You have a skewed idea of the definition of "predict" if you think one needs to predict the past. The reason the weather long ago is better known than the weather tomorrow is that the long ago has already happened. Scientists can tell what the Earth's climate was like long ago by seeing the evidence of its effects. When meteorologists predict the weather, they're merely taking what they have and extrapolating educated guesses.

Firstly, nobody who follows the theory of the origin of the species thinks they they are the controlling factor in that origin, so your claims they they're thinking they are the superior being is incorrect.

You seem to imply that because it's a theory, that it's necessarily wrong. The theory of relativity is also considered a theory, but it has stood up to much experimentation. "Theory" means "not yet proven" but should not be extrapolated to mean incorrect. It's more appropriate to say that theories are incomplete.

There are two points here. First, nobody on Earth can explain why gravitation works. Nobody knows the reason why massive bodies attract one another. To say, however, that this means we can't discuss gravitation in a meaningful way is just silly. We discuss gravity by examining its effects on our universe. We discuss evolution the same way.
Second, I don't personally know anybody who claims that life "came about by chance", and this is the classic straw man argument about evolutionary theory. All this statement demonstrates is that you haven't actually read or studied the theory, because your statement demonstrates gross misunderstanding of the mechanisms of evolution. I won't go into the gory details unless you wish me to do so, but suffice it to say you're badly misinterpreting evolutionary theory, and it ruins your argument.

Refer to my statements above about incomplete understanding, and about the "evolution=chance" argument. I will add here that not being able to create life in a lab has no bearing to this discussion, because it assumes that because we haven't done it yet, we never will, and because we don't understand it now, we never can. A mere one hundred years ago, nobody could build a heavier-than-air flying machine, or a computer, or a television, or any of a thousand other things. We learn. It's what we do best.

And that's precisely what's wrong with Darwin's theories. He observed certain phenomena in nature, and based on what he knew about artificial selection, he speculated that similar processes must occur naturally.
However, he didn't know and didn't have the means to discover the mechanisms underlying the hypothesized natural selection. That's why his theory is not scientific -- it's a pure speculation, but it doesn't provide mechanisms, which can be falsified experimentally -- something essential to modern science.

On the one hand, it's undeniable that if people with concrete, measurable genetic defects were not allowed to reproduce, then the occurence of these defects in future generations would be reduced and perhaps even eliminated.
Actually, no ... and the reason is simple. Most genetic diseases are the result of one of three things: receiving multiple copies of recessive traits that individually have survival benefits (sickle cell anemia, for instance), receiving recently broken copies of genes/chromosomes (Down's syndrome), or receiving broken genes that do not generally manifest until after typical reproductive years (genetically linked hypertension or genetically enhanced risk of breast cancer, for example). There is no evolutionary pressure on any of these types of genetic abnormalities that will make them go away: it is well known that recessive traits are nearly impossible to "breed out" of a population, because that requires that no one with the trait be allowed to reproduce; recently broken gentic material will continue to arise, as long as we reproduce, even if we could start out with a hypothetical "perfect genome"; and traits that don't reduce reproductive potential can not be acted on directly by evolutionary pressure.
No, in the long term, there is no chance that "genetic diseases" can be suppressed by preventing those that have them from reproducing. You can also think of it this way: we've been breeding now, under evolutionary pressure, for nearly 2million years, something like 100,000 generations, and genetic diseases are just as prevalent today as they were in the past; since many of them are fatal without treatments that have only been available for one or two generations, by your logic, shouldn't they have been bred out of the population long ago?

Yes, certain things like sickle-cell anemia (which brings resistance to malaria), as I recall) are harder to judge in absolute terms as "defects" or "benefits" - it doesn't matter.

Yes, we twiddle the details all the time, but big theories like the heliocentric solar system, gravity, atomic theory, evolution, etc. seem to stand the test of time.

Actually, there are some legitimate nitpicks here. Hanson (1958) and Kuhn (1962) argued that empirical observations are 'theory-laden' and that scientists see the world through paradigmatic world views, respectively. Which is to say that one's theory influences what one observes or interprets his or her observations. These philosophers were not just skeptics -- they were influenced by the gestalt and 'new look' psychological theories of visual perception.
Some of the best evidence for the subjectivity of even empirical observations comes from cases where seemingly sober scientists 'saw' things that their theories told them were there but which actually do not exist. Some quotes:
"During the seventeenth century, when their research was guided by one or another effluvium theory, electricians repeatedly saw chaff particles revound from, or fall off, the electrified bodies that had attracted them. At least that is what seventeenth-century observers said they saw, and we have no more reason to doubt their reports of perception than our own." (p. 117, Kuhn, T. S. (1996). The structure of scientific revolutions. (3rd Ed.) Chicago: The University of Chicago Press.)
"In 1903 Rene Blondlot claimed to have discovered a new kind of ray, instances of which were recorded and investigated by a large number of eminent French scientists. Outside France interest in N-rays waned when it was reported by the American physicist R. W. Wood that during a visit to Blondlot's laboratory he surreptitiously removed from the apparatus an essential prism. Despite the secret sabotage of his equipment, Blondlot still reported seeing the effects of the N-rays." (p. 120 of Bird, A. (2000). Thomas Kuhn. Princeton, NJ: Princeton University Press.)
"There have been cases in the history of science in which skilled scientists of the highest repute have 'seen' or 'verified', through observation and experiment, the prediction of some hypothesis, even though this prediction subsequently turned out not to correspond to reality and could not be reproduced by other observers. For example, Sir William Herschel (1738-1822), discoverer of the planet Uranus, the father of John Herschel and the most famous astronomer of the eighteenth century, was able with the powerful telescopes he manufactured to resolve into individual stars several nebulae that had previously appeared to be milky luminous patches in the sky. In the mid 1780s, he conjectured that all nebulae were composed of individual stars so that none were made of a luminous fluid. In 1790 he did observe a nebula that he was forced to interpret as a central star surrounded by a cloud of luminous fluid. In the interim period, however, Herschel claimed to resolve into individual stars both the Orion and Andromeda nebulae. In fact, though, Orion is a gaseous cloud containing a continuous distribution of matter, not just individual stars, while Andromeda is a galaxy of stars." (p. 10 of Cushing, J. T. (1997).

Although one might take my analogy to mean that Genesis is simply a work of art, I hold it to be transcendent to art. The attempt to force the painting to function as wallpaper seems a ghastly perversion of its actual worth. To expect Genesis to serve as a comprehensive description of creation, when that expectation is fundamentally denied by the book itself, is a ghastly perversion of its actual worth.

"Behe's colossal mistake is that, in rejecting these possibilities, he concludes that no Darwinian solution remains. But one does. It is this: An irreducibly complex system can be built gradually by adding parts that, while initially just advantageous, become-because of later changes-essential. The logic is very simple. Some part (A) initially does some job (and not very well, perhaps). Another part (B) later gets added because it helps A. This new part isn't essential, it merely improves things. But later on, A (or something else) may change in such a way that B now becomes indispensable. This process continues as further parts get folded into the system. And at the end of the day, many parts may all be required."
"The point is there's no guarantee that improvements will remain mere improvements. Indeed because later changes build on previous ones, there's every reason to think that earlier refinements might become necessary. The transformation of air bladders into lungs that allowed animals to breathe atmospheric oxygen was initially just advantageous: such beasts could explore open niches-like dry land-that were unavailable to their lung-less peers. But as evolution built on this adaptation (modifying limbs for walking, for instance), we grew thoroughly terrestrial and lungs, consequently, are no longer luxuries-they are essential. The punch-line is, I think, obvious: although this process is thoroughly Darwinian, we are often left with a system that is irreducibly complex. I'm afraid there's no room for compromise here: Behe's key claim that all the components of an irreducibly complex system 'have to be there from the beginning' is dead wrong."

Analogies can be used to explain science, but analogies cannot be used to draw conclusions or falsify scientific theories. Yet Behe commits this fallacy throughout his book.

True scientists question theories to find what's right. They take a hypothesis, test it against real-world results, see if it fits, and keep going until they get a hypothesis which _does_ match the real world as accurately as possible. If two people come up with opposing hypotheses which both fit the data, they'll argue about why they're each right, and in the end science will either (a) find further data to prove one or the other, or (b) find a way to merge them into a single entity.
Creationists OTOH start not with a hypothesis but what they think they know as a fact, ie. creation by God in 6 days, in the year 4004BC. As a creationist, this is the only possible outcome - if you believe in creation, it is impossible for you to believe that any evolution has occurred, by definition. So if there's data which disproves creation, the only way ahead is to (a) ignore or (b) attempt to discredit that data (or the person providing the data), which creationists have done throughout the 20th century.
We don't believe in evolution bcos "we're here so it must be true", we believe in it bcos it fits the data gathered from all sciences, ie. a world several billion years old, geology, fossils, and the range of body forms for creatures. Certainly there's gaps in it, but there's less gaps than in the Biblical creation theory, and every development in biology has supported evolution and cast further doubt on creationism.

A good way to get one of these is to zap it with UV or some other mutagen to induce a random point mutation (change in one nucleotide). This could alter the gene product just enough to make it non-functional at high temperatures, making the organism more sensitive to the environment than it was in the wild type form. This new sensitivity is a gain in function for the organism. It might not be beneficial, but it is a demonstrable gain of ability for the organism.
Another example would be oncogenes, which aren't always active, but can be activated via mutations, causing cancer.

Try to see if a population of organisms can "discover" the line of poetry "This is the way the world ends, not with a bang but a whimper." You'll note that there are 29 possible choices for each letter (26 letters + commas + periods + spaces). And in the above string, there are a total of 62 characters. So, to present the power of evolutionary theory, Dawkins imagines a population of agents randomly initialized to 62 characters. One of these might be:
"jkdzcn43asdf lkjasdfhaokjshfla ksdhfoiuykjahs, asdasd. sdfsdf."
you can imagine that each agent reproduces unequally based upon how well it does given the utility function -- in this case, the utility function returns an integer from 0 to 62, where 0 indicates no letters match and 62 represents a perfect match for the entire sentence. Each generation is exposed to mutation in the Dawkins example, though one could easily add crossover (which implies sexual reproduction) and inversion. The code is roughly:
1) initialize X agents in a population to random strings of length 62
2) write a function where each agent reproduces unequally based upon how well it optimizes the utility function given above. This choice matters, but not a lot. For our purposes, imagine that every organism below some threshold X has a 10% chance per time period of dying outright. And every organism above this threshold has a 10% chance of replicating.
3) After step 2 (which represents one tick on the clock), expose each organism to genetic operators. Mutation is simple: pick a % chance Y (where Y is small; if it is too large, you lose information too quickly) for each character in an agent (or gene if you prefer) to mutate to a random character. Thus, if Y is equal to
4) repeat steps 2 and 3 until you see equilibration of your population.
After a bit, it should be obvious to you that most of your agents will approach the correct sentence, whatever their starting values. Further, not all of the organisms in a population will ever be at the "right" outcome, given mutation in step 3.
So what does this tell us? Simple math helps out. To optimize the utility function above is simple, and we know this because we can compute the number of steps it would take to optimize it. Couple of points:
1) the function Dawkins uses (outlined above) is separable. No character / gene depends upon any other character / gene to determine the utility of its expression. This is huge. Think about it until you get a smile on your face. For real organisms, this is NOT the case (i.e., genes are non-separable). This is why evaluating the results of the genome project is ugly. If we had, for example, one gene acting alone to determine intelligence, it would be easy to detect / modify. Sadly, multiple genes acting in concert determine intelligence, and modifying one gene in the set changes the value for the entire set.
2) The number of steps needed to optimize the above function is 29 * 62 = 1798, which is an extraordinarily TINY search space.
3) If the characters / genes were non-separable, as they are in real organisms, things are quite different. Worst case is completely non-separable -- i.e., every character depends upon the value of every other character for evaluation under the utility function. In this case, you have 29^62 (where the '^' represents the exponent function). Obviously, this is a freaking HUGE number. Even low levels of non-separability (e.g., pairs of genes that depend upon each other to produce a trait) generate huge search spaces.
The fraud of Dawkins is thus simple. He proposes a set of operators that
define his theory of evolution -- unequal reproduction, crossover, mutation,
and inversion, and illustrates their efficacy (i.e., the "success" of the
theory) on a simple toy problem. The ugliness, however, is that solving
separable problems, which is the class of utility functions Dawkins uses
to "test" his theory, is trivial. Everything / anything works well on them,
and there is no real way for any given theory to fail on this class of
utility functions. The other, more interesting class, which has the
property of being an analog to REAL ORGANISMS WITH REAL GENES is when the
utility functions are non-separable, and the theory / set of operators
Dawkins proposes has NO success searching the spaces induced by this type of
utility function.

The dice for complex life are loaded somehow, or we don't understand the
mechanisms of genetics. The existence of these regulator genes simply begs

None of this, of course, displaces evolution as the best fit for the

To explain away the Creationists' argument, not only does a candidate mechanism such as this have to be found, but there must be a detailed explanation of which changes occurred, to which species, in what order, and how the resulting creatures could survive in either land or water.
The evolutionists still have a lot of work to do. If a shrimp loses legs and gills, and absorbs oxygen through the skin, can it still survive in water long enough to go ashore?
Whenever I get in a discussion with evolutionist types, they often respond with an attitude of over-skepticism. Stuff like, "I won't even consider this belief system without absolute proof!" Are those same people now criticizing Creationists for not bowing before this non-proof?

First, I don't see how making an animal lose a pair of limbs helps for gene therapy. That aside, nobody's claiming that this is the final piece of evidence, only that it's another nail in the creationist coffin. A common argument of theirs has been that entire organs & limbs can't simply appear or disappear through simple genetic changes. Well, genetically, scientists have made that happen, and showed that on that score creationists are wrong.

just cannot migrate to land, no matter how many legs it has.
Walruses. Penguins. Hermit crabs. Mudskippers. Etc. I know they're evolved (oops), but these are all animals that in their daily lives, apparently, do the impossible. With all these animals doing it every day, is it so impossible to believe that it might have happened at some point in the past, with or without legs? And who said legs were a requirement to move to land?

We're also seeking all the factual evidence we can to mount atop the mountains of it we already have. While it's difficult to reach through the millenia of the fossil record, we're working on it, based on facts, as we go along.
Now I'd like to require the same factual rigor of you. Please provide factual proof of a God's existence and his influence in placing living things on this planet. I want a candidate mechanism and a detailed explanation of what changes occurred and how. Again, we'd like facts and not bible quotations please.

This comment is pointless, as there's no reason a shrimp would have to either lose legs or gills to come ashore. There are gilled fish that can survive for a time ashore as well as gill-less marine mammals, as are there many legless and multilegged animals that can do so.
Are those same people now criticizing Creationists for not bowing before this

The difference is that our evidence is based on a preponderance of facts, developed through repeatable experiment, and leading us in a direction toward a theory that has withstood almost 150 years of scientific scrutiny, despite concerted effort from your camp. Yours is based on mythology, as written by a group of middle-eastern tribesmen under Roman rule between 100 & 500AD.

Theoligy and science (Score:4, Interesting)
First, just so everyone knows where I'm comming from, I was raised a creationist. And in the past I've been a devote creationist that would try to "debate" with others to promote my point of view -- thinking that if you believed in evolution you were an atheist. However, as I have matured (a little bit, not much), I can say that my own beliefs have evolved.
I don't understand anymore this animosity that Christians and Evolutionist have between each other -- this fierce compitition. When I read the Genesis account (first few chapters) and get all the imagery out of my head that I was raised with (the presuppositions so to speak) I see a very general story that is not intended to be a science text book. I think details are purposely omitted because the point of the book is not for us to know exactly how everything came into being, but to understand that a supernatural being created it and the relationship that we have to this being.
Christians that are threatened by evolution don't have a true concept of the omnipotence of an all powerfull God (or Yahweh, Jehovah, Cosmic Spirit, or whatever name you attach). Think about it, if you had unlimited processing power and data, you could drop thousands of pieces of paper from a plane at 10K feet and know exactly where each paper would land. Moreover, now assume that you can control all of the variables (wind speed/direction, ordering of papers, turbulance, etc) -- then you would be able to cause each of these papers to land where you wish them to land. Now, back up to the Big Band (or whatever started the Universe). Assuming that all energy and matter that exists in the universe today was involved in the Big Bang (to my knowlege science has not found any exceptions to the law of conservation of energy and matter). Now lets assume there's an all powerful being that causes this Bang and sets up all the variables to Its liking. This being, in theory, could then foreordain the entire universe as we know it today in a single instance at the time of the Big Bang. To the Creationist, all of this appears to be the work of God, Its creation. However, to the Evolutionist, all of this appears to be the work of chance (just a question for thought, but is anything really random? Or do we just label events as random when they become too computationally complex?). Add to this that God is outside of time (exists in all of time at all instances at once) and you realize that there's more the the Genesis account than meets the eye! I guess what I'm saying is that I don't think that science and the Bible are mutually exclusive.
Now, on the flip side, I don't understand why some scientists are so bent on disproving the Bible and slamming Christians -- almost a fear of Judeo-Christian beliefs (well...maybe I do, there have been and still are some pretty crummy people that call themselves Christans). The Bible was written by over 40 authors from 3 continents and from various backgrounds (kings, prophets, common folk, political prisioners, etc) and it was written over a span of 1500 years! What a wealth of knowlege and wisdom it contains. Some claim that it contains a meta-narrative of a God trying to reconcile a relationship with mankind. If nothing else it contains history and 1500 years of culture and living experiance. How you choose to read it is where faith comes into the picture. It's just a shame that there are all of these debates about the Bible and Science, but very few people actually read the Bible (including Christians) even though it is classic literature and a great read once you understand the context/culture/timeline in which it was written.

I hear some primitive tribespeople fear having their pictures taken because they think the camera steals a bit of their soul. So if they don't see a camera, they don't get excited. And when their backwards beliefs are not challenged, they live peaceful, harmless lives. In other words, don't show creationists cameras. Get it?
After all, Al Qaeda is nothing more than a Muslim Fundamentalist backlash against the "decadent West." New ideas are dangerous. Progress is disturbing to some people. Some do not accept new, and better ideas. They instead cling to old, crazy ones and get very defensive about it. They frame it in absolutes, that evolution goes against God, for example. Evolution does not go against God. Science is not allied against religion. Any forward-thinking religious person can incorporate evolution into their world-view without evolution challenging their beliefs. It will, in fact, enrich their understanding of the world, deepen the mystery of life by making more clear the complexity of it all, and therefore, eventually, reaffirm their belief in God. But all of this assumes an open mind. Unfortunately, there are a lot of closed ones.
Don't show creationists cameras!

Right now their numbers are too large and the voraciousness of their passion too disturbing in the USA to be considered harmless. They are quite harmful, to the education and intelligence of all of our children. Give it time, many years, and they will fade away into history. Someday, decades from now, creationism will sound almost cute and harmless, like we laugh at the Spanish Inquisition in Monty Python skits.
Until then, they are just a massive pain in the ass. Please, ignore them! Here on Slashdot, and in the rest of your life. Your intentions are good in trying to challenge them in honest debate, but please, just walk away from them. There is no winning, just lots of hot air for you to inhale.

The whole argument is stupid, anyhow. It's based on a mistaken belief that one must cling to a questionable interpretation of the Bible as a matter of faith. Has anyone noticed that only Creationists tie Evolution, Geology, and Atheism together? Those who research Evolution do not insist that one must be an atheist if one believes that evolution rather than recent creation is a better explanation for the development of life on Earth. Those who teach and research modern geology do not insist that one must be an atheist if one believes that geologic processes rather than recent creation is a better explanation for the current geology of Earth.
However, since Creationists fallaciously tie acceptance of modern geology and evolutionary theory to disbelief that God created the Earth, and therefore disbelief in God (i.e., atheism), it has become a matter of faith to oppose evolutionary theory and modern geology as a false, atheistic (and thus, probably diabolic) doctrine by any and all means. If you don't believe me, go read articles and web sites by Creationists that are targetted toward Christians, as opposed to the general public.
To my mind, it is all very pointless because there is no contradiction between evolution and God; who are they to say how God created the universe and life? How can they know that evolution and geological processes are not just more tools in God's toolbox? They can't know, and they who presume to know how God created the universe or to put limits on the methods God used in creation are both small-minded and arrogant beyond belief!
To my mind, the power and grandeur of God is elevated, and not diminished by evolution and geology. To achieve His unknown goals, He started out at least 15 billion years ago with the Big Bang, and designed the entire process of star formation, planet formation, geological processes, evolution, etc! That's a lot bigger than POOF! The Earth was wished into existance a mere 6000-8000 years ago, complete with fake fossils and fake geology.

Cyanobacteria came into existance to take advantage of the freshly broken down minerals, the abundant CO2 and the precipitating water. Aerobic bacteria came to be to take advantage of the abundance of oxygen and other material floating around in the soup and in the air.

There have even been numerous observations of speciation (an invidual of one species creating offspring of another species).

What is commonly refered to as "The Theory of Evolution" is just a collection of ideas about how and why evolution happen, such as natural selection, punctuated equilibrium, etc. No serious scientist disputes the fact that evolution occurs, the only dispute is over how it occurs.
Creationism is also, admitted by the professors of said doctrine, to also be a theory.
Creationism is NOT a theory. It doesn't hold up in experiments testing its predictions. It is at best a highly improbably hypothesis.
What makes it right for the kids to arbitrarily learn only one of these theories. It seems that under the First Amendment, that both theories should be taught, and let everyone decide for themselves.
What makes it right is that one of these "theories" is religious in nature and basis, and the other isn't. Since SCOTUS (that is, the Supreme Court Of The United States) has ruled that the First Amendment decrees a separation of church and state, the religious "theory" obviously does not belong in a publicly funded school.
This seems to be yet another instance of the government telling us what we should think.
This is in fact just the opposite. It is the government preventing itself from telling us to think a certain way on religious grounds. The government isn't preventing you from sending your children to a religous private school, or from teaching them creationism yourself. But it is preventing the teaching of ideas that favor one religion over another being supported by public funds.

So is all of science. In science you observe the world and come up with an explanation (a theory). Then you see how far that takes you. Theories let you understand how things work and are used to build things. For example, there is a theory of elecricity, which makes it possible for you to read this post.
An important property of a real theory that in principle you can present evidence to falsify it. What evidence would you present to falsify creationism?
It seems that under the First Amendment, that both theories should be taught, and let everyone decide for themselves.
First Amendment gives you the right to speak for creationims, but it does not give you the right to force others to listen.
Having said that, I wish they would teach both in science classrooms. Just explain the evidence for both: genetics, fossils, geology for evolution and some old book written by ancient men for creationism. Then let the kids sort it out.

You seem to be unaware that scientists have been growing insects with extra body segments, legs sprouting from their heads, etc., for decades now. All the quoted text means is that they have found the built-in mechanism for managing this, not that they have suddenly discovered that it is possible.
Thank you for showing the lurkers how bad creationists are about twisting everything around in hopes of discrediting science, and how pathetic that spin control is when you dissect it.

I would expect that most people who think clearly about these things wind up "neodarwinists." The point is to come up with an explanation for "all the other processes of life" and we would be commiting classicly flawed logic if we used the-things-to-be-explained as the basis of the explanation.
If evolution depended on the existence of complex processes of life to work, it would be useless and likely wrong.
As it turns out, however, you can explain it all (including reto-viruses, co-operation, and even the first post trolls) as a simple consequnce of random mutation and natural selection.
Your statement is akin to fearing that "a lot of physisists are neonewtonist--they think everything can be explained in terms of a few types of forces acting on a few types of particles." In many cases you want to look at the higher consequences just to keep from swamping in the details, but you shouldn't slip into confusing consequences with causes.

Second, nobody said you need to grow a fully formed stomach when there was none before. I've already has this conversation on
Stop thinking stomach, and start thinking proto-organs, or even single cells that exist symbiotically within another organism. Ameobas don't have stomachs, they have, I dunno, specialised cell groupings that secrete a 'digestive' chemical that extracts nutrients from any external piece of whatever that happens to float by. This is not a "chicken/egg" problem, so stop coming at it from that angle. As for those 999,999 generations of nonworking "stomachs": that took a whole 2 or 3 days of debugging in a pond somewhere to get the right one, way back 600 million yrs ago. After that it was just code tweaking.
What is it with people and evolution, that they can't imagine some slimy chemical mud that has "intent" - in so far as it gravitates toward another chemical gradient (food) - being alive?
Imagine Q or Rod Serling standing next to a small puddle explaining this to you OK? Here we have a pool of chemical x that naturally moves towards chemical y. In a few moments, this chemical soup will undergo a common reaction involving common chemicals. It will become "alive". It will contain a few simple organic compounds that, given some quiet time to themselves, will intermingle and maybe even begin to replicate - the ablity to harvest nearby chemical compounds and assemble them in a *near* mirror image. Hell some of those compunds can be from other "proto-organisms" and we already have predator and prey evolving. Neat huh?
Asking how stomachs and eyeballs formed while imagining them as real functioning eyeballs and assholes is like asking how you get a fully formed modern man equipped with a cell-phone -- from a club-swinging neanderthal. You don't. Because the neanderthal never picked up a club with the express purpose of building a cell-phone. If he did, he would have quickly found that he was without the proper environment to create one, let alone NEED one.
So too, did early life not set out to outfit itself with a stomach, but instead went for the more practical "I just found a new way to eat my food by actively enveloping it instead of passively absorbing it from my environment -- COOL"
what follows sounds like a linux bash but i cant be bothered to clean it up, take what you want. I'm getting tired....
And your comp sci analogy doesnt work either, as building the Linux kernel that way is akin in biological complexity to building a chamaeleon or something from scratch. Try creating a kernel that can "eat", "defend" and "replicate"(sounds like windoze). Your Linux/chaemaleon is wasting time trying to be 10 different species/server tasks. Whereas a flatworm just does what it needs to divide and move on. Maybe you should write the comp sci equiv of a flatworm (haha windoze again), then maybe your flatworm kernel will be able to withstand random mutations?

Creationists don't believe in science. They may find it interesting and accurate in some places, but to believe in creationist is believe that science often relys on erroneous, politically biased information to form incorrect conclusions even after extended periods of time. That's they don't believe science reliably works - they don't believe in science.
Yes, it's unfair to describe creationists as stupid. Mostly they're working from postulates that are alien to scientists.

Intelligent conversation and discussion can only occur when you throw away all your stereotypes before stepping up to the table. Some
philosopher talked about this once, but basically, you are supposed to try your best to approach the situation without making any
assumption about the person/people with whom are you discussing, how it will benefit you, etc.
I believe quite the opposite. Because of science and its ability to give us solid facts, it's wrong to give all views equal credence at the starting line in a scientific discussion. Of course the idea appeals to us because most of us believe in democracy, equality, etc, and in a purely philosophical question like ideas of right & wrong, aesthetics, etc, you'd be in the right. Science, however, is by no means democratic, by which I mean that any idea MUST match known facts. Discussions on evolution are thus NOT philosophical in nature, because they seek to project facts to formulate an idea about the past. The theory being contested is that animals, including ourselves, developed over time through natural selection. Whether this is true, for a scientist, can only be demonstrated and proven with facts. Creationists OTOH choose to use science when it suits them and discard it when it contravenes their religious beliefs.
This leads me to another argument of yours, that creationists are in the majority. That may be so, but the facts do not rely upon consensus, only on veracity through experimentation. Also, the silly pretense that creationism isn't a religious belief is belied by the fact that it relies on a sort of de novo, deus ex machina placement of life on the planet by a higher power, an inherently religious phenomenon. One could argue in response as Richard Dawkins does, that the idea of the development of man over millenia from more basic organisms is infinitely more awe-inspiring than being plopped here by the almighty about 6000 years ago.
Creationism is to some worthy of ridicule, and understandably so. It's a relic of a time when humans looked up at the sky and thought the stars spoke to them, when we didn't understand why the ground shook or the sun turned dark in mid-day. While I don't agree with bashing people's religious beliefs, when they want to use those beliefs to create public policy, or mandate the passing of those beliefs on in schools, in science classes no less, it's only my duty as a scientist and someone true to simple fact to oppose such stupidity, here and anywhere else I see it.
