The document discusses a speciation event involving raft-riding green iguanas that reached Anguilla after a hurricane. This occurrence serves as evidence supporting theories of animal colonization of islands, particularly suggesting their origin from Guadeloupe. The arrival of these iguanas illustrates a notable example of speciational dynamics following environmental events.

(2) 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. (Lawrence, 1998, Nature)
