Teeth are a vital component of vertebrate anatomy and a fundamental part of the fossil record. It was the evolution of teeth, associated with predation, that drove the evolution of the wide array of fish, amphibians, reptiles, and then mammals. Peter S. Ungar looks at how, without teeth, none of these developments could have occurred.
