The reason blacks are under represented in science academia etc is that they don't have the cognitive architecture to enable them to engage in high level scientific enquiry. Its an easily measureable and empirical fact. For example negroids have a much smaller cranial capacity than whites and consequently much less 'grey matter'. If you imagine the black brain as a family PC, blacks just don't have the hardware to meet the minimum system requirements of complex analytical and conceptual scientific tasks. Its the same reason there aren't many black chess grandmasters (if there are any at all). Blacks do poorly in all scholastic or academic activities and always have done. Just compare Africa to other continents and a pattern emerges. Prior to the colonosation of Africa the blacks hadn't even managed to build a library, a museum, concert hall, hospital, aquaduct or palace. They didn't even have a merchant navy, proper roads, newspapers, or electricity amoung a million other things the whites gave them. Anatomy is Destiny. The fact that they were eating each other at the time doesnt help either
