* wasn't it a principle of multivariate phenetic morphometrics, back in 
the 1970s, that, given enough characters, all *populations* would be 
diagnosable, and that was the big reason for supporting Wilson & Brown, 
1954, in rejecting the classical (zoological) "diagnosis" subspecies as 
a category?

It's because, in general, every population is different from all others 
that some criterion other than difference (whether morphological or 
genetic), has to be used to define species.
