More interesting than expected, given the title. I was expecting either 'No' (if the Christian insists on a literal reading of Genesis), or 'Sure, why not?' otherwise. Turns out that even if one allows a metaphoric reading of the Creation story, there are still other issues to be considered. Everything from Evil to Morality to The Possibility of Intelligent Extraterrestrials brings up possible philosophical disagreements. All of which are given even-handed and broad coverage.
The one critique I have is that the final answer to the title question seems a little too conclusive, given the evidence presented. Admittedly his "Can a Darwinian be a Christian? Absolutely!", is followed by "Is it always easy for a Darwinian to be a Christian? No, but whoever said that the worthwhile things in life are easy?", but that "Absolutely!", (with an exclamation point even!), seems just a little too positive. The sticky issue (in my opinion), is monogenism (the idea that humans are descended from a unique pair - not supported by Darwinianism), which seems necessary for the Fall Of Humanity (and the whole concept of Original Sin), which is a fairly essential component of Christian theology. He admits it's an important issue, but doesn't seem to really resolve it.
All in all, I would recommend this book, even if you don't really care whether a Darwinian could be a Christian - it would still be an interesting, thought-provoking read.
