Japanese scientists have recently discovered that a single unit of DNA determines whether an individual has either dry ear wax or wet. When I read this article, I was at a loss because I had naturally assumed that everyone had dry ear wax. Apparently, East Asians almost universally have dry ear wax while those of European and African descent have wet ear wax.
My question is: do you guys of European or African descent all have wet ear wax?
