Just look at the evidence. What contributions to science and technology has come from Africa or its descendants??? If inventing and science was an Olympic event??? But yet the black race is extolled for their athletic achievement. We all admit they are more athletic(obvious) which by the way is hard to take as a white man. I can understand it must be hard for a black person to admit lack of intelligence, you cant have it all. Not only different body structure but also brain. One more point, as black people have pointed out to me they were the original humans( or is it aborigines) that gives them more time to develop their continent, just compare it to Europe, where would you want to live???
