I'm glad you pointed that out.

The answer to this has to do with the different stages of human migration. Thanks to archaeological and genetic research we know that the first human settlers crossed into North America from North-East Asia some 12,000 years ago. They were people of the already existing mongoloid race, which came to be after many millennia of adapting to the colds of Central Asia.

Though these people expanded extraordinarily quickly across the whole American continent, 12,000 years is not actually a very long time on evolutionary standards. For adapting to their new environment they had time to darken their skin colour but few more changes. This is why Asians and Native Americans have several racial traits in common (straight black hair, flat noses, flat faces...) - not that long ago they were the same race.

Good day /sci/fags. How viable is this?

One of the key components of OOA is

>Homo sapiens ultimately migrated out of Africa and replaced all other human populations, without interbreeding

This seems unlikely to me.
