Living things are organized in a hierarchy of levels. Genes group together in cells, cells group together in organisms, and organisms group together in societies. Even different species form mutualistic partnerships. Throughout the history of life, previously independent units have formed groups that, in time, have come to resemble individuals in their own right. Evolutionary biologists term such events "the major transitions." The process common to them all is social evolution. Each transition occurs only if natural selection favors one unit joining with another in a new kind of group. This...

Biologists since Darwin have been intrigued and confounded by the complex issues involved in the evolution and ecology of the social behavior of insects. The self-sacrifice of sterile workers in ant colonies has been particularly difficult for evolutionary biologists to explain. In this important new book, Andrew Bourke and Nigel Franks not only present a detailed overview of the current state of scientific knowledge about social evolution in ants, but also show how studies on ants have contributed to an understanding of many fundamental topics in behavioral ecology and evolutionary...
