The notion of fitness has traditionally played two roles in evolutionary biology: As an ecological descriptor and as a mathematical predictor (Sober [2001]). The orthodox notion of fitness fails to account for the role of the notion as an ecological descriptor. The propensity interpretation of fitness (PIF) aims at explaining the reproductive success of organisms by relying on the notion of disposition. If successful, it can account for the organism-environment relation through the stimulus conditions for the disposition to reproduce successfully, hence fulfilling the role of ecological descriptor. In this paper I will show that the PIF fails to do so. In order to fulfill the role of ecological descriptor, a new approach is needed
