I read a critique of that and it had me convinced that there was more to it. Bone density was a minor factor according to the research I saw.

The bone density notion has zero scientific value. The diffs between African and European bone densities average out to nil. The swimming thing is much more likely to be a cultural difference. People used to think similar about tennis until arthur ashe and then the williams sisters came along.

It doesn't take much observation to see why. In sports where very little equipment is required Blacks can do well. So running etc has a lot of those folks in it. Swimming, cycling etc requires expensive gear so you see bugger all making it. Then throw in the cultural stuff and again it's down to access. US blacks have access to the equipment of Basketball and excel in it. South American and European blacks have access to football equipments and can excel in it. An obvious one is Ice hockey. Whites completely dominate the sport. Race advantage? Nope, they just have cultural aspirations and access to ice rinks. With a few interesting exceptions it's all about the access. Ditto with IQ differences for the most part, though other selective pressures may be at play.

BTW I have no problem with the idea of racial or more correctly populations differences. Indeed the "we're all the same" notion can be just as scientifically dubious as differences clearly exist from the DNA up, but the extreme/obvious differences are slight, found in non average people in a population and colour is the least of it. EG those long distance lads from places like Ethiopia and Kenya have local adaptations to altitude that mean its more likely that some are gonna be shít hot runners. Sure they're black, but a black population from say Nigeria are going to be left behind by them in a long distance race just as much as a white population from France.

Black sprinters would be another population with some differences. In the majority of cases they're descendants of Africans enslaved in the past, rather than "African Africans" so to speak. This may have been a selection pressure that gives an advantage in sprinting. You see far fewer of them lads and lasses in the long distance events.
