Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

Species' phenotypic characteristics often remain unchanged over long stretches of
geological time. Stabilizing selection—in which fitness is highest for intermediate …

Deep-sea lineages are generally thought to arise from shallow-water ancestors, but this
hypothesis is based on a relatively small number of taxonomic groups. Anthozoans, which …

Target capture has emerged as an important tool for phylogenetics and population genetics
in nonmodel taxa. Whereas developing taxon‐specific capture probes requires sustained …

The evolution of key innovations—unique features that enable a lineage to interact with the
environment in a novel way—may drive broad patterns of adaptive diversity. However …

Understanding how the early stages of sexual signal diversification proceed is critically
important because these microevolutionary dynamics directly shape species trajectories and …

Abstract Background Lake Tanganyika belongs to the East African Great Lakes and is well
known for harbouring a high proportion of endemic and morphologically distinct genera, in …

Gene flow and reticulation are increasingly recognized as important processes in the
diversification of many taxonomic groups. With the increasing ease of collecting genomic …

Positive allometry of signalling traits has often been taken as evidence for sexual selection.
However, few studies have explored interspecific differences in allometric scaling …

Speciation is facilitated when traits under divergent selection also act as mating cues.
Fluctuations in sensory conditions can alter signal perception independently of adaptation to …
