““CONTRARY TO THE COMMON ASSUMPTION , Charles Darwin did not originate the idea of evolution. By the middle of the nineteenth century, the mere fact of evolution had been around for a long time, and most thinkers of the time were perfectly content to leave it at that. The absence of a theory to explain evolutionary change didn’t trouble them, wasn’t experienced as a pressure, as it was by Darwin. He knew there had to be some intelligible mechanism or dynamic that would account for it, and this is what he went looking for—with well-known results. In his Origin of Species, he wasn’t announcing the fact of evolution, he was trying to make sense of that fact.””
