[Yes it may be true that disease susceptibility may be higher in certain social/geographic groups but in those same groups you cannot find another trait with a statistically significant occurrence (e.g. height, skin color, metabolic rate, brain weight, etc...).
So what you are saying is that I couldn't find a group with a high occurence of a specific disease that existed in many geographic areas that did not have a high rate of occurence of other traits like skin color, bone density, hip geometry, bone structure, etc?
Yes, I am saying exactly that.
People of African ancestry have a high occurence of sickle cell, a high occurence of dark skin, a high occurrence of greater bone density in the females when compared to other "races" along with a different hip geometry, and a high occurrence of unique bone structure relative to other "races".
All of those traits are not unique to people of african ancestry (everyone on earth). People in India also have dark skin, etc...
I'm curious. Can you tell me why I am white?
Ummm...yes. Your ancestor's skin lightened to allow for better UV absorbtion.
but I would develop no other traits in the same manner?
