Our prehistoric human ancestors relied on deliberately modified and sharpened stone tools as early as 3.3 million years ago. This persistence suggests that these early humans had developed a successful survival strategy that worked across a wide range of ecological settings. Nearby outcrops offered a variety of raw materials, but early humans selected the most suitable types of rock for their needs. Understanding the functional importance of these stone tools from this site is crucial to evaluating their evolutionary significance. One clue comes from a fossilised animal bone found at the site, bearing cut marks made by sharp-edged stone tools.
