ICE AGES DETERMINED THE RACES
This is my current understanding of the races since ‘caucasian’ doesn’t appear to match the data.
The mixture of early indo europeans and europeans happens in the caucuses, but the indo-european expansion is cultural and technological, while preserving markers of the original peoples of both european and west asian origins.
(I am still getting my arms around this. but we had a too simplistic view of evolution of the races. yes, there are africans (old), coastal peoples (middle), and eurasian peoples(new), but old, middle, and new peoples all continued to evolve in place, and to shift quite a bit in response to the ice age.)
