About a year ago, If I remember correctly, I got into a conversation with someone regarding the Multiple Universe theory. I asked him why he considered it scientific. Evidence, he said. Like what?, I asked. The math, he said.
The math. I disengaged at that point. I was dealing with a zealot and didnt want to get into his spiraling down into fractal wrongness. But now that I think about it, I may have been harsh in my assessment. He was just regurgitating the views of prominent theoretical physicists. In this new phase of science that began with Einstein, evidence is not as important as mathematical beauty. Paul Dirac once famously said that ''it is more important to have beauty in one's equations than to have them fit experiment.'' Therefore, if you postulate a multiple universe in an equation youre creating, and have that equation turn out to be beautiful, then you are assured that multiple universe is possible -- never mind that you postulated its existence in the first place -- and therefore multiple universes is a legitimate scientific theory and not science fiction. Beauty is truth; truth beauty. That's all you need to know.
The same is true of Darwin's theory. It is such a simple, elegant theory, and as such has proven seductive that natural and social scientists have been mesmerized into applying it in all aspects of life. Darwin's theory isnt survival of the fittest. That's a tautology. Of course the fittest survive. (Sure, sometimes the luckiest survive, but one couldnt build a scientific theory out of 'survival of the luckiest'.) Darwin's theory says that random mutations occur all the time in living organisms and then nature selects, through a blind, unintelligent process, without goals or purpose, who gets to pass on their genes. See how this process is not applicable to politics, culture, ideas, society in general? But the theory is so friggin beautiful one can't resist it. In biology teacher blackshama's words in a comment in a post over at Philippine Commentary, it has great explanatory power.
And the evidence? This is what Richard Dawkins has to say about the evidence:
He did it again with this interview with Bill Moyers. The crime scene analogy is a favorite among advocates of intelligent design, and here he is, using the same thing, and in a wrong way too. Darwin's theory does not allow a murderer. It assumes that no intelligent agency is responsible for the crime. Darwin's theory only allows accident as a cause of death in the crime scene. In fact, Darwin's theory will say no crime was committed at all.
A year ago, I said that it was impossible to model Darwin's theory using computers. That's because you always come back to the programmer, that is, you always come back to an intelligent agent who programmed the whole thing, who determine who gets to survive and all that. METHINKS IT IS LIKE A WEASEL all over again. Here is a critique of the attempts so far from the Panspermia site. Dawkins's little foray into computers is included.
However, with the powerful supercomputers we have nowadays, we can at least try to mimic Darwinian evolution using computers. Here's how it can be done:
1) Take large set of characters and arrange them in random fashion. For example: 2882482u9hedi1whei1uei1uer1urei1urncuio3`ur`2ru03r93949124012488*(&*^(*&)&(^&)(*YUOHHFTR%&&RFft78&*t88t87T78tT7t78tGyIkbh H+_Ouiuu009)8u0098u()890898292-3-83-234-14-2`3-48(***_(*)_+U(I)*_*_(++_*_**_*I_(NBOUHGTUKUJUGPUU@##$DRTFYT(*?>><L<L>O}{{

You need a very, very, very long string. This represents nature before life emerged.
2) Next, you will need an algorithm to simulate natural selection. This algorithm will have to be randomly generated and must not have any human intervention in it. The selection process will have to be 'meaningless' to the humans and can vary in complexity. For example, you can run find-and-replace sequences wherein the strings to be searched for are random strings and will be replaced by random strings. For example, in one instance, the program looks for the string 4995HUJijpp^55$ IF they are followed by the string 29820*(&)&BY*O, if in turn this occurs after the 679th character of a 1 MB worth of string is a G, etc... and replace it by the string iooo-012489*(*(_)=+, or it could be a simple algorithm like replace all A with G.
3) Next, you will need to reboot the system at random intervals and the machine will try to run the program created by steps 1) and 2) above. This represents the input of energy that we postulate happened to the primordial soup. If nothing happens, it will repeat processes 1), 2), and 3). The system does this until a self-replicating string emerges, or more accurately, until steps 1) and 2) comes up with a recognizable program to step 3) and results in a string that replicates. This represents the common ancestor.
4) The system then introduces random errors based on some random algorithm in the replicating string such that at random intervals the copies of the replicant will not be exactly the same as the "common ancestor." The 'errors' will just be one bit at a time.
5) An algorithm similar to step 2) is then applied to the whole thing again. We will not need step 3) anymore as it is assumed that the replicators can take energy from the existing environment.
With any luck, using ultra-powerful supercomputers, we'll end up with the same biodiversity from a common ancestor that Darwin's theory predicts using blind processes.

And the evidence? This is what Richard Dawkins has to say about the evidence:
MOYERS: Is evolution a theory, not a fact?Dr. Dawkins has this penchant for picking the most inappropriate analogy for his theory. He did this in the third chapter of The Blind Watchmaker when he tried to demonstrate natural selection by writing a program wherein the phrase METHINKS IT IS LIKE A WEASEL emerges from a random string. He was able to do it in 40 or so generations, which is pretty impressive, except that the target phrase is already programmed into the system. The system knew what it was looking for. In trying to illustrate Darwin's theory, he inadvertently illustrated some form of intelligent design theory.
DAWKINS: Evolution has been observed. It's just that it hasn't been observed while it's happening.
MOYERS: What do you mean it's been observed.
DAWKINS: The consequences of... It is rather like a detective coming on a murder after the scene. And you… the detective hasn't actually seen the murder take place, of course. But what you do see is a massive clue. Now, any detective…
MOYERS: Circumstantial evidence.
DAWKINS: Circumstantial evidence, but masses of circumstantial evidence. Huge quantities of circumstantial evidence. It might as well be spelled out in words of English. Evolution is true. I mean it's as circumstantial as that, but it's as true as that.
He did it again with this interview with Bill Moyers. The crime scene analogy is a favorite among advocates of intelligent design, and here he is, using the same thing, and in a wrong way too.
