I wasn't asking about bacteria, as we don't seem to disagree on that point. I was asking about animals and their environment. How exactly would an animal adapt to its environment on a genetic level?

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.

Natural selection is definitely not the only way organisms evolve. Organisms can evolve through mutation, non random mating, gene flow, and genetic drift. I don't really see the point of me reading basic commercial books on evolution when I'm taking in depth college courses on the subject. Also can you define natural selection for me? im not sure the books you mention have the same definition as biologist.

Species can't adapt to their environment because as the text state: "No known mechanism allows the environment to tell DNA how to mutate... ". This means it's literally impossible for a species to adapt to an environment as you claim. Feel free to tell how you believe it is possible for DNA to know the environment and more importantly how does it make changes to adapt?

Antibiotic resistance bacteria already exist prior to the creation of an antibiotic drug. Antibiotic drugs works by targeting the structure of a bacteria's membrane protein or enzyme. Random mutations change the structure of some bacteria causing the drug to be ineffective. (This change occur before the antibiotic is ever used) The number of antibiotic resistance bacteria rise because all the bacteria that are not mutated are killed by the drug.

I 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? How could bacteria resist antibiotics if they can't "think"? After taking a college biology course, it turns out my suspicions were correct. I learned that biologist have a different idea of evolution than the lay person that claims to know what evolution is. Here are some excerpts from the textbook we used for this class:
"Because most species have become more complex over life’s long evolutionary history, many people erroneously believe that natural selection leads to ever more “perfect” organisms or that evolution works toward some long-term goal. Explanations that use the words need or in order to typically reflect this mis- conception. For example, a person might say, “The beaks in figure 11.8 grew because the finches needed to eat the large, tough seeds” or “The beaks grew in order to give the finches the ability to eat the largest seeds.”
Both explanations are incorrect because evolution does not have a goal. How could it? No known mechanism allows the environment to tell DNA how to mutate and generate the alleles needed to confront future conditions. Nor does natural selection strive for perfection; if it did, the vast majority of species in life’s history would still exist. Instead, most are extinct."
As you can see biologist do not believe organisms evolve to adapt to their environment. That is simply impossible. I've heard people on this site make that argument many times, it's not true. Another example:
A change in an organism’s DNA sequence introduces a new allele to a population. The new variant may be harmful, neutral, or beneficial, depending on how the mutation affects the sequence of the encoded protein.
Mutations are the raw material for evolution because genes contribute to phenotypes, and natural selection acts on phenotypes. For example, random mutations in bacterial DNA may change the shapes of key proteins in the cell’s ribosomes or cell wall. Exposure to antibiotics selects for some of the new phenotypes if they happen to make the cell resistant to the drug. In that case, the mutations will pass to the next generation.
A common misconception is that a mutation produces a novel adaptation precisely when a population “needs” it to confront a new environmental challenge. For example, many people mistakenly believe that antibiotics create resistance; that is, that resistance arises in bacteria in response to expo- sure to the drugs.
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 an- tibiotic resistance arises is if some bacteria happen to have a mutation that confers antibiotic resistance before exposure to the drug. The drug creates a situation in which these variants can flourish. That trait will then become more common within the population by natural selection. If no bacteria start out resistant, the drug kills the entire population. "
Bacterial resistance to antibiotics is the most used example as proof of evolution. As we can see however, bacteria cannot become resistance to antibiotics. At it's core evolution is random genetic mutations. There is no adaptation to environments, survival of the fittest, or bacterial resistance. The "evolution" taught by biologist makes a lot more sense as oppose to the fairy tale "evolution" that many people on this site and celeberties such as Dawkins believe in.

Would You Become A JW Again If Local Congregations Could Become Independent?
by Space Madness infor those who still believe in god, if local congregations could break away from the watchtower would you consider becoming a witness again.
this would mean no more governing body, circuit overseers, watchtower magazines, and each congregation could have its own "new light".
most of us left because of the control (no college, disfellowsipping) but if the watchtower was out of the picture, all of this would disappear.

The beliefs would be biblical only. No hell, no trinity, no immortal soul. There wouldn't be the watchtower teachings such as 1914, two Christian classes, no blood, no birthdays, etc. I'm surprise I'm the only person who feels this way.

It's Foolish to Believe the Watchtower Will Always Be Around.
by kneehighmiah inseptember 11, 2001. riding the bus to school that tuesday morning we discussed the implications of the monday night football game between the broncos and the dolphins.
by lunchtime our entire world have changed dramatically.
america had passed into a new era that would lead to major changes.

I just want to make a few corrections. Gay marriage is not recognized in most states and Obama is not black, he's half white. It's worth noting in most states where same sex marriage is recognized the citizens voted against it but judges forced the recognition of same sex marriage anyway. It'll be a long time before the majority of the united states' citizens accept same sex marriage and even longer before they elect a black president. With that said the Watchtower will be around when your great grandchildren retire.

Can White JWs Have Mustaches?
by Space Madness insomeone mentioned in another thread that white jws can't have mustaches but black jws can.
i noticed that the only governing body member with a mustache is black.
can anyone confirm that this is an official policy?

You people are nuts. She mentions a friend goes to the YMCA and you assume she is a troll? You think no JWs in the world go to the YMCA? I never heard of any type of restriction about going to the YMCA. The first time I heard of such a thing was after I left. The fact that this hasn't been mentioned in almost 40 years indicates that this rule is rarely enforced. I doubt most JWs even knew about that rule.
