[Taxacom] New molecular propaganda on primate systematics

[John Grehan]

Kim,

I don't have a universal recipe answer. There is none. When there is incongruence it may be because the molecular data are misleading, the morphogenetic data are misleading, or both. My only contention is that there is no objective empirical foundation for the propaganda claim that molecular evidence 'tests' or falsifies morphogenetic evidence.

It is also my contention (which is out of step with virtually everyone else in systematics) that molecular evidence, in the form of sequence analysis, is pretty much phenetics dressed up in cladistic terminology and techniques - and that is basically why molecular evidence can be so misleading (and give rise to morphologically incongruous groupings).

John,

I am not yet sure where your problem is, and so I have a question. How 
do you suggest that we resolve the issue of morphological versus 
molecular data when the data is inconsistent with each other? I have a 
similar issue in Drosophila and in the parrot family.
