Homo neanderthalensis emerged in Eurasia between 350,000 and 600,000 years ago as the earliest body of European people, that left behind a substantial tradition, a set of evaluable historic data through rich fossil record in Europe's limestone caves and a patchwork of occupation sites over large areas, including Mousterian cultural assemblages.
