I post this in response to Kpete's recent post of the discovery of a new species of Homo;
Breeding with Neanderthals helped humans go global

Secondly, there are major topics that could have been introduced in sub threads.
I believe the discovery of more and more genomes of waves of hominins that left Africa dispels the lingering theory of multiple and simultaneous civilizations arising around the globe. I believe this theory is the result of an underlying racial hatred by those who refuse to believe that they could be ancestors of anything African. In putting forth the theory that there are multiple civilization centers they can say that they are European or Asian or whatever 'race' of humans they are-geocentricism. I believe there can only be one source for the global fact that civilization arose nearly simultaneously across the globe; Homo sapiens' final wave of leaving Africa as recent as 50,000 years ago and interacting and breeding with the hominins that already had left Africa. As bhikkhu stated in a sub thred "Simply put, interbreeding fosters robust disease resistance and better overall health."
