The DNA demonstrates how mites are forming an evolutionary partnership with humans ...

Mites were discovered on your skin by you. These tiny creatures even use your skin for reproduction.

According to a press release by the University of Reading, one species ofmite is moving from parasite to partner in an evolutionary relationship with humans.

From external parasites to internal symbionts

"The first ever genome sequencing study of theD. folliculorummite revealed that their isolated existence and subsequent inbreeding are causing them to lose unnecessary genes and cells, and move towards a transition from external parasites to internal symbionts," said the author.

These organisms are slowly but surely merging into a symbiotic system with us.

These mites have a different body part genes than other similar species because of their adaptability to a sheltered life inside pores. These changes to their DNA have resulted in some unusual body features and behaviors," said Dr. Alejandra Perotti, a co-led the research.

What do we know more about these mildes?

They are extremely simple organisms with tiny legs powered by just three single cell muscles and survive with the lowest number of proteins seen in this one.

As they lack UV protection, they are unable to produce melatonin. However, they are able to extend all-night mating sessions with the melatonin secreted at the dawn.

The males have a penis that protrudes upwards from the front of their body, meaning they have to scout themselves underneath the female when mating and both have to cling onto human hair.

They have many more cells at a young age, especially at their adult stage, and may be on the path to extinction due to lack of exposure to potential collaborators, who may add new genes to their offspring.

Wrongfully accused

Several previous studies had speculated that the mites do not have an anus and therefore must accumulate all their feces throughout their lifetimes before releasing it when they die, causing skin inflammation. The new research has found that they do have anuses, thus they are not to be blamed for skin irritations.

Mites have been linked to a slew of things. A close connection with humans might suggest that they may have beneficial roles, for example, in maintaining the pores in our eyes unplugged, according to Dr. Henk Braig, the co-author of Bangor University and the National University of San Juan.
