You cannot show that the horseshoe crabs did mutate. You cannot show that they did evolve. You cannot show that their genes did change. You cannot show that their environments did change. You cannot show that their environments did not stay the same. What exactly can you show us, BVZ? I find it interesting that evolutionists always manuever when evidence is non-existent! Yeah, it 's as if I say, "There is no evidence that these organisms evolved" and the evolutionist shouts back, "You cannot show us there is no evidence!" Actually, no. What I am pointing out is you have no evidence supporting your case. And you don't. But maybe I am wrong. If you DO have evidence supporting your case, feel free to present it.

I think the fact is pretty well demonstrated.

No, you want ID taught against evolution. However, science is not a contest.

If these organisms (sponges, jellyfish, ostracods, ants, beetles, flowering plants, crayfish, horseshoe crabs) haven't evolved in hundreds of millions of years, then that means that evolution isn't necessarily a regular and expected condition of life, and it isn't necessary for long term survival. An organism can mutate all it wants, but if such a mutation evokes no change in the organism, it's not evolving.

Mutation is irrelevant in this case as presumed mutations evoked no change in the organisms in question. The organisms simply didn't evolve, because evolution requires an expressed mutation.

The fact that they have remained unchanged since their "arrival" on this earth is not addressed or is waved over.

Stasis is not the exception, it seems to happen just as often as evolution. So genetic drift is a crock.

Yes. It is very interesting. But if you look at Juhds argument, he is saying that they did not EVOLVE. Yet he cannot show this, since there is no genetic material to inspect. I combined the last two because they're the same argument. I don't think that we need the necessarily know the genotype because we can reasonably conclude that since the phenotypes have stayed the same, the genotypes stayed the same. We have whole fish that are fossilized, it's no secret that fish are not models for evolution because of the stasis of the several species. Not surprisingly, it's the stuff that does fossilize that seems to be remaining static. Sponge spicules have remain unchanged, so we're forced to assume that it was only the choanocytes and amoebocytes within them that evolved. The shell of the chambered nautilus remained unchanged (and highly complex in its own right) so we are forced to assume that the great leap from nautilus to cuttle fish, to squid just happened without leaving any evidence. And yet we still have the nautilus here with us today, and the parts that did remain from its ancestors are still identical to what we have today. quote:

The molecular workings of these creatures might become more efficient and streamlined, but the phenotype will remain the same, since there is no reason for it to change. Right, and I alluded to this above. The evidence points to stasis, but their is room within the evidence for a lack of stasis. What we see is a phenotype that remains unchanged relative to what is expected by genetic drift. 500 million years of evolution did not change the shell of the nautilus unless we assume that it became the cuttle-bone of the cuttle fish and the pen of the squid. Even more evolution didn't change the spicules and spongin of the sponge. What we observe is stasis; we must assume that there was genetic drift. quote:
Questions: 1) Why do you say genetic drift is a crock, if you don't have access to the genetic material? 2) What makes you think that these creatures did not mutate? 3) What makes you think that a static phenotype is a problem for evolution? Answers: 1)genotypic variation is manifested in phenotypic changes 2)Why must we assume that they did? 3)It's not. Its defenders will doubtless rise to the occasion of waving their hands in the face of the evidence and continue teaching it unquestioningly to their students as the #1 unifying theory in all of science to which all other sciences must bow the knee in penitent obedience. But to answer your question. It's a problem for evolution because it's not just "a static phenotype" it's the prevalence of static organisms. Throughout all the major phyla we have species that have remained (from the material that we observe) completely or at least greatly unchanged throughout the supposed millions or hundreds of millions of years that they are supposed to have existed. The examples that Jhud has given is merely a sample.

No, I have been saying, and no one has refuted, that there is no evidence of evolution. If the fossil record of morpohological differences can be held up as evidence of evolution, then certainly the lack of morphological change is evidence for lack of evolution. Indeed, unexpressed traits have little relevance to evolution or this discussion.

Horse is a good example of evolutionary change from the small Eohippus to what it is now.....sure there are organisms and animals that have not changed in millions of years the crocdile and shark are two of them only their size has changed not as big as their ancestors. All this is really moot points evolutionary changes have occurred to what extent who knows. Are they in line with Biblical teachings? Who knows?

I am not sure it is moot when there are hundreds of millions of years with no discernible change. This would contradict the notion that variation is commonplace and consistent.

There is change. Earth is not the same as it was climatic changes and stuff. Not sure what you mean by by discernible change. Discernible change in what? Man, animals, weather? You can present all the evidence you want as far as this evolution junk goes people are blind when it comes to things not written in scripture that simple. Maybe G-d had a reason who knows. But the fact remains that time changes everything. Dinosaurs existed fossil proof now some extremist will disagree because its not in the Bible but that said its hard too see the forest for the trees. My opinion here is split all I can say at this point. There are some good points but its hard to dispute hard cold evidence......

I don't know enough about the subject to comment really; I can see that scientists consider stasis as a 'challenge' for evolution, but hardly as a stake through the heart. As for me, I don't think the existence of dud firecrackers is evidence for lack of combustion. Sure, that firecracker didn't combust, but that doesn't somehow disprove the general 'theory of combustion'. I don't see why there should be any requirement that species must radically change in ways that leave a record in their fossils. If a species happens to sit on top a nice pointy hill in the fitness landscape, there is no pressure to evolve away from it (and a strong disincentive to do so). Does the modern theory of evolution predict that such pointy parts of the fitness landscape can't exist? I don't see why it should. Although the basic rate of mutation is roughly constant across species, that doesn't necessarily translate into a constant rate of morphological change. Out of the millions of evolving species... some, it would seem, must evolve 'less' than others.

In the cases of stasis there is no evidence of evolution. Of course morphological differences exist (or every organism would be the same) and if those differences can be held up as evidence of evolution, then the lack of differences between organisms that existed in the past, and those that exist now should be considered evidence that evolution didn't occur in those cases. quote:

I appreciate your willingness to admit it's a challenge to evolution.

The shell of the chambered nautilus remained unchanged (and highly complex in its own right) so we are forced to assume that the great leap from nautilus to cuttle fish, to squid just happened without leaving any evidence. When you are forced to make assumptions, it kind of makes sense to use the most powerful scientific theory available. quote:
And yet we still have the nautilus here with us today, and the parts that did remain from its ancestors are still identical to what we have today. Agreed. However, before this can become a problem for evolution, it first must be a problem for evolution. Since it's not, it's not. quote:
quote:
Before this argument can continue, you have to show that these creatures actually remained static. Remember, creatures are selected for or against based on their phenotype. As long as the genes results in a phenotype that is well adapted, the phenotype will not change. But the biological processes that CREATES the shape might change. The molecular workings of these creatures might become more efficient and streamlined, but the phenotype will remain the same, since there is no reason for it to change. Right, and I alluded to this above. The evidence points to stasis, but their is room within the evidence for a lack of stasis. What we see is a phenotype that remains unchanged relative to what is expected by genetic drift. Why do you think genetic drift predicts the phenotype should change? If a local optimum has been reached, genetic drift will not move it out of that region. quote:
500 million years of evolution did not change the shell of the nautilus unless we assume that it became the cuttle-bone of the cuttle fish and the pen of the squid. Even more evolution didn't change the spicules and spongin of the sponge. What we observe is stasis; we must assume that there was genetic drift. Evolution predicts that there was genetic drift. Evolution also predicts that any genetic drift that makes the creature LESS FIT will be eliminated. Which is why the phenotype is not expected to change, when the phenotype is extremely well adapted. Remember, genetic drift ONLY applies on neutral changes. quote:
quote:
Questions: 1) Why do you say genetic drift is a crock, if you don't have access to the genetic material? 2) What makes you think that these creatures did not mutate? 3) What makes you think that a static phenotype is a problem for evolution? Answers: 1)genotypic variation is manifested in phenotypic changes Agreed. But if the only parts that are fossilised are critical for survival, genetic drift does not have to have an effect on the phenotype. quote:
2)Why must we assume that they did? A complete lack of mutations requires a mechanism that stops mutations to occur. No such mechanism exists. A complete lack of mutations poses significant problems for the theory of evolution, since evolution requires imperfect replicators to function. Replicators without mutations would be perfect replicators. quote:
3)It's not. Its defenders will doubtless rise to the occasion of waving their hands in the face of the evidence and continue teaching it unquestioningly to their students as the #1 unifying theory in all of science to which all other sciences must bow the knee in penitent obedience. Could you give me an example of a branch of science outside biology that has to 'bow its knee' to evolution? quote:
But to answer your question. It's a problem for evolution because it's not just "a static phenotype" it's the prevalence of static organisms. Throughout all the major phyla we have species that have remained (from the material that we observe) completely or at least greatly unchanged throughout the supposed millions or hundreds of millions of years that they are supposed to have existed. The examples that Jhud has given is merely a sample. The existence of a thing is not enough. For that thing to become a problem for a scientific theory, it actually has to become a problem first. If you could explain to me how it is a problem, then we can continue this discussion.

ORIGINAL: Jhud quote:
Yes. It is very interesting. But if you look at Juhds argument, he is saying that they did not EVOLVE. Yet he cannot show this, since there is no genetic material to inspect. No, I have been saying, and no one has refuted, that there is no evidence of evolution. If the fossil record of morpohological differences can be held up as evidence of evolution, then certainly the lack of morphological change is evidence for lack of evolution. You are wrong. When phenotypes in fossils change over time, we know that the genetic material has changed, since the phenotype is generated from the genotype. When the phenotypes in fossils DO NOT change, like we see in the examples you have provided, we can't conclude anything, so we don't. We can use the already strong scientific theories we DO have to make predictions however. Such as: 1) Mutations must have occurred in the static creatures. 2) The parts of their phenotype (that can fossilize) must have been very well adapted to their environment. 3) Their environment remained static for a very long time. These predictions are falsifiable. Now, if you want to damage evolution, you can try to show these predictions to be false. But the mere existence of stasis is not a problem for evolution.
