Macaque grape experiment tests whether monkeys feel disgust
Original: Will a macaque eat a grape sitting on a pile of poo? A study on germophobia
Researchers put a grape on a pile of faeces and offered it to macaques to see whether the monkeys would refuse food over contamination concerns. The experiment is part of a study on how strongly primates instinctively avoid germs. Findings are drawing wide attention, with readers debating what the results say about the evolutionary roots of disgust and hygiene behaviour in humans.
Why now: The counterintuitive experiment on primate disgust responses is newly published and sparking discussion about the origins of germ avoidance in humans.
