Well, actually it seems that if any of the three candidates you posited as possible agents in originating life were "the originating force", then that force may have acted at other times.

There is no postulate in biology that abiognesis was only possible in the past and is not possible now.

It seems that it would be quite relevant to evolution, if it were subjected to such a force even once after the "origin".

How would it be relevant? Be specific.

How would it be relevant? Be specific.

My thinking is that if "a force that can originate life" acted at more than one point in time, then the time sequence now used is quite suspect of being accurate as a framework in which evolution occurs.

Specific example: If there are other "Burgess shale" deposits yet to be discovered that occurred at later or earlier times than we believe the actual Burgess shale to represent, that would effectively challenge the current timeline of evolution. That seems quite relevant, since time is most assuredly a key component of "change over time".
