it's the old nature versus nurture issue.

germans during wwII tried to prove scientifically that germans were the superior race. of course they then had to include japanese because they were allies. they even went as far as to say that germans and japanese were related somehow.

none of the "proof" was actual proof.

as for me I don't believe in one race being suprior over the other. you also can't say one race(more nationality than race) is better at one sports then another. as many pointed out that has more to do with cluture(nurture) then race.

people in the US do not care as much about soccer as in say brazil. but at the same token people in france care more about bicycling but guess who is going to win the tour de france for the 4th times in a row? an american????
