Why is there hair on your ass?

Strange question is not it? But it makes sense, what is the advantage of this hair growing in this particular place, you see?

Although the evolution of our knowledge, we humans can now have a very sophisticated computer and be able to send robots on Mars and transform everything on the surface to meet our needs, we still do not know precisely why does he have hair on the backs of any of us, and I think it is not surprising to know that only a few researchers have been responsible for conducting research on this subject.

But enough studies have been devoted to the medical field of the subject, in particular the health problems that can be caused by the hair on the back, such as: "hair follicle", a skin lesion that can be repeated more than once in the same person and caused by the penetration of hair in the skin Just above the confluence of the buttocks.

If someone has a back, he may know that the donkey's hair has more disadvantages than positives, so what is the purpose of his existence - if any?

Well, some hypotheses talk about this subject, here are some of them:

The first hypothesis:
It is the absence of a good evolutionary reason for its disappearance!

The reason for the presence of hair in the back is that there is no good reason for development to explain its mere disappearance, which is of course sometimes unsatisfactory and, at this stage of the history of human culture it can also be considered an ugly cause. At one point, a factor preventing two humans from having a child.

But it is very important to know that all our physiological factors are not the result of the reason for evolution.

The second hypothesis:
They "communicate through the smell", just like other animals!

Body odors have a bad reputation in our time, but olfactory communication has undoubtedly played a very important role in the evolution of man, which usually explains the presence of hair in places that emit odors .

The hair in these areas keeps the oily or oily secretions that have their own smell, as well as the types of bacteria that feed them, which adds other smells.

Since we produce many aromatic compounds, each of us has our own natural sanctuary. Each of us has his own perfume. Although our first human ancestors were like other animals - they probably were - their own perfume could have helped them From identifying control areas to getting a partner, feeling at home. background was one of the factors that helped our early ancestors to reinforce their distinctive smells.

The third hypothesis:
These are "frictions", in addition to the release of smells!

Walking and jogging have long characterized humans. Skin contact (especially in damp, soiled areas) may cause skin irritation and rashes, the most serious being burnout.

It is even possible that one of the functions of the hair is to keep in place the fatty secretions or wax - which help to release the smell of the body - and that these secretions can therefore act in a way as a natural moisturizer.

In fact, the last hypothesis seems more realistic than before, but the problem is that the tests are very difficult because it is very difficult to try to remove the hair and travel 40 kilometers.

There is also no way of knowing whether the irritation that may result is due to lack of hair or the method used to depilate them. To determine if the hypothesis is true or not, we can simply do it: interview several hundred professional runners and ask questions about the scope. The importance of removing the donkey's hair for them, and knowing the speed of this process in addition to the impact on their athletic performance.
