What the platypus shows is *de*volution, as far as not having a stomach
goes, and that is in line with ID.
However, I've discovered another possible reason for the atrophied stomach:
the prehistoric ancestor of the platypus was *MUCH, MUCH* bigger, so its
digestive processes were so slow it didn't need a fully functioning stomach.

WTF ??
How is this devolution ......?? there is no such thing anyway .....
evolution is not a one way street ..... it can go in any direction

please explain how this is a) devolution and b) evidence for ID ???

it falsifiable ????
you do realise the Platypus is an EXCELLENT example of evidence for
Evolution ..... it is an egg laying mammal ..... or Monotreme ..... it

Very handy, very handy indeed.

Since there's no such thing a "*de*volution" you've just excused
yourself as a candidate for an intelligent exchange.

Hey, I am on your side! I know Pax's "devolution" was
indistinguishable from "evolution." That is my point. Given his
agreement that the stomachless platypus arose from natural selection,
he agrees with evolution.
Evolution = Natural selection + random variation
Note that I didn't use the usual word, "mutation."
I avoid the word "mutation." I use the phrase "inheritable
variation" instead. Variation is the word Darwin used, and it is
still good today.
I find that some people use rather specific definitions of
mutation that exclude most variations of interest. Some people use the
word "mutation" to refer only to saltation (large changes). I found a
doctor who referred to the word mutation to refer only to small
changes in phenotype. A congenital change is sometimes called a
"mutation." Apparently, the word "mutation" is now used ambiguously.
The word "variation" is more general, but for some reason is less
ambiguous.
When I use the phrase "inheritable variation," they understand
that I am talking about almost any change that can be inherited.
"Variation: can even include epigenetic changes, which may be an
important part of evolution even though they aren't true "mutations."
The word "variation" has historical respectability that Darwin
used it. If anyone wants an example of a variation, I describe a
specific mutation.
I haven't come up with a substitute for the word "random." Many
people have a really poor idea of what the word "random" means.

I suggest you use the word "dimwit" less often on everybody.
However, this was particularly unfair to me.
The Google software sometimes calls me "Lorentz" and sometimes
calls me "Darwin123." I have no idea why both names appear in the same
"Discussion Group." I am not even sure right now which name is going
to appear as a header.
I originally provided different names to different discussion
groups. I wasn't hiding anything. I do not know how to fix it, or
whether I need to fix it.
I am not a sock puppet. Sometimes, people get the idea that
"Lorentz" and "Darwin123" are fighting each other. This is not
intended on my part.
It is interesting that you associated me with a Creationist when
my heading was "Lorentz," yet recognized me as an "evolutionist" under
my "Darwin123" nomer. In fact, H. A. Lorentz did not like Darwin's
theory of evolution. Well, even the greatest minds slip
occasionally.
It is possible that you unconsciously associated me with the
original "H. A. Lorentz." I have a great admiration for both C. Darwin
and H. A. Lorentz. However, my biases have always been with secular
science. I admire the work on physics of H. A. Lorentz, but do not
believe his bias against evolution.
Please understand that Darwin123 and Lorentz are the same. I
have great interest in biological evolution and in physics. The two
subjects are not as far apart, to me, as they appear to other people.
I was not attacking you or any biologist.
However, I have greatly reduced the amount of name calling in my
posts. I suggest you do the same.
This doesn't disprove intelligent design - or at least, one of its variants.
The genes are still there just in case the platypus changes its mind about
having a stomach. If *that* isn't intelligent design, I don't know what is.

Two rebuttals.
1) The genes are broken, and so can't be used to bring back the
playpuses stomach.
2) Genes don't repair themselves when an animal changes its mind.
Since the genes don't serve a purpose, and can't be brought back
by natural processes, then they seem to be an example of "stupid
design."
You may be assuming that the great designer will find it easier
to reconstruct genes that have been broken than by inserting new
genes. In other words, the great designer finds it difficult to insert
new genes from scratch. This implies some interesting limitations on
the great designer. However, speculation of limitations on the part of
the great designer reduces him/her to the level of an extraterrestrial
alien.
I am surprised we don't hear more from the "extraterrestrial alien
ID" crowd. A lot of ID models assume a rather limited intelligent
designer that putters around, makes lots of mistakes, and doesn't
really know what suffering it causes to its creations. "Broken genes"
are consistent with this type of quasi-religious model.
In this type of quasi-religion, the broken genes could actually
have been broken. As in "Oops," broken. I don't believe it. However,
it is logically consistent with the evil we see in the universe.
Some of the pagan Gods fit with this type of model. I would love
to see what would happen if a pagan follower were to teach his
religion in a public classroom in Kansas. Imagine a class of Wicca in
a public school in Kansas. I think the result would would be to the
Scopes Monkey trial as King Kong is to monkeys.
However, I don't think Pax would be comfortable with this type
of God. His ID theory implies a God who does not make mistakes, who is
working in the long range interests of his creations. Most "ID"
practitioners really have a loving, personal God in mind. They may
have more luck if they promote UFO Alien Worship.
I suspect a lot of noncoding genes serve as "spacers" on the
chromosome to allow other genes to experess themselves at the right
time. If that is so, then the function of these "nonworking genes"
should have nothing to do with the "stomach" genes of other animals.
I'm going with your last clause: you don't know what is.
Budikka
If you see evolution as going in the direction of more complexity, you could
call the opposite devolution, I suppose.

The platypus seems more something between avians and mammals to me.
It's duck bill doesn't look very reptilian.
I know there were some saurians who had some kind of duck bills, but they
have all been extinct for tens of millions of years, while the platypus is
living right now. It has even acquired hair, which isn't that different from
bird's feathers, but no reptile ever had anything like it.
Monicker
Darwin123, are you sure those stomach genes can't be used at all ?
When I wrote "changes its mind" I didn't mean that literally, of course.
Only someone with superficial, literal understanding could have understood
it this way. In practice, that would mean "when evolution demands it". And
if really those genes are just a remains of once working genes without any
other value, that's not 'stupid design' either. Evolution should get rid of
them in due course.
There's much more you wrote in your reply which could be debated, but maybe
that's more stuff for some other ng.
Monicker
Budikka
Do you ?
Monicker
In one sense, evolution IS a one-way street. Once you evolve, you can
not go back to the thing from which you evolved.

There's no such thing as devolution. It's a make-believe thing.

There isn't one.

Well, no, the platypus is not the transition between mammals and
reptiles. It possesses some ancestral traits, but the transitional
species between reptiles and mammals all lived at least 250 million
years ago.

Yeah he shot from the hip on that one. It was pretty obvious you were
disagreeing with Pax.

The bill of the platypus is nothing like that of a bird.
A bird's bill is made of keratin.
The bill of the platypus is bone covered in skin.
That a big difference.

You really think hair isn't that much different to feathers?
Perhaps you should take a look at the structure of both, and how they
grow.
Again there is a big difference between the two.

The only time I've seen it used is in the context of governance where
the central government gives power to a state, province, city, county or
other subsidiary government. In discussion of biology, it's evidence
that the person using the word is either ignorant of what evolution is
or intentionally misleading folks in the discussion.
