Benefits of Integrating Fossil and Molecular Data Essay - 6

Benefits of Integrating Fossil and Molecular Data - Essay Example As explained by Neil Shubin, the occurrence of hiccups is as a result of the brain generating some electrical signals. Amphibian brains generate similar hiccups because they helped them to maintain a steady opening of their gills. Since we are products of evolution, our brains still generate similar hiccups. Recent research indicates that the level of obesity incidences is on the rise. This is as a result of the change in lifestyles and eating habits among individuals. On a closer look, Neil Shubin claims that the genes of our bodies were made to adapt to the rather active life of hunting and gathering as opposed to the relaxed modern living. Moreover, Shubin states that the evolution of the voice box has left many people vulnerable to breathing and swallowing problems. This is an indication that cells of living organisms are not fully adapted to their environment hence they are still evolving. In the analysis of the molecular structures, Shubin found out that somebody parts resemble d those of the early life forms. For example, the fins of early amphibians showed the clear resemblance to those of the human hands. Also, a fossil of a fish’s back-born indicated a resemblance to that of a human being. Neil Shubin further explained that our body cells function like bacteria and also our heads are organized in a similar manner to those of the jawless fish. This is a clear indication that human beings actually evolved from fish. Using the integration of fossil and molecular data, Shubin has been able to criticize the religious beliefs of the existence of a supreme being. Due to evolution, about 300 genes designed for the smell in human beings has been rendered useless. This prompted him to question the idea of the perfection of a Supreme Being claiming that if God is in existence, why would he create about 300 useless genes? Therefore, in the book ‘Your inner fish’,
