I do but also when I describe the environment in which we evolved I'm not talking about the last 10,000 years really, so not including mega civilizations like the Egyptians. I'm talking about the other 99% of our existence where you largely took food out of the ground and occasionally directly hunted wild animals. The idea is that your jaw/teeth expect chewing this kind of food and use that information to determine how your teeth should be correctly placed in your jaw as it is still growing. I don't have any specific references handy but I first read about the teeth thing in the excellent book: The Story of the Human Body: Evolution, Health, and Disease
