Physicalism per se can’t vindicate adaptationism [Darwinism] … Arguably, what determines which trait was selected-for is which laws governed the selection: given the laws, the counterfactuals follow; given the counterfactuals, you can distinguish a trait that isselected-for from a trait that isn’t. But physicalism isn’t committed to any particular inventory of laws; it says only that every causal intervention falls under some physical law or other. It follows from physicalism that if there is such a process as natural selection, it falls under physical laws (inter alia). But that says nothing at all about whether there is such a process. S the next time someone tells you that adaptationism is required by the ‘scientific world view’, we recommend that you bite his or her ankle. (p. 130)
