Document Summary
Sociobiology: study of the biological basis of social behavior in organisms. Aggression: abridgement of the rights of others forcing him to surrender something he owns or might have attained. (fighting, hostility, intimidation, attack). Predator prey interactions, interspecific competition (lion vs hyena) Competition for natural resources, red kites fighting over food. Moral aggression: between or among individuals to impose their values or behavior on other individuals. (ex: nazi aggression, gays) Territoriality: defense of a physical space, ex: red winged black birds, fur seals. if you don"t fight for territory you don"t mate and leave their genes behind, so aggression does have selective advantage here. Social dominance hierarchies: fights for dominance- access to resources for mates" ex: chickens. You are the one that gets to mate, and don"t get beat on. there is strain on alpha because they always have to be on guard. Macaque monkeys lower in the social dominance hierarchy makes their immune system less effective.
