What is Presociality?

Presocial animals have close family relationships, more than just sexual interactions with members of the same species. However, they do not form the extreme [[colony (biology)|colonies]] of [[eusocial]] [[insects]], such as [[ants]]. Presocial animals can live together and take care of their young. They may have some division of labor, but they do not have all the three essential traits of eusocial animals, which are: #There are many generations that are alive at the same time. #There is extreme [[division of labour]]. Some animals may be specialised for a certain function. Some animals may be [[sterile]]. #The older animals cooperate to care for the young. Presocial behavior is much more common in the animal kingdom than complete eusociality. Examples include [[Canidae|canines]] that live in packs, numerous [[insects]], especially [[hymenoptera]], [[humans]], many [[birds]], [[chimpanzee]]s, and many other animals that display social behavior. The concept of presociality can be further divided: *'''Subsocial''': parents interact with young. This applies to all [[mammals]] without exception, almost all [[birds]], many [[reptiles]] and [[fish]], and quite a few [[insects]]. *'''Parasocial''': individuals of the same generation live in a single, cooperative dwelling and interact with each other **Communal: each individual care exclusively for her or his own young **Quasisocial: individuals care cooperatively for all brood; however, all members of the colony are reproductive **Semisocial: a few individuals reproduce, yet the arrangement is not quite eusocial. For example, adult generations might not overlap, the reproductive dominance might be temporary. Among the Vespid [[wasps]], the pressures
