When you author and publish a biology textbook that's reviewed by other biologist I'll take your word for it. As for now I'm going to side with the experts over you.

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.

If you have added to the list people who think antibiotics have led to bacterial resistance, YOU ARE IN THE WRONG, they did not evolve the resistence before the exposure to antibiotics. The enviroment selcts the genes, antibiotic use alters the enviroment. You have misunderstood the textbook.
What you said makes no sense. If no bacteria is resistance prior to the creation of the antibiotic than all the bacteria would be destroyed. Let's revisit the text : " In reality, genes do not “know” when to mutate; the chance that a mutation will occur is independent of whether a new phenotype would benefit the organism. The only way antibiotic resistance arises is if some bacteria happen to have a mutation that confers antibiotic resistance before exposure to the drug."
You're reading comprehension is appalling.
Actually your assumptions about me don't really hold any water. I am not in the medical field.
The post wasn't directed at you. Why would I assume you're in the medical field?

99.9% may seem absurd to you because you're in the medical and most the people around you understand evolution. In any other field and in most colleges 99.9% don't understand evolution. I have been in plenty of debates with college student majoring in political science, psychology, journalism, or any other Arts major who are hardcore believers in evolution but knows nothing about evolution or biology in general. If i was to amend my estimate, I would drop it from 99.9% to 99.2%.

@GrreatTeacher
That was never my point. My point was antibiotic resistance bacteria are not the result of a response to antibiotics. I clearly state that in my second post when I responded to Apognophos.

You are so confused so allow me to clear things up. When I said I never believed in evolution, I'm saying I never believed in the evolution as defined by the laymen. The ones that believe bacteria respond to antibiotics, that DNA mutations are a response to the enviornment instead of being random, and the whole "survival of the fittest" misconception. After taking this biology course, I found that the theory of evolution is very different from what the laymen say it is and that biologist have a different idea of evolution than the laymen. I find the theory of evolution as defined by biologist to be much more plausible and agree with the majority of it. When I say laymen I'm not necessarily referring to anyone on this site but the general public. On college campuses the vast majority of college students believe in evolution. Outside a few biology, biochemistry, and chemistry students, hardly any of them understand it. That at least has been my experience in the United States. You can go on YouTube right now and watch a bunch of videos of people trying to explain evolution and it will not reassemble anything biologist believe. Even well known celeberties who act as spokesmen for evolution don't understand it. Evolution as defined by biologist is nothing like the evolution defined by the general public. You seem to think I'm disagreeing with biologist when in fact I am agreeing with biologist and disagreeing with the general public. Do you understand now?
The point of this thread is that evolution is misrepresented by the general public which caused me to question it's validity. After learning from actually biologist, I come to accept the vast majority of the theory of evolution.
P.S You are clearly not reading my post. If you read my second post you can clearly see I was never arguing that bacteria can think or that biologist believe they can think.

@Apognophos
The majority of laymen believe evolution works that way. That's not just my opinion, several others on this thread have pointed that out as well.
@snare&racket
I don't understand your post? After you quote me you say "now you are claiming otherwise". What am I saying differently now from the paragraph you quoted? I still don't believe an environment can alter an organism's DNA nor do I believe bacteria becomes resistance to antibiotics due to exposure.

It appears you haven't read my post. You keep telling me to pick up a textbook but the majority of my OP is quotations from a textbook. Also I explicitly stated that it is impossible for DNA and bacteria to think, as some people suggest with adaptation to an environment and bacterial resistance.
@cofty
I'm honored by your response. I've seen many evolution threads and you always rip people to shreads who question or express any doubt in evolution. The fact you showed respect to my opinion and even gave me a compliment is encouraging. Not surprisingly I find your response to be the most insightful. Perhaps the majority of confusion stems from using short handed language, or maybe I'm just being too technical.

That second quote was from the textbook, not me. If they felt the need to include that in their publication than it safe to say they heard that argument from plenty of people. You're not a biologist, the people who authored and proofread the textbook are, I'll take their word over yours that plenty of people erroneously say their is "need" in evolution. Also I used the "organisms" (with an 's') to cover all living things such as animals, plants, insects, bacteria, etc. I used the word corectlly but you obviously didn't know that, possibly because you never went to college.
@GrreatTeacher
You said " Thus, the species has changed or adapted in response to its environment." How does your example show change that was a response? ALL genetic mutations are random, how can DNA respond to an environment?
@kaik
UV lights cause somatic mutations, not germline mutations. If a person is exposed to too much radiation they will develope cancer, which is a mutation of somatic cells. The cancer will not be passed to the offspring if the DNA in the germ cells (sperm and eggs) where not affected. UV lights cause somatic mutations like skin cancer, but they don't affect germ cells, which means any mutation experienced by UV lights will not be passed to the next generation. To put it plainly, when a person gets skin cancer from UV lights, their children are not going to be born with skin cancer.

You're completely misunderstanding my post. The "evolution" that biologist speak of is nothing like the "evolution" that 99.9% of believers speak of. Secondly natural selection does exist, but it is not due to animals adapting to the environment, which is impossible. Concerning the rest of your post, I never said environments don't change. Ecosystems and biomes are a completely different topic that I'm not interested in discussing. Also can you explain to me your understanding of natural selection?
