The experiment to confirm the origin of life from inanimate matter was performed by
The correct option is D Stanley Miller and Harold C. Urey
The correct option is D:
Explanation of the correct option:
- The Miller and Urey experiment proved that life emerged from inanimate substances. They created the atmosphere with chemicals including ammonia, methane, and hydrogen sulfide but no oxygen in the experiment.
- The atmosphere is comparable to that which existed on the early earth. The lighting was stimulated by keeping the temperature constant at 100 degrees Celsius and sparks were sent through the mixture.
- A certain quantity of carbon from methane had been transformed into simple carbon molecules like amino acids after a period of time.
- Proteins are the molecules that support life in their most basic form, while amino acids are the precursors to proteins.
Explanation of the incorrect options:
Option A:
Lamarck proposed three theories i.e. inheritance of acquired traits, increase in complexity, and use and disuse of organs.
Option B:
August Friedrich Leopold Weismann researched the development and evolution of biological features in a variety of creatures, primarily insects and aquatic animals.
Option C:
The discovery of population genetics was Haldane's most important foundational scientific contribution.
Final answer: The experiment to confirm the origin of life from inanimate matter was performed by Stanley Miller and Harold C. Urey.
