Names are universal throughout human cultures and across different languages . They form a immense part of our identity and aid us communicate with each other , but personalnamesare considered a uniquely human matter . Now , new research has suggested that wildAfrican elephantscould speak each other with individual specific phone call – the equivalent of a name – with enthralling implications for the evolution of language .
The young enquiry analyzed telephone call from wild elephants in two areas of Kenya : the greater Samburu ecosystem to the Second Earl of Guilford , and the Amboseli National Park to the south . The final dataset contained around 470 freestanding elephant calls . There were 101 unique callers and 117 unique receivers . The researchers only include calls manoeuver at a individual case-by-case elephant , and for which the receiver could be identified .
The team measured the acoustical features of the elephant fathom and ran a serial of statistical tests on the data , to see if it was possible to presage the identity of the liquidator from the call . And indeed , this was find to be the case , as the team writes : “ [ R]eceivers of calls could be correctly name from call structure statistically importantly better than fortune . ”

One aspect the squad were particularly interested in was whether the calls mime the receiver ’s own vocalizations . This has been observed inother species , such asdolphins , which can learn each other ’s case-by-case outspoken label and answer to their own recording label when they see it .
What was fascinating about the elephant datum , though , was that the authors witness limited evidence that the telephoner were imitate each pass receiver ’s own call .
" Our determination that elephants are not simply mime the audio relate with the person they are calling was the most intriguing , " tell field source Kurt Fristrup in a affirmation seen by IFLScience . " The capacity to apply arbitrary sonic label for other someone suggests that other kind of labels or descriptors may exist in elephant call . "
The authors also took 17 of the elephant and play them recordings of call that were originally treat to them to see how they responded . “ Further supporting the existence of vocal labels , ” the authors compose , “ national near the loudspeaker system more quickly [ and ] vocalize more quickly [ … ] in response to test playback than control playbacks . ”
Thankfully , it ’s improbable the elephants were troubled by these frivolity outcry , as first writer Michael Pardo say : " They were likely temporarily confused by the playback but eventually just dismissed it as a strange event and went on with their lives . "
Overall , the author concluded that this could well be the first grounds of a non - human species using a human - corresponding designation system to refer to other individuals . As to why this might turn out in elephants specifically , there are some clue we can glean from their social structures .
“ [ D]ue to their fission - fusion social dynamics [ elephants ] are often separated from their closely bonded societal partners , ” the authors excuse , refer to elephant ’ tendency tosplit themselves up into smaller partiesthat can then combine together to form large groups , sometimes hundreds - strong .
“ [ V]ocal label in all likelihood allow elephant to pull the attention of a specific distant receiver , ” the authors uphold , also noting that the label only cut back up in a minority of vocalizations , likely because in many contexts there is no want to use them .
There ’s also a cuddlier vista to all this : call each other by their figure could be a way of enhancingsocial bonding , the authors submit , as is the case with human . The authors note that the “ findings raise challenging questions about the complexity of elephant social cognition , ” and thus spread out up a captivating new boulevard for research worker to explore .
Sadly , that likely wo n’t extend to us being able to have a New World chat with an elephant , much as we might require to .
" It’stough to live with elephants , when you ’re trying to share a landscape and they ’re eating crops , " said senior author George Wittemyer . " I ’d like to be able to warn them , ' Do not come here . You ’re going to be killed if you come here . ' "
