As Jerry Coyne has alerted us, there is a free evolutionary biology textbook available on Kindle — grab it while you can (if you don’t have a kindle, just put the free Kindle app on your computer).
I haven’t had a chance to look the book over myself. Eugene Koonin is a respected name, but books that claim to establish a “Fundamentally New Evolutionary Synthesis” put me off a bit. Other stuff in the summary sounds interesting, though, just downplay the grandiose claims a bit when reading it.
