Yet Darwin’s travels on the Beagle led him to witness events which called into question his early belief in divine providence. For example, while in South America, Darwin witnessed at first hand the terrible struggle for existence faced by the natives of Tierra del Fuego; he saw the devastating effects of an earthquake; and he began to grasp the magnitude of the staggering numbers of species that had become extinct – each of which, according to Paley, was providentially created and valued by God. We can see here the beginnings of the erosion of any belief in divine providence which would become characteristic of the later Darwin. If a crisis point was reached, it may have been through the death of Darwin’s daughter Annie in 1851, at the age of ten, which Darwin’s biographer James Moore sees as marking a watershed in Darwin’s religious convictions.28 Yet the origins of this development date from much earlier in his life.
