Phylogenomics has revealed the remarkable frequency with which introgression occurs
across the tree of life. These discoveries have been enabled by the rapid growth of methods …

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 …

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 …

Intrinsic postzygotic isolation typically appears as reduced viability or fertility of interspecific
hybrids caused by genetic incompatibilities between diverged parental genomes …

Research on the genomic architecture of speciation has increasingly revealed the
importance of structural variants (SVs) that affect the presence, abundance, position, and/or …

Pan-genomic studies aim at representing the entire sequence diversity within a species to
provide useful resources for evolutionary studies, functional genomics and breeding of …

Inversions are structural mutations that reverse the sequence of a chromosome segment
and reduce the effective rate of recombination in the heterozygous state. They play a major …

Inversions are thought to play a key role in adaptation and speciation, suppressing
recombination between diverging populations. Genes influencing adaptive traits cluster in …

Across hybrid zones, the sex chromosomes are often more strongly differentiated than the
autosomes. This is regularly attributed to the greater frequency of reproductive …

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