Human olfactory system can distinguish thousands of odors.
Second, the human olfactory system is enormously complex, underserved by industry and a potential gold mine.

By comparison the human olfactory epithelium covers about 5 10 cm2 and has about 10 40 million olfactory receptor cells.
We hypothesize that true human olfactory abilities are obscured by cortical inhibition.
We applied the scheme to the human olfactory receptor (OR) genes.
Tastebuds offer a limited means of detection, however, compared with the human olfactory system, which can perceive thousands of different chemical aromas.
(A biologist at Caltech subsequently disputed the finding, arguing that it contained mathematical errors, though he acknowledged the "richness of human olfactory experience").
