Orangutan communication resembles a game of charades, a study suggests.
Researchers from St Andrews University have shown that the animals intentionally modify or repeat their signals to get their messages across.
The scientists said they believed all great apes could have this capability, suggesting that the skill may have evolved millions of years ago.
The study, which is published in the journal Current Biology, involved six orangutans living in two zoos.
