[citation][nom]serendipiti[/nom]Well, Arsenic on bacterya DNA which lives in an Arsenic lake ? It's not that strange (there are lots of comlex DNA "procedures" and "magic"). I could be some case of evolution and not a complete rebirth of life. Some other bacteryas from deep seas with vulcanoes need no sun to live, and since then I thought that they were searching just for water to find live.[/citation]
Bacteria that live by heated sulfer vents deep underwater are not entirely different from other species. They just aren't photsynthetic, they are chemosynthetic, meaning they get their energy from chemicals, rather than sunlight causing a reaction in them, like plants.
This bacteria is far different from any other thing found to date, granted it's not monumental, but it's vastly different than finding another new bacteria.
