This creates a beautifully written short story with a series of examples of how human biology is linked to its evolutionary past.
The book presents an historical account of what we currently call human and reveals how the human organism is an accumulation of successful biological solutions to environmental problems that were faced by organisms that preceded us.
Shubin is an articulate writer with the accuracy of an anatomist, the perseverance of a paleontologist and the humor of a comedian. While looking for a fish with a neck and elbows in a hole in the Arctic permafrost, Shubin finds a way to teach human anatomy to medical students, explain evolutionary relationships and show the importance of learning where we came from.
Shubin begins with his expeditions searching for fossil fish in the hills of Pennsylvania and the Arctic permafrost. He recounts his initial modest successes, and some failures, with a sense of humor and adventure. These expeditions eventually lead to the incredible discovery of an elbowed fish with a neck.
He continues with the insights he gained about human anatomy from looking at the anatomy of this fish that lived million years ago. Each chapter builds on this theme as he links the structures, physiology and genes in one organism to another and demonstrates how these characteristics relate to human biology and disease.
He called his elbowed fossil fish Tiktaalik, the Inuit word for large freshwater fish. Tiktaalik symbolizes how nature is connected as a fish that lived at the interface of two worlds water and land. While ancient jawless fish have relatively few chemical receptors in their brains, modern fish, amphibians, reptiles, and mammals each add on more receptors until reaching the incredible number of smells that the average mammal can detect.
Yet though humans have the same receptors for smell that other mammals have, some have been rendered useless by generations of mutations because we are more dependent on our sense of sight.
Moving on to vision, fossils of eyes are rarely found because they are soft tissue that is not usually preserved.
So scientists look to the vast range of eye types found in modern organisms. The human eye uses the same basic light gathering molecules called opsins that are found in invertebrates. The two types of eyes in vertebrates and invertebrates are made up of the same components.
There is even a worm that has both kinds of eyes.
After studying flies born with a mutation that caused them not to have eyes, scientists realized that the same gene controls eye production in almost all animals. In Chapter Ten, Shubin examines the human ear, which gets far more complicated on the inside than it seems on the outside. Two of the three human ear bones seem to have developed bones that form part of the jaw in reptiles and fish.
In Tiktaalik , Shubin can see the upper jaw support bone that became the ear bone in reptiles after the transition to land animals.
The inner ear is very connected to the eyes, providing humans with a sense of balance. The antecedent to that organ is found in the neuromasts of fish, who need a way to feel the current going past their bodies.
This connection between eyes and ears is upheld by genetic research that has identified two genes responsible for forming the inner ear—which are also partly involved in the eyes of primitive animals like jellyfish. Putting all of this together, Shubin goes back over all the ways that the human body carries the history of life on Earth in its various anatomical structures. The deep similarities among all animals then become more and more unique as subsets of animals that have the most in common show exactly when in the history of life groups such as reptiles, amphibians, mammals, and finally humans became distinct from one another.
The biological record also gives hints about why certain illnesses and injuries are prevalent in humans. Knee injuries, obesity, hiccups, hernias, and mitochondrial diseases all point to the ways that human bodies repurpose body systems from other animals. Shubin ends the book looking towards the future, as scientists continue to unravel where the human body came from, and where it might develop in the future. Sign In Sign Up. Plot Summary.
