We should use our differences for the better.....

"We're all modified sharks-or, worse, there is a lawyer inside each of us" (90).
The statement above made me contemplate the nature of human beings. Although we start off almost identically with sharks (and for that matter, almost every other specious of animals), the human brain has evolved so that we are highly capable of thought, emotion, and reason. Shubin does his job as a biologist/scientist to show how humans biologically came about and the resemblence between humans and sharks/fishes, we-as readers, as highly capable beings full of potential, as AP/IB students, should be able to seperate ourselves from sharks/fish.
Anatomically, we might be similar as vicious sharks, but that doesn't mean that we should let that affect our humanity. The world isn't a kill or be killed world that only beasts live in. Our brains are way to developed and intricate to resort to that. However, it is impossible to study humanity without bloody wars and acts of inhumanity.
On a postive note, our intelligence allows us to have some humility. For example, throughout the chapters, Shubin constantly explains how humans are related to other animals, even fish. Our hands,arms, legs and even heads are alike. I think that everybody should read this chapter to understand that people aren't structually much different from animals.
However, we are different intellectually and since we have much more impact on the world, we should use that intelligence to change the world for the better.
