Bony fishes are the principal group of backboned animals in contemporary aquatic settings.
Extant species are the focus of a vigorous program of macroevolutionary research, but …

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 …

The deep sea contains a surprising diversity of life, including iconic fish groups such as
anglerfishes and lanternfishes. Still,> 65% of marine teleost fish species are restricted to the …

Major ecological transitions are thought to fuel diversification, but whether they are
contingent on the evolution of certain traits called key innovations 1 is unclear. Key …

Phylogenomic analysis of large genome-wide sequence data sets can resolve phylogenetic
tree topologies for large species groups, help test the accuracy of and improve resolution for …

Many of the most dramatic patterns in biological diversity are created by “Perfect Storms”—
rare combinations of mutually reinforcing factors that push origination, extinction, or diversity …

Key innovations, traits that provide species access to novel niches, are thought to be a major
generator of biodiversity. One commonly cited example of key innovation is pharyngognathy …

Colonization of a novel habitat is often followed by phenotypic diversification in the wake of
ecological opportunity. However, some habitats should be inherently more constraining than …

The development of a movable jaw is one of the most important transitions in the
evolutionary history of animals. 1 Jawed vertebrates rapidly diversified after appearing …

The colonization of a novel geographic area is a classic source of ecological opportunity.
