Pretty cool
Wild gorillas seen to use tools
Gorillas have been seen for the first time using simple tools to perform tasks in the wild, researchers say.
Scientists described how gorillas in forests in Congo used sticks to test the depth of muddy water and to cross swampy areas.
The head of the US and German team said the discovery would cast new light on how humans and other species evolved.
Captive gorillas have been known to use tools, but scientists say they are merely copying their human captors.
