Long ago (therefore I have no citation and do this from long term memory) was a study that noted how muscle fiber varied depending upon the Africa that a person came from. (BTW when I explained this to some people, they though I was being racist.) Some regions had diets and environments that encouraged strong muscle structure (west Africa?) - American football linemen. Others regions encourage muscle development that was lighter and could create a more sudden burst of energy (east Africa?) - running and defensive backs. Then you have the unique characteristic of those from Ethiopia where great endurance was necessary to survive - distance runners.
The point was that muscle development varied in different parts of Africa because of regional diet and what the environment demanded of its residents. Nothing racist about this. Classic study of genetics.
In that same line of research - many Caucasians are closer, genetically, to Africans than to other Caucasians. We tend to associate race with features such a skin color. Actually skin color has very little relationship to one's race - genetically speaking.
If skin color determines a person's race, then so does height - another feature based upon genetics.
