|
Newly formed organic molecules polymerized to produce larger molecules and macromolecules

Detailed explanation-1: -Chemical evolution refers to changes in things that need not be capable of reproduction. Examples could be individual molecules, or entire chemical systems. A chemical system is a group of molecules that interact with each other.
Detailed explanation-2: -The modern theory of chemical evolution is based on the assumption that on a primitive earth a mixture of simple chemicals assembled into more complex molecular systems, from which, eventually came the first functioning cell(s).
Detailed explanation-3: -Chemical and organic evolution are two components of the evolutionary process. Biomolecules change over time during chemical evolution while species change over time during the organic evolution. This is the key difference between chemical and organic evolution.
Detailed explanation-4: -The theory of chemical evolution says that the complex organic molecules were formed from the simple molecules by the chemical reactions that occurred in the oceans during pre-historic age. This was the first step in the development of life on earth. This theory was based on the experiment done by Miller and Urey.
