In recent articles published in Molecular Phylogenetics and Evolution, Mark Springer and
John Gatesy (S&G) present numerous criticisms of recent implementations and testing of the …

Adaptive radiation is a response to natural selection and ecological opportunity involving
diversification of species and associated adaptations. Although evolutionary biologists have …

Living turtles are characterized by extraordinarily low species diversity given their age. The
clade's extensive fossil record indicates that climate and biogeography may have played …

The advent and maturation of algorithms for estimating species trees—phylogenetic trees
that allow gene tree heterogeneity and whose tips represent lineages, populations and …

The species representation of public databases is growing rapidly and permits increasingly
detailed phylogenetic inferences. We present a supermatrix based on all gene sequences of …

Phylogeneticists are increasingly assembling genome-scale data sets that include hundreds
of genes to resolve their focal clades. Although these data sets commonly include a …

Snakes in the families Boidae and Pythonidae constitute some of the most spectacular
reptiles and comprise an enormous diversity of morphology, behavior, and ecology. While …

Iguanian lizards form a diverse clade whose members have been the focus of many
comparative studies of ecology, behavior, and evolution. Despite the importance of …

The heterogeneity of signals in the genomes of diverse organisms poses challenges for
traditional phylogenetic analysis. Phylogenetic methods known as “species tree” methods …

An accurate understanding of species diversity is essential to studies across a wide range of
biological subdisciplines. However, delimiting species remains challenging in evolutionary …
