A dog strolls by a giant tortoise on Santa Cruz Island, January 29, 2001. Santa Cruz is part of the Galapagos Islands and has a myriad of exotic species, including [iguanas, flightless cormorants, sea lions] and the famous Galapagos giant tortoises, a mix that inspired 19th century naturalist Darwin to devise his theory of evolution. The dog is an introduced animal to the archipelago. The Galapagos islands should make a full recovery from the oil spill that tarnished its sandy shores, a sign of hope for the hundreds of unique species there, scientists said.
