SQUAMATA (PART) — Other Lizards
The taxonomy used by the KHA reflects our understanding of evolutionary history. It is well-established that the traditional group "lizards" is not natural. And that snakes are a derived group of lizards that share a more recent common ancestor with some groups of lizards than they do with others. To reconcile this well-supported hypothesis, the KHA has opted to list all snakes and "other lizards" under Squamata. While this arrangement doesn't appear in most popular books, the continued traditional recognition of snakes with an equal but separate catchall "lizards" is untenable.
