Researchers re-excavated Bacho Kiro cave in Bulgaria and found bits of bone from modern humans as well as tools and jewelry.
By Ann GibbonsDuring a warm spell about 46,000 years ago, a small band of people took shelter in a cave on the northern slope of the Balkan Mountains in what is now Bulgaria.
There, they butchered bison, wild horses, and cave bears, leaving the cave floor littered with bones and a wealth of artifacts—ivory beads, pendants made with cave bear teeth, and stone blades stained with red ochre.This region had long been home to Neanderthals, who left stone tools in the same cave more than 50,000 years ago.
