The mother elephant looked annoyed. The herdA group of animals. is about to set off for the next waterhole, but her son is nowhere to be seen. Typical! All she can do is call his name: "Kala Nag!"

This is just a story. But according to a new study by scientists, it may not be far from reality.

Researchers used AIA computer programme that has been designed to think.  to look at over 400 calls between elephants in KenyaA country in East Africa with a population of nearly 54 million people. .

The AI system picked out sounds that could have been names. The scientists then played these back to the elephants they believed they belonged to. They wanted to see whether the elephants would react - and they did!

Until now, we have not known about any other animal other than humans that talk to each other with names.

The discovery is very important. If elephants are clever enough to learn each other's names, they may be able to think in a similar way to us.

And some think that if elephants think just like us, they should have rights just like us too.

Should they have human rightsThe basic rights and freedoms that belong to every person in the world, from birth until death. They apply regardless of where you are from, what you believe or how you choose to live your life. Some have called for animals and even natural phenomena like rivers to have some form of human rights.?

Yes! Elephants are a lot like us. They have big brains and can remember things. They also grieveFeel sad about the death of someone you cared about. when other elephants die. They should have rights just like us.

No! Humans are clearly different to all other animals. We should treat animals with kindness, but we should not treat them just like people.
