A Viable Scientific Explanation for why Africans Dominate Sports

September 10, 2015

Thomas Jefferson declared that “…all men were created equal…” Everybody knows this statement isn’t literally true.  When I was a little guy in grade school I wanted to become an NFL star.  Then I ran track in the 7th grade and much to my disappointment discovered there were many faster runners than me.  I knew I was too small and slow to ever make it as a professional football player.  Later in life, I wished I was 3 inches taller because I learned the chicks dig taller men.  Alas, I realized in some respects I was even less than average.

Thomas Jefferson didn’t actually mean all men were created equal, but he did believe all men should be treated equally under the law.  The subject of this blog entry is a touchy topic, so I want to make it clear that I agree with  the true meaning of Jefferson’s declaration, and I don’t believe in discriminating against people of varying races or religions.  I do not believe any race is superior to any other, though there are clear physical differences between races.  My essay is based on scientific facts published in peer-reviewed literature.  A scientific fact can not be considered racist or bigoted.

Athletes of African descent dominate running and jumping events in track, basketball, and certain positions in football such as running back, wide receiver, and defensive back.  There is not a single white cornerback in the NFL and only a handful of white running backs. This disparity can’t be explained by socio-economic factors alone.  While it is true that the average African-American family is economically poorer than the average white family, the total population of poor white people in America far outnumbers the total population of poor black people.  The pool of potential white participants who would like to escape poverty by playing basketball in the NBA or cornerback in the NFL is large but there are very few able to compete at that level due to a lack of natural ability.  There is an interesting and viable scientific explanation for this disparity.

Africa is the original birthplace of the human race.  Genetic studies show the original home of all species includes a more genetically diverse population.  After a new species evolves, they colonize new regions.  The populations that colonize new regions descend from the smaller gene pool that invaded the new territory. The history of Homo sapiens is an especially excellent illustration of this concept.  The ancestors of all Homo sapiens currently living on earth originally evolved in south Africa about 200,000 years ago.  About 60,000 years ago, a small population of humans left Africa and eventually the ancestors of this group spread throughout the world.  The entire population of Europeans, Asians, and Australian aborigines descend from just 1 or a few tribes that left Africa long ago.  This means Africans are more genetically diverse than the people who colonized the rest of world.  There is more genetic diversity in an African village of 70 people than there is in all of China.

The Khomani bush people of south Africa are the oldest race known.  Scientific studies show they are genetically the most diverse people in the world.  All of humanity descends from their ancestors.  Photos of Khomanis are remarkable.  Of course, they all have dark skin, but their facial features show a wide variation.  Some look Caucasian, some look Asian, and some have Negro features.

Khomani African Bushmen are genetically the oldest human race.  Their ancestors are the ancestors of tribes that gave birth to other Africans, Caucasians, and Asians.  Facial features within this tribe vary–some look Asian, others Negroid, and some resemble Caucasian.  Note the woman on the left.  She looks Asian, while the baby has Negroid features.

These Khomani children could almost pass for white.

As the descendants of the Khomani colonized the rest of Africa, the various tribes became geographically isolated.  Humans evolved in Africa for 140,000 years before any left the continent, so the overall population on this continent remained genetically more diverse than the human populations in the rest of the world.  This genetic diversity meant extremes in various body types were more pronounced in Africa than in Europe and Asia.  For example 7 foot tall Watusi tribesmen lived within miles of 4 foot tall pygmies.  Studies show that people who lived in west Africa evolved (on average) an higher ratio of fast twitch muscle fibers than any other population of people.  This made them extraordinary sprinters and jumpers.  This explains why all cornerbacks in the NFL  and most Olympic sprinters are of west African descent.   Studies show that people living in east Africa evolved the ability to produce more energy producing enzymes.  This helps with long distance running and explains why Kenyans are dominating marathon running.

Pygmy tribes live just a few miles from the very tall Watusis, demonstrating the amount of genetic diversity in Africa.  You won’t find any pygmies in the NFL or NBA.  Almost all African-Americans in those sports leagues are of west African descent located to the northwest of pygmy tribal areas.

The average human of West African descent has an higher ratio of fast twitch muscle fibers than other humans.  This explains why people of West African descent dominate sprinting, basketball, and certain positions in football such as running back, receiver, and defensive back.

Studies have also found that the average African has a greater bone density than the average white person.  This durability aids in contact sports.  Africans have a much lower rate of developing osteoporosis and hip fractures.  African women are less than half as likely to suffer hip fractures when they get older than white women.  They are even less likely to get hip fractures than white men.  However, this greater bone density is a disadvantage in competitive swimming.

Note: None of these minor physiological differences are related to intelligence in anyway.
