Unveiling Life's Origin: Oparin-Haldane Hypothesis Demystified

Step 1 of 2

The Oparin and Haldane hypothesis was also based on the heterotroph hypothesis. The heterotroph hypothesis, according to Oparin-Haldane, required three major steps for the origin of life:

• The non-biological processes supplied the organic molecules.

• These molecules are then assembled into molecules like proteins and nucleic acids.

• These molecules are then organized into a system that replicates itself.

These steps suggested that the non-living molecule changes to a living molecule at each step.
