[QUOTE=BackflipHatchetAttack;26452468]Wait does this mean that oxygen, hydrogen, etc are not present at all or does it mean that just phosphorus is replaced by arsenic?[/QUOTE]
Phosphorus is replaced by arsenic.
I think NASA will harvest this things and send them off into random places in our solar system
Why is everybody surprised that theres stuff so different than on Earth? I imagine the first contact with "alien life" we have will be on a molten planet full of slow moving trees made of tungsten, or something unexpectedly random. I mean, what are the odds [i]we[/i] ended up the way we did?

Why the fuck would they do that? That is an incredibly stupid idea.

Surprised nobody pulled out the 'God wills it.'
Anyways, this find is incredible. For all we know, this could have been some sort of site in where aliens just quickly pulled on to a planet to take a quick piss, or some intergalactic trash truck accidentally spillt some of it's waste onto our planet and some survived the burnout on the atmosphere and landed in our nice lake in Cali.

What ?
did you read the OP ?

It's called speculating the origin of the bacteria.
I was expecting something like Cloverfield's sperm. I'm relieved. :ohdear:
[QUOTE=Kagrenak;26447938]I'm still not sure that the makeup is completely different. Genes could be the same. If the genetic code is completely different from anything we know; then it's a second origin point of life. If the genetic code is the same, somehow the phosphate in their DNA got replaced with arsenic and is staying that way throughout the generations.
Either possibility is immensely fascinating and important, however.[/QUOTE]
I don't think evolution works at the molecular level of DNA but rather with DNA sequences.
[QUOTE=topic10;26451876]This is amazing... but it kinda bothers me that only now we are finding this out.
Did these bacteria evolved here on earth? Or did they arrive here not long ago?[/QUOTE]
If they evolved here it couldn't have been at the same time as everything else, it seems to be they would have evolved to something more complex than bacteria over time and we'd be seeing a lot more creatures of this dna structure around.
man, i guess all the research put into mono lake paid off

This is really, really, old actually.
Hey guys, turns out this is completely false and we simply have micro-organisms that "tolerate" arsenic:

While still cool, micro-organisms exsisting in harsh conditions is not anything new.
This is amazing!

Most new theories are bashed by the science communities.

Considering we don't even know about all the non-bacteria species, the massive amount of bacteria generations and a few other factors, the discovery of a new bacteria species would not be that major. It's just possible that this species somehow down the line managed to replace phosphorous with arsenic.
Reminds me of the story with the e. coli evolution where they were able to use a different energy source. It's different of course, but both kinda show the adaptability of life, most of all bacteria.
How do we know it's alien DNA.

you know alien means foreign or unknown right? just cause "alien" is mention dose not mean it came from outer-space.
Arsenic doesn't entirely replace phosphorous, though in a question during the press conference, they dodged the question and failed to say how much.

Yes but I doubt that's what the OP implied or it seems purposely misleading to get more views.
[QUOTE=Mac2468;26455119]I don't think evolution works at the molecular level of DNA but rather with DNA sequences.[/QUOTE]
Evolution isn't necessarily restricted to DNA. It can use anything as long as it can reproduce and mutate, be it molecules, dna or bytes of computer code.
[QUOTE=Explosions;26460059]Yes but I doubt that's what the OP implied or it seems purposely misleading to get more views.[/QUOTE]
That's the reason the press always uses words "Alien" and "Ufo".
[QUOTE=noctune9;26462435]Evolution isn't necessarily restricted to DNA. It can use anything as long as it can reproduce and mutate, be it molecules, dna or bytes of computer code.[/QUOTE]
Even non-living systems such as TNA and PNA protein molecules can make copies of itself. The copies are not perfect, so if it has environment that challenges the properties of the copy, evolution works.
The only "hypothesis" that I could really come up with this, is that the bacteria were gradually introduced into their arsenic rich environment, the bacteria without the mutation that allowed for increased tolerance to arsenic compounds slowly died of, while the survivors gradually introduced arsenic into their physiology.
