Cooperation Among Animals - An Evolutionary Perspective. Oxford Series in Ecology and Evolution (Electronic book text)

This study outlines four different categories of co-operation among animals - reciprocal altruism, kinship, group-selected co-operation, and by-product mutualism - and ties them together in a single framework called the "Co-operator's Dilemma." Studies on co-operation in insects, fish, birds and mammals are then reviewed, each example being tied back to the theoretical framework developed early on when the data allows. Future experiments designed to further elucidate a particular type of co-operation are provided throughout the book.
