How did people appear on Earth? When did the first person appear?

Each person at a certain period of his life thought about how people appeared on Earth. Centuries-old attempts to uncover this mystery have not yet led to a result, scientists to this day are arguing on this topic. It is logical that the truth must be sought in the oldest sources, which are closest to the moment of the origin of life.

Theory One: Humanity created by God

One of the first legends that sounded authentically was the stories that people created the Higher Reason, that is, God. Many peoples believed that the first people were made of clay. It is not known exactly why this material was considered "human". Most likely, this is due to the fact that clay is a radioactive substance, which is explained by the presence of uranium in the composition, and during the decay can release significant amounts of energy. Ancestors claimed that this was the energy that was used to create living beings. Legends of the first woman and man are known all over the world.

The second theory: people-hermaphrodites

According to other myths, telling how the first person appeared , people came from certain bisexual creatures - hermaphrodites. Adherents of this theory were the peoples of Africa and Sudan. They believed that the division of people by sex took place in a huge number of years.

The third theory: aliens

Modern versions of how people appeared in the world, connected this fact with the existence of extraterrestrial life. People believed that unearthly beings came to Earth and by artificial methods spawned life on the planet.

The fourth theory: a living cell

For a long time, many scientists rejoiced, believing that they had unraveled the mystery of how people appeared on Earth. It seemed quite obvious to them that the appearance of mankind is connected with the formation of a living cell.

They built various models, when a living cell emerged from non-living matter under the influence of chemical processes. It was alleged that this living particle was in the terrestrial ocean, which at that time was simply boiling with chemical reactions.

Later it was proved that everything necessary for the emergence of life was in space long before the formation of the Earth. Scientists insisted that the appearance of a living cell is a coincidence of circumstances and unforeseen biochemical processes that explain how 1 person appeared.

However, there were people who actively denied this version, because the content of the genetic code is an abstract record, which is impossible to predict. Francis Creek, who first discovered the genetic code, claimed that the living cell could not originate on its own. But even if we assume that this happened, there is no explanation for why such a variety of living forms arose that originated as a result of a single cell.

Adherents of this theory, as people came to light, cited the example of the development of Darwin, who believed that all living things were formed as a result of random and chaotic mutations. As a result of the natural selection of forms that were unfit and unfit for life, they perished. And those strongest who survived continued to survive and develop.

To date, such a theory, as people appeared on Earth, does not stand up to criticism. Despite numerous excavations, it was not possible to find any creatures from which another creature could have originated. If Darwin was right, now we could observe strange and amazing monsters.

The recent discovery of the fact that most of the genetic mutations has a clear direction, finally disqualified the theory of the "accidental case." And the rest of the mutations, which is caused by disturbances in the body, can not bear anything creative.

Theory Five: Evolution

The assumptions of this theory are that the ancient ancestors of man were higher primates, or monkeys. The modification had 4 stages:

• Australopithecus. They walked straight and could use some objects with their hands.
• Pithecanthropus. To other skills, possession of fire was added. However, the appearance was far from human, monkey features were traced quite clearly.
• Neanderthal. The structure of the skull was still different, but the general skeleton was close to the human skeleton.
• Modern man.

The drawback of this theory was that scientists could not explain in detail how mutations could contribute to the emergence of complex forms of life. Until now, no type of useful mutation has been discovered, all of which lead to the destruction of genes.

Theory Six: Hyperboreans and Lemurians

Esoteric history has its own interpretation of how people appeared on Earth. It is claimed that before the modern humanity the planet was inhabited by huge giants, which were called Lemurians and Hyperboreans. However, the theory was criticized, because, according to scientific facts, this simply could not be. Our planet does not have enough resources to feed such giants. And this is not the only refutation. If the growth of these creatures really reached enormous proportions, they would not be able to raise themselves, and with a sharp movement, the force of inertia would knock them down. In addition, their blood vessels would not withstand such a load, and the blood flow would break through their walls.

This is only a small part of the theories, but practical experience shows that each person chooses a version according to his worldview.

Numerous studies have shown that initially all the female embryos, and only during the period of hormonal rearrangements, some of them are transformed into a male gender. Many researchers believe that this is due to changes in the male genotype, which lead to violations in the Y chromosome. It is she who determines the male sex. According to these data, after some time the planet will be inhabited by female hermaphrodites. US specialists support this theory, as they managed to prove that the female chromosome is much older than the male chromosome.

With the help of modern research, a huge number of facts have been discovered, but even they do not give a clear explanation of how and where a person appeared. Therefore, people have no choice but to choose the most acceptable theory of the origin of life, trusting their intuition.
