      Far from "making every effort to obtain more evidence" regarding Hesperopithecus, Osborn actually ignored doubts about the nature of the tooth voiced as early as 1923, and no further work at the site was initiated until the Spring of 1925. Throughout the intervening period Osborn frequently used Nebraska Man as a 'stick' with which to beat Bryan in the popular press. In 1922 he jokingly (?) suggested that Nebraska Man might have been better named as Bryopithecus "after the most most distinguished Primate which the State of Nebraska has thus far produced." As late as May 1925 he wrote an article for The Forum, entitled "The Earth Speaks to Bryan" (a play on Job 12:8 - "Speak to the earth and it shall teach thee"), in which he asked: "What shall we do with the Nebraska tooth? ... Certainly we shall not banish this bit of Truth because it does not fit in with our preconceived notions and because at present it constitutes infinitesimal but irrefutable evidence that the man-ape wandered over from Asia into North America." Brave words, but not exactly well-judged. In late June Osborn was still listed amongst the eleven scientists "who will be called to testify in defense of John T. Scopes" (New York Times, June 26, 1925). When Bryan arrived in Dayton (July 7) he made it clear to reporters that he was looking forward to the opportunity of confronting Osborn and Nebraska Man head on. Yet where was Osborn? And where was Hesperopithecus? Certainly not in Dayton. Nor would they ever arrive. Although Osborn responded to Bryan's widely publicised jibes the very next day, with a full page defence of evolution in The New York Times, Nebraska Man was suddenly conspicuous by his absence. Likewise Osborn himself, far from attending the trial, stayed safe and sound in New York, without even supplying an affidavit of his testimony.
      The point? Once again, the evolution/creation issue is all politics, no substance.

It will certainly surprise him to find that he's argued that more complex forms are simply "more probable" as opposed to describing mechanisms by which they develop.

      "God" is not a default hypothesis. There is no default hypothesis. There is, however, a pretty solid line of explanation for life on earth based on so far observable laws. If you wish to fill any ignorance with "God did it," that's your bussiness, and there's certainly nothing wrong with that (indeed, most evolutionary scientists do so). But it's certainly not necessary in theory, and it certainly doesn't really explain anything.

How can you possibly judge the applicability of evolutionary theory, and the honesty of defenders of evolutionary theory, if you have a parody vision of what evolution is (and, I have to say, a vision that, despite your protestations, is easily identifiable as a creationist account).
      Mutation is simply ONE factor that builds up variation in a population. But mutation, even "good" mutation, is not how evolution or natural selection works. If all evolution was was the hope that good mutations would arise occasionally to adapt a species, then evolution would be highly implausible. But that's not it at all. In fact, population genetics studies have shown that, far from natural selection being limited by the rate of mutation, in practice natural selection actually serves to slow the rate of mutation down.
      Natural selection, first of all, works on interbreeding populations, not individuals (the advances of singular mutants wouldn't last very long in any given pool). Environmental conditions select ranges from a diverse population, and the next generation is then also diverse, but representively slanted in a particular direction of variation. That's how adpation generally works. It's not a process of simply waiting around for a mutation to break a logjam in development. It's not a process that waits for the right roll of the dice.

      Simple probability calculations give you an idea of how likely it is to have life arise. Since a basic tenet of science is to exclude non-naturalistic phenomena, for this discussion any divine intervention is excluded.

      As most of you know, proteins are formed in all living creatures by sequences of 20 amino acids. 19 of the 20 are "chiral", meaning they have a handedness to them. As an illustration, take a left and right glove. If they're vaguely anatomically correct, you can't superimpose one on the other without inverting one (they overlap if placed palm to palm, but not if placed in the proper orientation on top of each other). Many molecules are like this, they are chemically identical but not optically identical. The optical nature comes because the L arrangement (or stereoisomer or enantiomer) bends light one way, and the R bends light another way for any given molecule. Further data here.

      In all living creatures, plants, etc. proteins are formed from exclusively L forms of amino acids (again Glycine is non-chiral, it's so simple it has no handedness). Yet in natural circumstances outside already living things, there is no preference for L or R; lab experiments produce racemic (optically inactive, or equal amounts of L and R stereoisomers). So in a pre-biotic collection of chemicals, there is absolutely no reason to assume any preponderance of one chirality.

      Modern science has stated that fossilized bacteria are found in rocks 3.5x10^9 years old. Since nothing simpler has been found, it is assumed that bacteria arose first. The simplest bacteria known has over 300 different proteins in it, with an average length of 450 amino acids each. The average amount of glycine in proteins is 7.5%, so there are typically 416 chiral amino acids in a bacterial protein.

      Now we can calculate the probability of one protein arising with just the proper chirality. This of course completely ignores the much more complex sequence issue (which must be precise or folding and activation cannot occur). Since a growing peptide chain in an aqueous solution actually tends to dissociate, not to grow, we will also ignore the thermodynamics of chain growth - otherwise the spontaneous polymerization of amino acids into proteins would be excluded completely.

      So to get a series of 416 properly chiral amino acids (and ignoring the glycines), the odds are one in 2^416 of getting them all properly aligned. That's one in over 10^125. Wow, that's big... the known universe is 10^28 inches across. The universe is assumed to be 10^18 seconds old. The visible universe is figured to have 10^62 to 10^80 atoms; so using the high bound number you could form one protein a second per atom in the universe for the life of the universe, and still have only one in 10^27 odds that you'd get one protein somewhere with the right chirality.

      So what are the odds of life arising from non-life via protein assembly by purely random means? Essentially zero, on earth or any planet. There are those who say "but life is here so it's 1.0 on earth". Yes the odds are 1.0 on earth, but those odds include ALL possible methods of life arising; so to use the result as the conclusion you have to be willing to consider other models (including non-naturalistic) or you're not being honest, since the random arising model can easily be seen to be impossible.

    I had a population of simulated organisms competing in a shared 2d grid for food, which appeared in a pile at a random location when the old food was depleted. While the organism had basic looking/moving operations to rely on, invariably some would discover that with enough organisms, the food moves enough that you can survive by just looking around until the food is in your line of sight, and then jumping on it. My arbitrary decision to place the food randomly formed the basis for an *entire species* of organisms (which didn't fare too well when some got smarter).

    These same organisms used a stack to do their thinking. Looking and eating produced values, which could be used for simple branching. Out of sheer laziness, I designed the stack to allow infinite pops off an empty stack which would return false, and infinite pushes on a full stack which would discard the values. One memorable run produced a dominant species which relied on this stack behavior to implement COUNTING! It intentionally (well, purposefully) left crud on the stack in a main loop, relying on the filled-stack behavior to detect a certain number of iterations. The stacksize and the arena size happened to be comparable, and this is how it determined when to turn.

The most common tombstone enscription was "i was not, i was, i am not, i have no more desires". Out of this "hell" people decided to believe in an afterlife because their real lives were so terrible.

    Nonsense.

    Obviously, you know virtually nothing about history and even less about Christianity to say this.

    Claim 1: That Christianity didn't gain more than a small foothold until after the fall of the Roman empire. This is simply not true. In fact, Christianity seems to have been a force to reckon with as early as 115 in parts of the empire - witness the letter of Pliny the Younger (in Egypt) asking how to do deal with it. In fact, Starting in the early 300s, Christianity was THE official religion of the empire. However, the Western Empire didn't fall until (generally accepted date) 476CE and the Eastern Empire persisted in one form or another until almost 1500.

    Claim 2: That Christians invented their religion in response to suffering, to develop a fantasy afterlife with no suffering. Here, you display a severe lack of Knowledge of the New Testament. In fact, the early Christians were severely persecuted. We know that at least three of the major early leaders were executed by the authorities before 70 (Peter, Paul and James) and we know that the leaders were again and again imprisioned for their faith. We have numerous books that seem to be written by and for people undergoing serious persecution - e.g. Revelation. (Also, consider Matthew 24). And there are about a million side references in Paul to persevering through persecution. In fact, that seems to be one of the major recurring themes of the New Testament. It was not until the end of the third century that being a Christian was even LEGAL - it was largely illegal because worshiping "King Jesus" was seen, across the empire, as a threat to the imperial cult and to the emperor.

    Claim 3: that all these "rediculous" (sic) laws came up out of a desire to avoid hell. In fact, the specific "laws" you mention are specifically denied in the New Testament. For example:

    Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day.
    No responsible theologian would claim that you were required to go to church on Sundays, although most would say that it is a good idea.

    Look: You are trying to judge a religious faith - which is ultimately a set of propositions - by the actions of relatively few of its adherents. This is not fair - ultimately the propositions can stand or fall on their own. And the main proposition is the fact of Jesus' resurrection. I have found that, if you actually approach this issue with rigor, you are forced to the conclusion that Jesus did rise from the dead (the best efforts of certain "scholars" notwithstanding.) I was not raised in the church, I came to that conclusion as an adult. Why don't you stop focusing on peripheral issues and instead look at the core of the faith?

    Years ago I read an intriguing Omni article that talked about Dragons and hydrogen. This is the best reference online I could find...


    So long as we're here, we'll pass along the best theory we ever heard about the possibility of actual dragons, which, as we recall, was in an old copy of Omni magazine:

    Dragons were creatures with hugely overdeveloped stomachs. Since stomachs produce hydrochloric acid & this acid breaks down into hydrogen gas, this meant that dragons were essentially giant gas bags.

    Well, dragons couldn't just go & burp out excess gas the way we do - if the hydrogen ignited, they'd go up like the Hindenburg. So dragons ignited & burnt the gas as they vented it, in a controlled fashion, which was seen by terrified townsfolk as fire breathing.

    From this also came the myth that swords plunged into a dragon melted. It's the natural reaction of metal to concentrated hydrochloric acid. It's also the reason there's so few dragon remains: The acid in the stomach at death ate the flesh up, or perhaps at death the remaining gas ignited & burned it up. In any case, dragons would have had very light, fragile bones, very light bodies, very weakly developed muscles, so, minus the gas, there just wasn't a lot to a dragon. There are very few old bird remains for the same reason, & dragons must have been even more fragile.

    For these reasons also, their liking for bare, craggy cliffs. If it wasn't bare before he got there, he'd burn up everything around it, just burping normally. And since, aside from their breath (the worst cases of bad breath for all time), they had very few defenses, isolated places were important to them.

    Presumably a reptile, they would be sluggish in the morning & probably heavier than air as well, having lost some hydrogen overnight. So it's likely dragons would vent some of their remaining hydrogen to warm themselves the morning & get their systems going. This could also account for their prevalence in northern Europe, which is otherwise too cold for large reptiles.

    Wings would have helped circulate warmed air in those drafty caves, but otherwise would not have been large or powerful. They would not have been feathered. They would have been more like bat wings, even though bats are mammals. Dragon wings were used primarily for steering, not propulsion & were presumably adequate for a dragon's needs.

    As to a dragon's liking for young virgin females, I cannot say. Since so much of what dragons were reputed to be matches the giant stomach gas bag theory, it's hard to write off virgin feasts as just another myth. It might well be that young girls had some particular odor that interested dragons, or it might be that young boys put up more of a struggle. It could be that dragons needed a lot of meat protein to keep themselves afloat & that small furry mammals (dogs, cats, etc.) were too small or the fur got in the way of digestion, and it could be that full grown humans were just too heavy to carry off. Leaving undefended small girls as a dragon's first choice at mealtime. People who are clever with physics & math could answer this question: What volume of hydrogen gas is needed to carry away a kicking & screaming 70 pound person? If this is how dragons got fed, then we presume they could generate the necessary additional hydrogen within a very few seconds, so a dragon with prey would be a very bloated affair.

    I'm confronted with the absurdity of someone who can't spell "ridiculous" or "believe" or "claim," or use the apostrophe correctly, quoting as his authoritative source John Lennon, and who moreover couldn't recognize a clearly anti-Christian troll and responded to it with diatribe against a religion he apparently knows nothing about, promising me that someday I will "wake up". Your original post seemed to imply that you thought Christians uneducated. I wonder - who sounds uneducated in this conversation?

    I'm working on a Masters in Theological Studies, and in a year expect to be working on my PhD at University of Virginia (not exactly a charm school), and have debated Christianity vs. Atheism with the best on the Net and off. I went through two years of debating anyone and everyone on the net on the historical merits of Christianity, and at the end of it came to the conclusion that there was not one valid historical argument against Christianity and that there were many, many reasons to believe it was true.

    Let me respond to your Lennonism with a relevant quote:

    For what I received I passed on to you as of first importance : that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Peter,[2] and then to the Twelve. After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep. Then he appeared to James, then to all the apostles, 8and last of all he appeared to me also, as to one abnormally born. 1Cor 15:3ff.
    What are your relevant historical reasons for assuming that this (indisputably authentic) utterance is a lie? And when will you be getting your high school diploma?

    Or differing nutrient and hormonal exposure when they shared the womb...

    You can, of course,come up with things that could be slightly different. For example, Rebecca was born thirty minutes sooner, and her head had to push open the cervix, so maybe she's just a little bit brain damaged? However, the babies differed only by three ounces of weight (one was 5lbs. 9oz., the other wass 5lbs. 12oz.) have been together ever since, etc. I think that any naturalistic differences you claim are really just post-hoc rationalizations designed to preserve a failed concept of human nature.

  59. Genetic Programming by A55M0NKEY · · Score: 1
    I wrote this program for shits and giggles that takes the alphabet of [a-zA-Z0-9] + '"~;[]{}-> Things I found:

    1) at first all my high scoring programs were very short.

    2) once adding points for length, all my working programs ( populations circa 1000 ) started with the '#' character.

    So I did a $prog =~ s/\#//g; before eval ( $prog ); from now on and all the # cheaters died. Then I tried to teach it to add. I set three variables that would be visible in scope to the programs I was evalling. my ( $input_a, $input_b, $output ) = ( 3, 5, 0 ); Then I scored the programs higher if the program changed the values of any of the three variables. I added code to increase the score of a program further if the values of any of the three variables depended on the initial values of the inputs ( by changing the initial values and re-evalling )

    Things I found:

    1) a grep of my perl program beasties for input_a and friends found zilch.

    2) my perl beasties were still very short

    So I added score for length, and I started doing some genetic engineering by splicing in '$input_a' '$input_b', and '$output' at the '#' crosspoints randomly for every child program.

    Things I found:

    1) Many perl beasties grepped for $input_a and pals

    2) None of my beasties changed the values of any of output, and inputs a and b

    Then I got bored and had a sickpack of beer and soon didn't care anymore. But something's moving in my basement and I don't have any pets....

    The program made random perl programs ( beasties ) from the above alphabet and bred them. Programs were given a score of 0 if they failed to compile using eval. They were given a positive score if they compiled. The highest scoring half of the perl programs were mated with the other programs randomly. The lowest scorers were deleted. During mating, the ascii strings representing the programs were crossed at crosspoints which were places where both programs were '#'. The offspring were cloned from that point on from a randomly selected parent's ASCII characters until a point was reached where both parents ASCII code was '#' again.

    words like eval, open, opendir, link, unlink, exec, and system were removed before evaluations.
