There are something biological difference between the different classes of people such as negroes, mongoloid etc etc. Now tell me one thing, among human being, which class is the most biologically developed?
“Which is most biologically developed”. How would you even begin to define this when there is so much variation within each family let alone each country? This is the type of thing Hitler was interested in. It lead to a widepread Eugenics movement which is now known as the holocaust. Don’t even go there. I think you are getting confused between anthropology and genealogy because “classes” or “races” are contexts which are as synthetic and unnatural and man-made as cheese in a can. If you are genuinely interested between how genetics really does not follow culturally perceived classes of “race” which are purely cultural, and not biological you could start with studying the movement of the different blood types throughout the world and the patterns of migration over the 1000s of years. http://www.bloodbook.com/world-abo.html This is another good website which begins to unravel the complexities of our genetic ancestry within the human species.
