Iron sulfide bubble hypothesis

WebIron-sulfide Bubble Hypothesis. Proposed that evolution of lipid membrane was a crucial step for the origin of life. Lipid molecules spontaneously formed liposomes (membrane enclosed spheres) Liposomes could then form around organic molecules and act as membranes that separated these molecules from the environment.
