Incidentally, I know that several labs have performed experiments in which fruit flies were effectively divided into two separate species in only around a dozen generations. I don't know if there were genetic differences to back it up or only reproductive isolation. I've also heard about someone who managed to get his E. coli to evolve into something demonstrably no longer the same as E. coli, but I don't know anything about that or where to find details. Does anyone have a link, or abstract, or something on the subject? —Alorael, who would like to believe that education correlates negatively with rejection of evolution. Education definitely correlates with lower numbers of offspring. It is therefore quite possible that the theory of evolution is evolutionarily unfavorable, and the causal links are absolutely ironclad. Posts: 14579 | Registered: Saturday, December 1 2001 08:00 |

Warning in advance: Long 1. INFINITE. IF an infinitesimal chance is spread over an infinite number of outcomes, there are still outcomes wherein the infinitesimal chance occurs! Please use logic. 2. How inaccurate can it be? And can you give me links to these studies? And the inaccuracy can shift either way, so you can't rely on that. 3. Yes, they have. Amphibians descended from fish (or fish-like creatures, at least) who at first could withstand being on land for periods from time, and it went from there. 4. You haven't argued against evolution. If anything, you argued for it there. 5. We aren't stupid. We can extrapolate from incomplete data. Just because the fossil tree isn't "complete", doesn't mean we can't disprove it. So we don't have every single species on it yet, but we can still draw lines of ancestry. 6. And we've had a billion years, and perhaps infinite chances across all of existence. You're right in that the chance is small, but it's not impossible. 8. So? We're complex, but we clearly exist! If this was pretty much random, as parts of evolution are, we could end up complex. If we were intelligently designed, why were me made to be so complex? 9. If you make enough prophesies, random chance will eventually ensure that one (or more, or less) will come true. This does not make you psychic, or divinely inspired. 10. Nicked from Kelandon's post: quote:Extra: So what if a real scientist said it? You shouldn't trust them just because they're scientists. You should analyze their evidence and the content of what they say.

Fred Hoyle has been famously wrong in the past, you know. :P The way I see it, there are really two kinds of people: those who find the anthropic principle satisfactory as an explanation for why the world is as we observe it to be, and those who don't. I don't think either group really has anything much to say to the other.

Yeah, Thuryl, I know. But I like where he got his ideas from. i.e. scientific observation, as opposed to the traditions and opinions of the scientific community. Granted, most of his conclusions have been since either debunked or dismissed by general consensus; however, I do firmly believe that we need more people questioning the scientific status quo. Worst case scenario, they're wrong, right? Salmon: :D -------------------- The Silent Assassin believes in questioning the status quo.

There's another term that people are butchering in this discussion, and I think it's worth discussing for a moment, because my Thermo class put it into serious perspective. It's the concept of "infinity." There's a huge conceptual difference between "extremely large but finite" (as in the size of the universe, the number of stars in the universe, the probable number of planets in the universe, the age of the universe, etc.) and "actually infinite." Given a number that is extremely large but finite, there is some limit to the craziness that can ensue. Given infinity, total chaos can break out. For example, it is commonly suggested that monkey typing randomly on typewriters would eventually produce the complete works of Shakespeare. There is a definite probability of hitting the proper keystrokes in the proper order. Neglecting capital letters and punctuation, but including spaces, we can say that there are twenty-seven possible options for each keystroke, and the complete text of Hamlet has well over 100,000 such keystrokes. The probability of getting 100,000 right keystrokes in a row is 1 in 26^100000, which is approximately 1 in 10^141,000. Now, if we take a billion monkeys at a billion typewriters, each typing at a hundred words per minute (which we can estimate as 600 keystrokes per minute or 10 per second), the number of keystrokes these monkeys would have typed in the age of the universe (approximately 14 billion years) is 4.4 * 10^27. Sadly, 10^27 pales in comparison to 10^141,000. The odds of these monkeys producing even a sizable fraction of Hamlet is unfathomably small. Let's try this again with just one monkey at just one typewriter and have him hunt and peck at a more feasible one word per minute (or one keystroke every ten seconds), but let's give the little monkey an infinite amount of time to work. The monkey will produce the complete works of Shakespeare, no question. It definitely will happen. We go from a probability of unimagineably small to a probably of 100% just like that. That's the power of infinity. So don't talk about things as infinite unless they actually are. EDIT: There is, also, a similar problem in really huge numbers. It's hard to remember, when we get up in the high orders of magnitude, that a billion is so much bigger than a million that it makes a million look like nothing. It's really hard to conceptualize "a million years." Common sense may revolt at the idea that evolution really can create such enormous complexity, but then common sense also can't really handle a million years, much less a billion. But again, this discussion isn't really a question of evidence.

There is a second part to the arguement on something happening that has a small probability of occuring. When you are looking for it among a large number of occurances, it is unlikely. But with evolution, the unlike occurance has to have occured in or for you to debate it. Now the chance of finding another world where it happened and occured in a time frame where we can see the result is probably low. There are only a finite number of planets that could have evolution occur on it and we currently can't detect those types of world yet. Posts: 4643 | Registered: Friday, February 10 2006 08:00 |

We had the question of carbon-14 dating with the Shroud of Turin debate last summer (?). Depending how it is done there can be a wide uncertainty in date calcultations. However in studies where a second dating system can be used in comparison like tree ring counting or comparison to artifacts at the site with known dates, it is fairly accurate.

I'm not a nuclear engineer or anything (*cough*), but I'm informed that C-14 dating has problems when samples are contaminated with organic material somehow. That is, you don't want to rub your hands all over a very thin rock if you want to use C-14 dating on it afterwards to determine the rock's age. Nor do you want to inject some bacteria all throughout the rock's interior. However, as Alo said, that's usually not a problem here with the standard date of the Earth, because the rocks usually aren't contaminated, and people don't use C-14 dating to go back that far anyway. Gah, when I do some planetary astrophysics later on, I'll be able to talk more about how we know that the Earth is as old as it is. I can say a little (a very little) about how we know the age of the universe, but not as much about the Earth.

quote:Well, you can't really carbon-date a rock in the first place. You'd use another kind of radioactive dating for that, like potassium-argon dating. So the reliability of carbon dating isn't really relevant when it comes to estimating things like the age of the Earth. But yes, "don't contaminate your samples" is a pretty good rule of thumb no matter what kind of test you're doing.

Piece of wood (or former living material), I meant. Dammit, I'm off today. In any case, I had a pretty good rant about the so-called lack of evidence for evolution here. Gaps in the fossil record are not evidence of anything. The very presence of order in the fossil record is almost indisputable proof that evolution is very, very real.

Good rule of thumb and problem with the test are entirely different. Unless it's nearly impossible to get an uncontaminated sample to date, I think it would be like claiming blood tests are useless because you could always get the wrong blood by accident. —Alorael, who has decided to take a physics approach and approximate the age of the Earth as infinite. It's close enough. Posts: 14579 | Registered: Saturday, December 1 2001 08:00 |

Literalism is indeed an extremely recent phenomenon. It might embarass you to learn that biblical scholars in the Middle Ages had it more correct than you: they not only regarded the Bible, being a human instrument for cataloguing the ineffable word of God, as fallible, but so fallible they inserted their own bits into it! 'Let he who is without sin cast the first stone' was written into a margin by a monk sometime before the end of the 12th century. Other marginalia are all over the book: someone writes down a clarification or a more concise quote in the margin, someone else likes it enough to put it in the text (putting it right in there yourself would be intolerable hubris, obviously), and bam, it's part of the Bible. The belief in Biblical inerrancy is a hilariously ignorant invention of the 19th century Protestant tradition. The very belief in inerrancy as a concept, I'd argue, is no more recent than the invention of the dageurrotype. Without photography, there's no grounds on which to construct the illusion of absolute precision (in this case, in sight), so people generally understand (if not in a scientific way) how rough and messy the world is deep down. ... One thing I'd like to add on the evolution discussion: part of what makes the understanding of abiogenesis so neat is that it allows us to put reasonable boundaries on the evolution of life. One of the bigger conditions is the presence and activity of iron meteorites in the general vincinity of a planet with liquid water - iron meteorites bear unusual quantities of phosphorous-based biomolecules, which explains one of the more inexplicable factors in abiogenesis and transforms life from a billion-to-one shot relying on a bolt of lightning to something more or less bound to happen under the right conditions. Basically, a planet like Earth needs a planet like Jupiter around, and it'll have life. That's not true of most solar systems, so we can rule out a lot of places while scouring the universe for other instances of life. This is part of what makes evolution so interesting: as a science, it produces useful predictions. Thanks to advancements in the decidedly anti-Genesis field of abiogenesis, we can say with better than 50% confidence that we know where life could evolve from scratch. Woo!

In physics terms, the body is actually remarkably simple. The vast majority of the human body, like the vast majority of the universe, comprises a few light elements: carbon, oxygen, and hydrogen. The only element found in abundance in life and not in the universe is phosphorous, which Schroedinger (from this board, not the physicist) did research providing for the genesis of.
