    Homo Sapiens first developed in southeastern Africa about 800Kya-1200Kya, then spread to the western shores of Africa about 750Kya. Let's call these people Afrosapiens. They are common to all of us.

    About 600Kya, there began a great migration along the lines of many large African species, northward and northeastward. Low sea levels allowed for the migration to move unimpeded into Europe to the north, and into Asia and Oceania to the east and southeast. When sea levels rose again, these bands of travelers became evolutionarily isolated. Let's call these people Eurosapiens and Asiasapiens.

    About 150Kya, there began a final migration out of Africa to the southeast along the coastlines of Asia, Oceania, and into Australia. These people are still the aforementioned Afrosapiens.

    About 50Kya, the last great human migration occurred that populated the Americas, certainly including Asiasapiens by land from the west, but perhaps also including waterborne Asiasapiens from the far southwest and Eurosapiens and Afrosapiens from the east.

    My thinking is, ultimately, that we are all African in origin, but through migration, geographic isolation, and environmental pressure, the well-known Neanderthal People developed the physical traits that we now associate with Eurosapiens, and that the brand-newly discovered Denisovan People (neither Neandertal nor early modern!) developed the physical traits that we now associate with Asiasapiens, and that Sri Lankans, Andaman Islanders, and aboriginal Australians display the physical traits that we now associate with Afrosapiens.

    But I could be wrong.

    •  I should add that "blending" has occurred -- (2+ / 0-)

      and continues to occur -- all along the periphery of these regions as one band passes by others. We are not separate species, just slightly different breeds of one species, so... yeah, blending!
