Tool use refers to the ability of an organism to manipulate objects in the environment to achieve a specific goal. This behavior is commonly observed in various species, including humans, primates, birds, and even some insects. Tools can range from simple items like sticks and stones to complex devices designed for specific tasks. The development of tool use is significant in the study of animal behavior and cognition. It demonstrates problem-solving skills and adaptability, allowing species to access food, build shelters, or defend themselves. Understanding tool use helps researchers learn more about the evolution of intelligence and the capabilities of different organisms.
