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."
Turds often float to the surface even in the genetic pool.

Okay... I was just saying
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.

Keep it up and it won't be a "just" a theory any more! I'm so sick of my neighbor saying "evolution is just a theory" with a scornful attitude that implies evolution is a whimsical idea kids will have and common sense will later dispel.
Anything you say will be held against you.
Ha! God let the devil do this so he can test who are the real faithful, and who are the unfaithful to be smitten.

We are not bacteria! We are not bacteria! We are not monkeys! I mean we are not bacteria!
You can't even see a bacteria with your own eye, so this can't be real.
Didn't the nylon eating bacteria already demonstrate that a complex trait can arise in short order? Actually I think it was industrial waste products from the nylon manufacturing process but still the same.
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 :)
Not at all! They'll just say, "That's micro evolution. Evolve me a giraffe in a petri dish and I'll be impressed."
It's funny how they are completely non-skeptical when it comes to their book, and how intensely skeptical they are toward things like evolution.

I've been watching bacteria developing complex evolutionary traits in my refrigerator for some time now....
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.
âoeTolerance applies only to persons, but never to truth. Intolerance applies only to truth, but never to persons.
Well of course. It doesn't even require them to change their position. The whole "micro-evolution versus macro-evolution" argument has always been about accepting that 1+1=2 while denying that 1 * 1000000 = 1000000 because it "hasn't been observed and can never be observed". Now that somebody managed to get to a million, they'll claim we have to count up to a billion to prove anything. Same argument, different scale.
I have seen the future, and it is inconvenient.
Spontaneous generation is a type of abiogenesis, but abiogenesis is not spontaneous generation. Abiogenesis refers to any theory about how life arose from non-life. Lookup abiogenesis on wikipedia for more.
That's because God wrote their book, and faith is the exact opposite of skepticism.
In a way you have to admire people with faith. They want so badly to be good people that they're willing to even discount things their own eyes show them, because seeing these things would break their faith.
It's amazing, really.
That's why no argument can ever be enough. It would screw up their relationship with God. They're understandably grouchy when scientists come up with stuff like this. It requires another round of mental gymnastics to keep their faith in order. Each round getting harder and harder to do as science keeps raising the bar.
Find some microbes on Mars, for instance. Watch what happens next.

rediculous.
Just ask a Creationist if they've seen an electron. When they try to explain how we can tell they exist from how they influence things that we can directly observe, they've just admitted that inference/indirect observation are in fact useful ways of gathering knowledge. At that point, their whole "you can't see it happening" nonsense evaporates. They'll likely fall back on epistemological nihilism at that point, but since that position trashes their beliefs just as thoroughly as science, I always take that as a tacit admission on their part that they're argument is utterly fucked.

I don't think the question should be "How does evolution fit within my God hypothesis?" I think the question should be, "What conclusion does my evolutionary data support?" The answer to that question may lead you to create a God hypothesis, which you would then invariably need to test more directly. However, looking at the situation from the perspective you described is like trying to decipher the revolution of the stars and planets about the Earth, because the Earth is in the center of the universe.

The Good News (for the world, not so much for you) is that by the time enough time has passed to prove such a thing, you will be dead. I cannot conceive of the horror if someone as stupid as you were to be immortal.
Or, maybe if the bacterium suddenly developed the ability to feed on their glass petri dishes.Right. If the bacterium does some new thing that there's really no reason for it to be able to do (lots of petri dishes are plastic now, BTW) then THAT will invalidate your belief? Of course not, because it would take a fucking miracle.
The simple truth is that as a rational individual it is safest to assume that any religious fundamentalist is wrong, because there are so many competing claims, and absolutely zero of them have been shown to have any grounding in reality. This is not the same thing as proving them wrong, of course. It's simply proving that there is no rational reason to believe them. If you choose to be irrational, that's your decision, but you shouldn't complain when people choose to label you as such.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
It must be rough for them, because speciation has been observed. Besides, not all Christians reject evolution. Don't equate your Fundie friends for all of Christianity. Biblical Literalism is a very new feature, and damned near any Church that still holds Augustine as any kind of theological figure does not advocate it.

This is an important result, and it's going to be more important when the mechanism by which it happened is figured out. Read the article.
The great thing here is that the researcher made a backup every 500 generations of bacteria, by freezing samples. So it's possible to go back and make this happen again and again, which has bee done. Then it's possible to find out exactly when it happened, and eventually decode the DNA before and after the evolutionary jump. This should produce some real insight into the underlying mechanism. We're a step closer to figuring out how evolution really works.
Humans made up god...
1, 2, 3, 4, 5... That's the combination on my luggage!
The interesting thing will be: why were e.Coli never able to metabolise citrate? Has new code been added to allow for citrate metabolisation, or was the mutation much smaller, maybe removing a blockage from existing but dormant code?
The press release is fascinating and infuriatingly incomplete at the same time.
Actually it sucks. Now the lime won't kill the bacteria on the beer bottle.
What?
I also believe that it is entirely possible that he did so by means of evolution.
My problem with this - by someone who claims to be a Christian - is this:
The Bible specifically says "And there was evening and there was morning, the Nth day." There are specific set spans of time spelled out in the Bible. And it specifically says "And God called out X and Y and Z and God formed Adam out of the dust of the ground", etc. It gives specific instances of God creating with His hands.
My problem is this: when you claim that evolution creeps in there, then the 24 hour days vanish. God no longer formed Adam out of the dust of the ground. If you believe the Bible to be truth, then you call God a liar.
But it doesn't stop there. So you don't believe the first 2 chapters of Genesis. Where do you stop? The fall into sin? The flood? The promised savior? By doing that you are calling the Bible a collection of stories, form which you can pick and choose. And that becomes dangerous.
**That** is my beef with Christians who compromise. I have no problem with people who choose not to believe in Christianity, that's their choice in life. I do have a problem with people who cherry-pick their beliefs within Christianity, or any religion for that matter.
(For the record, I do believe in a literal creation. I have no issue with micro evolution within species.)
Um, actually, that's been done. Yeast have been producing ethanol from sugar for how many years now? With very little modification, virtually none if you have a FFV, ethanol will work fine in your gas tank,... :-)
I'm so sick of my neighbor saying "evolution is just a theory" with a scornful attitude It will ALWAYS be a theory.
Just like the theory of electricity. No matter how many high-voltage cables we lay, the theory remains a theory.
You can't take the sky from me...
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.
"perplex and confound creationists"

In spite of what any of you say, I'm betting the resulting organism is a Escherichia coli bacterium. Wake me when it becomes a two celled organism
I am not interested in counterarguments, so I'll just repeat another old canard that works great in my church community and run away to safety.
First off, if you're putting a lime on your beer bottle, you're doing it wrong.
Secondly, if your opened beer bottle still contains beer over the course of the hours it takes for bacteria to colonize it (lime or no lime), you're doing it really wrong.
They don't believe that microbes become jellyfish, chickens become dinosaurs/dragons or apes become human [...]
Neither does the Theory of Evolution.
There is no difference between "microevolution" and "macroevolution" - except to people with agends, and those who don't know what they're talking about.
metabolize not synthesize ..........
enough mutation took place that this substance became a survival enhancing resource (or at least not a debilitating one in the environment)
Since we haven't had a good car analogy in this thread yet:
Microevolution would be if you drive your car across town. This has been proven so many times that by now everyone accepts it as true.
Macroevolution would be if you could drive your car all the way to another country. This is, as everyone in America knows, impossible.
Come to think of it, this analogy could help explain why they hardly ever have these kinds of debates in Europe, too...
If the masses can keep you down, you're not the Ubermensch.
No, they're not random. The Flying Spaghetti Monster reached out with His Noodly Appendage and blessed the bacteria. Ramen.
Your premises are incorrect. If it had evolved an ability to metabolize a substance that was not present, how would the scientists know? Also, natural selection merely states that those traits which give a reproductive advantage will spread. If the substance they become able to metabolize is not present, how does said ability provide a reproductive advantage?
If Intelligent Design were not so analogous to Military Intelligence, I might make the effort to click the link. Then again, my mind is not so open that my brain is in danger of falling out.
This isn't the first time we've seen evolution in the lab. Andrew Spiers has been doing it for years - e.g.
here (2003) or more recently here.
Basically Spiers grows bacteria in an unstired beaker. As the limiting resource for growth (nitrogen? Oxygen? I forget) is most available at the top of the beaker, it soon evolves a mutation which allows the bacteria to stick together and form a mat at the top ("wrinkly spreader"). Then somewhat later the mat collapses as freeloaders have evolved and come to dominate the population.
Spiers' experiment is highly predictable - the populations always go through the same phases, but different colonies turn out to have used different mutations to get there. This differs significantly from the research here, where it appears a low probability event has occured.

1.) That's not addressing the current paper. They talk of glycerol, and this paper is about citrate utilization.
2.) The logic in that ID response, to put it nicely, is full of excrement.
You're kidding, right?
Sailors knew the earth was spherical long before Jesus came along--it's obvious when you watch ships approaching over the horizon, since they're not only smaller but the bottom is hidden by the horizon.
Anyone who loves or hates any language, platform, or manufacturer, doesn't know what they're talking about.
If a soul exists, when does it come into being? At conception, formation of a brain, or...?
The reason I ask is because if it's at the formation of a brain, that would imply that the "meat" has importance independent of some immaterial artifact.
If it's at conception, what about identical twins where the zygote splits in two? Does the soul split in two as well? If what about when two young embryos (fraternal twins) merge to make a single embryo, a chimera? Do the two souls merge or does one simply go away?
If you look at the natural world in and of itself, these questions don't need to be asked. Zygotes sometimes split and young embryos sometimes merge. Done.
If however you fixate on the lessons of the Bible, you are stuck with an awkward sort of soul arithmetic; one soul divided by two equals two souls (or one half a soul), and one soul plus one soul equals one soul (or two souls in one body).
Citing Occam's Razor, which is more likely? That one zygote into two is simply that or that an immaterial and unproven concept known as a soul inhabits each of us and must under a special arithmetic to follow natural processes?

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."
Person B: There is no reason to believe in that unicorn. There is no evidence at all! You can't see, touch, smell, or hear him. He doesn't even give off heat, doesn't make noise, doesn't show up on any kind of instrumentation, etc. There is not even detectable mass! I'm guessing you're just making it up.
Person A: Well, I can't prove I'm right, and you can't prove I'm wrong, so I guess we're in the same spot! Since you don't know any more than me, why are you acting like you're more rational than me?
See what I'm getting at? You have completely turned critical thinking on its head. Believing in something for which there is no empirical evidence (by evidence, I don't mean that which is evident only after you have faith) is not on the same footing as skepticism. Saying that there is no tooth fairy is not a statement of faith.
What does sex in a boat and yankee beer have in common?

Ya gotta be pretty smart to live through being raised by them. Fortunately my mum was - hence me being here.
Funny story - although Grandpa walked around with club feet his whole life (praying that condition away apparently takes a very long time); something did happen that finally convinced them to see a doctor. My uncle (who was about 15 at the time) went from being irrational, to disturbed, to homicidal. I guess when you've got a homicidal 15 year old male in the house, and you can't out run him because your "please fix my damn club feet" prayer hasn't kicked in yet - self-interest makes you do crazy things - like call the nice men in the white coats. But as with many things, if you wait until something is life threating before changing your approach - it's usually a bit too late. No, he didn't kill my grandparents or anything - he got the typical "locked up and shocked up" treatment most people in his condition got back in the '50s. I don't know if Granpa asked if he was also too late to get his feet fixed, or just kinda figured it out on his own. The whole experience did cure them of their religion though.
Again, a bit late. The story losses it's "funny" status around the time my uncle escaped from the hospital. He burned down a block of flats for some reason, then later beat an old lady to death with a skillet because he thought she was trying to kill his children (he didn't actually have any children). Later he escaped from prison and showed up at my house with 2 other convicts, and car full of guns (no easy trick in England). My mum set them up and got them caught with no harm done to us (told ya she was smart).
So, to get back to the "Christian Scientists only hurt themselves" question - no, they don't. They can get other people killed at the same time. My uncle could have just as easily been afflicted with typhoid and sent off to school with nothing but prayer just as easily as he was sent into society with severe mental illness (which may or may not have been the result of some other untreated medical condition).
No one likes to take away something that makes people happy (like faith) - but until people take responsibility for their actions, it's the burden of others to deal with the mess. I think it's OK to argue that people should take responsibility for their actions - even if there's no way of doing it that won't offend them.
And while I don't want to see religious discrimination anymore than anyone else here does - I recognize that there's a world of difference between *offending* someone and discriminating or persecuting them. It's OK, when necessary, to offend.
