Different components contribute to the evolution of advanced sociality. These include the existence of non‐depreciable resources, ecological constraints, relatedness patterns, direct fitness effects of group living, demography and phylogenetic inertia. Several of these components are usually responsible for the origin and stability of highly organized groups in which conspecifics cooperate in reproduction. Therefore, all these levels should be considered when we aim to understand such complex social patterns. This is usually difficult for practical reasons. In cooperatively breeding cichlids, however, it is possible to study the importance of these components with observational and experimental approaches. With help of this paradigm I aim to illustrate the potential significance of these extrinsic and intrinsic causes of social evolution, and their functional relationships.
