Does anyone know of a solid example of a biological membrane that arises de novo, rather than by the extension of a pre-existing membrane?

Let me see if I understand the Question correctly: Are you suggesting, Talmudically, that perhaps every closed membrane found in the totality of modern cells amounts to a pinched-off fragment of a single ur-membrane, continuously grown lipid-by-lipid, that formed billions of years ago?
If so, we might see genes and other cellular machinery as a way that The Membrane has discovered to help extend itself.
