An otherwise excellent analysis. This conclusion is where I think you stray.
When the OPERA experiment on neutrinos first announced its results, other than the media and those who did not understand the strength of the theory, did any of you seriously think "We have to entertain grave doubts about relativity"? No.
Me neither. But imagine being confronted with a
griffin. For fuck's sake. Biology is actually simpler than physics. An experiment suggesting that superluminal travel is possible is not quite on the same plane as
finding a fucking griffin. If we had one in a zoo, then it would not be subject to the same
sort of question as whether we'd accurately measured the speed of the neutrino. Either it is a fucking griffin or it is not a fucking griffin.
But if the OP is saying "This thing, this griffin, appears. Does this disprove evolution?" Given the strength of the theory, the body of evidence, the overwhelming facts ... no ... this thing has not disproved evolution. Frankly, it doesn't even give any serious challenge. No grave doubts.
Well then, what would?
As I have said, it's something of a judgment call. Very well then, what is the
least thing that would cause you to have "grave doubts"?
For me, an actual fucking griffin would do it. But what would do it for you?
