Gorillas are born with an international sign language of gestures that they use to communicate，says a new study from the University of St Andrews in Scotland.

From beating their chests to putting objects on their heads，shaking their arms，and even bouncing on all fours，the animals use more than 100 gestures to communicate with each other

Professor Richard Byrne，a psychiatrist involved in the research，says it was hard to figure out the meanings of the gestures.

“We don't really know what the animals are thinking. Often the gestures have more than one meaning，depending on the context，”says Byrne.

The study showed that the gorillas did not learn the ges­tures from each other，as had been expected，but performed them instinctively (本能地).

“Everyone had assumed different groups of gorillas would learn different gestures，”he says. “But that's not what we found. The more sites we went to ,the more we saw the same gestures being used. They seem to be naturally equipped with a pretty complex system of communication.”

The study also found that gestures were performed with close attention to the potential audience，so that silent sig­nals，for example， were only given when other apes could see them. Other gestures，such as the "disco arm shake" were only ever seen directed towards humans.

Byrne believes that the findings may explain how the human language developed.

“There has always been speculation（猜测）that the origins of the human language might lie in gestures，”he says.

“Many researchers have therefore studied the gestural communication of the great apes for clues to the evolution­ary origins of human gestures，”he adds.

Several studies have shown that great apes are capable of imitating gestures. However，the scientists found that what appeared to be copies of human actions were actually gestures the apes were already able to make themselves. They're “reusing” gestures from their own repertoire，not learning new ones.
