That's why I think the Discriminatory Smell write up is not what was intended. I'm human with a human brain and nose, yet I could easily identify people, pets, and quite a lot of other information that others could not. That should just be Acute Senses, not an exotic advantage.
Around 50% of the genes coding for sense of smell are broken or permanently turned off in humans. But trying to define what no human can smell but some other animals can is rather tricky.
Much easier to describe different EM wavelengths and discrimination of colors.
