Dr. Magnacca, As someone who follows both sets of rules ("Linnean" and PhyloCode), = I=20 could not disagree with you more, except that it IS "more than half."= My=20 guess is, more like 95-99% of the natural history community still use= s the=20 traditional codes. However, I disagree with your categorization of= =20 PhyloCode advocates. Yes, there are "theoreticians" among us, but mos= t of=20 these same "theoreticians" are practicing scientists who produce prim= ary=20 data on a regular basis (or who work with students who do). Of the en= tire=20 PhyloCode community, I can name only ONE person who has ever subscrib= ed to=20 or enacted a policy of "naming every node," and this appears to stem = =66rom=20 his participation in the movement to construct a fully described taxo= nomy=20 under the LINNAEAN rules (thus, as you said, having supersubinfrafami= lies=20 and the like)! As for paleontologists, I know a large number who actu= ally=20 have no problem with the traditional systems. Actually, they very muc= h do,=20 they just don't realize it. However, since paleontology accounts for = 99%+=20 of the history of life, I am at a loss to see why the method of namin= g life=20 should not conform to problems paleontologists face. I have seen the principles of phylogenetic nomenclature applied widel= y (if=20 not deeply) outside vertebrates (see the abstracts for the Paris meet= ing).=20 I have met a large number of non-systmeatists, and non-scientists, wh= o find=20 phylogenetic nomenclature very sensible and easy to understand, and a= =20 beneficial improvement on traditional practice. In my experience, the= real=20 problem is not with non-systematists, it is with natural historians w= ho=20 were indoctrinated under the traditional system. Test how thoroughly = they=20 have thought through the mattter; instead of asking them why we shoul= d=20 group species using phylogeny, ask them "by what means, by what prima= ry=20 observations, by what testable method ARE you sorting your species?" = See if=20 they can answer...
