Compare the implications of the protein-first, RNA-first, and membrane-first hypotheses for the evolution of the first living cell. Introduction: There are many hypotheses regarding the origin of life. Billion years ago, the Earth was very much different from today, with enormous amounts of energy. The oceans contained lots of organic compounds created by inorganic processes. This process led to the building of more complex molecules. The nucleic acids form a pre-cellular life enclosed in a lipid-protein membrane, which resulted in the formation of the first cells.
