Document Summary
Individual differences: weakest point of evolutionary perspective. Natural selection is the process by which genes for adaptive traits are replicated, and genes for non-adaptive traits are not. As a result, human nature reflects behaviours which have been adaptive throughout evolutionary history. To study personality from an evolutionary perspective: think about how personality traits might be adaptive. Does a particular trait increase your likelihood of survival? (natural selection) Does a particular trait increase your likelihood of finding a mate and reproducing? (sexual selection) Does a trait influence the likelihood that your relatives will survive (inclusive. Darwin revolutionized biology by proposing a theory of the process by which. More offspring produced than can survive and reproduce. Changes or variants that better enabled an organism to survive and reproduce adaptations are created and changes take place over time natural selection. Descendants inherits variants that led to their ancestors" success lead to more descendants.
