[Annelida] Alert - Annelid molecular phylogeny

[J. Kirk Fitzhugh]

Geoff,

The more serious problem, beyond a moleculoid tree not meeting 
expectations (and expectations are irrational anyway), is that all 
relevant evidence is not considered, which makes these standalone 
sequencing forays in vain.  This has nothing at all to do with 
outgroups, and cannot be explained away.  One would think that the 
editors of Cladistics would be the first to see this.  I can suggest 
my recent papers on the topic of total evidence:

Fitzhugh, K.  2006.  The abduction of phylogenetic 
hypotheses.  Zootaxa, 1145: 1-110

Fitzhugh, K.  2006.  The 'requirement of total evidence' and its role 
in phylogenetic systematics.  Biology & Philosophy 21: 309-351.
