Your Inner Fish Book Review

1569 Words7 Pages

As a secular person who takes an interest in science, I have always been fascinated by the academic field of evolutionary biology. Because of this, it should come as no surprise to anyone that the book I chose to review is entitled Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body. Written by Neil Shubin, this piece aims to outline the origins of humanity, as well as present a plethora of compelling pieces of evidence for the theory of evolution. He does this by reviewing scientific discoveries in areas of comparative anatomy, genetics, and the examination of fossils. Interestingly enough, he also integrates some of the most basic senses that we possess, such as sight and smell. If read properly with an open mind, …show more content…

The author explains how to extract DNA from something using household goods that one can find in their kitchen, which is exactly what we did using strawberries.

According to the author, cetaceans (marine mammals) have lost their senses of smell. While one would assume that their bodies would just readjust and revert back to having a genome that promoted effective water-based genes, that isn't the reality. They cannot smell at all! Interestingly enough, a lot of these same genes used for the sense of smell are present in a plethora of other animals. Although some interesting points such as this one were made in this chapter, I feel that this was the weakest chapter out of all of them. He doesn't seem to articulate himself as well as he did in the previous chapters, and it seems like an outlier compared to the rest of the book. I think the root of the reader's potential confusion for this chapter could be the fact that not all of us are as educated on the field of genetics as he is, and even though he attempted to explain it, it wasn't as thorough as it probably should have
