The reason that (sub-Saharan) Africans look (at least more than the other 3 races) more like simians (monkeys, apes, including the human ape) is that the higher-level simians (i.e., excluding New World monkeys) pretty much all (orangutans excepted) live in sub-Saharan Africa, and thus have detailed features to make heat loss a priority (Indian subcontinent people didn't have enough time to evolve physical features back to that of a hot climate - but they still have evolved to be able take much more heat that anyone else). The irony is that the non-human simians all have lots of hair, and hair is a great heat insulator.
BTW, the reason humans don't have much body hair is that as pair-bonding became much more evolutionarily positive (i.e., because with human intelligence, memes become more important than genes), it was evolutionarily positive for females to hide their estrus (i.e., requiring men to keep giving women provisioning & defense so that they could sex them enough so as to catch the fertile times), but to get to that point, there still needed to be a physical sign that the women needed to attract men, and the bare buttocks became that sign, and losing hair most everywhere else just naturally followed as a result. And with bare buttocks becoming so evolutionarily positive, humans gradually lost body hair. The reason that head hair remained is because the brain needed the best air-conditioning, and the kinky hair of Africans (pre-out-of-Africa migration) basically made the hair the equivalent of swamp coolers, so it was evolutionarily positive for it to remain there; hair straightened out with the other races because they moved into colder climes, and so keeping heat in was the evolutionarily positive adaptation. And I suspect that hair remained in the pubic region because genitals are bit freaky looking.
