The Evolving Taxonomy of Progressive Creation

This essay is a critique of a version of progressive creation developed by Michael Chaberek, O. P. He holds that there are exceptions to evolutionary descent due to the supernatural production of “natural species,” taxa that allegedly do not have biological ancestry, are theologically identified with biblical kinds, and are metaphysically characterized by distinct substantial forms. Chaberek’s assertion that these natural species correspond “roughly” to the Linnaean taxa of biological families contradicts modern scientific conclusions regarding the continuity of evolutionary descent. To illustrate this conflict, I examine some of the extensive evidence for the evolutionary origins of families within the Feliformia sub-order. I conclude that Chaberek’s assertion of supernatural progressive creation is a God-of-the-gaps theology burdened by a defensive stance with respect to scientific progress.
