Linguists or Nationalists: Who was Right About the Origin of Indian Civilization?

A CENTURY and a half ago linguists invented a new map of the world. Their research showed that a single family tree stretches its branches almost unbroken across most of Eurasia: from Iceland to Bangladesh, most people speak languages descended from “Proto-Indo-European”. The philologists had a theory to explain why Sanskrit, the ancient forebear of Hindi, has closer cousins in Europe than in south India. They speculated that at some point before the composition of the Vedas, the oldest texts of Hinduism, an Aryan people had migrated into India from the north-west, while their kin pushed westward into Europe.

Long before the Nazis dreamed of an exalted master race, imperialists seized on what some dubbed the “Aryan invasion” theory to paint Britain’s rule of India as the extension of a “natural” order. Indians, too, found a use for it. Caste-bound Hindu conservatives declared that the paler-skinned intruders must be ancestors of higher-caste Brahmins and Kshatriyas. Such talk stirred a backlash in southern India, where generally darker-skinned speakers of Dravidian languages were urged to see themselves as a separate nation.

Hindu nationalists took a different tack. The West, some said, had made up the theory to set Hindus against each other. Christian missionaries and communists were using it to stoke caste hatred and so to recruit followers, they claimed. Worse, the theory challenged an emerging vision of Mother India as a sacred Hindu homeland. If the first speakers of Sanskrit and the creators of the Vedas had themselves been intruders, it was harder to portray later Muslim and Christian invaders as violators of a purity that good Hindus should seek to restore. So it was that some proposed an alternative “Out of India” theory. This held that the original Aryans were in fact Indians, who carried their Indo-European language and superior civilisation to the West.

An accumulating pile of research using DNA from both ancient human remains and modern people indicates strongly that, beginning around 2000BC, north-west India was indeed infused with new blood. The newcomers appear to have shared the same roots in what is now southern Russia as did the invaders of a similar-sized peninsula to the west called Europe. Strikingly, too, the genetic markers identifying this group seem to be far more prevalent among modern north Indian Brahmins than among other Indians.

Because of the difficulty in collecting ancient DNA, such research has until recently relied on relatively few samples. But an international team of 92 scholars, including David Reich, a geneticist at Harvard University who has pioneered techniques to analyse DNA more quickly and precisely, is set to publish data recovered from 362 “ancient individuals” from across South and Central Asia. Among their conclusions: there was probably an early migration of agriculturalists into India from what is now Iran, around 4000BC, and this was followed two millennia later—just before the Vedic Age—by a large influx from what is now southern Russia.

How Australia’s Pama–Nyungan Language Family Conquered the Continent

A family of languages spoken by ancient and modern hunter-gatherers rapidly replaced other tongues as it swept the Australian continent more than four millennia ago, modelling work suggests.

Australia’s Pama–Nyungan language family includes more than 300 languages, which are spoken across 90% of the continent. Twenty-seven other language families are restricted to the far north. Previous genetic and linguistic studies have led to competing theories about how Pama–Nyungan rose to dominance.

To help resolve this mystery, Quentin Atkinson at the University of Auckland in New Zealand and his colleagues used a statistical method to analyse the shared roots of 200 words across 306 Pama–Nyungan languages. Their findings suggest that Pama–Nyungan spread quickly from north-central Australia to the rest of the continent about 4,500–7,000 years ago.

Dravidian Language Family Dates From 4,500 Years ago

The origin of the Dravidian language family, consisting of about 80 varieties spoken by 220 million people across southern and central India and surrounding countries, can be dated to about 4,500 years ago. This estimate is based on new linguistic analyses by an international team, including researchers from the Max Planck Institute for the Science of Human History, that used data collected first-hand from native speakers representing all previously reported Dravidian subgroups. These findings, published in Royal Society Open Science, match well with earlier linguistic and archaeological studies.

Inhabitants of Vanuatu Were Replaced, but Their Language Lives on

The study, published in Nature Ecology & Evolution and led by a multidisciplinary research team at the Max Planck Institute for the Science of Human History (MPI-SHH) together with researchers in France, Australia, New Zealand, Germany and Vanuatu, reveals that migrations of people from the Bismarck Archipelago in Oceania to the previously settled islands of the Pacific began as early as 2,500 years ago, much earlier than previously thought. The Remote Oceanian island nation of Vanuatu is the gateway to the rest of the Pacific and understanding its demographic history is critical to uncovering that of the wider region. The earliest inhabitants of Vanuatu, arriving about 3,000 years ago, were the Lapita peoples who spoke a form of Austronesian language and who had largely East Asian genetic ancestry. But Vanuatu's contemporary population has largely Near Oceanian heritage, showing that over time the genetic ancestry of the early inhabitants was mostly replaced by that of Bismarck Archipelago migrants, who began arriving very soon after initial settlement. Yet the original Austronesian language persisted and over 120 descendant languages continue to be spoken today, making Vanuatu the per capita most linguistically diverse place on Earth. Vanuatu therefore presents an unprecedented case, where a population's genetic ancestry but not its languages were replaced. Through analyses of new ancient and modern genome-wide data, the researchers show that rather than occurring in one wave, the genetic replacement was long and complex, likely the result of a sustained long-distance contact between Near and Remote Oceania. This provides demographic support for a model from historical linguistics, in which the initial Austronesian language of Vanuatu survived by being continually adopted by incoming Papuan migrants.

The Austronesian Expansion, which began around 5,500 years ago likely in modern-day Taiwan, was the most geographically extensive dispersal of farming peoples in prehistory, ultimately carrying people as far west as Madagascar and all the way east to Rapa Nui. These seafaring Neolithic people initially expanded out across Island Southeast Asia, carrying farming technology and a major branch of the Austronesian language family, eventually reaching Near Oceania where they encountered the indigenous Papuan peoples of New Guinea and the Bismarck Archipelago. The initial settlement east beyond the Solomon Islands and out into Remote Oceania only began around 3,000 years ago, with Austronesian-speaking groups associated with the Lapita pottery culture rapidly expanding east out to Vanuatu, New Caledonia, Fiji and the islands of Western Polynesia. A previous ancient DNA study of Lapita burial sites has shown that these earliest inhabitants had East Asian ancestry with negligible evidence of Papuan genetic admixture. But the present-day genetic make-up of Remote Oceania suggests at least some degree of Papuan ancestry, meaning there must have been subsequent Papuan migration and admixture into the Pacific from Near Oceania.

The Copper Age Iberian Bell Beaker Culture Exported Culture & Technology, not Genes

Prehistoric Iberians 'exported' their culture throughout Europe, reaching Great Britain, Sicily, Poland and all over central Europe in general. However, they did not export their genes. The Beaker culture, which probably originated in Iberia, left remains in those parts of the continent. However, that diffusion was not due to large migrations of populations that took this culture with them. These are the conclusions of an international study in which the Spanish National Research Council (CSIC) was involved. Its findings, published in the journal Nature, indicate no evidence of any genetic outflow from Iberia to those areas has been discovered. "Therefore, the diffusion of the Beaker culture from Iberia is the first example of a culture being transmitted as an idea, basically due to a question of social prestige (since it was associated with the virtues of being virile and of being warriors), which is why it is adopted by other populations", indicates researcher Carles Lalueza-Fox, from the Institute of Evolutionary Biology, a mixed research centre run by CSIC and the Pompeu Fabra University, in Barcelona, Spain.

Between 4,700 and 4,400 years ago, a new type of bell-shaped beaker pottery was introduced throughout western and central Europe. For more than a century, archaeologists have been trying to determine whether the spread of this beaker pottery - and the (Beaker) culture associated with it - represented a large-scale migration or whether it was due simply to the exchange of new ideas. Now, this new study, which includes DNA data from 400 prehistoric skeletons collected from sites across Europe, resolves the debate of whether the spread was due to migrations or ideas, indicating that both arguments are correct. The findings show that the culture which produced these bell-shaped beakers extended from Iberia to central Europe without a significant movement of populations, although the Beaker culture would spread to other places through migrations at a later date.

The study, whose first author is the Spanish researcher Íñigo Olalde, a geneticist at Harvard Medical School, shows that once the (Bell) Beaker culture reaches the centre of Europe (around Germany and its surrounding area), it expands backwards to other places, notably to the British Isles. Yet, in this case, it does represent a migration, replacing around 90% of the population with it. "That is to say, the Neolithic people who built Stonehenge (and who had a greater genetic similarity with Neolithic Iberians than with those from Central Europe) almost disappear and are replaced by the populations from the Beaker culture from the Netherlands and Germany. This replacement is almost absolute in terms of the Y chromosome, which is transmitted by the paternal line, indicating an extreme reproductive bias, and therefore a previously unheard of social dominance. The backward flow also reaches other places such as Italy (at least in the north) and Iberia. I believe it is possible that this is also associated with the expansion of the Celtic or Proto-Celtic languages," Mr. Lalueza-Fox points out.

Infant Head Shaping in PreColumbian Andes Examined

The idea of binding and reshaping a baby's head may make today's parents cringe, but for families in the Andes between 1100-1450, cranial modification was all the rage.

Like Chinese foot binding, the practice may have been a marker of group identity. Its period of popularity in what is now Peru, before the expansion of the Inca empire, was marked by political upheaval, ecological stress and the emergence of new cultural practices. In a study published in Current Anthropology, Matthew Velasco, assistant professor of anthropology at Cornell University, explores how head-shaping practices may have enabled political solidarity while furthering social inequality in the region.

Velasco analyzed hundreds of human skeletal remains from multiple tombs in the Colca Valley of highland Peru and discovered that before 1300 most people did not have modified heads. He found that the number of individuals with cranial modifications increased over time, from 39.2 percent to 73.7 percent during the later portion of the Late Intermediate Period.

Skeletal samples of two major ethnic groups showed that the Collaguas employed methods to make their heads assume a longer, narrower shape, while the Cavanas sought to make their heads wide and squat. Eventually, the elongated head shape of the Collaguas became the predominant style of modification in the upper Colca Valley. According to Velasco, this shift toward embodying a shared identity may have strengthened ties between groups engaged in protracted conflict with outsiders, including the Incas.

"The increased homogeny of head shapes suggests that modification practices contributed to the creation of a new collective identity and may have exacerbated emerging social differences," Velasco said. "Head shape would be an obvious signifier of affiliation and could have encouraged unity among elites and increased cooperation in politics."

Massive open-access database on human cultures created

An international team of researchers has developed a website at d-place.org to help answer long-standing questions about the forces that shaped human cultural diversity.

D-PLACE - the Database of Places, Language, Culture and Environment - is an expandable, open access database that brings together a dispersed body of information on the language, geography, culture and environment of more than 1,400 human societies. It comprises information mainly on pre-industrial societies that were described by ethnographers in the 19th and early 20th centuries.

The team's paper on D-PLACE is published today in the journal PLOS ONE.

"Human cultural diversity is expressed in numerous ways: from the foods we eat and the houses we build, to our religious practices and political organization, to who we marry and the types of games we teach our children," said Kathryn Kirby, a postdoctoral fellow in the Departments of Ecology & Evolutionary Biology and Geography at the University of Toronto and lead author of the study. "Cultural practices vary across space and time, but the factors and processes that drive cultural change and shape patterns of diversity remain largely unknown.

Tracking African Migrations of People Through the Last 4,000 Years Through Genetics

Researchers from the University of Oxford have revealed that the genetic ancestries of many of sub-Saharan Africa's populations are the result of historical DNA mixing events, known as admixture, within the last 4,000 years.

Their study, to be published in the journal eLife, uncovers signatures of these admixture events through a large analysis of DNA from populations across the continent. The discovery provides a foundation for the recent genetic history of the continent, which could aid future studies of non-communicable and infectious diseases, such as malaria.

While admixture has been demonstrated in other regions of the world, the new analysis has allowed the team to characterise sub-Saharan Africa's mixing events in an unprecedented level of detail.

"As Africa has few written records of its history, it is somewhat unknown what important movements of people generated the populations in the continent today," says lead author George Busby, Statistical Geneticist at the Wellcome Trust Centre for Human Genetics.

"Looking at and comparing the differences in the genomes of people alive today can help us better understand and reconstruct the historical interactions that brought their ancestors together."

India's Bene Israel Appear to Have Jewish Origins Based on Genetic Testing

A new study from Tel Aviv University, Cornell University and the Albert Einstein College of Medicine reveals genetic proof of the Jewish roots of the Bene Israel community in the western part of India. They have always considered themselves Jewish.

"Almost nothing is known about the Bene Israel community before the 18th century, when Cochin Jews and later Christian missionaries first came into contact with it," says first author Yedael Waldman of both TAU's Department of Molecular Microbiology and Cornell's Department of Biological Statistics and Computational Biology. "Beyond vague oral history and speculations, there has been no independent support for Bene Israel claims of Jewish ancestry, claims that have remained shrouded in legend."

Population size fails to explain evolution of complex culture

There is a growing consensus among archaeologists and anthropologists that the size of a population determines its ability to develop as well as to maintain complex culture. This view is however severely compromised by a paper published this week in the Proceedings of the National Academy of Sciences (PNAS) by a research team including technology philosopher Krist Vaesen of the Eindhoven University of Technology.

Archeologists observe a fairly sudden appearance of behavioural modernity, such as complex technologies, abstract and realistic art and musical instruments, some 40,000 years ago, in the Later Stone Age. For decades archeologists and antropologists are looking for an explanation for these and other 'cultural revolutions', and in this way finding the origin of human culture. Since ten years or so the predominant theory says the driving factor would be growing population numbers.

How ritual human sacrifice helped create unequal societies

A new study finds that ritual human sacrifice played a central role in helping those at the top of the social hierarchy maintain power over those at the bottom.

"Religion has traditionally been seen as a key driver of morality and cooperation, but our study finds religious rituals also had a more sinister role in the evolution of modern societies," says lead author of the study Joseph Watts.

Researchers from the University of Auckland's School of Psychology, the Max Planck Institute for the Science of human History in Germany and Victoria University, wanted to test the link between how unequal or hierarchical a culture was – called social stratification – and human sacrifice.

The research team used computational methods derived from evolutionary biology to analyse historical data from 93 'Austronesian' cultures. The practice of human sacrifice was widespread throughout Austronesia: 40 out of 93 cultures included in the study practised some form of ritualistic human killing.

Early Austronesian people are thought to have originated in Taiwan and, as they moved south, eventually settled almost half the globe. They spread west to Madagascar, east to Rapa Nui (Easter Island) and south to the Pacific Islands and New Zealand.

Methods of ritual human sacriifice in these cultures included burning, drowning, strangulation, bludgeoning, burial, being cut to pieces, crushed beneath a newly-built canoe or being rolled off the roof of a house and decapitated. Victims were typically of low social status, such as slaves, while instigators were usually of high social status, such as priests and chiefs.

Cuckoldry: Jared Diamond got THIS Wrong, too

Despite the urban myth reinforced by many a daytime talk show, researchers writing in Trends in Ecology & Evolution on April 5 say the emerging evidence consistently indicates that very few fathers have unknowingly raised children who were not biologically their own. The collective evidence for low rates of extra-pair paternity (EPP) challenges the notion that it pays, evolutionarily speaking, to sleep around, the researchers say.

"Media and popular scientific literature often claim that many alleged fathers are being cuckolded into raising children that biologically are not their own," said Maarten Larmuseau of KU Leuven in Belgium. "Surprisingly, the estimated rates within human populations are quite low--around 1 or 2 percent."

Those rates apparently haven't changed much either, despite the fact that people in the past didn't have access to modern contraceptives.

The Aborignal Australian Y Chromosome Diverged 54,000 Years ago From South Asian

The first complete sequences of the Y chromosomes of Aboriginal Australian men have revealed a deep indigenous genetic history tracing all the way back to the initial settlement of the continent 50 thousand years ago, according to a study published in the journal Current Biology today (25th February 2016).

The study by researchers from the Wellcome Trust Sanger Institute and collaborators at La Trobe University in Melbourne and several other Australian institutes, challenges a previous theory that suggested an influx of people from India into Australia around 4-5 thousand years ago. This new DNA sequencing study focused on the Y chromosome, which is transmitted only from father to son, and found no support for such a prehistoric migration. The results instead show a long and independent genetic history in Australia.

Modern humans arrived in Australia about 50 thousand years ago, forming the ancestors of present-day Aboriginal Australians. They were amongst the earliest settlers outside Africa. They arrived in an ancient continent made up of today's Australia, Tasmania and New Guinea, called Sahul, probably thousands of years before modern humans arrived in Europe.

Five thousand years ago, dingos, the native dogs, somehow arrived in Australia, and changes in stone tool use and language around the same time raised the question of whether there were also associated genetic changes in the Australian Aboriginal population. At least two previous genetic studies, one of which was based on the Y chromosome, had proposed that these changes could have coincided with mixing of Aboriginal and Indian populations about 5 thousand years ago.

Anders Bergstrom, first author on the paper at the Wellcome Trust Sanger Institute, said: "We worked closely with Aboriginal Australian communities to sequence the Y chromosome DNA from 13 male volunteers to investigate their ancestry. The data show that Aboriginal Australian Y chromosomes are very distinct from Indian ones. These results refute the previous Y chromosome study, thus excluding this part of the puzzle as providing evidence for a prehistoric migration from India. Instead, the results are in agreement with the archaeological record about when people arrived in this part of the world."

Dr John Mitchell, Associate Professor at La Trobe University in Melbourne, explained: "Clearly there is keen interest in the Aboriginal community to explore their genetic ancestry and without them this study would not be possible - our first step was to return their results to them, before the scientific article was published. This collaboration in genome sequencing, to explore their ancient history, was made possible by years of engagement beforehand with Aboriginal communities."

Further study is needed to answer questions such as how the dingo did get to Australia and why other people such as the seafaring Polynesians didn't settle on the continent. Expanding the genetic analyses beyond the Y chromosome and to the whole genome will also be necessary to completely rule out external genetic influences on the Aboriginal Australian population before the very recent times.

Only 22% of men in Panama Have Y Chromosomes From the Indigenous Population

The Spanish conquest of the Americas was devastating for native peoples. Many native men died in conflicts with the invaders. Male Spanish colonists often came without their wives and took native women as partners. A new genetic analysis of Panamanian men by a team including a Smithsonian scientist shows this historical legacy: only 22 percent had Y-chromosomes of native origin, even though most Panamanians are of female indigenous ancestry.

Everyone has a pair of sex chromosomes that determine their gender. Females have two X-chromosomes, while males have one X and one Y, the latter inherited from their father. These chromosomes are found in each cell's nucleus. Another genetic component called mitochondrial DNA (mtDNA) is found in cells outside the nucleus. Both males and females inherit their mtDNA from their mother alone. Over time, small mutations accumulate in both mtDNA and Y-chromosomes, allowing scientists to trace their history.

A team of geneticists from the University of Pavia including Antonio Torroni found that among the 408 Panamanian men whose genetics were analyzed, 60 percent had Y-chromosomes that originated in West Eurasia and North Africa (probably mostly from Europe). About 22 percent were of Native American origin, 6 percent from sub-Saharan Africa and 2 percent from South Asia (probably China or the Indian sub-continent). In contrast, a large majority of this group--including nearly all those with Native American, African and Asian Y-chromosomes--had mtDNA of indigenous origin. Among men with Eurasian Y-chromosomes, 13 percent had mtDNA from sub-Saharan Africa and only a very few had European mtDNA.

What Happened to the Anasazi/Ancestral Puebloans of Mesa Verde?

Vultures carve lazy circles in the sky as a stream of tourists marches down a walkway into Colorado's Spruce Canyon. Watching their steps, the visitors file along a series of switchbacks leading to one of the more improbable villages in North America—a warren of living quarters, storage rooms, defensive towers and ceremonial spaces all tucked into a large cleft in the face of a cliff.

When ancient farmers built these structures around the year 1200, they had nothing like the modern machinery that constructed the tourist walkway. Instead, the residents had to haul thousands of tonnes of sandstone blocks, cut timber and other materials down precarious paths to build the settlement, known as Spruce Tree House, in Mesa Verde National Park.

“Why would people live here? That's an important question. It's not an easy place to reach,” says Donna Glowacki, an archaeologist now at the University of Notre Dame in Indiana, as she walks among the ruins. Even more perplexing is what happened after they settled there. The villagers occupied their cliffside houses for just a short time before everyone suddenly picked up and left. So did all the other farmers living in the Four Corners region of the American Southwest, where the modern states of Colorado, New Mexico, Utah and Arizona meet.

All together, nearly 30,000 people disappeared from this area between the mid-1200s and 1285, making it one of the greatest vanishing acts documented in human history. What had been one of the most populous parts of North America became almost instantly a ghost land.

Determining the Lifestyles of PreColumbian Amazonian Tribes Through Linguistics

In my class on October 5, 2015, we talked about how ancestral languages can be reconstructed on the basis of their present-day descendants and how such linguistic reconstructions (particularly reconstructions of the vocabulary) can be used to reimagine the lives of the speakers of such ancestral languages. While most of our examples in class dealt with Indo-European languages (with a brief foray into the Polynesian world), here I would like to present another example where the same sort of socio-cultural reconstruction can be done on the basis of unwritten languages who offer us a rare glimpse into the lives of the their speakers’ linguistic ancestors. This example concerns three indigenous South American language families: Arawakan, Tukanoan, and Nadahup. These languages are spoken in the Upper Rio Negro region, on the border of Columbia and Brazil (see the map on the left adapted from muturzikin.com). The present-day Arawak languages are shown in pale-green, Tukanoan languages are shown in yellow, and Nadahup languages in brown. (The best-known language in the Nadahup family—at least in linguistic circles—is Nadëb, which exhibits the rarest Object-Subject-Verb order, found only in a handful of languages around the world, 4 in the WALS sample.) Of the three families, only the Nadahup is limited to this region, while Tukanoan languages are also spoken elsewhere through South America and Arawakan languages are found from Brazil to the Caribbean.

Eurasian Farmers "Invaded" Africa at Least 4,500 Years ago, 4 to 7% of African Genome is Eurasian

Geneticists have sequenced the first prehistoric genome from Africa: that of Mota, a hunter-gatherer man who lived 4500 years ago in the highlands of Ethiopia. Named for the cave that held the remains, the Mota genome gives scientists their first glimpse into what an African genome looked like prior to many recent migrations in Africa. This ancient Ethiopian highlander is most closely related to the Ari, an ethnic group that speaks Omotic languages in the Ethiopian highlands today. And when researchers compared Mota's genome to that of other Africans, Europeans, and Asians, they got a surprise: Africa is usually seen as a source of outward migrations, but the genomes suggest a major migration into Africa by farmers from the Middle East, possibly about 3500 years ago. These farmers' DNA reached deep into the continent, spreading even to groups considered isolated such as the Khoisan of South Africa and the pygmies of the Congo.

A Theory of Punctuated Subsistence Change?

Toward a theory of punctuated subsistence change

Authors:

Ullah et al

Abstract:

Discourse on the origins and spread of domesticated species focuses on universal causal explanations or unique regional or temporal trajectories. Despite new data as to the context and physical processes of early domestication, researchers still do not understand the types of system-level reorganizations required to transition from foraging to farming. Drawing upon dynamical systems theory and the concepts of attractors and repellors, we develop an understanding of subsistence transition and a description of variation in, and emergence of, human subsistence systems. The overlooked role of attractors and repellors in these systems helps explain why the origins of agriculture occurred quickly in some times and places, but slowly in others. A deeper understanding of the interactions of a limited set of variables that control the size of attractors (a proxy for resilience), such as population size, number of dry months, net primary productivity, and settlement fixity, provides new insights into the origin and spread of domesticated species in human economies.

An Alternate Model for the Growth of PreColumbian Tiwanaku

Multiethnicity, pluralism, and migration in the south central Andes: An alternate path to state expansion

Author:

Goldstein

Abstract:

The south central Andes is known as a region of enduring multiethnic diversity, yet it is also the cradle of one the South America’s first successful expansive-state societies. Social structures that encouraged the maintenance of separate identities among coexistent ethnic groups may explain this apparent contradiction. Although the early expansion of the Tiwanaku state (A.D. 600–1000) is often interpreted according to a centralized model derived from Old World precedents, recent archaeological research suggests a reappraisal of the socio-political organization of Tiwanaku civilization, both for the diversity of social entities within its core region and for the multiple agencies behind its wider program of agropastoral colonization. Tiwanaku’s sociopolitical pluralism in both its homeland and colonies tempers some of archaeology’s global assumptions about the predominant role of centralized institutions in archaic states.

Kennewick Man is Native American, Related to Local Tribes

The ancestry and affiliations of Kennewick Man

Authors:

Rasmussen et al

Abstract:

Kennewick Man, referred to as the Ancient One by Native Americans, is a male human skeleton discovered in Washington state (USA) in 1996 and initially radiocarbon dated to 8,340–9,200 calibrated years before present (bp). His population affinities have been the subject of scientific debate and legal controversy. Based on an initial study of cranial morphology it was asserted that Kennewick Man was neither Native American nor closely related to the claimant Plateau tribes of the Pacific Northwest, who claimed ancestral relationship and requested repatriation under the Native American Graves Protection and Repatriation Act (NAGPRA). The morphological analysis was important to judicial decisions that Kennewick Man was not Native American and that therefore NAGPRA did not apply. Instead of repatriation, additional studies of the remains were permitted2. Subsequent craniometric analysis affirmed Kennewick Man to be more closely related to circumpacific groups such as the Ainu and Polynesians than he is to modern Native Americans. In order to resolve Kennewick Man’s ancestry and affiliations, we have sequenced his genome to ~1× coverage and compared it to worldwide genomic data including for the Ainu and Polynesians. We find that Kennewick Man is closer to modern Native Americans than to any other population worldwide. Among the Native American groups for whom genome-wide data are available for comparison, several seem to be descended from a population closely related to that of Kennewick Man, including the Confederated Tribes of the Colville Reservation (Colville), one of the five tribes claiming Kennewick Man. We revisit the cranial analyses and find that, as opposed to genome-wide comparisons, it is not possible on that basis to affiliate Kennewick Man to specific contemporary groups. We therefore conclude based on genetic comparisons that Kennewick Man shows continuity with Native North Americans over at least the last eight millennia.
