Where's the beef?
Kuresu:
And evolution itself is a fact--we witness species changing over time.
That is subjection...
Natural selection is a fact that we can witness and test emperically. But organisms adapting to their environment is not equal to evolution.
What we witness factually, is better explained by organisms adapting to a devolving environment, and in the process... losing genetic diversity.
Perhaps you call death and extinction, evolution. I suppose that is debatable. I think it is clear to all that the concept of evolution was and is intended to explain the increase in order.
And what is particularly telling, is the problem of origin, in that, evolution (as an assumed universal trait; cosmologically or biologically) does not show itself in any form that is emperical.
For more explanation, here is a link to your topic on abiogenesis: http://EvC Forum: The "Digital Code" of DNA -->EvC Forum: The "Digital Code" of DNA

Re: Where's the beef?
Percy:
How should these contradictory statements be resolved? Are you trying to say that evolution is only possible in a devolving environment, whatever that is?
One at a time... I look forward to addressing your questions after settling some other business elsewhere. No contradiction, just a poorly constructed sentance...

Re: Where's the beef?
Percy:
So you're saying that we *have* made empirical observations of evolution, albeit in a devolving environment.
It is called 'Natural Selection'. If we can agree to that, then unquestionably... I have three children and they are not clones.
Rob:
And what is particularly telling, is the problem of origin, in that, evolution (as an assumed universal trait; cosmologically or biologically) does not show itself in any form that is emperical.
Percy:
And now you're saying that we've never made empirical observations of evolution, including biologically.
No, I am referring specifically to the problem of origin, in that it is assumed even by the work going on in the RNA world that life did not sponaneously arrive as 'whole' even on the level of single celled organisms, but occured through some as yet unknown self replicating mechanism which consists of an unspecified series of changes (ie evolution).
This discussion... has, in a sense, focused on a straw man; the myth of a self-replicating RNA molecule that arose de novo from a soup of random polynucleotides. Not only is such a notion unrealistic in light of our current understanding of prebiotic chemistry, but it should strain the credulity of even an optimist's view of RNA's catalytic potential...Without evolution it appears unlikely that a self replicating ribozyme could arise, but without some form of self-replication there is no way to conduct an evolutionary search for the first, primitive self-replicating ribozyme.
(source / Darwin's Black Box / Joyce, G.F., and Orgel, L.E. (1993) "Prospects for Understanding the origin of the RNA World" in The RNA world, ed. R.F. Gesteland and J.F. Atkins, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, p. 13.)
So yes, we have emperical evidence of the one, but not the other. It is simply assumed to be a universal trait- since it happens here, it must have happened there.
As Jonathan Wells said, "Natural selection can explain the survival of the fittest, but it cannot explain the arrival of the fittest."
What you guys are saying is that because we can see all of this emperically verified evidence of apdaptation here, we are then able to see (though not emperically) what actually is over there. And even though it is not proven, we can proceed with robust confidence.
Do you concur?

Re: Where's the beef?
Percy:
From your side of fence and returning to the actual topic, what do you see as the most convincing evidence for evolutionary theory?
That is a flawed question.
In my opinion, the most convincing evidence for the theory of evolution, is the supression of truth by men with conflicts of interest.
Since there is no emperical (testable scientific) evidence other than circumstantial in nature for the fact of evolution, I was forced to look to the actual cause for it's 'theo'retical invention.
As Dr. Henry Morris put it...
UNKNOWN CHEMICALS in the primordial past...through...
UNKNOWN PROCESSES which no longer exist...produced...
UNKNOWN LIFE FORMS which are not to be found...but could, through
UNKNOWN REPRODUCTION METHODS spawn new life...in an...
UNKNOWN ATMOSPHERIC COMPOSITION...in an...
UNKNOWN OCEANIC SOUP COMPLEX...at an...
UNKNOWN TIME and PLACE.
I've never been in such a strange church as EVC where people eagerly encourage each other that their lifestyles are moral. They invent all kinds of stories to celebrate each other. Perhaps one needs to go to a University to find something equivilant.
Phillip Johnson - author ”Darwin on trial’ / Professor of law (emeritus) University of California at Berkeley-
Johnson on the question: ”What is Evolution?’
“With Darwinian evolution, we’re dealing with something that is much more than a scientific theory; it’s a creation story. In fact, it’s the creation myth of our culture. Every culture has a creation myth, which tells the people where they came from, what is ultimately ”real’, and how they relate to that, and where they should get their knowledge- their information from.
Every culture has a priesthood that has custody of this creation story and that gives that knowledge. In our culture, the priesthood is not the clergy or the ministers in church, it’s the intellectual class, and especially the scientists.
So the Darwinian story says that ultimately all that is ”real’ is nature. Nature is all there is, and nature is composed of matter; the particles making up matter and energy that physicists study.
So, this is the philosophy called naturalism, or materialism. And since that’s all there is, it follows, that matter must have done all the creating that had to be done; that is to say, matter, unassisted by God, or any other intelligent force. According to materialism, a mind can’t exist until it evolves mindlessly from matter.
And so it follows that we are the products of an unguided, purposeless material force; which specifically is called Darwinian evolution when you get to the history of life.
And so we get our information about it (and really, information about everything) from science.”
