Native Americans spread out today from Canada to the tip of Chile descended not from one but at least three migrant waves from Siberia between 5,000 and 15,000 years ago, a study said Wednesday.
The finding is controversial among geneticists, archaeologists and linguists -- many of whom have maintained that a single Asian ancestral group populated the Americas.
But the new study, claiming to be the most comprehensive analysis yet of Native American genetics, claims to have found incontrovertible proof that there were three immigration waves -- a theory first put forward in 1986.
Most Native Americans, said the study, descend from a single group known as the "First American" which crossed from Asia via the Beringia land bridge towards the end of the last ice age some 15,000 years ago.
Their modern-day descendants include the Algonquin of Quebec, the Yaghan of Tierra del Fuego and the Kaqchikel Maya of Guatemala.
But two later migrations of people closely related to the Han ethnic Chinese were responsible for creating more groups, according to a paper published in the journal Nature.
"Speakers of Eskimo-Aleut languages from the Arctic inherit almost half their ancestry from a second stream of Asian gene flow, and the Na-Dene-speaking Chipewyan from Canada inherit roughly one-tenth of their ancestry from a third stream," it said.
This indicated interbreeding between later immigrants and the First Americans they encountered.
The second and third waves of migrants may have come to America in boats after the Beringia land bridge disappeared under water at the end of the last ice age, human geneticist Andres Ruiz-Linares of University College London's department of genetics, evolution and environment told AFP.

An account by Snorri Sturllasson has it that one group stayed awhile and built a nice longhall. Later two groups came together and ended up fighting over that longhall - with one group killing the other. Mass murder seemed to sour the entire enterprise and they left and went their separate ways.
You do know the noble savage sitting on his horse overlooking his buffalo herds didn’t happen until after the white man brought the horse to the Americas.
Not all Indian Blood Lines arrived at the same time.
So - as I said - it’s just an argument over who got here first.

Hah. Nice little gap between Canada and S. America. Hard to do a 'real' study when you leave out America. Reason, politics.
What about Kennewick Man..
What IF they have the entire history of man bass ackwards and all DNA that matches up from them to us started with us?
Lenni Lenape means Original People. What if europeans and asians descended from migration FROM here TO there and not the other way around?
I myself am of the Sosumi in NY, thought there are many Wattsituyas and Fugawes..
These theories keep changing. Before history was put in writing, there was lots of migration between lands and people.. Many academics fall all over themselves to avoid the possibility that various Caucasian peoples were in the mix..
Good find! Thanks!
I am interested in the times of these 3 migrations.
Do you know of some articles that might supply some time data?
If so, please ping or FRmail me.
Thanks.

So they’re not “Native Americans” after all.
the norsemen didn’t leave any genetic remnants — it was probably a short-lived colony. I’ve never heard of the Cherokee with European DNA — do you have any links that I can refer please?
the thing is what to call “native Americans” then. They’re not Indians.
Either way, it seems they were doing it 9000 years before there was light, or so it would seem.
Well, there are NO monkeys which are native to North America so ‘science’ figures no ‘people’ could actually have ‘evolved’ here.
Any anthropological academics today exists primarily to discredit whites of anything except atrocity
well, no need to breed like rats. A regular birth rate would account for the spread over thousands of years.
