But it's all in the genes, so it would appear.
http://www.sciencedaily.com/releases/2009/06/090617131400.htm
From the authors of the research:-
Mitchell, A. et al. (2009) Adaptive prediction of environmental changes by microorganisms. Nature, advance online.
Natural habitats of some microorganisms may fluctuate erratically, whereas others, which are more predictable, offer the opportunity to prepare in advance for the next environmental change. In analogy to classical Pavlovian conditioning, microorganisms may have evolved to anticipate environmental stimuli by adapting to their temporal order of appearance. Here we present evidence for environmental change anticipation in two model microorganisms, Escherichia coli and Saccharomyces cerevisiae. We show that anticipation is an adaptive trait, because pre-exposure to the stimulus that typically appears early in the ecology improves the organism's fitness when encountered with a second stimulus. Additionally, we observe loss of the conditioned response in E. coli strains that were repeatedly exposed in a laboratory evolution experiment only to the first stimulus. Focusing on the molecular level reveals that the natural temporal order of stimuli is embedded in the wiring of the regulatory network—early stimuli pre-induce genes that would be needed for later ones, yet later stimuli only induce genes needed to cope with them. Our work indicates that environmental anticipation is an adaptive trait that was repeatedly selected for during evolution and thus may be ubiquitous in biology.”

For God's sake, Roland, when are you going to give up on the idea that evolution has any kind of intelligence behind it? You can only stretch even the most flexible of rubber bands so far before it goes snap.
Nevertheless, I'm sure these windbags really do believe the nonsense they're making up as they go along.

You go first Sporty. Explain how come, if atoms are intelligent, that iron bars are dumb.
I shall be over at CARM shortly to see if there is any more progress from other YECs on:-
1) All fish that leave the water must die, even though it is observed that some fish can leave the water and not die, and
2) "God did it" is a very good explanation for anything because it is a) rational, b) clear, and c) parsimonious.
I just need a few bottles of whisky before hand, just to get my mind in order to think creation science through.

Problem is Jorge, they are, in essence, YEC arguments over at CARM.
The intelligent atoms one belongs to Sporty.
The fish one belongs to another bloke who claims that tetrapods cannot have evolved from fish because as soon as any fish leaves water, it begins to die. You will understand what happened next. After several exchanges with me pointing out that many fish leave the water for periods of time and then return to it, he simply stood on his dig, told me that I was trying to trap him, and that I was simply wrong, so there. A post or two later he put me on ignore. (Ring a bell Jorge?)
The "God did" it is the essence of an exchange I am having with another poster who claimed that the Biblical account of creation is much better than any Aztec one for essentially the reasons I gave. Problem is, he forgot to tell me how he managed to reach these conclusions. He still hasn't told me. But what time he does give me is spent avoiding this kind of issue. (Is that another bell I hear going "ding", "ding"?)
Jorge, I cannot help it if the above examples are what creation science leads you guys to accept. And surely you would understand why several bottles of whisky are needed in order for one to think like so many of you do.

I challenge you to prove otherwise; i.e., that as soon as a fish leaves the
water it does not begin to die. I know about lungfish, etc. While these
may survive outside of water, it's just survival - they neither feed nor
reproduce. Besides, it's only for a limited period of time. You will never
find a lungfish or any other fish born and / or living permanently on dry land.
Thus, this "bloke" is absolutely correct.
It is by FAITH that you believe in a fish-to-tetrapod evolution ... zero evidence.

Hello Jorge. You say:

That sounds like a pretty definitive statement to me. As you are so confident in your opinion, why don't you pop over here:
http://talkrational.org/forumdisplay.php?f=23
where you will find Per Ahlberg. Per is a world leading palaeontologist and a specialist in tetrapod evolution. Since you seem so certain that his entire career has been a waste of time and there is no basis whatsoever for any of the multitude of papers he has written, it would only seem fair to let him know.
In addition, you could chat to Martin Brazeau, one of Per's former PhD students and an increasingly prominent palaeontologist in his own right. He has also published evidence for tetrapod evolution. So that's an extra incentive for you.
Here are just a few of their most recent papers, to give you a flavour:

I look forward to you putting your money where your mouth is.
No, let me give you a "flavor".
The total number of links that you provided were 6. So I did my
labeling thing, tossed a die, and the one by Boisvert came out.
Here's the abstract with a few comments inserted (perhaps this will give you a clue) :
One of the identifying characteristics of tetrapods (limbed vertebrates) is the presence of fingers and toes. That's a valid observation. Whereas the proximal part of the tetrapod limb skeleton can easily be homologized with the paired fin skeletons of sarcopterygian (lobe-finned) fish, That's NOT an observation; that's making the data fit the theory. there has been much debate about the origin of digits. Early hypotheses1 (http://www.nature.com/nature/journal/v456/n7222/full/nature07339.html#B1) interpreted digits as derivatives of fin radials, but during the 1990s the idea gained acceptance that digits are evolutionary novelties without direct equivalents in fish fin skeletons. Again, this is not an observation; this is thinking as per the evolutionary presupposition. This was partly based on developmental genetic data2 (http://www.nature.com/nature/journal/v456/n7222/full/nature07339.html#B2), but also substantially on the pectoral fin skeleton of the elpistostegid (transitional fish/tetrapod) Panderichthys, which appeared to lack distal digit-like radials3 (http://www.nature.com/nature/journal/v456/n7222/full/nature07339.html#B3). DITTO. Here we present a CT scan study of an undisturbed pectoral fin of Panderichthys demonstrating that the plate-like 'ulnare' of previous reconstructions is an artefact and that distal radials are in fact present. This distal portion is more tetrapod-like than that found in Tiktaalik4 (http://www.nature.com/nature/journal/v456/n7222/full/nature07339.html#B4) and, in combination with new data about fin development in basal actinopterygians5 (http://www.nature.com/nature/journal/v456/n7222/full/nature07339.html#B5), sharks6 (http://www.nature.com/nature/journal/v456/n7222/full/nature07339.html#B6) and lungfish7 (http://www.nature.com/nature/journal/v456/n7222/full/nature07339.html#B7), makes a strong case for fingers not being a novelty of tetrapods but derived from pre-existing distal radials present in all sarcopterygian fish. Three words : interpretation, interpretation, interpretation. Here's how it goes : first, evolution is true - period. Then, whatever is observed must be acccording to evolution (since it is a fact, Fact, FACT!). Ergo, the new data is interpreted as suggesting that fingers weren't a novelty of tetrapods but derived from pre-existing distal radials present in sarcopterygian fish. That, then, becomes "science" that is publishable in a leading "scientific" journal, Nature, and is based on hypotheses built upon hypotheses built upon hypotheses.

I challenge you to prove otherwise; i.e., that as soon as a fish leaves the
water it does not begin to die. I know about lungfish, etc. While these
may survive outside of water, it's just survival - they neither feed nor
reproduce. Besides, it's only for a limited period of time. You will never
find a lungfish or any other fish born and / or living permanently on dry land.
Thus, this "bloke" is absolutely correct.

Jorge - you contradict yourself in your second sentence. Your third sentence is a back-peddle and ignores the fact that in a hypothetical transition from fish to land animal, per ToE, at some period in time along the path of evolving from a fish to a tetrapod, a creature capable of doing both would exist ... which is what you just described.
And so it is clear a creature can exist that can do both that is fish-like.
As for the first sentence - any hypothetical path of evolution would propose that some natural environmental element would select for fish that can survive longer outside of water. The initial fish in the transition doesn't have to be able to live on land, there only need be some natural advantage to being able to be out of the water for periods of time to drive, over time, a gradually increasing capability to be out of the water.
As for zero evidence - that is simply false. We have a clear set of fossils consistent with the hypothesis fish evolved into tetrapods. What you really mean is something more along the lines of there is no existing evidence that could convince YOU of fish to tetrapod evolution.

Really Jorge? I’ve seen mudskipper’s eating crickets before and the mudskippers had to leave the pond they were in to get them. In fact, this from Wikipedia:
They are completely amphibious fish, fish that can use its pectoral fins to "walk" on land. Being amphibious, they are uniquely adapted to intertidal habitats, unlike most fish in such habitats which survive the retreat of the tide by hiding under wet seaweed or in tidal pools. Mudskippers are quite active when out of water, feeding and interacting with one another, for example to defend their territories.
Source (http://en.wikipedia.org/wiki/Mudskipper)
Sounds like they, being “completely amphibious fish,” are able to do quite a bit more than just survive when they’re out of water.
In fact, HERE (http://www.youtube.com/watch?v=N-T_pu-ImVU&feature=related) is a 15 second video of baby mudskippers being hand fed while they’re out of the water (there are numerous videos that show mudskippers hunting prey as well).
It is by FAITH that you believe in a fish-to-tetrapod evolution ... zero evidence.
Those pesky fossils of "fishapods" such as Tiktaalik notwithstanding.

… I am willing to bet good money that you are
misunderstanding the argument.
Then tell me about it Jorge. Oh wait …
Without even looking …
… you don’t want to examine it to see.
I challenge you to prove otherwise;
Well I was hoping he would prove his point. But he didn’t. Like I said, he simply did a Jorge, stood on his dig, declared himself to be correct and put me on ignore. The argument got so silly that he wrote:-
“;ergo evolution of the fish to amphibian kind cannot happen because every fish that came out of the water (his natural habitat) starts dying because he cannot breath the way he was created to do.”
And later:-
” Not in the sense of lungs. And not in the sense of living a productive life, gathering/catching food, reproducing. So I restate my observed position:- Fish out of water, Fish Dies – EVERY TIME. “
As one commentator noted:-
”Note well boys and girls, He is now claiming to have observed every fish that ever came out of water for the last many millions of years. This seems a bit of a stretch. Come on buddy, you have to have missed a few of them, and those are the ones that did not die, indeed the ones that gave rise to you and yours eventually!”
As I noted
” So since every fish dies every time, then how come mudskippers and lungfish manage to make it back? I mean, mudskippers do make it back to the water don't they Sheph? Yet you claim they die. How does this all work. A fish crawls out of the water, lives, does it thing, crawls back.”
i.e., that as soon as a fish leaves the water it does not begin to die. I know about lungfish, etc. While these may survive outside of water, it's just survival - they neither feed nor reproduce. Besides, it's only for a limited period of time. You will never find a lungfish or any other fish born and / or living permanently on dry land. Thus, this "bloke" is absolutely correct.
You never did understand the theory you spend so much time criticizing did you Jorge. You really are a case of “choice trumps knowledge”.
Here is something from another poster:-
Nice try sheppie. Read the following about the Mangrove Killfish, which can live indefinitely out of water:
http://www.aboutmyplanet.com/environment/living/
It is a fish. And it doesn't die when it leaves the water. For months at a time. Not all, or even most fish are adapted to live out of the water. But some are. It's observable. All it would take is one type of fish (like the above) to survive on land for extended periods and then its descendants gradually adapt to a largely terrestial lifestyle.
Kind of like amphibians, wouldn't you say? Most amphibians need to keep their skin moist, and have to return to the water to reproduce. Not unlike the Mangrove Killfish, which is STILL A FISH. Or would you consider it to be of the amphibifish kind?
So nice try Jorge. Did you note what the article said?????
People like me aren't avoiding the issue , we are avoiding YOU (invincible ignorance).
Is it because of my lack of under-arm deodorant? Because I don’t shower?
People drink whiskey, tequila, vodka, whatever to avoid facing certain truths. You may put whatever twist you wish on that.
But it’s true Jorge. It must be, because I said so.
You go on right ahead and continue trying to justify your beliefs however way you think you can get away with, …

66 days! The fish usually lives in water with low oxygen content. Mud-bottomed ditches,
marshes, and even in heavily polluted salt and fresh water. When these areas dry up, they
move into local logs until more water areas become available."

You are a very dishonest debater, rogue06 and (from the other posts) you are not alone.
Clearly, except to the brain-dead or the dishonest, my comment about infallibility / worthy

"Per is a world leading palaeontologist and a specialist in tetrapod evolution ... In addition,

prominent palaeontologist in his own right. He has also published evidence for tetrapod

I've said this before : everything needs to be spelled out for you people (the whole lot of you).
Either you are mentally deficient or you ignore the obvious so as to justify acts of vilification.
I do not give a rat's tail about Per's or Brazeau's credentials. They have subscribed to a
BELIEF system and they promote this system at every turn. They base all of their work on
the presupposition that things happened this way and the data are made to fit this system.
If the data deviates in any way then they concoct auxiliary hypotheses that make the data
fit with the evolutionary model. That you cannot / will not comprehend this is your problem.

Er Jorge...indefinitely means having no exact limits. The longest sample was 66 days. The point being to counteract the creto claim that the fish would die within hours of leaving the water.

Ya know Jorge, instead of just running that big mouth you could go to TalkRational (http://www.talkrational.org/) and address Per and Martin directly. They've both been extremely pleasant and more than willing to explain their work.

Yup, I sure did note what it said! Apparently you did not.
In bolded red letters, you / Birdam claim that this fish can live "indefinitely out of the water".
The article says, "After his studies, he found that the fish can actively survive out of water for
66 days! The fish usually lives in water with low oxygen content. Mud-bottomed ditches,
marshes, and even in heavily polluted salt and fresh water. When these areas dry up, they
move into local logs until more water areas become available."
At the school that I went to, 66 days is NOT "indefinitely".
Why don't you try again, Roland, after you sober up?
Jorge
How about your claim that "they neither feed nor reproduce" out of water which was terminally rebutted by the fact that mudskippers most certainly do hunt and feed while out of water?

This is a lie. Rogue06 is not a 'dishonest debator'. He (almost?) never even lowers himself to the kinds of underhanded tactics you yourself use, and he ALWAYS deals with the actual data at hand, something you only occasionally (and rather poorly) attempt to do.
Clearly, except to the brain-dead or the dishonest, my comment about infallibility / worthy

See - lots of name calling, lots of ad-homenem accusations - but does Jorge ever get to the data on mudskippers in Rogue's post?
"Per is a world leading palaeontologist and a specialist in tetrapod evolution ... In addition,

Ah - another set of accusations without substantiation.
So Jorge, do you care to point out where the data leads away from fish -> tetrapod evolution and exactly how that data is being ignored or explained away?

If the mudskipper is in or out of the water and a convenient snack happens to
present itself, they try to gobble it up. That, however, wasn't the point.
ALL fish - mudskippers, Mangrove Killfishes, etc. - are fishes because out of
or without water they are D-E-A-D in relatively little time. Mudskippers, e.g.,
have the ability to breathe through their skin and the lining of their mouth and
pharynx but only when the mudskipper is wet, limiting mudskippers to humid
habitats and requiring that they keep themselves moist. This mode of breathing,
similar to that employed by amphibians, is known as cutaneous air breathing.
The point that in typical, sophomoric fashion you people were here attacking was the

Your ability to desperately look up wikipedia and then copy stuff in an attempt to make yourself sound vaguely knowledgable, is hugely impressive. From wiki (http://en.wikipedia.org/wiki/Mudskipper) (coloured to show the C&P):
The ability to breathe through their skin and the lining of their mouth (the mucosa) and throat (the pharynx).

Sorry Jorge, you very clearly asserted that "they neither feed nor reproduce" when they are out of the water which has been shown to be false. If you want to shift the goal posts that's your business but it has been duly noted.

The point that in typical, sophomoric fashion you people were here attacking was the
claim "Fish out of water, Fish Dies – EVERY TIME."
The fish aren’t exactly immortal in the water either Jorge. IOW, “Fish in water, Fish Dies – EVERY TIME.” In fact, I think it’s safe to say that without water you would die in relatively short order (I wonder if you could last 66 days). And if you hadn’t noticed nobody has claimed that lungfish, mudskippers and the like are amphibians though they may be amphibious. And speaking of amphibians, IIRC, they generally don’t do well away from water for long periods of time either. Have they “subscribed to BELIEF system” as well? Are they part of the Grand “Evilutionist” Conspiracy (GEC)?
[/I]That claim is true except by FAITH,
namely, that 'sometime umpteen million years ago a fish permanently came out of the
water and did not die'.
Sorry, I’m getting images of some ancient “Methuselah fish” refusing to die even after all theses eons.

Is that all you have to say Jorge?
You reckon that all fish begin to die as soon as they leave the water.
I point you to one fish clocked at 66 days out of water, and you quip that the poster I copied it from, used the word "indefinitely"?

Getting back to bacteria...
This morning I got an update from the BBC Canada Shop, advertising their magazine Knowledge. You can click on a free online sample issue (March/April, 2009). One of the articles is entitled “Evolution in Action”.
It is fascinating. Some of you will already be aware of Richard Lenski’s 21-year experiment with E. coli bacteria, but this 4 page article is written in language I can understand with ease. [I appreciate that!] You can get it here: http://www.nxtbook.com/nxteu/BBC/knowledge_200904v2/#/48
Briefly, Lenski subjected the bacteria to “famine” conditions, to see if and how they would adapt. He kept them in a standard laboratory broth, but with only a “meagre supply of glucose”.
E. coli need iron, but can’t take in free iron atoms; so citrate is part of the broth. It binds with the iron in such a way that the bacteria can absorb it. But the bacteria do not use the citrate as FOOD.
By the end of 31,000 generations [from 1988 to 2001), one of the twelve lines of bacteria were using the citrate as a source of food. By the end of 45,000 generations (2008), all of the bacteria were growing 75% faster than their “ancestors” 20 years earlier. They had adapted to the new conditions.
This, it seems to me, is just one more confirmation that Darwin’s special theory of evolution was accurate.
It does nothing at all towards proving Darwin’s GENERAL theory. In fact, if you think about it, it seems to do just the opposite.

Instead try to make eye contact. And be sure to tip (over 10% cheapskate) or be prepared to be ignored afterward. I've found being 6'4" makes it easy to get noticed as well - especially with the women bartenders
No tipping in British bars. The beer already costs enough.

Gotcha.
Ouch.
I'm ashamed to ask, but what does IIRC mean?IIRC = If I Remember Correctly.
IOW = In Other Words.
AFAICT = As Far As I Can Tell.
AFAIK = As Far As I Know
AFAIAC = As Far As I Am Concerned.
My Net vocabulary runs out after this.

Thank you. It's nice to be able to recognize some Net vocabulary, though I'll probably stick with the Gross stuff myself. At my age, it's hard to learn a new language.
Forget the "Ouch". I just meant I understand what you're saying. I think. Possibly.

Has anyone read this from behavioral/brain sciences? It isn't about bacteria - maybe the other end of the scale.

I am beginning to find all this out myself. :teeth:

This is a bit like the new field of evolutionary psychology. Every one seems to have an opinion and can argue their case well. In the end, I throw up my hands and become inclinded to wait for a bit, until the dust settles.
The problem in this particular case (as with evolutionary psychology, as with the argument between dualism and monism (?) with respect to the mind) is that we are dealing with the mind and consciousness. And that is very murky territory indeed. While a materialist myself, (i.e. mind is the product of particular arrangements of matter, if I can put it so crudely), I enjoy listening to both sides of the argument and when trying to formulate a reasonable opinion, end up arguing with myself. (So far I haven't lost an argument yet. But I haven't won one either.)
For these reasons, I tend to feel happier with good old material genes and how they change over time.

How very, very sad ...
You people are so desperate to vilify me that you'll latch on to just about anything?
To wit : here you wish to accuse me of plagiarism.
Now take a look at essentially EVERY post that I have ever written here at TWeb
where I use material from some source. What do you see? That's right -
essentially EVERY time I use a different color font - typically green or dark red -
to denote that it comes from a source. True, I did not mention the source here
but given the source and the information used it did not seem that important.
Errr .... not important except to people desperately seeking some technicality
so as to finally 'win' one over on Jorge. You people are pathetic beyond words.
Is such pitiful trivia the best you can come up with?
I need at least a few days' break from you people. :no:
Jorge
So let me get this straight, you copy and past something, don't include quote tags or quotation marks and don't provide the source and then have the audacity to rant at me. Once again, very amusing.
Oh and out of interest, why did you do a slightly abridged C&P? Did you hope that by keeping pharynx but not throat in, people would be impressed by your attempt to sound sciency?
BTW, are you going to stop being a coward at any point:
