Finally there is the evolutionary approach which suggests that all our behaviours are adaptive, which means that the reason we do certain things is to help us survive in a certain way; according to this theory AN is a behaviour which helps them survive.

First, however, this holds only for research that conforms to Cosmides and Tooby's theoretical model arguably, Cosmides and Tooby's work on cheater detection, Buss' work on sex differences with regard to jealousy, and Silverman and Eals' work on differences in spatial abilities belong to this category.
