Abstract

I argue that biological fitness sometimes depends on imprecise probabilities. I give a new argument that some outcomes are without objective probability, and argue that organisms encountering environments might sometimes be outcomes of this kind. I argue that since fitness depends on relationships between traits and environments, this means that fitness can depend on imprecise probabilities, and can be defined by an interval between maximum and minimum precise fitnesses. One trait is fitter than another when its minimum fitness is greater than the other’s maximum fitness or when, in some conditions, the first trait has greater fitness in every environment.
