Perkins Gilman argues that the morbid sex distinction is a result of a woman's economic dependence on attracting a male. However, I would suggest that this idea ignores the basic biological and evolutionary effects that have taken place that serve to enhance female sexuality. The incredibly quick growth of the skull of the human baby, evolutionarily speaking, has placed an enormous pressure upon the development of female hips and a high importance on the mere ability to successfully bear a child. As recently as a few hundred years ago dying during childbirth was a common occurence. As such, while men continued to be evolutionarily favored to be strong and powerful, the single most powerful evolutionary pressure on women was to be able to have children. As a result of this, gender distinctions became much greater between male and female humans than in other species.
Will we ever come to a point where men and women are physically equal in terms of strength, speed, and size, given the basic evolutionary and biological differences which distinguish men and women?
