along with seven other anthropologists, including Smithsonian colleague Dennis Stanford, filed a lawsuit asserting the scientific right to study the skeleton.

In February 2004, the United States Court of Appeals for the Ninth Circuit ruled that a direct cultural link between any of the Native American tribes and Kennewick Man could not be proved because of the age of the remains. Its ruling allowed scientific study of the remains to continue while the USACE retained custody of the remains. In July 2005, a team of scientists from around the United States convened in Seattle to study the remains in detail. Their research results were published in 2014 in Kennewick Man: The Scientific Investigation of an Ancient American Skeleton edited by Douglas Owsley and Richard Jantz. In June 2015, it was made public that scientists at the University of Copenhagen in Denmark determined through DNA from 8,500‑year-old bones that Kennewick Man is, in fact, related to modern Native Americans, including the Confederated Tribes of the Colville Reservation from the region in which his bones were found. The international team of scientists had communicated that finding to the Army Corps of Engineers in 2013.

Chatters, the discoverer of the bones, had long changed his conclusions after finding similar skull shapes among confirmed ancestors of Native Americans. The results did not surprise scientists who study the genetics of ancient people, as almost all Paleoamericans "have shown strong genetic ties with modern Native Americans". Analysis showed that Kennewick Man is "very closely related to the Colville" tribe in northeast Washington. The results were published in Nature magazine. In September 2016, the US House and Senate passed legislation to return the ancient bones to a coalition of Columbia Basin tribes for reburial according to their traditions. The coalition includes the Confederated Tribes of the Colville Reservation, the Confederated Tribes and Bands of the Yakama Nation, the Nez Perce Tribe, the Confederated Tribes of the Umatilla Reservation, and the Wanapum Band of Priest Rapids. The remains were buried on February 18, 2017, with 200 members of five Columbia Basin tribes in attendance, at an undisclosed location in the area.

Discovery

The discovery of Kennewick Man was accidental. Will Thomas and David Deacy were attending the annual hydroplane races on July 28 1996 and found the skull in a reservoir on the Columbia River at Columbia Park in Kennewick, Washington. The remains had become exposed due to erosion and been scattered by water forces in the reservoir.

Following delivery of the cranium by the coroner, the remains were examined by archaeologist James Chatters. In ten visits to the site, Chatters managed to collect 350 bones and pieces of bone, which, with the skull, completed almost an entire skeleton. The cranium was fully intact with all the teeth that had been present at the time of death. All major bones were found, except the sternum and a few bones of the hands and feet. Many of the bones were broken into several pieces. After studying the bones, Chatters concluded that they belonged to "a male of late middle age (40-55 years), and tall (170 to 176 cm, 5′7″ to 5′9″), and was fairly muscular with a slender build". Chatters said that the "presence of Caucasoid traits [and a] lack of definitive Native-American characteristics", as well as the apparent context of the skeleton as part of an early Paleo-American group led him to conclude that the body was Caucasian. The anthropological term "Caucasian" was confused by some members of the media and public, who interpreted it as meaning "white" or "European", however.

A small bone fragment was submitted to the University of California, Riverside, for radiocarbon dating, which indicated the age of the skeleton was approximately 9,300 to 9,600 years old (8,400 uncalibrated "radiocarbon years"), and not from the 19th century, as had originally been thought. Subsequent radiocarbon dating indicates a somewhat younger age of 8.9k to 9k cal years BP.

Chatters found that bone had partially grown around a 79 mm (3.1 in) stone projectile lodged in the ilium, part of the pelvic bone. On X-ray, nothing appeared. Chatters put the bone through a CT scan, and it was discovered that the projectile was made from a siliceous gray stone that was found to have igneous (intrusive or volcanic) origins. The projectile, leaf-shaped, long, and broad, with serrated edges, fit the definition of a Cascade point. This type of point is a feature of the Cascade phase in indigenous ancient history, which occurred roughly 7,500 to 12,000 years BP.

To investigate the mystery of Kennewick Man further and determine whether the skeleton belonged to the Umatilla Native American tribe, who occupied the territory where it was found, scientists analyzed an extraction of DNA. However, according to their report, "available technology and protocols do not allow the analysis of ancient DNA from these remains."

Forensic anthropologist Douglas Owsley, who later led the scientific team that examined Kennewick Man's skeleton in 2005, discovered that the bones in Kennewick Man's arms were bent. Owsley theorized that this was the result of powerful muscles built up over the course of a lifetime of hunting and spearfishing. Kennewick Man was found to be right-handed, as the bones of the right arm are noticeably larger than the bones found in his left arm.

Chatters et al. conducted a graphic comparison, including size, of Kennewick Man to eighteen modern populations. They found Kennewick Man to be most closely related to the Ainu, an ancient indigenous people of Japan. However, when size was excluded as a factor, no association to any population was established. Chatters said that anthropologist C. Loring Brace classified Ainu and Polynesians as a single craniofacial Jomon-Pacific cluster, and Chatters said "Polynesians have craniofacial similarities to Asian, Australian and European peoples". Brace said in a 2006 interview with the Tri-City Herald that his analysis of the skeleton suggested that Kennewick Man was related to the Ainu.

Anthropologist Joseph Powell of the University of New Mexico was also allowed to examine the remains. Powell used craniometric data obtained by anthropologist William White Howells of Harvard University and anthropologist Tsunehiko Hanihara of Saga University; this had the advantage of including data drawn from Asian and North American populations. Powell said that Kennewick Man was not European but most resembled the Ainu and Polynesians. Powell said that the Ainu descend from the Jōmon people, an East Asian population with "closest biological affinity with south-east Asians rather than western Eurasian peoples". Powell said that dental analysis showed the skull to have a 94-percent consistency with being of a Sundadont group like the Ainu and Polynesians and only a 48-percent consistency with being of a Sinodont group like that of North Asia. Powell said analysis of the skull showed it to be "unlike American Indians and Europeans". Powell concluded that the remains were "clearly not a Caucasoid unless Ainu and Polynesians are considered Caucasoid".

The biological diversity among ancient skulls in the Americas has complicated attempts to establish how closely Kennewick Man is related to any modern Native American tribes. Skulls older than 8000 years old have been found to possess greater physical diversity than do those of modern Native Americans. The origin of that diversity, whether from different lineages or local adaptation, is a matter of debate.

In 2005, a 10-day examination of the skeleton, led by forensic anthropologist Douglas Owsley, revealed that Kennewick Man had arthritis in his right elbow, both of his knees, and several vertebrae but not severe enough to be crippling. Owsley discovered that Kennewick Man had also suffered some trauma in his lifetime, which was evident by a fractured rib that had healed, a depression fracture on his forehead, and a similar indentation on the left side of the head, and a spear jab that healed. Despite earlier theories regarding his age, the Owsley team thinks he may have been as young as 38 at the time of death.

Kennewick Man was found to have been deliberately buried. By examining the calcium carbonate left behind as underground water collected on the underside of the bones and then evaporated, scientists were able to conclude that Kennewick Man was lying on his back with his feet rolled slightly outward and his arms at his side, with the palms facing down, a position that could not have been accidental.

The findings of the study team convened under Owsley have been published in Kennewick Man, The Scientific Investigation of an Ancient American Skeleton (2014) (Douglas W. Owsley and Richard L. Jantz, editors). Researchers from multiple disciplines, including forensic anthropology, physical anthropology, and isotope chemistry, reconstruct the life history and heritage of that individual.
Measurements of carbon, nitrogen, and oxygen isotope ratios in the bone collagen indicate that the man lived almost exclusively on a diet of marine mammals for the last 20 or so years of his life and that the water he drank was glacial melt water. The closest marine coastal environment where glacial melt water could have been found at the time of Kennewick Man was Alaska. That, combined with the location of the find, led to the conclusion that the individual led a highly mobile, water-borne lifestyle centered on the northern coast.

Craniofacial measurements of the skull were found to resemble those of the Ainu, the descendants of the Jōmon aboriginals of Japan. The Jōmon people and Kennewick Man are thought by the authors to share common ancestors among seafaring peoples of coastal Asia with similar craniofacial characteristics.

Advances in genetic research since the first work was done on Kennewick Man has made it possible to analyze ancient DNA (known as aDNA). In June 2015, new results of such aDNA analysis were announced, suggesting that the remains are more closely related to modern Native Americans than to any other living population. His genetic profile was particularly close to that of members of the Confederated Tribes of the Colville Reservation. Of the five tribes that originally claimed Kennewick Man as an ancestor, their members were the only ones to donate DNA samples for evaluation. The lack of genomes from North American aboriginal populations have made it impossible to ascertain Kennewick Man's nearest living relatives among regional Native American tribes. His Y-DNA haplogroup is Q-M3 and his mitochondrial DNA is X2a, both uniparental genetic markers found almost exclusively in Native Americans.

Scientific significance

The discovery of Kennewick Man, along with other ancient skeletons, has furthered scientific debate over the exact origin and history of early Native American people. One hypothesis holds that a single source of migration occurred, consisting of hunters and gatherers following large herds of game who wandered across the Bering land bridge. An alternative hypothesis is that more than one source population was involved in migration immediately following the Last Glacial Maximum (LGM), which occurred ~22k to ~18k years BP, and that the land migration through Beringia was either preceded by or roughly synchronous with a waterborne migration from coastal Asia.

The similarity of some ancient skeletal remains in the Americas, such as Kennewick Man, to coastal Asian phenotypes is suggestive of more than one migration source. Classification of DNA from ancient skeletons such as Kennewick Man and others of similar phenotype may or may not reveal genetic affiliation between them, with either Beringian or coastal Asian source populations.

Regardless of the debate over whether there were more than one source of migration following the LGM, Kennewick Man has yielded insight into the marine lifestyle and mobility of early coastal migrants.

Scientific criticism of Owsley study

In 2012, Burke Museum archeologists voiced concern and criticism of the Owsley team's findings. First, it was noted that no one outside of Owsley's team had an opportunity to examine the Smithsonian's data to see how the team reached its conclusions.

Second, the absence of peer-reviewed articles published prior to Owsley unveiling the bones' secrets was criticized. Standard procedure in the academic world is for scientists to submit articles to scholarly journals, have other experts review the articles prior to publication, and have experts debate results after publication. While Owsley consulted extensively with his group of experts, he has yet to publish a scholarly article on Kennewick Man. "He's never published any scientific results of his studies. There's no place for anyone to look at the actual data. You have to have a higher amount of scrutiny in the scientific process," said Peter Lape, the curator of archaeology at the Burke Museum and an associate professor of archaeology at the University of Washington.

Third, Owsley's non-Native argument hinged on the assumption that Kennewick Man's skull was a reliable means of assessing ancestry. This was a "nineteenth-century skull science paradigm", said David Hurst Thomas, a curator at the American Museum of Natural History. Skulls are no longer used as the basis for classifying remains, as DNA evidence is more accurate and reliable.

Finally, the process raised conflict of interest questions. The team fighting for custody of the remains to perform a study would draw conclusions that would influence the outcome of that battle.

Ownership controversy

According to NAGPRA, if human remains are found on federal lands and their cultural affiliation to a Native American tribe can be established, the affiliated tribe may claim them. The Umatilla tribe requested custody of the remains and wanted to bury them according to tribal tradition. Their claim was contested by researchers hoping to study the remains.

The Umatilla argued that their oral history goes back 10,000 years and say that their people have been present on their historical territory since the dawn of time.

Robson Bonnichsen and seven other anthropologists sued the United States for the right to conduct tests on the skeleton. On February 4, 2004, the United States Court of Appeals for the Ninth Circuit panel rejected the appeal brought by the United States Army Corps of Engineers and the Umatilla, Colville, Yakama, Nez Perce, and other tribes on the grounds that they were unable to show any evidence of kinship. The presiding judge found that the US government had acted in bad faith and awarded attorney’s fees of $2,379,000 to the plaintiffs.

On April 7, 2005, during the 109th Congress, United States senator John McCain introduced an amendment to NAGPRA, which (section 108) would have changed the definition of "Native American" from being that which "is indigenous to the United States" to "is or was indigenous to the United States". However, the 109th Congress concluded without enacting the bill. By the bill's definition, Kennewick Man would have been classified as Native American regardless of whether any link to a contemporary tribe could be found.

Proponents argue that it agrees with current scientific understanding, which is that it is not in all cases possible for prehistoric remains to be traced to current tribal entities, partly because of social upheaval, forced resettlement, and extinction of entire ethnicities caused by disease and warfare. Passage of this bill would not resolve the controversy related to Kennewick Man, as there would have to be a determination of which Native American group should take possession of the remains if he could not be definitively linked with a current tribe. To be of practical use in a historical and prehistorical context, some argue further that the phrase "Native American" should be applied so that it spans the entire range from the Clovis culture (which cannot be positively assigned to any contemporary tribal group) to the Métis, a group of mixed ancestry who developed as an ethnic group as a consequence of European contact, yet constitute a distinct cultural entity.

As of 2014, the remains were at the Burke Museum at the University of Washington, where they were deposited in October 1998. The Burke Museum was the court-appointed neutral repository for the remains and did not exhibit them. They were then still legally the property of the US Army Corps of Engineers, as they were found on land under its custody. The tribes still wanted the remains to be reburied. The Corps of Engineers continued to deny scientists' requests to conduct additional studies of the skeleton. In light of the findings that Kennewick Man is related to present-day Native Americans of the Pacific Northwest, public officials such as Governor Jay Inslee and Senator Patty Murray called on the Corps of Engineers, who retained possession of Kennewick Man, to return the remains to Native American tribes.

DNA

A first attempt at DNA analysis in the early 2000s found that meaningful results were impossible to attain from the ancient DNA (aDNA) with the techniques available at that time. With changes in technology, additional DNA testing of remains has been conducted by an analytical laboratory in Denmark. A 2013 e-mail from the laboratory to the US Corps of Engineers stated their belief, based on preliminary results of analysis, that the specimen contained Native American DNA. The laboratory was not ready to release final results or discuss the conclusions. In June 2015 the study team announced they had concluded their DNA analysis, finding that "Kennewick Man is closer to modern Native Americans than to any other population worldwide." They said that genetic comparisons show "continuity with Native North Americans" The same study confirmed the mitochondrial haplogroup X2a and the Y-chromosome haplogroup Q-M3 of Kennewick Man, both lineages are found almost exclusively among modern Native Americans.

Race factor

Reporter Jack Hitt wrote in 2005 that "racial preferences color" the controversy about the genetic origin and ancestry of Kennewick Man. James Chatters, the first anthropologist to examine the skull of Kennewick man, said that it lacked the "definitive characteristics of the classic Mongoloid stock to which modern Native Americans belong", adding that many of the characteristics of the skull "are definitive of modern-day Caucasoid peoples". In 1998, Chatters reconstructed the facial features of the skull. Observers said that Kennewick Man resembled British actor Patrick Stewart.

The use of the word "Caucasoid" in Chatter's report and his facial reconstruction were taken by many to mean that Kennewick Man was "Caucasian", European, and "white" rather than an ancestor of present-day Native Americans., although the term "Caucasoid" had also been applied to the Ainu of northern Japan, and an Ainu genetic connection would have been more plausible here. In 1998, The New York Times reported "White supremacist groups are among those who used Kennewick Man to claim that Caucasians came to America well before Native Americans." Additionally, Asatru Folk Assembly, a neopagan organization, sued to have the bones genetically tested before it was adjudicated that Kennewick Man was an ancestor of present-day Native Americans. Native American tribes asserted that the claims that Kennewick Man was of European origin were an attempt to evade the law governing ownership and burial of ancient bones. The Corps of Engineers and federal government supported the Native American claim in what became a long-running lawsuit.

The results of genetic investigations published in 2015 strongly pointed toward a Native American ancestry of Kennewick Man. The genetic evidence adds to evidence that ancestors of the New World's aboriginal peoples originated in Siberia and migrated across a land mass that spanned the Bering Strait during the last ice age, and undermines alternative theories that some early migrants arrived from Southeast Asia or even Europe.

Return

In September 2016, the US House and Senate passed legislation to return the ancient bones to a coalition of Columbia Basin tribes for reburial according to their traditions. The coalition includes the Confederated Tribes of the Colville Reservation, the Confederated Tribes and Bands of the Yakama Nation, the Nez Perce Tribe, the Confederated Tribes of the Umatilla Reservation, and the Wanapum Band of Priest Rapids.

The remains of Kennewick Man were cataloged and removed from the Burke Museum on February 17, 2017. The following day, more than 200 members of five Columbia Plateau tribes were present at a burial of the remains.
