The self-sacrifice of sterile workers in ant colonies has been particularly difficult for evolutionary biologists to explain. This title presents an overview of the scientific knowledge about social evolution in ants. It shows how studies on ants have contributed to an understanding of many fundamental topics in behavioral ecology.

As the study of cooperative breeding systems expands, a number of key species form the examples that underpin our general understanding. The ostrich is increasingly becoming such a textbook species, on the basis of the results obtained in Brian Bertram's study of vigilance and egg discrimination in this extraordinary bird. Here Bertram presents new
