What's 4,500 years anyway? From the U of Colorado piece...
>The earliest Inupiat Eskimos in northwest Alaska -- the direct ancestors of modern Eskimos thought to have migrated into Alaska from adjacent Siberia some 1,500 years ago...
The "best case scenario" on this one is its inclusion in the report was "probably unfortunate." Or perhaps they dropped a zero...
http://www.akhistorycourse.org/articles/article.php?artID=151>No one knows just when the first Eskimos arrived in Alaska, but it was at least 6,000 years ago. The earliest Eskimos inhabited Southwest Alaska. Possibly more Eskimos came to Alaska about 4,500 years ago from coastal Siberia. Although they do not know for sure, archaeologists speculate that the inhabitants of the coast 8,000 years ago might have been Eskimo people.
>The ancestors of Inupiaq Eskimos, whose presence may be documented by archaeological evidence, arrived in Alaska before 4,000 years ago. Bands of Eskimos moved north and east across Alaska and northern Canada to Greenland around 4,000 years ago.
The DNA evidence I'm reviewing is "fleshing out" this stuff, is generally consistent, and it appears Greenland "Eskimos" descended from earlier Alaska inhabitants (although there's still a lot of debate). Back migration across the Bering Sea is documented, of course, but my view is the reason this artifact "went viral" (I read the story first on MSNBC) is because of its "dramatic sex appeal" as much as any possible historical merit.
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC379174/>The geographic specificity and remarkable intrinsic diversity of D2 lineages support the refugial hypothesis, which assumes that the founding population of Eskimo-Aleut originated in Beringan/southwestern Alaskan refugia during the early postglacial period, rather than having reached the shores of Alaska as the result of recent wave of migration from interior Siberia.
