Do you think genes play no part in IQ? I'd say East Africans are the best at long distance running. Of course, Ethiopian and Kenyans have national and international records and they come from historical environments where endurance was necessary to travel over long plains and hunt fast animals. Some tribes still exist like the Masai tribe.
Correct me if I'm wrong.
Good point. All the champions of heavyweight boxing or ATGS are majority African American or African e.g. Muhammad Ali, Sonny Liston, Larry Holmes, Joe Louis.
Rocky Marciano and Jack Dempsey are a part of the FEW heavyweight boxing champions who were great and WHITE.
Other champions include Marvin Hagler, Riddick Bowe, Evander Holyfield, Lennox Lewis, Tommy Hearn, etc - African Americans.
I think African Americans make up the majority in the NFL, and obviously they make up the majority in the NBA.
So I believe African Americans are more athletic and successful in these dominant sports than other races IN America.
It makes sense to ME that Africans in Africa as a whole have lower IQ than other races because they didn't need to be High-IQ in their daily nomadic lives. The West has a part to play since I know they've probably killed good African leaders or smart folk. They've assassinated a lot of smart engineers and etc from Morocco and the MENA.
But blaming environment and culture in today's age isn't feasible. You can do bad in school because you're lazy or didn't study and you can still have High-IQ, I'm sure.
