It was this apparent tension between science and the more traditional theological account of the origin of the human race that I attempted to resolve in an article which I published in 2011.16  Building on some work by Josephite priest Andrew Alexander,17 and applying the adage, “When faced with a contradiction, make a distinction,” I suggested this possible account of the origin of the human race: Evolution of a population of primates sufficiently large to carry the genetic diversity in question and with cognitive development sufficient to allow the infusion of a rational soul. Transformation of two of those primates into rational and, therefore, “fully human” beings by infusion of a created rational soul18 without destruction of their reproductive compatibility with the primate population out of which they were selected. At that point, there would have existed both “fully human” (i.e., rational) beings and “merely biologically human” beings.19 Interbreeding between the fully human beings and their merely biologically human neighbors. Creation of rational souls for each of the descendants of every fully human being. (Strictly, “for many of the descendants” is all that is necessary.)
