  That the variations between organisms is a result of
sampling end products that have undergone a
step-by-step transformation/aquizition of genetic
variance that expresses as morphology or not, and that
each change is considered enough to create a box
within another box (to use Gould's analogy).

  Perhaps it is so frightening a concept to completely
abandon taxonomy based on the incomplete sampling of
the geological record and the simple fact that either
a branching tree with end products (successive
diversity) or nested ingrowth of lines to a common
trunk (interbreeding) may be both correct, and _no_
taxonomic hypothesis has so far found a way to
successfully distinguish and define these qualities
together. We would have to abandon our Dinosauria,
Mammalia, Aves, Bryozoa, Archaea, Echinodermata,
Arachnida, etc.; all that ... lost ... because either
competing hypothesis, nesting or branching, cannot
correctly show the distinction between genetic change
and mutation. Or how bacteria can literally pass genes
from one member of a generation to another, or
cross-generational, without fissioning (Lateral Gene
Transfer).

  What a frightening concept, but something has to be
realized that allows parent-child relationships to be
classified in the same manner as sibling-sibling
relationsips, or that allows two different
classificatory hypotheses to operate in the same system.

  Dinosaurs are horrible, terrible creatures! Even the
  fluffy ones, the snuggle-up-at-night-with ones. You think
  they're fun and sweet, but watch out for that stray tail
  spike! Down, gaston, down, boy! No, not on top of Momma!
