Harry,

Thanks for the overview. Speaking of the very 
nice paper by Kupriyanova et al. (2006), wherein 
partitioned analyses were performed, I would like 
to mention a paper I just published that 
discusses the fact that this popular approach is 
philosophically untenable: Fitzhugh, 
K.  2006.  The ‘requirement of total evidence’ 
and its role in phylogenetic systematics. Biology 
& Philosophy 21: 309-351. As well, my recent 
Zootaxa paper ('The abduction of phylogenetic 
hypotheses') shows that Bayesian reasoning cannot 
be applied to the inference of phylogenetic hypotheses.

Best,
Kirk
