A tooth is not simply a tooth, as zoologist Bill Schutt writes in his new book, Bite: An Incisive History of Teeth, from Hagfish to Humans. Teeth first showed up among vertebrates some 500 million years ago, and ever since, they’ve had much to do with the survival of many species. There are teeth that sharpen themselves with every snap (as with dogs and wolves), teeth that grow forever (as the poor babirusa knows all too well), and teeth that grow in a conveyer belt (ask a crocodile, but don’t get too close). The shape and appearance of teeth can tell us a lot about how animals evolved—and in the case of humans, where we stand on the social ladder. And there’s much more still to be learned, both about past life on this planet and future innovations in dentistry. Bill Schutt, a vertebrate zoologist and retired biology preofssor, is a research associate at the American Museum of Natural history, and he joins us today from New York.  Go beyond the episode: Bill Schutt’s Bite: An Incisive History of Teeth, from Hagfish to HumansVisit our episode page to see some of Patricia J.
