In the wake of constant improvements in sequencing technologies, numerous insect
genomes have been sequenced. Currently, 1219 insect genome‐sequencing projects have …

Highlights•The genomic landscape of introgression carries information about the fitness
consequences of hybridisation.•Studies are moving from documenting single examples to …

Chromosomes are a central unit of genome organization. One-tenth of all described species
on Earth are butterflies and moths, the Lepidoptera, which generally possess 31 …

Hybridization allows adaptations to be shared among lineages and may trigger the evolution
of new species,. However, convincing examples of homoploid hybrid speciation remain rare …

A primary roadblock to our understanding of speciation is that it usually occurs over a
timeframe that is too long to study from start to finish. The idea of a speciation continuum …

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 …

Hybridisation and introgression can dramatically alter the relationships among groups of
species, leading to phylogenetic discordance across the genome and between populations …

Chromosome rearrangements are thought to promote reproductive isolation between
incipient species. However, it is unclear how often, and under what conditions, fission and …

Understanding the genetic basis of reproductive isolation is a central issue in the study of
speciation. Structural variants (SVs); that is, structural changes in DNA, including inversions …

Under the neutral theory, genetic diversity is expected to increase with population size.
While comparative analyses have consistently failed to find strong relationships between …
