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.

Here I'm continuing my discussion of the Signature in the Cell book-signing event at Biola University on 14 May. You'll want to read Parts I and II before reading on. My second question to Steve Meyer was the one question I most wanted to ask him, both out of personal curiosity and because I thought the answer would help demystify many of his claims. The exchange that resulted was memorable – on that, everyone seems to agree.

The chapter is called "Of Clues to Causes" and it's about scientific explanation. That's an interesting and important topic, one that opponents of evolutionary theory rarely understand. Meyer's summary is predictably fluffy but not inaccurate. Those seeking an introduction to philosophical questions pertaining to scientific explanation should look elsewhere, since Meyer says little in the 22-page chapter.

Meyer's basic idea in chapters 4 and 5 is reasonably coherent. But I find further evidence in both chapters that Meyer is careless and underinformed on the subjects he addresses. (I explained before why I think this matters. If you think I'm not being nice enough to Meyer, consider providing me with the Rules of Engagement that apply when criticizing culture warriors who are proposing world-shifting new ideas.)

Chapter 4 is called "Signature in the Cell." It's an important chapter for two reasons. First, along with chapter 5 ("The Molecular Labyrinth") it lays out Meyer's central question by pointing to the specific features of cellular information systems in need of explanation. Second, it exemplifies an aspect of ID thought that I want to highlight. I'll discuss these two themes here, then add some further critiques in a second post.

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.
