Area of Science:

Origin of Life Studies
Molecular Evolution
Biochemistry

Background:

Understanding the evolutionary steps from simple molecules to complex life is a fundamental scientific challenge.
The role of specific biomolecules in the early stages of life's emergence requires detailed investigation.

Purpose of the Study:

To experimentally trace the evolutionary hierarchy from molecular to biological structures and functions.
To elucidate the central role of proteins in the sequence of life's emergence.
To explore the basis for the emergence of mind within the context of life's origins.

Main Methods:

Experimental tracing of the evolutionary sequence: molecular structure → macromolecular structure → protobiological structure → biological structure → biological functions.
Analysis of the role of proteins in the formation of nucleic acids.
Investigation of amino acid self-sequencing in protein formation.

Main Results:

The evolutionary pathway consistently involves proteins as a key intermediate.
Proteins were found to instruct the formation of nucleic acids.
Amino acid self-sequencing was identified as the instructional basis for protein formation.

Conclusions:

Proteins are central to the emergence of life, acting as instructional molecules for nucleic acid synthesis.
The self-sequencing of amino acids provides the foundational instruction for protein emergence.
Cellular membrane proteins offer a material basis for the emergence of mind alongside life's origins.
