3.8 billion years ago, primitive simple life was born in the earth’s oceans. As time goes by, simple life continues to evolve, with more and more types and more complex life. It was not until millions of years ago that mankind was finally born. It took about 3.8 billion years from simple life to the birth of mankind, which shows how difficult it is for life to evolve to the stage of intelligent life.
Although human beings have a general understanding of the evolutionary process of life, there are too many mysteries of life, and there are still many life mysteries that we have not solved. For example, how did life on the early earth come from? You must know that 3.8 billion years ago, the earth did not have any life, but some organic matter.
Since there is no life, early life should have evolved from organic matter, and how did organic matter evolve into primitive life? We must know that with the current scientific and technological strength of mankind, there is no way to create primitive life through organic matter. It can be seen that the evolution from organic matter to life is far more complicated and mysterious than we thought.
The core of life growth is evolutionary evolution, and evolutionary evolution follows the natural law of “natural selection by nature, survival of the fittest”. The ancient ancestor of mankind is the ancient ape. The ancient ape walked from the tree to the ground millions of years ago, and began to gradually evolve from walking on all fours to walking upright, which opened the way for the evolution of wisdom.
In the millions of years of human evolution, as the living environment and other ways continue to change, the appearance and bones of the human body are constantly changing over time. It took more than 2 million years to become what it is now.
The evolution of life is essentially a process of constantly adapting to the environment. When the environment changes, the direction of biological evolution will follow. Only in this way can organisms survive better, otherwise they will be eliminated by nature.
The constant changes in the environment make the direction of human evolution continue to change, and some things have also degenerated and disappeared on the road of evolution. Theoretically speaking, things that degenerate and disappear on the path of evolutionary evolution should not reappear. For example, the human tail degenerates and disappears during the evolution process, leaving only a little tailbone, which basically will not reappear.
However, according to the latest research of scientists, a bone in the human body that had been degraded and disappeared for a long time has magically reappeared. What is going on? This is a kneecap that has disappeared for a long time-the Fabry bone. It is estimated that many people have never heard of the Fabry bone, and this bone can be seen in many mammals.
Human ancestors also had Fabry bones, but in the later evolutionary years, the human body chose to degenerate it during natural selection, and it was gradually replaced by our current kneecaps. As for why there is such a replacement option, scientists have not yet given a definite answer. Since nature chooses to replace the Fabry bone with a new kneecap, it must be a mode of survival that is conducive to mankind.
From the perspective of biological evolution, since the Fabry bone has been degraded and disappeared for a long time, it should not reappear. However, since the beginning of the last century, scientists have discovered that Fabry bones have reappeared in a small number of people’s bodies. Research at that time found that people with Fabry bones accounted for 10% of the total population.
However, as time goes by, in 2018, a new survey and research found that this proportion has risen to 39%, which means that in a short period of time, the number of humans with Fabry bones has increased significantly, and it has reproduced the human world. The trend has been unstoppable. Perhaps in a few decades, the Fabry bone may fully reappear and regenerate.
Fabe bone degenerated and disappeared a long time ago, indicating that it is of no use to humans, but now it has reappeared. Many people think: This is human beings degenerating. Is this really the case? From the perspective of the theory of evolution, life will only become more and more complex through evolution, and there will be no degradation. This is also an answer given to us by the law of entropy increase.
The reappearance of the Fabry bone does not mean that humans are degenerating, so why does it reappear on the human body? So far, scientists have not found the root cause for this, but only put forward two speculations.
1. The weight of the human body continues to increase. I believe many people understand that as human beings enter the era of science and technology, with the help of science and technology, people’s living standards and quality are getting higher and higher. In ancient times, people often ate food and were hungry. At that time, there were very few people who were fat. Most people were very thin and had a relatively low weight.
However, after entering the technological age, the power of science and technology has made food production higher and higher, and various kinds of food continue to appear. People no longer have to worry about not having enough to eat, and as the quality of life continues to improve, people are getting heavier and heavier, and fat people continue to be born.
The increasing weight of the body will bring greater pressure to the knee joint. At this time, in order to reduce the pressure on the knee joint, the Fabry bone, which has been digested for a long time, “returns” and reappears in the human body.
2. The amount of exercise continues to increase. With the continuous improvement of living standards, people pay more and more attention to physical health, and the amount of exercise begins to increase. So the degenerated Fabry bone reappeared. For this answer, not many people have been recognized. In terms of exercise volume, modern people can’t compare with the ancients at all.
You must know that in ancient times, there was no advanced means of transportation. At that time, people basically relied on walking, even if it was thousands of kilometers away, many of them were on foot. In daily life, the ancients also needed a lot of labor to live, and the amount of exercise and activity far exceeded that of modern people.
The amount of exercise of ancient people far exceeds that of modern people, but why did people in ancient times not reproduce the Fabry bones? The reappearance of the Fabry bone was a matter of the last century, just when human technology began to enter its glory. This is obviously not a coincidence. The reappearance of the Fabry bone may have a close relationship with human technology, as long as we do not yet know what kind of relationship it is.
In any case, Fabry bone is a very beneficial bone for mammals, and it must have a certain effect on humans. It’s just that the ancients didn’t use this bone due to environmental factors, while modern people may need to use this bone due to environmental changes, so it reappeared.
The reappearance of the Fabry bone is a good thing for humans, not a manifestation of human degradation. The evolution of mankind has always been moving forward. For example, the capacity of the human brain has been reduced by about 10% compared to tens of thousands of years ago, but the intelligence of modern people far exceeds that of tens of thousands of years ago. A decrease in brain capacity does not mean that the brain is degraded, but rather a manifestation of progress.
This is the same as the CPU of a computer. With the continuous advancement of human technology, computer chips are getting smaller and smaller, but their functions are getting more and more powerful. The same is true for the human brain. In the future, the brain capacity may continue to decrease, but the complexity and precision of the brain will become more and more advanced. This is a manifestation of the evolution of the human body to a higher level of life. We should be happy about this.
