 Hybridization between different anole species has rarely been documented.In contrast to this, anoles can change rapidly in response to changes and they are one of the few known examples of "visible evolution" (i.e., where changes happen at a speed where they can be observed within a human lifetime), together with groups like stickleback fish, guppies and "Peromyscus" beach mice.In studies of brown anoles introduced to Florida it has been seen that they can become longer-legged in a single generation when living with the predatory, ground-living northern curly-tailed lizard (shorter-legged anoles are slower and easier to catch for the curly-tailed lizard).
