You have repeatedly failed to provide any mechanism to prevent the accumulation of so called "microevolutions" from leading to speciation ("macroevolution"). You have also failed to dispute any of the evidence I posted that includes empirical data showing observed speciation. People, including myself, know exactly what mechanisms and causes produce a new species. Don't project your ignorance of evolutionary biology on others.
Scientists can't even clearly agree on what a species is. Oh sure, there's that "every high school biology class" line... bull. I've already explained it, to which no refutation has been provided. So you're so-called "empirical data" is all fine and good, but since the scientists performing the research are also interpreting it under whatever light they want, it does me little "empirical" good. Seems like most of the scientific "evidence" I see proclaimed in the magazines has to be retracted later... see National Geographic articles on Archaeoraptor... "perhaps the greatest proof for evolution between species since Archaeopteryx..." Yeah. They had to issue a retraction later with an apology a year later when they found out it was a hoax. Why do people feel like they have to jump on these scant pieces of biological evidence for evolution that they can interpret under a favorable light... unless they're starving for those pieces that will support their view?
There isn't a mechanism preveventing accumulation of microevolutions from leading to speciations. I just don't see it when I look at the evidence, and I don't see the mechanism that causes microevolutions to amount to macroevolution on such a wide scale to explain the entire range of organisms. That's a jump that I don't think is supported scientifically. Finally, I don't believe that the world is 6,000 years old. The evidence indicates that the world is quite a bit older than that.
I'll dismiss your ad hominem attacks... but the rest of your ideas at least have a bit of credibility. I have no trouble with accepting evidence. I just don't see much that indicates that I came from a tree shrew. As far as accusing me of making strawmen arguments, I really don't think I have done so. Whether you accept evolutionism or creationism depends upon your philosophy of the origins of the universe. To me, the point is central. And if evolution doesn't include the discussion of origins, then it's an incomplete philosophy in my mind. The biological evidence that I've seen is lacking... I've tried to get all my biology teachers to show me evidence that things can evolve from one species to another and that life can come from nonliving matter and that somehow a quantum fluctuation of energy can produce the universe. I have yet to receive positive data. It'd be nice to not have to believe in a First Cause, because that inescapably leads me to a God to whom I'm morally accountable. And if I don't have to be morally accountable to a God, I'd rather not be. It'd be nice if life was meaningless and that every thought I could possibly have could be ultimately explained away as insignificant since it's the byproduct of random and chaotic chance, caused by an unguided and intelligent process. I have no problem with the idea of "inheritance with variation." This happens every day. I also have no problem with the idea that other species have formed as a result of mutations and genetic variation. I just think that the system fails when you try to universally bind it. Extrapolate backwards and think of the implications. When I was in kindergarten several years ago, they told me that the mechanism of evolution caused by a princess kissing a frog and turning it into a human was a fairy tale. In high school biology, they told me that the princess's name was Natural Selection and she kissed the frog while speaking words like "mutation" and "genetic variation," but that didn't make the fairy tale any more scientific. I love fairy tales as much as the next guy, but I must preserve my intellectual integrity.
And no, Moonbeam, I don't think it became a lost cause. It's obvious that you think in order for something to be "real" it has to be tangible, meaning that you can see it, feel it, experience it scientifically. If something transcends the universe, it would not be made of matter. It would transcend matter itself. I don't expect to persuade you, merely to explain my position and say that I disagree with you that what I pose has no basis in reality. For it makes sense that the cause of the universe must transcend the universe itself, else the universe is a self-caused existence. But to be a self-caused existence, the entity must be in act in order to bring about an effect. Thus, the problem. A being cannot bring about a cause without itself being in act. Thus you must have an uncaused cause. You're saying it's the universe, and I've shown why this cannot be. You're left with an intangible being who must exist in reality, yet in a different way than you can scientifically and empirically observe.
I think I'm done with this thread, though. If you want to flame me, just start a "xirtam is a loser" thread. I'll be more likely to read it, and you can feel more satisfied knowing that you've done all you can to show the world what an idiot I am for holding a position that contradicts the status quo. Anyway...
When the theory of evolution itself evolves into a scientific and rational theory, I'll accept it. But every presentation I have witnessed thus far has been unconvincing because it has left me with serious philosophical problems when I extrapolate to the origins. Where did it all start? That thought is central to me, and as Thomas has pointed out, evolution has failed to present a viable solution. Or better worded, the implications invoked by the philosophical implications of macroevolution as a universal mechanism explaining the formation of every organism is completely unrealistic, contradicting everything I observe about the nature of the way the world operates and striking against the value of intelligence itself. Science is based on cause-effect relationships to some degree, is it not? What about the cause of the universe? So quit playing the "Emperor's New Clothes" game with the universal idea of evolutionary theory. It's naked, bereft of undeniable scientific and philosophical proof.
Oh. And none of us were there. Why are we arguing about it? I don't share your faith, and you don't share mine, and messing around on an online board isn't going to change anybody's mind... so the only word I can come up with for this thread right now is...
nef.
I don't know about the rest of you, but I've about had a nef of this.
Good evening, gentlemen. (and baffled)
Edit: I don't disagree, Skyclad, that life can adapt to it's environment in favorable ways. I'm just at a loss for all this significant evidence everybody else seems to have for why all life in the universe came form... well... nothing. Seems to be almost universally accepted around here, but I'm kinda missing the proof. Or maybe I just missed that class where all the public school students were brainwashed with the "evolution" drug.
