God, Evolution, and the Body of Adam

Catholic evolutionists have proposed to reconcile evolutionary anthropogenesis with Catholic doctrine by suggesting that a created soul could be infused into a body produced (in part, if not wholly) by evolution from an animal body. Could such an infusion yield not just a Platonic composite but a being with the unity of substance required by a Thomistic philosophy of nature? How could such a soul be the form of the body into which it was infused?This paper suggests that animals seem to have sense-powers with a level of complexity, if not sufficient to underlie the abstraction of concepts in a being that also has a rational soul, then at least nearly so. The burden of proof lies rather on those who think that evolutionary development of such powers is not possible.In its final section, the paper argues that the existence of Eve as a second, and the only additional, initial rational being does not create special problems for the view here articulated.
