Racial differences...

One example, and one known to be influenced by parental expectations; it isn't widely suggestive even. On the other hand, sickle-cell is almost exclusively an African condition, for obvious reasons, to the extent that the condition in a European usually indicates African ancestry.

So Environment is not "the" factor.

But PVC. One might as well say that people with African ancestry have darker skin. This is what we are talking about:

Is it then so far fetched to assume that the difference doesn't stop at the physical attributes, but that there also exist cognitive differences?

Right? It's about assuming cognitive differences. I think it is usual to assume no difference until one is shown.

Violent sports football boxing etc are dominated by the poor oftentimes and before blacks were so dominant at such sports it was the forte of port immigrant groups like the Irish in boxing.

These kids in the ghetto grow up thinking they have to be athletic and they have t go to the pros to get UT of the Hood. Plus they spend more time outdoors playing sports than rich kids all you need is a football or basketball.

Furthermore sports like swimming and hockey are so ridiculously white dominated because they are expensive
. Hockey requires ice tint and all that gear most poor kids can't afford it and swimming you need a good pool or a team of which there are very few in low income areas.

Racial differences become negligible in comparison to cultural and environmental factors.

Good book about this is outliers by Malcolm gladwell talks exactly about the hockey situation in Canada reenk spoke about
