Evolution cannot be proven by the scientific method and therefore it is not real science.
Evolution has been proven. This is why there are anti-biotic resistant forms of bacteria today that did not exist 50 years ago, or even in some cases 1 year ago.
Futile it is
What scientific experiment was performed proving that a living cell can form spontaneously form inanimate stuff? The answer is none.
Not science. Variation is everywhere and does not need to be proven.

not only that, but the bacteria are STILL bacteria.
they didn't evolve at all.
a particularly important adaptation that occurred in the population called Ara-3: the bacteria evolved the ability to grow on citrate under the oxygen-rich conditions of the experiment. Wild-type E. coli cannot grow on citrate when oxygen is present due to the inability during aerobic metabolism to produce an appropriate transporter protein that can bring citrate into the cell, where it could be metabolized via the citric acid cycle. The consequent lack of growth on citrate under oxic conditions, referred to as a Cit- phenotype, is considered a defining characteristic of the species that has been a valuable means of differentiating E. coli from pathogenic Salmonella.
The mean fitness of each population, as measured against the ancestor strain, increased, rapidly at first, but leveled off after close to 20,000 generations (at which point they grew about 70% faster than the ancestor strain). All populations evolved larger cell volumes and lower maximum population densities, and all became specialized for living on glucose (with declines in fitness relative to the ancestor strain when grown in dissimilar nutrients). Of the 12 populations, four developed defects in their ability to repair DNA, greatly increasing the rate of additional mutations in those strains.
they adapted. if they grew wings, i'd be impressed.
people live through plagues/flu without any medicine. big deal.
they are still human.

I'm seeing an issue here and it brings up another I guess...
People are throwing out science for the bible. Evolution is a valid theory, just like the theory of gravity. It's that solid. Man Made Global Warming is a valid theory, just like the theory of gravity. It's that solid. Every medical/psychiatric or psychological society, organization or group states that this treatment is bad and that there is nothing wrong with homosexuality...ergo it's not a mental illness.
Why do you guys go against science on everything?

Abiogenesis has nothing to do with evolution.
do you think a bunch of crap turning into life is not evolution?

They didn't? Interesting way of viewing what has happened to the original 12 E. coli populations over the course of 60,000 generations. One of the strains evolved to subsist off of an entirely new food source

If that's not good evidence for evolution, and that's just one offspring somewhere around 30,000 generations of the original 12, I just don't know what is. Misunderstanding the mechanisms of evolution is not the same as evolution not occurring. Adaptation is a huge part of natural selection which is most certainly one of the mechanisms that drive evolution.
Also, to say its not evolution because its still bacteria is just silly. Humans now and humans 50,000 years ago are both human but there are genetic and anatomical differences because evolution is a slow and on going process.

Me too, but mostly because that isn't how evolution works so we would have to rethink the paradigm if something like that occurred.

Right, because evolution just happens over the course of a generation or two...
Just because surviving a pandemic doesn't turn you into one of the X-Men doesn't mean the survivors aren't going to pass those genes that allowed for their genetic fitness, on down to their offspring who will in turn pass those genes on to their offspring and on and on. Sometimes these genes become prevalent in the general population, sometimes the diseases adapt faster than we do. Whether you want to admit it or not, adaptation is an important part of natural selection which IS a mechanism of evolution. The same statement applies to the Lenski experiment. You can't say 'well its not evolution, its just adaptation.' The two are often bosom buddies.
Since there are many ex gays we cannot just pretend there is no chance that any gay will benefit from treatment.

If your neighbor is drinking himself to death are you showing more love by trying to convince him to stop or telling him he is perfect the way he is?
Your insult that I cannot manage to not hate, actually shows your hatred.
