What do Capuchin monkeys use stones for?

Capuchin monkeys are known for their remarkable use of stones as tools, primarily for both digging and cracking nuts. This behavior exemplifies their cognitive abilities and problem-solving skills. When cracking nuts, Capuchins will select appropriate stones to serve as hammers, striking nuts against harder surfaces to access the nutritious contents inside. Additionally, they employ stones to dig into the ground to find tubers and other food sources buried beneath the surface. This dual usage of stones highlights the flexibility and ingenuity of Capuchin monkeys in their foraging strategies, showcasing their adaptability to varying food resources in their natural habitats. Their ability to use tools for different purposes also provides insights into the evolutionary development of tool use in primates.
