Chimpanzees have particular grunts for various fruits and in time eventually they can get accustomed with a new language with new sounds after uniting with a new community of of their clan.
Study shows that a community of chimpanzees had a particular grunt for apple in Edinburgh Zoo, whereas the group at Beekee Bergan Safari Park had a different sound for the fruit. 3 years after joining a Scottish group, a clan of Dutch chimps adapted to the new grunt of the new group.
To be more specific, when two communities of chimps come together, they “converge” their way of remarks. Researchers from the Universities of York in England and Zurich in Switzerland states that their research is the first to give confirm that chimps can learn referring to particular objects only.
Chimpanzees utter distinct sounds in the form of grunts when they find certain types of foods, and their peers understand what those grunts mean.
Up until a time, scientist assumed that chimps didn’t have much command in their structure of calls and thought that there was not much differentiation in the words and expressions for different emotions.
In the latest research as publish is the journal Current Biology, the scientists had the rare chance to observe whether chimps could alter the call for food while some adult a group from Netherlands joined the ones residing at Edinburgh Zoo in 2010.
Prior to coming together, scientists noticed that each community had their own languages and also that preferences for the same word or emotion were not the same.
After 3 years of integration, the new chimps renewed their grunt for apples. This means they have taken on the other group’s dialect. Some researchers argued that non-human primates don’t have much control on sounds they use and that shown they don’t hold the expertise of the language. Though, Dr. Katie Slocombe, of the Department of Psychology at the University of York, and contemporaries has defied this long-standing statement saying that imprisoned chimps had learned grunts that refers to particular foods. Moreover, chimps also have the proficiency to adapt the pattern of useful grunts with time that they hear from the new community.
Researchers have recorded the Dutch chimp’s apple grants both before (2010) and after (2011) integration and then lastly in 2013.
Dr. Slocombe and his team reports that just a year after the integration, the new occupants yet do not change their sounds. It was not till 2013, when their social network analysis
Dr. Slocombe and team reported that just one year after integration the new residents had not changed the sound of their “apple” grunt – it wasn’t until 2013 “when social network analyses pointed out close friendships were formed between candidates of the original subgroups.
Dr. Slocombe said “An extraordinary feature of human language is our ability to reference external objects and events with socially learned symbols, or words. These data represent the first evidence of non-human animals actively modifying and socially learning the structure of a meaningful referential vocalization.”
“Our findings indicate that primate referential call structure is not simply determined by arousal, and that the socially learnt nature of referential words in humans is likely to have ancient evolutionary origins.”
Dr. Simon Townsend, who works in the department of Evolutionary Biology & Environmental Science at the University of Zurich, added:
“These findings might shed some light on the evolutionary origins of these abilities. The fact that both humans and now chimpanzees possess this basic ability suggests that our shared common ancestor living over 6 million years ago may also have been socially learning referential vocalizations.”
