Precisely. There is no conceivable evidence that can disprove the
theory of natural selection. The theory of natural selection makes
zero predictions.


That's not true, as I've pointed out to you at least twice before.
Natural Selection predicts that some species will become extinct, and
that species will tend to diversify.


I don't think that's true. Extinction of species is quite outside the
bounds of natural selection,

Darwin thought that as one result of the operation of Darwinian
natural selection, certain species would be driven to extinction.

unless you are extending it to include
species selection, and even then it only predicts that if you assume all
sorts of conditions. And "will tend to diversity" is too vague to count
as a prediction. Further, diversification (assuming you mean
branching/speciation) may not have all that much to do with natural
selection. If you want it to, you have to assume more conditions, in
particular disruptive selection as a major cause of speciation.
Speciation, however, can be explained without recourse to selection at
all: just the long-terms effects of geographical isolation. Ditto with
extinction: even if there were no selection, there would still be
extinction, even if only as a result of chance.

And this is what we see in nature.


Weak and invalid claims, I'm afraid. Natural selection however does make
predictions, but I don't think there are any general predictions. It
makes predictions about outcomes in specific cases in which various
parameters are known, and can also be used to make statistical
predictions about what will tend to happen in repeated situations where
the parameters are less well known. Natural selection is used to make
predictions all the time in the literature, but not these grand, global
predictions that both you and David seem to want.

The theory of natural selection makes a so-called "crazy quilt"
prediction about one pattern we should see in the fossil record. That
prediction does not match up with observation.

Hsü claims that competition between species isn't the only cause of
extinction. But so what? Are you claiming that such competition *can't*
cause extinction?

unless you are extending it to include
species selection, and even then it only predicts that if you assume all
sorts of conditions. And "will tend to diversity" is too vague to count

This seems to be a little bit of confusion of levels on Darwin's part.
What's operating in such cases is not natural selection as we commonly
understand the term, but interspecific competition (which we might
perhaps call species selection). Perhaps, as Gould claimed, Darwin
really was proposing a multi-level selection theory.

unless you are extending it to include
species selection, and even then it only predicts that if you assume all
sorts of conditions. And "will tend to diversity" is too vague to count

Goldschmidt was confused. Are you confused in the same way as
Goldschmidt? I'm confused in one way: I don't understand what "crazy
quilt" is supposed to mean in this context.
