Question

Give examples of animals showing monogamous and polygamous family formation

Answer 1

About 78% of human societies are polygynous, in which some men marry more than one wife. Only 22% of societies are strictly monogamous. Almost no modern societies are polyandrous, in which one woman marries several husbands (although such societies have existed historically in the Canary Islands, the Himalayas, the Canadian Arctic, and possibly other places). Only 3% of mammal species in general are monogamous, although at least 15% of primate species are.

In historical terms, it is monogamy that is in need of explanation, not polygamy.
