You are right of course. Climate and terrain do cause changes. Templetons research goes to a much deeper level.bottleneck said:I always assumed that physical differences between people of different countries - like eskimos and aboriginees for example.. was down to human evolution - evolving to the conditions.
Templeton goes on to say, "There is more genetic similarity between Europeans and sub-Saharan Africans and between Europeans and Melanesians, inhabitants of islands northeast of Australia, than there is between Africans and Melanesians. Yet, sub-Saharan Africans and Melanesians share dark skin, hair texture and cranial-facial features, traits commonly used to classify people into races."
According to Templeton, this example shows that 'racial traits' are grossly incompatible with overall genetic differences between human populations."
