Some stone tools have been found in Kenya that are 3.3 million years old. The earliest humans came 700,000 years after these tools were made. So, who could have made them?


Scientists now believe that earlier ancestors of humans were more intelligent than we believed. The species Australopithecus afarensis, which has both ape and human features (picture above) could possibly have made the tools.

Scientists used to believe that this species was quite primitive, but after the discovery of the tools, they now believe that it is possible that this species was more sophisticated and used tools to hunt.


This has been described as the “most important archaeological discovery of the past 50 years”
