Which statement most accurately reflects the evolutionary basis of behaviour and the role of culture?

• A. Behaviour is determined solely by genetic factors with little cultural influence.
• B. Behaviour has evolved to promote survival and reproduction, but culture and society can significantly affect aggression and reproductive behaviour.
• C. Cultural norms fully determine aggression and reproductive behaviour, with little influence from biology.
• D. Evolutionary explanations ignore the effects of culture and morality.

Answer: (B)

Understanding how behaviour evolves and how culture shapes its expression: behaviours that helped our ancestors survive and reproduce tend to be passed on, giving us underlying biological drives. But culture and society layer on norms, values, and practices that can significantly alter how those drives show up in real life, including aggression and mating behavior. So the best statement recognizes that behaviour has evolved for fitness, while culture can modulate its expression in different contexts. Biology provides predispositions that steer how we respond to threats, compete for resources, or seek mates. Culture, in turn, sets what is considered acceptable, how conflicts are managed, and what motives are rewarded or punished. Together they form the full picture: evolution explains why certain tendencies exist, and culture explains when, where, and how strongly they are expressed. Other views miss something crucial. Saying behaviour is determined solely by genetics ignores the powerful role of cultural learning and social norms. Claiming culture fully determines aggression and reproductive behaviour overlooks the biological bases and evolved tendencies that shape these behaviours regardless of culture. Suggesting evolutionary accounts ignore culture and morality is inaccurate because researchers increasingly acknowledge that cultural and moral contexts interact with evolved drives to shape behaviour.
