Developmental biology: Teeth in double trouble
Georgy Koentges1
Abstract
Almost all vertebrates have teeth of some sort. But where, in developmental terms, do teeth come from? Results drawn from experimental embryology provide an illuminating perspective on this contentious question.
Teeth are made of some of the hardest stuff in organic nature, and many fossil vertebrates are known only from their dental remains. So teeth are central for systematic classification and reconstruction of animal life-histories, not to mention forensic science, horror movies and musicals.
