This book, otherwise known as On the Origin of Species by Means of Natural Selectionwas written by Charles Darwin following his transcontinental Beagle expedition to further his geological and biological research. On this expedition, he visited various islands including the Galapagos Islands, Tahiti, and Australia. On these trips, Darwin analyzed his findings and wrote On the Origin of Species to publishhis new research regarding evolution and natural selection. This book essentially changed the face of science in the nineteenth century, as evolution went against the popular, powerful catholic religion of the time. However, the new emphasis on science being absolute aided in Darwin’s ability to put out his findings and change the way that humans see themselves in relation to the rest of nature. After this, it was apparent that humans were not the center of the environment in which they live. This is similar to the paradigm shift seen when Galileo shared his findings that the earth rotates around the sun. His findings included the evolution of different finches and their beaks depending on their locations.
