New Evidence About 'The Great Dying' 250 Million Years Ago
PornMaster writes "The Guardian is reporting that scientists have found the first direct evidence that the killoff of 80% of land species and 95% of marine species 2 billion years ago was due to a meteor." The project web site has more info, maps, etc.
not "first evidence"...
just like in judicial cases you can have circumstantial evidence, scientific hypotheses can be supported by indirect evidence.
"...scientists have found the first direct evidence..."
Direct evidence my arse. Scientists have found a few holes in the ground and some sediments. It amazes me that so many people just blindly accept these theories (and they are only theories) about meteors wiping most of the life out on earth long ago.
there can be hundreds of pieces of indirect evidence and logical arguments supporting a meteor hit.
this is the first direct evidence i.e. they found the meteor (or what's left of it).
I'd say that if everything points to a meteor, and then you find the actual meteor, then that's as far from "sketchy" as possible and has very little to do with "belief".
250mil years of evolution? That sounds about right.
Finding a very thin layer of irridium in the rocks laid down at the very end of the Permian would be compelling evidence. A layer of irridium, together with the crater in the Gulf of Mexico off the Mexican coast, made a good argument of what caused the dinosaurs to go at the end of the Cretaceous period.
WHAT?!? somebody actually questions the theory of evolution?? He must be a fundamentalist! Off with his head!
actually, if you look at the hard evidence, the whole concept of macro-evolution is nothing more than a wild guess in the dark. the theory is full of holes and most of the logic doesn't completely add up. but i guess people have to believe in something.
The article doesn't question the theory of evolution....
The darkness... controls the music. The music... controls the soul.
You're not "supposed to" believe it, where did you get that idea? Clearly you have no idea how science functions, why don't you learn what science is before publicly criticizing it? It is obvious from your post that you don't even understand the basics of the scientific method, despite the fact that you think you "know a bit" about science.
If you actually read up a bit about this, the scientists here are basically saying that this MIGHT BE a possible cause of one of the great extinctions (read "more research required"). Furthermore, this is now just one new "HYPOTHESIS" against two other major "HYPOTHESES" that alread exist that proposing other "POSSIBLE" reasons for this great extinction.
Certainly nobody has asked you to "believe" any of these possible explanations, and none of the scientists involved have claimed that their hypotheses are 'the truth' either. In fact, with things like this, scientists never really decide that any one theory is "the truth" - they basically often settle on a theory that is "the most likely" - they, however, ALWAYS "leave the door open" to other possible explanations that may appear in future that are better. Always. (This is all in refreshing contrast to religions like Christianity, where you are in fact expected to 100% completely believe something regardless of whether or not there is really evidence for it.)
The slashdot blurb has also spun this thing completely wrong. So even worse, now you make decisions about scientific theories based on a slashdot blurb. Sheesh.
It would seem the moderators don't see alternative viewpoints as neither valid nor worthy of discussion. I thought /. was about voicing on-topic opinions. Apparently I was wrong.

Um, if you RTFA, it never says that the murder is 2bn years old. It states the the history of life is 2bn years old. And if you read his post, you'll realize that he's talking about the headline, which says "New clues to 2bn-year-old murder". Don't be so liberal with your RTFA's. On a side note, I think this headline highlights a trend I've been seeing in which internet news agencies create misleading or incorrect headlines just to get people to click on them. They're generally remotely related, but tend to say things that aren't supported or even covered by the articles.
Like what?
But, when the science claims that then have evidence but no direct evidence I am supposed to believe it.
No. You are supposed to think that it represents a likely scenario and it is a plausible explanation of what happened. There is no "belief" in science, other than as a figure of speech.
How on Earth you arrive at that conclusion? The big extinction didn't kill everything or wind speciation back to step 1. The meteor didn't kill off 80% of species and then magically devolve the remaining 20%.
Ultimately, I think, it comes down to faith.
No, no it does not. These scientific theories really do work, as you witness every day when you use a computer or a TV set or a DVD player. Whether scientists are right about, say, the speed of light or radioactivity does not need to be taken on faith.
Remember, creationists aren't just disputing some evolutionary biologists somewhere. They have to dispute physics, geology, cosmology, basically anything that gives you a dating method or shows what the place was like billions of years ago. Just about every branch of science eventually matures to the point that it burps out evidence the Earth or universe is old.

they're down to a mere 200 million years to go from single-celled to upright and walking.
No.
Why post about something you clearly have no interest in understanding?
_All life_ didn't die out 250M years ago. All the _evolution_ done up until then lived on.
it's in my head
Given that they've already posited that mankind's ancestors appeared about 50 million years ago, they're down to a mere 200 million years to go from single-celled to upright and walking.
Huh? Are you confused or just stupid?
And the worst part is you've been modded up as insightful. It's insane. Come on people, visit a goddamn library, or do some googling, or something! This post is total BS, and it doesn't take a genuis to confirm against actual scientific theories that this is total BS.
From Carl Sagan:
... The method of science is tried and true. It is not perfect, it's just the best we have. And to abandon it, with its skeptical protocols, is the pathway to a dark age.[1] "
"In science it often happens that scientists say, "You know that's a really good argument; my position is mistaken," and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
That's just it. Good science (as opposed to junk science) does not assume anything of the sort.
You observe. You collect evidence. Then you interpret the evidence to see if it matches any posited hypothesis. Usually, you put forth an hypothesis first, and then you test to see if your evidence fits.
You do not massage data to make it fit, unless you have an agenda to fulfill.
Leading univeristies have proven they can accually stop light, hold it in place, then speed it up on their command.
Well, firstly, that is not in empty space, which as I hope even you believe, is what exists between the stars.
Secondly, if light was stopped for a while, that would mean it took *longer* to get here from the stars, which would mean they were *even older* than millions of years!
For your argument to work, light would need to be speeded up. No-one has done that, of course.
(Also, they aren't really stopping light at all: they are simply storing the information in the light and then re-creating the light later).

It's a fight for mindshare.
This is absolutely correct. It reflects very accurately the situation in which we find ourselves: athiests feel threatened by the religious, faithful feel threatened by the non-believers. Why are we threatened? On the whole all of the people involved are decent, respectable folk, who would enjoy chatting with you on the street.
Once the battle lines are drawn (athiest vs. religious, liberal vs. conservative), though, it gets ugly. People on feel they are being attacked, and get worried that their way of life is being threatened by people who don't think as they do.
The greatest fear is that someone who thinks the other way will get into power, then force their beliefs on everyone... [Clinton, Bush, control of the SCOTUS]
Or worse yet, what if they indoctrinate the next generation! Hence the anger against the perceived secular/liberal control of the education system. This is why home schooling is becoming so popular: "They won't teach my child their godless/heathen/hippie ways! I won't have my kid brought up like that!"
If people believed that the President, or public school teachers, or the Supreme Court, or the local pastor, were rational, respectful people, who would do right by the community, this wouldn't be a problem.
