I have read that Indians have O-type blood and moist earwax, which is seen Caucasians and Negroes. I have read some Indians have the same rate of Rh-negative blood as Basques, Celts, Guanche, and Berbers. Among them, Mayans, Incas, and Mapuches.
Moist earwax? Did not realize it came any other way? You mean some people have dry earwax?
I guess that would explain some puzzling things, like ear candles.
My mom's ancestry is part Ojibwe. Now I'll have to ask my siblings and kids whether they have dry earwax or moist earwax.
Looked it up -- 95% of East Asians have dry, 97% of Europeans and Africans have moist. Native Americans mostly have dry.
