Journal ArticleDOI

Evidence for an ancient adaptive episode of convergent molecular evolution.

TL;DR: Results indicate that nonneutral convergent molecular evolution in mitochondria can occur at a scale and intensity far beyond what has been documented previously, and they highlight the vulnerability of standard phylogenetic methods to the presence of non neutral convergent sequence evolution.
Journal ArticleDOI

Resolving the phylogeny of lizards and snakes (Squamata) with extensive sampling of genes and species

TL;DR: Higher-level squamate phylogeny is analysed with a molecular dataset of unprecedented size, including 161 squamate species for up to 44 nuclear genes each (33 717 base pairs), using both concatenated and species-tree methods for the first time, and it is found that dibamids and gekkotans are together the sister group to all other squamates.
Journal ArticleDOI

Integrated analyses resolve conflicts over squamate reptile phylogeny and reveal unexpected placements for fossil taxa.

TL;DR: It is found that integrating molecular, morphological, and paleontological data leads to surprising placements for two major fossil clades (Mosasauria and Polyglyphanodontia) and the importance of combining fossil and molecular information is demonstrated.
Journal ArticleDOI

Phylogeny of iguanian lizards inferred from 29 nuclear loci, and a comparison of concatenated and species-tree approaches for an ancient, rapid radiation.

TL;DR: The phylogenetic results suggest a non-traditional biogeographic scenario in which pleurodonts originated in the Northern Hemisphere and subsequently spread southward into South America.
