Dear colleagues,
I support the compromize of delaying discussion of Kevins's (Padian)
proposal to forbid apomorphy-based definitions till after we have
settled the issue of the species proposal. But I disagree slightly with
Kevin's (de Queiroz) statement that not much has changed since the Paris
meeting. We have had 8 years to think about these issues, and the CPN's
composition and even number of members has changed. I think that it is
really up to the whold CPN committee's to decide if we discuss this or
not, but I think that usually, by default, we agree to discuss, although
we may or may not approve the amendment. And I don't want to disucss a
long discussion on this topic now, since most of us seem to agree to
postpone it, but I would be favorable to at least advising against
apomorphy-based definitions, as I had emphasized at the Paris meeting.
Best wishes,
Michel
