Neanderthals may have died off because they failed to harness the power of fire to the extent their human cousins did, a new data analysis from Boston University suggests.
Using fire for cooking would have allowed these human relatives to get more calories from the same amount of food, thereby edging out the Neanderthal population. Over time, the anatomically modern human population would have risen, while the Neanderthal population plummeted toward extinction, according to the model.
