These include direct guarding restricting her movements of the female and negative inducements to prevent her straying financial control, threat of violence if they are unfaithful or even so much as look at another man, etc. A strength of the evolutionary approach is that a study by Foldesi supports xenophobia as a cause of group aggression.
Infidelity triggers sexual jealousy which is an evolved adaptive response to infidelity. Retention strategies can also include violence against the woman. Also, if homicide has evolved then we would expect all people to behave in a similar way, however 3 different people may react to the same situation in 3 different ways — e.
Sexual jealousy as an evolutionary response has significant practical applications for society. Outline uxoricide as an accidental killing when control has gone too far.
One cause of aggression could be a lack of resources. Homicide can also be due to sexual jealousy.
Are men hard-wired to be jealous? It has been argued that women practise retention strategies and carry out assaults on their partner as often as men do. Two neurotransmitters in particular are thought to be important in the control of aggressive behaviour, these are serotonin and dopamine.
Because of this, using retention strategies and violence may not be adaptive in some cases. Daly and Wilson established a link between sexual jealousy and aggression. Testosterone has been shown to correlate with the level of aggression displayed by humans and animals.
It is hard to generalise these findings to humans however, as many animals do not have the same capacity for cognitive processing and self-awareness and animal behaviour tends to rely more on biological factors. Bertram found that lions killed the offspring of other males to ensure a higher likelihood of his own offspring surviving and his genes being passed on.
This suggests that violence is not a universal response to sexual jealousy, and thus that it is not completely evolutionary. This suggests a lack of resources unemployment leads to less money, less food, poorer housing etc and the inability to have a long-term relationship lead to increased social competition and men murdering men.
Women's responses also confirmed this, with evolutionary male retention strategies leading to violent behaviour towards them.
Making A level psychology easier Evolutionary explanations of human aggression Jealousy and infidelity How can evolutionary pressures and natural selection explain human aggression? Similarly, a woman may be less likely to accurately report her partner as abusive if she fears recriminations from him, or she may even choose to deny the truth about his behaviour because acknowledging it could mean the end of her relationship with him.
Female victims of partner rap are likely to have engaged in extra-marital sex Shields et al. Discuss evolutionary explanations of human aggression.
Men had higher activity in the hypothalamus and amygdala. He loses a partner which damages his reproductive fitness and another male gains his partner, increasing his own fitness.
Another reason that men kill men is to defend their status in a peer group. In our evolutionary past, loss of status could be harmful for survival and reproduction. However, much research of infidelity is alpha biased by maximising the differences between male and female behaviour in sexual jealousy.
Similarly, a woman may be less likely to accurately report her partner as abusive if she fears recriminations from him, or she may even choose to deny the truth about his behaviour because acknowledging it could mean the end of her relationship with him. Neurotransmitters are chemical that allow impulses in one area of the brain to be transmitted to another area.
Discuss the alternative argument to the accidental nature of uxoricide and state why it may be an intentional act. Because of this, using retention strategies and violence may not be adaptive in some cases.
Sexual jealousy is a further motivator in male-male homicide.Discuss Evolutionary Explanations of Human Aggression (8+16) The evolutionary explanation to aggression suggests that aggression is an evolved adaptation designed to enhance reproductive fitness (survival and passing along genes).
Discuss One or More Explanations of Adjustment to Old Age Discuss the view that the impact of earthquake hazards depends primarily on human factors Outline the evolutionary process of selection and discuss the relationship between adaptation and environment, using examples from chapter 2 of Mapping Psychology.
