Surprise, there are actually more diverse sets of black people than &quot;African&quot;, each with their own biological diversity. African-Americans (that is, blacks in America who can trace their ancestors to the southern slaves) overwhelming come from a specific part of Africa, and those Africans are quite different from Africans elsewhere on the continent. You even have race wars among different ethnic groups of Africans! (See Rwanda for a particularly gruesome example.) So some African <i>subgroups</i> are actually better at different athletic traits -- not all can jump like African-Americans, but then again not all can sprint like another group, or run for very long distances like yet another group -- just as not all White people are actually as intelligent on average as the British. Human biological diversity is pretty rich and varied, it&#x27;s just unfortunate that the thing that matters most in modern society (intelligence) correlates as well as it does with such general and otherwise not very telling traits like skin color.
