The late S.J. Gould’s model was “diastrophe” — diastrophe was the punctuation mark in the punctuated equilibria.

Yes but..... once the effect is developed it is not really to hard to find another cause

Except the moths don’t usually land on tree trunks in nature

You don't suppose the rest of the trees were affected by the soot of the coal age do you? And yes, birds for which the camo would matter, are not the only predator that east moths, but they do eat them.

Possibly. The moths roost on the underside of small branches among the leaves of the trees. Its unclear that their coloration had a significant effect on their chances for survival. The experiment was supposed to show that birds were able to see the lighter moths easier and were eating them at a greater rate. This was supposed the be the cause of the increase in darker colored moths. The problem is that the experiment placed the moths in unnatural positions on tree trunks where they were exposed to the birds. The experiment was flawed and should not be used as an example of natural selection.

“Way to cover all the bases. Then no matter which one pans out, you were right! “

That’s what makes the TOE just an idea and not a theory. There’s no way to falsify it.

“Interesting hypothesis. Can you describe an experiment to prove or disprove the hypothesis? “

Let me know when you get a good answer on this one. I’ve heard some lame excuses for experiments but none under controlled conditions which would prove anything. They try to use adaptation as the example of the TOE but that does not show speciation, in fact it shows the opposite.

Darwin proposed some, I hear, but that sort of thing isn’t allowed any more.

For every thing that Darwin said would falsify his theory, Darwinists have found some way to excuse it.
