Quintessence of Dust

Quintessence of Dust explores science, society, and human nature, focusing on genetics, development, evolution, neuroscience, systems biology, and topics related to scientific literacy. I occasionally discuss intelligent design, creationism, science denial, and other political/social influences on scientific literacy. Additional topics: philosophy, baseball, scientific culture, and Shakespeare. My main theme is scientific explanation.

Disputes and controversies in science are always a good thing. They're fun to read about (and to write about), and they're bellwethers of the health of the enterprise. Moreover, they tend to stimulate thought and experimentation. Whether scientists are bickering about evo-devo, or about stem cells in cancer, or about prebiotic chemistry, and whether or not the climate is genial or hostile, the result is valuable.

Chapter 9 is called "Ends and Odds." Chapter 10 is "Beyond the Reach of Chance." Between them, they advance a straw man so idiotic that I wonder whether Meyer will be able to reclaim any significant intellectual integrity in the chapters that follow. I've already noted that this is not a book of science or of serious scholarship. Now it seems that it doesn't even merit the distinction of popular science or pop philosophy.

Consider these not-so-random samples from the animal world: a cockroach, a zebrafish, a mouse. What do these creatures have in common? Left to right: American cockroach (Periplaneta americana), zebrafish (Danio rerio), house mouse (Mus musculus). Cockroach image from Wikimedia Commons, zebrafish and mouse from Wellcome Images. Well, they're all animals and that means they're all eukaryotes, for example. They all have DNA-based genomes.

About 2 months ago, I finished a series on Michael Behe's latest book, The Edge of Evolution. I concluded that it was a terrible book, displaying significant errors of both fact and judgment. The book's main argument is a population genetics argument, and Behe seems to have little knowledge or understanding of that difficult subject.

Charles Darwin collected all sorts of cool stuff (like a vampire bat, caught while feeding on his horse) on his journey aboard the Beagle, and it has to be said that he understood little of it until after he got back. The finches that bear his name were identified as such by someone else, and his own bird collections from the Galapagos were nearly worthless due to the fact that he hadn't bothered to label specimens as to their place of origin.
