In the article What Makes Us Different, Katherine Pollard examines the comparisons of the genomes of chimpanzees and humans. Pollard’s goal was to understand the sequences of DNA bases and letters in the genome as well as the understanding of how the human genome was evolved through years. Pollard had begun on finding DNA sequences that set chimps and humans apart after having some evidence she revealed that human DNA blueprints are 99 percent identical to our closest living relative chimpanzees. Furthermore, she discovered that the three billion letters that made up the human genome approximately fifteen million of them has been changed over time from the time when humans and chimps origins separated. According to the evolutionary theory,
