Three new papers published in Science, a multi-year research collaboration by the David Reich Institute, Max Planck and several other universities, have helped to bring the murky forces of prehistoric migration into much finer focus. The first focuses on the origins of the Proto-Indo-European and Proto-Indo-Anatolian languages through new genetic data, and the last focuses on the ethnic diversity of cities around the Roman empire and in early medieval Europe, which might be the subject of a future blog post or two.
