Social structures form through group dynamics, not trait selection
From her work studying social insects, Arizona State University biologist Jennifer Fewell believes that these remarkable animals suggest a an alternate cause behind the development of complex societies. In a viewpoint essay in the September 26 issue of the journal Science, Fewell argues that complex social structures like those seen in social insect communities can arise initially from the nature of group interactions -- the inherent dynamics of networks.
The ability of certain animals to form complex social systems -- particularly humans and social insects like bees, ants and termites -- is considered by many biologists to be one of the pinnacles of biological adaptation and complexity. Social organization allows organisms to share labor, to specialize in tasks and to coordinate efforts. Through organization, social animals accomplish remarkable things - they build colonies supporting millions of individuals, maintain multi-layered social systems, manage complex farming and food production systems, and build elaborate designs and constructions, from giant self-cooling termite towers to skyscrapers.
