Reply to comment by chazwomaq in Biologically speaking, what makes men typically stronger than women? by Erratic_Noman

Size is not a sexual dimorphism in the human species, male and female are relatively similar in size, there are actually many women taller than man. Size, which is linked to strength, makes/made a man go up in the competence hierarchy, which makes him more attractive as a mating partner, which in turn means that the genes responsible are passed on to the next generation.

Humans do show size dimorphism (about 15%), albeit not as much as some other primates, and certainly not as much as elephant seals. There is also substantial dimorphism in upper body musculature relative to lower body, suggesting adaptations for fighting.

The rest of what you described is Darwin's male-male competition and female choice.

Thats a size difference in my eyes, due to a complex mating behavior humans developed over time and male physical aspects is one parameter that played/plays quite a significant role, which also indicates health.. likely the major aspects in mate selection on both sides. And could you please define what you refer to when using the term size dimorphism.

Size dimorphism means a difference in size between the two sexes of a species.
