History Beyond Timelines of Discovery

For the past week and a half, I have been listening to a lecture course on the history surrounding the theory of evolution, and it has left me contemplating how ideas, particularly ways of understanding, spread and change with the amount of information we have. Today, the concept of natural selection acting to produce changes in species over the course of generations strikes most people as logical and obvious, but Darwin spent many years working out that very logic after his famous visit to the Galapagos Islands. We, of course, have knowledge of genetics which had not yet been discovered at that time although experiments on inheritance of various traits were being conducted during Darwin's lifetime.
