6/8. William Smith 's Geological Map of England and Wales (1815). No one thought rocks were that important until they studied Smith's revolutionary, multi-coloured geological map of Britain. Years before Darwin, Smith overturned all the existing ideas about mineral prospecting, fossils and the origins of the Earth. Modern explorer Nicholas Crane 's investigation examines how Smith arrived at his ideas.
