We see bacteria evolving new traits by mutation constantly, both in the lab and in nature. All that hoo-ha a few weeks ago about about Andrew Speaker was the result of Mycobacterium tuberculosis mutating over successive generations into a form which is resistant to antibiotics. Drug resistant staph evolved the exact same way. Creation of new traits by mutation isn't just an observed fact, it's the root cause of a growing medical crisis.
Now go back and tell Archonsod that. I'm rather tired of having to explain to evolutionists their own beliefs.[/quote]
So we're agreed beneficial mutations can happen? Good. It's a start.
At any rate, a minority trait in a species becoming a majority trait due to natural selection suddenly favoring the minority trait is evolution.
Which is why I try my best to use specific terms rather than more general terms like "evolution" - which is really a much too general term to be useful.
Let me take a wild guess: those specific terms are "microevolution" and "macroevolution", as if there's a meaningful difference between the two.
It's completely disingenuous to dismiss peppered moths because the variation was preexisting; how do you think the variation got there in the first place?
It doesn't take a genius to figure out that a creationist would believe that the creator would be able to create variation.
Except saying so explains nothing, is unproven, and most importantly for the purposes of this discussion, does nothing to support your claim that what happened to the peppered moths wasn't evolution.
Congratulations. You've managed to fit a strawman distortion of evolution and a misrepresentation of the time scales at which evolution operates into the same paragraph.
Maybe the time scales I'll let you have, I dunno about it being a strawman.
It seems our history remains unobservable.
See, this is how it works: if I accuse you of creating a strawman when describing something, "No I didn't!" does not constitute a rebuttal.
For the benefit of our viewing audience: you challenged another poster to provide an example of a fruit fly mutating into a butterfly. I'll do you one better: find me a quote (with citations, please) from an actual evolutionary biologist in an actual scientific journal that says that an individual from one living species can mutate into an individual from another living species, and I'll retract the strawman accusation.
How is it "questionable"? The fact that beneficial mutations are rare is already taken into account by evolutionary theory. You need a great number of generations of beneficial changes to accumulate, but they do happen (by your own admission, no less), and natural selection is biased in favor of beneficial mutations.
Well, a few questions:
1) Do the mutations really happen often enough, especially in animals with longer life spans?
Plainly they do, because evolution has been observed to occur. And before you accuse me of "begging the question" again, mutations were predicted by Darwinian theory before they were observed (or, technically, before Mendel's work was rediscovered). In other words, scientists didn't look at mutations and go, "Oh! Evolution must be happening!" They observed evolution first, and then discovered mutations later and said, "Ah ha! This is what's causing the changes we've observed."
But you probably want numbers. And here they are: according to two articles in the journal
Genetics (see citations below), the human genome undergoes between 64 and 175 mutations per generation, the vast majority of them in junk genes. The rate of mutations on active genes is between 1.5 and 3 per generation (this is all per individual).
2) Do the mutations necessarily create new information? After all, many "good" mutations may change or destroy traits, especially when the existing traits are undesirable in the current environment.
I actually haven't followed the information argument completely yet; I hope to find somebody who has a degree in information theory sometime so I can more thoroughly examine this and how it affects the debate.
I'll be blunt with you: Currently, creationists have been focusing not on whether a mutation is "good" or "bad," but rather on whether it creates new information.
Currently, that's what they believe - but I have my doubts. They claim that, while a "good" mutation may be possible, a mutation that increases information is not.
However, I do wonder if it's really true. From what I can tell, there's no law that really states that a gain of information is impossible, despite their claims. But I really do need to get in touch with an information theorist to make sure.
I'll save you the trouble. Creationist critiques of evolution based on information theory are predicated upon conflating two unrelated information theories which have nothing to do with one another. The result is entirely nonsense. Nonsense full of sixty-five cent words, but still nonsense.
The short version is, in Shannon information theory, which was developed within telecommunications, all the information that ever will exist in a signal exists at the beginning, and any noise on the line between the origin and destination can only destroy information. Kolmogorov-Chaitin (KC) information theory, on the other hand, talks about using entropy as a measure of information--the more entropy, the more information. Entropy is synonymous with randomness in KC theory, so random addition of noise
adds information. KC was developed in computer science but it can (and has) been applied to genetics.
What creationists will do is conflate them: measure the information based on KC, and then claim on the basis of the Shannon theory that information cannot be added to the system. This is, as I said above, absolute nonsense. You cannot conflate the two any more than you could conflate, say, physical inertia and anthropology in order to claim cultures never change.
3) Is there a way to test what happens over millions of years? IMHO, science is all about testing stuff - if we can't test our hypotheses somehow, we're on shaky ground. So far, our tests have been extremely limited by the large time scale required.
By that logic, astronomy isn't a science. A scientific theory, in order to be valid, must make testable predictions, but experimentation is not the only way to test predictions. There are many sciences where the primary means of testing a hypothesis is to look for evidence in the field; this is a perfectly legitimate way of conducting science. Radiometric dating, genetics, and the fossil record can and have tested evolutionary theory successfully many times, your unsupported objections to those methods withstanding.
3) Okay, we have an explanation of what
might have happened: Is there a way of proving it really happened that way?
In other words: We may have shown it's feasible, but that's not the same as showing it really happened.
First, showing it's feasible is half of constructing a valid hypothesis (and, incidentally, it's far more than what any Creationist has ever accomplished). Second, see above: there is a way of confirming it; in fact, it has been done so. Repeatedly.
Fortunately, we don't have to use our imaginations. The fossil record . . .
Calling it a "record" assumes the theory is true before we apply it. This is called "begging the question." How do we even know this is a record at all? Why not some other explanation, like the result of a catastrophe?
"It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts." --
Sherlock Holmes, "A Scandal in Bohemia"
Bzzt, wrong again. The fossil record was known before evolutionary theory; evolution was hypothesized in part to explain the otherwise unexplainable diversity of fossils. Evolution was tested repeatedly and borne out. Other explanations, and I cannot emphasize this enough,
failed. Flood geology (and let's be honest--when you hear "catastrophe", that's what almost everyone means) is wrong at nearly every turn--virtually every prediction it makes, if not every single one of them, has turned out to be wrong.
Here's a grab bag of questions for you:
1. If there was a Flood (or a "catastrophe", as you put it), why are animals from different biomes found in the same locations?
2. Continuing from that, why are animals found with other animals from the same biome in the same layer of rock, while animals from different biomes are in different layers?
3. Why are plants, which are not motile, found above animals, who presumably could have tried to run away?
4. Why are more mobile animals not found clustered at high points, in sheltered areas, wherever they might have run from a catastrophe, but instead distributed more or less randomly within their ranges?
5. Where are the physical signs of a catastrophe? Where are the enormous piles of debris on the continental shelves that would have been deposited by withdrawing floodwaters? Where's the impact crater from an asteroid or the transmuted elements from a nearby supernova?
6. Why did the catastrophe wipe out dinosaurs, giant amphibians, synapsid reptiles, and many giant mammals, but left some mammals who fill the exact same niches?
7. How did all the animals represented in the fossil record live at the same time without stripping the Earth clean of all plant life--going by known fossilization rates, the number of extant large animals would have been in the trillions had they all lived at the same time.
8. Why were there so many different animals adapted to the same niches living at the same time?
9. Why are stone and metal human artifacts, which should be at the bottom of the fossil record since they can't move on their own and don't float, universally at the top?
This is just what I came up with off the top of my head, and only covers paleobiology and a little bit of geology. Given a few hours, I could come up with a much longer list.
Science isn't about finding "the truth", let alone the "absolute truth".
Many people certainly treat it that way, insisting that other beliefs are ridiculous.
First, I am not responsible for the actions of others. Second, calling ridiculous beliefs ridiculous is not the same as claiming to know the absolute truth. I don't know the "absolute truth" about cars, but if a car salesman told me a rusted-out Trabant was a brand new Maserati, I wouldn't need to know the absolute truth to know he's:
A) Lying,

Delusional,
or
C) Unaware of what a Maserati actually looks like.
It's about trying to find the best possible explanation given current evidence.
Guess what? Different people believe different explanations better fit the evidence.
So what? Different people believe the moon landings were faked, the WTC was blown up by Donald Rumsfeld, the CIA is sending mind control signals through the cell phone network, and leprechauns are hiding under their beds. In fact, if you looked hard enough, you could probably find people who believe all four of those things.
This is why we have logic and the scientific method to begin with. Those are the filters by which beliefs can be sorted into "accurately describes reality" and "fantasy". If you can logically prove your beliefs, do so. Otherwise, admit you can't and we'll both get on with our lives--"Well, I believe..." or "Well, other people believe..." isn't a rebuttal.
I can't wait to hear how this is somehow worse than the theistic method
You'll have to continue to wait, as I'm not interested in what you call the "theistic method."
Strange, since you seem to be
practicing it.
Science has muscled religion out of its primary turf, which was to explain the natural world.
Yes, some religions try to explain the natural world - but I disagree that all religions do. In particular, I don't believe that was the goal of Christianity.
It may not have been the primary goal, but all Western religions do try to explain the everyday world as well as the supernatural one. Europeans had a coherent theory of the entire cosmos, and science came along and blew it all up.
And of course, if Christians aren't concerned with how Christianity describes the universe, why all this fuss and bother about evolution to begin with? Why does it matter if Christianity isn't trying to explain the natural world?
And Christianity has even screwed that up by adding the concept of Hell. And please, no yammering about forgiveness.
Very well, if you believe ignorance is bliss, feel free to ignore what our religion truly teaches.
Ignorance my...well, there's probably a profanity filter, but you can get the idea. I went through eight years of CCD (like Sunday school for Catholics) and was taught theology at a major Catholic university by a Ph.D.-holding Augustinian monk. I was a devout Catholic for the first 22 years of my life.
So yes, I know all about forgiveness, the Catholic and the Protestant variants both. And after all that, I still don't see how God can be benevolent and loving and merciful and forgiving--and then torture you forever if you don't do as he says.
And at any rate, your selective quoting, while cute, snipped my main point: religion is supposed to make death less terrifying, and then Christianity went and added something
even scarier to keep the plebes in line.
Strange, though, that I am not allowed to use strawmen, but you want to have the right to all the strawmen you want.
You'll kindly point out the strawman. Are you disputing Hell exists, and that Christians believe you'll go there if you don't follow the rules (believing in Jesus, incidentally, counts as a rule)?
The scientific viewpoint not only is consistent with the evidence and itself, it has actually produced improvements in human endeavors completely unmatched by religion or anything else.
So, the fact that you're amazed at technology is proof that men came from molecules? You're accomplishing nothing here but inflating your ego. Yes, we have great and wonderful technology. If you ask a Christian, they'll tell you that it's amazing how God's world works and how he has allowed us to create these wonderful things.
The point, which sailed so far over your head it's in orbit, is that the scientific method is demonstrably superior to any other for the purpose of describing the real world because it's the only one which has produced actual real-world results. It's not just a matter of opinion that the scientific viewpoint is better--it's a demonstrable fact. Atom bombs, poison gas, and germ warfare would be equally valid examples of real world results--I just picked positive ones because I liked them better.
First, "simple" is a common distortion of the principle of parsimony. Occam's Razor doesn't actually say "the simplest theory is right". It's the theory which accounts for all the evidence while introducing the fewest new terms.
Actually, for most Christian people, science is an exploration of God's world. It can in some ways be viewed as an extension of religion.
And yet you are insisting against all evidence and reason that evolution isn't true. Apparently some Christians see science as an exploration of God's world--until science finds something they don't like.
The arrogance, frankly, is astounding. I have an excuse--I think the whole idea of God is hogwash and make no bones about it. But you believe God gave you eyes and a brain and the power to analyze the evidence of His work--and then you ignore that evidence because it doesn't match the creation myths of bronze age desert nomads. If you revere God so much, then just who the hell are you to tell Him how to run His universe?
And from what I can tell, the idea of molecules turning into men introduces a lot of "terms" aka assumptions.
Funny how you seem to ignore the first part: "accounts for all the evidence". Biblical literalism doesn't, intelligent design does but tacks on God at the beginning for no good (or testable; ID is a classic example of an unfalsifiable hypothesis) reason.
And at any rate, those "assumptions" are merely that known chemical processes caused known substances to behave in known ways. The only really novel part, and the part scientists are still working on, is the order in which the processes happened and what outside factors were necessary. Compare this with creationism, which introduces an unproven, unprovable, enormously complex entity out of thin air, and either makes no testable predictions (intelligent design) or hilariously bad ones (Young-Earth creationism).
In other words, we know self-replicating molecules exist. We know evolution exists. We know how (mostly) how natural selection works. We know about as well as you can claim to know anything in science that we can get from molecules to men, and furthermore, no other explanation fits the data. Those "assumptions" you complain of that are filling the gaps are
predictions.
That said, it should be instantly obvious why God violates parsimony
I never claimed to believe "parsimony" as an unbreakable principle. Occam's Razor is a guide, not an absolute truth. It's possible for it to fail.
Then you may as well abandon any claim to be arguing logically and further discussion is pointless. Parsimony
is an unbreakable logical principle, or else it would be impossible to distinguish between hypotheses that explain the same data. Occam's Razor sometimes produces incorrect results, but the only way to know that has happened is if new data comes along.
and an unnecessary one, because cosmology, physics, chemistry, and biology together can explain the origin of the universe, life on Earth, and the complexity of living things without invoking Him.
I have yet to be convinced that cosmology, physics, chemistry, and biology together can explain all this without invoking new terms - in fact, a lot of new terms. I find assumptions all over the place. So I'm going to disagree with this.
You're free to hold whatever beliefs you like. But if you plan to present them as fact, which is what you're doing by participating in a logical discussion of them, then "I'm not convinced" or "I disagree" or "I don't think so" or "My mom told me you're wrong" or whatever else is a waste of perfectly good electrons.
Demonstrate that they're wrong, or concede the point.
The prerequisite elements for God to exist also exist, or at least existed at one time, adding an unknown number of extra terms.
It is believed that the exact number of prerequisites to be precisely zero. Indeed, the concept of requiring a prerequisite is nonsensical, since it requires the existence of time, and it is believed that God is not bounded by time.
God appeared out of nowhere by an unknown mechanism, adding at least one extra term.
Again, nonsensical, since it is believed that God is not bounded by time.
God has always existed and exists "just because". Unfortunately that exact same argument can be applied to a naturalistic universe, which has the not insignificant advantage in that the universe can be observed to exist.
I think we both agree that the universe exists. I'm not sure where you're trying to go with this argument.
You could have saved yourself a lot of typing by just saying "I'll take option three", in which God exists "just because" and promptly gets sliced out by parsimony. If we have to pick an uncaused cause, we go with the one which can be observed to exist, or at least inferred to exist by observable evidence (if you'd like to talk about universes budding off other universes as some cosmologists are wont to do).
And I should be kicking myself, because I missed something obvious the first time around: intelligent design introduces one extra term, because so far as I can gather (IDers are vague by necessity), they accept evolution happened, or appeared to have happened, and was only started or guided by an unknown (and unprovable, and unfalsifiable) designer. Young Earth Creationists, on the other hand, introduce
thousands of extra terms, maybe hundreds of thousands, because they have to explain away a century and a half of scientific evidence in every field from biology to geology to cosmology to chemistry to paleontology to nuclear physics to half a dozen others I can't think of off the top of my head in order for the cosmos to be 6000 years old. YECs are forced to choose between claiming virtually all of science is wrong, or invoking miracles.
Any variety of creationism between the two introduces more extra terms than ID and fewer than YEC. Thanks to the magic of parsimony, however, it's all equally wrong.
it also ignores that omnipotence is logically impossible
If you say so.
Mind if I make your job harder for you? Instead of defining omnipotence as infinite power, how about we just define it as enough power to control the known universe?
Why should I care how you define it? Since I already conceded (in a part of the sentence you snipped) that you don't need infinite power for creationism to work, omnipotence is irrelevant to the discussion--you may have noticed (even though you cut that out too) that I said that in a
parenthetical aside.
In all cases, you're adding at least one term besides God: you're assuming the universe has an "outside".
Well, the common counter to the "fine tuning" argument is that an infinite number of universes exists - which pretty much assumes the same thing.
Oh wow, you really got me there. I totally didn't realize there could be other universes.
In all cases, you're adding at least one term besides God: you're assuming the universe has an "outside". Some cosmologists do hypothesize this, but that is in no way proven, and it's not particularly helpful to you anyway, since they believe what is outside are other universes, and any interaction between universes, if possible at all, would be accompanied by pretty spectacular disruptions of space time.
Oh wait. I said
exactly that, and then explained
why it still doesn't help you.
I'm getting really tired of your selectively quoting me and then acting as if you've scored some rhetorical point by replying to an out-of-context stub. The first couple of times were questionable, but this was so blatant I actually laughed out loud when I saw it. If you can't defend your position against my actual arguments, you don't get to change them into something easier.
Creationists typically argue by attacking evolution, because with the exception of the Young-Earth biblical literalists, they concede that the empirical evidence for God's existence is zero.
Interesting. If what you say is true, then perhaps the young-earth biblical literalists may be onto something?
Since I'm an atheist, the only thing I think the Young-Earth creationists are onto is a supply of really great drugs.
That said, I'll give them credit for two things:
1. Unlike the intelligent design bozos ("Life is too complex to have evolved on its own. It must have had an unspecified intelligent designer!" *wink wink nudge nudge*), YECs are honest about their beliefs: "God did it, in six days, just like Genesis says."
2. Also unlike intelligent design proponents, YEC's have actually stuck their necks out and presented a real hypothesis. YEC is actually a better scientific hypothesis than ID, in the structural sense, because it makes predictions and is falsifiable. The predictions are all wrong and YEC is about as falsified as a hypothesis can get, but at least they tried. ID doesn't even get credit for being a hypothesis--it's proponents are so terrified of getting fed through the same shredder YECs went through that they've constructed a "theory" that couldn't pass muster in a game of Clue. Creationism has been a political movement, not a scientific one, since the end of the 19th century, but the IDers don't even make a token attempt at science. They dress up sophism in scientific language and try to sell it to people who don't know any better.
I suppose, to extend my car dealer analogy above, if a YEC is the first salesman, an IDer is a second salesman who comes up to me, puts his arm around my shoulders and says, "Listen, he's a good kid, and very enthusiastic, but sometimes he gets carried away,"--and then offers to sell me an invisible Bugatti.
Even if evolutionary theory collapsed tomorrow (Note: it won't), the default assumption isn't "an all powerful invisible man did it".
Actually, I do not believe there is a "default." The "default"s you present assumes that the "default" must be something observable. Although this rule about defaults may be in your own personal philosophy, it's not necessarily in mine.
Again, you're entitled to believe whatever you want, but "I do not believe" or "my personal philosophy says" don't cut it as logical rebuttals. If evolution collapsed, whatever theory took its place would still have to take into account all previous evidence, whatever new evidence collapsed evolution, and still avoid introducing unnecessary new terms. In a universe which has been observed, time and again, in every scientific field, to operate entirely by naturalistic principles, any replacement for evolution would be assumed to be naturalistic unless somebody actually managed to prove God exists.
The way I see it, a scientifically literate Christian has only three choices these days:
1. Become a Deist and hide in the corner behind the Strong Anthropic Principle
2. Deny reality
3. Accept that religious belief in based on faith, not reason, and get on with his life
Reason is based upon faith. Faith that the laws of physics won't change. Faith that logic and mathematics are sound. Faith that our axioms are a reasonable reflection of reality. Faith that our observations are reliable.
I believe that reason is built upon faith, and that they are not mutually exclusive.
Ah, the final page in the Creationist playbook: when all else fails, claim science relies just as much on faith as religion. Sadly for you, it doesn't. Yes, a materialist atheist has to say, at some point, "I believe certain things even though I can't arrive at those beliefs through reason alone"--Hume proved this almost 300 years ago. But so what? So do you. So does everyone--it's
useless to believe the laws of physics will change tomorrow because there's no possible way to react in advance to something like that, whereas it's
useful to believe they won't change, because you
can take actions (such as, say, eating food, or not stepping in front of a speeding train) which will be beneficial if they don't. As for assuming our observations are correct, again, what's the point of assuming otherwise? You can believe you're a brain floating in a tank all you want, but it's not going to stop the rent check from coming due every month.
Faith in God takes it to a whole other level. It is
not necessary to believe in God. And unlike the laws of physics, logic, and mathematics,
God cannot be observed to exist. By the same standard of evidence we apply to
everything else, God has been invented out of whole cloth by humans, because death is scary and the world is complicated and God fixes both those problems.
Jesus Himself draws a distinction between believing in Him and believing in the physical world; if it takes just as much faith to believe the sun will rise tomorrow as it does to believe in the Risen Christ, then what's so special about being a Christian?
