Ancient DNA Links Native Americans With Europe

[Rochefaton]

Here is the article (http://www.sciencemag.org/content/342/6157/409.full).


Now comes a surprising twist, from the complete nuclear genome of a Siberian boy who died 24,000 years ago—the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today's Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or western Asia. The finding suggests that about a third of the ancestry of today's Native Americans can be traced to "western Eurasia," with the other two-thirds coming from eastern Asia, according to a talk at a meeting* here by ancient DNA expert Eske Willerslev of the University of Copenhagen. It also implies that traces of European ancestry previously detected in modern Native Americans do not come solely from mixing with European colonists, as most scientists had assumed, but have much deeper roots.


Willerslev reported that the team was able to sequence the boy's genome, and also to radiocarbon date the bone. The team then used a variety of statistical methods to compare the genome with that of living populations. They found that a portion of the boy's genome is shared only by today's Native Americans and no other groups, showing a close relationship. Yet the child's Y chromosome belongs to a genetic group called Y haplogroup R, and its mitochondrial DNA to a haplogroup U. Today, those haplogroups are found almost exclusively in people living in Europe and regions of Asia west of the Altai Mountains, which are near the borders of Russia, China, and Mongolia.

Very interesting to say the least. If anyone has more in-depth info, please share it.

Very strange conclusions. I have no idea how they came up with those.

Why should he descend from East Asians? East Asians are not Native Americans. East Asians are not ancient North Eurasians, well nobody is, though some may be more than others.

Maybe they know something that has not been published, but I don't know. They're sort of thinking in terms of modern genetic poles and imo it just doesn't work. How can they draw equal lines between this dude and today's Native's.


Researchers have been trying to parse the origins of the first Americans for decades. Most agree that people moved across Beringia, via a vast ice age land bridge (see map p. 410), and began spreading through the Americas, reaching Chile by 14,500 years ago. But the origins of the source populations are not clear, and some archaeologists have even suggested that ancient Europeans crossing the Atlantic were part of the mix (Science, 16 March 2012, p. 1289). Others have contended that early skeletons found in the Americas, such as the 9000-year-old Kennewick Man, show some European features (Science, 10 April 1998, p. 190). In his talk, Willerslev argued that the ancient genome "can actually explain a lot of these inconsistencies," by offering glimpses of prehistoric populations before more recent migrations and other demographic events blurred the picture.

Physical anthropology tells very little about ancestry when you start shooting hooks this far into past times. Actually Mal'ta & Afontova Gora are known for being the first ancient remains with mongoloid features.

The Afontova culture is the name given to one of two Upper paleolithic cultures in Siberia, about 22,000-14,000 years before the present (the other is Mal'ta, although some researchers combine the two). The culture is characterized by a wide variety of edge-trimmed flake tools; and it is followed chrononologically by the Dyuktai tradition. Modern human (i.e., Homo sapiens sapiens) remains from the sites of Afontova Gora II and Mal'ta contain the first evidence of Mongoloid features in Siberia, circa 21,000 years BP.


Yet genetics wise they know seem to be very anti-Siberian/East-Asian.

Native Americans in mtDNA, Y DNA, and autosomal DNA group with other Mongoloids in Asia. Showing no west Eurasian(Caucasian) ancestry except for extremely rare mtDNA X2. There is almost no Mongoloid admixture in Europeans in autosomal DNA. Except ones with known admixture with Mongoloids like Finnish and Tatars. Y DNA R1 over 6,000 years ago was non existent in most of west Eurasia. R1a1a M17 most likely originated in eastern Europe and spread with Indo European languages specifically Indo Iranian and Balto Slavic but maybe partly with others. It did not become widespread and popular like today till 5,000-3,000ybp. R1b most likely originated around the Near east and first arrived in Europe 6,000-10,000ybp as R1b1a2 M269 or R1b1a2a L23. The western European subclade R1b1a2a1a L11 is estimated to be only 6,000-5,000 years old. And spread with Germanic and Italo Celtic language mainly in the bronze age. R1 tells nothing about the overall origin of Europeans or any other western Eurasians it is just a paternal line that randomly became very popular mainly in the last 5,000 years. Y DNA R most likely did not originate in west Eurasians(Caucasians) because all descendants of its grandfather K(Xlt) are exclusive to Mongoloids and Oceania except R. So even if it did originate in West Eurasians its's ancestral form got to them through Mongoloid inter marriage. I am sure this 24,000 year old Siberianhas west Eurasian ancestry in autosomal DNA is not because he had a Y DNA R father but because he had a mtDNA U mother. I really don't see how this connectes Europeans and Native Americans the mtDNA U and west Eurasian ancestry just as likely came from Near easterns as Europeans.

This tells nothing looking at mtDNA, autosomal DNA, and Y DNA Native Americans have no west Eurasian ancestry only sign of any is mtDNA X2. Their facial features are very mongloid Europeans have noticed this since colniel times. Native Americans also have little to no facial and body hair very unlike hairy Caucasins. THey also have form what I know all black hair also unlike Europeans, near easterns, and north Africans who have high amounts of brown hair and are the only in the world. Also I have noticed since I see Native Americans and Near easterns everyday native Americans skin is much darker and a more reddish color. I see no Caucasin traits in Native Americans and there is extremely little DNA evidence they have 1/3 Caucasin ancestry.
