The competition between invasive Cuban brown anoles and crested anoles from Puerto Rico is a real-time study of rapid adaptation in species facing new environmental pressures.
Research led by Georgia Tech's James Stroud highlights how brown anoles are exhibiting rapid behavioral and physical changes due to their interactions with crested anoles for survival.
Stroud notes that the anoles evolved completely independently over millions of years, making their competition an unprecedented study of convergence and adaptation under duress.
With the opportunity to observe, Stroud's team found that the brown anoles are adapting at a pace that challenges previous notions about evolutionary speed in response to competition.
