Exercise 3


The Galapagos Islands

Located  near the equator, the Galapagos Islands are a group of volcanic islands off the coast of Ecuador.Discovered by Spanish colonists in 1535, and first shown  on maps in about 1570, the islands were rarely visited,being a haven for pirates. Having  developed their own specializations and escaped the attentions of predators common elsewhere, the Galapagos species had become unique and afraid of people. Passing ships hunted seals and giant tortoises. Once captured the tortoises were kept alive on ships for long periods and later eaten. After facing  near extinction, few of these creatures remain today.Visited by the naturalist Charles Darwin in 1835, the islands  still have a close association with Darwinian theory, being the home to many species isolated from the mainland.
Finding later that birds which differed from island to island were in fact the same species.Now  protected as part of a national park, the islands are popular with eco tourists.
