Let me see if I can follow this. First, Martin's claim:
"Menton is a liar. He cannot possibly know anything about the pelvic fins of Tiktaalik. The two papers describing Tiktaalik offer absolutely no descriptions of the pelvic fin skeletons or girdle. I've seen the material first-hand and there are no such details of the pelvic fin." [Martin Brazeau, "Dr. David Mention is a Liar." The Lancet, 2007]
I believe this is the Menton passage in question:
"The hind limbs [of tetrapods] in particular have a robust pelvic girdle securely attached to the vertebral column. This differs radically from that of any fish including Tiktaalik. Essentially all fish (including Tiktaalik) have small pelvic fins relative to their pectoral fins." [David Menton, "Tiktaalik and the Fishy Story of Walking Fish." Answers in Genesis, 2007]
And this is a passage from a Menton footnote of a Nature article by Ahlberg and Clack that supports Menton's statement:
"In some respects, Tiktaalik and Panderichthys are straightforward fishes: they have small pelvic fins, retain fin rays in their paired appendages and have well-developed gill arches, suggesting that both animals remained mostly aquatic. In other regards, Tiktaalik is more tetrapod-like than Panderichthys. The bony gill cover has disappeared, and the skull has a longer snout . . . The fossils [of the Tiktaalik] are earliest Late Devonian in age, making them at most 2 million or 3 million years younger than Panderichthys. With its crocodile-shaped skull, and paired fins with fin rays but strong internal limb skeletons, Tiktaalik also resembles Panderichthys quite closely." [Ahlberg & Clack, "A Firm Step From Water to Land." Nature, 2006]
Wow, OK... This is going to take some deconstructing.
Reading the Ahlberg&Clack essay, they cite "The pelvic fin and girdle of Panderichthys and the origin of tetrapod locomotion", Boisvert, C. Nature 438, 1145–1147 (2005).
That paper came out in 2005, prior to the Tik papers, and ONLY mentioned Panderichthys.
Let me guess - in your desperation to protect YEC Menton, you looked at one of the papers he mentioned (but not the actual Tiktaalik papers?), keyword searched "pelvic", and thought you found a winner? Standard YEC "research" in action...
Anyway...
Here are the two Tiktaalik papers Ahlber & Clack refer to:
Nature. 2006 Apr 6;440(7085):757-63.
A Devonian tetrapod-like fish and the evolution of the tetrapod body plan.
and
Published: 06 April 2006
The pectoral fin of Tiktaalik roseae and the origin of the tetrapod limb
What is that??? PECTORAL fin???
Uh oh - I spoke too soon -
Pelvic girdle and fin of Tiktaalik roseae
Neil H. Shubin, Edward B. Daeschler, and Farish A. Jenkins, Jr.
Never mind - that didn't come out until 2013, but in it we see:
"The discovery of pelvic material of the finned elpistostegalian, Tiktaalik roseae, bridges some of these differences. Multiple isolated pelves have been recovered, each of which has been prepared in three dimensions. Likewise, a complete pelvis and partial pelvic fin have
been recovered in association with the type specimen. The pelves of Tiktaalik are paired and have broad iliac processes, flat and elongate pubes, and acetabulae that form a deep socket rimmed by a robust lip of bone. The pelvis is greatly enlarged relative to other finned tetrapodomorphs..."
So, I can only conclude sloppy editing in the Ahlberg & Clack essay, since the description of the pelvic fins did NOT get published for a few more years. But Menton is a brilliant YEC scientist, and surely such a person, whose goal after all was to demolish the relevance of Tiktaalik with the TRUTH - would not base his scientific rebuttal on the 'preview' essay in Nature, rather than the 2 actual publications in that same issue.... Would he?
Apparently so.
Nice try, but nope - Menton fudged it.
The size of the pelvic girdle of the Panderichthys (and thus, the Tiktaalik)
Umm... What?
They are 2 different creatures - but cute sleight of hand there, champ.
was determined from this article, which is footnoted in the Ahlberg & Clack article:
"The pelvic girdle itself is small: it measures 3.5 cm for a 90.5 cm long pre-pelvic body, corresponding to 3.86% of the body size as compared with 5% in Eusthenopteron and 7% in Acanthostega (measured from reconstructions)." [Catherine A Boisvert, "The Pelvic Fin and Girdle of Panderichthys and Theorigin of Tetrapod Locomotion." Nature, 2005]
The pelvic fin and girdle of Panderichthys and the origin of tetrapod locomotion
So... You don't know what footnotes are, got it. Those are called citations, by the way...
It is so weird - you actually looked up the Boisvert article - heck you provided the title!! but apparently ignored it, and still made 100% unwarranted assumptions and foolish conclusions (in which you conflate 2 different organisms) all to try to prop up your YEC hero.
NEXT!
These are Menton's footnotes:
1. Daeschler, E. B., N. H. Shubin, and F. A. Jenkins, 2006. A Devonian tetrapod-like fish and the evolution of the tetrapod body
plan. Nature 440(7085):757–763.
2. Ahlberg, P. E. and J. A. Clack, 2006. News and Views. Nature 440(7085):747–749.
The Boisvert, C. A. reference was footnoted in both the Daeschler, E. B. and Ahlberg et al reference.
Yeah, those are citations, not footnotes, but thanks.
Now, where did Menton go wrong? What am I missing?
See demolition above.
Oh - weird that you totally omitted his rather asinine claim about bony connections to the axial skeleton. That was wise (but not clever) of you to omit it.
