Evolutionary Theory’s Welcome Crisis

EXETER – Those who believe that a supernatural being created the universe have never posed an intellectual challenge to evolutionary theory. But creationists, whether biblical fundamentalists or believers in “intelligent design,” do pose a threat to scientific thinking. Indeed, creationism’s insidious genius lies in its ability to reinvent evolution in its own image as a dogmatic belief system – and thus the antithesis of science.

The creationists are right about one thing: contrary to the impression given by much popular writing on the subject, the theory of evolution is in crisis. But this is a positive development, because it reflects the non-linear progress of scientific knowledge, characterized by what Thomas Kuhn described in his influential book The Structure of Scientific Revolutions as “paradigm shifts.”
