Its is pretty amazing what the nose can and how scent has affected our actions. Smell is an amzing aspect of daily life that people tend to underestimate. Though we can survive without it, it affects how we react or respond to things. Plus it makes food taste oh so much better. And even if there is no sense of smell, dolphins and whales found ways to adapt and find useful ways to make use of their nostrils. DNA is still quite the wonder, it continues to tell me new things i would have never expect. Especially how dna can control the sense of smell. Indeed DNA is an important aspect life, its role, functions, complicity, everything is mind-blowing. Overall this chapter was interesting, short, and straightforward.
