There certainly are differences, but most of them are fairly superficial. And, as I said, most of the significant differences are between populations within Africa (though the sickle-cell anaemeia adaptation, for instance, seems to be only a few thousand years old). The point, I guess, is that human morphology can respond fairly rapidly to evolutionary pressures - on the scale of mere centuries or millennia when there is a strong advantage to certain traits - but those adaptations are, as you say, mostly cosmetic. Human populations haven't been separated long enough or consistently enough for more radical divergence (the genetic input of archaic humans - Neanderthals and Denisovans - notwithstanding). |
