What are your thoughts about the following statements? Also, what is you answer to the question: “Are we polygamous or monogamous by nature?”
“About 78% of human societies are polygamous, in which some men marry more than one wife.[2] Only 22% of societies are strictly monogamous. No modern societies are polyandrous, in which one woman marries several husbands (not counting extramarital sex, and a poor region of India and Tibet where women marry brothers because the work of several men is needed to provide resources to raise a family). Only 3% of mammal species in general are monogamous, although at least 15% of primate species are.[3] In historical terms, it is monogamy that is in need of explanation, not polygamy.[4]
