Oliver Sacks on Your Inner Fish
Since the 1970 publication of Migraine, neurologist Oliver Sacks's unusual and fascinating case histories of
"differently brained" people and phenomena--a surgeon with Tourette's syndrome, a community of people born totally
colorblind, musical hallucinations, to name a few--have been marked by extraordinary compassion and humanity, focusing
on the patient as much as the condition. His books include The Man Who Mistook His Wife for a Hat, Awakenings (which
inspired the O-nominated film), and 2007's Musicophilia. He lives in New York City, where he is Professor of
Clinical Neurology at Columbia University.
Your Inner Fish is my favorite sort of book--an intelligent, exhilarating, and compelling scientific adventure
story, one which will change forever how you understand what it means to be human.
The field of evolutionary biology is just beginning an exciting new age of discovery, and Neil Shubin's research
expeditions around the world have redefined the way we now look at the origins of mammals, frogs, crocodiles, tetrapods,
and sarcopterygian fish--and thus the way we look at the descent of humankind. One of Shubin's groundbreaking
discoveries, only a year and a half ago, was the unearthing of a fish with elbows and a neck, a long-sought evolutionary
"missing link" between creatures of the sea and land-dwellers.
My own mother was a surgeon and a comparative anatomist, and she drummed it into me, and into all of her students, that
our own anatomy is unintelligible without a knowledge of its evolutionary origins and precursors. The human body becomes
infinitely fascinating with such knowledge, which Shubin provides here with grace and clarity. Your Inner Fish shows us
how, like the fish with elbows, we carry the whole history of evolution within our own bodies, and how the human genome
links us with the rest of life on earth.
Shubin is not only a distinguished scientist, but a wonderfully lucid and elegant writer; he is an irrepressibly
enthusiastic teacher whose humor and intelligence and spellbinding narrative make this book an absolute delight. Your
Inner Fish is not only a great read; it marks the debut of a science writer of the first rank.

A Note from Author Neil Shubin
This book grew out of an extraordinary circumstance in my life. On account of faculty departures, I ended up directing
the human anatomy course at the University of Chicago medical school. Anatomy is the course during which nervous
first-year medical students dissect human cadavers while learning the names and organization of most of the organs,
holes, nerves, and vessels in the body. This is their grand entrance to the world of medicine, a formative experience on
their path to becoming physicians. At first glance, you couldn't have imagined a worse candidate for the job of training
the next generation of doctors: I'm a fish paleontologist.
It turns out that being a paleontologist is a huge advantage in teaching human anatomy. Why? The best roads to human
bodies lie in the bodies of other animals. The simplest way to teach students the nerves in the human head is to show
them the state of affairs in sharks. The easiest road to their limbs lies in fish. Reptiles are a real help with the
structure of the brain. The reason is that the bodies of these creatures are simpler versions of ours.
During the summer of my second year leading the course, working in the Arctic, my colleagues and I discovered fossil
fish that gave us powerful new ins into the invasion of land by fish over 375 million years ago. That discovery and
my foray into teaching human anatomy led me to a profound connection. That connection became this book.
