'''Sexual dimorphism''', sometimes known as '''severe gonochorism''', | '''Sexual dimorphism''', sometimes known as '''severe gonochorism''', refers to different appearance and behavior between the sexes within a species. A species with high sexual dimorphism has very noticeable difference between e.g. males and females. For example, the irish elk had such high sexual dimorphism that it was maladaptive, possibly being a major contributing factor in the extinction of the species. | ||
[[Otto Weininger]] argued that in humans, the less sexually dimorphic the genders, the less of a problem [[feminism|female sexual liberation]] becomes. Whereas, if there is high sexual dimorphism in humans, [[feminism|female sexual liberation]] leads to agitation, domestic abuse against husbands, and [[IM LIEK SUCH A NERD LOL|corruption of the arts and science by feminine women only expressing vanity and seeking male attention]]. | [[Otto Weininger]] argued that in humans, the less sexually dimorphic the genders, the less of a problem [[feminism|female sexual liberation]] becomes.

The famous [[MRA]] [[Warren Farrell]] argued that in humans sexual dimorphism could lead to a [[fisherian runaway]] and extinction of the species if females continue to select for, "killer-hunter", type men with the advent of nuclear technology, though some think this is hysterical and overblown. | The famous [[MRA]] [[Warren Farrell]] argued that in humans sexual dimorphism could lead to a [[fisherian runaway]] and extinction of the species if females continue to select for, "killer-hunter", type men with the advent of nuclear technology, though some think this is hysterical and overblown. | ||

Since males and females are mostly subject to the same survival selection, one would expect them to be very similar. Any dissimilarity must hence have a different origin than survival selection. One diver of sexual dimorphism may be [[sexual selection]], i.e. that mate preferences evolved that shaped the phenotype for each sex differently. Another driver may be differential [[Bateman's principle|parental investment]], i.e. that each sex has different sexual investment in the offspring and thus different mate preferences (e.g. women for a providing male) and is subject to different survival selection (e.g. pregnant women dying of different diseases).<ref>https://www.researchgate.net/publication/41391479_Strategies_of_Human_Mating</ref> | |||
