Chimpanzees change accent to fit in
It has been commonly observed among people that their accents change a bit when they live in a different area with different accent long enough. However, a recent research revealed that the same is true in the case of chimpanzees too.
Katie Slocombe of the University of York said, “Our study shows that chimpanzee referential food calls are not fixed in their structure and that, when exposed to a new social group, chimpanzees can change their calls to sound more like their group mates.” It was found that Chimpanzees have special grunts for different types of foods and the fellows understand clearly what calls mean what food is being made available.
When a group of chimps from another zoo were merged with the ones in the Edinburgh zoo, it was found that they altered their grunts for indicating Apple. Stuart Watson from the University of York also said that the scientists think that it was quite easy to listen to how the two groups called in different ways to ask for apples in 2010 and by 2013, the ones from Dutch started making grunts in a similar fashion to those that were already in Edinburgh.
This short evolutionary distance between humans and chimpanzees, that is five to seven million years, scientists say that it suggests that the most recent ancestors of the human race have the building block of language in them. Simon Townsend of the University of Zurich said that it would be exciting to try and find why the chimpanzees are changing their accent when paired with a different group.
