What is the use of living in a group?

An old and well-known proverb tells us that unity is strength. This principle is been exploited not only with the symbiosis of different kinds, but also through alliances and cohabitation between members of the same species. These, rather than living isolated, can meet in groups with multiple advantages: in a group, predators can encircle the prey, the prey in the flock can better defend themselves from predators; together can carry out activities otherwise impossible, for example, the ants may build huge anthills only through cooperation.
The strategy group is very old and, as in the case of symbiosis, may be so extreme as leading to formation of a single body; it is apparently successful in the first multicellular beings, descendants from colonies of unicellular organisms, so closely associated with their group that they cannot live without it.
