The other is alkaptonuria, or black urine disease, also plenty frightening. As for our different ear odors, they came about because of a tiny change, just one little letter in the genetic alphabet.. . Also mentioned in the study: Africans have wet, yellowish-brown wax, and Native Americans — similar to East Asian folks —.. There are well-known racial differences in ear wax. Dry wax, which is grey and flaky, is commoner in Asians. Wet wax predominates in Africans and Caucasians, and is brown and sticky Earwax contains ethnicity-specific data, according to a new study. Written by David McNamee on February 13, 2014. Earwax is a neglected body secretion, according to researchers at Monell. (The other type of human sweat glands, the eccrine glands, exude mostly water and salt; everyone's got lots of those.)

The color of the candle wax matches the light brown-colored wax of the human ear, making the distinction between the two waxes more difficult for a layperson.

He goes into details about the codons and base triplets that result in interesting but peripheral racial differences in hair texture, ear wax consistency, and type of sweat glands, but completely ignores the genetics of intelligence There are well-known racial differences in ear wax. Dry wax, which is grey and flaky, is commoner in Asians. Wet wax predominates in Africans and Caucasians, and is brown and sticky.

The Differences Are Real. IN 1969, in the appropriately academic context of The Harvard Educational Review I questioned the then and still prevailing doctrine of racial genetic equality in intelligence. I proposed that the average difference in IQ scores between black and white people may be attributable as much to heredity as environment Ear infections happen when one or both of the eustachian tubes is swollen or blocked, causing fluid to build up in the middle ear. When that fluid becomes infected, you have an ear infection.
