If you want to break a phylogeny into lineage segments, then "species" do not exist, as far as I can tell. They become like any other clade, divisible only by morphology, or by genetic isolation, or whatever one chooses to separate them. Then chronospecies can be defined at any point a similar condition prior to a recognized "species" would have occured. For every character, this means for dinosaurs alone, there are over 6 times as many species recognized today. More for birds (thousands upon thousands of new "species"). An alternate method would be to settle on a morphological basis, or an exclusive-genetics basis, and deal with the consequences of "defining" species formally for the Code. Or, you can give the describer the means by which to treat his species by the provided criteria for each species. "If definition A, then do a, then b, then follow with c...." and etc. Cheers, ===== Jaime A. Headden Little steps are often the hardest to take. We are too used to making leaps in the face of adversity, that a simple skip is so hard to do. We should all learn to walk soft, walk small, see the world around us rather than zoom by it.
