Map of Early Human Migration
A recent report by BBC on likely interbreeding with the Denisovans (and their abundance in Asia) bolstered the "migration/interbreeding hypothesis" of the origin of diverse nationality of mankind. Clearly the original sociological Negroid, Mongoloid and Caucasoid discreet race groups seem to have been accounted for with the Negroid leading the human divergence from Africa. And that appears to solve my quest for answers to question number 1, supported of course by science and common sense. Why do I have a feeling that faith will solve question number 2?

Sampling human mitochondrial DNA Scientifically
Furthermore, aside from human migration maps produced based on archeological finds and duration of habitation that proves the migration/interbreeding theory, the theory gains further credibility with more recent DNA maps reconstructed, based on the human family tree and the study of maternal inherited Mitochondrial DNA (mtDNA) which have led to the identification of the Mitochondrial Eve (L) . This of course is not to be confused with the origin story; as it reveals just statistical frequency of occurrence of the most ancient commonly traceable matrilineal ancestor. Not to say prior ancestors don't exist. How? Of course, that is the search that is still on.
I guess a further study of the human mitochondrial DNA haplogroup tree perhaps will help scientists and sociologists investigate diseases, and development issues with modern man respectively. I will be interested in investigating of course, no matter how cynical or distasteful it might be, the correlation between being evolved on the DNA tree or being with fairly primitive DNA and how that correlates to the human development index. Heck, all the developing countries seem to have high frequency of L0 to L6 just from a quick glance at the DNA evolution tree. More developed nations, except those in Americas, have the later evolved genes. Hmm, explains why USA can't get to keep it together? Too many under evolved genes in Texas perhaps.
May be it explains why Gbagbo cannot just relinquish power...an under evolved African perhaps.
