One gene which has been linked to aggression is the gene coding for the production of monoamine oxidise A (MAOA). Brunner et al 1993 studied the men in a family with a tradition of violent men‚ they discovered that the gene responsible for producing the enzyme MAOA may be associated with aggressive behaviour. The normal gene that makes an enzyme which metabolises hormones and neurotransmitters (including adrenaline and noradrenaline). With a mutated gene there is less enzymes and so the levels of

The evolutionary approach believes that human intelligence evolved due to the demands of the environment creating pressure for increased intelligence. Larger brains may have evolved to allow individuals to cope with the demands of social living. However having a large brain involves costs-larger brains use a higher proportion of an individual energy. Humans use 22% of their energy sustaining the brain compared with only 8% of chimpanzees. According to Kliniwoska‚ if brain size equated to intelligence

humans‚ as well as other animals‚ are innately aggressive and this often leads to violence when conflict situations arise. Indeed‚ conflict is an expression of the aggressive component of our biology. Aggression is a fighting instinct directed against people and it often leads to violence when conflict situations arise.

An evolutionary perspective of attachment was researched by the famous John Bowlby in 1969. Bowlby observed both humans and mammals. Bowlby ’s theory is an evolutionary theory‚ he emphasised that attachment had evolved‚ which means it was not something that was taught‚ because of its survival and reproductive

The human brain is very unique. The concept of evolutionary psychology explains that human behavior is largely influenced by their evolutionary ancestors through six theories and methods. Evolutionary psychology proposes that a lot of human behavior can be explained by the change of the physical and social environments through time. It argues that “much of human behavior is the output of psychological adaptations that evolved to solve recurrent problems in human ancestral environments.” (Evolutionary

Evolutionary psychologists view human behavior and psychological traits as a result of evolutionary adaptation in response to reproductive needs – much like the concept of natural selection applied to reproduction‚ or sexual selection. Drawing from this perspective‚ evolutionary psychologists and professionals seek to explain the differences between male and female dating and mating rituals and sexual attitudes and how they have evolved throughout the centuries. For example‚ researchers employ the
