I think it was Nova a while back that suggested that clovis technology came from a stone age french tribe, and that there were traces of them in the genes of eastern native americans.
My understanding is that it is roundly rejected by almost all archaeologists.

Geneticists sequenced the DNA from a young boy's 13,000-year-old bones found in Montana. His DNA matches a specific combination of Eastern Asian and Siberian DNA that is found in all North and South American native populations, and only in these populations. This lends to the theory that the first people to permanently settle the America's (Clovis) were made up of groups from Siberia and Eastern Asia combining and crossing the Bering Strait.
Wouldn't that make the boy a member of the clovis culture and not the pre-clovis one being discussed?
I was replying to WalterBright's comment mentioning the Clovis culture coming from what is now Europe.
