I did some research once trying to find out the differences between races of people and what I found out suprised me. It turns out there are huge differences the races. The different races of people have become rather specialized in the frequency of traits they possess. Humans can channel there energy into either physical or mental attributes or a combination ot the two.
Accusing me of being a racist is not going to work, my x-wife is black, from west africa(Ghana) and "race" was not a factor in our divorce. Just in case your wondering, african women are not bad, all the sex you want and they take care of the kids. As for myself, I'm white with blue eyes.
Africa is not a challenging place to survive in so people so it did not favor those in the population with a high IQ. This is not to suggest that intelligent people don't exist in africa, its just that the frequency of high IQ is not as common. I will mention my x wives father is a physician and her mother is a nurse, they are more intelligent that most white people I know. Since the geography and climate of africa did not generally favor people with high IQ, they developed more physically superior traits than other races.
People from west africa are the most physically gifted people in the world. They are famous for there athletic ability and feats of strength because of higher hormone levels in both men and women. The average testosterone level for west african men is 19% higher than for white men. Every record in the 100 and 200 M track events are held by people of west african descent. . My x wives brother had a track scholarship in college and could run like a cheetah.
People from east africa have the most physical endurance of any race in the world. There bodies produce an enzyme that actually increases there endurance. In ancient times the people could travel long distance were the ones that survived and this trait became very common in the population. Every record in long distance track events are held by people of east african descent.
Asian people evolved in a much more technically challenging enviroment that favored people with a high IQ. As a result they are the most intellectually gifted of all the human races. They consistently score the highest in IQ tests. There hormone levels are lower than other races of people, men have less body hair and women smaller breasts as a result.
The physiology of white, europeans is somewhere between asians and africans. You will find a lot variation in the intelligence and athletic ability of caucasians. With white skin and long noses we well adapted for cold weather.
Its important to remember what I have just told you is generalized information. It is potentially dangerous to generalize or attempt to define a race of people in any way. In any population there are those people that will not fit the racial profiles I have outlined. I hope I addressed this subject in a way thats both tasteful and helpful to all readers.
On rare occasion a genetic freak will result like Dolph Lundgren. Hes 6 5 , has an IQ of 160, speaks 4 languages, masters degree from MIT and has a black belt in Karate. Einsteins IQ was 160 also.
