African-Americans, who earlier in the century were segregated into black leagues, have in less than 50 years become the dominant racial group in basketball and football, despite the fact that they only make up 12.6% of the US population (U.S. Census Bureau, 1998). Today black players constitute 77% of the NBA, 64% of the WNBA, 65% of the NFL, and 15% of MLB
Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats
blacks and whites, when matched for SES variables, are virtually identical in average height, however, their physique and body proportions are much different. Blacks have shorter torsos, broader shoulders, smaller ribcages, narrower hips, and longer limbs (with comparative elongation of the distal segments). Fit samples of blacks and whites appear to be about the same weight on average (or perhaps blacks are marginally heavier), but fit blacks have on average less body fat, particularly on their limbs. It follows that blacks have a greater fat free body mass (i.e., bone, muscle and viscera) than whites. The smaller ribcage and narrower pelvis would indicate less viscera weight and indeed, blacks have been found to have substantially more total body musculature and denser, heavier bones than whites. This greater musculature is also distributed differently. Blacks show considerably more musculature in their glutes and thighs than whites, which gives a substantial advantage in locomotion. Blacks have also been shown to have on average greater cross sectional thickness in their limb musculature than whites, with the difference much greater in the proximal than distal limb segments. Naturally higher average testosterone levels and a greater number of testosterone receptors probably contribute to the leaner more heavily muscled physique of blacks compared to whites.
The African American was forced to adapt to manual labor for extensive periods of time. Thus, the large nose with wide nostrels able to intake oxygen at a higher rate to fuel the muscles.

I also believe that is due to evolution. For instance, why is it that marathon, and runing events are often won by someone for kenya? Because their ancestors did not have cars, or trains to ride. They ran. literally, long distances to get from one place to another.

I remember a theory from an anthropology class a number of years ago, that said black Americans aren't as smart as Africans. The theory went that the less intelligent ones were caught by the black slave traders, while the smart ones were able to escape or avoid capture.

This theory is not so new. Jimmy the Greek, the football handicapper that worked for CBS was fired for a very similar stated belief 30 years ago or so.

Evolution. Right. And that takes place over just a couple generations? None of our ancestors had cars.
Before people cite evolution as causative, they should learn a bit about it.
