Understanding how diversity evolves and is maintained is critical to predicting the future
trajectories of ecosystems under climate change; however, our understanding of these …

Rapid adaptive radiation poses two distinct questions apart from speciation and adaptation:
What happens after one speciation event and how do some lineages continue speciating …

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

The transition from 'well-marked varieties' of a single species into 'well-defined species'—
especially in the absence of geographic barriers to gene flow (sympatric speciation)—has …

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

Speciation is frequently initiated but rarely completed, a phenomenon hypothesized to arise
due to the failure of nascent lineages to persist. Although a failure to persist often has …

Some of the most spectacular adaptive radiations begin with founder populations on remote
islands. How genetically limited founder populations give rise to the striking phenotypic and …

Adaptive divergence is widely accepted as a contributor to speciation and the maintenance
of species integrity. However, the mechanisms leading to reproductive isolation, the genes …

Ecological divergence without geographic isolation, as an early speciation process that may
lead finally to reproductive isolation through natural selection, remains a captivating topic in …

Speciation is the result of evolutionary processes that generate barriers to gene flow
between populations, facilitating reproductive isolation. Speciation is typically studied via …
