Perhaps more so than any other place in the world, the fauna of the Galapagos are unique. Charles Darwin's observations of these unique animals, their
remarkable adaptation to a hostile environment, and the subtle variations between races of the same species living on different islands led directly
to his theory of natural selection.

The theory explains how the vast multitude of species on the Earth has evolved from a simple, singled-celled ancestor. The theory remains the single most
important one in biology. Thus we can look back at nearly five centuries of human contact with the Galapagos and say that, without a doubt, the most
important event in the human history of the Galapagos was Darwin's visit in 1835.

Even without Darwin, though, the tale of human contact with the Galapagos is a fascinating one, and the Enchanted Islands, as the early mariners called
them, have meant many things to many people from many lands.

The Galapagos Archipelago is situated 800 kilometres west of the Ecuadorian coast and lie directly on the equator. The archipelago encompasses over 50
islands of volcanic origin that are spread out over an area of about 4,500 square kilometres.

The volcanic Galapagos platform originated probably not more than 15 million years ago and the oldest island not more than 2.4 million years ago.
Volcanic eruptions still occur in the islands. Isla Fernandina and the Sierra Negra volcano on Isla Isabela have erupted within the past 10 years.

According to legend....the Inca Tupac Yupanqui set sail from the coast of Ecuador in the late 1400's with 20,000 men on balsa rafts. On his journey he
discovered and named two islands - Ava Chumbi (Outer Island) and Nina Chumbi (Fire Island). Some historians believe these islands were the Galapagos.
