There is no doubt that Charles Darwin’s trip to the Galapagos Islands in the 1830s changed his life’s work. It  put him on the path to develop his game-changing theory of evolution. But Darwin’s observations were not isolated to one exploration. For years after his pivotal excursion, Darwin conducted unorthodox and innovative experiments to test his speculations, and he often did so in his own backyard.
