Circadian plasticity evolves through regulatory changes in a neuropeptide gene

Nature, Published online: 16 October 2024; doi:10.1038/s41586-024-08056-x

We provide evidence that circadian plasticity has diverged through evolution of the neuropeptide gene Pdf, conferring a selective advantage for Drosophila melanogaster at elevated latitude, whereas Drosophila sechellia probably suffers fitness costs outside its range.
