According to a recent study, two varieties of moths share the territory of our face.
Rest assured, they are harmless! The idea of having microscopic beasties on the skin is not very pleasant either. Yet the University of North Carolina researchers from the United States, just revealed that two closely related species of spiders and ticks had taken up residence in the pores of our skin and in the follicles of our hair and our hair (including eyelashes). Their work, published in the journal, Science News, indicate that these mites having the names "Demodex folliculorum" and "Demodex brevis."
To make this discovery, scientists first analyzed the DNA of skin taken from the nose and cheek of several people. All adult study subjects and 70% of participants aged 18 years have proven DNA of Demodex mites carriers. If for Megan Thoemmes, who led the study, "everyone after puberty mites on their skin," the most interesting remains in the origin of these mites. The researchers continued their work and identified four different species of Demodex mites folliculorum on the skull of 70 volunteers from various geographical origins. People whose ancestors came from Asia and Europe had fewer different types of mites that people whose ancestors came from Latin America and Africa. By developing different types and skin colors from Homo Sapiens that man has created microscopic environment specific to areas of the planet and human migration. Demodex folliculorum propagating through physical contact within the same family, adult children and parents are carriers of similar moths.
These mites on the skin of humans for millions of years, are proving to be valuable data to track the movement of people in history.
