You may well consider them for granted, but your tooth are a marvel. They crack up all your food over the study course of your lifetime, although remaining strong enough to stand up to breakage by themselves. How do they do it? Peter S. Ungar traces the evolution of mammalian molars from primitive cone-like constructions to the myriad varieties of today’s species, from lions to cows to men and women.
