Sex ratios and social evolution

Group size in primates is strongly correlated with brain size, but exactly what makes larger groups more ‘socially complex’ than smaller groups is still poorly understood. Chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla) are among our closest living relatives and are excellent model species to investigate patterns of sociality and social complexity in primates, and to inform models of human social evolution. The aim of this paper is to propose new research frameworks, particularly the use of social network analysis, to examine how social structure differs in small, medium and large groups of chimpanzees and gorillas, to explore what makes larger groups more socially complex than smaller groups. Given a fission-fusion system is likely to have characterised hominins, a comparison of the social complexity involved in fission-fusion and more stable social systems is likely to provide important new insights into human social evolution

Conceptual Foundations

The article discusses the conceptual foundations of the development of the general sociological theory of J.G.Turner. These foundations are metatheoretical ideas, basic concepts and an analytical scheme. Turner began to develop a general sociological theory with a synthesis of metatheoretical ideas of social forces and social selection. He formulated a synthetic metatheoretical statement: social forces cause selection pressures on individuals and force them to change the patterns of their social organization and create new types of sociocultural formations to survive under these pressures. Turner systematized the basic concepts of his theorizing with the allocation of micro-, meso- and macro-levels of social reality. On this basis, he substantiated a simple conceptual scheme of social dynamics. According to this scheme, the forces of macrosocial dynamics of the population, production, distribution, regulation and reproduction cause social evolution. These forces force individual and corporate actors to structurally adapt their communities in altered circumstances. Such adaptation helps to overcome or avoid the disintegration consequences of these forces. The initial stage of Turner's general theorizing is a kind of audit, modification, modernization and systematization of the conceptual apparatus of sociology. The initial results obtained became the basis for the development of his conception of the dynamics of functional selection in the social world.
