In most mammals, juvenile males tend to be more vulnerable to starvation than females and consequently experience a higher mortality. This has been attributed to selection on high male growth rates in response to strong...

...Peter M. Kappeler Many primatologists believe that there is no sexual dimorphism in body size in prosimian primates. Because this belief is based upon data that came from only a few species and were largely flawed in some aspect of sample quality, I re-examined the extent of sexual dimorphism...

.... Because some 93% of the variance is at the level of species or below, sex difference in juvenile mortality is probably not a phylogenetically conservative trait. Sexual dimorphism in body size, by con­ trast, is a conservative trait among anthro­ poids [4], probably being most variable at the level...

.... Skull weight seemed to be one such possibility. We weighed 447 skulls from different genera and species of African Cercopithecidae. Whereas the t test confirmed the existence of a sexual dimorphism at this level, discriminant analysis gave a discriminating value to the weights of skulls. Folia primatol...
