I agree, but as this debate revolves around the science of evolution VS ID and creationist dogma, i think it is a little naive to simply say science has no cultural agenda when it has not completely answered the question. Science and technology have had massive cultural impact purely by being present. Science has the agenda of being specific, in this case it strives to describe and explain the origins of life as we know it. Unfortunately it does not tell us how to use this knowledge, how we as a culture interpret this in relation to how we live on a daily basis. In the majority of individuals lives, religion plays this role. I think it is significant to note that Religion strives to answer the very same question, yet it is an agenda because it fails under the scientific method. So as the views are opposing it is safe to say that Religion views science as having an agenda as it still has not adequately answered the questions on the Origin of Life. But i guess Abiogenesis is a whole other thread. LOL.

Scientific research has been around for a long time. It is by nature driven by man's thirst for knowledge. Science has no cultural position or agenda. Some scientists might have those attributes, but true research leads to knowledge and lets the political and social chips land where they may.
ID and creationism are but the present manifestation of the same dynamic, as religion tries to catch up and incorporate new knowledge into old paradigms.

So key innovation is not reliant on natural selection. Could not ID argue that this is infact a pro for them. That innovation may be an inbuilt mechanism and not a byproduct of a natural mutation to aid adaptation to ensure survival and reproduction.
That is what i thought, but if it was being outselected due to unfittness, how does the original mutation survive to become stronger through futher mutation? These characteristics only become valuable after further cellular innovation, and so become historically significant. This appears uneconomical within a cells engineering constraints and a conservative developmental framework. This is suggesting that there are two units of variation or selection, normally we would expect NS to promote the survival of a single variant and so fixing it in that state, until the next innovation etc.

It was still reliant on NS. The second mutation produced a citrate variant that was being outselected by the original e. coli variant. That is, it had lower fitness cf. original. However, when it finally picked up the third mutation, it was now fitter than the original. So it was being selected at each step (i.e. its ability to reproduce in its environment altered its 'success' cf competition).
This is why i think it is pro-ID. Is it inbuilt to potentiate, to promote or strengthen biochemical responses, that NS appears to have no effect on this trait, yet on moving further up the historical timeline of mutations sees the trait influencing future generations. This is almost suggesting a database of mutations with potential for future cellular innovation.
The historical contingency part is essentially showing that the final variants were much more likely following an earlier 'potentiating' mutation. When e. coli samples were taken before that mutation, the citrate variant did not appear. When taken after that mutation event, the citrate variant could appear. However, even then it was a one in a trillion event. Thus, the evolution of the final citrate variant was contingent on an earlier potentiating mutation - which was also very rare and random (i.e., couldn't be reproduced from earlier samples). In other words, the final citrate variant was dependent on earlier history (if mutation x, then mutation y and z possible).
I agree with the chancy part. But what i think this study is suggesting is that these cells display cellular innovation outside of the NS model. If a trait can appear after historically being deemed unfit, why should it then appear in the future, is this not speculation on potential.
Looks quite 'chancy' to me. In sum, the study suggests that the probability of producing certain traits can be affected by prior genetic history. If you want to say there was an inbuilt issue, it was the presence of an 'inbuilt' prior random mutation which potentiated the final trait.

Thanks for your reply. Some good thoughts for food, cheers.

I don't know about that mel, alasatro has a good point and how do YOU know this wasn't the intention of mutation? neutral? what is that exactly?
also I see many are upset with lenski for not being forthcoming with ALL his data.
Personally I think this is NOT random mutation but encouraged mutation but that's just me. The thing is even INTELLIGENTLY designed things man has made may make no intellgent sense at all to the casual obeserver not in the same field or simply for not having the intelligence to know what it is or why it is there.

Heh, so mutations now have intentions? A DNA mind?
A neutral mutation is one that has no effect on fitness - not beneficial, not detrimental.
Schlafly is a dope, sorry, he is. What does he want from Lenski? The e. coli samples? He wants Lenski to send him gut rotting bacteria? Send them to some dope who can't even read the original article correctly, who has no biochemistry training, no equipment to keep the samples, no ability to assess or use the data?
You're joking, no?
You do know that such samples require all kinds of documentation for safety reasons? And you think they should go to some random conservative theocrat?
.
Well, that's the beauty of such magical thinking, you can apply it to anything and everything. I guess the magical think n' poof of the designer caused the mutation, lol. But he only did it once, and refused to repeat it. In the later mutations, he did in once in a trillion.
As I said, con, you could apply this to absolutely anything. It is magical thinking at its worst.

I know, and that brings us back to the whole "God of the gaps" thing.
The odd thing is, science has never attempted to disprove the existence of god.
What happened before the big bang? Science has no answer for that, ad it's ok to say I don't know cause we really don't know. A christian might believe in his heart that the big bang was the moment of god's creation, but he doesn't know that.

Who said they were mutations? That's what I am talking about mel and how do you know they were neutral? Who are WE to decide what is beneficial and what is detrimental when we have'nt really got a clue?
Ha ha you got me mel,, damn you must read everything out there eh.
I was going to say "who said anything about shlafly?" but you got the credit coming where the credit is due.
I sort of expect the harsh criticism about him too,, you do that kind of thing with critics of your position too often to say it hasn't affected your objectivity but you DO surprise me from time to time.
Oh C'mon! Mel! You don't think Science does that every damn time a fake icon of evolution gets discovered or when the fossil record comes up short? Jeeziz man you don't think that is exactly what I am talking about having to listen to new explanations or to be more specific and drop dead cynical, PUNTUATED EQUILIBRIUM?
you could do is hold your sanctimonious toungue.
WE SIMPLY DON'T KNOW and you of all people
should know that

Thing is, con, there's no problem people questionning the veracity of these findings. We should do, it's a new study with new data. But I don't think Schlafly is capable of doing so in the way it needs to be done. Lenski was very nice to him to start off with, but Schlafly just couldn't help himself.?
But if you want to claim these mutations are supernaturally caused, you'd need to go further than just the assertion. How? By what mechanism? For what reason?
Why only once? Why not repeat it when the post-doc attempted with the earlier samples? Is the supernatural force just acting random? If so, how do we tell natural random from supernatural random? Are all mutations supernatural? When babies are born with two heads is that supernatural as well?
You can't just make the claim. Substantiate it.
It's a can of worms that is useless and vacuous. You can apply to anything, and indeed, people of faith tend to. As one crawls out of a earthquake and thanks god for saving them, whilst thousands have just died and been forsaken by the very same force.
It's just another empty faith-based assertion. But, again, if it floats ya boat, con. I'm cool with that.
