How Did Life Begin? Biochemical Evolution On Chemical Surfaces

A new theory suggests that small organic molecules may assemble into self-replicating biomolecules on the surfaces of silica-rich minerals, providing a potential mechanism for life's origin. Geophysicist Joseph V. Smith proposes that organophilic zeolites could have concentrated and protected these organic compounds from destruction.
