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 …

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 …

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 …

The establishment of reproductive barriers between populations can fuel the evolution of
new species. A genetic framework for this process posits that “incompatible” interactions …

Genomic data has opened new possibilities to understand how organisms change over
time, and could enable the discovery of previously undescribed species. Although taxonomy …

Global environmental changes strongly impact wild and domesticated species biology and
their associated ecosystem services. For crops, global warming has led to significant …

Hybridization and gene flow between species appears to be common. Even though it is
clear that hybridization is widespread across all surveyed taxonomic groups, the magnitude …

Sympatric speciation illustrates how natural and sexual selection may create new species in
isolation without geographic barriers. However, recent genomic reanalyses of classic …

Maternally transmitted Wolbachia infect about half of insect species, yet the predominant
mode (s) of Wolbachia acquisition remains uncertain. Species-specific associations could …

An increasing number of phylogenomic studies have documented a clear “footprint” of
postspeciation introgression among closely related species. Nonetheless, systematic …
