Just posted this to Pharyngula at the “An ontogeny of toilet drain behavior” thread

Very nice from Dr Fleury to finally inform us of what L2/R2 could be. Never late to do well. The funny thing is that he commented here but haven’t send me a message about it! That’s weird. I’m asking for evidence concerning [...]

geometry

I’m greek and during my young years I was feed a lot of geometry. You know how it is, national pride for the ancestors, especially under a military junta. So, I’m quite sensible when one presents geometrical problems incorrectly.
My very first objection concerning Fleury’s model1 was that he described the epiblast cells as contained [...]

help a fellow hang himself

A funny side-effect of PZ Myers “An ontogeny of toilet drain behavior” was to bring Fleury’s theory within the range of one of the famous crackpot detectors, Suzan Mazur.

Quite clear

This is an excerpt from Flery’s paper, p16, column 1.

However, Popperl et al.’s article deals mostly with the role of lazarus in the cranial (hindbrain and anterior trunk) compartment, (especially it shows how pbx genes participate in the regulatory loop of hox genes needed to specify rhombomere boundaries in the hindbrain) and when coming to [...]

I was wrong

Well, I was dead wrong in fact, when a few weeks ago I was writing:

What embryology textbooks our physicist have consulted that doesn’t give the origin of the mesoderm and the subdivisions of the mesodermal plate to paraxial, intermediary and lateral? He should give us the name(s) of the book(s) to avoid it(them).

housekeeping

I’m sorry for the delay to complete the 2.2 section presentation. It’s a boring task I promised to carry out and the accumulation of errors induce headaches
I’ll carry it out, but it will take some time.

morphogenic gene

morphogenic gene
How one comes to qualify a gene as morphogenic? Fleury didn’t included this information in his paper, neither in the text or the glossary despite his interest on morphogenesis. I’ve chosen to illustrate the concept using bicoid as it’s one of the examples used by the author.

Mechanosensitivity

Mechanosensitivity
As this is one of the points around which Fleury’s rhetoric articulate I think it will be helpful to have a central post on the subject to link to.
Mechanosensitivity is just another cellular property. Genetically specified as every other one.
Proteic effectors of mechanosensitivity are encoded in the genome and their function is subject to alteration [...]

One of the ex cathedra assertions of Vincent Fleury, in a general public forum where his book and theory where discussed, early 20071, was:
Je suis désolé de devoir insister : ouvrez vos yeux, ça n’a AUCUN sens d’invoquer la fonction d’un organe, si l’ensemble des modifications possibles d’un animal ne sont pas quelconques. L’influence de [...]
