Stone tools produced by monkeys 50,000 years ago were found in Brazil
Additionally, according to the experts, "we are certain that the early archeological sites from Brazil may not be human-derived but may belong to capuchin monkeys."
According to a study1 that was first published in November, stone tools that are thought to be around 50,000 years old were discovered in Pedra Furada in northern Brazil and that these tools were produced by monkeys who lived at that time. The Holocene journal published the peer-reviewed paper. According to the report, the tools discovered at the sites are distinguished "by the utilization of instantly available raw material."
Capucin monkeys are typically found in the tropical jungles of Central and South America. They are regarded as the most intelligent New World monkey. Thousands of years ago, the Pedra Furada was home to hundreds of archaeological sites. Researchers in the study compared stone tools from the Pedra Furada to deposits of contemporary capuchin stone tools and found that the Pedra Furada tools are congruent with the capuchin stone tools. Additionally, according to the experts, "we are certain that the early archeological sites from Brazil may not be human-derived but may belong to capuchin monkeys."
