Wet and Dry Ear Wax Map
I just found out that there is a stereotype that states Chinese have dry ear wax. Shockingly the stereotype has turned out to be true. Japanese scientists have mapped out wet versus dry ear wax and found out that in prehistoric China a genetic mutation occurred which makes ear wax dry. Dry ear wax is found in areas where prehistoric East Asians' descendants are found: namely East Asia, Southeast Asia, and North America. Despite some theories on sweat and smell there is no known reason why prehistoric East Asians evolved in order to have dry ear wax.
Catholicgauze, despite having R1a genetics, has very, very wet ear wax.
