"This work has been called the most important scientific book ever. A stunning claim, but certainly Charles Lyell's Principles of Geology, published in 1830, shook prevailing views of how Earth had been formed. His book was an attack on the common belief among geologists and other Christians that unique catastrophes or supernatural events -- such as Noah's flood -- shaped Earth's surface. Lyell argued that the formation of Earth's crust took place through countless smaller changes occurring over long periods of time, all according to known natural laws. His proposal was that the forces shaping the planet have operated continuously throughout its history. He also wrongly assumed that these causes must have acted only with the same intensities now observed, which would rule out asteroid impacts and the like. Darwin read Lyell's landmark text while on the Voyage of the Beagle, and was much inspired by it. His own experiences during the voyage backed up Lyell's theories of how the shifting crust of the Earth was one of these long-acting, gradual, shaping forces".
