A few years later, creationist biologists Carl Krekeler and William Bloom, who taught creationist biology at the Lutheran Church's Valparaiso University in Indiana, left after concluding that a literal interpretation of Genesis was not supported by any of the available scientific evidence. Krekeler concluded, "The documentation, not only of changes within a lineage such as horses, but of transitions between the classes of vertebrates-- particularly the details of the transition between reptiles and mammals--forced me to abandon thinking of evolution as occurring only within 'kinds'. " (cited in Numbers, 1992, p. 302) Krekeler also criticized the creationist movement for the "dozens of places where half-truths are spoken, where quotations supporting the authors' views are taken from the context of books representing contrary views, and where there is misrepresentation." (cited in Numbers, 1992, p. 303) The two became theistic evolutionists, and later wrote a biology textbook which accepted evolutionary theory.
Perhaps as a result of these defections, the creationist movement no longer finances or carries out any field research of any sort. Its sole method of "scientific research" consists of combing through the published works of evolutionary mechanism theorists to look for quotations which can be pulled out of context and used to bolster creationist beliefs.
I wonder if the creationists will lump these guys into the atheist category, too?
