Genetic Profiles Change Through Time

A conversation with Hannah Moots (Center for Palaeogenetics, Stockholm) about paleogenetic research, its goals, methods, and conclusions. What does it mean to study ancient DNA, and what does it tell us about human history? The conversation is based on an article co-authored by Hannah and many other collaborators entitled "Ancient Rome: A Genetic Crossroads of Europe and the Mediterranean," Science 366 (2019) 708-714.
