Which statement best describes the concept of monogamy's evolutionary significance?

• A. Monogamy is a universal requirement for all human cultures.
• B. Monogamy has no impact on offspring.
• C. Monogamy may help avoid cuckoldry and ensure male investment in offspring.
• D. Monogamy guarantees parental certainty in all cases.

Answer: (C)

The idea being tested is how evolutionary pressures shape mating systems like monogamy, particularly in relation to paternity and parental care. Monogamy can be favored when a male’s investment in offspring greatly boosts their survival, but where females might mate with others could undermine that investment if paternity isn’t certain. Holding a partner in a pair bond and reducing the likelihood of extra-pair mating can increase the chance that the male’s care actually goes to his genetic offspring. So, monogamy may help avoid cuckoldry (uncertainty about paternity) and encourage male investment in the offspring, which is advantageous for both partners and their children in many ecological and social contexts. It’s worth noting that monogamy isn’t universal across human cultures, and it doesn’t guarantee parental certainty in every case. But the statement captures the evolutionary motivation: monogamy can align mating strategies with increased paternity confidence and biparental care, improving offspring survival where those benefits are significant.
