Yes, you did miss something, i.e. the point! My point was that classification (particularly when based on phylogenetic analyses) is continuously changing with new information coming in all the time. Yet, I strongly suspect that it may be something like at least a decade before CoL, etc. think about reviewing the results of Ruggiero et al. (2015).

Hi
all,
A couple of
observations:
First,
as Richard Pyle noted, consensus does not necessarily mean
unanimity. If so, then most political bills would never be
passed. Think of 'consensus trees"; these reflect
areas of agreement among competing views and leave the
differences largely unresolved.
Second, perhaps I missed something
in Stephen's last note; isn't any classification
(except for those that are purely fanciful) limited by what
is presently known?
Third, I haven't read the paper,
but comments made by several participants certainly come
close to reflecting the thinking of numerical taxonomists,
whose classifications were based on overall patterns of
agreement among all characters available (or all characters
used in the particular analysis). These classifications
were intended, in keeping with ideas expressed by Gilmour,
to be useful and, perhaps, serve as the basis for inferring
components of evolutionary relationships (although this was
not the goal). Based on what I've read here, the new
classification attempts to provide a useful
consensus.
Cheers,
Dick J

I have no
problem with alphabetical sequencing of taxa at each level,
in fact I prefer it. My only gripe is that the paper be seen
for what it really is, i.e. simply a choice of
classification, based in part on PRESENTLY available
evidence. Also, classifications should really be specified
from the bottom up. Top down approaches just push a lot of
unresolved rubbish down to the lower levels and ignore
it.

Sure, one could argue
indefinitely about how to contruct a "better"
consensus classification. But these LITERALLY
endless arguments are exactly
why no such
comprehensive classification has previously been
presented
FOR
THE PURPOSES INTENDED BY THIS
classification. The value of this listing is
not the "classification" part, so
much as it is the "consensus" part.
Consensus is not the same thing as unanimity.
You can certainly convey your
personal
opinions (as listed below) to the architects of the
list,
and maybe
a future version will be altered
to reflect them (assuming your opinions
resonate with the broader consensus).
In any case, sequencing of names in a list is
an incredibly BAD way to
represent
phylogenetic information; ESPECIALLY in the context of
that
this
particular list is intended for. If
you want to represent affinities of
taxa,
there are three basic ways to do it:
1) Come up with a mark-up scheme (like
yours)
2)
Acknowledge names at ever finer units of intermediate
ranks,
so that
relationships can be represented
within nested sets
3)
Draw a cladogram
For the purposes of this list,
any sequence other than alphabetical
(particularly if some sort of information is
intended to be conveyed by the
particular
sequence) would have been a very silly thing to do.
Aloha,
Rich

Hi Rich,
I think John is
being overly harsh. Overall, it's not a bad
classification, but I think it certainly could
be made better. The protist
classification
is very good, thanks to the work of Thomas
Cavalier-Smith.
It's too bad he
couldn't get his co-authors to classify
Posibacteria
and
Archaebacteria together in one Kingdom
(and Negibacteria in another). I
still
think alphabetizing the lists is still a sad loss of
information. It
may be a bit more
convenient for some, but I'm sure many others will
find
the loss of information more than just
an inconvenience.
I don't understand why they
didn't subdivide the list of orders of
eutherian mammals (and splitting Pilosa and
Cingulata as separate orders
unfortunately
eliminated the more familiar name Xenarthra, as well as
being
separated alphabetically). And of
course, I would raise Aves back to Class
status, and add an {{Aves}} marker within
Reptilia. Anyway, even if they
insist on
retaining the alphabetical "convention" for
the
convenience of
some, there is still plenty
of room for improvement in my opinion.
---------------Ken
P.S. Hexapoda is probably
polyphyletic. Collembola almost certainly
evolved hexapody independently from one group
of crustaceans, and the
insects from a
different group of crustaceans
.

so-called ecological areas were
defined in
New Zealand (Under the Protected Natural Areas program,
and
with
lots of money to boot) according to
compromises over different opinions
about
where the boundaries between the areas were to be drawn
(said
boundaries having no reality anyway,
hence the ability to 'compromise').

very broad range of activities, such as
phylogenetics, taxonomy,
nomenclature,
informatics, and a whole host of other things that may

That seemed awfully presumptuous

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:

classification is neither phylogenetic nor evolutionary

practical
compromises among diverse expert opinions, public
usages,

conflicting evidence about the

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).
