Yesterday I dropped by my local bookstore and had a look at The Greatest Show on Earth: The Evidence for Evolution
My first impression of it is that it is excellent. First, aesthetically: The cover of the book is beautiful, and there are numerous color photo inserts throughout the book that illustrate embryological development, fossils, and so on.
Dawkins takes a couple of chapters expounding upon transitional fossils, one on plant and animal transitionals, and another on human transitionals. He has really taken pains to correct common misconceptions about evolution, and he often corrects the same misconception multiple times so as to make sure that the reader fully understands why monkeys still exist, for instance.
He also does an excellent job of rebutting the old 'common design' claim people make in response to evolution. Remarkably, his answer to this is nearly identical to mine.
From now on, creationists are without excuse for being ignorant about Evolution. Every time a creationist comes to my blog to challenge me, I'm going to send them to this post, which will give them directions for becoming educated about evolution. If they won't listen to the efforts of world famous biologists to educate them, then I cannot expect that they will listen to my efforts to educate them on evolution or that they will be receptive to them. So, if you are a creationist, or someone genuinely curious about evolution, here is what I recommend for you:
1. Read The Greatest Show on Earth: The Evidence for Evolution
2. Check out an Index to Creationist Claims, which thoroughly rebuts just about every creationist argument there is. Search Talk.Origins to find the answers you need to the questions you have.
3. Read Why Evolution Is True
It's a little more in-depth, provides even more evidence for Evolution than Dawkins, and assumes the reader has at least a little knowledge of evolution.
4. Read the 29 Evidences for MacroEvolution. This is much shorter than any book you'll read, but it is fairly in depth and it lays out just about all the evidence (or all the main lines of evidence) for evolution that exists.
