What teeth can teach us about the evolution of the human speciesWhether we realize it or not, we carry in our mouths the legacy of our evolution. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. In Evolution's Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution and climate change with new approaches to uncovering dietary clues from fossil teeth to present a remarkable investigation into the ways that teeth—their shape, chemistry, and wear—reveal how we came to be.Ungar describes how a tooth's'foodprints'—distinctive patterns of microscopic wear and tear—provide telltale details about what an animal actually ate in the past. These clues, combined with groundbreaking research in paleoclimatology, demonstrate how a changing climate altered the food options available to our ancestors, what Ungar calls the biospheric buffet. When diets change, species change, and Ungar traces how diet and an unpredictable climate determined who among our ancestors was winnowed out and who survived, as well as why we transitioned from the role of forager to farmer. By sifting through the evidence—and the scars on our teeth—Ungar makes the important case for what might or might not be the most natural diet for humans.Traveling the four corners of the globe and combining scientific breakthroughs with vivid narrative, Evolution's Bite presents a unique dental perspective on our astonishing human development.

Researchers have long had an interest in dental morphology as a genetic proxy to reconstruct population history. Much interest was fostered by the use of standard plaques and associated descriptions that comprise the Arizona State University Dental Anthropology System, developed by Christy G. Turner, II and students. This system has served as the foundation for hundreds of anthropological studies for over 30 years. In recognition of that success, this volume brings together some of the world's leading dental morphologists to expand upon the concepts and methods presented in the popular The Anthropology of Modern Human Teeth (Cambridge, 1997), leading the reader from method to applied research. After a preparatory section on the current knowledge of heritability and gene expression, a series of case studies demonstrate the utility of dental morphological study in both fossil and more recent populations (and individuals), from local to global scales.

Bringing together a variety of accomplished dental researchers, this book covers a range of topics germane to the study of human and other primate teeth. The chapters encompass work on individuals to samples, ranging from prehistoric to modern times. The focus throughout the book is the methodology required for the study of modern dental anthropology, comprising the scientific methods in use today - ranging from simple observation to advanced computer-based analyses - which can be utilized by the reader in their own dental research. Originating from the 20th anniversary meeting of the Dental Anthropology Association, this is a valuable reference source for graduate students, academic researchers and professionals in the social and life sciences, as well as clinicians.

We are interested in the evolution of hominin diets for several reasons. One is the fundamental concern over our present-day eating habits and the consequences of our societal choices, such as obesity prevalent in some cultures and starvation in others. Another is that humans have learned to feed themselves in extremely varied environments, and these adaptations, which are fundamentally different from those of our closest biological relatives, have to have had historical roots of varying depth. The third, and the reason why most paleoanthropologists are interested in this question, is that a species'trophic level and feeding adaptations can have a strong effect on body size, locomotion,'life history strategies', geographic range, habitat choice, and social behavior. Diet is key to understanding the ecology and evolution of our distant ancestors and their kin, the early hominins. A study of the range of foods eaten by our progenitors underscores just how unhealthy many of our diets are today. This volume brings together authorities from disparate fields to offer new insights into the diets of our ancestors. Paleontologists, archaeologists, primatologists, nutritionists and other researchers all contribute pieces to the puzzle. This volume has at its core four main sections: · Reconstructed diets based on hominin fossils--tooth size, shape, structure, wear, and chemistry, mandibular biomechanics · Archaeological evidence of subsistence--stone tools and modified bones · Models of early hominin diets based on the diets of living primates--both human and non-human, paleoecology, and energetics · Nutritional analyses and their implications for evolutionary medicine New techniques for gleaning information from fossil teeth, bones, and stone tools, new theories stemming from studies of paleoecology, and new models coming from analogy with modern humans and other primates all contribute to our understanding. When these approaches are brought together, they offer an impressive glimpse into the lives of our distant ancestors. The contributions in this volume explore the frontiers of our knowledge in each of these disciplines as they address the knowns, the unknowns, and the unknowables of the evolution of hominin diets.
