The Tangled Bank is now officially out; I'm getting word back from readers that it's actually showing up from Amazon. If you're curious about it, here are a couple ways to find out more. 1. I've set up pages on my web site where you can download the introduction, look at some of Carl Buell's artwork for the book, read reviews, and get contact information if you're a teacher interested in a desk copy. 2. The New York Academy of Sciences has published an excerpt in the new issue of their magazine. It's about the evolution of the eye, and you can read it online here. 3. Discover has another excerpt, about coevolution, in their November issue. The print issue is out now, and it should be posted online some time soon.
