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.

migration, etc. Plenty of evidence supports ‘pre’ this timeline as well. Topper, etc.
Poor Nephi... dissed again!
...so Elizabeth Warren is really Chinese?
Just and argument over who got here first.
I’m a native American. I was born in Cincinnati...
Yea butt . . . you never heard of the Japanese lost tribe of Israel? Huh? Moroni is really Japanese for . . . uh . . . Planet Kolob Supreme Leader.
Yeah, she's a Japchinkoreomalayacherouteapachetonto. JapchinkoreomalayacherouteapachetontA, sorry . . . she's a female, I guess.
Very interesting, not to say astounding, that the first group went as far as Tierra Del Fuego and the Yucatan (Mayans) as well as northeast— Algonkians. BTW the Algonquians are not just Quebec but northern Ontario northern Saskatchewan and Maine. there is an Algonkian tribe and an algonkian language group which is much larger than the tribe.
I read elsewhere that the Tierra Del Fuegans are of another DNA group, far more robust. And the Mayans look absolutely nothing like the Algonkians. So this is confusing.
Anyone who was here in very small numbers could very easily have had their gene line die out. The Nature study is based purely on DNA testing of several hundred current Native Americans scattered across North and South America; it’s not an archaeological study.

The Euro/native American DNA was most likely from interbreeding between the two groups well after the “discovery” of the Americas.
The X haplogroup being found in the Americas may be from a dual micration (east and west) by asian dna
“In addition, these same researchers have detailed that the mtDNA haplogroup X haplotype present in the Altaians of Siberia is intermediate between Native Americans clades and that of Europeans. As a Russian research group observed, “American Indian and European haplogroup X mtDNAs ... are distantly related to each other”. They propose however not an early European colonization of America, but that Altaians contributed to migrants bound for Europe and America; “The network further suggests that the Altaian X haplotypes occupy the intermediate position between European and American Indian haplogroup X mtDNA lineages”
In 2008 genetics paper on the subject concluded
“Mitochondrial Population Genomics Supports a Single Pre-Clovis Origin with a Coastal Route for the Peopling of the Americas”
“Here we show, by using 86 complete mitochondrial genomes, that all Native American haplogroups, including haplogroup X, were part of a single founding population, thereby refuting multiple-migration models.

The Powhatan Indians of Virginia spoke an Algonquian language. At least three English words are based on words in their language (perhaps a bit garbled from the original form): tomahawk, moccasin, opossum.
Of course. Depends on your belief set. Some believe we are all out of Africa, or Asia, or Eden, etc.
Oh, so they’re not native...they’re Asian Americans.
If you’re born here you’re native.
Brilliant!
“No mention of the Norsemen that came over?”
Which ones, when?
Lief Ericsson and his party came about 1,000 but left a few years later, when they became concerned about the Skraelings.
I am curious about other Nordic explorations/migrations/settlements.

These folks bred like rats to get as far down as the tip of South America and from coast to coast in North America.
And they had short lives too.
