Forber and Smead (2014) analyze how increasing the fitness benefits associated with prosocial behavior can increase the fitness of spiteful individuals relative to their prosocial counterparts, so that selection favors spite over prosociality. This poses a problem for the evolution of prosocial behavior: as the benefits of prosocial behavior increase, it becomes more likely that spite, not prosocial behavior, will evolve in any given population. In this paper, I develop two game-theoretic models which, taken together, illustrate how synergistic costs and benefits may provide partial solutions to Forber and Smead’s paradox.

“…A article by Ventura (2019) likewise analyzed how the addition of synergistic effects to Forber and Smead's model can provide a partial solution to the evolutionary paradox. However, Ventura's definition of synergism differs from mine, with the result that our analyses and proposed solutions to the paradox are quite different.…”

Inclusive Fitness and Kin Selection

The biological world is full of phenomena that seem to run counter to Darwin's insight that natural selection can lead to the appearance of design. For instance, why do organisms in some species divide reproductive labor? The existence of non-reproducing organisms in such 'eusocial' species looks to be at odds with an evolutionary theory which posits traits exist because they help organisms survive and reproduce. What is the evolutionary advantage of an insect being distasteful to its predators? The distastefulness appears designed to deter predators, but can only affect the predator's actions when the insect is eaten; it is hard to see how such a trait could be passed on. This Element will cover the shared foundations of evolutionary explanations for these and other seemingly puzzling phenomena, focusing on the concepts of inclusive fitness and kin selection.
