So, for my part, I am sure there have been people long before there has been anything like the races or phenotypes that are around today, so there's very little point in concern about the races and phenotypes that exist today where people might have come from millions of years ago. I don't think H. erectus in Georgia were Caucasians or Mongolians, or that H. erectus in Africa were Negroes, so it doesn't make any sense to care about such things regarding the origins of humanity so long ago. Even ~75kya I don't think there were any Caucasians, Mongolians, or Negroes to be racist about, no matter where they might have been living.
Dear @valued-customer !
I have a hard time understanding your excellent academic English, but I agree with you that the first humans were not divided into whites and blacks!
I guess that from the time of Noah's sons Shem, Ham, and Japheth onward, they were divided into whites and blacks!
Thank you for kind answer!
