Abundant energy sources facilitated the synthesis of organic molecules from inorganic ones, enabling molecules to replicate and evolve into cells.
Energy sources: Abundant energy from sources like lightning allowed for the reductive synthesis of organic molecules from inorganic precursors.
Mechanism of replication: Molecules gained the ability to make copies of themselves, which is crucial for the evolution of life.
Complex molecule interactions: As the 'soup' of organic molecules became concentrated, interactions led to the emergence of self-replicating molecules and eventually the evolution of cells.
