Evolutionary Explanations of Human Aggression:
From an evolutionary perspective, humans are most likely to survive if they have access to resources; they can defend their resources and protect their families; and if they can attract and gain access to mates.
Aggression in Males:
- Males are motivated to acquire status since high status males have access to mates and resources for survival.
- High status males are more likely to be selected by females since such males will be better able to guarantee the survival of her and her offspring.
- Low status males have to engage in high risk strategies to enhance their chances of reproduction.
Daly and Wilson (1985) - a review of murders found that the motive behind most conflicts was status. The victims and offenders were most likely to be men of low status and without a mate (unemployed and unmarried). Most victims/offenders knew each other so understood the status of their rival. Those of equal status were more likely to resort to aggression to a bid to move their status above their opponent.
