Evidence please. Evidence must be something we can see, taste, smell or touch-and must be repeatable and predictable.

One of his questions was, where are the false starts? What you are showing here are not simple small mutations to one small part of one bone, that could start a revolutionary new trait if NS would select for it. So the examples you showed do not support the ToE, they rather contradict it, because what they show is that each time you have a gross mutation, it is damaging to the organism. Nature has lots of examples of gross damage mutations can cause-we are asking for examples of positive ones-which your theory needs quite a lot lot lot of.

Ok, so let's be perfectly clear then. You are now saying (contrary to your see, smell, taste, touch demands) that rational inference is as good as any for drawing the conclusions one wants to draw, and we really don't need to be hamstrung by the whole see, taste touch, smell evidence burden.
Instead what we can just say that RM and NS are probably happening today (no need to prove this either) and leave it at that. Please try to be consistent for the level of demand you require for evidence in the future then is the least we should ask. But anyway, I guess you do have lots of evidence for RM and NS in todays world? It must be common as heck right? We can see it all around us, right?

Did you create a new type of organism or something? I missed that in your lofty experiment. As I recall, you simply used an agent to accelerate mutations to a bacteria. Whoaaa.
Is that the best ya got? Sorry, if I don't appear so impressed. Did any of the bacteria grow eyes, or a left toe? You might have gotten my attention a little better if that happened. Any random mutations for echolocation? A spleen? I guess a mind like yours doesn't require much to convince it does it?

So why should anyone be impressed by a theory that has as its only claim for evidence, a few cases of a bacteria staying a bacteria, and then after a while staying as the exact same bacteria, and then after a zillion generations,more, staying....you guessed it, bacteria.
If all of the things that your side claims as evidence for evolution, continued to proceed in exactly the same progression as witnessed by the evidence, not a single organism would ever change into anything in a billion zillion years. That is the only rational inference anyone who is honest could make about the evidence. A bacteria is not going to stop being a bacteria just because it changes its diet. Note: Honest doesn't include you. Edited by Bolder-dash, : No reason given.

Then I think in a fair debate, from the beginning you should just admit that there is no way to produce evidence for Rm and Ns, and be clear that any suggestion of these mechanisms is simply inference as you said.
Anyway, since that is what you are saying now, let's nail down this point so we don't keep changing goalposts.

So we can agree that your experiment, regardless of what you ware claiming is happening, can provide no evidence whatsoever for the development of any new system or organism, correct?
We won't get a new bacteria, or the start of a new feature to an organism, and we basically won't have any evolution at all, if all that happens is what happened during your experiment. A bacteria that changes its diet is still a bacteria. For a zillion generations.

I have already said that mutations happen and that natural selection happens-people smoke cigarettes and get mutations, and nature might select them either for dying, or from dying because of this condition (the funny thing is the cancer selects them for both.)
The point is not to show that these two functions might have happened, the point is to show that they actually accomplish anything meaningful towards developing life. This you, and everyone else here, and every scientists in the world, can not in any way at all demonstrate. That makes your theory nothing more than fairy tales.

Well, here's one reason for some incredulity; you say random mutations could have caused lubricant forming between joints, or proto-cartilage could have randomly appeared that would have caused some reproductive advantage. But we never see examples of these things happening occasionally in modern species.
We don't see sporadic examples of people born with excess cartilages in random areas, or lubricant forming between some peoples finger joints, or extra ligaments appearing in some individuals which causes some difference of their physical capabilities. So if we can never see this happening occasionally why do we just have to take your word that it did? But more importantly, why are you constantly shifting the burden on the skeptics to just accept what you say without proof, rather than putting the burden on the one's making the extraordinary claims to provide some extraordinary evidence. Or any evidence for that matter. You are making baseless claims that you can't verify, and asking others to just accept it.

Perhaps I wasn't clear enough, maybe that's my mistake, but I thought the implication was obvious enough.
Mutations which could possibly, with even the greatest stretch of imagination, actually BENEFIT an individual in the right circumstances. Mutations which could actually cause a different mechanical functioning. A unique physical function. I don't think a tumor counts as a unique physical ability. I am pretty sure arthritis, or pituitary abnormalities are not the origin for any new limbs-now or in the past. Or a congenital deformity that doesn't even effect the victim until later in their life. Besides the fact that I don't believe even one of the things that you mentioned are the type of point mutations that could be carried on to offspring at a specific location. But still, it does say a lot when your side thinks these are the examples that shows that Darwinian evolution could be true. Extraordinary really. And you still believe in your theory?

I have asked repeatedly for you to produce the evidence, any evidence, that a random mutation caused the beginning of a new functioning limb or system.
You can't do that. Mobiogirl it seems just tried, and I don't think anyone could call that a success. You have evidence of what you feel is common relations, you have absolutely no evidence for the mechanisms that caused complex functioning systems. So when you lie, like you are doing right now, Dr. A, it makes one wonder what your real motive is.

I believe in adaptation, you got me there.
But since I live in Tibet, I am glad you brought this one up. Please tell me what was the point mutation that a Tibetan got within the past 5000 years, that was then selected for over a series of generations, with those without the mutation being rejected by natural selection, until it spread to all the inhabitants of Tibet (and Qinghai). Walk me through this one if you would. And since the topic is about skeletal systems, and the like, please walk me through how this "random point mutation" that you are going to tell me about relates to building a new skeleton, limb, or complex new trait.

Bolder-dash - please take these issues to your New name for evolution, "The Bacteria Diet" thread. --Admin
So talk us through this Melindoor, what do YOU personally think the first mutations to those primitive fish without any skeletons at all would have looked like? Here was this soft fleshy kind of fish thing, that had no spine, and no bones of any kind. And then what do you think that very first mutation that started the whole process out looked like? Was it a piece of bone near where the spine already was? Or was it a piece of bone that started off somewhere near his belly, and then over time and many generation slowly migrated over towards his back? Do you think those early first fish with the bones near their stomach looked silly, compared to the others? Do you think the other fish laughed at him, or do you think the female fish decided he was special, and so he got a good selection advantage, and that is why more fish ended up with the bony stomach? And then, by the time it got close to his spine, to actually protect his spine, do you think that the part near the stomach started shrinking in successive generations, because by then all the men had bony stomachs so the girl fish no longer felt it was very sexy? And then, do you think the girls started choosing the guys with the bony back, because they knew one day they would have bony back children themselves, and they knew that that bony back would be a big plus in case they bumped their spines on some coral that was just started to form a few miles offshore? Do you think they knew about the spine protection it was going to give them, or do you think they just sensed it? And what about back to that first guy who got the bony stomach mutation-do you think he is sort of famous throughout the entire marine world, as the guy who started off this whole darn bone race? Do you think there is an underwater Hall of Fame for the skeleton starter? Might we even find his fossil remains one day, and have him hung in the museum of stomach bones? And how often do bony stomach mutations happen these days anyway? Are they passe? So what do you think? Do you mind painting the picture? Edited by Bolder-dash, : No reason given.

I am trying to figure out what your color analogy has to do with anything regarding evolution? Is there something applicable between our photo receptors perception of colors, what our brains call things that look slightly similar, and what is the difference between species?
From far enough away a planet and a star look exactly the same to me, and from close enough up I can't tell the difference between a bread-crumb and some paint (and it doesn't even matter what color the paint is). I don't think we can gain much insight into evolution from this knowledge.
