Chapter Five: Getting Ahead

Okay, the beginning of this chapter sounds like a horror story! Here's a guy in the middle of the night holding a human head in both hands surrounded by other dead bodies... and all for a final??! An interesting fact, I didn't know the bone plates that cover our brain are separated until the age of two. The arch idea was good, although I did have to reread it a few times, in explaining a simplistic technique to understand our brain. As noted as early as the 1800's the vertebrae holds our brain and sense organs it is what segments our body. It was neat to learn that the segmentation of our head can only be seen among a developing embryo. As one might have guessed by being able to understand the brain and its arch patterns one can also note the casue of certain birth defects found amongst children. Another engaging thought was that the upper bone in a shark's jaw can also be found as the stapes in a human's ear. Backing up the continuing thought that all organisms evolved from similar products and it is with time these certain organisms develop purposes and uses for the things they are given . For example, the evolution of a lever system of bones is used in both a shark and human however for very diverse purposes.
