A phylogeny of tetrapods is inferred from nearly complete sequences of the nuclear RAG-1 gene sampled across 88 taxa encompassing all major clades, analyzed via parsimony and Bayesian methods, which systematically underestimates divergence dates within archosaurs.

An alternative approach in which spatial models of predicted species distributions under serial paleoclimates are compared with a molecular phylogeography, in this case for a snail endemic to the rainforests of North Queensland, Australia, is developed.
Sequence evolution and phylogenetic signal in control-region and cytochrome b sequences of rainbow fishes (Melanotaeniidae).
It is deduced that both the control region and cytochrome b are appropriate for population genetic studies but that the control area is less effective than cy tochrome b for resolving relationships among divergent lineages of rainbow fishes.
Phylogeny of Australasian agamid lizards based on nuclear and mitochondrial genes: implications for morphological evolution and biogeography
Tree topology, inferred divergence dates, palaeogeographical and palaeoclimatic data are all consistent with Miocene immigration into Australia from the north by mesic forest ecomorphs, followed by initial diversification in mesic habitats before radiation into xeric habitats facilitated by increasing aridity.
Reticulate evolution and the origins of ribosomal internal transcribed spacer diversity in apomictic Meloidogyne.
The diversity of ITSs in M. arenaria, M. javanica, and M. incognita is suggested to be due to hybrid origins from closely related females (as inferred from mtDNA) and combinations of more diverse paternal lineages.
Accelerated speciation in colour-polymorphic birds
The results provide empirical support for the general proposition, dating from classical evolutionary theory, that colour polymorphism can increase speciation rates and are corroborated by evidence from a species-level molecular phylogeny of passerines that polymorphic species tend to be younger than monomorphic species.
Nucleotide polymorphisms and an improved PCR-based mtDNA diagnostic for parthenogenetic root-knot nematodes (Meloidogyne spp.)
Ce nouveau test represente une amelioration par rapport aux tests PCR sur DNA mitochondrial appliques aux Meloidogyne en ce sens qu'il permet la discrimination entre un plus grand nombre d'especes et de races.
Lygosomine phylogeny and the origins of Australian scincid lizards
A time‐calibrated phylogeny for Lygosominae is presented that provides the necessary temporal framework for assessing the contributions of immigration from Asia and of Gondwanan inheritance in the derivation of the Australian scincid fauna.
Beyond the prolegomenon: a molecular phylogeny of the Australian camaenid land snail radiation
A phylogenetic and biogeographically condign arrangement of camaenid land snails is provided as the basis for future elaborations, highlighting (1) the repeated radiation of shell forms, and (2) that the current higher taxonomy is unacceptable.
Phylogeny of snakes (Serpentes): Combining morphological and molecular data in likelihood, Bayesian and parsimony analyses
The combined analyses resulted in a novel and stable position of uropeltines and cylindrophiines as the second‐most basal clade of alethinophidians; the limbed marine pachyophiids, along with Dinilysia and Wonambi, were always basal to all living snakes.
