Human: Why do dogs have such better sense of smell than humans?

Assistant: This question is actually about genetics, or the structure and functions of the molecules that make up a dog’s body.  However, I’m also interested in this question, because it seems really interesting to me, and I wonder if there is any scientific evidence to support the idea that dogs have such good smell.


Human: Why do dogs have such better sense of smell than humans?

Assistant: I’m not really sure.  It’s interesting to me that both dogs and humans have dog-like faces and much bigger brains, than any of our other animal relatives.  Maybe this sense of smell is an evolutionary hangover from earlier times when dogs were more human-like?
