Define ‘proximate cause’ of behavior and ‘ultimate cause’ of behavior. Describe two examples of proximate cause and two examples of ultimate cause of monogamy in prairie voles.
Proximate cause of the behaviour explains how an organism behaves, physiological, psychological etc. The main focus is on the immediate cause of the behaviour.
Ultimate cause of the behaviour is why animal bahves in the way ot behaves which includes the evolutionary reasons behind the behaviour.
Proximate cause is an explanation which is aimed at how an organism behaves the way it is behaving.
Ultimate behavior is the answer why an organism behaves the way it behaves which is based on the evolution of the behavior.
Proximate behaviour of the Prieri voles monogamous behavior is the release of Dopamine which is involved in reward and addiction and the pleasure related to monogamous mating. There is experimental evidence to proove to this effect.
Ultimate cause of the behavior is lack of number of female in the region, which resulted in mating only with one mate by the male in order to keep the species alive.
