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.
Formation of groups: Groups could consist of parent-offspring groups or unrelated groups (in situations where cooperation is beneficial) living in a structured nest. Pre-adaptations: Pre-adaptations for social living, such as progressive provisioning, will push the group further toward eusociality. Mutations: Mutations will arise and be selected.
In ethology, fission–fusion society is one in which the size and composition of the social group change as time passes and animals move throughout the environment; animals merge into a group (fusion)—e.g. sleeping in one place—or split (fission)—e.g. foraging in small groups during the day. For species that live in fission–fusion ...
Group living affords colony members defense against enemies, specifically predators, parasites, and competitors, and allows them to gain advantage from superior foraging methods. [7] The importance of ecology in the evolution of eusociality is supported by evidence such as experimentally induced reproductive division of labor, for example when ...
In the late 1900s, some early research in animal cooperation focused on the benefits of group-living. While living in a group produces costs in the form of increased frequency of predator attacks and greater mating competition, some animals find that the benefits outweigh the costs. Animals that practice group-living often benefit from ...
In this initial stage, a single female individual or small group of female individuals, often called the foundress(es), queen(s) (and kings for termites) or primary reproductive(s), establish a new colony. The foundresses build a basic nest structure and begin to lay eggs.
Collective animal behaviour is a form of social behavior involving the coordinated behavior of large groups of similar animals as well as emergent properties of these groups. This can include the costs and benefits of group membership, the transfer of information, decision-making process, locomotion and synchronization of the group.
This system is used in many unrelated animals: ants, bees, and wasps, termites, naked mole-rat, Damaraland mole-rat, Synalpheus regalis shrimp, certain beetles, some gall thrips and some aphids. [191] Oxygenate blood came about in unrelated animals groups: vertebrates use iron and crustaceans and many mollusks use copper . [192]
