This is the confusion between evolutionary theory, which is a theory about *mechanisms*, with a particular phylogenetic hypothesis(or concept of the origin of some group(s)). While the latter depends upon the former, the first does *not* depend on the latter, particular phylogenetic concepts can be(and often are) changed without any harm to evolutionary theory. So an argument of this sort has *no* bearing on the validity of evolution. A double flight of fantasy therefor. -- Sarima (Stanley Friesen) {trwrb|allegra|cbosgd|hplabs|ihnp4|aero!uscvax!akgua}!sdcrdcf!psivax!friesen or {ttdica|quad1|bellcore|scgvaxd}!psivax!friesen
