Document Summary
Darwin argued that, over time, organisms originate and become adapted to their environments by biological means. Biological evolution: changes that take place in the genetic and physical characteristics of a population or groups of organisms over time. Many behavioural differences among organisms, both within and across species, correspond to genetic and other biological differences. Understanding these differences and their evolutions allows psychologists to understand behaviour in terms of its possible origins and adaptive signi cance: the effectiveness of behaviour in aiding organisms to adapt to changing environmental conditions. Psychologists might research how past environmental conditions favoured a certain trait and over another and how immediate environment in uences choices. They are interested in understanding both ultimate causes (evolutionary conditions that have slowly shaped the behaviour of a species over generations) of behaviour and proximate causes (immediate environmental events and conditions that affect behaviour)
