The idea that South America was an island continent over most of the Cenozoic, during
which its unusual mammalian faunas evolved in isolation, is outstandingly influential in …

Improved understanding of tick phylogeny has allowed testing of some biogeographical
patterns. On the basis of both literature data and a meta-analysis of available sequence …

A phylogenetic analysis of sequences from 503 species of hylid frogs and four outgroup taxa
resulted in 16,128 aligned sites of 19 genes. The molecular data were subjected to a …

The fossil record suggests a rapid radiation of placental mammals following the Cretaceous–
Paleogene (K–Pg) mass extinction 65 million years ago (Ma); nevertheless, molecular time …

Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are
fundamental to nearly every evolutionary model and process. Rates need dates. There is …

The estimation of phylogenetic divergence times from sequence data is an important
component of many molecular evolutionary studies. There is now a general appreciation …

Taxonomy of Australian Mammals utilises the latest morphometric and genetic research to
develop the most up to date and comprehensive revision of the taxonomy of Australian …

The current literature on marsupial phylogenetics includes numerous studies based on
analyses of morphological data with limited sampling of Recent and fossil taxa, and many …

Background Variation is a naturally occurring phenomenon that is observable at all levels of
morphology, from anatomical variations of DNA molecules to gross variations between …

There are few putative macroevolutionary trends or rules that withstand scrutiny. Here, we
test and verify the purported tendency for animal clades to reach their maximum …
