Brazilian monkeys found creating stone tools

Creation of primitive stone tools has long been attributed to the early humans’ intelligence but that may change soon as a species of Brazilian monkeys has recently been found creating similar stone tools.

A team of researchers led by Tomos Proffitt of Oxford University said they were surprised when they saw bearded capuchin monkeys (Sapajus libidinosus) in a Brazilian forest creating stone tools.

The wild beasts were creating stone flakes, a sort of primitive tool that could be used as a blunt knife, by hitting one rock with another in a certain manner to break flakes.

While it couldn’t be ascertained if the monkeys were knowingly making those stone tools, it has become clear that they can also make such tools. The researchers admitted that they would now have to be more cautious whenever they come across ancient sites of early humans where similar tools are often found.

Michael Haslam, a co-author of the study, said, “The fact that we have discovered monkeys can produce the same result does throw a bit of a spanner in the works in our thinking on evolutionary behaviour and how we attribute such artefacts.”

The surprising discovery of the creation of stone tools by Brazilian moneys was detailed in a recent edition of the widely-acclaimed journal Nature.
