Anyway, someone I know brought up the lack of "in-betweeners" as an argument against evolution. As in, why isn't there half-ape half-human creatures walking around today? (I'm pretty sure the theory says we didn't evolve from apes, but rather we had a common ancestor, but that's beside the point.)
This has been discussed recently on these forums. Go here to see how a whole bunch of us responded to this question.

Just because a bunch of people agree. Does that make it a fact?
If so there are millions of competent observers who have confirmed repeatedly that there is a God.
I think you missed the "independent" part: nobody on the face of the planet received a "witness" of God without first having access to somebody else's witness. Have you noticed how infrequently we evolutionists cite On the Origin of Species? This is because we have obtained the same answer that Darwin came to by independent (and, frankly, better) means.

Re: My Response to Subbie's Challenge
Buckfan, you claim to be a scientist. I have decided to disbelieve you in this claim for the following reasons:
1. When asked to define what you think evolution is, you respond with a series of things scientists believe. You should know very well that "theory" does not equal "beliefs of scientists" but "a well-supported model that explains a given phenomenon."
2. You have included abiogenesis a part of the theory of evolution, when abiogenesis is not requisite for the theory of evolution to have effect. If abiogenesis were disproven, the theory of evolution wouldn't suffer at all.
3. You have included big bang theory as part of the theory of evolution, when big bang theory isn't even remotely associated with the theory of evolution.
4. You have included "belief in a pre-existent universe" as part of the theory of evolution, when a pre-existent universe isn't even remotely associated with the theory of evolution.

I do believe that it demonstrates that as a certifiable 'creo' I at least have a grasp of both the key points of the debate and some of the science that underlies it.
I personally believe that it demonstrates nothing of the sort. I think it shows very clearly and precisely the exact same mentality that prompted subbie to start this very thread. You have cast evolution as the lump sum of the sciences that defy a biblical universe model, just as laypersons lump all prehistoric animals under the name "dinosaur," when, in fact "evolution" and "dinosaur" have very specific and restricted meanings, and have held these meanings since their very conception.

In order to save time and pixel-ink, I have decided to focus on the errors in a single sentence of your post.
IamJoseph writes:
...it fails till it succeeds1, and when a crevice of elevation is found, it is said to evolve into a higher2, more hardy life - this is termed as a mutation3 - while it helps a life form to progress to a new, higher level2, it also destroys4 the original host5 form.
(superscripts are mine, and correspond to comments made below)
1. If it fails, it fails. In evolution, failure = death. You don't get a second chance for evolutionary success if you're dead.
2. "Higher" beings only exist in religions. I know of worms that have been evolving longer than you have, and who have accrued more adaptations to their environment than you have, and have been infinitely more successful at reproducing than you have, so I see no reason why you are evolutionarily "higher" than that worm.
3. A mutation is a random change event in DNA. What you have described here could be thought of as an adaptation, or a synapomorphy, or simply, a novel trait. These are very different from what scientists call "mutations."
4. An offshoot from a single population can eventually become a distinct species without "destroying" the original species.
5. "Host" is a nice science-fiction term, but, in real science, it refers to mutualistic and parasitic relationships, not to evolutionary relationships.
---
Five misconceptions in one sentence (syntactically, it's actually just a clause, but let's not mince words), one of which was used twice. I think it should suffice to say that Subbie has been vindicated. Obviously.

All that I said was correct - w/o the jargon.
Which of the five were just jargon issues?

1. How is this a jargon issue? Failure in evolution means you die or you don't reproduce. Either way, your genes are completely gone, and will never be around again. In evolution, you succeed until you fail: you keep adapting to the environment, or else you die. As soon as you can no longer keep up with the environmental changes, you die. You should have said the exact opposite of what you did say, so I guess you could construe this as a “jargon” issue.
2. Evolution does not proceed toward a “higher” goal of any flippin’ kind: it goes “up” and “down,” depending on what is better suited to the environment. Loss of a trait (like legs) could not possibly be construed as “higher” or “more complex” in any conceivable way, but it makes snakes, caecilians, glass lizards, legless lizards, dolphins, seals, etc. more suited to their environment. If jargon issues Include saying things that are wrong, you are right that you have a jargon issue here.
3. You're right about this one: it's a jargon issue. You got yours from X-Men, where "mutation"="cool new trait/ability." In evolution, "mutation"="random change in a DNA sequence." But, your statement was “this is termed a mutation,” which shows that you really haven’t read scientific materials at all, so it’s more than just a jargon issue.
4. You say the new type automatically replaces the old type. Read here for thorough refutation (and unbridled mockery) of this idea. If ignorance is a “jargon” issue, then you’re right about this one being a jargon issue, too.
5. So, this one is also a jargon issue. But, you should really learn the jargon, anyway, because that’s how people tend to communicate with one another.
Some other "jargon" issues:
From Message #73:
IamJoseph writes:
The micro process has been traced to what is called a retro-virus, which, before perishing away, lodged an implant in a dna's gene, and this was passed on, even as the retro did not survive.
Retro-viruses can indeed cause changes in genome structure. However, so can UV rays, free radicals, random errors in the molecules that transcribe DNA, and a whole boatload of other mechanisms. So, if recognizing only one of several known mechanisms is a jargon issue, you’ve got another jargon issue here, alright.
IamJoseph writes:
While Darwin himself never said all life forms emerge from one molecule, or that there is cross-sepciation, this is the inferred premise, which has been expanded and accepted by the faculty called ToE.
Nobody really gives a wet slap what Darwin said anymore: he is not our prophet, and isn't even considered a real authority on evolution anymore. I know more about evolution with my B.S. degree in biology than Darwin ever did. When we have a question about how things happen, we do an experiment, or we talk to a modern specialist, we do not consult The Origin of Species. So, when you say "look what Darwin said," expect scientists to instantly consider you a moron who doesn't know how science (or evolution) works.
IamJoseph writes:
The highest species is definitely mentioned by a religious document, the same one which introduced evolution, and which placed humans a seperate category, and the final life from; this is vindicated w/o any confusion, and no need to wait millions of years or check it out in a lab. That's real science.
This is called quote-mining. It works well with the Bible (where it's called "Bible-bashing"), because every word of the Bible is supposed to be sacred and absolutely true. However, in scientific papers, it doesn't work: in order to make the paper cohesive, scientists have to write a few sentences that are not "sacred" (meaning, they're not part of the science)”so you don't get to just pull words out of stuff written by scientists and use it as scientific proof of anything, unless the words are the results of the experiment the paper is reporting on {AbE: and those words are still accepted in science today}.
For example, just because Darwin alludes to a Creator and that stuff in The Origin of Species, doesn't mean he has scientifically shown that a Creator exists. If you have read the book, and were paying attention, you would note that his mentioning of a Creator does not follow directly from the work that he did. That makes it part of his opinion, not part of his science.
So, if quote-mining (or Origin-bashing, if you want) is a jargon issue, you've got another jargon issue to fix.
If these all count as "jargon" issues, than the word "jargon" is as expansive and meaningless as the word "center."

Re: Jargon, the need to be straight with terms
Yrreg, look: we only get about 300 posts in a thread, as per board regulations, and we could easily use up all 300 posts trying to agree on just two or three terms that are involved in the debate. In fact, if you go to the "Is it Science?" forum, you'll find about half (exaggeration, obviously) of the threads exhausted on back-and-forth assertions that "faith" does or does not entail "blind" or "evidenceless" belief. If you read over all the threads on this website about "faith," "fact," "theory," etc., you would come to a very easy understanding as to why your idea of defining extra terms is getting a very hostile welcome in this thread.
Science has a set of terms that it uses regularly, and if you (generic "you") want to discuss whether or not the science of some topic is valid/factual/proven/etc., you have to use science terms to do it {AbE: and Coyote has provided you a location to find these terms}. If we're discussing religion, we'll use religious terms; if we're discussing comparative literature, we'll use comparative literature terms; if we're discussing ballet, we'll use ballet terms. If you want to discuss terminological issues, do so in your own thread about terminology.
This thread was started because anti-evos continuously come onto the website making off-the-wall claims about evolution that leave us science types baffled. Note that every creationist responding to subbie's challenge so far has included abiogenesis and Big Bang cosmology as parts of evolution. And, on other threads, they routinely provide "evidence" against these concepts, thinking that, if they can disprove, e.g., the Big Bang, they have successfully disproven evolutionary theory. Then, we have to go through this entire explanation of "what is evolution?" yet again. Now, though, we can just direct people to this thread (or others like it) when they bring up stuff like that again, instead of wasting another 300 posts explaining what evolution is and never getting to the topic that the OP wanted to discuss.
So, subbie put this thread out so we can see what the misunderstandings are, and try to correct them. Now, you want us to use up this thread defining other terms like "fact" and "change," when this forum was not started to discuss whether or not evolution is a fact or to engage in an infinite regression of definitions. Who cares if Bluejay calls it a theory while Coyote or Rahvin calls it a fact? How would that change what the fact/theory says? And, if you noticed, what it says is the topic of this thread.
If you really think "what is a fact?", or "should evolution be considered a fact or a theory?" should be discussed, and you don't see the matter having already been discussed thoroughly enough on other threads, propose a topic for it in the "Proposed New Topics" forum.
