thanks for the posting, Blam.
Do you hae a link to that recent map that showed DNA tracing of Amerindian ancestor crossing and then re-crossing the Bering Strait?
I forgot to put it on ‘Favorites’.
It is clear and obvious there were many migrations. The Maya of Yucatan peninusla are very different from the Plains Indians.
Plains people and the Woodland peoples must have more of the X and A2 lines.
I am assuming by ‘Ainu’ you mean the robust B lines.
