3. How does chemical evolution explain the origin of life on Earth?

Answer and explanation:

The theory of chemical evolution is one of the most important theories for understanding the origin of life.

This theory admits that life is the result of reactions envolving inorganic compounds that have combined and formed some organic molecules, such as amino acids, nitrogenous bases and fatty acids.

The organic molecules were then combining, until the first particles with some type of metabolism appeared.
