Sorry. By “Originals” I meant the very first wave of people to the Americas.
Don’t most indig tribes in the Americas have story/legend/myth about peoples that were here before them? If they do, some of that could be from conquest and replacement by members of the same colonization wave that had separated long enough prior that they didn’t know the common source, but some of it also could be conquest and replacement of totally different sourced peoples.
There were no people before them that anybody knew about.
At the same time there's a MtDNA gene sequence (on the maternal side) that links the Sa'ami and Berbers, and quite amazingly the Yakut. There are some other minor bridges and links from these same groups to other far-flung groups.
Look at the Yakut connection closely. This is the founding population for virtually all American Indians, all Eskimos, the ethnic group in Siberia that invaded and conquered Korea and Japan in the 6th century AD, and India in the 3rd/2nd century BC (see my earlier notes on Buddha's family).
Which means two things ~ the maternal line of the first Europeans to leave the Western European Refugia along the border of modern Spain and France really got around ~ and also that the emigration of people from Asia AFTER the 10th millenium was a far more important contributor to modern American Indian populations than emigrations before that time, or after the 6th millenium.
Always remember, genes flow where they will oblivious to culture.
