I read an article that the top 200 times for the 100m (prior to Athens)were all held by black atheletes that whose ancestors had originally come from West Africa.

The same is true for almost all running events. Because one Caucasian and one Asian got the gold in two (of many) running events does not disprove there are small genetic differences in subpopulations that do not have unlimited gene flow with other populations.
Everyone in the Olympics is a genetic freak. That is a fact. Everyone in the Olympics (except the USA basketball team) are genetic freaks that train exceptionally hard and exceptionally smart. So if we assume we already have the outliers in every population in regards to genetic potential and training intensity, then no nation with a large population should ever have an edge over any other nation. If all genetics were more or less equal, then the results every Olympics would be more or less random. However, Africans, or their descendents, win nearly every medal in every running event. What, there are no white guys in America that like to run and want to be in the Olympics? Sure there are. Jeremy Wariner, for example. In fact, he may well turn out to be the fastest 400m runner of all time. But every other guy medalling in that race, or close to medalling is not white. Wariner won because of super freaky genetics. But the fact that there are simply no other white guys winning those races suggests that Wariner’s freaky genes are much rarer among whites than blacks.
The other thing to keep in mind is that the differences we are talking about are relatively small. We’re talking about maybe .5 seconds on average that separates an elite white sprinter from an elite black sprinter. They both train equally. 0.5 seconds is due, not to environment, but a very small genetic difference, probably a single allele. There have been many, many genes found with differeing frequencies among human populations. It is nothing surprising. That people would then assume that genes for muscle fiber composition, for instance, would be invariable over every human population, while every other gene varies, is being willfully ignorant of population genetics. It can’t happen. Either all genes vary in sub-populations with limited gene flow or no genes vary (except due to mutation). You can’t invoke some new laws of genetics because it suits your politically correct ideology.
We can turn the problem around–why are there no blacks winning medals in swimming? Sub-saharan Africans on both coasts have historically sailed. There are lakes and rivers in Africa. People there do swim. They just don’t produce any Michael Phelps. Oh yeah, I forgot Zimbabwe won a couple medals in swimming. Ummm, Kirsty Coventry is a white girl who swims for Auburn. By the racial equality argument, Zimbabwe shouldn’t need to import little blonde girls to swim for them. Africans ought to be able to swim as fast as whites. Yet, swimming is dominated by Europeans and East Asians. Pick your sport and there is generally ethnically determined favorites due to SMALL genetic differences. Sure, it sucks if your genes conspire against you being an elite swimmer or sprinter, but them’s the breaks.
