1976. Sukhanov, S. B. Our analyses show that weakly supported clades are associated with relatively short branches for which individual genes often show conflicting relationships. This template contains a phylogeny for squamate reptiles (lizards and snakes) based on 52 genes and 4162 species in the combined phylogenomic and supermatrix analysis by Zheng & Wiens (2016)) [1] . Together they form a unique fingerprint.

Remarkably, we find that the distinctive scolecophidians (blind snakes) are paraphyletic with respect to other snakes, suggesting that snakes were primitively burrowers and subsequently re-invaded surface habitats. AB - Squamate reptiles (lizards and snakes) are one of the most diverse groups of terrestrial vertebrates. Omitting |wrap= allows a custom cladogram to be build around the selection from the template.

Our results strongly resolve most squamate relationships and reveal some surprising results. Our analyses show that weakly supported clades are associated with relatively short branches for which individual genes often show conflicting relationships. Squamate reptiles (lizards and snakes) are one of the most diverse groups of terrestrial vertebrates. Essays commemorating Charles L. Camp.

In contrast to most other recent studies, we find that dibamids and gekkotans are together the sister group to all other squamates. The template optionally uses {{clade transclude}} as a wrapper that allows partial transclusion of parts of the phylogenetic tree selected by |label= or |subtree=. Squamate reptiles (lizards and snakes) are one of the most diverse groups of terrestrial vertebrates.

Recent molecular analyses have suggested a very different squamate phylogeny relative to morphological hypotheses, but many aspects remain uncertain from molecular data. Remarkably, we find that the distinctive scolecophidians (blind snakes) are paraphyletic with respect to other snakes, suggesting that snakes were primitively burrowers and subsequently re-invaded surface habitats.

This is a documentation subpage for Template:Phylogeny/Squamata.

This template contains a phylogeny for squamate reptiles (lizards and snakes) based on 52 genes and 4162 species in the combined phylogenomic and supermatrix analysis by Zheng & Wiens (2016))[1]. Early estimates of squamate phylogeny [21] and recent studies based on morphological data [13-15,22] consistently supported a basal division between Iguania (including

Molecular phylogenetics of squamata: the position of snakes, amphisbaenians, and dibamids, and the root of the squamate tree. title = "Resolving the phylogeny of lizards and snakes (Squamata) with extensive sampling of genes and species". Abstract Squamata (amphisbaenians, “lizards”, mosasaurs, and snakes) is an extremely diverse clade with a rich fossil record. There is little consensus about the interrelationships of the major squamate clades (i.e., Iguania, Gekkota, Scincomorpha, Anguimorpha, Amphisbaenia, and Serpentes), or even the membership of some of these clades. Comparative morphology of the lepidosaur tongue and its relevance to squamate phylogeny. Remarkably, we find that the distinctive scolecophidians (blind snakes) are paraphyletic with respect to other snakes, suggesting that snakes were primitively burrowers and subsequently re-invaded surface habitats.

Our results strongly resolve most squamate relationships and reveal some surprising results. In contrast to most other recent studies, we find that dibamids and gekkotans are together the sister group to all other squamates. John J. Wiens, Carl R. Hutter, Daniel G. Mulcahy, Brice P.

In contrast to most other recent studies, we find that dibamids and gekkotans are together the sister group to all other squamates.

Dive into the research topics of 'Resolving the phylogeny of lizards and snakes (Squamata) with extensive sampling of genes and species'. Morphology-based cladistic analyses typically agree only that the major dichotomy in extant squamates is between Iguania and all other taxa. / Wiens, John J.; Hutter, Carl R.; Mulcahy, Daniel G.; Noonan, Brice P.; Townsend, Ted M.; Sites, Jack W.; Reeder, Tod W.

These latter results have important implications for all studies that attempt to resolve phylogenies with large-scale phylogenomic datasets. In contrast to most other recent studies, we find that dibamids and gekkotans are together the sister group to all other squamates.
