vincent fleury: By the way “I can has L2/R2″ is not a sentence Aha! this is not a sentence. I was waiting for this one since I read the paper. For Dr Fleury first step here, and second one here, both necessary to get the flavor. For everybody else, a puzzle served below [p22 col2 [...]

[p 20, col 2, §3] Genetic analysis, in relation to evolutionary issues, shows that actually, genes for limbs and for tails are similar, and many are identical ([98] and references above31, Ref. [60]). Also, genes which serve to form the true limb skeleton, are actually present in fish fins, in which such skeletal elements are [...]

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.

Now, that’s a clarification!

At least! 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 you now know it, better than anyone else. Well, no, [...]

Nevertheless, when folds growth is prolonged by evolution, it is so in the direction of the existing fold. Stated otherwise, if the appearance of a fold corresponds to crossing of a generic biomechanical threshold for folding, one may expect that the fold is itself stable in an open set of parameters, such that, “conserving the [...]

[p21, col 1, §2 Hindlimbs form first during development of most tetrapods, and they are likely to be last to disappear, as known in snakes. The fact that hindlimbs form first and are thus often larger, may be ascribed to the narrow spacing in the caudal part of the early embryo (more below). Ahem, hindlimbs [...]

Posted by: Jerry Coyne | June 17, 2009 3:40 PM Man, I’m glad YOU did this rather than I. We keep hearing that this kind of idea presages a revolution in evolutionary biology, in which natural selection will be relegated to a minor role. That revolution, however, always seems to be just a wee bit [...]
