Estimating Divergence Times from Molecular Data on Phylogenetic and Population Genetic Timescales
TLDR
A review of recent advances in estimating divergence times from molecular data, emphasizing the continuum between processes at the phylogenetic and population genetic scales, and the importance of model testing during the process of divergence time estimation.
Phylogeny of the Colubroidea (Serpentes): new evidence from mitochondrial and nuclear genes.
TLDR
This work inferred the phylogeny of colubroids with special reference to the largest family, the Colubridae, and proposed an updated classification based on the reallocation of species as indicated by the inferred phylogeny.
MITOCHONDRIAL DNA PHYLOGEOGRAPHY OF THE POLYTYPIC NORTH AMERICAN RAT SNAKE (ELAPHE OBSOLETA): A CRITIQUE OF THE SUBSPECIES CONCEPT
TLDR
Mitochondrial DNA analysis of the polytypic snake, Elaphe obsoleta, yields well-supported clades that do not conform to any of the currently accepted subspecies, and underscores the potential problems of recognizing subspecies based on one or a few characters.
Testing Whether Certain Traits have Caused Amplified Diversification: An Improved Method Based on a Model of Random Speciation and Extinction
One of the more striking patterns of organismal diversity isthe repeated occurrence of taxonomic groups that are conspicuously large as compared to related groups. Well-known examples include
MITOCHONDRIAL DNA PHYLOGEOGRAPHY OF THE POLYTYPIC NORTH AMERICAN RAT SNAKE (ELAPHE OBSOLETA): A CRITIQUE OF THE SUBSPECIES CONCEPT
Subspecies have been considered artificial subdivisions of species, pattern classes, or incipient species. However, with more data and modern phylogenetic techniques, some subspecies may be found to
Inferring species trees from gene trees: a phylogenetic analysis of the Elapidae (Serpentes) based on the amino acid sequences of venom proteins.
TLDR
The results support a division of the elapids examined into sister groups of the Australian and marine (laticaudines and hydrophiines) species, and the African and Asian species.
Phylogenetic relationships of elapid snakes based on cytochrome b mtDNA sequences.
TLDR
To resolve the relationships of the African, American, and Asian species to each other and to the marine/Australo-Melanesian clade, the entire cytochrome b gene for 28 elapids was sequenced.

TLDR
Molecular systematic studies suggest that diversification rates were lower in the Pleistocene than for the preceding period, although from molecular evidence the authors cannot discern whether speciation rates decreased or extinction rates increased.
Pleistocene Speciation and the Mitochondrial DNA Clock
TLDR
It is concluded that sequence divergence values and corresponding estimates of times of evolutionary divergence between presumptive sister pairs of North American songbirds were sufficiently large to reject a Late Pleistocene Origins model (LPO model, 2) for most species.
A molecular approach to discerning the phylogenetic placement of the enigmatic snake Xenophidion schaeferi among the Alethinophidia
TLDR
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.
