This is a nice well written opening post. My only reservations are that it is covering some of the ground already covered in the
'Why are Haeckel's drawings being taught in school?' thread, and that it is likely to have a limited audience consisting of some people interested in evo-devo, who will agree with you, and Randman, who won't.
But all that aside I don't see any reason not to promote this.
On a side note, do you need pharyngeal in there? I shouldn't think anyone who understands what a pharynx is could really object to pharyngeal, it only seems to be 'branchial' and 'gill' which cause the problems as in your cited references. Let me know if you don't see any need to change this, or when you have changed it, and I will promote the topic.
TTFN,
