Is Monogamy Natural?

Vaunted in the mainstream media, two new reports from the Pew Research Center report and the National Survey of Families and Households indicate that couples become bored and unhappy sooner than was previously thought: more like three years into their togetherness than seven.

For species whose slow-growing offspring statistically stand better chances of survival with two parents providing double-sustenance, double-vigilance, double-protection and double-support, monogamy makes scientific sense. But because it's so difficult "to live in the same nest for fifteen years," as Quirk puts it, "love is an instinct coded into our genes."

Fool yourself all you want about free will.

"We inherited the desire to fall in love," Quirk insists, because that soul-baring, die-for-you devotion helped our ancestors "raise babies on the dangerous Pleistocene savanna."
