An autowave model of vesicle formation on the ocean surface

According to the hypothesis of the origin of life on Earth proposed by the coauthors of this publication [4–6], when an aerosol particle that was generated by bursts of air bubbles on the surface of an ancient ocean and was covered by a monolayer of amphiphile fell back on the surface it was transformed into a vesicle covered by a bilayer of amphiphilic molecules. The vesicle is considered as a cell prototype because it is in a thermodynamically nonequilibrium state caused by asymmetry of the distributions of ions and chiral components. In this work, the ocean surface layer is considered as an active medium that can be described by the Fitzhugh-Nagumo equations. A computational experiment showed that a stable vesicle covered by a bilayer of amphiphilic molecules can be formed under such conditions and that it submerges.
