Subject: In the News: A Complex Tail, Simply Told
From the article:
----------------------------------------------------------------
By Jennifer Cutraro
ScienceNOW Daily News
17 April 2007

One of evolutionary biology's greatest challenges is deciphering the origins
of complex structures. Now, scientists have unraveled the steps in the
evolution of the bacterial flagellum, a tiny, whiplike structure used in
swimming and host invasion. A new study shows the flagellum is the result
of successive duplications of a single gene in the ancestor of today's
bacteria, a finding that not only answers an important question about the
evolution of complex structures but also provides additional ammunition to
counter arguments from evolution's foes.

Sounds interesting.  I look forward to what the bloggers have to say about
it, and to seeing this paper online.  Or maybe I'll make a trip to the local
med-school library and xerox it.

But I have to say that the ScienceNOW article didn't give me a very warm
feeling about this.  Especially the picture of what I am pretty sure is
not a bacterial flagellum.  I'm not an expert, but it looks more like two
eukaryotic flagella (or maybe four) in a dinoflagellate.

Nick Matzke has an article on what appears to be the same paper at the
Panda's Thumb.  He sounds a note of caution, noting that, based on
what he knows, the claim that the entire flagellum (as opposed to
significant parts of the flagellum) originated from duplications of a
single gene is not tenable at all, and that while this is an important
piece of researching confirming some earlier ideas about flagellar
evolution, it seems to over-hype the significance of these results.

And here is a blogger who has bad feelings about all this instant blogging.

Even if you are not interested in flagella, it is worth dipping into this
maelstrom just to get some feeling for how science is done, both the old way,
and the new web-based way.

It seems like a no brainer that all the parts of the flagellum were

probably just talking about certain relationships between the parts.

I'm not qualified to analyse the scientific question, which at once is
both on the "bleeding edge" of research and, I suspect, only being
looked at this decade because of intelligent design claims.  But the
"authority figures" involved who are criticising the work appear to be
amongst those whose prejudice, if they were acting on prejudice, would
be to incline to favour the argument of the paper and even not to
scrutinise it minutely, since it points in the direction that they
like.  So, on the other hand, they must be fairly sure of their
sceptical position, to make a stronger statement than "I have some
misgivings, I don't follow the argument as compellingly persuasive."
To say that it's plain wrong.

If it /is/ wrong, it's going to be interesting and educational to see
how fast and how well a corrective word catches up with the original
exciting news.  And in any case creationists will have a field day.
They're still throwing erroneous embryo sketches and Piltdown Man in
your face, all these years later.

The work is quite interesting, although I'm not sure how mankind
benefits from discoveries in this precise area.

Elsewhere, I was looking at web page discussions from a little while
back when chimpanzee DNA was sequenced, and some creationists are on,
like, Go ahead then, I guess you're going to say that this is proof
that humans really are related to chimpanzees", and the majority of
people on the science side are going, "proof that... what??  how the
heck is that even a question?"

There's no /need/ to twist the intelligent designists' flagellum.  The
argument with intelligent design has been over for a long, long time.

Judge Jones said scientists determine what science is.  It's a pity that you
are intellectually incapable of comprehending what the Dover decision meant.
But please do keep misrepresenting it.  It only confirms the level of
depravity that you operate at.

No, that does not seem to be what they were talking about.  They really do
suggest, based on weak, but suggestive evidence, that a set of 'core'
protein components (24 of them) evolved from a single protein.

Well, actually, in the abstract, they say it a little more weakly

  Within a genome, many of these core genes show sequence similarity
  only to other flagellar core genes, indicating that they were derived
  from one another, and the relationships among these genes suggest
  the probable order in which the structural components of the bacterial
  flagellum arose. These results show that core components of the bacterial
  flagellum originated through the successive duplication and modification
  of a few, or perhaps even a single, precursor gene.

A few precursor genes, maybe.  But I agree that it seems like a no-brainer
that they have to be wrong that there was a single precursor gene.

But that still leaves the question as to why the suggestive evidence
for a single gene exists.  Hmmmm.  I wonder what would happen if you used
their methodology to look at a set of eukaryotic nuclear genes all targeted
at the same organelle.  Many of these genes would have at least some partial
homology because they would all contain similar 'signal peptide' sequences.
I wonder if something like this is involved here.

Would it make more sense to take the issue to a school board or

(the issue arises when, among other occasions, it is necessary to
decide whether some alleged new forensic technique is generally-

deciding whether something is generally-accepted science or, in the
Dover case, religious dogma with the serial numbers filed off, is a
different matter from settling a particular scientific question in an
