Chapter 8:

I went out with my best friend today. While we were out, we went to Bath & Body Works to see the new additions of the B&BW collection. But, we tended to stick to the scents we liked. It was really ironic because my best friend and I were talking about how smelling a certain scent can bring memories flooding back. And Shubin's little blurb about how the perfume industry made alot of money was pretty ironic as well. 

Shubin's analogy of the lock-and-key our brains use to select certain smells really made the process of smelling easy to grasp. Although, the analogy to the chord struck an ever louder note (pun intended) with me because I play the guitar, which uses chords. The diagrams and example Shubin used to relate humans to animals did not disappoint. It was another example of the reasons why human evolution from animals is possible. It's slightly unnerving at how we as humans are so similar in many way to animals. But, it's also interesting. 

And that step-by-step DNA extraction at the beginning of the book? Well, let's just say that's really useful information for someone who has a microscope. (Yes, I have a microscope. No, I didnt buy it. It was a gift.. I have a telescope too.. haha.)
