Sociality
(重定向自Subsociality)



Sociality is the degree to which individuals in an animal population tend to associate in social groups and form cooperative societies.
Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators selected this behavior in wasps of the family Vespidae.
