Brazilian scientists unearthed some 50,000-year-old stone tools and were shocked to realize they were not made by any species of the human world, but by a completely different creature.
In a paper published in the scientific journal The Hologen, a team of authors led by researchers Agustín M. Agnolín and Federico L. Agnolín from the National Institute of Anthropology and Thought Latin America (Argentina) and the Museum of Science Naturalist Argeintina said the remarkable tools mentioned above may have been created by the ancestors of today’s capuchin monkeys.
It is a collection of ancient stone tools made of pebbles and quartz, found at more than 800 archaeological sites in northeastern Brazil. The oldest tools are dated to 50,000 years old.
According to Science Alert, they naturally classify them as man-made stone tools.
In 2016, however, they discovered some surprising details when reviewing observational studies of today’s Brazilian capuchin monkey populations: They still often use small stones as hammers and large, flat stones as hammers. anvil to smash hard nuts.
These tools are carefully and deliberately “manufactured”, with cracks similar to how prehistoric people made stone tools.
More shocking, they… identical to what they believe to be Stone Age tools 50,000 years ago were unearthed.
As a result, the researchers were forced to admit the unbelievable fact that the stone tools they found in northeastern Brazil, including Pedra Fudara and several nearby sites, were the product of capuchin monkeys 50,000 years ago.
Capuchin monkeys, also known as capuchin monkeys, currently distributed in the tropical forests of Central America and South America, have a lifespan of regarding 15-25 years, with the name derived from the coat like a monk wearing a robe. hooded cape.
