Document Summary
The question: are people naturally inclined to be selfless and altruistic, evolutionary-based theories explain why people might be disposed by nature and biological structures represent mechanisms genetic predispositions are manifested= how and when forms prosocial behav expressed. Disentangling nature and nurture: general strategy det whether type response primarily genetic basis involves looking for similarities in behaviours across organisms, cultures and individuals who are genetically similar but have had very different learning experiences. Darwin"s principles of natural selection: wallace proposed natural selection= 4 simple, interrelated principles, principle of variation- members of species vary in physiological and behav traits. New evolutionary perspectives: early 1960s, some prominent evolutionary theorists began to modify original darwinian model- focus turned away from survival individual person to survival individual"s genes as primary mechanism by which evolution occurs= reconsideration bens altruism for survival. The evolutionary benefits of altruism: members of species who sacrifice lives for other will, on average, have fewer offspring themselves.
