Palaeogenomics, the discipline that studies ancient genomes, has revolution- ized our understanding of past societies. Recent advances in this field allow us not only to trace migrations and interactions between populations but also to reconstruct entire aspects of prehistoric and ancient societies, including their kinship relations and general health. But what about the children, who have often left few tangible traces for traditional archaeological research? This conference aims to explore what the genomes of the youngest members of these communities reveal about their status, social roles, and the practices they were subjected to. Through concrete examples, we will discover how ancient DNA sheds new light on the place of children throughout time, from the Palaeolithic to Antiquity.
