A recently-published study claims that the sounds of African elephants may have a lot more significance than humans think. The research, which was published in a journal called Nature Ecology and Evolution on Monday, found that African elephants call each other unique names. The study explains that researchers followed elephants around to observe how they communicated to each other, particularly by taking careful note of which elephants called out sounds and which elephants appeared to respond.
Researchers then used a machine learning model to see if a computer program could determine which elephant which was being addressed at a time. The machine only guessed the correct elephant around 28% of the time. An author of the study told the Associated Press that researchers were not expecting an astronomically-high percentage of correct guesses.
Experts also played recordings of the animals' 'names' to individual elephants in order to observe their reactions. The elephants responded strongly by flapping their ears, lifting their trunks and appearing energetic when they heard their names. Elephants are one of very few species that are believed to call each other by unique names, other than humans. Dolphins and parrots are believed to also use names within their species.
Wildlife biologists have long known that elephants are social creatures, but one of the study's co-authors says that the research 'crack open the door a bit to the elephant mind.' 'Elephants are incredibly social, always talking and touching each other — this naming is probably one of the things that underpins their ability to communicate to individuals,' Colorado State University ecologist George Wittemyer told the Associated Press.
