Digest: Sexual dimorphism and signs of selection in the dewlaps of female <i>Anolis</i> lizards

Although Anolis lizards have been well studied and are known to frequently exhibit sexual dimorphism, little is still known about the ecology and evolution of females as opposed to males. Westeen et al. (2025) find that sexual dimorphism in dewlap color is likely not just driven by sexual selection, but by unique selection pressures acting on female anoles. This research raises new questions for achieving a more complete understanding of this popular model system.
