Mites 20220624-

A recent scientific study confirms that Mites not only pass through the pores of the skin (especially on the face and eyelashes), but also they mate on the surface of our body. Certain species like “Demodex folliculorum” would be evolving towards increasingly simpler organisms and it is expected that in the future, following the course of their evolution, they could “merge” with people.

The findings are from research published in the journal Molecular Biology and Evolutionwhere the evolution of mites was analyzed “Demodex folliculorum”that they measure about 0.3 millimeters and are lodged on the surface of the skin since we are bornwith a growing trend in adult ages, as the skin pores.

The specimens studied could merge with humans, as a result of its reduced life inside the pores. In a process of gradual adaptation, inbreeding with humans is causing this species to get rid of genes and cells that it does not need.

Mites belong to the arachnid family and currently some 50,000 species are known, although it is estimated that there would be between 100,000 and 500,000 varieties that have not yet been differentiated

Symbiotic relationship?

In the event of the fusion of these hosts with human beings, the arachnids would leave their attributes of external parasite to create a symbiotic relationship with the people.

A relationship is defined as symbiotic when organisms of different species mutually benefit for their life development.

The first evidence of this mutation to symbiote, according to scientists, is that this type of mite has a greater number of cells at the beginning, unlike its adult stage. This is the reverse phenomenon of what occurs in parasites.

More curiosities of ‘Demodex folliculorum’

The report also warns about the possible disappearance of these mites. In case of not mating with other copies of different genes that can be passed on to the offspring, will find themselves at an “evolutionary impasse”which could precipitate its extinction.

The species examined corresponds to very simple organisms with microscopic legs that have three unicellular muscles and are able to survive on minimal doses of protein.

Demodex folliculorum is the species of mite that needs the least protein to live

It was found that during their evolution they lost the ability to produce melatonin, that is, the hormone necessary for them to be active at night, when they mate. However, they managed make up for this deficit with melatonin secreted by our skin while we sleep

On the other hand, the investigation found other curiosities of the Demodex folliculorum. Experts discovered that the penis in males has a peculiar disposition and that they also possess an anussomething that was previously denied.
