Group Living Animal society – stable group of individuals of the same species that have cooperative relationships outside of mating and raising young. Invertebrates and vertebrates
Advantages to Group Life Protection from predators Increase feeding efficiency Protection from elements Easy access to potential mates
Disadvantages of Group Life Competition for resources Diseases Parasites
Aggression Agonistic behavior Attacks Threat displays Maintains territory Maintains dominance hierarchy
Altruism Individual sacrifices reproductive potential for the benefit of others in the group – Honeybees – Turkeys – Naked mole rats Kin selection
