When Shubin got into the last couple pages of the chapter, he started to talk about how animals passed down genes that weren't functional anymore because we tend to favor sight over smell. I thought that that was pretty darn interesting. Who knew that our ancestors made it so we have functionless genes?
I really liked how he explained the two types of smelling genes: for water and for air. I've always wondered how fish can smell underwater, and how we can smell... above water. Ha. It was pretty cool.
