Species-specific description: Campagna et al. (2022): "Chestnut-bellied Monarchs (Monarcha castaneiventris ugiensis) from two archipelagos in the Solomon Islands have evolved entirely black plumage from a chestnut ancestor (Monarcha castaneiventris megarhynchus), a phenomenon known as island melanism. We obtain and analyze whole genome sequences using traditional summary statistics and new methods that combine inference of the ancestral recombination graph with machine learning. We find multiple lines of evidence for independent selective sweeps on the MC1R and ASIP genes, a receptor/ligand pair which regulates the production of melanin. Melanism on each archipelago is mediated by mutations in one of these two genes."

Molecular basis: Campagna et al. (2022) confirm findings from their earlier studies, suggesting that a non-synonymous Ile55Thr substitution in the ASIP gene is the likely causal variant for entirely black plumage in birds from the Ugi island.
