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.

Have they done DNA analysis on Kinnewick Man?
First time I have heard that.

They knew about the Kennewick man error fairly soon after discovery. Once the original forensic anthropologist found out they were ancient bones he knew and backtracked.
I call them Tribal Americans. (I am a Native American, whether they acknowledge it or not.)
I do not mind the term, Native American Tribe, being applied to them. I do mind the usurpation of the term, Native American, being exclusively applied to them.
(Full disclosure: I am more than 1024th Tribal American on my father’s side. So what? I am a Natural-Born Citizen of the USA, and therefore a Native American.)
Could it have anything to do with walking across an ice bridge between Big Diomede Island (Russia) and Little Diomede Island (Alaska / North America)? They’re that close together. You CAN see Russia from Alaska.
That’s 230 centuries. 23 would only be 2300 years.
I agree that the age of the bones was resolved almost immediately.
The major issue was the origin of the bones - Europe or Siberia - which would have challenged the Siberian Land Bridge theory.
My recollection was that no DNA could be extracted because the bones were in wet sand for thousands of years.
I had completely forgotten about the analysis done in Denmark.
I Googled up a Seattle Times article written three years ago and refreshed my once very good memory.
As I recall, the original Denmark researchers could only assemble a partial DNA profile because the bones laid in wet sand for thousands of years, so their conclusions were by no means definitive.
I also forgot that the scientist who led the lawsuit to preserve the bones for research concluded that the bones belonged to person with a maritime or coastal diet - heavy in salt water fish and crustaceans - which was completely at odds with the discovery of the bones hundreds of miles away from the Pacific.
As soon as they knew the bones were ancient they sent them for a detailed examination which came up with no affiliation with any modern people but the closest affiliation was with a southeast Asian group. That and the age and the rest of the find placed them in the paleo-indian group.
The recent DNA test merely confirmed all the other evidence.
I thought they carbon dated them shortly after discovery.
Anyway, the issues, as I recall, were that the skeleton did not resemble paleo-Americans, plus, the bones revealed a coastal or maritime diet, that was hundreds of miles away.
I also read an article in National Review in the 1990s that disclosed that significant parts of the skeleton had “disappeared” from the lab, and that the skeleton had been handled by un-gloved tribal elders
I'm a science and technology guy, so I was very disturbed that something this rare would have to be turned over to self-identified Native Americans with no known relationship to the bones, instead of being available for continued research and museum display.
And if I’m recalling correctly, Clinton had the site of the discovery plowed under, then paved. Thank goodness it’s only aboriginals who get upset when science intersects with their myths. Oh, wait...
That's so depressing.
Many years ago I recall reading that pre-Columbian skeletons, or even bone fragments, are incredibly rare, but I do not recall the exact numbers.
“that the skeleton did not resemble paleo-Americans”
I think that was “did not resemble Native Americans”. Which was part of the original erroneous description. Paleo people looked different than their descendants. They could also travel further than a lot of people believe.
If tribal elders handled the bones that can only be because of NAGPRA. They don’t have a cultural affiliation but the DNA test showed he’s related to the local tribes. I think that’s really interesting.
It was done to placate the Aboriginal fears the we might still find something at the site proving they weren’t the first people here.
Obviously they needed a single-payer health plan.
NAGPRA is an anti-scientific abomination and should be repealed. Every single word. In the case of the Kennewick Man, the research into the remains was screwed for years because of federal interference contrary to NAGPRA. The whole matter would have been settled sooner and more information would have been available if the fed a-holes had sat down and STFU.
Regardless, this topic isn’t about Kennewick Man, but there are great topics specific to the remains:

I wholehearted agree.
