I can explain to you why Kenyans are great runners. It is because of their disposition of running, which would support my theory that handpicking people would make them prone to accel in their chosen area of expertise. Now there is no correlation between evolution and martial arts. There is a connection of an entity proclaiming an expertise to something they practice and has been taught in their culture. Of course Asians dominate the martial arts!! That’s where it originated. I wouldn’t credit evolution for their success in it. Just like I wouldn’t praise evolution for Canadians being good at hockey. That is just what they do in that country.
Regardless, what you said about Kenyan runners proves my point exactly. Kenyan runners generally do not look like African Americans. If whites had handpicked runners, then they would have picked them, but they didn’t. They wanted strong workers, which would explain the average size of an African American compared to a black African. Your ratios about the NBA prove my point exactly. Despite the ratio of blacks to whites not being in the black’s favor, they still dominate the league due to their frames and physical make up which can be attributed to the handpicked selection. The greatest athletes do indeed participate in professional sports, and they consist of African Americans, not black Africans. If you are saying that handpicking the Africans to bring to America is not the reason they are successful in professional sports, then why does football, a size and strength intensive sport have predominately African Americans, and not Africans.
