 Maclaurin and Sterelny’s approach is very suggestive but as we have seen its execution by biologists requires making good on using species richness augmented with information regarding phenotypic variation, ecology, development, and phylogeny into an empirical tractable hyperspace. The extent to which this can be done is unclear (Justus 2010; Morgan 2009). Their approach also presupposes a particular account of species as well.
