Classification and phylogeny
Note: this page has a large transclusion size. To see the cladogram, which demonstrates use of collapible clades, use the edit and preview.


 * Lacertilia, the lizards
 * Serpentes, the snakes (see also Ophidia)
 * Amphisbaenia, the worm lizards

Of these, the lizards form a paraphyletic group, since "lizards" excludes the subclades of snakes and amphisbaenians. Studies of squamate relationships using molecular biology have found several distinct lineages, though the specific details of their interrelationships vary from one study to the next. One example of a modern classification of the squamates is

All recent molecular studies suggest that several groups form a venom clade, which encompasses a majority (nearly 60%) of squamate species. Named Toxicofera, it combines the groups Serpentes (snakes), Iguania (agamids, chameleons, iguanids, etc.), and Anguimorpha (monitor lizards, Gila monster, glass lizards, etc.).
