Two distinct groups from Asia settled in the New World and not one single migration as suggested by previous genetic studies, experts said Monday after comparing the skulls of early Americans.
Paleoanthropologists from Brazil, Chile and Germany compared the skulls of several dozen Paleoamericans, dating back to the early days of migration 11,000 years ago, with the more recent remains of more than 300 Amerindians.
"We found that the differences between Early and Late Native American groups match the predictions of a two-migration scenario far better than they do those of any other hypothesis," they said.
"In other words, these differences are so large that it is highly improbable that the earliest inhabitants of the New World were the direct ancestors of recent Native American populations."
Their landmark research found differences in the cranial morphology that could only be explained by the fact that the last common ancestor of the Early and Late Native American groups came from outside the continent.
The experts agreed the differences were best explained by a scenario in which a first wave of settlers came across the Bering Strait from Northeast Asia followed by a second group from East Asia much later via the same route.
"We conclude that the morphological diversity documented through time in the New World is best accounted for by a model postulating two waves of human expansion into the continent originating in East Asia and entering through Beringia," they said.
"This disparity between our results and those of most genetic studies points to a large gap in our understanding of the peopling of the New World."

This is very troubling from a legal standpoint. What happens when the descendants of the earlier inhabitants want to open up casinos, all the good locations are already taken.
3 times.
I count us because it was no different than any of the other times.
They’ve been doing this for years. The morphology between the ancients and moderns looks different but the genetics say they’re the same. I go with the genetics. Animal studies have shown that morphology can change radically in a few thousand years.
Does this relate to the differences between the Athabascans and other tribes?
Meanwhile, the Caucasian skull recovered from a riverbed in Oregon has been suppressed.
It wasn’t Caucasian but yeah it’s been suppressed.
Excellent, 2 more national holidays!
I’d be curious how the later inhabitants don’t at least have traces of their (first settlers) DNA after thousands of years of probable intermixing. Could that possibly explain the morphology?
So the people who call themselves Native Americans are descended from a group of people who came here and stole the land from its previous inhabitants? :)
Maybe 5 times.
The simple answer is that people had boats, they could travel great distances and were used to doing that, and when you come to America it is exceptionally difficult to GO BACK the other way.
When you are here you are here!
We have many beaucoup Salvadorans around here. They can pass for Yakut/Sakha or Japanese ~ with absolutely no problem. However, they're probably not descended from Japanese because they don't have the molars with the 5 roots (from the Emeshi/Jomon/Ainu in Japan) ~ 40% of modern Japanese have such teeth.)
However, to pass for a group you probably share a substantial ancestry with them ~ in this case that would be the Yakut/Sakha prior to their contact with the Emeshi/Jomon/Ainu and the peoples of the Yayoi culture in Japan (circa 560 AD).
Which raises a good question about the Yakut/Sakha. Did the same group that was able to conquer Korea and Japan (with a technology equal to that of the Chinese) in the 6th Century AD also able to navigate the Pacific to get to Central America?
Odds are good they could, and did, and are still around here.
The way I see it, the only remaining question about American settlement before Columbus is what kind of boats did they use?
That’s one possibility. Another could be rapid evolution caused by extreme conditions and can occur without addition to the gene pool. As a matter of fact this is what happened with Indian dogs oh somewhere around 8000-6000 years ago. They at one time were fairly large but (it’s thought) due to the Altithermal (extreme climate warming) they shrunk to terrier size.
Yeah I’ve long accepted the theory of europeans coming fromn the east with boats. If they came during the glacial period the seas were lower and traces of the earliest arrivals are under water on the continental shelf.
Why else do you think “native americans” screech and demand that any recently discovered skulls be immediately reburied before they can be studied?
I hope someone called Child Protective Services. I just can't imagine irresponsible parents like that -- allowing their kids to sail around the world. Were they looking for a reality show? sarc/off
Wasn’t McCain involved with that somehow ?
Actually I’d be really curious whether their oral traditions secretly contain evidence of the previous inhabitants, or whether that’s been scrubbed.
