I know there are two other threads on teeth, but not one on the shape of teeth.
Why is it that humans, especially white people, don’t have perfect teeth like most of all the other mammals? What I mean by perfect teeth is that they arn’t aligned perfectly. It is because of our diets, or is it genetic? I know that when I went to Samoa, all of the natives had perfectly aligned teeth. Also, many African Americans have perfect teeth as well. Is it because of sucking your thumb as a baby? If anyone had any information I would appreciate it a lot.
