A common type of mutation is an error in replication or meiosis leading to a change in base. Mutation is one of five mechanisms driving evolution. So I was thinking: how can theistic evolutionists reconcile the notion of a perfect god who works through errors? They may respond and say that the end justifies the mean, but that wouldn’t answer the question. Why? Because most of these errors are harmful. Enough of them can lead to a dead end, which, in turn, leads to another question: why create or allow the existence of a specie that leads no where? In other words, if the end justifies the mean, why is the end a dead end sometimes? Imperfect evolution and the notion of a perfect god are incompatible unless one believes in a god that’s the raison d’être. Of course, that concept is unsatisfying to a person of faith, but that’s a separate matter.
