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.

The chapter is called "The Double Helix," and there's not much to say about it. Meyer provides a fairly standard narrative of the discoveries that led to Watson and Crick and molecular biology. Anyone who's read The Eighth Day of Creation, along with a decent genetics textbook and/or a memoir by one of the principals (What Mad Pursuit by Francis Crick is a personal favorite) will already know everything here. Two observations.

The chapter is called "The Evolution of a Mystery and Why It Matters." It's interesting and engaging, and I enjoyed reading it. The "mystery" in question is first described on page 35: Continue reading...

The chapter is called "DNA, Darwin, and the Appearance of Design." It's a poor start. Meyer sketches some key themes of the rest of the book in this sloppy chapter. Here are those themes (in my words) and some comments. 1. DNA stores information, using a code that is similar to that of a computer. We know a lot about how that works. 2. Life gives the appearance of design. No one disputes that.

There's not much point in "reviewing" a prologue, so let's start instead with some impressions gleaned from reading the prologue and the first chapter while leafing through the rest of the book. 1. This is clearly a pop-science book and not a serious work of scholarship. That's not an insult, just an observation. Continue reading...

Interestingly, Meyer's book is getting a lot of attention right now. At the Jesus Creed, the excellent RJS is also blogging through the book. At Biologos, a guest piece by Francisco Ayala focuses mostly on theological issues. (I like Ayala a lot. I dislike his post a lot.) The ASA has finally decided to establish some blogs, one of which will host discussions of books. The first book under consideration is Signature in the Cell.

So Stephen Meyer of the Discovery Institute, a founder of the ID movement, wrote a book called Signature in the Cell: DNA and the Evidence for Intelligent Design. It came out last summer, and I ignored it. I ignored it because it didn't seem interesting or important or new, and there's always something interesting and important and new to read. (I recently finished The Road.

The Blind Watchmaker is a superb book by a masterful science writer. It's not just a book about evolution, or even about how evolution works. It's a book about how evolution explains design, and more specifically how natural selection accounts for design. As I wrote before, I consider chapter 3 to be the most important chapter of the book.

Back in September I wrote about the silly preoccupation on the part of various anti-evolutionists with the so-called Weasel program, a simple exercise created more than 20 years ago by Richard Dawkins to illustrate the efficacy of cumulative selection in evolutionary scenarios.
