> Everything from the genus on up is imaginary, a figment.
I'm sure Creationists will find that a great quote. I will also make
sure to store that one. In panbiogeography, somehow these 'figments'
(genera, families etc) all work themselves out spatially in a very
precise way, so precise that definitive geological correlations are
possible and predictions may be made that advance evolutionary knowledge
beyond the immediately empirical.
Panbiogeography has worked very well without sweating over what is or is
not a true species, or worrying about whether a 'subspecies' or 'genus'
etc. has any lesser reality than the species, or anything else for that
matter.

Hi Robin,
You wrote: 'Michael Heads says the panbiogeographic species concept is
"not
special." How does one criticize a species concept with such a
characterization? Is it a valid species concept? Can we ever get an
example?'
MH: I mentioned the paper by Mallet (2010 Biol. Philos.) that dicusses
these
issues. Another good one is: Mallet, 2008, Phil. Trans. Roy. Soc. Both
the
papers are freely available on the net. I'm not sure what you mean by
'can
we ever get an example'.
RZ: 'He also says the species in diffeent groups is different. Like how?
Do
panbiogeographers recognize the usual list of different species concepts
and
pick one or the other as appropriate? Or is it something implied and
unstated that cannot be discussed?'
MH: As you wrote in your last mail: 'different species concepts can be
most
effectively used for different groups'. The species concept may be
different
even in related genera, depending on who revised or sequenced them.
Everyone
knows groups in which the species (or genus, or family) concepts are
very
narrow, while broad species are accepted in other groups. That's fine -
there is no need to have a single, overarching 'species concept' and we
are
suggesting that the search for one is pointless.
RZ: The reason no one can pin down our panbiogeographers is that their
concepts are thin. They can never be strongly confirmed if they are
tergiversated and morphed with every challenge.
MH: Which of our concepts has changed following a challenge? We've been
arguing that species are not special for decades - that's why it's so
satisfying to read Mallet's papers.

I really think all taxacomers might profit from reading Believing
Bullsh.t
by Stephen Law. He list 8 ways people immunize their beliefs from
contrary
arguments. In addition to cautioning and auditing ourselves for our own
nonsense, I think certain elements characterize how our favorite
panbiogeographers immunize their methods of study from our criticism.
Note here that Michael Heads says the panbiogeographic species concept
is
"not special." How does one criticize a species concept with such a
characterization? Is it a valid species concept? Can we ever get an
example?
He also says the species in diffeent groups is different. Like how? Do

The reason no one can pin down our panbiogeographers is that their
concepts
are thin. They can never be strongly confirmed if they are tergiversated
and
morphed with every challenge.
Law also cites a Nuclear Option: when backed into a corner, one can also
damn reason itself. That is, if everyone looks to some standard, then
for
every -ism, that's our own trip. Hence we hear the foibles of
Darwinists,
cladists, and modern synthesists such that all systems of inquiry are so
fraught with problems that who are we to criticize anyone else.
I think exchanges on Taxacom are phenomenally instructive because of the
diversity of foibles in thought we all exhibit, and particularly their
serious critical discussion by others. The panbiogeographers are
disengaged
from this process, and the means are clearly discussed in Law's book.
This is not to say that Law does not indulge in his own bullsh.t. His
attacks on theism fails again and again because he attaches handles
(e.g.
total good) to the god concept then attacks the handles, then says if
there
are no handles, what good is the god concept? He is also the typical
philosopher who relies on reason totally, bows to science but is
generally
ignorant of science. For instance he says science cannot explain the
creation of the universe. Nonsense. A physicist named Tryon figured out
that
the positive net mass energy of matter equals the negative gravitational
potential of matter. They cancel out and the universe what thus created
by
quantum fluctuation involving pair generation in a vacuum. Voila, the
creation of the universe (for more see a book by Barry Parker called
Creation, cheap used at Amazon.com.

Hi Richard,
You wrote that 'a species is still defined most generally as the basic
unit
of taxonomy'. This is true in the Mayrian, antidarwinian synthesis. In
Darwin and in panbiogeography the species is not special and the basic
unit
is the character or, at the taxonomic level, the taxon (whatever its
rank).
You also wrote: 'Suggesting that one should follow one or the other
[biological species concept or darwinian/panbiogeographic species
concept]
is not helpful since (1) different species concepts can be most
effectively
used for different groups (paraconsistency)...'. Exactly: this is the
panbiogeographic species concept - the 'species' in different groups are
not
necessarily equivalent in their branch length or degree of reproductive
isolation.

Well, sure, usage matters, but a species is still defined most generally
as
the basic unit of taxonomy. This extra baggage refers to either
process-based theories, e.g. biological species concept, or the
panbiogeography concept which is vaguely defined as some step in a
ranking.
Suggesting that one should follow one or the other is not helpful since
(1)
different species concepts can be most effectively used for different
groups
(paraconsistency), (2) sometimes just "basic unit of taxonomy" is good
enough for a helpful contribution to science.
"Real"? What is real? Genera are not real? There are theoretic
explanations
that describe their evolving, so evolution is not a criterion. I think
there
is a lot of rejection of theoretic realities going on nowadays, and I
don't
mean alternate realities.

Hi Curtis,
Panbiogeography has developed many new or unusual concepts for old ideas
and
terms, e.g. evolution, origin, species, dispersal, ancestor etc. These
new
concepts are clarified in the panbiogeographic literature, and may often
be
confusing if you haven't read it. For example, the concept 'species', as
used by many biologists, is the 'absolute' concept of Mayr - species are
real, subgenera and subspecies are not. 'The species' is the basis of
evolutionary theory, biodiversity assesment and so on. Panbiogeography
instead used the Darwinian, relativistic concept - a species is not
special,
and is just the unit between subspecies and subgenera. Geneticists who
work
on speciation are now starting to use this and to question why Mayr etc.
were so antidarwinian (see the outstanding article: Mallet, J. 2010. Why
was
Darwin's view of species rejected by twentieth century biologists? Biol.
Philos. 25: 497).

How did Robin mean it? How did John mean "null hypothesis"?
Panbiogeography can only seem esoteric, and subject to marginalization,
if it uses technical terms commonly used by other biologists, but with
different meanings, and without the differences being clarified. It's
easy for the rest of us to assume "track", for example, to be a
specialized term in panbiogeography, since it has a multiplicity of
meanings in standard English, but most of us with a biometrics
background would assume we know what "degrees of freedom" and "null
hypothesis" mean, and would only be puzzled, and I admit put off, by
what would seem to be redefinitions.
