Question

Who proposed that the first form of life could have come from pre-existing, non-living organic molecules?
A) SL Miller
B) Oparin and Haldane
C) Charles Darwin
D) Alfred Wallace
E) Hugo de Vries

Answer 1

Hint:Abiogenesis says that the initial form of life could have evolved from non-living, pre-existing organic compounds. The study of abiogenesis intends to discover how pre-life biochemical reactions gave beginning to live under circumstances strikingly distinct from those on Earth now.

Complete answer:
Before we find the correct answer, let us understand a little more about abiogenesis. Abiogenesis is the belief that life originated from non-living more than 3.5 billion ages ago on Earth. Abiogenesis suggests that the first life-forms formed were very easy and by a continuous method became increasingly complicated.

>Option A: The Miller-Urey research produced the first proof that organic compounds required for life could be developed from inorganic elements. Therefore, this is an incorrect option.
>Option B: The law of abiogenesis was introduced by Oparin and Haldane. It says that life could have evolved from pre-existing non-living organic compounds (e.g. protein, RNA, etc.) and that form of life was led by biochemical development, i.e. development of different organic compounds from inorganic components. Therefore, this is the correct answer.
>Option C: Charles Darwin introduced the theory of survival of the fittest. Here, fitness eventually indicates generative fitness. Bions which are a more considerate fit in an atmosphere give more offspring than others. Therefore, this is an incorrect answer.
>Option D: Alfred Russel Wallace was a biologist who alone introduced the concept of progression by natural selection. Therefore, this is an incorrect option.
>Option E: Hugo de Vries put forward the concept of progression called mutation concept. He thought that mutation produces evolution. Variations are irregular mutations that are unplanned and directionless. Therefore, this is an incorrect option.

Thus, the correct answer is option (B) Oparin and Haldane.

Note:The Oparin-Haldane concept implies that life began through biochemical means of particles that joined to produce compounds. Molecules reacted to create organic and inorganic molecules. Organic molecules combined to create all kinds of macromolecules which combined to create the first form of cells or life.
