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. Stanford University Press, Stanford, California. Resolving the phylogeny of lizards and snakes (Squamata) with extensive sampling of genes and species.
Our analyses show that weakly supported clades are associated with relatively short branches for which individual genes often show conflicting relationships. Comparative morphology of the lepidosaur tongue and its relevance to squamate phylogeny. keywords = "Phylogenomics, Phylogeny, Reptiles". Our analyses show that weakly supported clades are associated with relatively short branches for which individual genes often show conflicting relationships. The phylogeny of squamate reptiles (lizards, snakes, and amphisbaenians) inferred from nine nuclear protein-coding genes Nicolas Vidala,b,∗, S. Blair Hedgesa a Department of Biology and Astrobiology Research Center, 208 Mueller Lab., Pennsylvania State University, University Park, PA 16802-5301, USA Squamate phylogenetics has changed radically in the last 10 years, revealing major conflicts between the re-sults of morphological and molecular analyses [12]. We assembled a dataset of 192 carefully selected species—51 extinct and 141 extant—and 976 apomorphies distributed among 610 phenotypic characters to investigate the phylogeny of Squamata (“lizards,” including snakes and amphisbaenians). In contrast to most other recent studies, we find that dibamids and gekkotans are together the sister group to all other squamates. 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. Recent molecular analyses have suggested a very different squamate phylogeny relative to morphological hypotheses, but many aspects remain uncertain from molecular data. Recent molecular analyses have suggested a very different squamate phylogeny relative to morphological hypotheses, but many aspects remain uncertain from molecular data. Squamate reptiles (lizards and snakes) are one of the most diverse groups of terrestrial vertebrates. Our results strongly resolve most squamate relationships and reveal some surprising results.
Resolving the phylogeny of lizards and snakes (Squamata) with extensive sampling of genes and species, Agricultural and Biological Sciences (miscellaneous), Agricultural and Biological Sciences(all). Here, we analyse higher-level squamate phylogeny 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. It contains usage information, categories and other content that is not part of the original template page.
Together they form a unique fingerprint. Squamate reptiles (lizards and snakes) are one of the most diverse groups of terrestrial vertebrates. However, studies of squamate biology are presently hampered by uncertainty over their 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. / Wiens, John J.; Hutter, Carl R.; Mulcahy, Daniel G.; Noonan, Brice P.; Townsend, Ted M.; Sites, Jack W.; Reeder, Tod W. T1 - Resolving the phylogeny of lizards and snakes (Squamata) with extensive sampling of genes and species. These latter results have important implications for all studies that attempt to resolve phylogenies with large-scale phylogenomic datasets. The template optionally uses {{clade transclude}} as a wrapper that allows partial transclusion of parts of the phylogenetic tree selected by |label= or |subtree=. Finally, we find that some clades remain poorly supported, despite our extensive data.
Pages 569-598 in R. Estes and G. Pregill, eds., Phylogenetic relationships of the lizard families. Our analyses show that weakly supported clades are associated with relatively short branches for which individual genes often show conflicting relationships. . Higher-level squamate phylogeny is currently considered unresolved because of strong conflicts between hypotheses based on separate analyses of morphological and molecular datasets [8, …
Our results strongly resolve most squamate relationships and reveal some surprising results.
N2 - Squamate reptiles (lizards and snakes) are one of the most diverse groups of terrestrial vertebrates. By continuing you agree to the use of cookies. 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]. Our results strongly resolve most squamate relationships and reveal some surprising results. Abstract Squamata (amphisbaenians, “lizards”, mosasaurs, and snakes) is an extremely diverse clade with a rich fossil record. Morphology-based cladistic analyses typically agree only that the major dichotomy in extant squamates is between Iguania and all other taxa. Here, we analyse higher-level squamate phylogeny 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.
