Charles Darwin

About this figure

Charles Darwin (1809–1882) was an English naturalist whose theory of evolution by natural selection reshaped how humanity understands its own origins and its place among other living things. Trained first for medicine at Edinburgh and then for the clergy at Cambridge, he found his true calling when he was offered, at twenty-two, an unpaid post as naturalist aboard HMS Beagle on a five-year surveying voyage around South America and the Pacific. The specimens, fossils, and observations he gathered on that trip -- particularly the finches and tortoises of the Galápagos Islands and the fossil remains of giant extinct mammals in Patagonia -- gave him the raw material for a theory he would spend the next two decades quietly testing and refining before publishing it.

That theory, natural selection, held that small variations arise in every generation of a population, that individuals with variations suited to their environment survive and reproduce more successfully than others, and that over immense stretches of time this simple mechanical process is sufficient to produce the diversity and apparent design of the living world, without recourse to a guiding hand. Darwin delayed publishing for years, in part from caution and in part from an awareness of how the idea would be received, until a letter from the naturalist Alfred Russel Wallace, who had independently arrived at a similar theory, prompted the two men's ideas to be presented jointly to the Linnean Society in 1858. Darwin's own account followed the next year in On the Origin of Species (1859), a book written for a general audience and argued, chapter by chapter, from evidence he had spent a lifetime collecting: pigeon breeding, geographic distribution of species, the fossil record, and the structure of organs like the eye that critics thought could not have evolved gradually.

Darwin extended the argument to human beings in The Descent of Man (1871), controversially proposing that people, too, were products of evolution and shared common ancestry with other primates, and in The Expression of the Emotions in Man and Animals (1872) argued that emotional expression itself had evolutionary origins shared across species. He was, throughout his life, a meticulous and patient observer of the natural world in even its humblest corners: his final book, The Formation of Vegetable Mould through the Action of Worms (1881), was a study of how earthworms slowly reshape entire landscapes. His earlier travel narrative, The Voyage of the Beagle, remains a vivid firsthand record of the journey that started it all, and his posthumously published Autobiography offers a frank, occasionally self-deprecating account of his own intellectual development, his loss of religious faith, and his family life at Down House in Kent, where he lived for four decades with his wife and cousin Emma Wedgwood and worked in relative seclusion, chronically ill for much of his adult life, until his death in 1882. He is buried in Westminster Abbey, near Isaac Newton.
