Neil Shubin describes how he taught a human anatomy course at the University of Chicago, though his degree was in paleontology and his specialty was fish.
More specifically, every living organism comes from parental genetic information.
Every organism has parents—humans, mice, birds, plants, even bacteria! This law can also be extended to imply that we are not only just descendent of our parents, we are modified descendents. For example, a baby salamander is descended from its parents, but is not identical to them.
One of their sons was born with a genetic mutation that gave him a red rubber nose that squeaks. This son grows up and marries a lucky woman. He passes his mutated nose gene to his children, and they all have his red rubber nose that squeaks.
Now, suppose one of his offspring gets a mutation that causes him to have huge floppy feet.
When this mutation passes to the next generation, all of his children are like him: Go one generation further. Imagine that one of these kids…has another mutation: This example perfectly shows how descent with modification can be used to construct a family tree.
The key physical characteristics squeaky nose, floppy feet, and orange hair allow you to recognize the groupings or generations, and their pattern of descent.
However, moving in the opposite direction, where did the Bozo family lineage begin? Do the bozos stop at the original couple?
But where exactly did the bozos originate? Everyone agrees that their lineages can be traced back to ancient ancestors; however, the real question is: This is why decent with modification and family trees are important.
They allow us to trace back and hypothesize about ancient family relatives by analyzing derived characteristics of organisms. Here is a family tree to show the succession of characteristics in the Bozo family: This chapter includes many examples of disease that show how humans are products of a lengthy and convoluted evolutionary history.Need help with Chapter The Meaning of It All in Neil Shubin's Your Inner Fish?

When water flows around the fish, the neuromasts change shape and the hairs send an impulse to the fish’s brain that tells the fish how fast the water is moving.
Shubin focuses on the neuromast of trout, not explaining that trout also have an inner ear that handle the trout’s sense of hearing.
