Neil Shubin is one of the discoverers of Tiktaalik, one of the 'missing links' between fish and land animals. This book is an engaging mix of personal anecdote, and an illustration of how anatomical features in fish have parallels in humans. It also help to explain some of the peculiarities of the way parts of our anatomies are arranged, and why we fall victim to diseases such as obesity, heart disease and hernias. The whole is clear and readable, and you won't need a background in science to understand and enjoy it.
