[Taxacom] New molecular propaganda on primate systematics

[John Grehan]

I agree in terms of a recipe for deciding. In specific cases one may at least make an argument for one or the other. In the case of hominid origins the congruence of morphogenetics for living and fossil taxa is, for me, quite compelling. For others it is not. But without fossil and living congruence in relationships there is no scientific way to link molecular and fossil (outside those preserving DNA) taxa.

now, that is a very good question! In cases of data conflict where there is no 
obvious way to jump, shouldn't we invoke the old ''incertae sedis"? As Dan 
Bickel once said, 'ah, ''incertae sedis", my favourite group'! Seriously, if 
there is data conflict like that, then we simply cannot know the answer at 
present ... we cannot "resolve" it ...

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.
