A dead man, found by hikers 25 years ago near the Austrian-Italian border, turns out to have died more than 5,000 years ago.

In the southwest of France, Neanderthals built one of the world’s oldest constructions—176,000-year-old semicircular walls of stalagmites in the bowels of a cave.

Researchers find evidence that one bit of Neanderthal DNA can boost the risk of tobacco addiction, while others can slightly raise or lower the risk of being diagnosed with depression.
