A pangenomic approach reveals the sources of genetic variation fueling the rapid radiation of Capuchino Seedeaters

María Recuerda, Simón Kraemer, Jonas Rafael Rodrigues Rosoni…·Leonardo Campagna

The paper uses a pangenome of Capuchino Seedeaters to show that small SNPs and indels, not large structural variants, drive species divergence and plumage diversity.
