Mating systems, intrasexual competition and sexual dimorphism in primates

Many primates are sexually dimorphic. Collectively, sexual dimorphism refers to any character – behavioural, morphological or physiological – that differs between the sexes. Some primates show conspicuous differences in pelage and skin colour, and numerous musculoskeletal differences have been documented for a wide variety of species. However, most comparative studies of primate sexual dimorphism focus on body size and canine tooth size.
