Scientists in Kenya wondered if wild elephants call each other by name, a bit like people do. Almost no animals can do this.
They recorded 469 elephant rumbles and, for each one, knew which elephant was calling and which elephant it was for. Using computers to find patterns, they noticed that each call seemed to have a special sound linked to the elephant it was meant for, like a name. This is different from dolphins and parrots, which copy each other's sounds instead.
To check, the scientists played the calls back. An elephant reacted more strongly to a call meant for it. That is good evidence, but it does not mean scientists have learned the elephants' actual names. It is an exciting clue that needs more study.
