chapter 8

So I'm really tempted to try and separate DNA from something. I mean it made it sound pretty simple and really cool to see. I'm not so sure what meat tenderizer is though, or what my mom will think if she sees me blending up a bunch of random stuff, which I'm guessing doesn't look to pretty all mixed together. Still, I kind of want to see that goopy white ball.
I found it pretty interesting how our sense of smell is so precise. The analogy of smell to music reminded me of a very random discussion we had in chemistry of a lady who could smell music. That's just so amazing to me! It must be horrible listening to the radio though, a song goes on you don't like and all of a sudden there's a bad odor in the car.
The diagrams in the chapter reminded me of the pictures of monkeys turning into humans, except this time it was an eel like fish transforming to a human. Does the diagram mean we evolved in that order or we all just have the ability to smell in common? It feels weird to think i descended from a rat.
This chapter was a lot less technical then the others were and really reminded me of an episode of the magic school bus. I learned a lot of my biology from that show growing up. It's pretty cool how we can find out so much of our past just from the ability to smell. I'm a little confused from the part on dolphins and whales. Can they smell or did they give that up to breath? The trade off for sight instead of smell was interesting and does it mean blind people have more odor genes activated?
