Gorillas Use Sticks to Cross Over Water

I had two other stories on what chimps do that are very similar to the human interactions ( wars, stone age) . Here is another set of observation from a remote Congolese forest.

"In the first case, we had a female crossing a pool; and this female has crossed this pool by using a detached stick and testing the water depth, and trying to use it as a walking stick," he told the BBC.

The second case saw another female gorilla pick up the trunk of a dead shrub and use it to lean on while dredging for food in a swamp.

She then placed the trunk down on the swampy ground and used it as a bridge.

"What’s fascinating about these observations is the similarity between what these creatures have done, and what we do in the context of crossing a pond," observed Dr Breuer.

"The most astonishing thing is that we have observed them using tools not for obtaining food, but for postural support."
