The Stages of the Origin of Life on Earth According to the Theory of Biochemical Evolution

The stages of the origin of life on Earth according to the theory of biochemical evolution are as follows:

A. Formation of membranes on the surface of coacervate droplets. B. Emergence of the self-replication process. C. Accumulation of proteins in the primary broth and formation of coacervates. D. Formation of simple organic compounds from inorganic substances in the primary ocean.

The correct sequence of these stages is: D-C-A-B.

Here is a brief explanation of each stage:

D. Formation of Simple Organic Compounds from Inorganic Substances in the Primary Ocean

In the early Earth, the primary ocean contained various inorganic substances. Through chemical reactions, these inorganic substances combined to form simple organic compounds, such as amino acids and nucleotides. This stage is believed to have occurred through processes like Miller-Urey experiments, where the conditions of the early Earth were simulated to observe the formation of organic compounds [[1]].

C. Accumulation of Proteins in the Primary Broth and Formation of Coacervates

As the simple organic compounds accumulated in the primary ocean, more complex molecules, such as proteins, started to form. These proteins accumulated in the primary broth and eventually led to the formation of coacervates. Coacervates are droplets that contain a concentrated mixture of organic molecules surrounded by a membrane-like structure. This stage is important because it represents the formation of the first organized structures that could potentially exhibit some characteristics of living systems [[2]].

A. Formation of Membranes on the Surface of Coacervate Droplets

In this stage, membranes started to form on the surface of coacervate droplets. These membranes are believed to have been formed by the self-assembly of lipids, which are organic molecules that have hydrophilic (water-loving) and hydrophobic (water-repelling) regions. The formation of membranes is crucial because it allowed for the separation of the internal environment of the coacervate droplets from the external environment, creating a semi-permeable boundary [[3]].

B. Emergence of the Self-Replication Process

The emergence of the self-replication process is considered a major milestone in the origin of life. It is believed that certain molecules, such as RNA, were able to catalyze their own replication. This self-replication process allowed for the accumulation of genetic information and the potential for heredity. The ability to replicate and pass on genetic information is a fundamental characteristic of living systems [[4]].

It's important to note that the theory of biochemical evolution is still an area of active research, and there are various hypotheses and models proposed to explain the origin of life on Earth. The stages mentioned above represent one possible sequence based on current scientific understanding.
