4 . Macaques don’t use the sharp flakes they create for anything, Luncz adds, noting that the monkeys have sharp teeth and don’t need cutting tools. The similar ancient stone tools collected from some of the earliest known sites, however, show evidence of being used for cutting tasks. For example, in Oldowan, a site dating between 3.3 million and 1.5 million years ago, researchers analyzed use-wear patterns on the tools and found that some of the flakes showed damage along their edges, indicating that they had been used for cutting.
