'Your Inner Fish' tells the history of the human body and gives answers to some of the questions that only evolution can. Why do we look the way we do? Why are we able to do all the different things we do? And, finally, why do we fall ill in the way that we do? Neil Shubin draws on a genetic research to show the impact the 3.5 billion year history of life has had on our bodies. He takes readers on a journey and allows us to discover the deep connection to nature in our own bodies.
