Bacteria Make Major Evolutionary Shift In the Lab
Auxbuss sends us to New Scientist for news sure to perplex and confound creationists: scientists have watched a new, complex evolutionary trait develop in the lab. "A major evolutionary innovation has unfurled right in front of researchers' eyes. It's the first time evolution has been caught in the act of making such a rare and complex new trait. And because the species in question is a bacterium, scientists have been able to replay history to show how this evolutionary novelty grew from the accumulation of unpredictable, chance events."

Continuous creation. God put those new bacteria there to test my faith ;-)

It's a miracle!

"One in a billion odds" means very, very different things for bacteria than it does for humans.
Wasn't that already proven with the rise of homo sapiens?

This is why doctors ask people to finish the entire bottle when prescribing antibiotics. This is also why we should ban antibacterial hand soaps for domestic use - because when you bathe a population of microbes in something for millions of generations, the odds are that eventually a spontaneous mutation will occur.
All the anal-retentive clean freaks will just have to figure out how to live with the notion that they - like everyone else - carry microbes on their skin.

You could counter your neighbour with "gravity is 'just a theory'" as well.
No, it'll still just be a theory. A theory that happens to match reality with a large pile of evidence behind it. But in science, there's really no such thing as a "fact", simply theories with greater levels of evidence supporting them.
Gravity is just a theory. The Sun-centered solar system is just a theory. Radio waves are just a theory.
E pluribus unum
For those of you who didn't RTFA, the new evolution which they claim occurred was the ability to metabolize citrate, a substance in the culture medium that e. coli were previously known to be unable to metabolize, and this occurred in one of twelve populations that were spawned from a single parent bacterium. I think it's pretty interesting :)
Anyway, it's an interesting find, but I wonder, why did they not wait until they finished their investigation of the event? It says that they're still figuring out if the change was a random, incredibly rare mutation, or the result of many small changes. Why not wait until you get the whole story to announce your discovery?

I often find it amazing how people are stereotyped. Not all people who believe God is responsible for creation of the universe have a problem with evolutionary theory. Roman Catholics believe God is responsible for everything. Including random chance ( which everyone knows is seldom all the random.)
So assuming all science were in and we could prove from end to end the entire evolution of the human species , you would have made no progress in proving or disproving either the existence of God or weather or not He was ultimately responsible for the creation of human beings.
The only group that holds 'evolution can't happen because the bible says' is a very small minority of Christians. Specifically biblical literalists.
Evolution also poses no particular threat to Hindu or Buddhist belief system.

Actually it sucks. Now the lime won't kill the bacteria on the beer bottle.
What?
Second, this argument is terrible.
Why would life not form? Because the laws of nature say so? But we just established the laws of nature are not the same in this alternate universe. Its a variation on the first fallacy. "Life" has the characteristics of this universe because it exists in this universe. If there was another set of rules, life might be much more likely, much less likely, extremely different or very similar.
Ok, I'll bite, given that this is the third post of yours that I've seen adamantly opposing this as proof of evolution.
Yes, it is. First, RTFA, please. If you already did, I ask that you read it again with an open mind because I think you'll see that you missed something. You have continually asserted that maybe they always possessed this ability, but never expressed it until they needed to. However, in the experiment, somewhere around generation 20,000 is when this was enabled. Bacterial lines before generation 20,000 do not develop the gene, but lineages derived from that set do when "replayed." This, along with the fact that none of the other lines of bacteria show it under the same conditions (despite all originating in the same place) shows that this was not simply a case of a dormant gene becoming active. Only bacteria after a certain point in a certain genetic line were able to perform this function. That is adaptation and evolution since it outcompeted the other bacteria which lacked the trait.
Sure it does. Give me one good reason why over the course of generations genes in monkeys couldn't slowly be mutated to stand upright and gain benefits from it. Remember, these bacteria took 35,000 generations to achieve this minor mutation. If we assume that the monkeys had 15 year generations (which I believe is quite long, maybe someone else can chime in who knows more on primate generational times), that is 500,000 years to make 35,000 generations for this beneficial mutation. Current science and anthropology think spines straightened over the course of millions of years, which means that it took even longer. It really is no leap. It just takes longer time scales and more generations than you seem to be able to comprehend (and most of us can't) at one time.
I think you ought to rethink your concept of "evolution" to mean more of the generation of random traits through mutation where beneficial results sometimes arise. Sometimes cancer or miscarriage results, and sometimes it's the difference between blue and brown eyes. But what you need to keep in mind is that all of these complex adaptations are not one single mutation. They are chained mutations that just happened to be beneficial with numerous, uncountable numbers of failures (eg:miscarriages and pre-reproductive deaths) over generational timescales. Your eyes didn't develop from one mutation. Nor did the lens in your eye or even the membrane on the lens. It is all the result of MANY mutations. That's why it's reasonable to make the "leap."
