Cooperation and Conflict in Social Amoeba

Abstract: Societies require cooperation, where individuals work together to accomplish what they cannot achieve by themselves. But how can societies survive when what is best for the group entails sacrifices on the part of individuals? I will be describing our research using a model organism, the cellular slime mould (aka social amoeba) Dictyostelium discoideum - an unusual organism that alternates between a solitary, single-celled existence and group living as an integrated, multicellular organism. The transformation to the multicellular state requires that some cells give up their lives, an act that likely benefits the rest, and prior work has shown that not all strains are equally likely to make this sacrifice. I will describe our recent work that explores how this organism can maintain its altruistic behaviours in the face of genetic and evolutionary opportunities to behave more selfishly.
