Aposematic theory has historically predicted that predators should select for warning signals
to converge on a single form, as a result of frequency‐dependent learning. However …

Interspecific hybridization is the process where closely related species mate and produce
offspring with admixed genomes. The genomic revolution has shown that hybridization is …

Identifying the genomic changes that control morphological variation and understanding
how they generate diversity is a major goal of evolutionary biology. In Heliconius butterflies …

The optix gene has been implicated in butterfly wing pattern adaptation by genetic
association, mapping, and expression studies. The actual developmental function of this …

Population Genetics and Microevolutionary Theory Explore the fundamentals of the
biological implications of population genetic theory In the newly revised Second Edition of …

Mimicry is a classic example of adaptation through natural selection. The traditional focus of
mimicry research has been on defence in animals, but there is now also a highly-developed …

Batesian mimicry, in which harmless species (mimics) deter predators by deceitfully imitating
the warning signals of noxious species (models), generates striking cases of phenotypic …

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 …

Background Although hybridization is thought to be relatively rare in animals, the raw
genetic material introduced via introgression may play an important role in fueling …

Butterfly wing patterns are a model system for studying the evolution and development of
adaptive traits. Zhang et al. combine RNA-seq and CRISPR/Cas9... Despite the variety …
