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 …

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 …
