[QUOTE="tansy, post: 70854410, member: 210572"] I'm trying to understand how these things work...it only may be relevant in that if there is gradual change in people according to their environment, eventually certain traits may be completely eliminated? As long as there is a particular gene still lingering about so to speak (is it recessive genes I'm thinking about, rather than dominant?), could that rematerialise even thousands of years after it was more common? Supposing for example, half the people in a particular population had blond hair and half had black hair, but for some reason for decades or centuries or millennia, no-one was born with black hair...would it be possible for someone to suddenly be born with black hair, and everyone would be completely taken by surprise? Could that gene remain dormant, so to speak, for that long? Sorry, not explaining my question well, but am trying to understand the relationship between what is inherently present in genetic material and what might actually gradually change (mutate?) or be lost, but without other human contact from another population, so that certain traits would become more or less 'fixed'..the new 'normal' if you like.
