Сведения о жизни Дарвина я в основном черпал в: Ronald W. Clark, The Survival of Charles Darwin: A Biography of a Man and an Idea (New York: Random House, 1984); Adrian Desmond, James Moore, Janet Browne, Charles Darwin (Oxford: Oxford University Press, 2007); и Peter J. Bowler, Charles Darwin: The Man and His Influence (Cambridge, U.K.: Cambridge University Press, 1990).
