Write the Oparin and Haldanes hypothesis about the origin of life on Earth. How does meteorite analysis favour this hypothesis ?

Answer 1

Haldane theory of chemical evolution states that life originated from pre-existing, non-living organic molecules. In 1953, S.L. Miller observed the formation of amino acids from hydrogen and water vapour at 800-degree centigrade.

When the meteorites were analysed, it was observed that the presence of similar compounds was confirmed which conclude that a similar process is going on elsewhere in the space.
