Discuss evolutionary explanations of human aggression One evolutionary explanation of human aggression is infidelity and jealousy. This suggests that sexual jealousy is one of the main causes for aggression in humans. In the environment of evolutionary adaptation (EEA) our male ancestors would have feared cuckoldry (the reproductive cost that might be inflicted on a man as a result of his partner’s infidelity). It is suggested that such fear of investing in another man’s offspring lead to men adopting mate retention strategies. This is where males have evolved a number of strategies specifically for the purpose of keeping their mate, so that she does not copulate with another male. Such strategies include ‘direct guarding’ (restricting their partner’s sexual autonomy) and ‘negative inducements’ (threatening violence if the woman cheats). An extreme example of mate retention strategies is uxorocide (wife-killing), where the threat of violence becomes very real and goes too far). Buss and Schackelford (1997) support the idea of mate retention strategies as they found that men who suspected that their wives might be unfaithful over the next year exacted greater punishment for a known or suspected infidelity than men who did not anticipate future infidelities. This finding is consistent with the claim in evolutionary psychology that mate retention strategies are evoked only when a particular adaptive problem is faced, in this case the belief that the wife’s infidelity is likely. This can be further supported by Shackelford et al. (2005) who found that men’s use of retention technique was positively correlated with their violence scores. An important application of such research is that particular tactics of mate retention used by males can be an early indicator of violence against the female partner. The findings from these studies can potentially be used
