> Crows are one of the only other animals that can make and use tools "Goodall observed other chimpanzees picking up leafy twigs, stripping off the leaves and using the stems to fish for insects. This change of a leafy twig into a tool was a major discovery. Prior to this, scientists thought that only humans manufactured and used tools, and that this ability was what separated humans from other animals.[19] In 1990, it was claimed the only primate to manufacture tools in the wild was the chimpanzee.[20] However, since then, several primates have been reported as tool makers in the wild" http://en.wikipedia.org/wiki/Tool_use_by_animals http://en.wikipedia.org/wiki/Tool_use_by_animals
