In 1979, the Galapagos Islands was one of the earliest World Heritage Sites to be selected by UNESCO (United Nations Educational, Scientific and Cultural Organization), a designation intended to protect and preserve sites of cultural and natural heritage around the world. Today, there are over a thousand World Heritage Sites and the Galapagos Islands are one of the most widely valued. The biology of the Galapagos Islands has arguably been studied more than any other archipelago in the world. Charles Darwin visited the Galapagos Islands in 1835 and spent several decades studying the flora and fauna of the islands. His observations and collections contributed to the inception of Darwin's theory of evolution by natural selection, one of the most important ideas in all of science. The new Republic of Ecuador took the islands from Spanish ownership in 1832, and subsequently gave them official Spanish names. The islands are located in the eastern Pacific Ocean, 605 miles (973 km) off the west coast of South America and consist of 18 main islands and 3 smaller islands. In this richly illustrated tour of the Galapagos, world renowned photographer and naturalist Wayne Lynch captures the unique wildlife living here, including the Galapagos tortoise, the marine iguana, the flightless cormorant, the blue-footed boobie and the magnificent frigatebird.
