Here's why:
* Diverse Tool Use: Chimps use a wide array of tools, including sticks to fish for termites, rocks to crack open nuts, leaves as sponges to soak up water, and even twigs to probe for honey.
* Problem Solving: They show remarkable problem-solving skills when using tools, adapting their techniques based on the situation.
* Learning and Teaching: Chimps learn tool use from their mothers and peers, demonstrating a cultural transmission of knowledge.
* Innovation: They've been observed inventing new tools for specific tasks, showing a level of ingenuity.
While other animals like crows, dolphins, and even some primates use tools, the complexity and variety of chimpanzee tool use sets them apart.
