Ch. 7- Bodybuilding for dummies!

The first thing I noticed when I read this chapter was that there wasn't much talk about "my inner fish". I wondered after all this time of talking about fish now Shubin is finally going to start making some sense to the normal human. I enjoy how he relates the different parts of the body to other well known things such as bridges, sponges, and others of the sort. What really caught my attention was the tiny section about cartilage and the constant pounding of running. XD Most of this chapter was anatomical facts and geological development that I already knew so it was easy to understand with a little taste of freshmen biology class.

Shubin really put in to perspective the timeline of the earth's development when he compared it to the calendar year. It was shocking that life has only begun around June and the development of people occurred on the last day. I think he did a good job wrapping up the chapter by relating it back to geological development during the oxygen-plenty times and the blossoming of life. As for the theory of evolution, the timeline and body structure development are strong evidence that fit like a pearl into its oyster.
