Signature in the Cell is an awesome book. One of the things I like about the book is how Stephen C. Meyer explains how DNA works as digital code and gives a lot of background about information theory as well as a history of how the DNA was discovered and studied! There is an accompanying website that includes links to debates in which Dr. Meyer defends his book and research. The site also includes a really nice video showing how DNA is read and used by cells in Animation. I love this stuff! It really is a lot like how computers encode information. Check out the website.
