Abstract
The debate in Metaphysics of Science concerning the interaction between metaphysics and science has been mainly approached from the perspective of the scientificdiscipline of physics. In this paper, I address this debate from a different framework, namely that of biology. I pay attention to the recent characterization of Metaphysics of Biology and the different forms in which philosophers use metaphysics when addressing conceptual biological problems. In doing so, I argue that two main lessons can be obtained that can serve to enrich the debate in Metaphysics of Science: i) that the interaction between metaphysics and science seems to be more complex than generally considered; and ii) that the type of metaphysics that is interacting with science when characterizing the ontological status of the world is neither the a priori nor the naturalized one, but a different form of metaphysics that will be labelled here as applied metaphysics.
