What is a potential consequence of evolutionary pressures on social behaviour like aggression?

• A. Aggressive tendencies may be favored in some contexts
• B. Genes for morality universal
• C. All traits equally beneficial
• D. Culture has no impact

Answer: (A)

Evolutionary pressures shape social behavior by favoring traits that improve reproductive success in specific environments. Aggressive tendencies can be advantageous for securing resources, defending offspring or territory, or increasing status, so in those contexts such tendencies can be selected for. But what’s beneficial is context-dependent: aggression may help in some situations and be costly in others, so there isn’t a universal pattern across all environments. This perspective also makes clear why higher-level claims like “morality is encoded by universal genes” aren’t supported—morality emerges from a mix of biology and cultural influence and isn’t fixed across all people or cultures. Likewise, not all traits are equally beneficial; natural selection favors those that boost fitness in a given setting, leading to variation. Finally, culture matters a lot in shaping how aggression is expressed, regulated, and perceived, so social norms and learning interact with evolution rather than being irrelevant.
