Use the following information to answer the next two questions. "Raft-riding green iguanas that
reached the Caribbean island of Anguilla in the wake of a hurricane have provided ecologists
with rare proof of one of the most debated theories of animal colonization of islands... The
iguanas were first spotted by fishermen on Anguilla on 4 October, coming ashore from a raft of
uprooted trees, some of which were more than 30 feet long. The best guess for the iguanas' origin
is the island of Guadeloupe, a few hundred miles to the southeast, where they occur naturally.
