Some of Europe’s earliest inhabitants mysteriously vanished toward the end of the last ice age and were largely replaced by others, a new genetic analysis finds. The finds come from an analysis of dozens of ancient fossil remains collected across Europe. The genetic turnover was likely the result of a rapidly changing climate, which the earlier inhabitants of Europe couldn’t adapt to quickly enough, said the study’s co-author, Cosimo Posth, an archaeogenetics doctoral candidate at the University of Tübingen in Germany.
