In the first study, researchers led by Eske Willerslev, a geneticist at the University of Copenhagen, sequenced the whole genomes of 34 individuals who lived in Siberia, the land bridge Beringia, and Alaska from 600 to nearly 32,000 years ago. The oldest individuals in the sample -- two men who lived in far northern Siberia -- represent the earliest known humans from that part of the world. There are no direct genetic traces of these men in any of the other groups the team surveyed, suggesting their culture likely died out about 23,000 years ago when the region became too cold to be inhabitable.
Elsewhere on the Eurasian continent, however, a group arose that would eventually move into Siberia, splinter, and cross Beringia into North America, the DNA analysis reveals. A woman known as Kolyma1, who lived in northeastern Siberia about 10,000 years ago, shares about two-thirds of her genome with living Native Americans. "It's the closest we have ever gotten to a Native American ancestor outside the Americas," Willerslev says. Still, notes Ben Potter, an archaeologist at the University of Alaska in Fairbanks who was not involved with the work, the relation is nevertheless distant.
Based on the time it would have taken for key mutations to pop up, the ancestors of today's Native Americans splintered off from these ancient Siberians about 24,000 years ago, roughly matching up with previous archaeological and genetic evidence for when the peopling of the Americas occurred, the team reports today in Nature.
Additional DNA evidence suggests a third wave of migrants, the Neo-Siberians, moved into northeastern Siberia from the south sometime after 10,000 years ago. These migrants mixed with the ancient Siberians, planting the genetic roots of many of the area's present-day populations.

Thanks all.
It only worked for me when I separated the search into two words, not Kinnewickman.
It isn’t a search, it’s a keyword.
Here’s a search link for FR (I think the floor is 2014, but anyway):

Got it.
the link in #38 works, just click it.
Thanks for the link.
I had no idea Free Republic’s archive on this subject was so large.
The FRchives are, just in general, pretty much any topic, scary big! :^)
