Adaptive social behavior is a term used to describe situations where, in a social group, each individual has a feature that helps the whole group and itself. This group, to which the individual belongs, allows each member of the group to have a freedom of articulation of internal and external factors that allow the satisfaction of the group's needs as a single entity, allowing this group to have control, self-efficiency and autonomy that allow your survival.
This type of behavior can be seen in animals that flock as Wolves, fish, ants.
