Based on an analysis of more than 400 elephant rumble recordings, researchers determined that elephants, much like humans, use specific, unique sounds to refer to one another.

African elephants are among the smartest animals on Earth . Now , a young work evoke they could be even more level-headed than most people take in . The study , print in the journalNature Ecology & Evolution , arrogate elephant do something few other wild animals do : call each other by their names .
These names come in the word form of low-toned rumbles called out over the vast expanse of the savanna . Researchers described this rumble as “ a harmonically fat , small - frequence speech sound that is individually trenchant . ”

In short , these are name - like sounds used by elephants to identify one another .
This find , researcher suppose , “ radically expand the expressive power of nomenclature ” and “ could have important implications for our understanding of language evolution . ”
How Elephants Use Low Rumbles To Identify Each Other
While it is common for humans to address each other by an individualized name , this behavior is seldom observed in other animal species . dolphin , for example , come in up with their own name calling , called “ signature whistle . ” parrot likewise can copy signature call made by an individual as a means of addressing them .
In this sense , human name differ because they are not impersonation of strait made by the referent , but rather individualized , abstract sound used to address an someone .
“ dolphin and parrot call one another by ‘ name ’ by imitating the signature call of the addressee , ” Michael Pardo , the study ’s tip author and a Colorado State University postdoctoral researcher , say in a press release . “ By line , our datum suggest that elephants do not rely on imitation of the receiver ’s telephone call to turn to one another , which is more standardized to the way in which human name forge . ”

In their study , researchers analyzed 469 elephant rumble samples sorted into three distinct salmagundi : contact , greeting , and caregiving .
“ Contact grumbling are long - distance call produced when the caller-up is out of sight and more than ~50 m from one or more social affiliates and attempting to reinitiate liaison , ” study authors explain . “ Greeting rumble are affiliative call produced when one individual border on another to within touching distance . Caregiving rumbles are affiliative call acquire by an adult or puerile female while suckling , comforting , or rousing a sura . ”
A Phenomenon Previously Only Seen In Humans
George WittemyerResearchers recording elephant vocalizations in Kenya .
The researcher spend four years studying African elephants , admit 14 month of field work in Kenya in which researcher follow the animals in a fomite and record their vocalizations .
The squad collected 469 sound samples and processed them through a motorcar - find out example . Researchers were able to place the recipients of 27 pct of those calls , potential because in those instance the elephant was being called by its “ name . ”
The researchers then played back recordings of the elephant ’ calls out loud and observe the answer of 17 elephant in the wilderness . Astonishingly , the elephant responded affirmatively to birdsong addressed to them , but had far weak reaction to recordings of call made to other elephant .
Of naturally , more research is want to officially confirm these newfangled findings . Still , if this new data is anything to go on , researchers may have just get word a fundamental new landmark in the story of language development .
“ If further research underpin the absence seizure of receiver caricature in elephant vocal labels , then investigating the societal context , acoustic structure , and ontogeny of vocal label in elephants may shed luminousness on why elephant and humans formulate non - onomatopoeical vocal labels in contrast to other species know to vocally label conspecific , ” research worker pen .
“ Our effect also have significant entailment for elephant noesis , as invent or study sounds to address one another hint the capacity for some stage of emblematical idea . ”
