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 …

Almost nothing is known about the diets of bathypelagic fishes, but functional morphology
can provide useful tools to infer ecology. Here we quantify variation in jaw and tooth …

Oceans are home to much of the world's biodiversity, but we know little about the processes
driving speciation in marine ecosystems with few geographical barriers to gene flow …

Anglerfish are creatures of the deep ocean, featuring glowing lures, huge, toothy mouths
and parasitic males physically attached to females. A new study finds that genomic …

Intraspecific diversity promotes evolutionary change, and when partitioned among
geographic regions or habitats can form the basis for speciation. Marine species live in an …

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 …

Natural selection is often assumed to drive parallel functional diversification of the sexes. But
males and females exhibit fundamental differences in their biology, and it remains largely …

The fossil record of marine animals suggests that diversity-dependent processes exerted
strong control on biodiversification: after the Ordovician Radiation, genus richness did not …

To investigate the origins and stages of vertebrate adaptive radiation, we reconstructed the
spatial and temporal histories of genetic variants underlying major phenotypic axes of …

Background Adaptive radiation is the process by which a single ancestral species diversifies
into many descendants adapted to exploit a wide range of habitats. The appearance of …
