Scottish researchers have identified changes in sounds used by animals to order apples.
Learning other languages is common for humans. But scientists consider the discovery that chimps are also able to understand different sounds of other primates.
Scientists accompanied two groups of chimps that were put together at the Edinburgh Zoo (Scotland). The group of Dutch chimpanzees started using Scottish primate sounds after a while to order apples.

Now scientists want to know if the two groups have understood each other before - and just had different "accents" - or if the different sounds that chimpanzees use to order apples represent two different languages.
