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.

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.

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.
