The genetic materials in bacteria can mutate and some bacteria are no longer killed or stopped by antibiotics.

I agree, but this has nothing to do with evolution. This is an example of a bacteria losing information, not gaining information. It is still a bacterium. If this is the best evidence that somebody has for evolution, then they need to re-examine the logic behind holding to this illogical position.

"Losing information": What? It's evolution. It's not 'information', it's adaptation, and the formation of new species of bacterium. That's exactly what evolution is. Where's the illogic? Read a biology textbook, write out some notes, and come back.

Have you ever wondered how a bacteria can do this? Lets take this up a bit to aphids. Aphids adapt to various insecticides at a pretty rapid rate. Why?

Ok, you put out the insecticide. You kill 99% of the aphids. Good job, you no longer have an aphid problem. However, those 1% of the aphids survived. Why? The insecticide did not work so well on them. They are more resistant to that insecticide. Well, no problem. You killed off most of the population and now your roses are doing great. However, those in the 1% category will breed. Their offspring will inherit the resistance to the insecticide. Since aphids breed pretty quickly, it does not take much time till you have a population that has some resistance to the insecticide that you are using. Repeat this process enough times and you will get aphids that have so much resistance that the insecticide becomes useless.

At no point did the aphid (the same holds true for the bacteria) gains or loses information. The aphid does not know about insecticide and it has not learned a way to cheat it. Some just naturally are resistant to it.

One of the basic parts of natural selection is that those with favorable traits for their environment have a better chance to survive and pass those traits on to their offspring. Those without those traits (or traits that are unfavorable) would have less of a chance. Given enough time, all of the species would have the trait.

I know this is useless, but I'll give it a shot:

These bacterial mutations occur over a short period of time; it may be observed year by year, and documented by scientists.

Give these mutations enough leeway and time (i.e., millions of years) and eventually any species' genome will turn (evolve, that is) into a whole different species, such as horses/zebras, chimps/gorillas/people, or the different types of spiders.

The problem with you guys is that you regard Humans as the finished product, and therefore demand that science provides you with the in-between evolutionary draft.

Evolution does NOT stop at a point, since it is NOT a race towards an end. It is simply changes, mutations.

I wonder how many theists have actually read Evolutionary texts. No wonder you still regard Darwin as the only Evolutionist.

Actually, you are 180 degrees incorrect.

A bacteria that mutates into something that is resistant to a antibiotic NOW produces enzymes (like Penicilinase) that will prevent the antibiotic from interfereing with it's biological processes. It GAINED genetic information that it never had before, not lost it.

The only common examples of information loss (which is still evolution if it makes for an organism that can take advantage of it's environment more easily) is that of internal parasites.

You're lack of biological knowledge is breathtaking.

What about Simian Immune virus that has mutated into Human Immune Virus? That's another example of evolution - did the viruses lose something?

Actually, in most cases it's an information gain. Usually in the form of acquiring a gene via plasmid. Even in the case of INH resistance in M. tuberculosis, the point mutation does not create information loss.

Of course, in a classic study of mutations in bacteria, beneficial information increasing mutations were far more common than anticipated.

"This is an example of a bacteria losing information, not gaining information."

WTH are you smoking?

To gain antibiotic resistance a bacteria normally develops new defense mechanisms, and adds to it's genetic code. It is not like it is coded into it's genetic structure that penicillin kills it, it is a weakness in its genetic structure that is "fixed" over time. It does not loose the "penicillin death" coding in its genetic structure, it gains new things that allow it to survive in an environment where the hostile chemical is present.

This is not the best evidence for evolution, just one we use as an example because theists can understand. Also, yes, it is in fact the essence of evolution because it is a minute change that occurs as a response to environment.

Besides this post, I've never heard any evolutionist ever claim that as defining proof, as opposed to the hordes of other proof.
And just a tidbit of information- they dont loose information- Just the way our bodies develop an immunity to certain diseases, the bacteria develop an immunity to antibiotics. It's adaptation, not evolution- there's a diffrence.

Actually it is an exchange of information. Some genes are replaced some are removed and some are inserted changing the genome. But you say your self the bacteria changes over time. Evolution is the process by which an organism changes over time so this is one of many examples of evolution. Say no to jesus

The gene for amoxicillian resistance often comes from duplication of another resistance gene (error in transcription) and then subsequent changes in one or the other copy.

This would represent gain in information.

-------

Abdul: In the idea that DNA codes information, he is correct. Since each codon contains one of four possible values three times, it contains 4^3 or 64 bits of information, though many of these are redundant (many codons code for the same amino acids).

What he fails to grasp is that it is very easy to add information by duplicating a gene one or more times. Then one can change since the remaining functional copy still provides necessary functionality and the other can drift without necessarily causing injury.
