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."

    the bacteria suddenly acquired the ability to metabolise citrate, a second nutrient in their culture medium that E. coli normally cannot use. While I do agree that creationists will be perplexed and confounded, it will be due to the likely abysmal Biology and Chemistry programs in Alabama's educational system and not the actual implications of the study. I'm sorry but those results probably require too much extra explanation to really convince the type of person who think's evolution is just too hard to swaller.

    This is of course a fine strawman you have (barely) managed to tear down. "Godists" come in all stripes and colours, including those who have followed the development of evolution and agree with it, and those who do not.

    On the other hand, evolutionary biology, when misapplied to the social (pretend) sciences, produced a whole range of crimes against humanity whose shock waves have turned the Western mind inside out. But let's sweep those under the rug in favour of pointing out what a hypothetical group of people (who you invented) might do their hypothetical children (who you also invented).

  9. What a Crock by 9InchRails · · Score: 0, Troll

    A crack team of researchers make something happen, and the evolutionists clamor about how this is proof evolution exists! Pure crap. First of all, it didn't happen on it's own - the bacteria the had help of scientists. Sort of sounds like "intelligent design," if you ask me.

    Second of all, and much more importantly, anyone who espouses creation and has really read up on it, will allow for reproduction "within kinds." What that basically means is that you take a collie and a beagle, you get something somewhere in between, but it's still a dog, just like these bacteria are still bacteria.

    Furthermore, the creationist expects change. Breaking that down, God made a perfect creation, then something happened. On the spiritual side, sin entered in and brought death. The related physical manifestation is that the creation was corrupted by mutation. If the Universe is a closed system - as the evolutionist must conclude - then evolution violates the second law of thermodynamics, which states "The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium." This is exactly what the creationist believes - that the universe has been acted upon by outside forces and change happens inside - call it mutation.

    I wish everyone could be a lot less dogmatic. The truth of the matter is that neither creation nor evolution represent valid theories, because, claim what scientist might, neither is observable nor testable. Don't kid yourselves, folks, evolutionists have just as much faith in evolution as creationists do in creation.

    And you know what else, there's room enough for everyone to have a belief; don't be so righteously indignant, you insesitive clods!

  10. Does not prove cross-species evolution by JShadow · · Score: 0, Troll

    The article definitely proves that a species can evolve, but it does not prove they can evolve outside of their species or genus.

    The bacterium in question were still bacterium, they just weren't e.Coli anymore. At least not a strain we are familiar with.

    It's like the birds that Darwin observed in the Galapagos that had adapted to the kind of nut on the island. Sparrows on one island and long beaks while the sparrows on the other island had short beaks. Yet they had not ceased to be sparrows, but instead were very different sparrows.

    Making the leap from observing evolution of a species and saying that such evolution shows that a mole can give rise to a whale is quite a leap indeed. Perhaps that's what they mean by "leap of faith"? :)

    This study is definitely interesting, and will be even more so when they actually finish it and find what changed genetically and why.

  11. Now you can call it science... by gillbates · · Score: 0, Troll

    Okay, *now* scientists can claim evolution is science, now that they've seen it in the lab. However, prior to this, evolution was just a theory, and quite possibly, a religious belief to the science-faithful.

    All of you who believed in evolution prior to this belong in the same camp with the religious wingnuts: you both believed in something which hadn't been proven at the time.

    But some of you, myself included, were waiting for proof of evolution before we believed it to be true. It's not that I doubted, but rather, believe that in the interests of science, and the scientific method, it is generally best to avoid believing something until proof exists. Those of you who believed before proof did so on faith alone, which - surprise! - gives you more in common with the creationists than you would like to admit.

    This is how science is supposed to work, folks. Faith has no place in science - leave that for religion. Does it surprise anyone that arguments about tenets of faith go nowhere? Instead, concentrate on what can be proven.

    To use a more contemporary analogy, if I teach someone how to drive a car and he uses that knowledge to deliberately run people over, it isn't my fault; it's his.
    And here in lies the problem with most Theistic religious, its the perfect way to avoid taking responsibility, the "divine forgiveness" clause. This states that no matter what you have done so long as you are a good $THEIST and repent God will forgive you. Also with Theists God is the only one who can judge them thus they are never required to take responsibility for their own actions.

    This is the biggest reason that there is a higher proportion of religious people in prisons, it allows people to escape responsibility for their crimes (and in so doing escape punishment). Whilst a lot of criminals convert to a Theistic religion in prison (to escape punishment and get a reduced sentance) many of them were devoutly religious to begin with. A non Theistic or non devout believer is far more likely to ask themselves weather they could live with the harm they are about to cause whilst a religious criminal is more likely to commit a crime without a second thought as they believe that what they are doing is alright with God and that only God can judge them. Many of our worst serial criminals (Think along the lines of David Berkowitz) were quiet religious.

    ....the new evolution which they claim....

    Of course occurred entirely at random, out in the wilds of nature someplace, without the involvement of intelligent scientists working diligently in their lab. Were there new bacteria or did the same old bacteria just exhibit an already inherent ability to use a different source of nutrition? Is it possible to discern that this "newly found" ability of these bacteria to thrive on a different nutrient was NOT already latent in the original ones they started with?

    The newly skilled bacteria are still e-coli and not some other species, such as coccus or spirochete. So therefore, as usual, this is not a case of macro-evolution at all, but as always, only another example of the amazing adaptability of living things. Applying the word "evolution" to such adaptation doesn't justify the leap to claiming that birds came from reptiles or monkeys are the ancestors of people.

    They would also likely accept that intelligent scientists are able to do things that don't happen randomly in nature. Here some intelligent scientists DESIGNED an experiment and found that bacteria can adapt to using some other nutrients than what they were used to, before the scientists manipulated the nutrient source. Boy, what a monumental discovery! These e-coli bacteria were STILl e-coli bacteria and will forever remain e-coli bacteria, even though under duress from the experiment, expressed their innate ability to thrive on some other nutrients.

    ....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....

    The driving force for evolution is driven by the the so-called survival of the fittest mechanism. How would the ability to stand upright give a consistent survival advantage to monkeys who gradually stood upright over a time span of millions of years or even only 500,000 years? Being taller might give them an advantage in reaching higher hanging fruit or other sources of food, but also make them more visible to their enemies. Monkeys that get eaten because they are more visible certainly don't have an advantage. In their presumed environment, being taller is at best, a wash. It is certainly not a distinct, decisive survival advantage to be taller.

    Even after in this case 35,000 generations, these bacteria were still E. coli and nothing more. They did not evolve into another species of bacteria, let alone an entirely different organism. They were still the same, essentially unchanged life form they had always been. If anything, the experiment shows, that even after a 35,000 generations, the change is still well within the definition of a single species.

    Being able to utilize a slightly different food source is nothing more than evidence for the amazing adaptability of all living things.

    ....Because not having this ability....

    How is it possible to tell that these bacteria did not have this ability all along, rather than expressing it at some point due to the extended pressure of the changed environment? Being able to utilize a different food source is nothing more than an adaptation.

    Most of us do not normally eat worms, snails, insects, frogs and other creatures. However, people that have been lost in the wilderness have survived on such and other things. As populations have migrated to other regions of the earth, where their food sources have changed, but they have not evolved into some other species because that.

    These bacteria were E. coli before and after the experiment and they will always be E. coli no matter what is done to them or how their abilities to utilize various substances is changed. Even after 35,000 generations, they did not evolve into a new species. This experiment is no proof of evolution.

    The bacteria in this experiment, were placed into an environment that eventually forced them to digest substances that could still sustain their life. They did not become a new species or kind, but remained exactly as they had always been. Once an E. coli always an E. coli, once a worm, always a worm, once a person, always a person. That is all we consistently observe occurring in nature. You just cannot get around it because that is how things are.
