Essential Question: Function of smell. How it is helpful?
Shubin opens this chapter with an experiment and I find it interesting experiment. I really liked this quote: “DNA is an extraordinarily powerful window into life’s history and the formation of bodies and organs. ITs role is particularly important where the fossil record is silent. Large parts of bodies — soft tissues, for example — simply do not fossilize readily. In these cases, the DNA record is all we have.” This is the true fact and one of the interesting things this chapter.
Shubin was talking about how we can differentiate many different odor because of sense of smell. Well, our brain has stored different molecules and might associate with those memories when you smell something. Sense of smell is located near the part of the brain where memory is associated with.
Shubin also talks about some records of some major evolutionary transitions, such as the water-to-land move 365 million years ago. I think these are key factors of this chapter
