Caribbean Anole Lizards
Remarkably, each Greater Antilles island (Cuba, Hispaniola, Jamaica, Puerto Rico) independently evolved the same set of ecomorphs.
Over 150 species of lizards that colonized Caribbean islands and radiated into distinct 'ecomorphs' - morphologically distinct forms occupying specific microhabitats: trunk-ground, trunk-crown, twig, grass-bush, crown-giant, and trunk specialists. Remarkably, each Greater Antilles island (Cuba, Hispaniola, Jamaica, Puerto Rico) independently evolved the same set of ecomorphs.
Anoles demonstrate modularity in limb proportions: hind limb length, forelimb length, toe pad size, and body length evolve largely independently, allowing rapid adaptation to different microhabitats. Phylogenetic studies show most diversification occurred early, shortly after colonization - the 'early burst' pattern.
Notable Traits of Caribbean Anole Lizards
- Ecomorph convergence across islands
- Modular limb evolution
- Predictable radiation patterns
