Who or what is responsible for the occurrence of life on earth, and possibly many other planets, is a question that has plagued humanity for thousands of years. Once life was present on the planet, scientists largely agree that natural selection, the theory presented by Charles Darwin, took place allowing the hundreds of various species to emerge from one common ancestor known as the last universal common ancestor (LUCA) (Christian, Brown & Benjamin 2013, p. 57). Theories of how life actually came into being include; life began with a spark from electricity, which can generate the amino acids and sugars necessary for life to form (Choi, 2011); RNA provides the missing link between non-life chemicals and living cells (Emspak, 2015); or perhaps the more favored theory of Chemical Evolution, which states “the individual molecules that form the basis of life also likely developed in response to natural selection” (Moskowitz, 2012). By gaining an understanding and examining evidence associated with each of these three theories it becomes clear that the most logical and truthful of the three is the theory of Chemical Evolution. Before delving directly into the first theory, one must understand Darwin’s theory of natural selection because it is a theory that the majority of scientists take to be true. The scientific community agrees on natural selection because the evidence for it is provable and indeed happening before their very eyes. DNA molecules copy themselves almost…
