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 and at higher rate than men).<ref>https://www.researchgate.net/publication/41391479_Strategies_of_Human_Mating</ref> | 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 and at higher rate than men).<ref>https://www.researchgate.net/publication/41391479_Strategies_of_Human_Mating</ref> | ||
Sexual dimorphism | Sexual dimorphism and dimorphic mate preferences result in different kind of [[intrasexual competition]] for each sex, e.g. men competing with resources and physical power, and women competing merely in looks and with more gossip rather than physical power. Intrasexual competition, in turn can increase sexual dimorphism, e.g. by males evolving to be stronger and taller to achieve high status. | ||
