Asians and Caucasians in cold environments without many predators to fear evolved for impulse control, less day to day intertribal violence, IQ, and stable nuclear families as a means to surviving brutal winters and seasonal food supplies.
Africans in a warm environment full of critters that will eat people evolved for emotional responses that go from 0-100 in a heartbeat, more athleticism, maturing physically at a younger age, and less emphasis on selective longterm mates for winter survival and more emphasis on having as many kids as possible by as many people as possible.
Environmentally it makes sense. Just as dark skin makes sense in Africa but not so much in Ireland or Poland. Over centuries of natural selection you adapt to your environment.
There’s obvious reasons that blacks make great NFL running backs and Asians make great MD’s and none of it has anything to do with racism.
