I would like to see the scientific community come up with more specific parameters as to what would be considered: A. minor damage to the theory, B. major hit on the theory, and C. evidence that would make the theory most likely untenable. We do this for almost every other science, except evolution.
I think we do this for evolution as much as any other part of science. In any, the judgment of the severity of a “hit” is possible if you understand the relevant concepts. An understanding of the concepts lets one see what separates minor issues from fossil rabbits in the Precambrian; what’s a detail, and what’s central to the theory—some things would necessitate a modification, and some would cast the entire theory into question. Think of what it took to overturn any other well-established theory in history, or what it would take to overturn relativistic physics.
More generally, if you have a whole bunch of evidence that points to one conclusion, it should take something fairly extreme to substantially sway you away from belief in that conclusion and make you re-evaluate all the accumulated evidence. (And there’s a lot of evidencefor evolution.)
