Document Summary

Study of the biological basis of social behaviour in organisms. Abridgement of the rights of others forcing him to surrender something he owns or might have attained. Between or among individuals to impose their values or behaviour on other individuals. War for resources and domination, power, greed. Dislike ad suspicion of unfamiliar individuals or groups. Parents killing own young to improve chances of other young. Non -relatives killing young to bring females into heat. All organisms have aggressive patterns both defensive and offensive. Survival value and has a genetic basis. But in social species, which also depend upon cooperation, aggression must be balanced. Macaque monkeys lower in the social dominance hierarchy makes their immune system less effective. Low social status in humans and other primates depressed the immune system and leads to health problems. If the amygdala is stimulated, it triggers memories and motivation, especially fear.
