"By observing the special biology and geology of isolated islands during the cruise of the 'Beagle,' Darwin's reflective mind saw, in the struggle for existence, that favorable variations would tend to help survival, with the resulting formation of new species. Fossil remains and the extinction of species, such as the dodo and solitaire birds, further supported such a position. This, the most important single work in science, brought man to his true place in nature" (Dibner).
