Ancient DNA Reveals a Completely Unknown Population of Native Americans (sciencealert.com)

schwit1 shares the findings of a new study of 11,500-year-old bones: Sunrise girl-child ("Xach'itee'aanenh T'eede Gaay") lived some 11,500 years ago in what is now called Alaska, and her ancient DNA reveals not only the origins of Native American society, but reminds the world of a whole population of people forgotten by history millennia ago. "We didn't know this population existed," says anthropologist Ben Potter from the University of Alaska Fairbanks. "It would be difficult to overstate the importance of this newly revealed people to our understanding of how ancient populations came to inhabit the Americas." In a new study published this week, the team reports that a genetic analysis of sunrise girl-child's DNA shows she belonged to a forgotten people called the Ancient Beringians, unknown to science until now. Before now, there were only two recognized branches of early Native Americans (referred to as Northern and Southern). But when the researchers sequenced sunrise girl-child's genome -- the earliest complete genetic profile of a New World human to date -- to their surprise it matched neither.

Given the nature of this field of research -- and the scope of the new findings -- it's unlikely the new hypotheses will remain uncontested for long. But in the light of all the new evidence researchers are uncovering, it's clear the first settlers of America carried a more diverse lineage than we ever realized. "[This is] the first direct evidence of the initial founding Native American population," Potter says. "It is markedly more complex than we thought." The findings are reported in the journal Nature.

    Also, perhaps the second wave passed through Beringia as travelers or refuges, not as conquerors, since they had large numbers but didn't displace the early wave. So not only did the "pause" happen, but the pause culture was likely very strong and outlasted the second migration, perhaps lasted until the local conditions changed.

    Judging by the date these are a hitherto unknown group of 'Clovis' people but Clovis is more of a cultural and temporal designation than a genetic one. Clovis (oversimplifying here) is currently a label that is stuck on any group inhabiting the Americas between ~15.000-11.000 years ago and that used a particular style of cultural artefacts and (mostly) their stone tools (because stone tools and garbage piles is usually all we ever find). Thus Clovis is a cultural grouping that does not map directly to a distinct genetic population any more than all modern humans who use claw hammers, wrenches, files, soldering irons, ... etc belong to the same genetically distinct population since humans readily adopt new cultures and abandon old ones if they see an advantage in it. Walk the streets of Tokyo or Shanghai, and you won't see many people in Edo or Qing dynasty period clothes. The locals have all abandoned their traditional clothing culture for European/American style clothing culture for the most part while we here in America/Europe have supplemented much of our food culture with Oriental food culture. The majority of the early Native Americans were of Asian descent while a smaller group among them may have come from a population in Siberia with some genetic affinity to populations that settled Europe but that population has died out in Asia and was swamped by later immigration waves in Europe. If I'm understanding this correctly the early settlers of N-America split into two populations with one group staying in Beringia while the rest migrated into N-America where that group then split once again into the distinct northern and southern branches of Native-Americans. The Beringians were then later swamped or absorbed by immigration waves coming back up into Canada and Alaska from the south out of North America. What is interesting about these results is firstly that they indicate a single settlement wave that gave rise to all modern Native American populations and that the DNA seems to indicate immigration into the northern most parts of North America began over 20.000 years ago. This can either mean those people were pre-Clovis if they used that tool culture or alternatively that Clovis can be pushed back to over 20.000 years ago just like 'Ötsi' the ice mummy found in the Alps some years ago pushed back the beginning of the copper age in Europe by about a thousand years.

The Monte Verde site in Chile is quite securely dated to 14800 BP ; 15500 is an educated guess. However, this fossil is from 11500 years BP, over 3000 years later.

The DNA test results had the triplets differing from each other by more than 10%, which is a greater difference than the 7% genetic difference between humans and monkeys, the 3.1% difference in DNA between humans and orangutans, and the 1.2% difference between humans and chimps.

Well, it is science. It’s done by scientists, and it’s done on DNA samples. And it produces real data.” But these companies simply don’t have enough comparative information to pinpoint a gene on a world map.

    Morgan not only confirms what the anthropologists say — that the DNA tests are not as accurate and precise as they are claimed to be — he also reveals other problems, such as test results being “tweaked” to conform with the customer’s expectations because “It pays to suck up to the people who pay you,” and test samples being contaminated because the customers sent their saliva mixed with other substances, such as food or saliva from another person.

    Most egregiously, Morgan also confides that his DNA testing company has faked African ancestry for customers deemed to be racists:

    “I only know of two times somebody wanted to be tested for being another ethnicity because they didn’t like that ethnicity. Both times, [they were] white people not wanting to believe they had black ancestors. []

    [One customer] wrote to us asking what that meant, and we wrote back that it meant it was under 1 percent. And we were not saying zero.

They really don't want the companies that release full genetic maps to associate those with medically useful information. Many people have done so successfully however, identifying risks in time to treat them while they are still very minor.

      One argument I see against genetic testing is that it might identify a high risk you will die from something. This seems like a young person's concern to me. Most everyone I know now is planning for death and has a pretty good idea of their likely maximum life span (mine's about 78). Genetic testing (by a doctor) revealed several genetic issues I have which affected my medications. The biggest is that I can't use regular B vitamins very well. My body doesn't "folate" them properly so I have much better results from folated B vitamins.

What's even less intuitive is that, according to Chang, how many people from history - like the two early North American infants - appear to have no living descendants today, per the linked article:

    Chang’s calculations get even weirder if you go back a few more centuries. A thousand years in the past, the numbers say something very clear, and a bit disorienting. One-fifth of people alive a millennium ago in Europe are the ancestors of no one alive today. Their lines of descent petered out at some point, when they or one of their progeny did not leave any of their own. Conversely, the remaining 80 percent are the ancestor of everyone living today. All lines of ancestry coalesce on every individual in the 10th century.

    If that's the case after just 1,000 years, it seems quite reasonable that many, many, more lines would have existed and died out in the preceeding 10,000 or so. Especially if you were to start factoring in the more tribal nature of communities and the increased susceptibility to famine, disease, conflict, natural disasters, and so on that results.

    When you say "line died out" you're using an inappropriate metaphor for the evidence. Because of meiosis in each immediate descendant a random half of the genes of each of the parents are not included. When a small population is absorbed by a larger population, this can easily, over the generations, result in all unique genes not passing through, even if they all have living descendants.

I understand (from the article) he used numerical analysis to make an estimate of how people mix, and I accept it's true if you go back farther (for example, 700s), but 600 years seems too short just based on empirical evidence.

    I also have serious doubts about 3,400 years for everyone in the world......some of the populations were isolated for 10s of thousands of years (Australian aborigine, for example), and 3,400 years seems too short. If he'd said most people share an ancestor from 3,400 years ago, that would pass the "smell test," but statistically there is high probability of straggling communities who are a bit isolated.

    That's where the geneticists come in, and this is covered in the article too. Even in *extremely* remote tribes - those in Brazil, for instance - there is genetic evidence of interbreeding with adjacent tribes, who interbreed with their adjacent tribes, and so on. Just because Tribe A has never mingled directly with true outsiders, doesn't mean their cousins in Tribe B, don't have cousins over in Tribe C that don't do so; by land for the Amazonian tribes, by sea (Polynesians, etc.) for the Aborigine. Once you start factoring in breeding by wider-ranging performers, traders, explorers, and (of course!) militaries and raiders, it starts becoming more and more likely that no one is truly isolated from everyone else for long. Obviously Chang's work is just a mathematical model and his numbers are the result of that, but it does seem to correlate very closely with genetic evidence so, while there will always be outliers, for the majority of the global population at least he's probably not all that far out of the ball park.

    Although the triplets all came from the same womb, they got wildly different results from both companies.

    The fact is, this is normal! They are siblings and siblings often share less than 25% of their DNA with each other. Each person receives half of their autosomal DNA from their mother and half from their father. But the DNA doesn't come in "halves", it comes in little bits, a bit from here and a bit from there, so siblings definitely do not get all the same DNA.

    In theory, siblings can share almost none, or almost all, of their autosomal DNA. The process is entirely random and on average, it is 25% shared (0.5 x 0.5). This is a simple problem in probability which one can't expect any journalist (let alone the average person) to understand.

      You are right; I misspoke.

      What I am talking about is shared patterns in the autosomal DNA, patterns formed by segments of identical strings of single nucleotide polymorphisms (SNPs). The longer the segments of identical patterns comparing person A with person B, the more likely they are to share a close genealogical relationship. If the pattern is broken by person A having a different SNP at some location or missing an SNP that the other person has, then the shared segment is shorter than it might have been otherwise. On average, siblings share about 25% of their total autosomal DNA. The parts that they don't share are comprised of segments (from the same parents) that were constituted differently. One got segment xyz from their father while the other got segment xyz from their mother. That is the key, what segments each sibling received from the mother or from the father. It is random.

      and every egg is identical

      Bzzzzt! Genetics exam failed. Go back and re-do your genetics course.

      During meiosis (chromosome reductive cell division; not regular cell division - that's mitotis), each chromosome splits into two haves, then split at number of points within each chromosome ("crossovers") . The segments between crossover points then randomly switch to one daughter chromosome copy and to another. If both alleles of a gene in a crossover segment are the same, then you'll get indistinguishable products, but otherwise one allele will go to one pair of product gametes, and the other will go into the other pair of gametes. That is essentially random. It's why we have sex. Neither eggs nor sperm are identical.

      There are 26 chromosomes, so even without crossovers there are about 67 million possible outcome eggs from one genome, even without the additional within-chromosome crossover points. Most of them will be broadly similar (because most alleles have very similar functions in either sequence), but it's what makes the difference between, for example, your immune system's behaviour and your identical twin sister's immune system.

      The same argument applies to sperm, of course. And a larger environmental effect, since egg formation takes place while the foetus is buffered by the mother's immune system, while most men go on making sperm until pretty close to death.

      not so much whether stuff is switched on or off but how much it is switched on or off, what they used to call junk DNA.

      That would never have been called junk DNA. It would have been called "regulatory DNA". Not even non-coding DAN (since it codes for a ribosome that regulates the action of other genes by binding to a locus which either prevents or promotes initiation of expression of that gene.
