Origin of Life

The scientific field studying how life on Earth arose from non-living matter, in which the preference for single chirality is one of the central puzzles.

The chiral amplification mechanism provides a hypothesis that early Earth chemical processes may not have needed an external force to select chirality: a chance small perturbation could gradually establish a molecular pool of single chirality through chiral amplification.

Chiral amplification and autocatalytic mechanisms provide important clues for understanding the origin of homochirality in the origin of life, and are regarded as a bridge connecting chemistry and origin-of-life research.

At the dawn of life on Earth, it may have been precisely some accidental chiral fluctuation that was captured and amplified by an autocatalytic mechanism, thereby laying the foundation for the uniform chirality of biomolecules today.

The Hajjai reaction itself requires an anhydrous environment and special zinc reagents and could not have occurred directly on the early Earth, but it proved that single chirality can arise and grow on its own through chemistry.

Modern theory holds that the weak parity-violation effect in the universe or circularly polarized light from cosmic rays may have provided an extremely minute chiral seed for the early Earth's chemical environment.
