Researchers used artificial intelligence algorithm to analyse calls by two herds of African savanna elephants in Kenya

Elephants call out to each other using individual names that they invent for their fellow pachyderms, according to a new study.

While dolphins and parrots have been observed addressing each other by mimicking the sound of others from their species, elephants are the first non-human animals known to use names that do not involve imitation, the researchers suggested.
