The theory of abiogenic peptide membranes is an intriguing idea and it appears plausible. I suspect mica crystals may also play an important role. Under a microscope, weathered mica crystals look like the pages of a book that has been left outside in the rain. The spaces between the crystal layers could provide an undisturbed environment where the biochemical reactor could assemble favorable chemicals filtered through a peptide membrane. The mica crystal surface could also serve as a “bread board” for assembling amino acids in the proper order to create a self reproducing protein.

Protoviruses are believed to be long extinct but I suspect they can still be found safe inside the layers of mica crystals. Their small size and long generation times would make it nearly impossible to observe their presence so I have no hope of ever hearing that a protovirus has been discovered.
