Darwin is another example, what he saw and wrote in his private journals, was left out of his The Origin of Species.
Darwin Puzzles Over the Evidence
In his book The Origin of Species Darwin wrote, "The extinction of species has been involved in the most gratuitous mystery.
No one can have marveled more than I have at the extinction of species" (Charles Darwin, The Origin of Species, New York: Collier, 1962, p. 341).
Darwin was referring to his five-year cruise as amateur naturalist aboard the H.M.S. Beagle. In his notes he revealed WHY he and the paleontologists of today, "are puzzled by the record of catastrophic death found in the rocks."
"What then, has exterminated so many species and whole genera?" Darwin asked in astonishment. "The mind at first is irresistibly hurried into the belief of some great catastrophe; but thus to destroy animals, both large and small, in Southern Patagonia, in Brazil, on the Cordillera of Peru, in North America up to Behring's [Bering's] Straits, WE MUST SHAKE THE ENTIRE FRAMEWORK OF THE GLOBE" (Charles Darwin, Journal of Researches into the Natural History and Geology of the Countries Visited During the Voyage of H.M.S. Beagle Round the World, citation under date of January 9, 1834).
What he wrote in his notes never reached the book he wrote years later. His patron Lyell, the father of Uniformitarianism, wouldn't have approved...
Think about the time it took Monte Verde in Chili to get a somewhat approval.
He can find many fans of his incredulity at the shaking of the entire globe, particularly among those who profess hatred for his work, without knowing what’s really in it. :’) Thanks Fred Nerks, nice excerpt!
