Brain scans of modern listeners suggest that Aztec whistles sound like human screams, which may have prepared sacrifice victims for their journey to the underworld.

Fifty years after a fossil skeleton of Australopithecus afarensis was unearthed in Ethiopia, we know so much more about how this iconic species lived and died.

Lucy lived in a wide range of habitats from northern Ethiopia to northern Kenya. Researchers now believe she wasn't the only australopithecine species there.
