Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the
designation of taxonomic groups on the basis of morphological similarity. Starting in the late …

Evolutionary stasis characterizes lineages that seldom speciate and show little phenotypic
change over long stretches of geological time. Although lineages that appear to exhibit …

The separation of closely related terrestrial or freshwater species by vast marine barriers
represents a biogeographical riddle. Such cases can provide evidence for vicariance, a …

Aim Lungfishes are one of the two surviving clades from the once diverse grade of lobe‐

Abstract Background The deep (> 200 m) ocean floor is often considered to be a refugium of
biodiversity; many benthic marine animals appear to share ancient common ancestry with …
