Matt Ridley is a clear concise author who doesn't have Richard Dawkin's habit of rambling on and on and on just to make sure the reader understands. As a consequence of this all of his works are wonderful to read, and are accessible to all, from university biology professors, to students, to laymen who are just hungry for knowledge. Genomes is no exception to this rule, with the book laid out clearly and ingeniously and even a helpful glossary of terms in the preface. Overall a brilliant book well worth reading. Take a look at The Origins Of Virtue for another top class example of his work.
