The tales teeth tell

"Why do anthropologists study teeth? Teeth contain detailed records of growth health and diet as well as our evolutionary history. So what are the tales teeth tell? The French naturalist George Cuvier famously remarked "Show me your teeth and I will tell you who you are." In this book we will explore the intimate precision striking beauty and integrative power of incremental growth rhythms in teeth. We will also consider the surprising records of behavior that remain on their surfaces for millennia. For example the plaque our hygienists carefully remove traps food particles bacteria and DNA from our own cells in a sticky layer that can fossilize over time into dental calculus. While calculus doesn't show the same faithful records as enamel and dentine it captures human activity after our teeth finish growing continuing the story of our behavior and health into adulthood and old age. We'll learn how complementary clues such as microscopic scratches and pits formed during chewing have spawned serious debates about the evolution of the human diet. And we'll see how evidence from teeth may point to the uniqueness of our own species Homo sapiens with our long childhoods remarkably diverse diets and complex behaviors"--
