Solution
The concept of chemical evolution is based on possible origin of life by combination of chemicals under suitable environmental conditions.
Explanation:
Chemical evolution proposes that simple chemicals combined through a sequence of reactions to form complex organic molecules and eventually early life. Solar radiation was one possible energy source, but it alone does not define the theory.
