Document Summary

Ethology the study of animal behaviour from an evolutionary perspective. Experiments can distinguish between genetic and environmental influences on behaviour: a means of genetic manipulation; has been used extensively to select for both anatomical traits and behaviour (ex: dog breeders, darwin"s pigeons) konrad lorenz one of the pioneers of ethology ; used interbreeding (or hydridization) of duck species to investigate the hereditary basis of their elaborate courtship delays. ex: the fosb gene on mice the altered neural connections play a part in motivating the mother to retrieve and care for her pups. Genetic control of behaviour is adaptive under many conditions. Imprinting is a rapid form of learning in which an animal comes to make a particular response which is maintained for life to some object or other organism (ex: konrad lorenz and the goslings, emperor penguins) Some behaviours result from intricate interactions between inheritance and learning ex: songbirds and song acquisition.

Thinking of behaviours an organism can adapt, at the very basean action can always be either selfish or altruistic(cooperative).

Usually, selfish behaviour is assumed to be the preferred choiceand the question is how altruistic behaviour comes about.

But if reciprocal altruism can give both participants a higherbenefit than their respective costs (which it usually does), whywould selfish behaviour (in the sense of behaviour which reapsbenefit at another entity's expense) be what we assume to happen?If evolution tends to optimise things, why does it not optimisethis?
