you're wrong about most recent common ancestor, it's ridiculous to think that it was 3K years ago when some populations have never reproduced with Europeans yet and have been isolated for thousands of years
of course you're right if no such population exists but if some tribe on some island never got their women fucked by a white guy it pushes it way back

and it's not even relevant because that's just mixture of genes
for example, blacks are all part white in America anyway, their most recent common ancestor lived like a 1000 years in Western Europe

HOWEVER, since only one half of genes are carried from one parent, over like 40 generations they have 1 / 1099511627776 of the genes of their most recent common ancestor and what's more relevant is what the majority of the genes are

maybe in Africa natural selection favored high muscular strength (high testosterone in males) and in Europe it favored high intelligence
we don't really know if that's the case, but that could be a possibility

despite most common recent ancestor and whatever, there are genes that exist in the human genome that go back 100K years ago that some people have and some people don't because not everyone has the same genetic makeup despite being related (we're all Nth cousins)
