Life could have arisen through a series of organic chemical reactions that produced ever more complexbiochemical structures. They proposed that common gases in the early Earth atmosphere combined to form simple organic chemicals, and that these in turn combined to form more complex molecules. Then, the complex molecules became separated from the surrounding medium, and acquired some of the characters of living organisms. They became able to absorb nutrients, to grow, to divide (reproduce), and so on.. This statement belongs to:

“Life could have arisen through a series of organic chemical reactions that produced ever more complexbiochemical structures. They proposed that common gases in the early Earth atmosphere combined to form simple organic chemicals, and that these in turn combined to form more complex molecules. Then, the complex molecules became separated from the surrounding medium, and acquired some of the characters of living organisms. They became able to absorb nutrients, to grow, to divide (reproduce), and so on.". This statement belongs to:

A	Theory of biochemical evolution
B	Community clay
C	RNA world
D	Spontaneous origin

Explanation:

Detailed explanation-1: -The model of Neo-Panspermia. The Neo-Panspermia model proposes that meteors and/or cosmic dusts deliver necessary BBLs for generating life, after the formation of Earth’s ocean and atmosphere, and constantly do so even today.

Detailed explanation-2: -The experiment was a success in that amino acids, the building blocks of life, were produced during the simulation. The finding was so significant that it kick-started an entirely new field of study: Prebiotic Chemistry.

Detailed explanation-3: -major reference In the 1920s British scientist J.B.S. Haldane and Russian biochemist Aleksandr Oparin independently set forth similar ideas concerning the conditions required for the origin of life on Earth. Both believed that organic molecules could be formed from abiogenic materials in the presence of…

Detailed explanation-4: -Oparin and Haldane proposed that the first form of life could have come from pre existing living organic molecules.
