As exobeings can only arise through evolution the roots of their sociality would lie in earlier stages of their biological development. From Earth, we know that animals bond and form communities in different ways, with the common purpose being the survival of the species. This is the basis of their very divergent kinds of behaviour. There is no reason why this should not be the case on an exoplanet as well.

Animals differ widely in the extent to which they interact with each other. Some animals, like certain types of birds, such as albatrosses, remain together as couples to rear their young and return to each other every year; others do not, with the male leaving once mating has occurred.
