Does it assert that volcanic ash at Mistaken Point does not preserve as fine detail
as the Burgess shale? Why not?
Both are listed along with the Chengjiang as Konservat-Lagerstätten:

For what? certainly not for sci.bio.paleontology.

Why? because you are enamored of an exchange you

A wretched opinion it was too.

Why "notably"? you seem to not want to talk about the rest of the "post"
(article) at the end of your post.
But the bottom line is, you are putting a huge spin on what Matzke told you. See below,
where he talks about some simple mistakes students and some
biologists make in interpreting cladograms, and why rotations
can trip some up. Here is another on a slightly higher level.
If you look at the two cladograms Berlinski provides, the second makes it *look* like
there is a synapomorphy involving A and B, while the first makes
it look like there is a synapomorphy between A and a clade
in which B and C are synapomorphic. Perhaps neither is true,
but perhaps one interpretation is true and the other false.
The thing is, cladograms don't distinguish between a case where
two new species are formed, and the more common case
where a new species splits off from an old one while the
old one continues to be in stasis. This is right at the foundation of
Punctuated Equilibrium theory.
This may be why you dislike PE: it spoils the pretty "legal fiction"
of two new taxa coming off at each node.
But back to what Berlinski actually said. He was talking about
direct ancestry, and these were cladograms, not phylograms,
and so the first could really have A being ancestral to B,
if there were 0 apomorphies between A and the LCA of A and B.
But the second cladogram makes such a possibility look remote.

Now there's a fine example of trash talk. There are lots of
ways to misread cladograms, and you are pretending that there is
"someone else" to whom Berlinski was referring when he was obviously
lecturing about one kind of misreading into which plenty of people could fall.
Matzke tried to make it clear to you that there are lots of people who fall into
misreadings of cladograms [see below], but you are ignoring that in order
to score worthless debating points against me and Berlinski.

As jillery loves to say, that's a distinction without a difference.
You converted a tidbit that Matzke found "hilarious" into something quite different
with the comment that Glenn quoted from you.
> That was the subject of the discussion at Sandwalk.
How egocentric of you to talk about a tiny fragment of the comments
section, and nothing about Moran's article at all! And to pay so little
attention to what Matzke told you [see below].
> I asked a question about it,
About a comment by Matzke ("NickM") that mystified you,
and you had to ask twice about it. Matzke was
surprised that you weren't familiar with the old rotation business:
"Hi John -- I'm not getting what you're not getting. It is common for e.g. students (and certain sorts of insufficiently educated biologists) to misinterpret cladograms (usually upwards-pointing ones) by giving significance to the left-to-right order of the tips at the top."
Matzke may have been unaware of how little, if any, teaching
experience you have had on that level, but he went on to give you quite a long talk instead
of the misleading description that you are giving here:
> I was informed of what was said,
> I looked, and yep that's what he said.

Feel free yourself, if you take your use of "notably" up there seriously.
I'd like for you to address "what he said" about the rotation,
instead of talking all around it.
