Stone tools discovered 5000 years ago in the Pulur Mound excavation in Erzurum, where the speaker worked as an anthropologist, provide important clues to understanding the protein-based diets of prehistoric people and the effects of this diet on human anatomy. Similarly, her fieldwork in Ethiopia has revealed how communities still prepare food with stone tools today, continuing their prehistoric lifestyles. Through these two examples, the differences between the hunter-gatherer lifestyle and modern nutrition and reflections of these differences on humans will be discussed. In this context, it will be conveyed how research conducted at the ANAMED Library plays a critical role in understanding these historical and biological connections. The aim is to present the traces of our nutritional journey from the past to the present within a scientific and cultural framework.
