[Taxacom] New classification of Hominidae (incl. the "hobbit")

Sure - pertinent point. If science is what you believe, then belief is
science. If science is not about what you believe then belief is not
science. I take that view that science is the discovery of what you do
not know (otherwise there would be no point) and in that context there
is no belief in the sense that you cannot hold a belief about what you
do not already know.

 

I'm sure I will fall into some bear traps on that.

Gentlemen,

 

Perhaps the next question to ask in this discussion is one to designed
illuminate the definition of "science" (at the risk of pettifoggery) ;-)

 

Cheers,

	I guess that depends on what we mean by "believe", doesn't it?  

 

Not in my opinion.

 

I

	"believe" that our modern theory of evolution is a powerful
explanatory

	device that is consistent with the evidence and is better than
other

	attempts to explain that evidence (e.g., Intelligent Design). 

 

Sure, I believe that too. But my belief is just my belief. Not science

 

 Of course,

	some use the word "believe" as synonymous with "acceptance of
something

	based on personal or emotional perspectives, rather than
objectively

	determined evidence."  If the latter is what John means, then I
agree -

	it's not science.  But, we must clarify our usage of words when
we make

	absolute statements.

 

My view is different, belief is what you believe based on whatever
influences you. If 'objectively determined evidence' is the basis of
belief then its still belief. Even the 'objectively determined evidence'
is neither here nor there as different people, including scientists, may
believe different things about the same evidence.

 

Just my belief.

	And of course I would agree that Ken should not back down just
because

	someone (in this case myself) disagrees with the informativeness
of his

	classification - just as I would not back down on the orangutan
evidence

	just because just about no one in the primate systematics field
else

	accepts it.

	 

	While my characterization of 'worthless' may be harsh (and no
more harsh

	than the worthlessness of the orangutan theory condemned in the
hominid

	origins field) I at least gave the basis for my
characterization, and I

	stand by the view that a classification that lacks presentation
of the

	systematics decision making process that leads to particular

	classification decisions is not of any real evaluative value. If
others

	think otherwise on this list then I would be interested to hear.

	 

	Ken makes the point that the orangutan theory is accepted by
very few

	biologists is neither here nor there for the science of
classification.

	What people believe is not science.

		Dear All,

		     I was asked to forward the post below to the list.
I thank Mark

		for his response, and my own response to it is that I
indeed do not

		intend to back down.  I gave two perfectly good reasons
for

		preliminarily assigning the "hobbit" (florensis) to
early Homo erectus

		(sensu lato), and near georgicus in particular, and John
Grehan offered

		neither a credible rebuttal to those reasons, nor any
attempt to justify

		any alternate assignment.

		     Nor will I back down on the assignment of
Kenyanthropus platyops to

		Australopithecus (and I suspect it will indeed prove to
be a synonym of

		A. afarensis).  As for the proposed outgroups to
Hominidae, Ardipithecus

		and Orrorin seem excellent candidates, although whether
they clade

		together or separately remains to be seen.
Sahelanthropus is less

		certain and may end up clading with gorillas and/or
chimps.  John

		Grehan's hypothesis of orangutans as an alternate
outgroup to hominids,

		on the other hand, is obviously still accepted by very
few biologists.

		Ken,

		     For some reason the listserve rejected my posting.
Please forward

		it on my behalf.

		Dear Ken,

		I have never posted to this group before and my
expertise is in protists

		(a long way from hominids) BUT I think that science only
progresses by

		individuals putting forward new ideas and offering data
in support of

		them (as opposed to creationist BS of "new ideas").

		 

		Ken, I am way out my area of comfort zone here but I
think for the good

		of science you should not back down, UNLESS the data
compels you to do

		so. I myself have abandoned my long held ideas about
mitochondrial

		origins in the earliest eukaryotes, but it was the data
and reasoned

		arguments that caused me to do so. That is the ESSENCE
of good science.
