[Taxacom] Croizat "hype"

[Kenneth Kinman]

 Dear All, 
        I wrote the following e-mail yesterday, but decided not to send
it (thought it was perhaps best to let sleeping dogs lie).  But now that
the even more irrelevant subject of Croizat's birth date has been raised
(and prematurely so, for some strange reason), I figure it must be an
extremely slow news day.  So here is something I consider more important
than Croizat's (or anybody else's) 117th birthday a month from now:           
      The work of Hausdorf and Hennig seems to reflect my
own view that vicariance is overly hyped in too many cases. Not that
vicariance is not real nor a valuable concept, but that it is too often
invoked by those who seem to excessively see vicariance where it does
not exist or overly exaggerate its importance. 
       So I repeat again that it can be too much of a good
thing, much like cladistics (especially strict cladism). Although
Croizat also criticized cladistics, that certainly does not offset his
own shortcomings (at least in the opinion of many) in the area of
biogeography. I take both cladistics and panbiogeography with a large
grain of salt, even if both have contributions to make when done so in
moderation. But those who embrace such ideologies without a healthy
skepticism are mostly doomed to eventual disappointment as the
weaknesses of their ideologies become increasingly apparent. Take what
you can from their views, but beware the shortcomings.  Anyway, here's a
link to one of Hausdorf and Hennig's papers:

he could celebrate his birthday wherever and whenever the hell he
wanted... that is true genius...
