The Story of the Human Body: Evolution, Health, and Disease offers an evolutionary commentary on human health, arguing that we have failed to prevent preventable diseases because we fail to identify human evolution as a major factor. By definition, evolution is "the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth" (Lieberman, 19). Lieberman argues that evaluating why we get sick is essential for preventing and treating diseases. He proposes the mismatch hypothesis which argues that "the answer to why so many humans are now getting sick to once rare illnesses is that many of our body 's features were adaptive in environments for which we evolved but…show more content…
