[Taxacom] New lizard species

truth by consensus, eh? Millions of people in the world believe in a Christian God, does this make it so?

>The key word, in my opinion, is not "character" or "attribute", it's "organism".  The phrase "attribute of organisms" means that the attribute is a property of the *organisms*, not of the *population* of organisms.

again, you are reading into the Code what isn't there! "Attributes of organisms" may be either intrinsic or extrinsic, and nothing in the Code restricts Article 13.1.1 to the former.

the ICZN has no mandate whatsoever to place any restrictions on what is or is not an allowable taxonomic character or taxonomic methodology, it can only regulate NAMES for taxa, by prescribing FORMATS (not CONTENT) that taxonomists must follow

if you don't understand that, then you should not, IMHO, be a commissioner ...

Sorry -- the formatting got botched on the last post.  Here again:

Once again, Thomas Pape provided the answer to an unnecessarily long and contentious thread.  Once again, nobody seems to have noticed.  I'll re-post what Thomas said:

The key word, in my opinion, is not "character" or "attribute", it's "organism".  The phrase "attribute of organisms" means that the attribute is a property of the *organisms*, not of the *population* of organisms.

The reason the diagnosis fails Art. 13.1.1 is because the attribute "cluster" applies to a population of organisms, not to organisms themselves (as in, "...*populations* that cluster with those ..." [emphasis added]).

Is this open to interpretation?  Yes.  But so is virtually every other sentence in the ICZN Code, as well as the botanical Code, as well as just about any other document in any language.  In the legal field, it falls upon judges who are very familiar with legal Code, and the language the Code is written in, and the contexts in which it was written, to disambiguate alternative interpretations of meaning in words and phrases that appear in the legal Code.  

In the case of ICZN, the Commissioners serve in this capacity -- it falls upon them to determine the appropriate interpretation of potentially ambiguous language in the Code.

By my count, four active ICZN Commissioners, and one former ICZN Commissioner (including two former presidents of ICZN) have all weighed in on this thread.  They have been unanimous in their assesment that the diagnosis, at least as presented to Taxacom, fails to comply with Article 13.1.1 of the ICZN Code.

Aloha,
