Abstract: AssessmentThis is a valuable study that tests the functional role of food-washing behavior in removing tooth-damaging sand and grit in long-tailed macaques and whether dominance rank predicts level of investment in the behavior.The evidence that foodwashing is deliberate is compelling, but the evidence for variable and adaptive investment depending on rank, including the fitness-relevance and ultimate evolutionary implications of the findings, is incomplete given limitations of the experimental design.Overall, the paper should be of interest to researchers interested in foraging behavior, cognition, and primate evolution.
