Very interesting, scientists can identify race with earwax.
Mongoloid ear wax is dry, why Caucasoid and Negroid wet.
While Mongoloids are more likely to have the dry type of cerumen wax (gray and flaky), Negroids and Caucasoids are more likely to have the wet type (honey-brown to dark-brown and moist).
The Cerumen wax type has been used by anthropologists to track racial migratory patterns.

''Scientists believe that the mutation reached high frequencies in Northeast Eurasia and, following a population increase, expanded over the rest of the continent. Today distribution of the gene is highest in North China and Korea.
Wet earwax is believed to have uses in insect trapping, self-cleaning, and prevention of dryness in the external auditory canal of the ear. It also produces an odor and causes sweating, which may play a role as a pheromone. The usefulness of dry earwax, however, is not well understood. Researchers believe it may have originated to prevent less odor and sweating, a possible adaptation to the cold climate that the population is believed to have lived in.''
