Human Evolution and Diet

This specific anthropological research identifies the functions of teeth by closely examining their surface damage characteristics. We have observed the dental micro wear striation on a variety of populations, that range from being almost carnivorous to largely vegetarian, to improve our knowledge of early human diets. The method interprets the food movements in mouth by the form of striae present on the buccal enamel of the back teeth. The comparative examination on a large quantity of human remains, from the European Pleistocene to modern hunter-gatherers, show variability that can be explained eco-geographically as well as culturally, allowing the reconstruction of a grid or an atlas of major eating patterns reflecting different dietary traditions worldwide.
