Ancient human relative used fire, surprising discoveries suggest
Story by Mark Johnson
Explorers wriggling through cramped, pitch-black caves in South Africa claim to have discovered evidence that a human relative with a brain only one-third the size of ours used fire for light and cooking a few hundred thousand years ago. The unpublished findings — which add new wrinkles to the story of human evolution — have been met with both excitement and skepticism.
South African paleoanthropologist and National Geographic explorer Lee Berger described finding soot-covered walls, fragments of charcoal, burned antelope bones and rocks arranged as hearths in the Rising Star cave system, where nine years earlier the team uncovered the bones of a new member of the human family, Homo naledi.
Control of fire is considered a crucial milestone in human evolution, providing light to navigate dark places, enabling activity at night and leading to the cooking of food, and a subsequent increase in body mass. When exactly the breakthrough occurred, however, has been one of the most contested questions in all of paleoanthropology.
