Question

What is the difference between chemical evolution and organic evolution ?

Answer 1

Hint:Evolutionary biology is the study of history of life forms on earth. This is a story of origin of life and evolution of life forms or biodiversity on planet Earth in the contents of evolution of earth and against the background of evolution of the universe itself.

Complete answer:
>The formation of complex organic molecules from simple inorganic compounds and then formation of complex molecules such as amino acids from simple organic compounds is called chemical evolution.
>Whereas organic evolution occurs due to change in species which generation after generation Such as new characters or some chemical change such as the conversion of ribonucleic acid to deoxyribonucleic acid in organisms as a genetic material . And this takes time to accumulate to form a new species .
>It is a very slow process hence it cannot be proved in the laboratory but can be proved naturally since in bacteria it can be proved as their generations are short lived .
 It involves the evolution of organic compounds such as proteins , for example the first genetic material was RNA and then slowly it became DNA .

Additional information :
>The first non cellular form of life could have originated 3 billion years back .
>They would have been giant molecules such as RNA , proteins and polysaccharides.This capsule reproduces their molecules perhaps .
>So mostly it is said that the first form of life arose slowly through evolutionary forces from non-living molecules and is accepted by the majority .

Note:The first cellular form of life did not possibly originate till about 2000 million a year ago.
 We can also say that chemical evolution held before organic evolution.Or in other words organic evolution is the consequence of chemical evolution.
