The Origin of Species: Lizards in an Evolutionary Tree This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.
