Native American DNA Study Results
There's a report out from the University of California Davis that states Native Americans are descendants of one ancestral Asian population, rather than the product of multiple migrations.
The results of the study show there is a genetic marker called the "9-repeat allele" that was found in 41 populations tested from Alaska to Chile.
Their conclusion is "that the most straightforward explanation for the distribution of the 9-repeat allele was that all modern Native Americans, Greenlanders and western Beringians descend from a common founding population."
However, they do allow for other possible explanations.
"If there had been two or more different ancestral founding groups and only one of them had carried the 9-repeat allele, certain circumstances could have prompted it to cross into the other groups and become widespread."
Certain circumstances, perhaps like one immigrant group being wiped out by another group, and the few remaining survivors being assimilated into the surviving group and producing offspring? I wonder where have I read about that before?
And, of course, they rule out this possibility in their research. Read the full news release here.
"Our work provides strong evidence that, in general, Native Americans are more closely related to each other than to any other existing Asian populations, except those that live at the very edge of the Bering Strait. While earlier studies have already supported this conclusion, what’s different about our work is that it provides the first solid data that simply cannot be reconciled with multiple ancestral populations."
