The other theory is that the African people who became ancestral to both the Chinese and the Europeans didn't arrive in Europe until about 35,000 years ago (or maybe even more recently).

That makes East Asians and Europeans equally descended from one group of Africans.

That group itself is somewhat removed from the other African groups.

The solution to the Amer-Indian conundrum is simply that North American Indians have a degree of European ancestry from a single group dating back about 14,000 years. Try:http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1199377/

I didn't find any mention of the Sa'ami in this study ~ that's a shame since they appear to have been the first inhabitants of Scandinavia.

Nope an earlier post has them sneaking into Greece.

I looked up She, and found them in China speaking a Hmong-mien language. Are these the same Hmong who helped our special troops in the mountains of Vietnam?

In any consideration of the splite in human subgroups, one must think about the possible impact of the great Toba megavolcano 74,000 years ago. Which way did the major ash fall go, what areas of the world suffered the most from several years of “nuclear winter”? These and related factors must have had a big impact if the human population was reduced to no more than 5 or 10,000 people as some scientists propose to explain the lack of genetic variability.
