** Humans' sexual dimorphism isn't as great as that of our near relatives. Gorilla and orangutan males are enormous compared to the females, while male and female gibbons sport different colors of fur, plus an inflatable throat pouch for males of some species. It's even more extreme in the larger monkeys, such as baboons, mandrills, or proboscis monkeys. |

** [[Male Gaze|Boobs!]] Er, to elaborate, human females are about the only creatures with naturally permanently swollen breasts, and they don't even need to become pregnant for them to get like that (pregnancy just swells them ''more''). Other mammalian females have rather flat teats until they get pregnant. ([[Pettanko|Though some human women don't grow much in this area, either.]]) |

** Also, human male penises are [[Gag Penis|gigantic]] compared to other primates (yes, even your [[Teeny Weenie]] is massive compared to a gorilla's), leading some to believe that before the advent of clothing they, like human breasts now, served as a [[Bigger Is Better in Bed|sexual display]] in addition to their other functions. |

** The recently discovered fossil of an adult male ''Australopithecus afarensis'' revealed him to have been five to five-and-a-half feet tall. Compared to his female conspecific Lucy, at three-and-a-half feet, this is quite a substantial size difference between sexes, even if it's assumed he was tall and Lucy was short for their species. |
