This is only correct if human intelligence was aquired through HGT, which, it was not.
What can I say but "no it doesn't"?
To get back to our bacteria, they revert to the wild type in the absence of antibiotics whether the genes are on a plasmid passed around by HGT or whether the genes are on the main chromosome and were not acquired by HGT.
And once you prove that, we will move on.
I believe I have, the penny just hasn't dropped yet.
Okay, then lets discard HGT for the moment, and discuss your evidence for genetic mutation strictly.
Splendid, let's.
Mutation of existing information, be it positive or negative is a good example of microevolution. But you have not shown that these mutations resulted in new, or more complex DNA sequences.
Of course they were new. Because of them not existing in the original strain and then existing after the mutation. That's what "new" means. Heck, that's what "mutation" means.
No, I said genetic loss can result in useless information.
You wrote, and I quote: "Genetic loss would be any sequence of dna that has been changed in any way that renders chemically useless nucleotide arrangements."
The specific mutations we're discussing didn't produce chemically useless nucleotide arrangements. Hence they are not genetic loss.

In a way, you are right. But the origin of the 'new' information is from existing information, for which no source has been explained.
Mutation. Selection.
The old information was once new itself.
I don't think you even have a penny in your pocket. You have shown that HGT COULD explain how mutation is passed around, though this is questionable ...
We can watch it happening.
You have not explained how new chemical arrangements come about by random chance, or mutation.
I have explained that new chemical arrangements come about by mutation.
I really don't see what's confusing you. The word "mutation", or the word "new", or the way that adjectives qualify nouns, or what? The point is an obvious one.
Mutation is the damage, or alteration of the genetic 'message' carried by any gene. This does not offer evidence for the origin of new chemical arrangements.
That is the origin of new chemical arrangements. Not the "evidence for" them, but the thing itself.
Again, I don't understand what it is that you don't understand.
They are also not new. They are changed.
Ah, apparently it is the word "new" that is giving you trouble.
Very well then, according to your apparent idiosyncratic usage of the word "new" evolution does not require any "new" information. Just "changed" information.
If I buy a car, then sell it without tires, is the car new? No, it is missing a specific part for it to function properly.
If you buy a car, and change the tires for ones that have never been used before, are the tires new?
First, you have not shown that.
Yes I have. You have the desciption of the experiments, you have links to the complete papers. You may not have grasped what they mean, but as Dr Johnson said: "I have found you an argument, but I am not obliged to find you an understanding."
Second, though a specific sequence of nucleotides can be damaged, the gene as a whole can still function.
And, in the cases given, function better. So in what sense could they be considered "damaged"?

Re: What's the problem?
If you become any more confused you might end up saying something true just by accident.
This would, I suppose, be an example of neutral drift.

Now wait. You claim that mutation is the source for new information. This is your claim. Now you need to support your claim with evidence.
It is sufficient to support my claim by referring you to the meanings of the words "new", "information", and "mutation".
I can watch someone hotwire a car, does not mean that is the correct way for the engine to start, nor does it explain of everyone starts their cars this way, which they do not, since this is harmful to the car, damaging wiring components.
It would, however, prove that it is possible to hotwire a car.
Nothing. Other than you still refuse to give evidence to support mutational evolution.
This is, of course, untrue.
Explain what mutational processes can account for new information.
The process known as "mutation". I think we can all agree that this is a mutational process.
But not that these new arrangements are useful, nor that this information was not from a previous source.
The example and references I gave do in fact prove that.
What you have not argued is that any useful function comes about from these mutations.
The example and references I gave do in fact prove that.
If you are talking about Micro evolution, you win. But new functional genetic information would be required for macro evolution.
And as we can see, new functional genetic information is produced by mutation.
Loss or damage of any specific nucleotide sequences.
Which did not occur.
You have given me sources for genetic change. In one case, you offered an experiment that was repeated with similar results. This is NOT evidence for random mutation, since the odds of any organism mutating similar to another, if in separate conditions is a huge impossibility.
It's at long odds for any two given bacteria to undergo a mutation with similar effects. But what happens when you have lots of bacteria?
No one is claiming that all mutations are harmful, and anyone that does is silly. But the genetic material is due to a loss of information.
Not, in these experiments, according to your definition of genetic loss, which involved a gene becoming non-functional.
If you'd like to try another definition of "genetic loss", be my guest.
I read back in your posts (to some extent, I don't have all day), the experiment performed by different labs that yielded similar results is out. If random mutation is your claim for the origin of new genetic information, any such experiment would NOT yield the same results, unless the organisms themselves caused the change, in order to survive in harmful conditions of some kind. Random mutation should not be repeatable, since it is RANDOM.
Like throwing a six. Once one person has done it, it can never be done again, because that wouldn't be "RANDOM".
Of course, some people would say that it should happen one time in six, but I guess they don't have your deep and penetrating insight into everything.
If random mutation is your claim for the origin of new genetic information, any such experiment would NOT yield the same results, unless the organisms themselves caused the change, in order to survive in harmful conditions of some kind.
Does the unevidenced, impossible method by which the bacteria achieve this include a faculty of precognition?
Only it is demonstrably the case that mutations can happen, and happen repeatedly, before the bacteria are put into circumstances under which those mutations will be beneficial.
That's 'cos the mutations are random. Or because the bacteria, besides the ability to perform intelligent acts of genetic engineering on themselves, also have the ability to see the future.

Re: The flood myth
Continental uplifting does NOT occur in Egypt. If uplifting does not occur, sea shells should not be found in the desert.
That was ... weird.

My question is: Does this mean the authors are saying that natural selection was not the cause of the evolution of the eukaryotic cell from the prokaryotic cell?
No, natural selection would still be operating --- the endosymbiotes would have succeeded because endosymbiosis was a good idea.
And if true what effect does that have for The Darwinian and neo-Darwinian theory of gradual descent by random mutution and natural selection?
Well, first of all, that isn't the neo-Darwinian theory: the theory incorporates everything that actually happens. This includes mutation and natural selection but is not limited to them.
Second, what has happened is indeed mutation plus selection, plus a bit of lateral gene transfer. The fact that we can "chunk" these events at a higher level and call it "the origin of obligate endosymbiosis" doesn't stop it from also being a set of lower-level events.

"Basicially the problem is that a primitive bacteria cannot evolve mitochondria by 'jugglilng its genes'. It would require that one of these primitive bacteria absorb and adapt by swallowing or absorbing an entirely new cell. On earth this has never been observed happening with prokaryotic cells. However eukaryotic cells indeed have been observed to do this. For a prokaryotic cell to transform to a eukaryotic cell it would have to do things that seem to only happen in eukaroytic cells"
What does he mean by that statement?
Apparently, his reasoning is:
* Only eukaryotic cells have been observed to do what eukaryotic cells are claimed to have done.
* This makes it hard to believe that eukaryotic cells have in fact done what we have in fact observed them doing.
He seems a little confused. Maybe he doesn't realize that there are other biological differences between eukaryotes, archaea and bacteria besides the fact that the former practice endosymbiosis. A eukaryote is not simply an archaean or a bacterium which happens to have mitochondria.

I understand this to mean that the TRANSITION TO COMPLEX LIFE was a unique event that did not rely on natural selection.
No, I think you're reading it wrong. They say that it wasn't produced by natural selection acting on mutations accumulated gradually. But obviously natural selection favored the endosymbionts, or they wouldn't be here. (I assume here that the change was not merely neutral in its effects.)
As to whether they are right about the mutations, it depends on how you look at things. If you conceive of the pre-endosymbiosis eukaryote and the mitochondria as being and remaining two organisms, then you have a fairly normal case of the evolution of symbiosis. If you look at them as becoming one organism, the post-endosymbiosis eukaryote, then the eukaryote received a whole lot of genes suddenly by an unusual form of lateral gene transfer.

Re: Why?
Even if I was the best authority on earth on evolution, and knew more than the most ardent scientific evolutionist, I would still not find evolution to be true.
Well, you never know until you try.
The fact that knowledge of biology is strongly correlated with acceptance of evolution suggests that you might, in fact, find evolution to be true if you knew more biology.
It's as though you said: "Well, if I was the tallest man in the world, I'd have no trouble finding clothes that fit". But the experience of actual very tall men suggests the contrary.

Re: Why?
I think it's natural that if one lives with the Indians one becomes an Indian.
But this relates to no true Scotsman putting sugar on his porridge.
Example; "No true scientist is a creationist".
Well, lots of people have been scientists and have known much more than any of us about evolutin, yet have come to a realization of a designer.
The facts arent evolutionary facts, unless you decide that all evidence is evidence of evolution. It's circular, like saying; Oh how do we know abiogenesis is true? cause we're here! We're here therefore abiogenesis must be true.
Anyway, my own search has led me to value cleverness over general knowledge. Anyone can regurgitate what a textbook says, but I find that clever thinking brings satisfaction in detecting the correctness.
If you increase your understanding of reasoning, you'll begin to realize that all that matters is the soundness of a claim. Not who made it, or what he knows or doesn't know or how much mikey does know or how insane he is.
Essentially, all that matters is how sound, logically, an argument is. This also applies to evolution.
The evidence for evolution is a build up of information based on a conditional implication, used for the reasons of establishing falsification and confirmation, via logic. AT NO TIME whatsoever is there any suggestion that a theory should be believed or accepted, because induction is astoundingly WEAK evidence. (Example, if you pick out a million red balls for red ball theory, merely O N E green ball will refute the theory because of the power of the tollens)
Example;
If evolution is true THEN we should find transitional species preserved in the pre-cambrian.
The tollens is falsification evidence thus;
If they are not there, then evolution is false.
Now what happens is that you can only argue ad hoc as to why evolution is true. Therefore punctuated equilibria was taken up by many IN REGARD to the evidence AGAINST evolution.
This is my eternal frustration - that nobody at EvC actually knows what "evidence" means.
Science by no means would call me willfully ignorant for not accepting a theory - it would actually call me "hyper-scientific". But the PEOPLE call me something else.
Why is that? Is it logic or science that compels them? It is neither!
The occasional bits of this that seem as though they might mean something don't appear to be a reply to my post.

Re: Another test
There are over 200 geochronometers that suggest a young earth.
Some of them are;
The amount of mud at the mouth of major rivers
Light not being a constant
The amount of dust on the moon
Satelites that should have expired
Polystrate fossils
Examples of rapid layers being created in days (Mt St Helens)
I won't go into it all, but it's nothing to do with scientific prowess. Also, potassium argon dating gave rocks found at new volcanoes dates of millions of years.
See, this is where knowing stuff would be a help to you.
Also some better reasoning skills, but that ship might already have sailed.

Re: Another test
Einstein's proposal that if light were not a constant ...
Our train of thought in the foregoing pages can be epitomised in the following manner. Experience has led to the conviction that, on the one hand, the principle of relativity holds true, and that on the other hand the velocity of transmission of light in vacuo has to be considered equal to a constant c. --- Albert Einstein, Relativity: The Special and General Theory, Chapter XIV
Einstein only made c the most famous constant in physics.
