Dude there isn't much "jungle' in Africa, jungle is usually defined as thick tropical vegetation, must of Africa is either desert (Sahara, Kalahari) or wide-open grasslands usually known as 'bush country'. There are large jungles in Central Africa (Zaire, Uganda), where gorillas live and where the King Kong story is set, which has lead many people to think that this is typical of all of the continent, but it isn't true. Anyway most american 'blacks' are of West African descent and their ancestors aren't from any jungles. blacks of West African descent are faster at sprint distances (less than 400m) than other groups, that is why they currently dominate the NFL at running back, WR and CB positions, but speed over short distances is only one type of athletic ability. Many people think that events like the Triathalon or decathalon are a better measure of overall athletic ability and blacks definitely don't dominate at those events.
