Very interesting, Fromz ... I wonder if there will be a DNA comparative analysis with these DNA and other more primeval bacteria. I'm assuming, of course, that they have DNA. What relation do these unique anaerobic bacteria have with aerobic bacteria? Did they come from related, parallel or separated processes? I'm guessing that the research on these kind of questions is still in progress.

that is quite interesting. i had not seen anything about that before. it would be interesting if they can learn more about early life forms from it.

Jon, I'm going to make a couple of assumptions about what they'll find.

Same chirality as all other life found, pretty much standard cell formation (wall, nucleus, etc) and a fair chance they'll find it's related to some of the other extremophiles found in the same area.

I suspect you're right. It would also be interesting to determine if similar bacterium or one-celled creatures existed in isolated environments elsewhere.

Extremophiles have been found everywhere they've looked.

I think the article did say this is the first anaerobic arsenic eater they've found. I took that to mean there are aerobic bacteria.

Here's a link to the Wiki article on extremes but you probably already know most what's there.

Yeah ... I was thinking of other anaerobic arsenic eaters ...

Thanks for the link ... have seen similar.

Life has been almost indestructible,

PAH! arsenic, this too can be used to multiply.

Leave it to us though, we find a way to snuff life forms out that have been here for eons.
