Re: Semantics
I'm trying to keep beliefs out of it, sorry Pressie. I'm interested in the Science of it right now and classification and how and why classify the way we do and how I can possibly come up with a definition of "kinds" that can be worked into a scientific hypothesis for Creation.
Well, the creationist idea of a kind is a clade which is not contained inside another clade.
Put another way, a kind is a group of species such that (a) a creationist will admit that they're related (b) the creationist won't admit that anything outside that group is related to anything inside that group.
This varies, of course, from creationist to creationist. Determining the limits of kinds is difficult, for two reasons.
The first is that while creationists are otherwise happy to lump species together, and will talk with a fine freedom of "the dinosaur kind" or "the beetle kind", they nonetheless want humans to be a different kind from chimps. Now, how do you come up with genetic or morphological criteria that will split humans from chimps but allow you to lump together dinosaurs, or beetles --- or even Felidae?
The second problem is this. All the scientific methods that unite a clade that they want to be a kind (e.g. Felidae) would also unite clades they don't want to be a kind (e.g. Carnivora). There is no non-arbitrary place to stop; the creationist who has happily been using molecular phylogeny up to that point just has to exclaim: "Now that's going too far, because I don't believe that!" (And again, what a creationist finds acceptable will vary from case to case.) There is no non-arbitrary point at which one can say "Now I'm going to stop believing the results of the methods which have suited me fine up until now."
---
Addendum: actually, there is one non-arbitrary place to stop, which is to identify kinds with the Biological Species Concept. The trouble is that that splits kinds up rather fine. The idea of "kinds" was invented to explain how Noah fitted everything onto the Ark, and if you go with the B.S.C. then it's really not that much use.

Re: what is novel?
So do you mean that the dog got/evolved its "webbed feet" AFTER getting into a very strong ocean current or BEFORE?
If yes, or after, then, how many times did the dog go to the ocean so that it acquired its own webbed feet?
Do you have an experiment or record for that?
You have no idea what the theory of evolution is.
You are therefore incompetent to discuss it.

I know I already said that in post #37, but it seemed worth saying again. 'Cos of being so profoundly true.

Re: To PRESSIE
Those population don't evolve. They are just adapting, if you are talking about change in whatsoever "changes" you may call, those change is not evolution. It is only adaptation.
You really are all at sea about the most basic concepts in evolution, aren't you?
Now, you told me that I don't know evolution or ToE? If I don't know it, I cannot argue with you.
Then this would be an excellent time to stop trying.

Re: To PRESSIE
You don't know what I've discovered. Then, why do you say that?
Because I do know, from reading your messages, that you don't know much about evolution, which is what I said. I know this 'cos you keep misstating the theory, so unless this arises from willful dishonesty, it must necessarily arise from ignorance. You need to start again from the beginning, and find out the role of mutation and of natural selection in the theory, otherwise you will continue to make the crass blunders which so far have been the most egregious feature of your posts.
Plenty of people have explained it to you on this thread alone. Also there are textbooks available which would assist you. If after consulting these resources you still have difficulty in understanding evolution, I shall see what I can do to help.

Intelligence
Do you really not see how intelligence is a trait that might have a selective advantage?
No, possibly you don't.
In that case, feel free to be even more stupid than you are now, especially when crossing the road, and see how you get on.
Alternatively, you could try to be more intelligent. But you might have to give up being a creationist.
We evolutionists think that intelligence is a desirable trait, but then we're biased 'cos it's one that we possess.

Re: how populations evolve - when is it "novel"?
Yeah, I knew that there are changes BUT those changes cannot produce new species! Is that hard to understand? I knew that population is composed of individuals. I knew that population changes but they don't change to become new species.
Yes, gene mutates. But let me get straight: If gen1 has the following traits, t1, t2, t3, t4, t5, t6, t7, t8, t9, t10..., then, the gen2 may get the same traits in a mixed order: t10, t2, t6, t4, t5, t1, t7, t8, t9, t3,...and the third generation, gen3, may get another mixed traits...but the gene cannot mutate traits that are NOT present in gen1!
But why do we see changes? We see changes because genes are being mixed up. Say, t1 is a genius trait, t1 can be present in gen1, but it will never be present in gen2, but it doesn't mean that gen2 has no t1 trait! It is very simple!
This is so far from actual genetics that it's not even clear what it is you're trying to be wrong about. It's as though someone was to pretend to be knowledgeable about sports by saying: "The second baseman was caught leg before wicket, so the goalie was awarded a slam-dunk" ... it's not merely that this is a description of something that never happened, it's not even a description of something.
Perhaps you should begin by learning the meaning of the word "trait". A trait is a possible variant of a character: e.g. if the character is eye color, blue eyes would be a trait; if the character is whether or not one has earlobes, then having earlobes is a trait.
Now, obviously it make no sense to talk of the order of traits, there's no difference between having blue eyes and earlobes and having earlobes and blue eyes. The idea of "the same traits in a mixed order" doesn't mean anything.
You see, ToE is messing up science. You messes science!
Either that, or geneticists know about genetics and you don't.
I think you should be reading and using a critical thinking.
I have followed your advice and concluded that you are spouting ignorant claptrap.

Re: how populations evolve - when is it "novel"?
Let us go back to our example:
If generation1 (gen1) had the following traits as a whole (take note: as a whole)
t1, t2, t3, t4, t5...., t100, (from t1 until t100)
then gen1 will reproduce the same traits to gen2, but since there is no "perfect clone", then, the traits will be mixed up in arrangement, like this
t3, t50, 67, 80, ....t1...(the same complete genes/traits with gen1).
Again, you're not exactly painting a picture. What, in the real world, do you want to correspond to the "arrangement" of the traits?
Instead of a hundred traits, let's consider two --- the two I've mentioned. Let t1 = having blue eyes, and t2 = having earlobes.
What is the difference between the "arrangement" t1, t2 and the "arrangement" t2, t1?
The problem is: when gen1 reproduces gen2, will t200 or t500, new traits, will be formed? No! Since how could genes mutates if that t200 or t500 is not present in gen1?
Now you need to learn the meaning of the word "mutate".
You see, ToE is messing up science and making fantasy.
Am I rght?
No. You are pathetically, ludicrously wrong.

Re: how populations evolve - when is it "novel"?
OK, let us use your scenario.
Yes, that is a change! From this combination: t1, t2 to this combination, t2, t1...that is exactly a change.
Please answer the question. What is the real-world difference corresponding to the different "arrangement"? If one generation has blue eyes and earlobes, and the next generation has earlobes and blue eyes, then what "change" has occurred?
So, where is evolution and where is mutation? Do you imply that t3 will be formed? That is a fantasy! OK, I'll play. BUT you need to be sure that you know the meaning of "inheritable traits" because this will be the biggest blow to ToE.
How can you show that t3 will be formed by mutation or evolution?
We can watch new traits arising, but that of course involves looking at the real world rather than the muddled mess of verbiage in your head, and so you may have overlooked it.

Re: how populations evolve - when is it "novel"?
The change that occurred is the arrangement of its location.
How does a trait have a "location"?
That what we see in the real world ...
What do we see? How can we look at two populations and say: now this population has blue eyes and earlobes, but that population has earlobes and blue eyes?
In what way are the "arrangement" and the "location" of these two traits visible?
So, you are implying that t3 is arising even though it is not present in gen1? Am I right? So, meaning, the "inheritable traits, say t1, t2 of gen1 to gen2 is wrong?
How can you explain that when ToE claimed that inheritable traits is part of evolution?
Perhaps this meant something in your first language, but it seems to have lost something in translation.
Maybe you can enlighten me ...
I'm not sure I can. Maybe the best I can do for you is advise you that if you keep quiet people won't notice how ignorant you are.
... up since until now ToE and you is messing science.
Well, not according to scientists, who know about science, it isn't. If you, a non-scientist who is profoundly ignorant of science, have a different opinion, then I would suggest to you that maybe it is they who are right and you who is wrong.

Re: how populations evolve - when is it "novel"?
Actually it is a neutral mutation ...
Not even that. It's simply meaningless, a distinction without a difference.
Remember, we're talking here about phenotype, not genotype.

Re: how populations evolve - when is it "novel"?
Yet it is a fairly common mutation to flip sections of DNA around without altering their expression in the phenotype.
Yes, but that's not what we're talking about. If the gene for eye color swapped places on a chromosome with the gene for earlobes, that would be a neutral mutation. But what can it even mean for two traits to swap places?
It may be that intellen is trying to be wrong about the genotype rather than the phenotype, in which case now would be a good time for him to say so.

Information
Not at all,Here is the Wiki demonstrating the relationship between entropy and information.
[...]
Can you walk me threw how exactly you can draw a conclusion about the ease of creating information from that citation?
Well, if your choice is Shannon entropy, then creating information is easy. Any insertion would do it, since the insertion increases the number of bits in the genome, and since the content of these bits is not completely predictable from their context.
So, for example, consider a "toy genome" (real genomes are of course longer) of the form GTACT_ACTCTA, where the _ represents a base that has just been added by insertion, the identity of which I am not going to tell you.
Can you deduce with complete certainty what base is represented by the _, based only on the knowledge that it is preceded by GTACT and followed by ACTCTA?
Of course not. Therefore, it makes a non-zero contribution to the total Shannon entropy of the genome.
See, it is easy.
Are changes in an organism only because of adaptation (microevolution)?
Sentences like this usually betoken a fundamental misunderstanding of either the theory of evolution, the meaning of the word "adaptation", or both --- but you do not make the error explicit, you just take is as read. Perhaps you could explain why in the name of all that is asinine you wrote "adaptation (microevolution)", and then when we've cleared that up we could go on to discuss something else, such as E. coli and nylonase. But this hardly seems worthwhile if you're still confused about really basic concepts.

Re: Logic
Evolution is both fact and theory.Theory because it is always changing from new information.*also a hurt to evolution
And it is fact because methods and patterns observed are proven.
Though the question is, has the evolutionary theory really completely explained evolution?No it hasn't.Have they discovered any process of genetics which can evolve anything new?No
Fossils speak of sudden appearances of the kinds of fast paced change not exzactly hand in hand with evolution.Nature is rich with biological designs which out right deny evolution.
Amounst animals that do are:the bombardier beetle,the giraffe, the gecko, and the humming bird to name a few.
While we able to apprehend a Creator we can not comprehend Him and that is the problem.
If specific animals do not fit the theory of evolution the house of cards implodes.
Ultimately with animals and fossils recorded not fully supporting evolution the design of the world rests upon a Creator.
Thank you for your Gish Gallop. If there is any specific point in it that you feel capable of defending, please start a thread on it, where you will be shown how wrong you are. Otherwise please be informed that you are reciting ignorant trash invented by liars and fools to deceive the gullible.

Re: Information
You are really going to have to go into the math here.
Well where do I start? You referred us to an article on Shannon entropy. I have a Ph.D. in mathematics, and I (perhaps foolishly) assumed that when you started talking about Shannon entropy, you knew what you were talking about.
Apparently you don't. So, tell us --- at what point do you start finding information theory incomprehensible? Maybe I could help you over that hump. But until I have, maybe you should stop talking about information theory.
