there is however proof that mutations can be detrimental to an animal. remember the fruit fly experiments?

again. we are talking about proof....
im simply saying the articles you provided offer no proof...

They offer the same sort of 'proof' (i.e., evidence) that supports your claim that mutations can result in detrimental outcomes.
So, you essentially want to fall back on the tentative language of a scientific paper? I see this a lot when a creationist claims are challenged. The papers contain evidence to support their inferences. No science is 100%.
We can't really talk on the level of absolute truth and non-truth, so we have to get mucky in the realm of reasonable evidence-based positions. And it is clear that mutations forming new genes (and functions) is a very very reasonable position, well-supported by evidence (not just this one article).
This entire complement of human genes, it was believed, resided in only around 1.5 per cent of the cell's DNA, prompting some scientists so dismiss vast swaths - the other 98.5 per cent - as "junk".
Now the most exhaustive probing of the genome to date, a £20 million pilot project, suggests the meaning of DNA's message remains elusive. Professor Steve Jones, of University College London, describes the seismic implications of the new findings: "I once wrote a book called The Language of the Genes, but now biologists are beginning to face up to the uncomfortable truth that they have only been looking at the nouns in life's lexicon - the crudest and most basic elements of any tongue.

Contrary to the assertions of some,6 the presumed temporal persistence of supposedly-useless pseudogenes actually constitutes a serious problem for evolution. The manufacture of DNA is energetically costly to the cell, and natural selection should remove DNA were it actually useless.13 A mechanism for removal is now known.14 creationontheweb.com...

The very second God is willing to show up and verify his existence I say we abandon the whole evolution argument altogether.
How soon can this be arranged?

False prophets declare, "Thus saith the LORD," when in fact they have not been sent by Him, and when in fact He does not speak through them. The Scriptures expose such men (and I might add women) as diviners. That is, they pretend to speak that which is divine. While prophecy comes with the word of Jehovah, divination comes with its own philosophies or its own predictions. And it does so while pretending to come in the name of God! That too is nothing less than taking God's name in vain.
Logically, no number of positive outcomes at the level of experimental testing can confirm a scientific theory, but a single counterexample is logically decisive: it shows the theory, from which the implication is derived, to be false. Popper's account of the logical asymmetry between verification and falsifiability lies at the heart of his philosophy of science. It also inspired him to take falsifiability as his criterion of demarcation between what is and is not genuinely scientific: a theory should be considered scientific if and only if it is falsifiable.

Besides, most decent scientists would not ever say that something has to be 100% proven. This allowance for new data or information is the reason science articles and papers are written in that tentative tone that is often jumped upon by creationists
In science, things can be ruled out with certainty, but because of the possibility of hidden variables, proving something "100%" is not generally considered possible.

Having a virus build up immunity does not mean it deteriorates. We ourselves build up immunity to things such as the common cold. Ever wonder why we get colds all the time?

Adapting does not degenerate any living organism's genetic information, where'd you hear that???
Do some research on methicillin-resistant Staphylococcus Aureus (MRSA).
or, you could look into the influenza virus which mutates all the time, that's why we have to keep getting new flue shots ever flu season.

The science: what did they find?
In a paper published in the Proceedings of the National Academy of Science, Lenski and co-workers describe how one of 12 culture lines of their bacteria has developed the capacity for metabolizing citrate as an energy source under aerobic conditions.3
This happened by the 31,500th generation. Using frozen samples of bacteria from previous generations they showed that something happened at about the 20,000th generation that paved the way for only this culture line to be able to change to citrate metabolism. They surmised, quite reasonably, that this could have been a mutation that paved the way for a further mutation that enabled citrate utilization.
This is close to what Michael Behe calls ‘The Edge of Evolution’—the limit of what ‘evolution’ (non-intelligent natural processes) can do. For example, an adaptive change needing one mutation might occur every so often just by chance. This is why the malaria parasite can adapt to most antimalarial drugs; but chloroquine resistance took much longer to develop because two specific mutations needed to occur together in the one gene. Even this tiny change is beyond the reach of organisms like humans with much longer generation times.4 With bacteria, there might be a chance for even three coordinated mutations, but it’s doubtful that Lenski’s E. coli have achieved any more than two mutations, so have not even reached Behe’s edge, let alone progressed on the path to elephants or crocodiles.

but it’s doubtful that Lenski’s E. coli have achieved any more than two mutations, so have not even reached Behe’s edge, let alone progressed on the path to elephants or crocodiles.
I think the results fit a lot more easily into the viewpoint of The Edge of Evolution. One of the major points of the book was that if only one mutation is needed to confer some ability, then Darwinian evolution has little problem finding it. But if more than one is needed, the probability of getting all the right ones grows exponentially worse. "If two mutations have to occur before there is a net beneficial effect — if an intermediate state is harmful, or less fit than the starting state — then there is already a big evolutionary problem." And what if more than two are needed? The task quickly gets out of reach of random mutation.
The first was an enabling variation at around generation 20,000; the second was an initial mutation that actually allowed slow citrate uptake at around generation 31,000; and the third was a refinement at generation 33,000 that made the bacteria grow much better on citrate. Note: 3 mutations had to occur to produce the visibly better growing citrate+ population.

At face value, this appears to be tautologically true, but misleads since “evolution” is a word with many connotations including change, and development to better, more complex replicators. Let us rephrase. Assume three conditions hold:
(i) A population can replicate for many generations
(ii) the copies are not all identical with the original
(iii) a criterion establishes preferential selection of one lineage
What results? Change, yes. More sophisticated replicators? Not inevitably. Suppose the original state was optimal at some point in time and all subsequent variation degrading.
Differential fitness would select the less damaged on average, but the long-term outcome will still be an inferior population. Dennett’s criteria do not ensure neo-Darwinian processes result

Archaeopteryx - a classic transitional form between dinosaurs and birds - was discovered, and in the 1870s the iconic sequence of fossil horses was documented.
CORVALLIS, Ore. - Scientists today announced the discovery of the oldest animal ever known to have feathers, which may have been the ancestor of birds but clearly was not a dinosaur - a discovery that calls into serious question many theories about an evolutionary link between dinosaurs and birds. osu.orst.edu...

So you're ignoring the fact that the article you posted and Behe himself are completely wrong in their interpretation of the study?
We need some heavier goalposts round here.

Con, you've just posted an excerpt from some creationist tripe which was completely wrong. It was based on Behe's tripe, which was also wrong.
The study pulls apart his claims. Three mutations, new function, no magic need apply.
I just saw the post you made earlier, but there's no real point replying. Why bother? When I show your claims to be wrong you'll just go all Nadia Comaneci on me.
Have fun, con.
Giving up on reality
According to biology professor Dr Scott Minnich,1 the evolutionist researcher Dr Richard Lenski bred bacteria for more than 20,000 generations with all sorts of selective environments in the hope of getting a spontaneous increase in complexity—i.e. real evolution in the lab. He showed that they adapted to their environment, but the experiment failed to demonstrate the emergence of true novelty or spontaneous complexity. The bacteria were not only still bacteria, they were the same types of bacteria. So, says Minnich, he decided to work on digital organisms instead—computer simulations, which gave him the result he wanted in 15,000 generations.
The lesson is clear: the real world of biology is very different from the carefully set up and manipulated world of electronic on-screen simulations.

When they begin to talk about mutations, evolutionists tacitly acknowledge that natural selection, by itself, cannot explain the rise of new genetic information. Somehow they have to explain the introduction of completely new genetic instructions for feathers and other wonders that never existed in ‘simpler’ life forms. So they place their faith in mutations.
In the process of defending mutations as a mechanism for creating new genetic code, they attack a straw-man version of the creationist model, and they have no answer for the creationists’ real scientific objections. Scientific American states this common straw-man position and their answer to it. creationontheweb.com...
