I was rereading Dawkins's The Greatest Show On Earth a couple of weeks ago, and I've always found interesting his discussion of species classifications, particularly with regard to class designations. He points out the arbitrariness of the class distinction between birds and reptiles, making specific reference to the fact that lizards and birds are far more closely related by DNA than are, for example, lizards and turtles, yet lizards and turtles both occupy the reptilian class, while birds do not.
