Arghh! I can no longer say my analysis uses more characters than any
published study ;-). I have a measly 296 entered and 50 or so still being
studied. >>
Is it just me, or do other people find this endless hunt for ever more
"characters" just plain CRAZY? The computer will, of course, grind out trees
as long as you give it "characters" to chew on, but do you really BELIEVE in
the resulting phylogenies, or are they just so much nonsense, to be discarded
when the next batch of computer-generated trees, crunching even more
"characters," emerges? If so, why not hold out until you've found ALL
possible "characters," grind out the one big tree and be done with it? But
then how would you CHECK this tree against reality? Are synapomorphy wars
what the search for truth in paleontology is really like?
