Natural World: Dragons Of The Galapagos

The iconic David Attenborough lends his distinguished tones to this fascinating look at the Galapogos Islands, the oldest of which is thought to have been formed by tectonic activity between five and ten million years ago. The youngest of the islands, Fernandina, is the site of the world's most active volcano, which last erupted in May 2005. It is also home to some remarkable examples of wildlife, especially the land and marine iguanas.
