tthis chapter was interestinh. i never knew that we have over five thousand to ten thousand ordors that we can discriminate from. i thought that the nose was inportant but nevr thought is so important to us. also, that fishes have a nose like feature like us but they don't us it like us.
I was surprised when I found out about fishes having their nose's feature like ours but they use it differently than us. But I find it interesting how we can identify the different smells differently than anything else expect dogs. -Ashley Vargas
this chapter makes sense on an evolutionary level, i mean at some point in time there were creatures that had no eyes, so then how did they sense things? well they did it with the help of an acute sense of smell, to do everything from identify members of there own species for mating, or predetors, and i now think of smells as a kind of lock and key mechanism. like that for each smell receptor(the lock) there is a corresponding smell(the key) and each smell has its own unique receptor much in the way each lock has a specific key J.M.DiPietro
This chapter was (not to sound cliche) cool. I really want to do that experiment of finding the DNA. I sort of understood our sense of smell, but I would like to discuss it in class later on. However, one thing I found that caught my attention was on page 141 where Shubin states "how deeply embedded our sense of smell is inside of us.It is also very ancient." I never really thought about smelling before, and now that I see it is complex and so amazing, I think I have found a new appreciation for it. -Morgan Wininger
Shubin really makes this an interactive read, where he appeals to you and makes it all sound as though he's right there telling you all this. He gives examples, and even steps on how to find DNA in your own homes. He explains the link between DNA and genes to our sense of smell, which I have never thought about before. You learn that fish like lampreys and hagfish can extract odors from water the way we do with air. And even some many genes are rendered completely functionless by mutations. It's all so fascinating... -Loremae Mopera

I didnt kno that fish have an internal nostril and an external one. We only have two nostrils and we use them to breath in and out.
