Stories that start with a sniff


Is it true that dogs have a better sense of smell than humans? In a word, yes. Their noses contain about 10 times more olfactory neurons that ours do. But that doesn’t mean that they are better at every type of smelling. Because of their anatomical prowess, dogs excel at long-distance detection. But humans are no slouches with a bigger brain that can process complex aromatic information. Turns out that we are better at sniffing up close, which may explain the underpinnings of our shared evolutionary with dogs: They sniff out and possibly catch the prey, and we cook it up.
