There was no life on land so what did the rabbit eat?
Life on land started after the Cambrian - David will give the day month and year:)

A major reason a theory may be hard to falsify is that theorists are flexible and inventive. Theorists who are deeply and emotionally committed to evolution (as I also am) would not allow so trivial a thing as a Precambrian rabbit to make them throw out their baby.
A theory accounting for both Precambrian rabbit and pollen grains that I find appealing:
Precambrian life existed for about three billion years. We can argue that two billion is all that was needed to prepare Earth for air-breathers. So we have a billion to play with. It took only about a half billion for our kind to develop. A billion would be more than adequate for similar development to have taken place and then to have been wiped out in an extinction event. So the Precambrian rabbit, instead of falsifying evolution, would actually be evidence for double the amount of higher-form evolution!
Q: Why isn't there any other Precambrian fossil evidence for mammals? A: Only a very small fraction of Precambrian terrestrial sedimentary rock has survived the billion-plus years of tectonic and other geologic activity. What we have is not characteristic.
Q: Why don't we find evidence in Precambrian marine sediments of vertebrate-like animals with bones? A: Only a very small fraction of Precambrian marine sedimentary rock has survived the billion-plus years of tectonic and other geologic activity. What we have is not characteristic.
But once again, fossils appearing randomly in time would falsify evolution. Nothing could rescue the theory from such an observation.

One could just as easily say that calculating ancient ages for recently
formed pillow lava would kill the conventional model of radiometric dating.
But no, it didn't and hasn't, because the data-as-anomaly has been explained
by scientists as being an unreliable method due to various factors in the
composition of lava. YECs use this as a great example of why the science is
not only invalid but ad hoc and biased toward an old earth, but that doesn't
change the fact that the vast weight of evidence supports an ancient earth,
so the standard explanation holds in spite of this anomaly.
A rabbit in the pre-Cambrian would inevitably be explained as a geological
discontinuity (it actually came from the proper period, but geological
upheavals cast the fossil into pre-Cambrian strata); or as was mentioned,
some unknown and unforeseen rapid evolutionary branch that occurred at an
earlier date than previously believed; or the alien insertion of a rabbit
from some alternate multiverse; or some other explanation of the anomaly.
This is why I raised the point several months ago that in some ways,
evolutionary theory is presently unfalsifiable, because those who are
already committed to it will always be able to come up with some creative
(and probably untestable) hypothesis for explaining the anomalies. The
counter argument to this is the vast strength of consistent evidence for
radiometric dating, evolutionary sequences, etc. in general, because they
have passed so many potentially falsifying tests so far.

Michael,
Not for me. For what about all the evidence for evolution? Are you saying
it is so weak that a single rabbit fossil in the pre-cambrian throws it all
out? I think the evidence for evolution is to strong that such a fossil
would cause us to question our understanding of geological processes.

Rabbits would kill evolution. Period.
