Thesis (Ph.D.)--Stanford University, 1999.

The transition from single organisms competing with one another to colonies of organisms that cooperate, has occurred many times throughout evolution. There are more than 23 separate instances of transition from uni- to multicellularity. Eusociality has arisen more than 11 times in the Hymenoptera, once in the termites, and at least twice in mammals. If one also takes into account lower levels of cooperation, then this count will increase many-fold. This thesis includes several approaches to understanding the mechanisms in the transition. It centers around the importance of sharing information among individuals in the colony, and the evolution of cooperation. Included are: a model for understanding the behavior of an ant colony through the behavior of the single ants; a model for evolution of coexistence of cooperation and defection when defection is favored; a model showing the advantage of sharing information in a collective; models of adoption, when this trait is culturally transmitted.
