Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

Hybridization is an evolutionary phenomenon that has fascinated biologists for centuries.
Prior to the advent of whole-genome sequencing, it was clear that hybridization had played …

Adaptive radiation is the likely source of much of the ecological and morphological diversity
of life,,–. How adaptive radiations proceed and what determines their extent remains unclear …

Genome-scale sequence data have invigorated the study of hybridization and introgression,
particularly in animals. However, outside of a few notable cases, we lack systematic tests for …

Speciation rates vary considerably among lineages, and our understanding of what drives
the rapid succession of speciation events within young adaptive radiations remains …

In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

We used 20 de novo genome assemblies to probe the speciation history and architecture of
gene flow in rapidly radiating Heliconius butterflies. Our tests to distinguish incomplete …

The hundreds of cichlid fish species in Lake Malawi constitute the most extensive recent
vertebrate adaptive radiation. Here we characterize its genomic diversity by sequencing 134 …

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

Speciation is the process by which barriers to gene flow evolve between populations.
Although we now know that speciation is largely driven by natural selection, knowledge of …
