Background Information Throughout the Caribbean Islands there is a species of anole lizards that throughout time have evolved into different sub species. The phylogenetic trees show this type of evolution because similar traits are based on environments, and not location/species type. Videos Note. It also shows the techniques used by scientists to study these lizards.
