The issue of human origin has always been the most concerned and headache for humans. There are many theories about the origin of humans, including evolution theory, alien theory and genetic modification theory.

At present, the mainstream scientific community’s explanation of the origin of human beings is based on the theory of human evolution , but evolution theory only explains some problems of the origin of human beings, not all problems.

Mysteries in the evolution of human beings

In the evolution of human beings, there are too many special events that cannot be described by luck. Why can all human chromosomes finally be traced back to a man 60,000 years ago? Why can human mitochondrial finally be traced back to a woman 140,000 years ago?

And tens of thousands of years ago, human gene mutations seemed to suddenly become our ancestors, Homo sapiens , and then eliminate other races in a very short time, and eventually develop a splendid civilization.

or humans are really the sons of the universe. At every key point, they can evolve in the right direction. In the end, it took less than 6 million years to complete the evolution from Australopithecus to today's humans. The dinosaurs that once existed on Earth for hundreds of millions of years could not escape the fate of destruction.

So, generally speaking, humans are gradually evolving, but in the process of evolution, whether external forces are involved in the intervention needs more research.

However, in recent years, humans have frequently experienced rebirth of . In the history of human evolution, the disappeared tail is now in the news. The long-degenerated Fabei bone has also been frequently discovered among modern young people. According to relevant research institutions, this proportion has reached 39%, and is slowly expanding.

So are human beings evolving or degenerating now?

If it is evolution, why do organs abandoned during the evolution process reappear?

First of all, we need to understand a concept, that is, there is no evolution or degeneration on biology , and there is only the saying "evolution".

The creatures on Earth, whether animals or plants, evolve according to different environments. For example, 300 million years ago, the oxygen concentration on the earth was about twice that of today.

At that time, both animals and plants evolved in the oxygen-rich environment. Some organisms that were not suitable for the oxygen-rich environment were eliminated and destroyed. In order to adapt to the oxygen-rich environment, some organisms evolved into huge sizes. The size of a dragonfly can reach about 1 meter.

so the Fabei bone that once disappeared has now reappeared in the human body. An important reason is that the environment changes, which has led to the increasing quality of life of human beings.

What followed was the increase in human weight. In order to withstand increasing pressure on the knees, the Fabei bones tended to increase significantly. In other words, the emergence of Fabei bones is just a normal evolutionary process.

Where is the ultimate direction of human evolution?

From a narrow perspective of humans, any other same species is similar, but in each species, individual individuals are actually different. Just like two people, it is impossible to have exactly the same genes.

is also these slight differences that allow the same species to have different results in the evolution process. Therefore, 6 million years ago, humans and chimpanzees had common ancestors. In order to survive in the harsh environment of the earth at that time, human ancestors chose to evolve their brains, while chimpanzees' ancestors evolved their powerful limbs and eventually evolved two different species.

In the past 6 million years, the evolutionary process of human beings is actually a process of gradually increasing brain capacity. The larger the brain capacity, the more neural network can be added, and it also means that it is becoming smarter.

Judging from the current social situation, humans use their brains more than ever before. In other words, if humans continue to evolve, they must also evolve their brains.

However, the proportion of the brain and the body is extremely inconsistent with the energy consumed by the human body. One weight only accounts for 2% of the human body's weight organs, but it consumes about 20%-25% of the total energy of the human body.

According to the law of conservation of energy, energy is generated out of thin air and will not disappear out of thin air, but it is just converted from one form to another.

Then, if the human body absorbs limited energy, if the brain continues to evolve, it will inevitably lead to a decrease in energy consumed by other parts of the human body, and after the energy decreases, it will inevitably degenerate.

Is this the reason why the programmer who uses his brain overuses abandons his energy-consuming but useless hair and becomes Mediterranean ?

So in the future, after the evolution of the human brain, the head will become bigger and bigger, the hair will disappear, and the hands and feet will gradually shrink, smaller and shorter. Is this image very familiar?

last interesting question.

If society is differentiated, part of it uses more brains and eventually evolves the brain; while the other part, athletes need strong bodies and strong limbs.

So will the future evolution of human beings evolve in two directions? Is the result like humans and chimpanzees 6 million years ago, eventually becoming two different species?
