What does it mean to be man or woman in our world today? How do we fill the roles that society defines for us? And is our femaleness or maleness a result of nature or nurture? Dr. Melvin Konner examines the male and female roles and experiences through the lenses of genetics, chemistry, evolution, comparison of species and roles of the sexes across time in his book Women After All: Sex, Evolution, and the End of Male Supremacy. He argues that the last 10,000 years of human history has led to an imbalance between women and men, one that has permeated every sphere of our life and now potentially threatens the world that we live in; that the current state of patriarchal society that we find ourselves in is not in our best interest as a species from an evolutionary standpoint. In order to move forward into a future that has a chance for overcoming our current global challenges, it may be the long suppressed qualities of the feminine that are needed the most.
