Not sure where you're coming from, Snare. I understood the textbook.
Just pointing out the irony of a textbook that stated it was clearing up erroneous thinking which then caused such a misunderstanding in SpaceMadness.

99.9% Of a People Who Believe In Evolution Don't Understand It.
by Space Madness ini never believed in evolution as i thought it didn't make sense and that what was proposed was simply impossible.
how could an environment alter an organism's dna?
as we can see however, bacteria cannot become resistance to antibiotics.

JW Kids Who Lack Sincerity: Are You In The Flipping Truth Or Not?
by Apognophos indid any of you know a jw youth who didn't seem to really even try to be sincere about the "truth"?
not someone who led a double life while pretending to be a goody-goody jw.
i mean the kind of kid who went to the meetings and did field service while making minimal effort at maintaining a pretense of being a true believer?.

Apog, how do you know they hadn't considered the truth of the religion?

The irony is that the textbook was attempting to clear up a supposedly common misconception and succeeded in creating even more misconceptions.

I beg to differ that I am assigning an intent not given in the quotation.
A thorough reading of the rest of the textbook would make the meaning very apparent, as long as Space is truly quoting from a university level college textbook of biology. Understanding the entire subject (as I and other members of the board do) makes it quite apparent what the meaning of that sentence is.

There appears to be a reading comprehension problem with the quote. Let's read it again.
"Many people mistakenly believe that antibiotics create resistance; that is, that resistance arises in bacteria in response to exposure to drugs."
The structure of the sentence is that the first statement is then clarified by the semicolon and the words "that is."
The second statement says that "resistance arises in bacteria IN RESPONSE to exposure to drugs." This is the fallacy: that the bacteria are RESPONDING TO the environment and CREATING resistance, as the first part of the sentence states. It is NOT stating that there is no such thing as bacterial resistance.
With a basic understanding of the subject, you can easily understand which words are being stressed in that sentence.

I think a problem is the title of the thread.
In general, people who believe in evolution understand it very well. It's the disbelievers who have a faulty understanding of the mechanisms involved who then use that as an excuse to disagree, like you mentioned you yourself used to do.
Plus, it's disingenuous to use a made up statistic like 99.9% when what is really meant is "the majority " or something similar. Statistics should only be used when they are actually real. We all do it from time to time, but it's a poor use of language.

Space, it's responded to its environment in the sense that the current population has only come into existence within the conditions of its environment.
Again, population versus organism is an important distinction. When I say species, I mean the total population of a particular species.
You'll get there. Keep reading and thinking.

"You don't pee next to a cop," and other rules from the mens room that women don't know
by GrreatTeacher ini was recently at a baseball game with friends and family when i learned something new.
beer had been drunk and the men made their way to the men's room to relieve themselves.
when they got back i asked them what took them so long.

I think the niceties are to distract from the real business at hand, so we can pretend that we really are going into the restroom just to rest and then style our hair and fix our makeup. Its all part of the voluntary delusion we share that there's really no pooping going on in there, no siree.

Okay, off from bacteria and their antibiotic environment and on to animals and their environments.
A large predatory bird usually eats fish. A mutation produces an extra talon that can be used in an opposable way with his other talons and becomes useful for catching and eating rodents. This becomes beneficial to the bird allowing more food security and more stable nesting and reproduction opportunities. His offspring will now have twice the variety of food and therefore be more fit for reproduction and so the extra talon, giving an edge to survival would remain in the population and become more prominent. Then, the bird could move farther inland and eat a diet of small rodents exclusively. Eventually the extra taloned bird who lives inland becomes a separate species from the water living birds who eat fish. Any extra mutations that allow the inland, rodent eating birds better survival could further differentiate the two species.
That's just a possible example. Think of a peacock trying to attract a mate. The environment is tough. If a peahen doesn't choose you, none of your genes get passed on. Then one day a peacock is born who has a colorful tail. More peahens chose him and so he gets to pass on a lot of his genes. Then another genetic mutation produces a longer and colorful tail and the peahens find him extremely attractive and he passes on even more of his genes. So the long colorful tail is spreading through the population because it is being selected for reproduction by the females. Thus, the peacock species eventually has very long and colorful tales in the male. It has adapted to the environment of female preference.
So, again, there are no genetic mutations in response to a particular need. Previous genetic mutations that are useful for survival in a particular are more likely to survive and thus pass on those genes to their offspring. Thus, the species has changed or adapted in response to its environment. Again, on a population or species level, not on an individual organism level.
