GORILLAS - Wild gorillas seen to use tools

The BBC is among many sites reporting the discovery of Gorillas being observed using tools.

Gorillas have been seen for the first time using simple tools to perform tasks in the wild, researchers say.

Scientists observed gorillas in a remote Congolese forest using sticks to test the depth of muddy water and to cross swampy areas.

Wild chimps and orangutans also use tools, suggesting that the origins of tool use may predate the evolutionary split between apes and humans.

There is a video of the gorillas in action on the right side of the BBC page.
