Chapter EIGHT.

When Shubin said that DNA is so easy to extract that you could do it in your kitchen, I thought “yeah in some genius scientist’s kitchen”. But when he started explaining it, it wasn’t complicated at all.

It was amazing to learn that “Our sense of smell allows us to discriminate among five thousand to ten thousand odors”. I never even though that my nose could do that!

When Shubin was explaining how we can detect a smell the analogy of a chord was brilliant. It made things more simple and easy to understand. (:

I never really thought of “our sense of smell being housed inside our skull”. But then when I saw the pictures on pg 143 I was kind of surprised.

Again, through the smell, Shubin relates us to fish; which I had NEVER thought of.

I liked learning about how dolphins and whales contribute to the question of why we have so many odor genes if many of them are useless. They use their smell genes not to smell, but to breathe.

I think it's pretty cool that we use our vision more than our smell.

So in all, as other students have said, this chapter was to the point; short; and a fun, easy read (:
