Ungar / 2017 / English / PDF. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. Comparative anatomy is a fairly coarse approach, which despite convergences allows only the most specialized diets to be ruled out. Although such comparisons do not provide direct evidence of hominin diets, they do suggest potentially useful research strategies. 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. This item is available to borrow from 2 library branches. Old tools and bones can reveal a lot about our ancestors. Diet is key to understanding the past, present, and future of our species.

But other species tend not to have such afflictions, nor did our fossil forebears. Among these categories, there are differences in dentition, a result of primate dietary plasticity. Journal of Human Evolution. [Article in Italian] Pellicciotta E. The dental pattern allows a taxonomic assignment of a primate and some deductions about his food preference and survival behaviour. Diet has shaped human jaw bones; a result that could help explain why many people suffer with overcrowded teeth. Shop Evolution's Bite - A Story of Teeth - Diet - and Human Origins by Pete. Comparative anatomy is a fairly coarse approach, which despite converge … Throughout human evolution we became more and more equipped to eat meat and less and less equipped to eat plants. New technique for studying tooth enamel – implications for diet and tooth shape during human evolution. The purpose is to define the Hominid's diet and behaviour, through a dental study. On the other hand, recent changes in the types of foods we eat may lie at the root of many of the health problems we face today.
