6 curious defects of the human body

Much is made of claims that the human body is perfectly designed, that our species can handle anything, or that adapts to all physical and mental demands, to changing times and to the changing rhythms of life that society does not have subjected.

In fact, it is partly true that we have proven to be a very resilient animal species, capable of spreading across the entire planet and living in the harshest situations. However, there are also defects of the human body.

Our physical condition presents elements of weakness that surely we are all unaware of (sweating, intense body odors) and that we take as something "natural". Furthermore, we are at a time when medicines, fabrics and furniture that do not harm our body are constantly being developed.

defects of the human body

Some expert biologists and researchers in evolutionary biology expressly show us that the human body has more failures than one would imagine. Some reactions of the human body highlight these deficiencies, mechanisms that are activated precisely to regulate physical or mental alterations.

In this article we will review some of these most outstanding imperfections of the human body and we will explain what they consist of.

1. Sweat a lot

To make a good explanation, we will compare ourselves with our sister species, the mammalian animals, since they also have the sweat glands to regulate their body temperature, but they have fewer of them which makes them less vulnerable depending on what situations.

The human body, on the other hand, sweats excessively and that It makes him dehydrate very easily., without the explicit need to do a lot of sport. An example is when we sweat because of nerves or anxiety. The brain emits exaggerated signals of tension that causes the glands to fire.

2. The eyelids

Here we find another of the great defects of the human body and its design, especially in a crucial member for our existence. It's all about the eyelids. That fleshy part that covers the eyes to protect them from dryness, microbes and other elements that are harmful to the eyes, is partly responsible for various vision problems.

It turns out that our eyelids are as fragile as the skin of an apple. Being so thin, they do not adequately or effectively protect our eyes, as is the case with other living beings such as the hippopotamus or the crocodile.

3. the appendix

The appendix is ​​a part of the large intestine that is located at the junction of the small intestine. Although in some animal species it does have a function, such as marsupials like the koala, in humans this part of the digestive system is only good for one thing: getting infected. This has made the presence of this failure of the human body cost many people their lives.

4. On the skin...

The skin is another of the great defects of the human body, if not the one that is most harmed. According to pharmaceutical studies, 75 percent of the pathologies of the human body, are suffered in the skin. Psoriasis, irritations, burns, cuts or acne are usually caused by the delicacy of the thin layer that protects our interior.

A derivative of these problems is the little fat it contains, as well as the fine texture that it is composed of. If we do not resort to sun creams in summer, moisturizing creams in winter, and pills against some infections, the human body would be unable to solve them. This is perhaps a consequence of the use of clothing over hundreds of thousands of years.

5. Autoimmune diseases

All autoimmune diseases typical of our species are in some way a failure of the human body, since they exist by genetic imperfections related to the functioning of cells who should be in charge of our protection.

6. the mode of delivery

In our species there are many deaths from childbirth, and until a few decades ago these were even more frequent. This is the result of bipedalism, since when we adapt to walk on our legs, the woman's pelvis narrowed, causing the tube through which babies must pass to narrow.

The human body and technology

Quite the opposite of what has happened, is happening and will happen within the animal kingdom, the human body and our physical condition do not seek perfection, evolution, more so adaptation. Reptiles, apes, birds or cats have been developing a biology that surpassed its predecessor, a fact that has made them born survivors.

On the other hand, the human does not have as much need to evolve biologically to survive, but survives through the manipulation of the environment and the creation of technology. It adapts with accessories such as clothing, the natural materials that surround us and the social activity that humanity develops. But for physical purposes, we can do little.

Technology will take care of the rest. She will be the one to make up for the deficiencies of the human body, perfecting it through nanotechnology and robotics, as well as replacing human organs with artificial ones. Vision microchips or bionic prostheses (arms, hands) are already a reality.
