Lipids have amazing properties. They can selectively allow certain molecules to pass through them. They can
also store energy in the form of electrical voltages across their surfaces which can be discharged to facilitate
reactions inside them. In some cases they can grow so big in size that they become unstable and split into
smaller spheres.
This is how the first crude proto-cells could have been formed on Earth with simple strands of RNA being
trapped within a lipid pre-cell.
