Diagram of biomolecules between sheets of mica in a primitive ocean. The green lines depict mica sheets and the grey structures depict various ancient biological molecules and fatty vesicles. In the ‘between the sheets’ mica hypothesis, water may have moved in and out of the spaces between stacks of sheets, thereby forcing the sheets to move up and down. This kind of energy may have ultimately pushed biological molecules and/or fatty acids together to form cells. Credit: Helen Greenwood Hansma, University of California, Santa Barbara.

Because mica surfaces are hospitable to living cells and to all the major classes of large biological molecules, including proteins, nucleic acids, carbohydrates and fats, the “between the sheets” mica hypothesis is consistent with other well-known hypotheses that propose that life originated as RNA, fatty vesicles or primitive metabolisms. Hansma says a “mica world” might have sheltered all the ancient metabolic and fat-vesicle and RNA “worlds.”
