Comparably, in the controversial book Marriage and Civilization: How Monogamy Made Us Human, William Tucker proposes that it is because of polygamy—that causes a similar surplus of young unattached men—that Islam has always been at war with itself and others. “When powerful and successful men are allowed to take more than one wife … as they are in a polygamous society, this creates a pool of unsuccessful men at the bottom of society who are constantly in conflict with the system.”124 This makes sense, even when you look at it from an evolutionary psychology perspective.
