What is the author's tone in the nonfiction book, Your Inner Fish?

The overall tone of “Your Inner Fish” is informative and oftentimes technical in nature. However, Shubin brings a lightness and humor to much of his narrative which gives the reader a break from the intensity of the material. Shubin explains how the body works down to the molecular level which is quite heavy reading. He makes the connections between fossils that are literally millions and even billions of years old with man. Making the connection is a circuitous route and exhaustive for those readers who are not paleontologists. By providing some humorous anecdotes and witty narrative he lessens the unavoidable complexity and intensity of the material.
