The relationship between facial symmetry and social behaviour in free-ranging long-tailed macaques (Macaca fascicularis).

Primate faces provide critical information for friendship, with facial symmetry allowing display of superior quality. Following findings on increased facial symmetry related to beneficial social interactions in humans, this study hypothesized that such relationship exists for primates. We analyzed...
