Re: The what?
Basically, he wants to be able to say that the various laws of physical nature only work back to some point in the past and beyond that, absolutely nothing can be said. Depending on how far he wants to take it, it is nothing but a thinly veiled variant of the, "Were you there?" argument: That because humans were not physically present to directly observe the biological processes of the past, then we cannot say anything about what happened, as if we had no physical evidence of what did.
Well, to be fair, science as a general rule of thumb must base its fledgling theories with observation, testing of hypotheses, and repeating the processes. Neither of those fit the criteria for the theory of evolution.
Darwinian macroevolution has never been directly observed, to which you might reply, it takes years and years to accumulate enough minor gradations. Its like trying to watch fingernails grow!
But the thing is, fossils are snapshots in history. And in the same way you might not be able to see one's fingernails or hair grow, directly, you can still see clear evidence of it from those snapshots.
The fossil record is inept in answering these questions because we do not see any clear examples of transitional forms. Indeed, this has long been the problem for evolutionists. But the argument is brought up so much now or days against evolution that it is not as widely admitted as it was in the past.
The second tier is with the fact that evolution cannot be duplicated in a lab. For instance, the Drosphila Melanogaster, which is your average fruit fly. Numerous scientists have bombarded these fruit flies with X-ray radiation, among other techniques, in order to mutate them. Well, it worked remarkably well. They were able to produce offspring with eyes missing and wings growing out of their heads. But I suppose the point is, no bionic fruit fly was ever the bi-product of these experiments. (No dragonflies, houseflies, horseflies, butterflies, were ever bioengineered-- just fruit flies and lots of them).
Of those that actually survived essentially produced monstrosities with horrible deformities that certainly would have eliminated them in the wild. Natural selection works against the typical evolutionary model because it does not further the advancement of mutations, but rather, tends to weed out any aberrations.
The Drosophila has been no exception to the rule. Even more damning, the fruit fly is molecularly very simple in relation to that of a human. What is worse, their lifespan is not even a thousandth to that of the average human lifespan. What does this mean? Essentially, it means that the fruit fly has the physical ability to evolve more readily than that of a human being. The fruit fly is relatively simple with a genome, composed of four pairs of chromosomes, of about 13,000 genes.
Aside from this, they breed at a much quicker rate. So, then, surely in 80 to 90 years of experimentation, their generations would be into the hundreds of thousands. Compare that figure to humans. In 80 or 90 years, how many generations have come out of your immediate family? Most likely, about three generations, and maybe four in that amount of time.
If ever there were a prime candidate for proving macroevolution, the Drosophilia would be it, and yet, nothing even comparable has ever been established.
Lastly, they cannot repeat the results of the experiment because they cannot simulate it in the lab to begin with.
Therefore, I scarcely see how dissenting objections to evolution should be viewed with such scathing anger. (Not you, but in general) For how ever misguided you'd like to say creationists are, they have some very reasonable objections to the theory.
Having said that, they have to respond to some very reasonable postulates presented by evolutionists until a solid consensus can't be found in some appreciable way.

Re: The what?
Wow. One giant post of inanity.
No, please don't hold back for my sake... Tell me how you really feel.
First, your objection to the fossil record. There are clear transitionals in the fossils. Furthermore, I believe they are called foraminifera, but they have essentially the entire evolutionary history (in fossils). Unfortunately, I can't find a link to the evolutionary history I'm thinking of. Which means I might have the wrong organism in mind. Someone on this board knows what I'm talking about though, I suspect.
Shouldn't evidence for macroevolution be so completely abundant so as to be self-evident? Should it really be necessary that you have to find some obscure creature that might qualify, if the theory is as strong as it claims?
Second, the D. melanogaster experiments were not designed to test evolution.
What was the function then? If my memory serves correct, they were looking at specifically homeobox sequences to see if intentional tweaking could speed up speciation.
Tell me, did those experiments include natural selection in the design? No. They were designed, if I recall correctly, to test specific effects of mutations in certain genes.
The mutants were so badly mutated that there was no hope for survival as a wild phenotype. I even said that natural selection weeds out aberrations such as these. We're talking about flies with antennae growing out of their eyes and other bizarre mutations. Obviously that's hardly a beneficial mutation.
I think part of the problem was that homeobox genes only turn on or off other genes that are already extant. I think at the time they were hoping for something far more grand.
In order to design an experiment to test evolution, you not only need to cause mutation (such as with radiation), but have a selection factor. The drosophila melanogaster experiments were not designed to test evolution!
Even supposing that is the case, I'm curious to know if any acid tests have been conducted, and if so, what did it consist of?
Oh, by the way, the human genome consists of 20-25,000 genes. The fruit fly? Around 13,000, like you say. So we have maybe twice the number of genes, but ten times the number of chromosomes. How many did you think we humans have?
Whether it was half or 4 times as many is beside the point. The point I'm making is that they are simpler than that of humans, procreate much faster, are more prone to mutation, etc. The point is that they are a much coveted test experiment for evolution, but it yielded unfavorable results unworthy of defending the theory.

Re: The what?
It was all over the news two years ago. The best thing about it is that it wasn't found by accident - paleontologists searched geological structures of a certain type and age, thus demonstrating the predictive capacity of the physical evidence used to support the TOE.
Yes, I was aware of the argument when it was discovered. Naturally, I remain unconvinced. And this is due in part that it is incomplete. We know nothing of the hindquarters, yet we're told that its essentially a missing link.
I wonder that if mudskippers were extinct right now, if evolutionists would make the argument that they were really creatures in transition from water to terrestrial, or vice versa.

Re: The what?
About your fruit fly speciation claims, experiments of all different sorts have been performed on Drosophila melanogaster
Yes, I am aware of that the fruit fly has been used in a multifaceted way. I'm simply mentioning the Drosophila because it is used as evidence of speciation. I'm really not sure where the ambiguity is in that.
Though not impossible, bombarding fruit flies with X-rays is unlikely to produce such specific mutations.
But it is what they did. If your objection is that the expressed intent was not specifically to, in essence, "prove" evolution, then I can't really comment on that. All I know is that the fruit fly has been used as an evidentiary claim for macroevolution. I am simply dispelling the notion that it proved anything in favor of macroevolution. In my mind, it did prove quite nicely that the abundance of beneficial mutations are little more than wishful thinking.
we've observed speciation both in the lab and in the wild multiple times. Your observation about the slowness of speciation in longer-lived species is accurate, but this comment about the fossil record is also clearly wrong
Percy, its just an illustration so the reader understands what I mean. I don't see how that could be "clearly wrong."
I would also like to see the alleged instances of observed speciation. I'm guessing it is going to show various forms of microevolutionary specimens that no one objects to.
There are many examples of transitional forms in the fossil record, if for no other reason than that all species are transitional, except those that go extinct.
Its a stretch that defies imagination that the horse and whale series produced anything of value. Its based purely on conjecture.
The fossil record is full of finely gradated series of species change. What is less common in the fossil record is transitions at the higher levels of classification such as class and order.
Then where does a theory like punctuated equilibrium come in to play that contravenes the supposed finely gradated series? There are no finely gradated series. There are organisms that appear fully-formed in strata just as they are walking around today.
You were probably just responding to something someone else said, but I thought it important to respond to your errors, but I think this may be drifting off-topic.
I don't see how this off-topic, being that the premise of the OP is quite broad.
You're lack of familiarity with the fossil record and with speciation experiments isn't an issue in this thread, and probably disqualifies you from the discussion anyway.
Is that a more gentle of way of saying, shut up, nem... you don't know what you're talking about.?

Re: The what?
Convincing you is, naturally, an impossible task. You know, I've read your posts for a while now and I'm actually shocked that you remain so ignorant (but I guess I shouldn't be). Is it the Jesus thing? Dude, get religion off your brain for a minute and actually learn something. Incredible.
And I've read your posts as well. They lack any substance. They are reminiscent of Rick JB's posts which are pithy, at best, and ad hominem at worst.
You'd attract more flies with honey than with vinegar. In the future, perhaps you could make an attempt to be affable instead of instantly trying to blast me out of the water.
