Behaviour: the interface of the individual with its environment. Reflex: an action that is performed without conscious thought to a stimuli. Individual selection (an involuntary response: what natural selection is ie. for the survival & reproductive success [fitness] of the individual, not the species. Sexual selection: one source of sexual dimorphism (difference in body form and behaviour between the two sexes of one species, increased individual fitness through obtaining more, or better quality, mates. Reproductive value: total number of offspring that an individual can be expected to produce during the rest of its life. Fluctuating asymmetry: organism(cid:495)s deviation from bilateral symmetry. Hunger causes you to open the fridge door: ultimate, selective advantage (in terms of repro success + survival) that has resulted in the evolution of the behaviour, on an evolutionary timescale, controls of behaviour, proximate: Different roles and time commitments by males and females to offspring = different selective pressures.
