John Gray's awful review of Dawkins's book

John Gray has a review of Richard Dawkins's An Appetite For Wonder at New Republic here. I review Gray's awful review here.
Gray begins with a quotation from Dawkins that, suggests Gray, exhibits several of Dawkins's 'traits' in his 'campaign against religion'. Here's what Gray quotes from Dawkins:
Intelligent life on a planet comes of an age when it first works out the reason for its own existence. If superior creatures from space ever visit earth, the first question they will ask, in order to assess the level of our civilisation, is: “Have they discovered evolution yet?” Living organisms had existed on earth, without ever knowing why, for over three thousand million years before the truth finally dawned on one of them. His name was Charles Darwin.
Gray claims this passage reveals three things:
1. Gray says: 'There is his equation of superiority with cleverness: the visiting aliens are more advanced creatures than humans because they are smarter and know more than humans do.'
