The skeleton of a young adult found in a cave in Indonesia that is missing its left foot and part of its left leg reveal the oldest known evidence of an amputation, according to a new study.
The discovery suggests an earlier start to the Middle Stone Age in Africa than previously documented. It also offers clues to early social networks and symbolic art by human ancestors.
Scientists have found stone tools in India dating back to 385,000 years ago. The sharp tools were made with a Stone Age technique thought to have originated in Africa and Europe.
