Plantinga on Science and Religion

"The point is that a mutation accruing to an organism is random, just as neither the organism nor its environment contains the mechanism or process or organ that causes adaptive mutations to occur.  But clearly a mutation could be both random in that sense, and also intended (and indeed caused) by God.  Hence, the randomness involved in Darwinism does not imply that the process is not divinely guided.  The fact (if it is a fact) that human beings have come to be by way of natural selection operating on random genetic mutation is not at all incompatible with their having been designed by God and created in his image.  Therefore Darwinism is entirely compatible with God's guiding, orchestrating, and overseeing the whole process.  Indeed it's perfectly compatible with the idea that God causes the random genetic mutations that are winnowed by natural selection.  Maybe all of them.  Maybe just some.  Those who claim that evolution shows that humankind or other living things have not been designed apparently confuse the naturalistic gloss on the scientific theory with the theory itself.  The claim that evolution demonstrates that human beings and other living creatures have not—contrary to appearances—been designed, is not a part of or a consequence of the scientific theory as such, but a metaphysical or theological add-on.  Naturalism implies of course that we human beings have not been designed and created in God's image, because it implies that there is no such person as God.  But evolutionary science by itself does not carry this implication.  Naturalism and evolutionary theory together imply the denial of divine design.  But evolutionary theory by itself doesn't have that implication.  It is only evolutionary science combined with naturalism that implies this denial.  Since naturalism all by itself has this implication, it’s no surprise that when you conjoin it with science—or as far as that goes anything else: the complete works of William E. McGonagall, poet and tragedian for example, or the Farmer's Almanac, or the Apostle's Creed—the conjunction will also have this implication [audience laughter]."
