Detailed explanation-1: -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-2: -Conclusions: Complex Evolving Systems This volume outlines how three distinct stages of chemical evolution – prebiotic, biological, and human-directed – have framed Earth’s 4.5-billion year history. Each stage saw significant chemical complexification driven by varied selection processes.
Detailed explanation-3: –Russian scientist, Aleksandr wrote in “The origin of Life on Earth” that in the first stage of chemical evolution, molecules in the environment formed simple organic molecules such as amino acids.
Detailed explanation-4: -A third theory of life’s origin is known as chemical evolution. In this idea, pre-biological changes slowly transform simple atoms and molecules into the more complex chemicals needed to produce life.
