Y-DNAHaplogroup Q1a3-M346 along with haplogroup C3-M217 are both considered indicators of Native American ancestry.
Today, members of Q-M242 are found in Siberian populations of Kets (94%), Selkups (66%), Altians (17%), and Mongolians (4%), and Native American populations including Ameridians (9%) and NaDenŽ-speaking groups (25%).
Haplogroup Q1a3-M346, a subgroup of Q-M242, is believed to be indigenous to the Americas, but some back-migration may have occurred since Q1a3-M346 can be found at very low frequencies in Northern Siberia and Central Asia. Another sublineage, Q1a3a-M3 originated about 8,000 years ago in the Americas where it is widespread throughout both continents. It is found in South American Amerind populations at 58%, NaDenŽ populations at 50%, and North American Eskimo Aleut populations at about 46%.
Haplogroup Q1a3a1-M19 is a subclade of Q1a3a-M3 and is restricted to South American populations. The Ticuna population of the upper Amazon (67%) and Wayuu population of Columbia's Caribbean coast (10%) are members of the Equatorial-Tucano linguistic family that share the Q1a3a1 haplogroup.

I'm not an expert in DNA evaluation, but it would seem that the migration of Q1a3 etc. Haplogroups may have taken place over a long period of time and it did not all happen at once. It is my opinion that possibly there were many migrations from Asia to North America and possibly back to Asia. Additionally, these people probably didn’t arrive in the same way, some may have walked other may have come down the coast by small boats etc., both of course following the food chain.
ReplyDeleteWhen these groups arrived, some comingled, other didn't or were isolated, this could explain the difference in Q1a3 and Q1a3a groups. We have just skimmed the surface of DNA genealogical research. As the DNA pool expands a clearer picture of all the groups that came to the Americas by way of Asia will become more settled. We must think outside of the box on such issues and not be predisposed to any on scenario.
Simply desire to say your article is as astonishing.
