[QUOTE="Umbran, post: 6515717, member: 177"] Heck, that sort of thing can come from sheer differences in diet and exercise patterns. Compare the phenotypic differences between a human who exercises daily and eats a healthy diet, and one who sits on a sofa eating Cheetos and drinking Moutnain Dew all day. Think if the behavior differences are from birth, through your entire development, and into adulthood. You'll have two markedly different individuals. Similarly - for the same genetic content in humans, you can end up with individuals of markedly different heights, depending on the protein content of their diet in their formative years. This isn't genetic polymorphism (which still needs some selective pressure to display itself clearly), it is the same genes under different conditions. Remember, in some species, whether an individual turns out male ore female can be based on the temperature the eggs were kept at during development. Life... can be kinda freaky :) [/QUOTE]
