Show Me Your Teeth

Our teeth contain a high concentration of Hydroxyapatite, well, would the "apatite" part have anything to do with appetite. Also, does tritheledont's name have any correlation with the french word dents (trithele-dont) for teeth. I'm just wondering.
Although this chapter contained an abundant amount of boring biographical commentary, I found the idea of teeth being the blueprint for the rest of our complex internal organs interesting. "Once the process that makes teeth came into being, it was modified to make diverse kinds of organs that lie within skin" (79). The idea that our gall bladder owes it's existence to our teeth is extremely absorbing. In addition, man kind can simpy look at a bird or a fish and say that they have one thing in common with it, if not more things in common. Shubin does an outstanding job in explaining teeth. However, it would have been better if Shubin went into detail as to why Ostracoderms needed teeth to create an external shell, rather than to have divulged into the details of his first expedition. I enjoyed it when Shubin gave the reader some context on the discovery of conodonts-would the name for conodonts originate from cono-cone shaped and dont(dent)-teeth, this is mere speculation-and how scientist soon found these conodonts inside the mouths of a conodont(named for the teeth found within it). Well let's just say that the names for these creatures is more interesting to me than the importance of them in history itself.
