the cognitive powers of a good high school student. In such an environment (and if you doubt my appraisal, read some of the reviews below), it takes conscious intent to ignore manipulative appeals to the "argument from sociology" and attend to substance. For the record, Behe is not an "ID-iot." He is a sharp and thoughtful biologist who doesn't think evolution can work on its own. In this book he argues for common descent, but argues that naturalistic evolution is limitted. He thinks the mechanisms suggested for powering the massive creativity and innovation in nature could not come from mutations alone. His primary tool for advancing this argument is the evolution of the malaria bug, and of human immune defenses against it, over the past several thousand years. Behe shows that while microbes can and do evolve resistances to medicine, they generally do so by breaking down in some way, as does the human body. Touching briefly on the evolution of e coli and HIV, then on other critters, he makes the case that bugs that evolve rapidly, and through huge communities, demonstrate the limits to naturalistic evolution. The mathematical arguments he brings in to explain and support his more theoretical argument against the power of mutations, which some reviewers take issue with below, are not his main line of persuasion, nor, I admit, do they seem fully persuasive as developed here. This book is not about Irreducible Complexity (IC). Behe defends the concept, and his examples of it, briefly,
