Puerto Rico, Cuba, Jamaica, and Hispaniola have species of anole lizards with distinct body types, including the grass lizards, which have long tails; the canopy lizards, which have large toe pads; and the twig lizards, which have short legs. Anole species with each of these three body types exist on each of the:

four islands.

Explanation:

Anole lizards includes different types of lizards such as the canopy lizards, the grass lizards and the twig lizards and are found in Puerto Rico, Cuba, Jamaica, and Hispaniola.

Anole species with each of these three body types exist on each of the four islands because of interisland migration  events.

The anole species share common ancestor with each other in comparison to other lizard species, interisland migration  events allowed anole species  to get evolved by natural selection process in different islands including Puerto Rico, Cuba, Jamaica, and Hispaniola.

Hence, the correct answer is four islands.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
