A great tradition in macroevolution and systematics has been the ritual squabbling between
palaeontologists and molecular biologists. But, because both sides were talking past each …

This article reviews the most common methods used today for estimating divergence times
and rates of molecular evolution. The methods are grouped into three main classes:(1) …

We present a comprehensive revision and synthesis of the higher-level classification of the
barnacles (Crustacea: Thecostraca) to the genus level and including both extant and fossils …

Several models have been proposed to relax the molecular clock in order to estimate
divergence times. However, it is unclear which model has the best fit to real data and should …

• Premise of the study: Land plants play an essential role in the evolution of terrestrial life.
Their time of origin and diversification is fundamental to understanding the evolution of life …

An ambitious, yet fundamental goal for comparative biology is to understand the
evolutionary relationships for all of life. However, many important taxonomic groups have …

Since the first discovery of deep-sea hydrothermal vents along the Galápagos Rift in 1977,
numerous vent sites and endemic faunal assemblages have been found along mid-ocean …

Phylogenetic relationships among all of the major decapod infraorders have never been
estimated using molecular data, while morphological studies produce conflicting results. In …

Abstract Background Melon, Cucumis melo, and cucumber, C. sativus, are among the most
widely cultivated crops worldwide. Cucumis, as traditionally conceived, is geographically …

Lobsters are a ubiquitous and economically important group of decapod crustaceans that
include the infraorders Polychelida, Glypheidea, Astacidea and Achelata. They include …
