The book focused on the transmutations of species and explained, in detail, the mechanism that underlies evolutionary change. The economic focus of these new settlers was orchil, live tortoises, and tortoise oil that they sold to visiting whalers and sent to the mainland. The mere arrival of an organism to the Galapagos Islands is just one piece of the early survival puzzle. On a hot September day in 1835, Charles Darwin met his first giant tortoise on Chatham Island, part of the Galpagos archipelago.
