Evolvability, Dispositions, and Intrinsicality

Love, Alan C. (2002) Evolvability, Dispositions, and Intrinsicality.

Abstract

In this paper I examine a dispositional property that has been receiving increased attention in biology, evolvability. First, I identify three compatible but distinct investigative approaches, distinguish two interpretations of evolvability, and treat the difference between dispositions of individuals versus populations. Second, I explore the relevance of philosophical distinctions about dispositions for evolvability, isolating the assumption that dispositions are intrinsically located. In conclusion, I argue that some instances of evolvability cannot be understood as purely intrinsic to populations and suggest alternative strategies for resolving this difficulty.
