Please tell me what is the origin of life? 5

The collapse of the Great Dao or the evolution.

The origin of life is of biochemical origin.

The process is the evolution of life on the earth from non-living substances through extremely complex chemical processes over an extremely long period of time after the temperature of the earth gradually drops.

Creatures can spawn at any time from non-living things, or from some very different object. For example, in ancient China, the so-called "meat rots out worms, and fish withers beetles".

In the Middle Ages, it was believed that leaves that fell into the water turned into fish, and when they fell to the ground, they turned into birds. Spontaneous generation is a widely popular theory before the 19th century, which holds that life occurs naturally from inanimate matter. For example, in ancient China, it was believed that "rotten grass turned into fireflies" (that is, fireflies were produced from rotten grass piles), carrion maggots, etc.

Stage:

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, was carried out under primitive terrestrial conditions. It is important to note Miller's simulations. In this experiment, a flask containing an aqueous solution represents the primordial ocean, and its upper spherical space contains a "reducing atmosphere" of hydrogen, ammonia, methane, and water vapor.

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

In the third stage, a multimolecular system is formed from biological macromolecules. How did this process come about? The former Soviet scholar Obalin proposed the agglomeration hypothesis, and he experimentally showed that when proteins, peptides, nucleic acids and polysaccharides are placed in a suitable solution, they can automatically concentrate and aggregate into dispersed spherical droplets, which are aggregates.

Obarin et al. believe that aggregates can exhibit life phenomena such as synthesis, decomposition, growth, and reproduction.

Life originated in "small ponds rich in organic salts such as ammonia and phosphorus, light, heat, electricity, and other related substances." The theory of the origin of life has always been a matter of debate in the scientific community. Life on Earth may have originated in freshwater ponds, rather than near deep-sea heat sources, as is widely believed in academic circles.

From ancient times to the present day, there are many theories that explain the question of the origin of life. For example, the Western theory of creation, the Chinese theory of Pangu opening heaven and earth, etc. However, it was not until the nineteenth century, with the advent of Darwin's book "The Origin of Species", that biological science underwent unprecedented changes, and at the same time, it also brought a glimmer of hope for mankind to reveal the eternal mystery of the origin of life, which is the modern theory of chemical evolution.

The chemical evolution theory of the origin of life was first confirmed by an American scholar Miller in 1953. That was in the early days, because the Earth contained a large amount of reducing primordial atmosphere, such as methane, ammonia, water, hydrogen, and the primordial oceans.

When lightning on the earth in the early days polymerized these gases into a variety of amino acids, and these amino acids, at room temperature and pressure, it may be locally concentrated, and then further evolved into proteins and other polysaccharides, as well as polymer lipids, which may germinate into life at a certain time, which is the process of life evolution described by Miller.
