As a guess, I'd say it was worse here. (hope not)

          At least these "superbugs" were incinerated. So, I suppose your only option is to evolve faster than the bugs created by Monsanto and their ilk as they will be on your dinner table soon and into the future.

is behind it. Even farmers who raise chickens have to use the company's specifications on structure, cages, feed, drugs. They are employees of Monsanto, et al, even though they own the land and structures. And, being owners, if Monsanto(say) thinks it can make more money elsewhere, then the farmer is out of a job and stuck with useless structures which still might have money owed on them.

It is definately Monsanto and their ilk as you say.

Thanks for the diary.

          I get a huge amount of push-back when I point out the dangers of GMOs. Sure, GMO procedures produce an outcome that is much like the "natural" gene swapping, hybridization, and evolution extant and universal. But GMOs like corporate factory farming radically compress the time scale of the experiments.
          It's not just the changes that are important as it is the rate of changes and higher order effects that drive a dynamical system to chaos portending imminent collapse.

of GMOs but rather just add these: It has not been demonstrated that most widely planted GMO's have not been thoroughly tested in field conditions over a reasonable number of years. Gene insertion looks OK if you're coming from a reductionist theoretical background(and your paycheck depends on the GMO's success) but there have been many instances of GMO contamination of other crops, particularly those grown organically(or so I've been led to believe).

HGT is common in organisms without a nucleus, less common in organisms with a nucleus. There is no doubt that evolution proceeds, in part, on these genetic "swaps." Having fish DNA(say) incorporated into a plant is an impossibility under naturally occurring conditions and my vote is to disallow such experiements and products.

Thanks for focusing on an important topic and bringing an expert's view to it.

          Actually snippets of code from a fish are not necessarily unique to fish. While it may very well be impossible for a particular segment from a Salmon to become incorporated into a Corn plant, there is no reason to think it impossible for a Corn plant to develop that particular segment in its own genome over time.

if anything, an antifreeze gene?

Hey! my dear friends or soon-to-be's, JtC could use the donations to keep this site functioning for those of us who can still see the life preserver or flotsam in the water.

          What is well known is that the number of genes in a cell exceed the "necessary number" manyfold. Various coding mistakes occur over the life of an organism. (Please, notice the quotes around the words "necessary number" and don't hammer the "error" into the ground.)

          It is an interesting artifact that evolutionary processes are as slow as they are give this reality.

We got, like, ultra-antibiotics, basically life ending stuff. Sure, it may cause some super-cancer that may or may not be sentient, but with the mandatory pay-and-die healthcare system, you can rest assured that you will die penniless and your descendants will inherit your debt.

          The bacterium used was Escherichia coli. I doubt it was from some culture particularly selected for some obscure trait. An interesting aspect is the number of distinct cultures that evolved from the initial population.
          An really interesting followup would be to examine the DNA from the various spots to see if a geneticist post-hoc would produce the evolutionary tree seen in real time.

and no doubt a lab strain. Wild isolates would be expected to have resistance to some antibiotics, bacteria are slutty about transfer of resistance factors. As well, 11 days is long into the half-life of some antibiotics that age on hydration. That's all I was wondering, just supposin' at home. No biggie or exam!

          This highlights my ignorance very well:

as I was not aware of this complication.

          "no doubt a lab strain" was what I would expect if for no more of a reason than the attempt to impose uniformity on the large surface.

          Proving, once again, my lack of knowledge:

          As mitosis is the only reproductive path in this experiment I am unclear on a mechanism that would confer resistance so that progeny could invade the next levels of toxicity. Is it just bits of DNA being picked up from nearby cells bursting?

          I may be stupid but I ask questions like a five year old.

and that is a large (10e????) number of bacteria to start with. Look up mutation rates, assume 10e10 (just a wild-ass guess) bacteria to start.

Somehow it's a summation. If DNA repair is not fast enough, then mistakes are replicated.

          I was hoping for an additional channel. Just the usual suspects, Replication Errors cycling with Generational Count, creating new traits willy-nilly coupled to selection pressure. Too bad the process is so much slower with Meiosis and all that sex getting in the way. If not for that we could develop clear speciation demonstrations and shutdown the creationist's nonsense.

to see it visually. It's horrifying; all it needed was a John Carpenter score. In fact, let's give it one !

Creatures multiplying in the fog of human hubris: frankenfoods and resistant bacteria, to go with industrial pollution and nuclear waste.
