A species of ape is on the brink of extinction in central Africa, even though the animals are addicted to sex

Bonobo apes live in Democratic Republic of the Congo (DRC) and often have sex every few minutes.

But because they have quite low fertility, are hunted for their meat and their babies are stolen as pets, their numbers are now perilously low.

The bonobos -- the closest species to humans -- are now classified as "endangered."
