Social rank may determine if animals live fast, die young Dartmouth study of macaques suggests leaders put immediate survival above longevity.
Dominant monkeys brush food on their fur before eating it, along with mouthfuls of sand, while lower-ranked monkeys obsessively wash their food in the surf.
Study supports the disposable soma hypothesis, which proposes that animals sometimes prioritize immediate survival and reproduction over longevity.
Food-washing among primates is not common, researchers say.
The monkeys that washed their food devoted an average of five seconds to over a minute to each cucumber slice.
The average amount of time spent just brushing sand off a slice was effectively zero .
The researchers determined social rank using established methods of observing how the animals interact.
