The Greatest Show on Earth: The Evidence for Evolution

This book made me more appreciate the beauty of our Nature; how grande and elegant they are. Every species are connected by space (ecosystem) and time (evolution). Dawkins beautifully explains evolution in a way that you really respect the beauty of how nature works, truly the greatest show on earth.

One side note, Dawkins likes to oppose creationism, for me it does not really matter, but I think I can't recommend this to my hardcore creationism friends, as they might easily drop off the book.
