The animal known for its intelligence and use of tools is the chimpanzee (Pan troglodytes). Chimpanzees are members of the great ape family and are closely related to humans, sharing about 98% of their DNA. They demonstrate remarkable cognitive abilities, including problem-solving skills, communication, and social learning. Tool use is a significant aspect of their behavior; chimpanzees have been observed using sticks to extract termites from their nests, using stones to crack nuts, and even fashioning tools to assist with their foraging. Their complex social structures and ability to learn from one another make them one of the most intelligent species in the animal kingdom.
