Genetic variation, which is generated by mutation, recombination and gene flow, can reduce
the mean fitness of a population, both now and in the future. This 'genetic load'has been …

New finds in the palaeoanthropological and genomic records have changed our view of the
origins of modern human ancestry. Here we review our current understanding of how the …

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 …

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 …

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 …

INTRODUCTION Coral reefs worldwide are suffering losses at an alarming rate as a result of
anthropogenic climate change. Increased seawater temperatures, even only slightly above …

Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

Domesticated grapevines spread to Europe around 3,000 years ago. Previous studies have
revealed genomic signals of introgression from wild to cultivated grapes in Europe, but the …
