Biologists Observe Gorillas Using Tools

For the first time, biologists have documented gorillas in the wild using simple tools, such as poking a stick in a swampy pool of water to check its depth.

Until now, scientists had seen gorillas use tools only in captivity. Among the great apes, tool use in the wild was thought to be a survival skill reserved for smaller chimpanzees and orangutans.
