Over millions of years in the fossil record, hominin teeth preserve a high-fidelity record of their own growth, development, wear, chemistry and pathology. They yield insights into human evolution that are difficult, if not impossible, to achieve through other sources of fossil or archaeological data. Integrating dental findings with current debates and issues in palaeoanthropology, this book shows how fossil hominin teeth shed light on the origins and evolution of our dietary diversity, extended childhoods, long lifespans, and other fundamental features of human biology. It assesses methods to interpret different lines of dental evidence, providing a critical, practical approach that will appeal to students and researchers in biological anthropology and related fields such as dental science, oral biology, evolutionary biology, and palaeontology.
