Randy Guliuzza has made some controversial claims regarding the cause and nature of adaptation of organisms to their environment. Specifically, he claims that natural selection does not exist, that the environment is never the cause in the process of adaptation, and that organisms' ability to self-adjust is the cause of speciation. We examine Guliuzza's claims in four areas: (1) consistent and correct use of terminology, (2) logical coherence, (3) scientific accuracy, and (4) theological faithfulness. We find that Guliuzza's claims fail in each one of these categories. Guliuzza's central claims are mere rhetoric and do not stand up to rational scrutiny. Moreover, Guliuzza's view implicitly denies the omnipotence and sovereignty of God by restricting God's design and power to organisms. We then consider how to discuss natural selection and adaptation properly, by applying careful scientific reasoning and correct terminology. We find that natural selection is very real and scientifically observable. And we find that adaptation of organisms always involves an environmental causal factor.
