In Daniel Liberman’s book, The Story of the Human Body: Evolution, Health, and Disease, he writes about the entire history of the human body and how it has evolved from our ancestors. His main purpose in writing this books is to not only educate and inform about the history of the evolution of the human body and its possible future, but his goal is to help push society to change the way they live. The main theme of The Story of the Human Body: Evolution, Health, and Disease is the same as Liberman’s purpose: to educate and inform about the evolutionary history of the human body and to incite society to change for the better. The book goes into great detail about our evolutionary ancestors including our way of walking, running, and throwing

The topic that are some of the most important to his argument are the mismatch diseases and the changes that should be made to further the survivability of humans. Mismatch diseases are diseases that occur simply because our body is not adapted to the changes in environment and accessibility to foods that weren’t available thousands of years ago (Liberman 2013). They occur due to a surfeit of energy (eating too much) and under use (not exercising enough). An example of the surfeit of energy is obesity, and an example of under use is …show more content…
However, it is not caused by one factor. Liberman and other scientists agree that obesity is caused by many different factors: diet, genes, the environment, and exercise (Liberman 2013). Due to the accessibility of foods, people are eating more and becoming less active. Also the foods that weren’t easily accessible to our hunter-gatherer ancestors, sugary foods, are in excess today. These sugary foods are necessary for energy production and were vital for our hunter gatherer ancestors who needed this energy to hunt and survive in their harsh environment (Liberman 2013). The human body made a necessary adaptation and started to crave the sugary foods that were needed to survive, and this craving is still present in humans today. However, due to the accessibility and the craving for these sugary foods, humans have become more obese. These findings are backed up with addition research from other scientists. Both Liberman and other scientists believe that “that consuming a diet high in fruit, vegetables, reduced-fat dairy, and whole grains and low in red and processed meat, fast food, and soda” will reduce the risk of obesity because these foods are closely related to what our hunter gatherer ancestors would have eaten (Newby PK et al., 2003). The environment also has an impact on obesity. The more people are stressed, the less they sleep which leads to
