Query: Don't know much about Davis

The moment I saw this book in our local bookstore, I quickly grabbed it. The title is very eye-catching since I'm very interested about the sciences, and Geography is one fascinating subject. The book is written in simple terms and easy to understand. What I didn't like about the book is that it's explicitly very biased against the creation theory. On the earlier pages, the author clearly stated that science is dynamic which I or presumably anyone will understand that when it comes to the sciences nothing is certain. Yet the author appears to be preaching the THEORY of evolution as a fact. I thought books like this calls for unbiased and unpartial content. So I scanned the back pages looking for his credentials. And I found my evidence, "don't know much about Davis".
