Thanks for that Soilguy. However we know from other species that mtDNA doesn't necessarily reflect nuclear DNA. There is a relevant site by Bradley et. al. on African, European and Indian cattle but SAGG site won't accept the reference I have. I'll try to find it somewhere else.

In the Out of Asia posting I put in a reference to Y-chromosomes of American indians. In it Karafet writes "each gene has its own evolutionary history" The original Out of Asia posting gives examples of human genes that show ancient regional ancestry. This shows there have been regional contributions to the human genome long before the "Out of Africa" migration. These contributions probably include Neanderthal as well as Southeast Asian Homo erectus and Pekin Man.
