Chemical evolution refers to the process by which simple organic molecules gradually form more complex structures over time.
This concept is fundamental in understanding the origin of life, as it describes how simple molecules like amino acids and nucleotides could have formed more complex macromolecules such as proteins and nucleic acids.
Chemical evolution is driven by various factors, including environmental conditions, energy sources, and catalytic surfaces, which facilitate the formation of complex molecules.
It is distinct from biological evolution, which involves changes in living organisms over generations, as chemical evolution pertains to prebiotic chemistry.
Understanding chemical evolution helps scientists explore how life might have originated on Earth and potentially on other planets.
