I recall the, at the time, ongoing conversation, you're talking about and had meant to post this and something here in the flesh world commanded my attention and when I returned, the conversation between Skombolis and yourself had pretty much ended, nevertheless, here is another example of a life form, here on earth, that doesn't fit into what we deem the requirements are for life, and further shows we have to allow much wider latitudes in what we can or could expect to find.FYI
Some posters might have read and remember a discussion between Skombolis and me regarding the likelihood of there being intelligent life elsewhere in the universe, part of which turned to a class of microbes called extremophiles - organisms that live in extreme conditions.
These were offered as evidence that life exists wherever it can, and that it is both adaptable and hearty - part of an argument suggesting that life elsewhere in the cosmos was essentially a given.
I just saw this at http://science.nasa.gov/science-news/science-... :
"Nearly 65 feet beneath the icy surface of a remote Antarctic lake, scientists from NASA, the Desert Research Institute (DRI) in Reno, Nev., the University of Illinois at Chicago, and nine other institutions, have uncovered a community of bacteria existing in one of Earth's darkest, saltiest and coldest habitats.
"A briny liquid, which is approximately six times saltier than seawater, percolates throughout the icy environment where the average temperature is minus 8 degrees Fahrenheit.
"Our knowledge of geochemical and microbial processes in lightless icy environments, especially at subzero temperatures, has been mostly unknown up until now."
"This system is probably the best analog we have for possible ecosystems in the subsurface waters of Saturn's moon Enceladus and Jupiter's moon Europa"
<Scientists discover first multicellular life that doesn't need oxygen>
"Oxygen may not be the staple of modern complex life that scientists once thought. Until now, the only life forms known to live exclusively in anoxic conditions were viruses, bacteria and Archaea. But in a new study, scientists have discovered three new multicellular marine species that appear to have never lived in aerobic conditions, and never metabolized oxygen."

I'd also like to point out that this opens the door wider and would tend to example that life may have been able to form here on earth in more conditions than we'd ever thought, since oxygen necessity has not become the norm or inviolate rule, even for an oxygen rich planet as earth is.
Abiogenesis is likely the rule - everywhere - and not this singular and "superfreeking" special event that we sometimes think our planet possesses.
I tend to think we're(all life on earth) special in that we have evolved to this point(however primitive or advanced we may be), but I don't think we're the unique and singularly exclusive life form in the entire Universe.
To think we are the only life in the Universe is akin to thinking there are only 300 fish in the entire world, and no other life at all...
Would be putting it mildly.
