Evidence of the Missing Link Found?
HUADPE writes to tell us CNN is reporting that scientists in northeastern Ethiopia recently discovered a skull that they think may be evidence of the "missing link" between Homo erectus and modern man. From the article: "The hominid cranium -- found in two pieces and believed to be between 500,000 and 250,000 years old -- 'comes from a very significant period and is very close to the appearance of the anatomically modern human,' said Sileshi Semaw, director of the Gona Paleoanthropological Research Project in Ethiopia."
the flying spaghetti monster burried it there!

"...between 500,000 and 250,000 years old..."
9 comments and there no "Earth os only 6,000 years old" comments yet. It's a good day.
Cue evolution vs. creationism debate in 5... 4... 3... 2...
Seriously, I almost dread stories like this for a couple of reasons:
- Talking about "missing links" puts the idea in creationists' minds that the evolution from apes to man took place in discrete steps, and that the fact that such "missing links" exist is proof that the Theory of Evolution is still just a hunch unsupported by proof. The fact is that the evolution from apes to man is a continuum, and there are a lot of fossils from lots of time periods along that continuum.
- Because this discovery is relatively recent, there's a chance that it still may turn out to be something other than what this article purports it to be. The real research is just starting. If it turns out that it's for real, it will be valuable insight into our species's evolution, though creationists will still refuse to believe it. If it turns out to not be an intermediary between Homo erectus and Homo sapiens, the creationists will accuse the scientists of everything from fabricating evidence to trying to pull a hoax as part of some weird conspiracy. The irony is that if it is discovered that this fossil is not the intermediary that it is suspected to be, it is scientists who will determine that, and unlike creationists who have a nasty habit of wanting to dismiss or even repress evidence, those scientists will let us know as soon as they find any inconsistencies, and the data will be there in the open for us to evaulate and form our own opinions.
I still say that this is the true test for whether a creationist can actually be open-minded or not. Ask them this one question:
What piece or pieces of evidence will it take to convince you that the Theory of Evolution is, in fact, true and that creationism is not?
If the answer is "None," as it is with almost every creationist I've ever met, then don't bother wasting your time arguing with them. Nothing you say will ever convince them, as they have deliberately closed themselves off to any kind of rational conclusion based on reality instead of blind faith.
The nice thing about the question is that it's not a double standard. There are several things that would convince me that creationism is true and not evolution. The most obvious would be if God came and spoke to me in a burning bush. I know that sounds facetious, but it's really not; that really would do it. Or, if compelling scientific evidence were to arise that evolution is a crock, such as discovery of a natural chimera skeleton. These are just a couple of examples, I'm sure there are many more.
I'm always amused at creationists who think that scientists are in some kind of dark conspiracy to push "the agenda" of evolution. What they don't realize is that if a scientist could discover some piece of incontrovertible proof that the Theory of Evolution is all just a bunch of hooey, he would undoubtedly be one of the most famous people in the world, winning all sorts of Nobel Prizes and recognition in his field. Proving the Theory of Evolution wrong would be one of the greatest, not notorious, scientific finds ever, on the level of Michaelson-Morley experiment that proved that there is no aether and set the stage for Einstein's Theory of Relativity, and you'd better believe that any decent scientists would kill to disprove the Theory of Evolution.
..that happens over time. We just happen to dig up random fossils and see dramatic changes from the previous, older species. We forget that there were sometimes 10,000's or 100,000's of years in between the two species.
There isn't one "link" between two species. A situation where one day a parent gives birth to a dramatically different, more advanced offspring that is more evolved then the parents doesn't happen. And even if they was a missing link, the chances of that fossil surviving and us finding itwould be near impossible.

To a depressingly huge percentage of the US and UK population this will just disprove THE THEORY even more. They'll point out scornfully that you now have TWO missing links where previously you jst had the one. 'Silly scientists' they'll say to themselves, laughing ruefully as they prepare for their next bible meeting.
...or is "the missing link" found every couple of months?
(1) This is only one skull. Weigh in the likelihood that it could be just a deformity of something distinctly not a missing link.
(2) Evolution occurs through generation and elimination of lines. Is there even the slightest evidence that this is not from one of the extinct lines? It's fully possible (and likely) that the species in question doesn't even have modern living descendants.
(3) If it *looks* like a human....
(4) And for good measure, color me suspicious that the estimated age is on the same order of magnitude as the estimated error in that measurement.
When things get complex, multiply by the complex conjugate.

'Sileshi' -> 'His Lies'
See? It's obvious that this man is the devil and is trying to test our faith with false fossils and his lies.
Mother, do you think they'll like this sig?
"The fact is that the evolution from apes to man is a continuum,"
Sure, but you should be careful. Saying it that way is a bit confusing too. It is a *branching* continuum. To say "from apes to man" is as much an oversimplification of the situation as saying a tree looks like a single stick. Life diversifies and spreads out during biological evolution, and extinction prunes the tree along the way. Many branches can exist at the same time, and it is challenging to find fossils from the branch points themselves (if you think of the sum total of wood in a tree with branches all the same diameter, the branch points are only a small fraction, and that's assuming you have all the wood from the tree preserved).
Exactly where this skull fits in is debatable, but the authors are reasonably confident is from a time when there are few remains known, close to the branch between Homo erectus and Homo sapiens, so it is bound to be an interesting addition to the puzzle.
I clicked the link and all I got was 404 page not found, I guess it really is the missing link :)

Yes, and if you had a server room temperature IQ, you'd have noticed that I in fact posit that in 250,000 years they will continue to do so.
So far, I've only skimmed the /. comments, but i'm getting some pretty distinct bad feeling against christians here... I'd just like to make one thing clear; not all of us christians are into bible-thumping and trying to put the 'fun' back into 'funadmentalist'. I've always considered God to be a craftsman. mayber there's just the off chance that this '6000 years' bollocks is because humans can't count in terms of the infinite. sounds weird, i know, but hear me out. we've already managed to establish a decent and pretty reliable form of carbon dating, yes? comparing half-lives of fairly inert materials gives us a good idea of temporal scale, right? maybe the seven days that the bible mentions is God's idea of seven days, and not ours... i think it's fair to say that the first, say, 5 billion years of the planet's existence were the prototyping stages; the whole 'right, i've got the ball of rock, let's make it habitable' period. we're already starting to consider some of the problems that we'd come up against when it involves terraforming, so it's fair to say that if you include planetary formation into that stretch of time, it increases significantly.
i reckon that yes, God made us; there's got to be a motive force behind it all: i believe it's a sapient beneficiary; otherwise we're all gonna go nuts with loneliness, in the existential sense. however, i also think that evolution is a matter of prototyping, and the design process. not all of us religious types are unreasonable; some of us realise that our holy books may have started as the word of God, but they were ultimately recorded by Man.
just my two pence. if you're gonna shoot me down in flames, then please do it in the form of a decent argument. otherwise, you're just as bad as the next fundamentalist...
http://xkcd.com/313/
One nineteenth century minister, considering the then brand new evolution debate, had an idea.
When Adam was created, why didn't he immediately collapse from low blood sugar? Because he had the products of digestion already in his veins -- he probably even had the remains of a meal in his belly. This was a meal which he never actually ate , as moments earlier he'd been an inanimate lump. A human adult is the product of a long developmental process; his bones and sinews are knit through a lifetime of activity, which in Adam's case never happened. Adam was conceived as if he were the product of an ongoing process, even if that process never happened. And thus Adam would have had a belly button of course.
If not Adam, why not the world, and all the creatures in it? Clearly the world God conceived, in order to operate, would have to be the product of a similar process of development, and it would show all of the manifestations of that process, even if that process never actually happened. Indeed, evidence for evolution would be the very hallmark of the Creator Himself.
This seemed to the poor fellow a splendid idea. He felt certain the the religious side of the debate would lay down its arms and embrace evolution. Naturally, he was completely wrong. The religious side of the debate was the forerunner of the modern Fundamentalist movement, and much preferred a science whose purpose was to prove religious dogma. Under this naive man's idea, the free inquiry into evolution becomes practically sacred, something that no human authority has any right to tinker with.

(1) Residual magnetism-- moderately reliable, but a healthy margin of error.
(2) Other isotopes-- there's other airborne materials that can be used in ways similar to c13.
Modelling-- as a species that's been building stuff out of earth for a million years or so, we've developed a decent set of analysis tools for the materials involved.
(4) No, they aren't (dated solely by fossils contained, except by your volunteering park ranger tour guide)
(5) Cyclic distribution patterns -- we have these things called 'seasons' that cause regular yearly variations in deposition of sediment, wear on rocks, etc, and there are various other such cycles (lunar, etc.)
(6) Relative distribution-- we can tell what came before what in an area by fossil distributions, comparing distributions gives us a general idea of the timescales involved.
I know you're just trolling, but in case anyone legitimately wanted to know the answer to your question, I figured I'd post enough info on the subject to at least point them toward topics of interest in the field.

If fossils cannot generally be carbon dated, how do you tell the age of it? We can also date fossils by geological layers in which the fossils are found. But how are geological layers dated? By the fossils that are found in them! This is circular reasoning!
This is a straw man argument. Nobody is claiming you can use radiocarbon dating on anything but recent fossils. Geological layers are dated by a variety of means, including radiological dating of isotopes much longer-lived than carbon-14. I watched as much of the video you linked to as I could stomach, and I think a few of my brain cells committed suicide in protest. Why are you taking this creationist crackpot seriously?
Really? He taught high-school science for fifteen whole years? Wow, I bet he knows more than the millions of serious scientists that disagree with him! Those high-school teachers are smart.

Well, no. The problem is that evolution as a theory has many different forms accepted by today's biologists and scientists. Evolution has been molded from its original versions back in the 17th and 18th centuries into what we see today. When certain aspects have either been proven wrong or shown quite improbable, most of the accepted theories of evolution change to account for it. It almost reminds me of the formation of denominations in Christianity.
I'm going to assume that you believe in God, from your post. If not, please by all means disregard what I'm about to say. Trying to score a point for God will never happen at the creation vs. evolution table. Like you said, it's impossible to prove or disprove the existence of God, unless God proves himself. If the theory of evolution is ever completely debunked by man, those who "convert" from evolutionism will likely find some other theory to put force behind that still doesn't affirm God's existence.
And yes, I'm a Christian and I'm not here to get into the creation/evolution debate. I used to be a firm believer in evolution, so I know many of its weaknesses and not once have I been successful in sharing the news of Christ by attempting to disprove evolution. I can vouch that the general concept of macroevolution is fundamentally flawed at most every level. But that's like declaring a problem without offering a fix... it comes down gracelessly and makes it less likely for a person I'm conversing with to actually come to me for answers.
Sharing Christ effectively means putting behind such useless debate. God proves himself without our help, so all we can do is share his word in a loving manner and tell those we care about what He has done in our lives. And if that's hard, we can point them to useful Bible reading. Take for instance the book of Romans, where Paul debunks some of the myths about God which are sadly still believed by very many Christians today and have become the unloving face of Christianity that repels non-believers.
All my liberal friends think I'm a conservative, all my conservative friends think I'm a liberal.
Animosity against Christians? Oh hogwash, that is just a vast oversimplification of a set of very complex socio-political dynamics which play out here on Slashdot. Christian folks like yourself are quite welsome to join in and partcipate in any capacity.
Anyway, we have some activities planned this afternoon over at the Coliseum. Invite your friends, and don't forget to bring a loincloth. Lunch will be served.
There's a Starman, waiting in the sky / He'd like to come and meet us, but he hasn't got the time.
Uh, not quite. There is a lot of compelling evidence for evolution. There's not a scrap for God. Its all faith.
Both sides rest on circumstantial evidence, and have been mounting a lot of it for a long, long time.
WTF? What does that sentence even mean?
You say that nothing will sway the creationists; I say that BOTH sides are firmly entrenched on this issue, and it's going to take a lot more than circumstantial evidence to convince either side.
The creationists have faith; this is irrational belief. If they want to go ahead and argue that its irrational, I certainly wouldn't stop them. You are framing this like it is some kind of CNN two-party debate. Listen carefully: there are not two sides. There just aren't. There is empirical evidence for evolution, and a bunch of people who refuse to believe it. That's it.
If Jesus wants me it knows where to find me.
I don't think you mean "disparage", meaning "To speak of in a slighting or disrespectful way; belittle", because disparaging a theory is not part of doing science. You probably mean "disconfirm" or "disprove". The reason scientists don't try to disprove evolution - by which I mean the common descent of all life on earth from a small set of ancestral organisms over about three billion years - is that there is an immense quantitiy of interconnected evidence that supports it. DNA, fossil evidence, biogeography, etcetera. Trying to claim that life isn't the product of evolution is like claiming that ordinary matter isn't made of atoms. Scientists do attempt to explain particular facets and processes within evolutionary history, and in doing so they necessarily argue over particular theories. This leads to...
There is no way to definitively prove one that either evolution has occured or that God created everything. Both sides rest on circumstantial evidence
Not at all. Evolution rests on evidence, yes. The evidence is widely available, can be examined by many, many people, and is agreed on by people with widely varying religious, philosophical, and cultural beliefs. As a theory, it makes predictions about things we haven't seen yet (such as the fossil skull in the article) and more importantly, predicts things we will not see, such as Precambrian reptile fossils, or mammals with feathers.
By contrast, the idea that "God created everything" rests on no evidence at all. It makes no predictions about things that we will see or not see in the world. There is no conceivable evidence that would weigh against it. In short, it's not science.
The process of evolution is a fact, backed up by mountains of evidence. We can even see it happen over short timescales of a few days or weeks.
The exact details of how mankind evolved are always being rethought and sometimes we discard an old theory when we find contrary evidence. Nothing in our lack of knowledge or the mistakes of the past invalidates anything related to the theory itself.
I think that creationists sometimes have an opposite problem as well. They may well be happy to accept the fact of animal evolution but be unable to apply it to mankind. Their church teaches that Man is "special", made in God's image and so on, and so therefore Man could not have evolved from Apes or lesser species.
It's probably a case of one's religious beliefs causing bias in the evaluation of the independent evidence supporting evolution. www.philosophers.co.uk has some great games related to religion and logic, and they explain the results they get from large numbers of people playing their games.
Here's a relevant analysis from the site:
And here's another relevant quote (this one from the 'Taboo' game)...
The analogy is that refusal to accept the theory of evolution despite the many, many facts in its favour is a consequence of one's deeply held religious beliefs causing an inability to rationally evaluate new (and conflicting) evidence. To accept wholeheartedly the truth of the evolution theory may require abandonment of prior beliefs. The adherent has some investment in those beliefs, and to abandon them is just like selling shares when the market is low.
On the other side, there are those who say that there is no Easter Bunny. The eggs and candies are delivered/hidden by other humans.Damn those Easter Bunny deniers and their closed minds! Damn those secular "Human Deliverers".
You say that "Intelligent Delivery" is the "middle ground". The existance of the Holy Hopper is not questioned. But he delivers the eggs and candies through his influencing human minds.
The Written Rabbit tells us only that He does deliver the eggs. It does not say HOW he delivers them. Intelligent Delivery is the answer.
Again, your comment was mod'ed up?
A writer promotes the isolation and eventual hunting and eating of a huge fraction of a country's population, based solely on their beliefs, which he sees as evidence of hopeless intellectual inferiority. His statements receive overwhelming agreement from the forum in which he is published.
How is this viewpoint is morally superior to those which wrought genocides in Biafra, Croatia, Nigeria, Rwanda, East Timor and dozens of other places in our lifetimes? Are we really so willfully ignorant that we believe all these atrocities didn't start this way? So filled with hubris that we believe America (or our intelligencia, which has itself been targeted in other times and places) incapable of such virulent hatred?
If you still aren't taking me seriously, consider this: Orthodox Judaism posits a literal six-day Creation. If the writer had singled out this group instead of attacking all Genesis believers and the geographic region which he believes contains them, would any of us have called his diatribe anything but hate speech of the most vitriolic and unconscionable sort?
Please read the parent post again, examine its +5 Insightful score, and tell me how far removed we are from that mindset. And please be intellectually honest; if you plan to claim that BadAnalogyGuy was only trying to be funny, or that the moderators were only moderating ironically, please provide supporting evidence.
Meanwhile, you have still been unable to explain why your proposed "middle ground" contains a supernatural being who is exempt from evolution AND intelligent design/creationism.
No, your "middle ground" is nothing more (or less) than wrapping the scientific findings in your belief that "God wanted it done that way".
Science is not faith.
Faith is not science.
There is no "false dichotomy".
"Missing link"? That's not scientific terminology, and it hasn't been scientific terminology for many, many decades now. The only ones talking about "missing links" these days are creationists who are under the impression that Darwin's Origin of Species is the latest and the greatest on the science front.
My other body is also not wearing any.
There's genetic replication, and there's memetic replication. Since time immemorial, the cultural and political elite have had smaller families (the Catholic Church is the most extreme example of this--a celibate priestly caste exerting near total cultural hegemony for over a thousand years.) Aristocrats, scientists, artists, and clerics have all tended to have fewer children, and recruited from amongst those who do bear children to replenish their numbers. Slippage does occur, but the pressure of loss of prestige and influence will drive even the most reactionary forces to moderate their positions; tolerance and a willingness to consider new ideas confer too much of a competitive advantage to be ignored. The cultural imperialism of the West in the third world doesn't exist because we are forcing our ideas upon them, but because they desparately want what it produces.
The current conservative reactionary bulge will dissipate as their children engage in the complexity of public life and discourse, in the same way that conservative judges tend to drift to the left in the daily practise of considering complex issues. Like it or not, the real action is in science, technology, art, and intellectual expression. And while the bulk of conservatives may be content to merely consume the products culture produces, the most ambitious amongst them will want to participate. The admission price for participation is a serious consideration of other ideas--culture does not reproduce asexually. The alternative is decline, irrelevance, and even domination by those willing to make the effort. It has ever been thus, and I see nothing that would prevent this from continuing.
The only question is whether the new cultural elite will emerge from the ranks of the reactionaries through recruitment and subversion, or whether America will come to dance to someone else's tune. But simple biological reproduction is pointless if cultural fitness (including the capacity to practice scientfic research) is compromised. If six of your seven children die because they cannot feed themselves, you're still going to die out.
