Sexual dimorphism. Although, it’s a lot less in humans now than it used to be in our ancestors. Sexual dimorphism is usually a result of intrasexual selection. This is when organisms of the same gender compete over the right to mate with the opposite gender. This competition allows sexual selection to take place. Larger males will win more often and as a result pass on their genes to their sons who will also grow larger. Sexual dimorphism isn’t as high in humans because there isn’t much physical competition over mates and there is also female competition with male choice in our societies.
