List of Serpentes families - Wikipedia
There are two infraorders of living snakes: Alethinophidia and Scolecophidia. This separation is based primarily on morphological characteristics between family groups; however, more recently, the comparison of mitochondrial DNA has played its part.
Snake phylogeny - REPTILE DATABASE
Phylogenetic tree of snakes based on mitochondrial 12s and 16s rRNA sequence data (8 18 aligned sites). An iguanid lizard (Sceloporus undtdatus) was included, and the tree was rooted with a tuatara (Sphenodon pzmtatzu).
