Question

Mention the contribution of S.L. Miller’s experiment on Origin of Life.

Answer 1

Hint: Miller performed an experiment in 1953 to prove this concept. The conditions of primitive earth-high temperature, volcanic storms, atmospheric reduction comprising CH4, NH3, etc. were generated on a laboratory scale.

Complete answer:
First we should know about the origin of life to answer this question. Evolutionary biology is called the study of the history of forms of life on earth. Evolution is a phenomenon that contributes to heritable population changes spread over several generations that lead to the diversity of life on earth. Oparin and Haldane suggested that life naturally originated from non-living matter on earth, i.e. organic molecules (proteins, DNA, RNA). S.L Miller performed an experiment in laboratories where he established similar conditions to primitive environments, such as high temperature, environment reduction composed of NH3, CH4, etc. He developed an electric discharge at 800 ° C in the flask containing all of them. Organic molecules have been developed, such as amino acids. This confirms the above theory that organic matter life could have originated.
Experimental evidence for chemical evolution was provided by SL Miller's experiment. The findings of the experiment revealed that, around three million years ago, the first non-cellular life forms were formed. Experiments have also shown that there are non-cell biomolecules in the form of RNA, DNA, proteins and polysaccharides.

Note:A week later, the synthesis of amino acids was noted. Some researchers have seen complex compounds such as nitrogen bases, sugars, fats, and pigments in the flask. Meteorite research also showed the existence of related compounds. Life's chemical evolution has been more or less accepted.
