4. Capuchin Monkeys
Capuchin monkeys are renowned for their dexterity and sophisticated tool use. They employ stones as hammers and anvils to crack open nuts, a process that requires precision and practice. This behavior has been observed for thousands of years, with evidence indicating that capuchins have been using stone tools for around 3,000 years. (ucl.ac.uk) Their ability to select appropriate tools and modulate force based on the condition of the nut demonstrates a level of problem-solving and foresight that challenges traditional views of primate intelligence.
