Frank J. Sherwin III is a research associate, “Senior Lecturer” at, and “Science Writer” for the Institute for Creation Research, sometimes coauthoring with Brian Thomas for the ICR newsletter Acts and Facts. Apparently he has a master’s degree in zoology, which is not (apparently) quite sufficient to confer any authority on his rejection of virtually his whole area of expertise.
He has also published in Answers in Genesis’s house journal Answers, including “Louis Pasteur’s Views on Creation, Evolution, and the Genesis of Germs”, with Alan L. Gillen (which, one wonders, is supposed to show exactly what?) and “A Possible Function of Entamoeba histolytica in the Creation Model”, which contains absolutely no research (“the Scriptures teach” doesn’t count) but plenty of conjecturing concerning a micro-organism before and after the Fall. Sherwin is, however, perhaps most famous for taking the Cambrian explosion to be one of the “four irrefutable arguments” against evolution – not that he ever pauses to consider what biologists actually have to say about it.
According to his sister Elisabeth, Sherwin is a creationist because he is “irritated by the arrogance of evolutionists who claim to have all the answers,” which sounds like a pretty lame reason; also, “the world view of a person who thinks they came from bacteria is likely to be substantially different from the world view of someone who thinks they were created in God’s image,” which is not a particularly well-considered reason either.
Diagnosis: Pretty much your standard fare among creationists. Because of Despite the complete absence of actual research (or critical thinking) efforts, Sherwin nevertheless remains a figure of authority in the creationist movement.
