The story of the human body is one of great advancement, and cultural progress, but are we living up to our evolutionary potential? Lieberman’s book asserts that we are not living up to this potential for a variety of reasons. One way that Lieberman addresses this issue is to speak about the evolution of the human species; from the very earliest human like primates, to the big brained Homo sapiens that are the sole species of human to exist today. A major advancement, in primitive humans was the transition from knuckle walking to becoming bi-pedal animals. He also mentions the transitions from hunter- gatherer culture to the agriculturally centered society, which began once humans started to gather together into more permanent …show more content…
The two topics covered in the most detail, and using the soundest methodology are: Evolutionary history, and the concept of mismatch diseases. Evolutionary biology had sound methodology and great detail because the writer has significant background information, as well as experience dealing in this concept. The idea of mismatch diseases however is a newer idea that he investigates thoroughly in the book. He uses in example, the current gene-environment interactions that are known to influence phenotypical expression of certain genes; such as the interaction that causes the expression of type II diabetes. The lower levels of exercise and our highly processed foods along with, gene predispositions have provided us with a society, or environment that our bodies are maladapted for, making us sick. Some of the strengths of this approach are that it is mainly empirically organized, providing the reader with facts, and tables, but this is limited because when using this method one can only provide facts, sometimes leaving out explanations due to the need for further information.
