Snakes follow lizards, in evolution [48,99]. However, many snakes still have vestigial limbs (boa, python [49]).
Reference 491 is incorrectly cite here; could be reference 48b2 instead.
It’s a pity that Fleury don’t present Cohn & Tickle’s [48b] and Cohn et al. [48a]3 in his discussion of limb positioning and specification.
1. Tbx3 can alter limb position [...]

The invertebrate morphogenesis
The second section of Fleury’s paper is about The invertebrate morphogenesis and the example chosen is Drosophila the fly, which is the most studied of the invertebrates but far from describing the “invertabrates” morphogenesis in general, just take a look at a sponge. Two subsections, The fly bauplan and The homeobox genes.

Abstract
The origin of tetrapods is a complex question that webs together genetic, paleontological, developmental and physical facts.
A very interesting question of evolutionary biology indeed, mobilizing the efforts of many.
Basically, the development of embryos is described by a complex mix of mechanical movements and biochemical inductions of genetic origin.
It is difficult to sort out in this [...]

It seems that the European Physical Journal – Applied Physics inaugurates a new field of papers dealing with applied physics on biological subjects. The inaugural paper by Vincent Fleury deals with tetrapod’s embryogenesis.
As the author and the author’s views on biological evolution and Darwinism have been of interest for me the last two years, I’ll [...]
