[Taxacom] New paper: Ruggiero et al. "A Higher Level Classification of All Living Organisms"

[Richard Pyle]

We all like to believe our own definition of “science” is the correct one.

 

Sigh….

At least the quotes show that the authors admit their work not be science (if science is understood to be about the nature of reality beyond 'consensus' opinion).

Hmmm....  I've been deliberately quiet on this thread as well.  I appreciate the viewpoints of Ken and others in terms of holophyly, the value of acknowledging paraphyletic taxa through Linnean nomenclature, etc.  This is all good philosophical grit, and I enjoy the intellectual stimulation as much as anyone.

However, this thread began (and remains?) relevant to the PLoS ONE publication of Ruggiero et al., which provides a generalized **CONSENSUS CLASSIFICATION**.  Perhaps there is some misunderstanding on what is meant by this term (and the associated classification)?  Anyone who read as far as the abstract of this paper should at least know that:

"This classification is neither phylogenetic nor evolutionary but instead represents a consensus view that accommodates taxonomic choices and practical compromises among diverse expert opinions, public usages, and conflicting evidence about the boundaries between taxa and the ranks of major taxa, including kingdoms."

And:

"Beyond its immediate use as a management tool for the CoL and ITIS (Integrated Taxonomic Information System), it is immediately valuable as a reference for taxonomic and biodiversity research, as a tool for societal communication, and as a classificatory “backbone” for biodiversity databases, museum collections, libraries, and textbooks."

In this context, it is ABSOLUTELY CORRECT that the subtaxa within a taxon are alphabetically arranged!  It is absolutely NOT intended to reflect any sort of "naturalness" in patterns of evolution.  Yes, it probably does kinda- sorta- happen to reflect modern views of evolutionary relationships (otherwise there wouldn't be much consensus behind it).  But its function is to serve as a tool for informatics and generalized (i.e., highly simplified) organizational representation of life on Earth.  As such, it is overwhelmingly valuable to the people for whom it was intended (see second quote above).

Aloha,
Rich
