A specialist on social insects writes about the origins and implications of our own vast social organisation, and the ways in which our ethnic and national distinctions mirror those of other animals.

In this paradigm-shattering book, biologist Mark W. Moffett draws on findings in psychology, sociology and anthropology to explain the social adaptations that bind societies. He explores how the tension between identity and anonymity defines how societies develop, function, and fail. In the vein of Guns, Germs, and Steel and Sapiens, The Human Swarm reveals how mankind created sprawling civilizations of unrivalled complexity - and what it will take to sustain them.
