Much is made of the assertions that the human body is perfectly designed, that our species can withstand anything, or that it can adapt to all physical and psychic demands, to changing times and to the varying rhythms of life that society does not subject it to.
In fact, it is partly true that we have proved to be a very resilient animal species, capable of spreading across the planet and living in the toughest situations. However, there are also defects in the human body.
Our physical condition presents elements of weakness that we probably all don’t know about (sweating, intense body odors) and that we take as “natural”. Moreover, we are in a moment where we are constantly developing medicines, fabrics and furniture that do not harm our bodies.
The defects of the human body
Some expert biologists and researchers in evolutionary biology expressly show us that the human body has more flaws than we could ever imagine. Some reactions of the human body highlight these deficiencies, mechanisms that are activated precisely to regulate physical or psychic alterations.
In this article, we will review some of these major imperfections of the human body and explain what they are.
1. Sweat a lot
To make a good explanation, we will compare ourselves with our sister species, the mammal animals, since they also possess the sweat glands to regulate their body temperature, but they have less quantity that makes them less vulnerable in what situations.
The human body, on the other hand, sweats excessively and that makes it dehydrate extremely easily , without the explicit need to do much sport. An example is when we sweat because of nerves or anxiety. The brain emits exaggerated signals of tension that make the glands shoot up.
2. The eyelids
Here we find another of the great defects of the human body and its design, especially in a member that is crucial to our existence. It is the eyelids . That fleshy part that covers the eyes to protect them from dryness, microbes and other harmful elements in sight, is partly responsible for several vision problems.
It turns out our eyelids are as fragile as the skin on an apple. Because they are so thin, they do not adequately or effectively protect our eyes, as is the case with other living creatures 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 large and small intestines. Although in some animal species it does have a function, such as marsupials like the koala, in humans this part of the digestive system serves only one purpose: to infect. This has meant that the presence of this failure of the human body has cost many people their lives .
4. In the skin…
The skin is another of the great defects of the human body, if not the most damaged one. 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 that it contains, as well as the fine texture that composes it. If we don’t 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 the autoimmune diseases that are characteristic of our species are in some way a failure of the human body, since they exist because of genetic imperfections related to the functioning of the cells that should take care of our protection.
6. The mode of delivery
In our species there are many deaths in childbirth, and until a few decades ago these were even more frequent. This is the result of bipedalism, since when we adapted to walk on our legs, the woman’s pelvis narrowed , making the duct through which babies must pass to become narrower.
The human body and technology
The opposite of what has happened, happens and will happen within the animal kingdom, the human body and our physical condition does not seek perfection, evolution, but adaptation. Reptiles, apes, birds or cats have developed a biology that surpassed their predecessors, a fact that has made them born survivors.
On the other hand, the human being does not need so much 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, there is little we can do.
Technology will take care of the rest. It will be the one to make up for the shortcomings 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.
