【 摘 要 】

A recent paper by Lefevre et al. (2014) in PLoS One reported that individual differences in facial structure predicted assertiveness in brown capuchin monkeys (Sapajus spp). Specifically, variation in the facial width-to-height ratio (fWHR) was positively correlated with alpha status and a composite measure of assertiveness. This novel finding adds to a growing body of evidence indicating that variation in facial structure reliably maps onto individual differences in dominance-related phenotypes.
