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.

A pair of children's teeth that were lost 31,000 years ago in Siberia led scientists to the discovery of a previously unknown population of ancient humans.
These people inhabited northeastern Siberia during the Ice Age and were genetically distinct from other groups in the region, researchers reported in a new study.
The scientists analyzed genetic data extracted from the teeth, along with DNA from ancient remains found at other sites in Siberia and central Russia. In doing so, they reconstructed 34 ancient genomes dating to between 31,000 and 600 years ago, piecing together the puzzle of how Paleolithic humans spread across Siberia, and then crossed over the Bering Land Bridge into the Americas.
The tiny teeth belonged to two unrelated male children and were found at the Yana Rhinoceros Horn Site (RHS) on Siberia's Yana River, a locale that was first discovered in 2001. Though Yana RHS contained thousands of artifacts -- among them stone tools, ivory objects and animal bones -- these teeth are the site's only known human remains.
Together, the teeth and the artifacts are the earliest evidence of human occupation in the region; the teeth also represent the oldest Pleistocene human remains found at such high latitudes, the scientists reported.

In honor of gay pride month, I'd like to point out that the scientist who analyzed the child's tooth is gay.
Yes, they do call him 'the tooth fairy'.
I’m soooooo dead...
Turns out old Kinnewick man is related to an indigenous tribe, and is not european regardless of appearance.
When I see a native American I like to yell, “Go back to Asia!”
I could have sworn a link to that had been posted, must have escaped Google’s eagle eye because it was done on one of the subsequent pages of a longer topic. :^(

Lieawatha should move to Siberia.
A woman known as Kolyma1
That’s amazing. How did they know her name?
Climate change happened 23 centuries ago!
Before humans were burning fossil fuels?!!!
How Can That Be?????????????????????????????
OOPs pardon my math.
(sulks away in embarrassment)
She had a wrongful death lawsuit pending against a local mammoth, one of Avenatti's ancestors had taken the case, and the file had been passed down.
You have a great imagination.
Mammoth used to tell me that too.
Warren: I had a feeling I was going to find my great great...{times 32}....grandparents in Siberia someday.
We are a family again. I feel so close to them (tears welling up).
She left a text on her P phone.
Prehistoric phone.
Is that an apple with a string?
