And if it had been the other way around, what then? Perhaps the environment could furnish clues; long tails might blend in with vegetation with long stalks, etc. and there is no falsification of natural selection, but an "additonal confirmation." The popular literature is full of alleged counterexamples to natural selection that get shot down with more sophisticated arguments.

In other words, the alleged falsifications themselves get falsified.

This says nothing about how it could possibly be falsified. Nor have I seen anything on this thread that says how it could be falsified.

So, let's see a hypothetical observation that you would consider as falsifying it. And, since you seem to be a lot more precise about things than most people here, Howard, you might want to begin with a definition of natural selection that goes beyond what I call the "Darwin of the Gaps" definition:

"The __________ that did/could/are __________ had a survival advantage over the ones

that didn't/couldn't/weren't

and so they are the ones we see today."

When I introduced this, Howard, I called it "The default, one-size- fits-all, totally unfalsifiable naturalistic explanation for any and all biological phenomena."

[I should add that there are other explanations, like genetic drift, for some biological phenomena. But a sufficiently gung-ho devotee of natural selection might confine himself to just the above kind of argument.]

You participated on the thread where I introduced it, but I had boycotted you for so long that you may have stopped reading my posts, so you may have overlooked this one.

Had the thread been started two months later, I would have responded

to your first post on the thread, because your old buddy PZ Myers was the focus of attention.

Now HERE, you give a very simple way gravity could be falsified. Can you do it for natural selection? > IOW, NS is a good description > of what happens in the world of empirical reality.

Gosh, you allege a tight link here ("IOW, NS...") but you suddenly revert to talking about gravity and never make a real connection.
