Science is intended to discover the “is”, not the “ought;” facts, not values. Science can’t tell us whether an action is moral; it can only provide evidence to help inform moral decisions. For instance, some people who believe abortion is immoral reject birth control methods that prevent implantation of a… read more "Tribalism and Medical Ethics"
Doves, Diplomats, and Diabetes
In the past I have criticized evolutionary medicine for its tendency to rely on unverifiable “Just-So Stories,” but a new book has helped me appreciate what the best kind of evolutionary thinking can contribute to our understanding of medicine. Doves, Diplomats, and Diabetes: A Darwinian Interpretation of Type 2 Diabetes and Related… read more "Doves, Diplomats, and Diabetes"
Gender Differences and Why They Don’t Matter So Much
Several incidents have recently created divisions within the skeptical community. The latest one was over a casual comment Michael Shermer made in an online talk show. He was asked why the gender split in atheism was not 50/50, “as it should be.” He said he thought it probably was 50/50, and suggested… read more "Gender Differences and Why They Don’t Matter So Much"
Worms, Germs, and Dirt: What Can They Teach Us About Allergies and Autoimmune Diseases?
Humans evolved in an environment where they were exposed to animals, dirt, and a variety of pathogens and parasites. Our immune systems evolved to cope with that environment. Now most of us live in a different environment, with safe drinking water, flush toilets, food inspection, immunizations, and public sanitation. This… read more "Worms, Germs, and Dirt: What Can They Teach Us About Allergies and Autoimmune Diseases?"
Thumbthing Worth Reading
I intended to read Sam Kean’s new book The Violinist’s Thumb: And Other Lost Tales of Love, War, and Genius as Written by our Genetic Code just for fun. I was expecting a miscellany of trivia loosely gathered around the theme of DNA. But I found something much more worthwhile that I… read more "Thumbthing Worth Reading"
Learning from Animals: Evolutionary Medicine with a Twist
In 2005, cardiologist Barbara Natterson-Horowitz was called to the zoo to examine a non-human patient, an emperor tamarin with heart failure. She was surprised when the veterinarian told her not to look her patient in the eyes because eye contact could cause capture myopathy. In this condition, when an animal… read more "Learning from Animals: Evolutionary Medicine with a Twist"
Do We Need “Evolutionary Medicine”?
Three years ago I wrote an article critical of “evolutionary medicine” as it was presented in a new book. Recently a correspondent asked me if I thought another book, Why We Get Sick: The New Science of Darwinian Medicine, by Randolph M. Nesse, MD and George C. Williams, PhD, was a more… read more "Do We Need “Evolutionary Medicine”?"

Evolutionary Medicine
I have been asked to review a pre-publication proof of a book that will be published in May 2009: Evolution Rx: A Physician’s Guide to Harnessing Our Innate Capacity for Health and Healing by William Meller, MD. It offers “a primal yet radical new view of why we act and… read more "Evolutionary Medicine"
Science & Morality
Review of Render Unto Darwin: Philosophical Aspects of the Christian Right’s Crusade against Science, by James H. Fetzer. THIS BOOK STARTS OUT WELL BUT ENDS BADLY. It is an awkward compilation of three different subjects: evolution science, morality, and politics. The science is well done. Fetzer begins by explaining the difference between science… read more "Science & Morality"
