Stones with cutting edges resembling tools, are not only apes, but other species of primates. It is found, archaeologists from Brazil and the UK, whose discovery changes the understanding of the evolution of human activity. Their findings the researchers presented in a paper published in the journal Nature.
Scientists have observed the behavior of the black-striped Capuchin (Sapajus libidinosus) in Brazil. It turned out that the monkeys are breaking down the rocks, resulting in formation of flakes with sharp edges. While these “tools” are not used in animals, although very similar to those found in the areas of alleged sites of ancient people.
Other studies have demonstrated that chimpanzees deliberately create the stones with cutting edges. Now, however, it is shown that this is not unique to the group hominini (Hominini), where, in addition to chimpanzees, include human and gorilla. If it is still not clear why the Capuchins split the stones.
According to researchers, to confirm what was found by paleontologists stones are used as tools, further evidence is needed, for example, processed animal bones.
