Scientists Confirm There Was Life On Earth 3.5 Billion Years Ago (qz.com)
Paleobiologists have confirmed today that life forms existed some 3.5 billion years ago. The new study, published in the journal Proceedings of the National Academy of Sciences, uses the latest techniques to date the most aged remains available. Quartz reports: The research, led by paleobiologist William Schopf of the University of California-Los Angeles and geoscientist John Valley of the University of Wisconsin-Madison, has been in the works for what seems a long time to most, but which the academics know is merely a blink of the eye in terms of life on Earth. The specimens in question, mostly now-extinct bacteria and microbes, were found in 1982 at the Apex Chert, a rock formation in Western Australia, in a piece of rock. In 1993, based on radiometric analyses of the rock, and the shape of fossils, Schopf dated them as biological beings that existed 3.45 billion years ago. The rock held the earliest direct evidence of life, Schopf thought, and inferred from it that creatures existed over a billion years earlier than anyone previously believed. But some scientists argued that this claim was too speculative and that the microfossils, invisible to the naked eye, were really just weirdly-shaped bits of rock, strange minerals that only seem to contain biological specimens but do not.
Since then, technology has improved and Schopf and Valley teamed up to devise a new way to analyze the rock specimen, which now lives in the London Museum of Natural History. Valley spent 10 years developing a method to analyze the individual species that are shaped like tiny cylinders and filaments. Any type of organic substance (including both rock and microbe) contains a characteristic mix of carbon isotopes. Using a secondary ion mass spectrometer (a very rare tool, one of which is housed at the University of Wisconsin), the scientists were able to separate the carbon in each fossil into isotopes. That way, they could measure the carbon-isotope makeup of each fossil, and compare those to fossil-less rocks from the same era. [...] After analyzing the microfossils individually, they identified five species, concluding that two were photosynthesizers, two were methane-consuming organisms, and one produced methane.

And 3.5 billion years later life spends its days on Slashdot. Progress?

The Vatican doesn't want bump stocks banned & is spending millions of dollars to LOBBY AGAINST banning bump stocks. The VAST FORTUNE of the Vatican was obtained through illicit means including funding wars in Europe. The tradition of using VIOLENCE to grow the wealth of the Vatican is alive and well. Collectively, the Vatican, George Soros, and the NRA, are fighting (figuratively, I hope) to keep them legal. Jesus Christ is ROLLING IN HIS GRAVE.

It's no better than Hillary Clinton and the DNC paying shills to support George Soros and spread conspiracy theories about Russia. Slashdot must ultimately ELIMINATE MODERATION.
The real purpose of the Russia investigation is to DEFLECT ATTENTION away from the Democratic COLLUSION with the Vatican. Any alleged Russian meddling in our election was dwarfed by the Vatican meddling, delivering tens of millions of dollars to support DEMOCRATS. Notice how Democrats paid lip service to banning bump stocks & then took no action. On the surface, they appear to support gun control, but in reality Democrats align their agenda closely with the Vatican on nearly all issues. The Vatican is by far the biggest manipulator of American elections, but does so behind the scenes. That is why only one Catholic has ever been elected President and he was assassinated by the Vatican for going against their plan to remain IN THE SHADOWS.
Good posts (like this one) keep ending up at -1, and it makes Slashdot IMPOSSIBLE to read. Moderation (censorship) is RUINING this site. The moderation system has become a means for enforcing groupthink and SILENCING users like Creimer who become unpopular with a small group of MORONS with mod points. Once their karma is depleted by the ABUSE, they can only post twice a day, and at a score of -1. I post anonymously so my imposters can't silence me in the same manner. Otherwise, I would no doubt be their next victim based on the amount of abuse I take.
Most of the abuse is because I won't OpenSORES my Hosts File Engine. JEALOUS LOSERS are angry they can't PIRATE my code and because I tell the TRUTH about them in my posts. Most are angry because they keep DESTROYING themselves against me. It's really quite sad and pathetic.

Precambrian life forms are precambrian. Tekeli-li!
That means it only took life 1 billion years to evolve (shorter if you consider the early earth was inhospitable). That means it is really easy for life to evolve or strong support for pan-spermia ;that life was seeded from outside the solar system.

Without spending much time, I can learn so much on the net!
That's one way to get avoid prison.
been sitting here how it Was supposed
Doesn't sound like the real APK to me.
Schopf and Valley tried to find life in the Republican Party, but were unable to, so they did something easier instead.
rare STROMATOLITE, OLDEST fossil ON EARTH, APPROX 3.5 BILLION YEARS OLD`
Evolution is about adaptation to a changing environment.
"Progress" has no part in any of it - what does that word even mean? That word implies a goal (how else can you make progress if not towards some goal).

It has been generally accepted that there was life at 3.45Gya since 2013.

You old bastard.
At the end of all your lives, you will not be able to doubt that there is a God and that you will forever be craving water and a cooler climate.
Where they there?
Yeah well the guy always posts AC so he's asking for some saddo to come along and impersonate him. On slashdot, that's fucking inevitable.
I do not want your cheap brainburning drugs. They are useless for work. And I am a working man today.

Since Rock can become molten, but stay it's own substance, the radioactive dataing doesn't prove anything about the age of the fossil, especially since huge assumptions are made on how much of a particular radioactive substance there must've been to begin with. And certainly assumptions are made on how the fossils are formed. Just proving a few ways of how fossils can be formed does not mean that is how all fossils are formed. Radioactive dating is more akin to statistics which are know to be able to be manipulated, than scientific..
Yes, of course, none of those paleobiologists, geologists, biologists and other scientists, with their years of studies, followed by years of experience, could have possibly considered all the possibilities and taken into account the characteristics and possible limitations of their dating techniques.
Not like some random internet anonymous expert who's so much more experienced and knowledgeable.
Seriously, you must be very naive to think that your smokescreen of pseudo-scientific bullshit, which in fact only highlights your ignorance, could hide the fact that you're just a clueless creationist retard.
Reading your post was just like reading the falacious crap of some random flat-earther, for fuck's sake. I bet you voted for Trump, to.
Sorry space cadet, there is no solar system.
Check out the winter sun while you're thinking about that.
It's a being, but not as we know it.
"Trump!!", the new Godwin.
Something tells me that you're a fan of authority...
"Trump!!", the new Godwin.
And something tells me that you see in me exactly what you want to see. By your tone, you're obviously someone who systematically rejects anything that's even remotely related to authority, regardless if it could be good or bad. And the fact that you saw a link with authority in a post that's completely unrelated to it tells me that, frankly, you must be somehow obsessed with the concept of authority in your daily life.
See ? I can play armschair psychologist too.
I agree science must be challenged, but with valid logically sound hypothesis, not pseudo-intellectual bullshit like what the OP posted. As I said, he sounded exactly like one of those flat-earth fucktards.
Incase you haven't noticed, there's a concerted, delibarate, worldwide war against science. Scientists' integrity is being deliberately attacked, a delibarate gaslighting campain is being run against the scientific method itself. This is more than a war against science, it's a war against civilization itself, against reason, logic, rationality and knowledge over obscurantism, superstition, barbarism and savagery.
Choose your side.
After analyzing the microfossils individually, they identified five species, concluding that two were photosynthesizers, two were methane-consuming organisms, and one produced methane.
So two of them were conspiring to kill the other three. It took them a billion years, but they finally pulled it off.
I don't know which is more stupid - Believing in a supreme being that created absolutely everything or that somehow you can shake a bunch of DNA for billions of years and end up with conciousness. There is a very, very *very* low probability of either happening. At least the "God" theory admits that it is a matter of belief/faith.
All of Christian theology hangs on the fall of Eve and Adam and the world with it. Without this literal event nothing about New Testament theology makes any sense. That is why Creationism is very important. Jesus believed in the actual literal Genesis story and built his theology upon it. I personally don't understand how a Christian cannot believe in the literal Adam and Eve story and have a coherent belief .
(Disclaimer I don't believe it but I understand why they fight)
If you read the paper that is what makes these rock special is that they haven't metamorphosed.
This variant developed into politicians.
Circle the wagons and fire inward. Entropy increases without bounds.
Against!
