Abstract The phylogeny of living and fossil snakes is assessed using likelihood and parsimony approaches and a dataset combining 263 morphological characters with mitochondrial (2693 bp) and nuclear (1092 bp) gene sequences. The ‘no common mechanism’ (NCMr) and ‘Markovian’ (Mkv) models were employed for the morphological partition in likelihood analyses; likelihood scores in the NCMr model were more closely correlated with parsimony tree lengths. Both models accorded relatively less weight to… 
Phylogeny and divergence times of filesnakes (Acrochordus): inferences from morphology, fossils and three molecular loci.
Squamate Phylogenetics, Molecular Branch Lengths, and Molecular Apomorphies: A Response to McMahan et al.
It is demonstrated that counting the molecular apomorphies along a given branch is a poor measure of support for a clade and that the molecular data do not provide support for the morphology-based squamate phylogeny as the optimal topology.
Combining morphological and molecular data resolves the phylogeny of Squilloidea (Crustacea : Malacostraca)
The phylogeny of Squilloidea is inferred using a combined dataset comprising 75 somatic morphological characters and four molecular markers to obtain a well resolved and strongly supported phylogeny that is largely congruent with previous estimates.
Phylogeny, biogeography and classification of the snake superfamily Elapoidea: a rapid radiation in the late Eocene
The major elapoid and elapid lineages are identified, a phylogenetic classification system for the superfamily is presented, and results imply rapid basal diversification in both clades in the late Eocene of Africa and the mid‐Oligocene of the Oriental region.
Cytogenetics and Molecular Data in Snakes: A Phylogenetic Approach
It is found that cytogenetic comparisons could provide a useful tool to investigate intergeneric and tribal relationships within the extremely diverse neotropical xenodontine snakes and snake phylogeny based on mitochondrial genome sequences is largely consistent with the relationship obtained using nuclear genes.
The problems of molecular phylogenetics with the example of squamate reptiles: Mitochondrial DNA markers
The review supports the viewpoint that mitochondrial genes and their fragments fail to provide reliable evolutionary markers when considered without a thorough study of the environmental conditions and life of the taxa.
Branch lengths, support, and congruence: testing the phylogenomic approach with 20 nuclear loci in snakes.
This study examines the relationships between branch lengths, branch support, and congruence among genes using a data set of 20 nuclear loci for 50 species of snakes to support the hypothesis that short branches may be very difficult to confidently resolve, even with large, multilocus data sets.
Palaeoecological inferences for the fossil Australian snakes Yurlunggur and Wonambi (Serpentes, Madtsoiidae)
The inner ear of Yurlunggur most closely resembles both that of certain semiaquatic snakes and that of some semifossorial snakes, and osteology, palaeoclimatic data and the palaeobiogeographic distribution of these two snakes are consistent with these inferred ecological differences.
Evolution of sex chromosomes in Sauropsida.
This work finds support for the common ancestor of amphisbaenians and whiptail lizards possessing the XY GSD mechanism, while the ancestors of Testudines and Crocodylia, as well as the larger group Archosauromorpha are inferred to have exhibited TSD.
Comparative Skull Morphology of Uropeltid Snakes (Alethinophidia: Uropeltidae) with Special Reference to Disarticulated Elements and Variation
Trends in the relative enlargement of the sensory capsules, reduction in cranial ossification and dentition, fusion of elements, and the appearance of novel morphological conditions, may be related to fossoriality and miniaturization in some uropeltid taxa and may complicate analysis of relationships within Uropeltidae and among alethinophidian snakes.


Phylogenetics of advanced snakes (Caenophidia) based on four mitochondrial genes.
Phylogenetic relationships among advanced snakes and the position of the genus Acrochordus relative to colubroid taxa are investigated by phylogenetic analysis of fragments from four mitochondrial genes representing 62 caenophidian genera and 5 noncaenophidians, and Xenoderminae appears to be the sister group to the Colubroidea.
A molecular approach to discerning the phylogenetic placement of the enigmatic snake Xenophidion schaeferi among the Alethinophidia
Results from ML and BI analyses suggest a possible sister taxon relationship between Xenophidion schaeferi and the Bolyeridae and strong statistical support indicates that Xenophiidae is a member of a clade that contains Pythonidae, Loxocemidae, Uropeltidae, Xenopeltidae and Bolyeriidae.
Snake phylogeny based on osteology, soft anatomy and ecology
Relationships between the major lineages of snakes are assessed based on a phylogenetic analysis of the most extensive phenotypic data set to date (212 osteological, 48 soft anatomical, and three
Synergistic effects of combining morphological and molecular data in resolving the phylogeny of butterflies and skippers
This work presents the first well supported phylogenetic hypothesis for the butterflies and skippers based on a total-evidence analysis of both traditional morphological characters and new molecular characters from three gene regions (COI, EF-1α and wingless).
Phylogenetic relationships of colubroid snakes based on mitochondrial DNA sequences
The tree resulting from transversion parsimony analysis rooted with Acrochordus is regarded as the best current estimate of colubroid phylogenetic relationships, suggesting that long-branch problems can severely compromise elucidation of Colubroid relationships if limited taxonomic sampling strategies are followed.
Higher-level snake phylogeny inferred from mitochondrial DNA sequences of 12S rRNA and 16S rRNA genes.
Snakes were found to constitute a monophyletic group, with the scolecophidians (blind snakes) as the most basal lineages (CP = 99%), and this finding supports the hypothesis that snakes underwent a subterranean period early in their evolution.
Molecular phylogenetics of squamata: the position of snakes, amphisbaenians, and dibamids, and the root of the squamate tree.
A molecular phylogenetic study of 69 squamate species suggests that similar states in Sphenodon and Iguania result from homoplasy, and species previously placed in Scleroglossa, Varanoidea, and several other higher taxa do not form monophyletic groups.
