Re: another rather typical misconception
Obviously, plausibility does matter when it comes to science.
It does matter, especially when something is proven fact in the face of how improbable it seemed to be. Like with CS's example of the calcium atoms.
There are countless instances where plausibility is taken into consideration to choose one hypothesis over another, so I don't understand why you say that "plausibility doesn't really matter."
He didn't say plausibility doesn't really matter. What he said was probability in the case of the calcium atoms didn't really matter. The calcium atoms are in his arm bone and originated in a star in spite of how improbable that may be.

Re: another rather typical misconception
When you look at all the details, the scenario he outlines really isn't improbable.
Yes, when you know ALL the details it's not so improbable any more is it?
I believe that was CS's point.
There's a reason why probability is used in science.
Of course there is. No one is saying there isn't a reason.
But probability obviously matters when it comes to biological origins
It does in the general study of biology, to make predictions, etc. But, not in the sense that something couldn't have happened just because it seems improbable.

Re: another rather typical misconception
And sometimes when you know all the details, the proposed mechanism for a given phenomenon results in that phenomenon's occurrence being improbable.
Maybe you just don't know all the details...
But if it is demonstrated that the proposed mechanism for their origin is improbable/implausible, then the efficacy of that mechanism is cast into doubt.
I would imagine there would be another mechanism proposed to replace the one demonstrated not to work, like with Newton/Einstein physics. There may simply be not enough known about how the mechanism works. I mean, even Newton didn't understand everything about the nature of how the planets moved and said god had to be involved somehow. Then along came Einstein, and well, the rest is history.
However improbable it may have seemed to a genius like Newton, Einstein showed just how easy it worked with new equations.
If an particular improbability leads one to throwing their hands up and saying "It had to be God" then said person has not done enough work to understand whatever it is they're looking into.

Re: another rather typical misconception
So the great deal of sequence similarity between human and chimp genomes could be due to convergence, rather than common ancestry? Because, ya know, we don't know all the details, so we can't rule out convergence?
You can research whatever you want to research. If you feel convergent evolution is a better explanation than common ancestry knock yourself out. We'll see you at the end of your study and your peers will review it. I'm sure if you prove convergent evolution vs common ancesrty there's all kinds of rewards nerds will give you.
What is the consensus so far?
When was the last time I said that?
Not you, specifically, that I know of. At least not in this thread. But some will use improbability to support intelligent design or some other nonsense.
I concur.
Then improbability is irrelevant.

Re: another rather typical misconception
The reason I don't think so has precisely to do with probability -- despite the fact that we don't know all about genome evolution.
Nothing else? Really?
Improbability or implausibility of a hypothesis is not enough to support an alternative model; it is simply enough to cast the hypothesis into doubt and intensify efforts to look for other explanations.
That depends on WHO is making that determination and what they're using as evidence to reach that verdict. I mean, ALL hypothesis have a level of doubt surrounding them. That's why they're just a hypothesis. But just saying "it's improbable" doesn't suffice, because, with every hypothesis, not all the details are known.
It's perfectly relevant to gauge the robustness of a particular hypothesis for the origin of a given system.
Hypothesis by definition aren't complete theories, so improbability isn't relevant. We don't have all the details yet, like in my example of Newton, so it may seem improbable for now but not once we have all the details.
Remember the calcium atom ending up in CS's arm? How improbable would that seem had solar fusion being a vaguely understood hypothesis? Highly improbable! But, as you detailed, not so much once we figured it all out.

Re: another rather typical misconception
You may not be understanding me...
Of course just saying "it's improbable" doesn't suffice; one must detail reasons to support that thesis.
Even if you detail why something is improbable, you may simply lack all the information and are drawing the wrong conclusion.
Because, ya know, improbability isn't relevant.
You've missed the point.
How improbable something may seem is not relevant. However, of course I recognize that certain aspects of science use statitics and probability to determine certain factors.
But that has nothing to do with the points being made to you.

Re: another rather typical misconception
How do you determine when (a) we lack all information, and (b) we don't?
When we don't yet have a theroy and are meerly trying to compose different hypothesis.
Those "certain aspects of science" use speak of include population genetics and evolutionary biology.
Maybe I'm not being clear enough.
Let's look at CS's example of solar fusion leading to calcium in his bones. Before a workable theory of solar fusion, gravity, planet formation, and knowledge of chemistry this would have seemed highly improbable.
But that improbability was irrelevant. The fact is, solar fusion and the cosmic explosions of one specific star lead to the calcium found in one persons (CS's) right arm (for example).
And that improbability would have lead to hypothesis of intelligent design and gods and all sorts of nonsense.
