Where did life on Earth come from

The most authoritative scientific explanation now is that life on Earth originated in the primordial oceans. After tens of millions or even hundreds of millions of years, elements such as carbon and nitrogen precipitated together to form primitive lifeforms, and after a long period of time, primitive lifeforms evolved into the lowest cell bodies. Eventually, it evolved into marine life.

Eventually, it began to move to land.

Claim 1: Oxygen, nitrogen, carbon dioxide, methane, etc. in the primitive atmosphere and oceans are formed under the action of ultraviolet rays and lightning, and proteins and nucleic acids are formed, which slowly evolve and form cell structures and the origin of life.

Myth 2: Life is basically the first material brought by meteorites.

Claim 3: Extraterrestrial immigrants.

God made this nonsense, you are a monkey and have nothing to do with your parents.

The textbook says that oxygen, nitrogen, carbon dioxide, methane, etc. in the primitive atmosphere and oceans are formed by ultraviolet rays and lightning, forming proteins and nucleic acids, slowly evolving, forming cell structures, and the origin of life, but life can only be formed through the self-replication of material molecules, but how do they replicate themselves! This question also binds me! Could it be that molecules are smart?

This kind of talk is right.

To me the one I went upstairs withstairs.

He sub copied. It is made up of RNA (large nucleus) and DNA (small nucleus)...

It's not because they're particularly accompanied.

It started with organic matter.

Where did the "life" on Earth come from? The answer may surprise you!

The hypothesis about the origin of life that is now widely accepted by the scientific community is the "chemical origin theory".This hypothesis holds that life on Earth evolved step by step from non-living matter through extremely complex chemical processes over an extremely long period of time after the Earth's temperature gradually dropped. Here's how life is formed:

The first stage: the stage of generating organic small molecules from inorganic small molecules, that is, the chemical evolution process of the origin of life is carried out under primitive terrestrial conditions;

The second stage: the generation of biological macromolecules from small organic molecules. This process occurs in the primordial ocean, that is, amino acids, nucleotides and other organic small molecules, after long-term accumulation, interaction, under appropriate conditions (such as clay adsorption), through condensation or polymerization to form primitive protein molecules and nucleic acid molecules;

The third stage: the composition of a multimolecular system from biological macromolecular substances;

Stage 4: Evolution of organic multimolecular systems into primitive life. This stage was formed in the primordial ocean and is the most complex and decisive stage in the process of the origin of life.

The first life was a single-celled organism that lived in the earth's primitive oceans, and it was not until later that it evolved into multicellular, more complex structures and more complex life activities.

In ancient times, there was a lot of water on the earth, and the atmospheric content was mainly methane, ammonia, and hydrogen.

Water vapor, these gases produce chemical reactions when they encounter lightning, producing the most basic substances of life--- amino acids, and life is born, and later due to evolution, from aquatic to terrestrial, from low to high, until today.

Take the example of the evolution of life on Earth:

1. There is a belief that after an alien object hits the Earth, the organic molecules on the object are born to the Earth. The process of organic matter production on this celestial body is roughly the same as the following two mechanisms.

2. Oxygen, nitrogen, hydrogen, carbon and other elements on the earth form proteins under the action of the sun's ultraviolet rays and thunderstorms; It is also a coincidence that the earth is at the right distance from the sun, so there is life. Life then evolves further due to the constraints of the environment.

Then after n billion years of evolution, humans were born.

Three: Billions of years ago, Earth's weather contained much less oxygen than it does now, and the mushrooms produced during volcanic eruptions were about 200 degrees Celsius warmer than they are today. This condition is very conducive to the synthesis of organic polymers and amino acids from a variety of substances in the mushroom cloud.

These substances fall to the ground, and after years of interaction, they can synthesize RNA molecules that have the ability to replicate themselves, making the emergence of primitive cells possible.

How did life on Earth come about? Or related to lightning, Venus and Mars have missed their chances.

How did life on Earth come about?

Ask God, and maybe it will work out.

On the topic of where life on earth comes from, I personally believe that life is a form of active matter, a component of the matter of the universe, and all matter on earth is accumulated from the continuous release of dust particles (which can be collectively referred to as natural fixed matter) that has been continuously released by the burning of the sun. At the beginning of the earth, there was nothing on it, only an ocean, and land. Moreover, the atmosphere is weak and cannot withstand the impact of energy from the universe, the temperature of the land and ocean is very high, the oxygen is lacking, and the combined thunder and lightning invade the earth from time to time, and the environment is very harsh.

However, life is strong, and even under the influence of such harsh circumstances, it cannot be prevented from coming!

The special environment of the earth in the fixed position of the solar system will make the water form a stable liquid water phenomenon, and the formation of a stable liquid water body in nature will lead to the continuous birth and evolution of life phenomena, and the life on the earth comes from the ocean, and the ocean is the natural place and cradle of the evolution of life on the earth.

Why? Because, all life on the earth must rely on liquid water to survive, and the body of life also contains a large amount of liquid water, in order to control the random natural activities of life muscles, the animal body will contain 67% of the proportion of liquid water, the plant body will contain 50% of the proportion of liquid water, once the liquid water in the body of animals and plants is less than the above proportion range, it will soon die due to water loss.

It can be seen that stable liquid water is inextricably linked to life, and is the only natural factor that is indispensable. At present, in life science research, it has been concluded that all cellular life is based on single-celled microorganisms as the starting point of evolution.

The single-celled population of primitive life was derived from a stable liquid water (ocean) environment. Therefore, life on earth comes from the ocean, and the ocean is the place of evolution and the cradle of life on earth. I wonder if this is accurate?

Ocean. Because water is the cradle of life, the most primitive single-celled organisms on the earth were born in seawater, so life on the earth comes from the ocean.

Derived from the evolution of organic matter on earth, some organic matter has produced life in the accumulation of many years, and gradually developed into a variety of life.

It is very likely that after the occurrence of ** in the universe, a lot of life was formed and slowly survived on the earth, but it may also be due to other reasons.

Is Earth really a laboratory for extraterrestrial civilizations? How did life on Earth originate?

Where did the "life" on Earth come from? The answer may surprise you!

There are a lot of cells in the ocean, and even now, they will evolve and evolve, and in a few years they may be another world.

They all evolved from apes, and although this concept is well known, there are still many people who support mythology.

The most primitive life on Earth is made up of carbon and isolated organic matter. After a long period of evolution and evolution, a wide variety of species have been formed.
