Straight-tusked elephants (Palaeoloxodon antiquus) were the largest terrestrial mammals of the Pleistocene epoch, present in Europe and western Asia between 800,000 and 100,000 years ago. A new analysis of 125,000-year-old bones of straight-tusked elephants from ancient lake deposits in Germany shows that hunting of these enormous animals was part of the cultural repertoire of Neanderthals there, over 2,000 years, many dozens of generations.

This map illustrates the geography of Beringia, the land bridge that formed between North America and Asia during the last glaciation. Humans crossed Beringia from Asia to North America during the glacial period depicted on this map. Lakes and drainages have been reconstructed to provide a better perspective on the environment of the land mass according to bathymetric data having a grid spacing of 1 km (100 m for Norton Sound). Some of the lake basins are shallow and may have been wetlands rather than open water bodies. Image credit: J.D. Bond / Yukon Geological Survey / Government of Yukon.
