Scientists in Kenya say it is a "game-changer" that challenges our understanding of the story of humankind.
They've discovered stone tools that are hundreds of thousands of years older than any others ever found.
They date back 3.3 million years and that indicates they were made by a species that preceded humans.
....
The textbook answer was that stone tools were first used by the genus homo - which includes us, homo sapien. There's very little probability that homo was around at 3.3 million, so this would suggest that an earlier human ancestor - probably Australopithecus, which includes the famous Lucy skeleton known from Ethiopia - is probably making and using some kind of stone tools.
