Group living
In ethology and evolutionary biology, group living is defined as individuals of the same species (conspecifics), maintaining spatial proximity with one another over time with mechanisms of social attraction. Solitary life in animals is considered to be the ancestral state of living; and group living has thus evolved independently in many species of animals. Therefore, species that form groups through social interaction will result in a group of individuals that gain an evolutionary advantage, such as increased protection against predators, access to potential mates, increased foraging efficiency and the access to social information.
Important aspects of group living include the frequency and type of social interactions (egoistic, cooperative, altruistic, revengeful) between individuals of a group (social life), the group size, and the organization of group members in the group. [citation needed]
Terminology of animal groups also varies among different taxonomic groups. Groups of sheep are termed herds, whilst groups of birds are referred to as colonies, or flocks.
Most studies on group living focus strictly on groups comprising a single species. However, many mixed-species groups commonly occur in nature. Examples of mixed-species groups include wildebeests forming groups with zebras, and different species of birds that form large foraging flocks.
Group living may sometimes be confused with collective animal behavior. Collective animal behavior is the study of how the interactions between individuals of a group give rise to group level patterns and how these patterns have evolved. Examples include the marching of locusts and flocks of migrating birds. Group living however focuses on the long-term social interactions between individuals of a group and how animals have evolved from solitary living.
It is extremely difficult to distinguish between solitary living and group living. Distinctions between the two are relatively artificial. This is because many species of animals who spend a majority of their life alone, at some point in their life, will join a group or engage in social behavior. Some examples of this happens during mating, parental care of their offspring, or even aggregations of conspecifics to an area to exploit resources of food or shelter. Therefore, multiple definitions of group living have been proposed. Differences in group living definitions vary dependent on the frequency and type of social interactions that members of a group display and the level of coordination and cohesion of group members. For example, Wilson (2000) defines a group as “any set of organisms, belonging to the same species, that remain together for a period of time while interacting with one another to a distinctly greater degree than with other conspecific organisms." This definition cannot be applied to situations such as moths drawn to a lamp, or when animals aggregate around a watering hole, as they are not exampling of a social aggregation. Most definitions however agree that a fundamental characteristic of group living is that individuals need to show spatial proximity over time to be considered a group. Therefore, the working definition of group living is where two or more individuals display a degree of spatial proximity over time, emphasizing the importance of mechanisms of social attraction to maintain these groups.
There have been multiple different hypotheses proposed to explain how group living evolved in animals. Research shows that grouping habits may differ between individuals, and this tendency to group can be inherited. Research also shows that grouping tendency depends heavily on the interaction of many genes, as well as experiences gained by an individual and the environmental conditions surrounding the individual. Other studies argue that the main driving force of the evolution of social grouping is phylogenetic inertia alongside ecological pressure. However, it is still unclear how exactly animals have evolved from the ancestral state of solitary life.
A key advantage to group living is the ability for individuals in a group to access information gained by other group members. This ability to share information can benefit many aspects of a group’s success, such as increased foraging efficiency and increased defenses against predators.
