Also don't confuse "evolution" with "The Theory of Evolution".
Originally posted by jaywillI think we have always distanced ourselves from extending the scope of the theory over the problem of the origin of life (the first self-replicators). So the initial challenge still stands.
I think your objections and those of whitehead prove exactly my point. Of latter times Evolutionists like to distance themselves from extending the scope of the theory over the problem of the origin of life.
And Hoyle said if it cannot include this initial set up of life the theory lacks a proper foundation.
I think I need to see the full context of that Hoyle quote (was he a biologist?). You could use it to discredit most of science: "gravitational theories lack a proper foundation because we don't know what causes mass". In the end, everything we know is based on the assumption that the universe came into existance and, since we don't know exactly how that happened, we should throw out all of science. Does that sound like a good idea?

Actually, maybe we are trying to refute that pre and post biotic evolution are different. They are both Evolution by Natural Selection. To say that they are different would be a bit like saying Pre-Mammalian and Post-Mammalian evolution are different.
Once the first self replicators appeared, natural selection would have worked on them and Evolution by Natural selection would have occured (and is still occuring to this day).
Before the first self replicators appeared, Evolution by Natural Selection could not have occured and therefore can not be responsible for their first appearance. That has to be covered by another mechanism. Hey, maybe GodDunnit?

Originally posted by PenguinIn fact, the Theory of Evolution even when talking about the situation today includes non-life. Virus's evolve just as readily as most life forms. Virus's would probably be called 'biotic' but they are generally not considered 'life'.

[b]++++++++++++++++++++++++++++++++
The theory of evolution combined with the fossil record implies that there was single cellular life on earth sometime in the distant past.

The fossil record tells us only one thing for certain:
There use to be on earth a lot of animals which apparently no longer exist.
...[text shortened]... posed to explain why the fossil record is not more supportive around a century latter.[/b]
The maximum possible resolution you'll get from a fossil record is about 10 - 100 thousand years. It's been calculated that that a mouse, increasing in mass by only 0.5% per generation could reach elephant size inside of one of those strata - how are we supposed to "see" every fine gradation? That's all Gould missed out on - there is no need for a saltationary event when normal evolutionary divergence will do just as well.
In short, PE is a defunct hypothesis, which had little real evidentiary backing when it was published, and has subsequently been demolished by Dawkins et al.

Originally posted by jaywillHe's right, but you are taking him out of context. Selection can only exist when there is something to select between. A replicator, however, simple must have existed before selection between replicators could occur. That stands by very definition.

The following quote laments that evolution theory is incomplete because of the origin of life problem not being solvable by the evidence for the theory. I take "incomplete" foundation to mean that the theory should also account for the origin of life in order to have a proper foundation:

And if there is further doubt "SPANTANEOUS GENERATION" is spelled out for you.
Anyway, spontaneous generation in this context only means spontaneous generation of a self-replicating chemical in a reducing environment. Heck, I can do that in a chem lab in an afternoon. The planet had a 100,000 years, and a planet sized test-tube.
Originally posted by jaywillHoyle was an idiot though. Ask Stephen Hawkins.
I think your objections and those of whitehead prove exactly my point. Of latter times Evolutionists like to distance themselves from extending the scope of the theory over the problem of the origin of life.
And Hoyle said if it cannot include this initial set up of life the theory lacks a proper foundation.
As for "evolutionists distancing themselves recently, well, this is patently false. Darwin did it, in "Origin". Since them we've came a long way. Dawkins discusses numerous hypotheses, all under investigation, in his books.
You should read them.
Originally posted by jaywillJust thought I'd bump this since we've now had a page of me, Scottishinnz and TWhitehead agreeing with each other and Jaywill seems to have gone silent (we all have to live lives outside these battlegrounds).

So is Jaywill willing to accept that being unable to explain the origins of the first self replicators does not invalidate the Theory of Evolution by Natural Selection?

Originally posted by twhiteheadNo. I am saying that both areas of inquiry come under the overall umbrella of Evolution.
Are you saying that Pre Biotic Evolution and (ie. Post Biotic) Evolution are two separate contradictory theories?
Also don't confuse "evolution" with "The Theory of Evolution".
There are those apologists who are careful to restrict Evolution to only biological matters.
There are those Evolutionists who are more general to include pre-biotic and biotic aspects as all wrapped up in a idea into which they place much hope - Evolution.
Then there is much of the unscientifically trained public who have been inundated with ideas that both pre-biotic and biotic areas are both Evolution.
Read again Dawson's comment written around 1890:
"Evolution sometimes professes to explain the origin of things; but of this it knows absolutely nothing ... This is ADMITTED in terms by Darwin and his followers, BUT CONSTANTLY OVERLOOKED IN THEIR REASONING, IN WHICH EVOLUTION IS SPOKEN OF AS IF IT WERE, OR COULD BE AN EFFICIENT CAUSE."
My Emphasis.
