I’ll be upfront, I’m posting this to trigger SJWs who visit.
I can hear the screeching from here.
“some questions shouldn’t be asked by science!”
fully modern Homo sapiens emerged in Africa 200,000 years ago. 100,000 years ago, a small group of Africans had a sudden urge to head north. This small group inhabited the rest of the world, with minimal contact with the rest of the Africans who stayed in Africa. Forty thousand years ago, the Caucasoid race broke off from the Mongoloid race.
This means the entire world outside of Africa is largely related, descended from one small tribe of perhaps a few hundred or a thousand. This tribe was obviously already unique, in that it alone had the intrepidity and determination to head north and conquer the world. We, the descendants of this unique tribe, have afterwards been evolving under extremely different, more challenging environments for the last 100,000 years apart from the African race we left behind. 100,000 years under dramatically different environments from a dramatically different founding stock is a long time.
yes, that is the natural consequence of Out of Africa, if you believe in OOA, this is literally true
too much time has passed to be considered the same forensically
selection pressures do affect the entire organism
