Chapters 8-11

In chapter 8, Shubin talks about human and animal's scent and how it is like a baffle. For example, every chemical we scent has an exclusive shape and synthetic attributes. In our smelling organ, we have this enzyme in the cells of our nose that matches the chemical completely. However, what I found interesting as I was reading through this chapter was the behavior of the animals. Fish can only sense the proteins in the water, mammals can sense the proteins in air, while amphibians can sense the proteins underwater or in air. This was quite interesting to me because I never knew that in the inner part of our nose can recognize approximately 10,000 extraordinary fragrance. Overall, this chapter was quite inspirational.

In chapter 9, Shubin talks about the vision and how we can see. The brain interprets and annotates the pattern of nerve authorizations into what we think of as a representation. One part that caught my attention were the fruit flies and how they were born with eyes on their legs which allows them to act in response to light and that they're not linked to the nervous system. As I read about fruit flies and about their special effects, it was pretty amazing.

In chapter 10, Shubin talks about ears. I really like the fact how Shubin provides examples of hearing regarding of talking about sharks. For example, when you spot a shark eating another type of fish smaller than them, the shark probably heard and sensed the water flowing as the little fish swam by. Therefore, a shark can sense the fish like as if an individual can sense the changes and alterations around the surroundings.

In chapter 11, like what the title says, this chapter basically covers up all of the significance and the importance from the rest of the book. I learned more about the particular aspects of evolution. Because I already knew some basic evolution belief or theory, learning about how us, as an individual human being and how we are specifically related to a certain animal quite amazes me and helped me get a better understanding of the evolution theory. Indeed, I really enjoyed reading this scientific, adventurous book which was very inspirational and educational, yet entertaining.
