Chimps exchange food for sex

Male chimps that are willing to share the proceeds of their hunting expeditions mate twice as often as their more selfish counterparts.

This is a long-term exchange, so males continue to share their catch with females when they are not fertile, copulating with them when they are.

Meat is important for the animals' diet because it is so high in protein. Since female chimps do not usually hunt, "they have a hard time getting it on their own," explained Dr Gomes.

The "meat for sex hypothesis" had already been proposed to explain why male chimps might share with females.
