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 …

Although some lineages of animals and plants have made impressive adaptive radiations
when provided with ecological opportunity, the propensities to radiate vary profoundly …

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 …

Hybridization, or interbreeding between different taxa, was traditionally considered to be
rare and to have a largely detrimental impact on biodiversity, sometimes leading to the …

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 …

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 …

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 …

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 …

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