Fire Used to Make Tools Earlier Than Previously Thought

fireFindings recently published in Science suggest that humans started using fire to help shape tools approximately 50,000 years earlier than previously thought.  Scientists had thought that fire was used to shape tools starting 25,000 years ago, but a 72,000-year-old cache of stone weapons found in Africa points to a much earlier start.  The lead researcher of the study, Kyle Brown an archaeologist at the University of Cape Town in South Africa, suggests that this use of fire potentially marks the turning point when Homo sapiens became “uniquely human.”  For more on the study, see National Geographic News.
