Document Summary

53. 1-what questions do biologists ask about behaviour? ethology: the study of animal behaviour from an evolutionary perspective. most behaviours result from complex interactions between inherited anatomical and physiological mechanisms and the ability to modify behaviour as a result of experience. gene products such as enzymes can affect behaviour by setting in motion a series of gene-environment interactions that underlie the development of proximate mechanisms that enable individuals to make certain behavioural responses. Two experiments in evaluating how genes and experience interact to shape behaviours: deprivation experimentinvestigators rear a young animal so that it is deprived of all experience relevant to the behaviour under study. selective br eeding: means of genetic manipulationhas been used extensively to select for both anatomical traits and behaviour. releaser: an object, event, or condition required to elicit a behaviour: the response of the animal to a releaser may be mechanical or chemical, depends on the motivational state of the animal.
