In genetics, it’s not just the living who advance the field: DNA preserved in the brittle bones of our ancestors can provide significant insight into our genetic history. Such is the case with a new genetic history of Europe, traced by an international team of researchers and published today in Science. By creating a seamless genetic map from 7,500 to 3,500 years ago in one geographic region, scientists discovered that the genetic diversity of modern day Europe can’t be explained by a single migration, as previously thought, but by multiple migrations coming from a range of areas in modern day...
