Ape tantrums: Chimps and bonobos emotional about choice

Like many humans, chimpanzees and bonobos react quite emotionally when they take risks that fail to pay off.

This is according to researchers from Duke University in the US, who developed decision-making games that the apes played to earn edible treats.

Some animals that lost the game - receiving a bland piece of cucumber rather than a preferred piece of banana - reacted with what looked like the ape equivalent of a tantrum.

BBC science reporter Victoria Gill explained the findings.
