The phylogeny of squamate reptiles (lizards, snakes, and amphisbaenians) inferred from nine nuclear protein-coding genes.
Iguania should not be viewed as representing a primitive state of squamate evolution but rather a specialized and successful clade combining lingual prehension, dependence on visual cues, and ambush foraging mode, and which feeds mainly on prey avoided by other squamates. Expand
Early evolution of the venom system in lizards and snakes
Demonstration that the snakes, iguanians and anguimorphs form a single clade provides overwhelming support for a single, early origin of the venom system in lizards and snakes. Expand
The phylogeny and classification of caenophidian snakes inferred from seven nuclear protein-coding genes.
The phylogeny indicates that, ancestrally, caenophidian snakes are Asian and nocturnal in origin, although living species occur on nearly all continents and are ecologically diverse. Expand
Evolution of an Arsenal
Investigation of the timing of toxin recruitment events across the entire advanced snake radiation indicates that the evolution of advanced venom systems in three front-fanged lineages is associated with recruitment of new toxin types or explosive diversification of existing toxin types. Expand
A taxonomic framework for typhlopid snakes from the Caribbean and other regions (Reptilia, Squamata)
Scolecophidians are the most ancient (deeply-branching) group of living snakes and their relationships track plate tectonics better than any other vertebrate group. Expand
The molecular evolutionary tree of lizards, snakes, and amphisbaenians.
Molecular phylogenies have made it possible to draw a detailed evolutionary history of venom among advanced snakes (Caenophidia), a key functional innovation underlying their radiation (approximately 2500 sp.). Expand
Origin of tropical American burrowing reptiles by transatlantic rafting
It is shown with molecular evidence that oceanic dispersal—on floating islands—played a more prominent role, and that am Memphisbaenians crossed the Atlantic Ocean in the Eocene (40 Myr ago) resulting in a tropical American radiation representing one-half of all known amphisbaenian species. Expand
Phylogenetic relationships of xenodontine snakes inferred from 12S and 16S ribosomal RNA sequences.
The results suggest that some morphological and ecological traits concerning maxillary dentition, macrohabitat use, and foraging strategy have appeared multiple times during the evolution of xenodontine snakes. Expand

It is shown that DNA sequence evidence does not support a close relationship between snakes and monitor lizards, and thus supports a terrestrial origin of snakes. Expand
Dissecting the major African snake radiation: a molecular phylogeny of the Lamprophiidae Fitzinger (Serpentes, Caenophidia)
Molecular data do not support the traditional placement of Micrelaps within the Atractaspidinae, but its phylogenetic position requires additional molecular data and they are both treated as Elapoidea incertae sedis. Expand
