Biochemical analysis of human remains has become a key feature in our understanding of past peoples. Ancient DNA and stable isotope analysis are now considered primary sources of information in the study of the geographic mobility of populations, their genetic affinities, and their diets.
The study of the human diet in Palaeolithic times is currently among the research areas generating the greatest advances in knowledge. Analysis of the Palaeolithic diet is conducted mainly on the basis of stable isotopes of carbon and nitrogen, which are present in the collagen of human bones. These isotopes indicate the types of food consumed by the individual in the years leading up to their death. Read more.
