== Causes of sexual dimorphism == | == Causes of sexual dimorphism == | ||
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> | Since males and females are mostly subject to the same survival selection, one would expect them to be very similar.
