A major challenge for evolutionary biology is explaining altruism, particularly when it involves death of one party and occurs across species. Chimeric fruiting bodies of Dictyostelium discoideum and Dictyostelium purpureum develop from formerly independent amoebae, and some die to help others. Here we examine co-aggregation between D. discoideum and D. purpureum, determine its frequency and which party benefits, and the extent of fair play in contribution to the altruistic caste.
