Complex tools discovered from 350,000 years earlier than expected

In “Stone tools shed light on early human migrations” (Nature, August 31, 2011), Matt Kaplan tells us that “Hominins with different tool-making technologies coexisted,”

The axes, found in Kenya by Christopher Lepre, a palaeontologist at Columbia University in New York, and his team are estimated to be around 1.76 million years old. That’s 350,000 years older than any other complex tools yet discovered.

e significant finding is that the hand axes from 1.5 million years ago were found beside primitive chopping tools of a type used a million years earlieDid one type of human make both types of tools? Stone toolmaking is hard work, and it may be that no one saw a need to embellish a device that worked fine as it was for chopping meat or vegetables.
