Chimpanzees are known for their ability to use tools, a behavior that was once thought to be uniquely human. They use sticks to fish for termites, stones to crack nuts, and leaves as sponges or spoons. This ability to use tools demonstrates the problem-solving skills of chimpanzees and their capacity for learning and innovation.
