''The Voyage of the Beagle'' is Charles Darwin's account of the momentous voyage which set in motion the current of intellectual events leading to ''The Origin of Species''. This ''Penguin Classics'' edition is edited with an introduction and notes by Janet Brown and Michael Neve. When HMS Beagle sailed out of Devonport on 27 December 1831, Charles Darwin was twenty-two and setting off on the voyage of a lifetime. His journal, here reprinted in a shortened form, shows a naturalist making patient observations concerning geology, natural history, people, places and events. Volcanoes in the Galapagos, the Gossamer spider of Patagonia and the Australasian coral reefs - all are to be found in these extraordinary writings. The insights made here were to set in motion the intellectual currents that led to the theory of evolution, and the most controversial book of the ''Victorian age: The Origin of Species''. This volume reprints Charles Darwin's journal in a shortened form.In their introduction Janet Brown and Michael Neve provide a background to Darwin's thought and work, and this edition also includes notes, maps, appendices and an essay on scientific geology and the Bible by Robert FitzRoy, Darwin's friend and Captain of the Beagle. Charles Darwin (1809-82), a Victorian scientist and naturalist, has become one of the most famous figures of science to date. The advent of ''On the Origin of Species'' by means of natural selection in 1859 challenged and contradicted all contemporary biological and religious beliefs. If you enjoyed ''The Voyage of the Beagle'', you might enjoy Darwin's ''On the Origin of Species'', also available in ''Penguin Classics''.
