t’s life, but not as we know it. The oldest fossil ever discovered on Earth shows that organisms were thriving 4.2 billion years ago, hundreds of millions of years earlier than previously thought.
The microscopic bacteria, which were smaller than the width of a human hair, were found in rock formations in Quebec, Canada, but would have lived in hot vents in the 140F (60C) oceans which covered the early planet.
The discovery is the strongest evidence yet that similar organisms could also have evolved on Mars, which at the time still had oceans and an atmosphere, and was being bombarded by comets which probably brought the building blocks of life to Earth.
The team who made the finding at University College London believe that looking for similar fossils on the Red Planet is the best chance of finding evidence of alien life.
“Early Mars and early Earth are very similar places, so we may expect to find life on both planets at this time,” said doctoral student Matthew Dodd, the lead author of the study which was co-funded by Nasa.
“We know that life managed to get a foothold and evolve rapidly on Earth. So if we have life evolving in hydrothermal vent systems maybe even 4.2 billion years ago when both planets had liquid water on their surface, then we would expect both planets to develop early life.
“If we do future sample returns from Mars and look at similarly old rocks and we don’t find evidence of life then this certainly may point to the fact that Earth might have been a very special exception, and life may just have arisen on Earth.”
maybe they found something in antarctic when they had all those religious leaders go there. Lots meteorites there...and heck..one religion worships one.

When I spoke with him at VICE's Toronto office in October, the permafrost scientist—also known as a geocryologist, currently stationed at Moscow State University—told me that he's feeling just fine. In fact, he says he's feeling healthier and less tired than ever. His most famous claim is that he hasn't had the flu in two years, which he coyly says may or may not have anything to do with the ancient bacteria he injected into his body.
The bacteria in question is known as Bacillus F, which Brouchkov pulled out of a permafrost sample from Mammoth Mountain in the northern Siberian region of Yakutsk in 2009. (You might remember Yakutsk as the location Motherboard contributor Ben Makuch visited last year in our documentary, "Cloning the Wooly Mammoth.") Brouchkov believes that this bacteria was not merely preserved for millennia, but actually thrived under these conditions.
According to Brouchkov, Bacillus F has a mechanism that has enabled it to survive for so long beneath the ice, and that the same mechanism could be used to extend human life, too—perhaps, one day, forever. In tests, Brouchkov says the bacteria allowed female mice to reproduce at ages far older than typical mice. Fruit flies, he told the Siberian Times, also experienced a "positive impact" from exposure to the bacteria.
The problem is, he still doesn't know what, exactly, that mechanism is.
Brouchkov isn't the only scientist analyzing ancient bacteria pulled from the frozen depths of the northernmost regions of the world, though he may be one of the only few doing so in search of eternal life. For decades, scientists have been recovering bacteria from the Siberian permafrost and analyzing their properties. The CDC analyzed a giant prehistoric virus ("giant," because it's observable with a regular microscope) recovered from permafrost in a secret lab back in September, for example. Last year, researchers from the Russian Academy of Sciences sequenced the genome of a drug-resistant plasmid isolated from bacteria found in permafrost.
Such ancient viruses are incredibly complex, with hundreds upon hundreds of protein-encoding genes; influenza A has eight. In short, there's a lot we don't know about them.
Brouchkov's belief, that ancient bacteria may hold the key to immortality, is a more fringe view. When I first read about Brouchkov a few months ago, my main question was: is this guy for real? To find out, I emailed Brouchkov to see if he'd like to chat—on the phone, I imagined. But as fortune would have it, he told me that he was presenting at a conference in Montreal on his work, and that he would be in Toronto for just one day.
We convinced Brouchkov to swing by, cracked open some vodka, and toasted to freedom and eternal life.

That's an interesting article Sys . I believe the Mars 'Fossil Finder' mission may help provide more clues...
The article about the Russian scientist....That's concerning....
Suzy,,,,,,Have a cheese puff.....
I've mentioned this before but it fits here too.....One of my favorites.
Tardigrade in Moss
Explanation: Is this an alien? Probably not, but of all the animals on Earth, the tardigrade might be the best candidate. That's because tardigrades are known to be able to go for decades without food or water, to survive temperatures from near absolute zero to well above the boiling point of water, to survive pressures from near zero to well above that on ocean floors, and to survive direct exposure to dangerous radiations.
The far-ranging survivability of these extremophiles was tested in 2011 outside an orbiting space shuttle.
Tardigrades are so durable partly because they can repair their own DNA and reduce their body water content to a few percent.
Some of these miniature water-bears almost became extraterrestrials recently when they were launched toward to the Martian moon Phobos on board the Russian mission Fobos-Grunt, but stayed terrestrial when a rocket failed and the capsule remained in Earth orbit. Tardigrades are more common than humans across most of the Earth.
