Ancient DNA Links Native Americans with Western Eurasians

Willerslev et al. was supposed to report on the Aznick burial at the Paleoamerican Odyssey.

Here’s his abstract:

A Genomic Sequence of a Clovis Individual

Eske Willerslev

The Clovis complex is by some scientists considered being the oldest unequivocal evidence of humans in the Americas, dating between ca. 11,050 to 10,800 14C yr B.P. Only one human skeleton has been directly AMS dated to Clovis age and found associated with Clovis technology namely the Anzick human remains from Montana. We are currently sequencing the nuclear and mitochondrial genome from this human skeleton in order to address the origins and descendents of Clovis. I will present the results obtained by our international consortium.



Instead, he reported on the Mal’ta burial, which he reports:

“…The team proposes a relatively simple scenario: Before 24,000 years ago, the  ancestors of Native Americans and the ancestors of today’s East Asians split into distinct groups. The Mal’ta child represents a population of Native American ancestors who moved into Siberia, probably from Europe or west Asia. Then, sometime after the Malíta boy died, this population mixed with East Asians. The new, admixed population eventually made its way to the Americas. Exactly when and where the admixture happened is not clear, Willerslev said. But the deep roots in Europe or west Asia could help explain features of some Paleoamerican skeletons and of Native American DNA today. The west Eurasian [genetic] signatures that we very often find in today’s Native Americans don’t all come from postcolonial admixture, Willerslev said in his talk. Some of them are ancient.…”

I have it on good word from an anthropology team besides Waters et al. that the mtDNA testing has been complete for some time. All I was told is the haplogroup of Anzick is a rare, but not unheard of, Native American haplogroup. Native American Hg X2 represents that description.

Now we have this word in from Waters et al.:


“…Results from a DNA study of a young boy’s skeletal remains believed to be 24,000 years old could turn the archaeological world upside down – it’s been proven that nearly 30 percent of modern Native American’s ancestry came from this youngster’s gene pool, suggesting First Americans came directly from Siberia, according to a research team that includes a Texas A&M University professor…”

“Our study proves that Native Americans ancestors migrated to the Americas from Siberia and not directly from Europe as some have recently suggested,”

The Mal’ta burial possessed mtDNA Hg U, which is included in Mhg-R, as is Native American Hg B. Native American Hg X is included in Mhg-N(xR). The two NA hgs have very different migration patterns.

If Willerslev reports that the Anzick burial is mtDNA Hg X*, then reporting the Mal’ta DNA results first may be a maneuver meant to “grease the skids”, so to speak.


Time will tell…
