xpccx writes "Here is a very interesting article at MSNBC by Arthur Caplan, Ph.D., director of the Center for Bioethics at the University of Pennsylvania in Philadelphia. He states that "The genome reveals, indisputably and beyond any serious doubt, that Darwin was right - mankind evolved over a long period of time from primitive animal ancestors. Our genes show that scientific creationism cannot be true." This is arguable but should spark quite a debate." Even Kansas agrees.

Proof in science, and false science (Score:3)
That said, many of these lab reports used single or multiple "observations" to prove the thing being tested. That is, the assumption was made by the student that the appearance of the phenomenon was proof of the truth of the hypothesis. It was amazing how many people came in believing this nonesense.
Scientific experimentation never ever proves anything. It can disprove only (the proof side involves checking on all possible permutations of things, and that is not possible in times long compared to the age of the universe). Hence, what one needs to investigate are the predictions of a theory. This was the other thing that students got wrong. A theory is a hypothesis, an idea, that makes predictions. If the theory does not make testable predictions, it is not a scientific theory. If you cannot objectively test an idea's predictions, how can you possibly assess the validity of the idea?
"Scientific Creationism" makes no predictions. It is an attempt to codify a system of beliefs into a particular language. As such, it is not a scientific theory. If it made testable predictions (say structural predictions on the form of proteins in similar organisms) then it would be testable and therefore falsafiable.
And that is the difference. Evolution, or rather, evolution-like theories, which make specific predictions are testable and falsafiable. If you find sufficient evidence that can convince a skeptical group of unbiased investigators that there is a disparity between the prediction and the observation, then you may rightly claim that the theory (or one area/mechanism) is false. The flip side of this is that if you find no such evidence, then your results are consistent with the theories predictions. One of the other more important aspects is that even if one particular mechanism in the theory is found not to be correct, it may not invalidate the entire theory, rather just that mechanism. From this, people build on existing theories with new theories that can explain the observations, and make more predictions. So even if Darwin's orginal mechanisms are not quite right, the latest proposed ones fit the data even better than before, and make testable predictions that are being looked at as we speak.
Compare this to a biblical dogma derived "theory" which makes no testable predictions, provides no method of falsification, and generally does not allow room for disagreement. "Scientific Creationism" is not science (as it fails the testable hypothesis portion of the requirement for a theory). It is dogma. In a new set of clothes. Do not be fooled.

Scientific Creationism? What is it? (Score:5)
Which makes me wonder, what is this "scientific creationism" thing? Creationism without an creator? Or just another abuse o fthe word scientific?
Note that "scientific" does not mean "true". A theory can be scientific and false, or unscientific and true.
Interesting Editorial (Score:5)
Dr. Caplan does an excellent job of pontificating his viewpoint - that Darwin was right and "all those who thump their bible and say there is no proof" are wrong; he very clearly and concisely tells us that the proof of evolution is in our genes, and that every scientist worth his/her salt agrees that there is no other explanation other than Darwinian evolution.
However, not once does he lay out the proof of which he speaks. Whether Dr. Caplan's viewpoint is correct or not, this article is nothing more than an emotionally persuasive argument with no scientific credibility whatsoever. It's well and good to say that there is undeniable evidence of Darwinian evolution in the human genome - that's what most people have been hoping for, searching for; but if such a sweeping statement is going to be made, especially to the rather scientifically ignorant masses that MSNBC and other mainstream media outlets serve, then it must be backed up by the actual evidence in question, lest we fall into the trap of believing a Big Lie that simply gets repeated enough times.
Science is detailed observation of the natural world, and this article offers no such observations, only emotionalism. I would greatly enjoy reading a scientific paper on this subject.
The fact that this is a bad argument... (Score:3)
...against scientific creationism does not mean that scientific creationism is, in fact, right.
Note that Caplan (who has said much more interesting things than this: see, for instance, his interview on cloning on the Charlie Rose Show) may not be actually saying as much as some people are assuming he's saying. He specifically states that the Human Genome Project results disprove "scientific creationism," not creationism. Since "scientific creationsim" refers to a specific movement, it is entirely possible they have made statements and predictions which are contradicted by this new evidence. He goes on, however, to imply that the new evidence proves something more broad about creationism in general, which is clearly false.
I believe that the best arguments against scientific creationism are not scientific arguments, but moral and religious arguments. I will offer two below: one theological and one practical.
My theological argument is based on the fact that I believe in a God of truth. If God created the world 4,000 years ago or so, then he created it as if it had existed for billions of years and as if life evolved slowly over time. Thus he is a God of deceit. Since it is more important to me that God be truth than that He created the universe a few thousand years ago, I choose to believe that those who believe the Bible says the universe was created (relatively) recently are wrong. Note that, even if I chose to believe that God was deliberately deceiving me, I would still have to decide whether I should accept that deception as what He wants me to believe.
When I go to the Bible to see what it says, I find that the statements there are vague and contradictory. It is not at all clear that the 7-day creation story is to be taken literally. There are other places where creation appears to take place over a long period of time.
I also note that my belief that God is truth is not unambigously supported in the Bible. While there are several places where "God is truth" is clearly indicated, Jeremiah just as clearly says that he saw God lie to other prophets in order to trick Ahab into an ill-starred battle. The belief on which I found this theological argument is a belief and nothing more. But I think it is preferable to the alternative.
We have seen other times when religious communities believed just as strongly as the creationists that the Bible said things which in the end proved to be untrue. An obvious example was the geocentrism on which many scientists were persecuted during the Copernican revolution and beyond. Today we do not believe that the Bible says the earth is the center of the universe, and it clearly is not. I suspect someday we will see virtually universal agreement that the Bible does not say anything one way or the other about evolution or about Darwinism. And I suspect we will find the current debate as quaint and silly as we now view the torture and excommunication of those who suggested the sun was at the center of our solar system.
This historical perspective leads me to my second argument against scientific creationism: the practical argument.
As a practical matter, it seems like the goal of Christians should be to generally encourage belief in God and to avoid things which discourage belief. I believe this is the central tenet of evangelism, that we should emulate the life of Christ, the Evangelist.
Observing history, it is clear to me that the Copernican revolution did some damage to belief in Western Europe not because Copernicus sought to sow disbelief but because the assumption of the church was that he would. By tying belief to a doctrine which was not in fact clearly indicated by scripture, the church ensured that (when the evidence came in supporting the heliocentric model) the community of Christianity was damaged far beyond what it would have been had it not taken such a dogmatic stand.
It seems to me that, as a practical matter, we Christians have a moral obligation to avoid taking a stand on evolution which will be as damaging to our community as was anti-Copernican dogma.
And it should be made clear this is, in fact, what most Christians believe. The vocal minority of scientific creationists may get the most press. But surveys show that many, if not most, people who believe in God (again a majority) also believe in evolution. Remember that Darwin was trained as a minister and never believed he was attacking the Bible or belief in God.
Indeed, the head of the public effort to decode the human genome, Francis Collins, is very open about his Christianity and his belief that genomics do not in any way threaten God. Here is a quote from him:

Evolution is a fact. Species change from one form to another over time. Speciation has been observed at least twice, both in the laboratory and in the wild. No one disputes that evolution occurs.
There is a theory about how evolution occurs: It is called "The Theory of Evolution by Natural Selection". That theory has a great deal of support. There is another theory out there. It is called "The Theory of Evolution through Acquired Characteristics." Otherwise known as Lamarkian Evolution. Lamarkian evolution does NOT have any support at all, and the theory is not favored by anybody now.
Get it?
1) Evolution is an observed fact.
2) Scientists have come up with theories to explain the fact of evolution.
3) The Theory of Evolution through Natural Selection is the currently supported theory.
4) The Theory of Evolution through Acquired Characterists is not favored anymore.
5) Both theories described evolution. Both theories were about the fact that species change over time. One theory proved useful, one did not.
I hope that was more clear this time. As you can see, I am right.

I will say that evolution is one of the better explanations we have today, but phlogiston [infoplease.com] was once the best explanation we had for combustion. Evolution is not falsifiable -- even if it were, no amount of science can disprove a mystical, revealed truth.
I guess I could also bring Nietzsche and Wittgenstein's views of "science as a religion, flawed like all the others" into the fray, but I fear I will catch enough heat for this.
But what's the point of this article? (Score:4)
No matter what side of the issue you're on, this article offered nothing to decide the matter. It didn't even look like it was trying to convince a non-believer, just a bluff to try to sound superior to "those who thump their bibles." (I just did a Google search on Caplan, it seems like that's his standard level of dialogue when he's censoring or chastizing a Christian point of view.) Why would a neutral person think that mapping the human genome decides the matter definitively? If it does, Caplan didn't even come close to showing that. And this clown actually gets paid to teach students?

Hawking-Hartle No-Boundary Universe (Score:3)
This brief summary [pbs.org] describes Hawking & Hartle's proposal for a no-boundary universe, in which the issue of what happened before the big bang is taken care of with some neat mathematics. The bottom line is that the progression of time from the big bang as a "beginning" is just something we perceive from within the universe - looked at from an appropriate conceptual/mathematical perspective, there's no problem.
In this model, what happened before the big bang is a little analogous to the problem of "where does all the water go that falls off the edge of the horizon?" was when we believed the earth was flat. The imagined problem disappeared once we comprehended the larger structure.

Darwin VS God (Score:5)
I took a Darwin class in college and debated the issue Darwin VS God, where I interviewed a Catholic priest as a primary source, as well, as read through some Church documents. From what I gathered and remember, the Church states, God began the process of creating humans (The presence of a soul in humans separates man/woman from animals). In other words, he didn't say "Hocus Pocus, I am going to pull Adam and Eve from my magical hat." The "process of creation" could be something quite similar to Darwin's evolution theory. The Biblical tale of Adam and Eve should be interpreted as "folklore". So this story doesn't fully address nor fulfill "Creation vs. Evolution" debate in the present day. God and Darwin can be both correct.

Some background and few remarks on evolution... (Score:4)
Account for my English it's my second language. Don't pick on words.
Some background:
First, I think we all agree that solid science relies on facts (or, emperical data) and comes up with a plausible hypothesis to try to explain their relationships (like, cause and effect, interdependence etc) and once the hypothesis is shown to predict relyably the outcome of a certain process, the law is stated with a theory to support it (that is, a 'law' simply states how things shoud work - 'unsupported body falls until it meets the ground' and a 'theory' explains the mechanism). So, we have the distinction between 'facts', 'hypothesis', 'law' and 'theory' layed out here.
Clear minded science, obviously, should look at evidence first and form a theory basing on that.
'Facts', in turn, is something which can be observed and repeated.
So, on to the topic: here's how the evolution theory roughly goes:
Correct me if I'm wrong on this outline (well that was a rough one anyway).
An interesting observation: there is no factual prove of any of these steps having taken place . (the obligatory disclaimer: read before you flame).
Well here were few suspicions about the theory of evolution which so many hold as fact today. I tried to show that every step is taken on faith and is not proven scientifically (e.g. with facts) but instead explained away with more theories or ignored.
The suggestion is to rather have no theory at all than a lousy one, which is based solely on naturalistic world view of most of scientific community and s.c. 'public'. The fact that 'we are here after all' does not prove evolution yet.
I invite discussion.

It's still not proven (Score:3)
The very fact that we share proteins and cellular structures in common with bacteria dictates that we must share genes in common with them. We've long known, for example, that mouse biochemistry is very similar to our own. Logically, we must share a great majority of genes with them. That the tools used to make similar structures are similar in no way denies divine creation of these things.
We have long known that we would share much in common with other creatures. I don't think any scientific creationist has ever denied this. Why should God use more complex tools to create life when so much of it is reusable? Perhaps as a software developer, I see the inherent need for reuse of code whenever possible that others might not. All this shows is that evolution would have had to do less work to get to the point that complex life has gotten to. It is in no way the smoking gun that proves the theory.
Let us remember what so many in the scientific establishment attempt to deny: evolution is nothing but a theory. It is a good one, and it is the only one that makes sense if you posit the lack of existance of a creating force. However the fanatical willingness to overlook flaws in the model is just as much a matter of religious (atheist) dogma as some of the twisted logic of some of its opponents.
The problem comes when one puts their faith in the belief that there is no God. Rather than accept the possibility that they are wrong and respect the beliefs of others, dedicated evolutionists will attempt to push their doctrine as fact, much as this author has done.
In truth, these people will hold their doctrine of evolution to less standards of proof than they would hold a religious man's beliefs. Though as religious man is treated a fool for believing in a being that he has never observed, evolution, which has never been observed, is not treated as rigorously. In fact, when confronted with gaps in the fossil records, evolutionists countered with the puncuated equilibrium theory. This theory holds that the reason for the gaps is that evolution suddenly happens across all species for a short period of time and then stops for millions of years. Brilliant! Now, if we cannot observe evolution it is not disproven because it may never happen in our lifetimes, or, indeed, in the lifetime of all of human civilization.
This gleeful "slam dunk" article that revels in taunting an evolutionist philosophical rivals is one of the worst examples of athiest zealotry that I've seen. In his rush to say, "I told you so," the author misses the simple fact that a divine creator could've used common tools in the creation of life just as easily as random luck. This is no proof, and this antagonistic little chestbeating is not worthy to be called news. Until we can see evolution definitively happen in a higher life form, we cannot accept the theory of evolution as proven no matter what other incidental evidence encourages support of the theory.
(Incidentally, I'm a theistic evolutionist. I believe very strongly that evolution is true, but that it was guided by a divine plan. However, as someone who does not assume that there is no God, I have no turned a blind eye to flaws in evolutionist doctine. I believe that they will be plugged one day, but I am not willing to outright dismiss the idea that evolution is the only possibility.)
