A recent study has found that male macaques will readily give up food in order to look at photos of a female monkey’s bottom. Males gave up portions of juice in exchange for a half-second glimpse of a female macaque’s genitals and anus. “Virtually all monkeys will give up juice to see female hindquarters,” says the leader of the study, Robert Deaner. “They really value the images.” The males would also give up juice in order to look at faces of the males in their troop, presumably in order to gather social information about their companions and rivals. But they would only give up very small portions of juice compared to what they were willing to sacrifice for a half-second glimpse of a female’s behind.
