Ancient DNA solves the mystery of who made a set of stone tools

In this episode:


0:48 How hominins spread through Europe

Ancient stone tools are often uncovered in Europe, but it can be difficult to identify who crafted them, as Neanderthals and Homo sapiens coexisted in the region for several thousand years. The makers of one type of tool found in northern Europe has long puzzled researchers, but now through genetic analysis of nearby skeletal fragments, it has been revealed that they were made by Homo sapiens. The age of these tools suggests that modern humans were more widespread and adaptable to living in colder climates than previously thought.
