Whether primitive life was born in a primordial atmosphere or a primordial ocean

According to the available data, it is more likely that primitive life arose in the ocean. Because the birth of life requires the protection of the ocean, at the beginning of life, the earth was in an extreme environment. The air is filled with methane and other gases, and the sun's radiation is so intense that life can only avoid these deadly radiations in the depths of the ocean.

In addition, the depths of the ocean can provide not only a safe environment, but also the materials, energy, solvents, temperature (mainly submarine craters), and other conditions necessary for the initial biochemical reactions to occur, and many evidences have been found from geological evidence that life was born in the ocean.

Pristine Ocean. You can think about it, since there is no oxygen in the original earth, and there is no ozone, a large amount of ultraviolet rays contained in sunlight will be driven to the earth's surface for a long time, and the air will be subjected to strong ultraviolet action, which will cause the original organic matter to be destroyed, and even if there is life, it will be exposed to strong ultraviolet rays and die.

However, because water can absorb ultraviolet light, in the deeper depths of the primeval ocean, there is almost no action of ultraviolet light, and the resulting organic matter and life are preserved and genetic mutations occur under the action of very small amounts of ultraviolet light, forming evolution.

Personal opinion.

100% pristine ocean.

Paramecium is the first creature on Earth!

And it's living in the ocean.

Right. The first in the world to appear is a vacant primitive eukaryotic cell, which is large in size and already has a primitive nucleus.

Current fossil material suggests that the earliest eukaryotes appeared about 1,81.4 billion years ago. These fossils are found in sedimentary rocks.

It shows that eukaryotes also evolved in the ocean.

From 3.4 billion years ago to 181.4 billion years ago, it was a period of evolution of prokaryotes. It has been a long time, about 2 billion years, but the rate of evolution has been slow. After the advent of eukaryotes, a true sex appeared, and the rate of evolution was greatly accelerated

About 1 billion years ago, multicellular animals began to appear; It was the Cambrian period hundreds of millions of years ago.

The oceans are already overgrown with many species of seaweed, and various invertebrates with skeletons.

also appeared; Later, vertebrates appeared; At the end of the Precambrian period, the upper layer of the atmosphere gradually appeared and formed a quivering ozone layer, creating the conditions for living on land. The successful landing of organisms occurred roughly after the Cambrian period.

The origin of primitive life is a scientific puzzle that has not yet been fully answered. However, there is a theory that primitive life originated in the primordial ocean. The following is an analysis of this doctrine.

1. The origin of primitive life

The origin of primitive life is a scientific puzzle that deals with the nature of life and the origin of the Pina Cave. At present, there are many theories in the scientific community about the origin of primitive life, including the geochemical theory, the theory that life originated from meteorites, and the RNA world theory. These theories have their theoretical basis and experimental support, but there are still certain controversies and uncertainties.

2. The doctrine that primitive life originated from the primordial ocean

The theory that primitive life originated from primordial oceans is a relatively broad theory, which holds that the earliest forms of life were born in primordial oceans. The main bases for this doctrine are:

1.The pristine ocean was one of the first suitable environments for life on Earth, with suitable conditions such as temperature, moisture, oxygen and nutrients.

2.There are large quantities of organic and inorganic matter in the primordial oceans, which can provide the necessary material basis for the origin of life.

3.There are a large number of electrons and energies in the primordial oceans that can provide the necessary energy base for the origin of life.

4.There are large quantities of hydrothermal fluids and hot springs in the primeval oceans that can provide the necessary conditions for chemical reactions for the origin of life.

3. The controversy that primitive life originated in the primordial ocean

Although the theory that primitive life originated in the primordial ocean has its theoretical basis and experimental support, it still has some controversy and uncertainty. Some of the main controversies and uncertainties include:

1.Whether the environmental conditions in the pristine ocean were sufficiently suitable for the origin and evolution of life.

2.Whether the organic and inorganic substances in the primordial oceans are rich and diverse enough to provide the necessary material basis for the origin of life.

3.Whether the electrons and energy in the primordial oceans were strong and stable enough to provide the necessary energy base for the origin of life.

4.Whether the hydrothermal fluids and hot springs in the primordial oceans are stable and durable enough to provide the necessary chemical reaction conditions for the origin of life.

You misunderstood.

To put it simply, the primordial earth and the primordial ocean are not in the same time period, and the primordial ocean appeared at least a few hundred million years later than the primordial earth. It was the primordial earth that appeared first, and it took hundreds of millions of years before the primordial oceans began to appear. Because the temperature of the primitive earth was too high for life to survive, it was only after hundreds of millions of years that the earth cooled down and there began to be oceans, and life was born.

This line of earth is no longer a formed life, and can be replaced by primitive or something, so the earth originated 450 million years 1000

In the most primitive earth, there was no ocean, and at that time the earth was a blazing fireball, and nature could not produce life. The primordial oceans were created only after the earth was slowly cooling.

Primitive life originated from human beings, yes, I think so.
