摘要
In the classical 'prebiotic soup' model of the origin of life, biomolecules are seen arising abiotically on the Earth and then Interacting randomly in solution to form proto-cells. This model has encountered increasing difficulties, however, and recently several alternatives have keen proposed. In some of these models, it is postulated that proto-cells evolved from simple biomolecular complexes originally attached to mineral surfaces, especially those of pyrite. The subsequent evolution of these complexes has been likened to embryonic development.
