Abstract

This article engages Kojonen's discussion of scientific explanation. Kojonen claims the best way to conceptualize the relationship between evolutionary explanations and explanation by design is through the proximate-ultimate distinction and the levels metaphor. However, these are not robust explanatory models but examples of how one might differentiate ambiguous explananda contained in why-questions. Disambiguating explananda is a helpful tool for determining when a situation calls for further explanation; however, on this picture, that some further explanation is needed does not, as proponents of design arguments assume, specify design. The question of whether design is a good explanation at all hinges on what precisely we want explained.
