Genome-wide evidence for speciation with gene flow in Heliconius butterflies.
Most speciation events probably occur gradually, without complete and immediate reproductive isolation, but the full extent of gene flow between diverging species has rarely been characterized on aExpand

Chromosomal rearrangements maintain a polymorphic supergene controlling butterfly mimicry
Supergenes are tight clusters of loci that facilitate the co-segregation of adaptive variation, providing integrated control of complex adaptive phenotypes. Polymorphic supergenes, in which specificExpand

Genome‐wide patterns of divergence and gene flow across a butterfly radiation
The Heliconius butterflies are a diverse recent radiation comprising multiple levels of divergence with ongoing gene flow between species. The recently sequenced genome of Heliconius melpomeneExpand

Complex modular architecture around a simple toolkit of wing pattern genes
Identifying the genomic changes that control morphological variation and understanding how they generate diversity is a major goal of evolutionary biology. In Heliconius butterflies, a small numberExpand

Hybrid trait speciation and Heliconius butterflies
Homoploid hybrid speciation (HHS) is the establishment of a novel species through introgressive hybridization without a change in chromosome number. We discuss different routes by which this mightExpand

Two sisters in the same dress: Heliconius cryptic species
BackgroundSister species divergence and reproductive isolation commonly results from ecological adaptation. In mimetic Heliconius butterflies, shifts in colour pattern contribute to pre- andExpand

Hybrid sterility, Haldane's rule and speciation in Heliconius cydno and H. melpomene.
Most genetic studies of Haldane's rule, in which hybrid sterility or inviability affects the heterogametic sex preferentially, have focused on Drosophila. It therefore remains unclear to what extentExpand

Natural Selection and Genetic Diversity in the Butterfly Heliconius melpomene
A combination of selective and neutral evolutionary forces shape patterns of genetic diversity in nature. Among the insects, most previous analyses of the roles of drift and selection in shapingExpand

Evolutionary Novelty in a Butterfly Wing Pattern through Enhancer Shuffling
An important goal in evolutionary biology is to understand the genetic changes underlying novel morphological structures. We investigated the origins of a complex wing pattern found among AmazonianExpand

Assortative Mating Preferences Among Hybrids Offers a Route to Hybrid Speciation
Homoploid speciation generates species without a change in chromosome number via introgressive hybridization and has been considered rare in animals. Heliconius butterflies exhibit bright aposematicExpand
