Here, here!! We have have known since '71 (Ohta and Kimura) that rates of
substitution vary.  We also know the the frequency of the four nucleotides vary
through time.  It is hard to imagine a characterization of the substitution
process that is farther from those assumed by most tree-construction
algorithms.
