everything about cell membranes splitting would need to be encoded in the germ plasm of the embryo (because all cells derive from that one). Can you point to the information-encoding information in the germ plasm which is not in the nucleus? Everything we know about cell biology currently suggests that everything required for cell membranes is implemented by proteins controlled by regulated expression of DNA. For natural selection to operate directly on membranes would be a fantastic discovery but would require some pretty challenging experiments to demonstrate convincingly.
