University of Tennessee professor Stan Guffey is considering legal action against Ray Comfort, the evangelist who has spearheaded a nationwide drive to distribute free copies of his doctored version of Charles Darwin’s “The Origin of the Species” on college campuses, including at the University of Minnesota. Comfort, who denies evolutionary biology, published his own edition of Darwin’s treatise so he could annotate it with fundamentalist Christian criticism. But it turns out that Comfort’s introduction apparently contains whole passages from Guffney’s biography of Darwin — without citing Guffney. And here’s a twist: Guffney is an ardent opponent of Comfort.
