How was the first man born on Earth? Is it really 6 million years of evolution?

Aristotle is recorded as probably the earliest explorer of the mystery of the origin of life. More than 300 years ago, he proposed that human life could occur naturally from inanimate matter, which is known as the autopoiesis theory of life, and until the 13th century people believed that sheep could grow from trees. In the middle of the 17th century, the Italian physician Reddy used experimental methods to discover that flies and other organisms were not naturally generated, but were born from a single egg of the parent, thus rejecting the autopoiesis theory and establishing the theory of biogenesis.

In 1864, the famous sterile infusion experiment and gooseneck flask experiment of the French chemist microbiologist Pasteur came out, which confirmed the view that microorganisms cannot arise naturally, and then completely refuted the theory of autopoiesis and established the theory of biogenesis.

But where did the first life on Earth come from? There are many explanations in the scientific community about the origin of life on Earth, such as life originating from lipid molecules, life originating from RNA, life originating from primordial oceans, life originating from Venus, life originating from deep-sea chimneys, life from earth's volcanoes, and life on Earth from outer space. The impact of a comet with water on the earth caused the origin of life, as well as the theory of terrestrial origin, the theory of natural occurrence, and so on.

Most of the above explanations make sense, because metamorphosis can arise naturally on land, in the ocean, in deep-sea chimneys, and in volcanic areas.

As for the birth of human beings, according to the research and exploration of scientists, the ancestors of modern humans actually originated in Africa, about 70,000 years ago human beings out of Africa began to spread to all parts of the world, and earlier such as the cave people, they had already been extinct 100,000 years ago, and were not the direct ancestors of human beings. The process of evolving from apes to modern humans is a long process, which may have taken more than a million years, this process is actually the process of continuous improvement and evolution of genes, this process is step by step, and it will not be achieved overnight, over time apes become more and more like modern humans, and finally completely grow into modern humans.

Therefore, it has been suggested that the birth of the first human being in this way is actually a false proposition, and that a wrong proposition naturally has no correct answer. What's more, the birth of human ancestors cannot be the birth of a person, but must also be the birth of a group. So far, there is no unified conclusion on the origin of human beings, and there are still many theories.

Modern scientists want to explore the mystery of the origin of human beings through archaeology, although it is theoretically possible, but the real situation is very difficult. Although the birth of human beings was millions of years ago according to modern science, millions of years are far from enough according to the evolution and evolution of an intelligent life. Dinosaurs have lived on the earth for hundreds of millions of years without evolving into intelligent life, perhaps the birth of human beings may be far more than millions of years, and the primitive life of human beings may have appeared hundreds of millions of years ago!

The first man on earth was the result of continuous evolution. It really evolved over more than 6 million years.

According to the research and exploration of scientists, the ancestors of modern humans actually originated in Africa, about 70,000 years ago human beings out of Africa began to spread to all parts of the world, the process of evolving from apes to modern humans is a long process, over time apes become more and more like modern humans, and finally completely grow into modern humans. Therefore, some people have proposed that the first human beings were born in this way, not to mention that the birth of human ancestors could not have given birth to a person, but must have given birth to a group.

I think it evolved over 6 million years, after all, today's science has proven that animals can evolve, and humans should also evolve, as some fossils of early humans can prove.

The world's first humans evolved through species. Humans evolved from a prehistoric shark that roamed the oceans more than 300 million years ago. According to the latest research, this primitive fish, called the genus Acanthus, is the common ancestor of all jawed vertebrates on Earth, including humans.

Re-analysis of a skull dating back 100 million years has revealed that it was an early member of modern jawed vertebrates, meaning that the jaw-mouth fauna includes trillions of living species of vertebrates, reptiles, mammals, and humans, from fish to birds.

The mystery of the birthplace of mankind.

Paleoanthropologists have been trying to find the right one for this series of questions. Most paleoanthropologists believe that human beings are marked by the manufacture of tools, and that human ancestors before the appearance of real people are called "pre-humans" by scientists.

Erection is a morphological sign of the separation of man from the main trunk of the common ancestor of the apes, and the area from which he separated from the main trunk can be described as the earliest cradle of humans. True people continue to evolve and develop, and Youzhao finally becomes a modern man, and at the same time forms different modern human races, and the area where this evolutionary process is completed is the last cradle of human evolution.

In order to explore the origin of human beings, we must first establish a premise, that is, human beings are a biological species, and they can only have one ancestor, and cannot be multiple ancestors. It cannot be said that blacks have one ancestor and whites have another.

This is how the first man on earth was born:

According to Darwin's theory of biological evolution, modern science says that human beings are the product of biological evolution, and modern humans and modern apes have a common ancestor, so we are the product of "biological evolution". From the perspective of the theory of human origin, human beings are the first to evolve from forest apes, and the first man on earth evolved from forest apes, and the origin process of human beings is also divided into three major stages, including the ancient ape stage.

The stage of man and ape, the stage of man who can make tools, and the later stage of ascension includes two major periods, ape and homo sapiens, which are divided into two stages: early and late.

Therefore, the origin of human beings is in the ancient ape, and human beings have maintained the process of evolution since the evolution of the ancient ape, which is mentioned in the British biologist Charles Darwin's "Origin of Species", and many evidences are cited to show that human beings evolved from the extinct ancient apes.

The saying that humans evolved from prehistoric sharks:

This theory is still significantly different from theories such as the evolution of plants and the creation of human beings. According to scientists, studies have shown that we have found some evolutionary characteristics in a primitive fish called "Acanthus".

That is, through an analysis of the skull dating back to 100 million years ago, it was found that it was an early member of the modern jawed vertebrates, which means that there is the same lineage between the animals that evolved separately, and the genus Acanthus existed in the earliest sharks and bony fishes began to slag before their respective evolutions, and this blood hall Liang Lao also continued into human life.

The first man on Earth evolved from Australopithecus.

The Chinese ape is considered to be the earliest ancestor of human beings, and since the beginning of the Chinese ape, the ancient apes have gone through a long evolutionary process. It was not until 3.8 million years ago that a branch of Australopithecus successfully evolved into the earliest ape-man, which was Australopithecus.

After about 1 million imitation and demolition years again, that is, about 2.5 million years ago, Australopithecus eliminated a large part of it under environmental changes, leaving only the stronger ones to survive, and it was these evolutions that became the later capable people. After that, Homo erectus evolved into Homo erectus and then Homo sapiens. Judging from the whole process, whether it is Australopithecus, ape-man or human, it does not appear in one individual, but in a large group.

The origin of life

The Earth was born about 4.6 billion years ago, and this data is not unfounded, but based on the decay rate of radioactive materials on Earth. The most representative of these is uranium, which costs an average of 17.5 billion per gram of uranium per year, which is converted into nitrogen and lead. Therefore, it is only necessary to determine the proportion of uranium and lead in the rock, and it is possible to roughly calculate the age and month of the rock's existence.

As early as the beginning of the birth of the earth, there was no life on the earth, and the surface of the earth was in a molten state. Over time, the surface of the earth gradually cooled, and after about 1 billion years, the first life on Earth finally gave birth to single-celled organisms. Of course, monocellular organisms do not appear in groups, but in groups.

By 3.5 billion years ago, the first bacteria on earth that could photosynthesize appeared, and it was cyanobacteria.

The first man on earth came into being through a natural evolutionary process.

Evolution in nature is a long-term cumulative process of change, and according to the results of scientific research, the ancestors of modern humans originated from the apes of Africa. Over a long period of time, the monkey underwent a series of mutations and adaptations, eventually developing into a modern human with intelligence and the ability to walk upright. So the emergence of the first man on earth was produced through the natural process of evolution.

The evolution of human beings can be traced back millions of years, and changes in the environment have played a crucial role in the evolution of human beings. When the Earth's climate became drier and forests decreased, our ancestors were forced to leave the trees and start moving on the ground. This transition played a crucial role in their later evolution, and they needed to learn to walk upright, use, and make tools.

As evolution progressed, humans gradually increased their intellectual and social abilities. They began to make and use simple tools, hunt and gather food and surplus filial piety. This behavior shows that our ancestors were capable of independent thinking and cooperation.

Over time, the human brain has gradually grown in size and the level of intelligence has also increased.

Human characteristics

1. Humans are thinking animals.

We have highly developed brains and the ability to understand, analyze, and create. This allows us to think, reason, and solve problems. Thinking is one of the biggest differences between humans and other animals, and it is also an important driving force for our progress and development.

2. Human beings have complex language and communication systems.

We are able to communicate through language and transmit thoughts, emotions, and knowledge. Language not only helps us communicate and cooperate with others, but it is also the foundation of our cultural and social development.

3. Human beings are social.

We are good at building social relationships and group cooperation. We are more dependent on each other than other animals and need to cooperate and help each other with others. Sociality allows us to live and work together, forming complex social structures.

4. Human beings have the gift of creativity and art.

We are able to create new things, invent new technologies, and express our emotions and ideas. Art plays an important role in our lives, not only to satisfy material needs, but also to pursue beauty and spiritual satisfaction.

5. Human beings also possess moral and ethical awareness.

We have the ability to judge the right and wrong of our actions, and have a sense of responsibility and obligation. Moral and ethical consciousness is the basis for our peaceful coexistence and compliance with rules and values, and it is also an important guarantee for maintaining social order and fairness and justice.

The theory of evolution states: "No living thing appears out of thin air, but has undergone a long evolutionary history."

So how did the first man on Earth come about?

It took about 1 billion years for the Earth to collide with various substances under certain conditions to give birth to the first life, primitive single-celled organisms.

Later, as single-celled organisms instinctively devoured each other and changes in the environment, multicellular organisms evolved, and gradually became diverse.

The evolution of species is a process from lower to higher levels, so the further back the organisms are, the higher they are. This is what evolution says about the origin of life.

More than 12 million years ago, forest apes were widely distributed in Africa, Asia and Europe, especially in the tropical jungles of Africa.

About 8 million years ago, our ancestors had to change from arboreal to terrestrial, and after more than 4 million years of evolution, the first apes to walk completely upright appeared-Australopithecus alfa!

Compared to crawling, walking upright is more labor-saving. And walking upright frees your hands, and they play a vital role in the rest of your evolution!

Over the next million years, a variety of upright walking apes appeared on the African continent, with Homo sapiens living in a much harsher environment than other apes.

Slowly, the able-bodied evolved into craftsmen who had long snouts similar to those of modern humans to moisten the air they inhaled.

Hair-sparse bodies help them dissipate heat better, and after millions of years they learn to use fire.

In the hundreds of thousands of years that followed, this is one of the reasons why there are now all kinds of people living in the world, with different habits and languages!

About 200,000 years ago, the Heidelberg people who returned to Africa were drastically reduced and even endangered by extreme drought. At this time, only resourceful and inventive people can survive, and although their numbers are reduced, their ability to adapt is greatly increased, and in the process they can only continue to live for their own future, so these people have imagination.

Mitochondrial DNA in human cells, inherited only in the maternal line, molecular biologists have found evidence from the mitochondrial DNA of humans, and people all over the world are descendants of an old grandmother in Africa, Lucy.

So far, an important node in the history of evolution has been confirmed.

The birth of any creature is not single, and the ancestors of human beings are the same, but this group of ancient apes made decisions and actions that other ancient apes did not make, and it was the current human beings that they achieved!
