Herpetology is Paraphyletic

Another great comic by xkcd this time explaining how the study of Reptiles and Amphibians in one group, known as Herpetology, is in fact an unnatural grouping and so it is paraphyletic. Make sure you visit their site itself so you can see the comment when you mouse over the comic, lets just say that there is a problem that Aves is a Class while Dinosauria is a Superorder (ironically this is something I covered in the labs I taught this week).
