Physical appearance, personality traits and natural selection in Europeans

Steve Sailer:

Greg Cochran's theory is that just as selecting for new personality traits in wild animals that you are trying to domesticate often introduces new physical looks, the famous diversity of looks among Europeans (red and blond hair, blue, gray, and green eyes) are by-products of natural selection for new personality traits favorable to survival in Europe. Blue eyes, for example, might possibly be a by-product of selection for something like shyness.
