What is the significance of monogamy in human relationships?

• A. Monogamy may help avoid cuckoldry and ensure male investment in offspring.
• B. Monogamy guarantees exclusive sexual fidelity in all cases.
• C. Monogamy ensures universal parental certainty.
• D. Monogamy eliminates jealousy altogether.

Answer: (D)

Monogamy matters in human relationships because it shapes paternity certainty and parental investment. When partners form a largely exclusive bond, the risk that a male’s resources go to offspring not fathered by him (cuckoldry) is reduced, which can encourage greater investment in the shared offspring—money, time, protection, and caregiving. This idea captures why monogamy is often discussed as having a role in motivating fathers to invest in their children.

But monogamy does not eliminate other realities. It does not guarantee exclusive sexual fidelity in all cases, it does not ensure universal parental certainty, and jealousy remains a natural emotion that can persist even within monogamous arrangements. So the significance is about how monogamy can reduce certain paternity-related risks and promote investment, not about erasing all consequences or guaranteeing absolute outcomes.
