Right to Reply – kind of

I got a request for a « right to reply » in the comments of the origin of loss of credibility. Guess who send the request: Vincent Fleury, not Stuart Pivar. Not much of a reply to the question I was asking:

Now, maybe Vincent Fleury have something to say to the editors of this journal. The vortices aren’t apparent there 😀

In other words: will he write to Simon Mitton, Astobiology’s (sorry for the confusion, there is a journal named just Astrobiology, my terming was confusing) the Journal of Astrobiology editor, to contest Pivar’s paper? After all, Fleury is known to write e-mails or posting letters. It seems that I’m not the only one to expect a confrontation of these two guys’ theories (I would prefer something more civilized 😉 ). Or a collaboration to build some new unified theory. (that’s terrifying)

Instead, Fleury offered a link, to the announcement of one of his seminars, planned for tomorrow, september 30 at 11 AM at the library of the Hydrodynamics Laboratory, titled « Physics of embryogenesis and evolution » (Physique de l’embryogenèse et évolution). Hopefully (for Fleury, unfortunately in general) no embryologist or evo-devo around to discuss the matter.
But, more importantly, that doesn’t answer my question, does it? That doesn’t answer either previously asked questions that are hanging out there relative to his theory and some of his assertions.

If Fleury thinks that by advertising his lecture he is adding some credit to his theory he is wrong. As much credit as it had, probably, with the invited review in EPJ AS. But maybe the content will be informative: it was in one of his presentations that he admitted not having the data which would support this assertion.

Maybe there will be a Q&A session after the speech. In this case, people attending may be interested to seek clarifications about a few points contributing to support Fleury’s theory. I will suggest:

Certainly clarifications about:

Vekris : the antero-posterior construction of animals is bullshit, the induction of limbs by genes is bullshit, the colinearity of hox genes is bullshit, the selection of tetrapods by evolution is bullshit, the duplication of genes between hindlimbs and forelimbs is bullshit

and

The pattern of tetrapods exist in the platonician space of forms, just like the sphere. You can write its essence without evolutionnary arguments

should also be asked.

If you can do attend and ask questions, the comments will welcome any direct and on focus answers.

Looking forward for the seminar’s video, if any.

the origin of loss of credibility

What degree of credibility do you attribute to a journal (International Journal of Astrobiology) publishing and highlighting Stuart Pivar’s « The origin of the vertebrate skeleton« .

Capture d’écran 2010-09-28 à 11.30.14.png

The lowest possible. Congratulations to Simon Mitton (Managing Editor, astronomer [physics and astrophysics]), Rocco Mancinelli [biologist] and Frances Westall [biologist] (Associate Editors).


And PZ Myers on the subject

Robert Lanza: Streisand effect engaged

What Happens When You Die? Evidence Suggests Time Simply Reboots, by Robert Lanza, M.D., Scientist, Theoretician, triggered more reactions than other posts of Robert Lanza, such as « Is There a God or Is There Nothingness? New Scientific Paradigm » or « Why You’re Alive and Can Never Die: The Larger Scientific Picture ». Or Robert Lanza‘s « Biocentrism: How Life and Consciousness Are the Keys to Understanding the True Nature of the Universe » book, where Robert Lanza lays out his theory of everything.

I wonder why?

Anyway, Lanza is not happy with it and he wrote to demand to take down posts critic to his stance, addressing Seed Media. That’s a stupid thing to do, as much stupid as writing letters to vice chancellors of academic affairs to ask them to interfere with free speech of one of their colleagues.


This post is part of a Google bomb, illustrating the Streisand effect: When trying to block information backfires.

I wonder if I shouldn’t have a « quantum flapdoodle » category/page to list the various instantiations of… quantum flapdoodle.

Avatar, suite

Jean-Baptiste André et Nicolas Baumard, signent un très agréable Point de vue, dans le Monde, que Fabrice G vient de me signaler (remerciements publics).

Je retiens leur dernier paragraphe :

C’est justement toute la puissance de la théorie néo-synthétique de l’évolution (la théorie vraiment « standard » cette fois) que de pouvoir expliquer l’ordre, la téléonomie disait Monod, sans supposer un ordre initial. C’est parce que la sélection naturelle a agi sur le monde qu’existent aujourd’hui sur Terre des structures aussi organisées, aussi improbables a priori, que les structures vivantes. Pour reprendre la métaphore de Dawkins, l’horloger est aveugle mais son travail ressemble à celui d’un voyant. L’évolution n’a pas de vision, elle ne planifie pas. Mais, par le jeu des mutations et de la sélection, elle produit de l’organisation. Ne retenir que la cécité de l’Horloger, et donc que le hasard, c’est oublier la moitié de l’histoire, la meilleure. Prétendre que le darwinisme est incapable de rendre compte des relations d’ordre qui lient les structures vivantes entre elles, c’est tout simplement n’y rien comprendre du tout. Si les espèces indépendantes se ressemblent, ce n’est pas parce qu’il existe un plan divin, ou un ordre cosmique, c’est tout simplement parce que tous les êtres vivants, produits de la sélection naturelle, sont soumis aux mêmes contraintes. Non, les théories anti-darwiniennes défendues par Jean Staune, Vincent Fleury, et les membres de l’Université Interdisciplinaire de Paris, ne sont pas, pas un seul instant, renforcées par la ressemblance entre espèces indépendantes, pas plus sur Pandora que sur Terre.

et je leur dois un coup à boire 😉 [liens par moi]

Maintenant, va falloir que je trouve le texte de Thomas Heams à lire; des abonnés au Monde qui pourraient me le sortir SVP ? Merci Elsa !

Le non-darwinisme visionnaire de James Cameron, par Jean Staune – commentaire

Heh ! Simon Conway-Morris, faisant sa promotion du soft-créationnisme à la John Templeton Foundation, suggère que son téléologisme théiste est justifié par la convergence évolutionnaire et Jean Staune est toutes choses. Le TNBI est plein des non-sens de Jean, voilà qu’il en bave jusqu’au Monde !
