We are all the product of our surroundings, and our characteristics and interests are built from those we surround ourselves with. Charles Darwin’s grandfather was perhaps one of the most influential people in his life. Being exposed to Erasmus’s literature, especially those on plant evolution must have sparked his earliest interests in biology, and his fascination on biological change. Although Charles had never met his grandfather, the lineage is clear when understanding they both shared a mutual interest in evolution. It is interesting to note that Butler’s criticism of Darwin’s work illustrates a lack of recognition on the part of his grandfather, and this blatantly seen in the literature. Erasmus had many interests and hobbies, and with many of them combined what surfaced were poems on evolution. Multiple methods of studies used by Erasmus were followed forth by Charles and the many different subjects he was clearly interested in. Erasmus was a very smart man, and as such he had come up with many inventions in his lifetime. This ambition towards making new things, and new discoveries was perhaps a genetic precursor to what was in store for the future generations of the Darwin family.
