If you'll pardon my intrusion, this is a category error.
A scientific theory, according to Popper's naive falsifiability, should be falsifiable. However, is 'abiogenesis' a scientific theory? I would argue that it is not. It might be a research program. Physics is indubitably science, but it is not falsifiable.
But I'm interested in hierarchial Popperism. I take it that hypotheses that are not falsifiable may be science?
