Living Bacteria Found Beneath Antarctic Ice

Cool! It'll be interesting to see if they can trace any possible ancestor to this bacteria, with only 14% similarity to known organisms it'll be difficult, hopefully they find some more that make a family of this type and have more to work with!

Russia finds 'new bacteria' in Antarctic lake
March 7, 2013

The samples obtained from the underground lake in May 2012 contained a bacteria which bore no resemblance to existing types, said Sergei Bulat of the genetics laboratory at the Saint Petersburg Institute of Nuclear Physics. "After putting aside all possible elements of contamination, DNA was found that did not coincide with any of the well-known types in the global database," he said. "We are calling this life form unclassified and unidentified," he added.

Bulat said that the interest surrounded one particular form of bacteria whose DNA was less than 86 percent similar to previously existing forms. "In terms of work with DNA this is basically zero. A level of 90 percent usually means that the organism is unknown."

"If we manage to find the same group of organisms in this water we can say for sure that we have found new life on Earth that exists in no database," Bulat said.

"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther

The truth is incontrovertible. Malice may attack it. ignorance may deride it, but in the end, there it is. ~Winston Churchill
