Researchers from the University of Illinois at Urbana-Champaign have found remarkable stability in a hybrid zone between two species of manakins in Panama over the past 30 years. Published in Evolution, the study led by Kira Long reveals that the genomic center and phenotypic transition zone have remained relatively unchanged, with less than 3% of genomic markers showing variation. While the hybrids, genetically mixed between golden-collared and white-collared manakins, visually resemble golden-collared manakins, only one phenotypic trait—belly color—has shifted over time. This stability suggests the hybrids are successfully adapting to their environment, with further research needed to understand the role of female choice in this dynamic.
