Chinese scientists have confirmed that human beings evolved from fish, what has been the evolution o

It is understood that this year is the 2.5 million year of the birth of our human beings, and human beings also evolved from a fish in 2.4 million years, which has countless doubts in almost everyone's minds. However, in 2017, Chinese scientists published ** to confirm that human beings are not a fish, but a primate, and also a mammal of great scientific significance.

1. The evolutionary process of mankind

As for the evolution of human beings, in fact, many people think that it is a stage of tens of millions of years. In fact, this is also true of the evolutionary experience of human beings. The main reason why humans have evolved to be what they are today is because their biological characteristics are different from those of other animals, which is why it has evolved over tens of millions of years.

Scientists have counted a total of 4.4 billion years, and judging from the fossils found so far, scientists believe that the time of human evolution is actually longer than these 4.4 billion years. If we just look at the time, we can't know exactly how many seconds that number will be. But in fact, scientists have found that there is no accurate answer to this time, it is just a hypothesis.

2. The role of evolution

The main purpose of human evolution is to better adapt to the development of the world. Because evolution has enabled humans to learn how to use resources, how to adapt to their environment, and how to develop from an early age. Therefore, this method allows human beings to better adapt to the development of the world, and at the same time find a direction for human development.

In the process, humans will encounter various obstacles that lead to no way to survive. At this time, evolution can make human beings better in these aspects. Because evolution has allowed humans to adapt better to the world.

At the same time, let this adaptation better and make humanity more mature. <>

3. Challenges facing humanity

At present, more and more people in the world have left the earth due to environmental problems, and more and more people are dying because of the problems of the living environment, and the environmental pollution problem caused by the increasing number of human beings living on the earth is also worsening. The earth itself is constantly devouring the natural resources we depend on. According to statistics, the concentration of carbon dioxide in the ocean reaches 1 billion tons every year; The temperature of the earth itself is constantly rising; Global warming is accelerating the extinction of species on Earth.

The evolution of human beings has actually gone through a lot of human beings, initially due to evolution, and then evolved into early ape-man, then late ape-man, and then evolved into modern man.

This also verifies that in the process of evolution, apes walked upright before brain development. In addition to the ape-to-human process, paleontologists have found many more examples of intermediate evolution, dating back hundreds of millions of years.

We humans evolved from a branch of Australopithecus 30 million years ago, and went through a total of four stages.

Humans did evolve from fish, not just humans, but all terrestrial vertebrates were ancestors of fishAbout 300 million years ago, a group of flesh-finned fish landed on land, slowly adapted to the terrestrial environment, and evolved into amphibians, then reptiles, then mammals, and humans were born in this evolutionary process.

Modern biology believes that the evolution of living things is a process from simple to complex, not only the ancestors of humans are fish, but all living things on the earth today should be traced back to a common ancestor, and this original ancestor is called Luca.

It was the last common ancestor of all species before they diverged, and Luca was probably not the first life on Earth, but the first to reproduce and survive, and its offspring continued to evolve, eventually giving birth to the entire Earth's ecosystem.

Scientific research confirms that humans evolved from fish

Ancient fishes that lived hundreds of millions of years ago swam in the ancient ocean flexibly, which is the scene recovered by Chinese researchers based on a batch of fish fossil specimens found in the Chongqing peculiar buried fossil reservoir and the Guizhou Shiqian fossil reservoir.

Among the newly discovered fossil specimens, researchers have found the world's oldest jawed tooth fossils, and discovered a number of ancient fish fossils such as the oldest jawed miracle mountain fish, revealing the rise of jawed vertebrates.

At the same time, it can effectively understand the development process of human beings, which can make us cherish life more, and at the same time, it will allow us to create a better future, and the study of human origins is not important, but most importantly, the research itself is very important for human beings.

"From Fish to Man" has key evidence, and it's a very good thing to see such news in itself, because we will be rewriting our ancestors or history. However, in the face of such a problem, there are also two voices on the Internet. The first voice is those who agree with continuing to study this issue, saying that this is the right thing to do, to satisfy people's curiosity, and to allow more people to understand how their ancestors evolved.

However, the second voice is not very friendly, thinking that there is no real point in research, and that there is a lot of money flowing into it every year, and they don't even know what the purpose of studying the origin of human beings is, but they just think that it is a waste of money.

In fact, from my personal point of view, sometimes we can't just analyze anything from the surface, we have to go from the surface and then go deeper. For example, if on the surface, it seems that there is no need for human beings to study what the origin of human beings is, after all, it has been so long, so why bother to go deeper. Because in this case, it seems that it is a matter of labor and money, which has no meaning for human life and development.

In fact, from my personal point of view, I think it is very necessary to study the origin of human beings. Understanding the origin of human beings, whether for real evidence or other reasons, not only allows us to understand how humans came to be, but also helps in medicine and in industrial and agricultural production.

The study of human origins allows us to better understand ourselves, to have a clearer understanding of the theory of evolution, and to study the direction in which we are evolving.

It provides a theoretical basis for the subsequent study of human evolutionary history, and can help scientific research and exploration in the field of biological origin and establish a database.

It can better restore the history, let us have a certain understanding, let us understand better, and use the technology from it to analyze and dissect, so that there will be greater breakthroughs in technology in the future.

At first, humans did evolve from apes, but later due to the flood, many humans went to the water to survive, and slowly turned into fish, and then into humans.

It first evolved into jawed animals, and then evolved into humans over thousands of years.

The evolutionary process is that it is possible that humans first lived in water, began to grow legs in order to better hunt and eat, and then began to live on land, and eventually evolved into humans.

In the beginning, people were fish, because of the environment, fish could not live in the sea, and then on land, they slowly developed limbs, and some of the fish remained on land.

There is no theoretical basis for this speculation, and Darwin's theory of evolution is now widely adopted. There is no direct connection between humans and fish.

Researchers at the Chinese Academy of Sciences have discovered a fish that lived 100 million years ago, which has an upper jaw and a lower jaw, and is called a jawed fish. Scientists have found that this fish is the ancestor of most vertebrates, such as humans. Exactly how it evolved is unknown, as there was a long gap in the intervening period.

However, 100 million years ago, the body length of jawed fish was only three centimeters, and then it has evolved into so many species, which shows that it is very able to adapt to changes in the environment and has a good ability to evolve.

If you're particularly interested in human evolution, look at the literature that has all sorts of theories about who our ancestors were. It has always been believed that the ancestors of humans were ape-man, but ape-man also evolved from other animals, and this animal may be a jawed fish. This fish has pairs of nostrils and teeth, as well as many organs.

These organs may be the advantage of later evolution, which can compete with other species and eventually become the overlord of the earth. But the evolution of living things takes a very long time, let's say tens of thousands of years, hundreds of millions of years.

Some netizens are worried about whether the fish they eat now is their former ancestor, and this statement is not valid. The current discovery is that the fish is the common ancestor of fish and humans, but it was more than 400 million years ago, and it has little connection with the current fish. So people can eat fish to their heart's content without worrying about some problems.

Nowadays fish are far, far away relatives, and it is unknown how far away. Because the animal has a strong ability to evolve and has natural advantages in body structure, it has good development potential and the ability to cope with the environment, and can become a very good company. Before that, the jawed fish evolved into the Tyrannosaurus rex and became the apex predator.

First it evolved from fish, then gradually evolved into amphibians, began to grow legs, then evolved some organs, and finally developed into the appearance of humans.

It is an evolutionary process from fish to man, and it has gradually undergone a long part of the changes in the process of evolution.

At present, it is only the study that it evolved from fish, and the specific evolutionary process has not yet been announced, and we look forward to the final research results.
