Abstract excerpt
Divergent selection across species ranges does not always translate into observable morphological divergence. Genomic approaches agnostic to traits or groups of populations under selection can reveal cryptic genetic diversity and provide insights into the nature of local adaptation. Here, we use such an approach to investigate local adaptation in the zebra butterfly, Heliconius charithonia. This species is widely...
