Re: Origin - the wrong word?

From: "Tom Hendricks" <tomhendricks...@xxxxxx>
You don't have an ocean without a sun heat cycle. Now you're
being silly for debate. How can you have liquid water without
a sun cycle - If no cycle then you have two options
a its always getting hotter -all water would burn up.
b. its always getting colder, all water would ice down.

You seem to have no comprehension of either blackbody radiation or
equilibrium. Any object emits EM radiation at a rate porportional
to the fourth power of its temperature. Any object receiving EM
radiation at a fixed rate approaches an equilibrium temperature
where the amount of EM radiation give off equals the amount of
incoming radiation. It neither gets hotter and hotter without
limit, nor gets colder and colder without limit.

No *cycle* whatsoever is needed to maintain that equilibrium.

A Spiegelman-like monster would win out.
No. The Spiegelman monster is a parasite upon already-existing
life, not a self replicator.
A Spiegelman-LIKE monster - definition: it replicates faster,
it'll use up the other base pairs faster and win out.

In order to replicate at all using the PCR method you proposed,
without an artifical supply of ATP-activated nucleic-acid bases and
also primers and also replicase enzyme, the RNA or DNA sequence
would need to somehow catalyze the synthesis of all those missing
ingredients. Anything like the Spiegelman monster can't do that.
Anything that *can* do all that would be much larger than the
Spiegelman monster. The whole point of the Spiegelman monster is
that with all those extra ingredients artificially supplied,
there's selection pressure to dispense with sythesizing the
ingredients, yielding a very short sequence instead of anything
that could fully orchestrate its own replication.

Now if you instead suggest a totally different method, nothing like
the PCR method at all, nothing using primers or replicase enzyme or
ATP-activated bases, there's no experimental evidence any such
scheme would work. The existance of the PCR method is irrelevant to
your annealing-sans-enzyme scenerio, so I have no idea why you
would mention PCR except to confuse the discussion. Do you know of
any experimental evidence that under certain specific abiotic
conditions a heat cycle all by itself will make nucleic-acid bases
appear spontaneously and form random polymeric strands spontaeously
but preferentially form complementary strands to those already
present so that replication and hence heredity would predominate
over production of a random mix of sequences that fail to undergo
any significant replication?

By the way, why did you start this thread about the origin of life
in sci.bio.evolution instead of in talk.origins??
