[43] [44] [45] [obsolete source] Chimpanzees, which have a promiscuous mating system, have large testes compared to other primates. Gorillas, which have a polygynous mating system, have smaller testes than other primates. Humans, which have a socially monogamous mating system, have moderately sized testes.
Scientists have documented what appear to be the first-ever lethal chimpanzee attacks against gorillas, according to a new study. Chimps documented attacking and killing gorillas in the wild for ...
Sexual dimorphism can manifest itself in many different forms. In male and female primates there are obvious physical difference such as body size or canine size. Dimorphism can also be seen in skeletal features such as the shape of the pelvis or the robustness of the skeleton. [3] There are two mating systems in the sexual selection of primates.
Studies show modern women tend to fall for guys with Neanderthal-like facial features, which explains why Brad Pitt is such an international heartthrob. Now ladies in Japan are taking this ...
