http://www.sciencemag.org/...ontent/abstract/science.1190719 Research Articles We report the design, synthesis, and assembly of the 1.08-Mbp Mycoplasma mycoides JCVI-syn1.0 genome starting from digitized genome sequence information and its transplantation into a Mycoplasma capricolum recipient cell to create new Mycoplasma mycoides cells that are controlled only by the synthetic chromosome. The only DNA in the cells is the designed synthetic DNA sequence, including "watermark" sequences and other designed gene deletions and polymorphisms, and mutations acquired during the building process. The new cells have expected phenotypic properties and are capable of continuous self-replication. 1 The J. Craig Venter Institute, 9704 Medical Center Drive, Rockville, MD 20850, USA. * To whom correspondence should be addressed. E-mail: jcventer@jcvi.org

I didn't read this article but read the more layman article in the New York Times I believe.....so thoughts on what this means? Could this guy (a brilliant guy no doubt), just proven that life, *gasp*, requires some sort of designer, or a "god"???? Or is this not that big of a deal and all it means is that this genius of a scientist is advancing science? Edited by Flyer75, : No reason given.

In my (obviously humble) opinion, what this shows is that there is no limitation to what can occur through mutation and replication. Why? Because it shows you can take random molecules and assemble them into any form of life you desire, replicate any known organism, and the result is a viable living reproducing organism. You could take one organism, deconstruct it and reassemble it into another. Any such change could occur by mutation in a natural process.

What Venter and company did was sequence a bacterial genome, duplicate the genome in a sequencer, inserted the sequencer-made genome into a cell replacing its natural genome then watched it continue to live and reproduce. No great surprise, here. An Adenine molecule in position 2754 on chromosome 8 is chemically identical in form and function to any other Adenine molecule whether it was placed there by the cells natural mechanisms or by a sequencer unit. What is significant about this experiment is that this is the first time in genetic engineering an entire genome has been sequencer produced without any of the naturally produced genome used in the resultant cell. This is significant in that it evidences that no spooky supernatural power, element or “breath of god” is necessary (since the sequencer unit is incapable of producing such things) in the genome for the processes of life to occur. Though it does not disprove a designer, rather than evidencing a designer this experiment shows that the operation of the genome is purely, and only, chemistry. Second, though it is still cheaper and more effective to leave the natural genome in place, changing only those parts we want artificially to produce whatever application we are trying to achieve, as our knowledge of the intricacies of the genome and the resultant proteomics progresses, it may become more feasible to sequence an entirely unique genome to insert in a cell and we now know we can do that.

The potential of this process for biogenic drugs is ... inspiring. My last chemo drug was biogenic -- produce by bacteria bred to make it in quantity.

Indeed. The potential benefits are staggering. Unfortunately so are the potential dangers. We'll both keep our fingers crossed.

Absurd. This particular life form was created by an intelligent designer. It proves that intelligent beings can create life. It does not prove in any way that all life, or even any other life other than this specific example was actually created by an intelligent designer. If I make a pile of rocks, does that mean every rock pile you ever see was made by an intelligent piler?

Good grief Rahvin, lighten up a bit would ya. The point is and it cannot be denied, this new life that was made, had a creator. Are you going to deny that??? It had a designer. It's hard absurd what I said. Edited by Flyer75, : No reason given.

AZ, Could you enlighten me to the pros and cons of this. I'm about as dumb as the pile of rocks that Rahvin just designed when it comes to this subject. Seriously. You mentioned the drug benefits....how so? And then you mentioned the dangers.

He didn't deny that this life was "created". He simply pointed out the flaw in your reasoning: that you claimed this proves that all life must have been created. Surely you see that? Respectfully, -Meldinoor Edited by Meldinoor, : Clarity

Pros: Need a drug or chemical manufactured in large quantities quickly and cheaply? Design a bacteria that eats something relatively mundane (corn mush for instance) and that poops what you want (most likely along with other stuff hopefully easily filtered out). Or how about a bacteria that eats staph infections? Cons: Maybe you mess up and the bacteria that you engineered to eat staph and be nearly immune to antibiotics (so they could be used in conjunction) ends up mutating and instead of eating staph now eats flesh like staph. Now you just created a super-infection. Or maybe your corn-mush-eating-insulin-pooping bacteria gets into a farmer's corn field and turns it into insulin-on-the-cob and ruins the crops (maybe kills some people too).

As RAZD and Phage mentioned the benefit of having a bacteria spawn in great beer vats producing whatever drug of choice from insulin to biogenic amines will make such treatments more widely available and drop the costs to pennies per hundred doses instead of $$ per dose today. Today most, if not all drugs, are proteins or molecules discovered and taken from natural substances. Designer molecules are difficult and expensive to make, even for testing purposes, and designer proteins are next to impossible except in the most simple short-chain varieties. Using designer genomes in bacterium will change this. How about a designed bacterium that eats and cleans-up after an oil spill in some place like, oh I don't know, like maybe the Gulf of Mexico? The dangers are legion. Besides the obvious human design errors that could inadvertently be placed into a bacterium with unintended consequences how about intentional designer plagues? The prospect of an Ebola-like hemorrhagic bacteria specifically targeted only to Blacks, Semites or Northern Europeans comes to mind. Edited by AZPaul3, : No reason given.

Thanks for the answers guys. Ya, seems like a ton could go wrong somewhere along the lines. Not to mention how long it's going to take for the FDA to actually approve the drugs themselves.

It should be noted that a lot of Creationists do not even consider insects to be "life", because they are not nefesh creatures with blood. the bible states that the "life is in the blood". While we should expect lifeforms to certainly require an intelligent agency to put in the quartinary coding, I don't necessarily think that we should expect supernatural activity to be necessary when we are basically obeying the priniciples of nature. i.e. It would be very odd if DNA did not work, given that we would expect it to in an orderly universe whereby certain mechanics should work, as they are set-up to work.
