Product Description

Your Inner Fish tells the extraordinary 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 the latest genetic research and his huge experience as an expeditionary paleontologist to show the incredible impact the 3.5 billion year history of life has had on our bodies. He takes readers on a fascinating, unexpected journey and allows us to discover the deep connection to nature in our own bodies.

a truly great book!
(from my amazon.com review)

This is the most enjoyable book I've read on evolution since Gould's fine Wonderful Life. Shubin not only combines great skills in paleontology and anatomy with an insatiable curiosity, but he also has a rare gift at writing as well. The book looks at aspects of human anatomy and senses--hands, smell, hearing, vision, etc--and traces them back--way back! Some of this, of course, has been done before, but Shubin writes with a flair, a clarity, and a precision that brings it all into a new focus. There is also an emphasis on DNA, in particular recent DNA experiments that combined with the paleontology and anatomy makes a very compelling case.

Shubin starts off with the search for a link between fish and land animals that took him to the Canadian Arctic and culminated in the discovery of Tiktaalik--a fish with a flattened head and flippers that made it look rather like a very primitive alligator in ways. The author then shows the evolution of necks and limbs. He does the same with some of the organs such as smell and vision, and shows their evolution as well.

The book is perhaps at its best in its discussion of the role of DNA in evolution. It is now known that it is possible to turn on a gene that is responsible for the development of an eye, for example. So you can create a fruitfly with an eye almost anywhere you want--such as on a leg--and many of these are functional, although in a primitive way. But it gets even more interesting. Suppose you take a gene from a mouse that controls the development of an eye, and implant it into a fruitfly, what happens? You get a fruitfly eye, not a mouse eye. This says a lot about the basic building blocks of life.

The book does have one major flaw. At 200 pages it's way too short! If the writing were dry or stiff, 200 pages would be sufficient, but with Shubin's thoroughly enjoyable writing and choice of subjects, I would have preferred 600 pages.

Wonderful Witty and Informative
I cant begin to describe how good this book is, ive actually cleaned out my local waterstones of all 4 copies to give friends and have 3 more on order- birthdays sorted for a while!
Rather than look at human body/evolution as two seperate issues, or for that matter get bogged down in too much genetics (hox genes give me a headache) it strips the body down into specific parts and then tries to show how that part has developed, what previous uses it had, and why we have it today. It never gets too scientific or jargony but its still based on proper science and evidence- i wouldnt say a 10 year old could read it but some of my friends are most definately not "readers" and they enjoyed it.
A MUST BUY!!

Hands, hyoids and . . . hiccups??
What a pity there is no Nobel for palaeontology. Some sort of award should be given to Neil Shubin for finding "Tiktaalik" in the Canadian Arctic. It wasn't a chance find - he relates the detailed planning steps leading to its discovery. An extra ribbon should grace the medal for explaining that fossil's significance in this book. There have been recent accounts on the evolutionary path of animals emerging from the sea to take up the role of landlubber. Carl Zimmer's "At The Water's Edge" and Jenny Clack's "Gaining Ground" are examples. Both preceded the "Tiktaalik" find, but more to the point here is that while both are excellent writers, Shubin demonstrates communicative skills bordering on the superb. This is truly a book for everybody. Especially if you want to know why you develop hiccups.

A great fuss was made over the "Tiktaalik" discovery. What is its significance? For starters, it was flat-headed ["So what? I know lots of people who are flat . . ."]. While we may consider flat heads in derogatory terms, for life emerging from the sea, it was a vital step. That the head could move independent of the rest of the body was even more significant. Fish cannot do this, and except for bottom dwellers, don't have flat heads. Further, "Tiktaalik's" eye structure gave it forward vision. In a creature 375 million years old, these characteristics are significant. They offer clues to how you and I are put together and why. Shubin offers a meaningful example of this when he showed "Tiktaalik" to his daughter's preschool class and they declared it to be both fish and reptile - which is the key to the value of his work here.

Land dwelling, Shubin reminds us, requires major changes in body plan. Instead of fins propelling the body through the water, limbs capable of supporting that body must develop. Those limbs must have flexible contact points, leading to the formation of fingers from fin bones. Lifting the body reformed the bones' arrangement leading to our wrist and hand structures. Air breathing shifts the location of oxygen-capturing equipment and distribution. Predation techniques change, which might render some bones superfluous. The author's description of how the former jaw bones of fish relocated over time to become the delicate transmitters of sound in our inner ears. Making sound turns out to be derived from other fish. The ancestors of sharks left a string of arches as part of our bodybuilding mechanisms. One of those arches nestles in your throat as the hyoid bone, essential in making speech. Another of those arches evolved into the diaphragm separating our lungs from other internal organs. Hiccuping, Shubin says, "has its roots in fish and tadpoles" because the pattern set in our brain that controls breathing has been "jury-rigged" in the steps to becoming human. In fish, the distance from the brain to the gills is short, but in mammals, the convoluted path those nerves take allows for signal disruptions - hence, hiccups.

Shubin spends much time explaining the development of embryo studies. Watching the progress of a fertilised egg in becoming a finished organism gave researchers insight in how to look for signs of how today's life is assembled. In Freshman Biology, we are still told of "ontology recapitulates phylogeny" - the idea that a human embryo goes through fish, reptile and mammal stages during development. Karl von Baer had already discovered this was incorrect, but it took modern genetic analysis to overturn Ernst Haekel's enduring axiom. Embryos, von Baer observed, form in triple layers, and depending on the signals from the genome, enable one of the layers to begin dominating to produce the appropriate body plan. Shubin uses these studies to further explain the rise in understanding leading to the appropriate HOX genes triggering the chosen layer. As he notes, his work area is braced by two seemingly irrelevant facilities - a fossil preparation facility at one side, and a genetics laboratory at the other. This book brings the two disciplines together with seamless effectiveness. Graced with some photographs, but many fine line drawings to enhance the text, the book is a prize addition to everybody's library. [stephen a. haines - Ottawa, Canada]
