Actually, it would be the perfect time. I've only read of the "destructive" nature of Bdellovibrio. Would the Bdelloplast in the example above then consist of an actually living E. coli? If you have something on hand that I can link to and read, that would be awesome.

I dove with a bp/w a couple of weeks ago for the first time and loved it. Does that mean I'm a candidate for heading to the "dark side?" I liked not having to wear much weight at all (6 lbs with a 5 mm wetsuit and aluminum bp), and I liked not having anything on my front. With that said...

You state that as a fact; I find that interesting. Isn't that the exact kind of thing that many have been arguing against on this thread...the stating as fact those items that are clearly speculation at best? So you're saying that your best example to support the endosymbiotic theory of...

http://myxo.css.msu.edu/lenski/pdf/2008,%20PNAS,%20Blount%20et%20al.pdf It's pretty clear on pages 7899 and 7900 of Lenski's inaugural PNAS paper that he is speaking of the same bacteria. In fact, on page 7900 of the paper, there is a reference (#31) to the paper where I got the information...

I don't get it! And why is this dang thing taking so long to load?

Hopefully the "flailing" divers will get better with experience. My high pressure hose is leaking too...time to get that taken care of, huh?

Or at least not making a move that is forbidden by God.

I agree. I guess that means that I am (1)Not a Christian, and (2)Possibly Jewish. Hmmmm...

Though you will probably get rebuked stiffly for: combining geological events with evolution and using Kent Hovind's name, the points about uniformitarianism and assumptions in measurements are well taken.

Again, I'm not ignoring anything. I've never had issues with the observational changes...except to say that the mechanisms don't produce the kinds of changes required of prokaryote to all life evolution. Granted. Granted. Of course you should know that would never be my argument...

Fine, define away. We shall see with further studies. Fine. The last paragraph on page 7904 of the PNAS paper, Lenski proposes two possibilities for the mechanism. One is that some already present "cryptic" transporter gene has been reactivated. Lenski deems this unlikely as the "Cit-...

The above was concerning my comment that if the mutants were placed back in natural environments they would get outcompeted. https://www.msu.edu/~lenski/ click on: –publications-complete list-acrobat file (for #180, the PNAS paper) First full paragraph on page 7904… “This stable...

Loss of functional specificity is not a genetic information increasing process. If a gene were changed into a completely different gene, that could possibly be novel, but would have come at the cost of the original gene. No, playing around with already present genes does not get a prokaryote...

Agreed, we must wait for further testing. It looks like we are going to have to define terms and context here. You are stating something novel was produced because it did not exist before (a transporter that no longer transports one item, but now two items, or some other mechanism...), and...

My only point was to show the difference between natural selection/genetic drift, and mutations. It seems pretty clear that natural selection and genetic drift can only "play around" with already present genes...typically genes are lost. Mutations would be the way that new genes are formed...

Genetic drift - Wikipedia, the free encyclopedia See first sentence. Genetic drift allows already present genes to "be carried forward," or can cause other already present genes to "disappear." No new genes are added by natural selection and genetic drift alone. Mutations would be the way...

They were obviously more fit for that environment; that is not in question. E. coli already possess the ability to utilize citrate so there was not the novel function introduced as proclaimed. I don't have access to the paper, but I hear tell that Lenski thinks that a different transporter...

Mechanisms Causing Rapid and Parallel Losses of Ribose Catabolism in Evolving Populations of Escherichia coli B -- Cooper et al. 183 (9): 2834 -- The Journal of Bacteriology The above stated that all 12 lines experienced various degrees of catabolic function decrease and that all 12 lines...

Yup. Except that E. coli already have the ability to utilize citrate when oxygen levels are low. There is a citrate transporter that allows citrate to be taken into the cell an used. In high levels of oxygen the transporter either does not work or is not produced. So the idea that Lenski's...

Cold.
