State two postulates of Orparin and Haldane with reference to origin of life.

Oparin and Haldane proposed that life originated from chemical reactions in an aqueous environment. The postulates proposed by them are:

1. The molecules present in the aqueous environment come together to form coacervates or aggregates.
2. Hydrogen gas served as a reducing agent while methane provided the hydrocarbon skeleton for the synthesis of organic compounds, and oxygen gas was absent.
