Because you don't want to admit that finches mating right in front of their noses are the same species and therefore Darwin was wrong.....

For example the western populations of the Yellow-rumped Warbler (which have yellow throats) were previously considered a species, Audubon's Warbler, distinct from the eastern Myrtle Warblers (which have white throats), largely because of differences in appearance. Then it was discovered that the breeding ranges of Audubon's and Myrtle Warblers overlap broadly in a band from southeastern Alaska through central British Columbia to southern Alberta, and that the two "species" hybridize freely within this area. The forms intergrade, and taxonomists now consider them to be subspecies of a single species, the Yellow-rumped Warbler. Subspecies are simply populations or sets of populations within a species that are sufficiently distinct that taxonomists have found it convenient to formally name them, but not distinct enough to prevent hybridization where two populations come into contact.


It has to do with ignoring they are the same species.....

Seems to go against their own classifications.....

Good grief man, I assume that you actually read the article that you extensively copied? You do realise that it succinctly addresses all these foolish objections you constantly spam?

I can see why you didn’t link to it though.

Species and Speciation

“Judgments about whether two populations should be considered different species or just different subspecies may be very difficult to make. For instance, in some areas where populations of Red-breasted and Yellow-bellied Sapsuckers meet, they hybridize, whereas in other areas of overlap they do not. As a result, ornithologists do not agree upon whether to consider the two forms as separate species or as subspecies of the same species. In situations where differentiated, but clearly closely related forms replace one another geographically, taxonomists often consider them to be separate species within a superspecies.

These complications are a natural result of applying a hierarchical taxonomic system, developed a century before Darwin, to the results of a continuous evolutionary process.“

Succinctly Addresses is kind of a stretch of words isn't it? You mean it asked a lot of questions to which it already answered....

Let's look at your claimed reasoning....

"For instance, in some areas where populations of Red-breasted and Yellow-bellied Sapsuckers meet, they hybridize, whereas in other areas of overlap they do not. As a result, ornithologists do not agree upon whether to consider the two forms as separate species or as subspecies of the same species."

And why not?

You see them mating right in front of their noses...... "The forms intergrade, and taxonomists now consider them to be subspecies of a single species"

Are not the ones "where populations of Red-breasted and Yellow-bellied Sapsuckers meet, they hybridize" the same situation as with the warblers? There is no shaded area here except in your own mind because you need to prove speciation where it does not exist. Your thoughts and judgements are colored by it so much you can't even see their own contradictions.

It is irrelevant if in some areas they do not mate, in some areas they do, and therefore they hybridize and are merely subspecies......

But you can't handle logical thinking because being held to logic would destroy your claims of speciation.....

Isn't that good enough?

You want to know what a kind is: it is a genus of animal that was created to replenish the earth.

Except the idea of "genus" is one created by humans. How that can be the determining factor in something God made I have no idea.

No, you didn't.

Yes I did.

I showed you pictures of two animals and asked if they were the same "Kind" or not.

In post 148 you said you couldn't answer that without knowing what genus they were.

In post 150 I pointed out that you shouldn't need to know some arbitrary label given by Humans in order to understand the work of God.

Seriously, AV, this line of debate is pretty weak, even from you. According to your logic, back before Carl Linnaeus, people would have the following conversation:

Person 1: Are these two animals the same kind or not? I can't tell!

Person 2: Well, we can figure it out easily, what genus do they belong to?

Person 1: I don't know, Carl hasn't got around to inventing his system of taxonomic classification yet.

Person 2: Well, we can't figure it out until he does! I wish he'd hurry up!

Humans who investigated God's kinds and gave them a classification that already had one.

In short, they stamped the word GENUS over the word KIND.

Now they want a definition of KIND, and don't realize they already have one.

And? The offspring of a Mastiff and a Husky is a Chinook. Doesn't make the Chinook a hybrid, now does it?????

And given that both male and female offspring from such a pairing would be fertile, it indicates that the two parent dogs are much more closely related than a lion and a tiger.

Your example falls apart.

Avoidance.....

What species is it then? They call those finches hybrids too, yet each is also called a distinct species......

Liger species.jpg


Then only the males would be a separate species??????

Why are you trying to talk about biology when you obviously have no idea how it works?

it is painful trying to watch you do and say anything to avoid answering the questions....

It's painful trying to talk to you about biology when you know so little about it that you are incapable of knowing how little you know about it.

Ahhh, so now you want to go from "and since they are larger than lions and tigers, giving birth is dangerous and often requires the mother to have a C-section."

to suddenly MAY...

You are so full of double-talk you should wash your mouth out....

Wow, you are totally incapable of actually comprehending English, aren't you?

First, I posted that source that said MAY the very first time I brought up the subject, so you can't say I have changed my views. I am reiterating the view given by the source I posted the very first time we discussed it.

Secondly, in that same post, I said "OFTEN" requires C sections.

And yet now you are trying to claim that I said that they ALWAYS required C sections and have since changed that claim. I have done no such thing. Don't lie to me about the things that I have said. NA dif that's the only way you can make your point, then your point is rubbish and should be kept silent.

And apparently you didn't read my source from the Liger foundation itself..... which states that when born Ligers are no bigger than Tigers. They simply grow faster after birth......

I'll accept that. In any case, it doesn't take away from my other points - the infertility of male ligers indicates that lions and tigers are evolving away from each other, and the fertility problems we see are exactly what we'd expect to see if evolution were true.

Now they want a definition of KIND, and don't realize they already have one.

So if the idea of "Genus" was simply putting a different label on something that was already there, you surely don't need the genus name, just go with what was there before the genus label was around, okay?

If you want to use the label, use the label.

If you want to categorize a lion and call it Panthera leo, then do so if it'll help you understand the animal world more.

But don't go around saying "Panthera" is not a "kind" because Panthera is a "genus," or you need to be corrected.

Reportable, Sir. Can you keep the topic on the OP?
No, sir, valid conclusions premised on your posts are not reportable. Spam-trolling with the same 'questions;' even when they have been answered over and over is, however.

I also note that you have ignored my comments ON TOPIC. You have a distinct tendency to do this when people illustrate the naivete and repetitive dishonesty of your "questions" and 'new' threads that are really the same as all of your other threads.

You ignore what people supply you with and explain to you. You regurgitate the same "questions" that you ask in nearly every thread, regardless of relevance, no matter how many times your erroneous implications and assertions are refuted.

You ignore questions asked of you, the answers of which would make your "questions" more meaningful (i.e., 'Why do you think there should be something between fossil X and fossil Y?', 'What do you mean by 'macro assemblage?', etc.).

You just need to make yourself feel special by trying to browbeat people that understand how little you understand, and it is failing,.

Horribly.

Note that Heissonear cannot answer simple questions based on his repetitive assertions.
Please explain what you mean by "in between".

What comes between a parent with a normal phenotype:

and their achondroplastic child:

https://boneclones.com/images/store-product/product-1361-title-title-grid-view-1418245473.jpg

I have asked you many times - each time you ignored the questions - why do you think there SHOULD be an 'in between' fossil?

1. Look and see if they are the same genus.

2. See if they can produce fertile offspring, which can produce fertile offspring.
Then the label "kind", and the nonense associated with it, is in direct conflict with the existance of ring species.

I see.

So God, in His infinite wisdom, can't put a boundary on the diameter of a ring species?

Or God, by choice, can't put a restriction on a species operating within its own kind?

(I can't believe I'm letting you drag me into the area of species, when I'm talking about kinds; but I won't let it go far though.)

Doesn't matter.

You gave a definition for what "kinds" are.
And according to your definition, things like "ring species" couldn't exist.

But they do exist.
So your definition MUST be incorrect.

You are welcome to invoke more "miracles" or "magic" to "handwave away" all the evidence that doesn't fit in your narrow fundamentalist biblical bubble view of the world though.

But such behaviour only makes it worse from my perspective.

When data shows that your ideas are wrong, it's your ideas that must change.

You already slagged the Bible's morals.

You already said the Douay and King James are the same.

The only way it can get worse from there is to become a scientist.

They are incredibly lacking, as shown by your repeatedly not understanding what introgression is....
The projection in thunderous...

You seem to think that introgression "creates" new alleles. Yet this is clearly not the case, even in the quotes you provide.

Introgression, as the word should imply, is the introduction of new alleles from one individual/population into another (gene flow). Here, let me school you again:

"Introgression (or “introgressive hybridization”) describes the incorporation (usually via hybridization and backcrossing) of alleles from one entity (species) into the gene pool of a second, divergent entity (species) (Anderson and Hubricht 1938; Anderson 1949). Introgression is a relative term; alleles at one locus introgress with respect to alleles at other loci. That is, for the above definition to be applicable, some portion of the gene pool of each of the hybridizing taxa must remain constant and uncontaminated such that we can actually recognize that 2 distinct gene pools exist."

Nothing about "new" alelles being created via hybridization. Get it yet?

I don't care where they [mutations] ocurr.
Of course you don't; you don't know any better. In fact, you do not seem to know much about basic cell or molecular biology. If you did, you would be able to better express your ideas. As it stands, your characterization of all of this is rather comical in its childishness ("It [mutation] simply rewrites in a new order what already exists as a possibility within the genome." ^_^^_^^_^).
A copying error is only taking what already exists and writing it in a way it was not before. Hence the word copy.... But one that already existed as a possibility, because copying only uses what already exists....
^_^^_^^_^^_^

I suppose I should not expect anything more sophisticated, the level of your understanding of DNA replication, gene expression, etc. is below the high school level, as best I can tell.
You are really claiming that all mutations already exist? Do you actually believe the things you wrote, or are you just purposely being annoying?

It was already a possibility Tas. A G was replaced by a T, and a T already exists.
And that has what to do with your repeated "transcribing it into an order it was not originally in" nonsense? All of the nuceotides "already exist". What "order", and why mention "transcription"?
What do you think you are proving? WHY was it 'already a possibility'? I find it fantastic that you are so 'well, all possible mutations are already a possibility because they already exist' when confronted with the fact that you do not seem to understand the basic processes that occur in cells, while in other contexts you are adamant that NO mutations occur at all, or if they do, they are all bad, or whatever. It is almost comical.

Almost.

In fact, you contradict yourself on this concept all over the place. A few examples:

"Mutations do not prove past similarity, they instead prove past dissimilarity."

How is this possible if mutations are just 'copy errors' that 'already exist'?

"So in developing an eye the body keeps these useless mutations until the point where it becomes functional? Expends energy keeping alive what until the entire process is complete what is useless on its own?"

That one is especially pertinent - I mean, if all mutations already exist (even as 'possibilities'), then how is this a bad thing?

"If random mutations caused the separation of races, then they should have random junk DNA from those random mutations."

That one is fractally wrong, but whatever...

And so on...

It could just as easily been incorrectly copied with any letter. And all already exist as possibilities....
I don't think you understand the difference between something 'existing' and something being a possibility. And I still see that you do not seem to understand that DNA is not 'letters'. And it also appears that you think DNA are just 'copied' willy-nilly from free floating nucleotides. Or something. It is all just gibberish, when you peel away the mock indignation.
Apparently more than you who are still arguing that alleles passed through introgression are mutated alleles....
Amazing. What do you think they are?
Having copy-pasted your special quotes all these times, you apparently have not once bothered to actually understand any of them.

It should have been obvious from the context of even that paper you linked what introgression is. You seem to think that it 'produces' new alleles, but it merely introduces new ones to a population. And where do 'new alleles' come from? Well, for about the 20th time, from one of your quotes, we see very clearly what the source of these new alleles is - yet this particular instance is a sad rarity. For in it, we see the strange workings of the Dunning-Krugerite mind in action:

Yes, I understand you don't understand what is said, but only see what you want to.

"We may add one more difference between a mutated allele and one introduced by hybridization. The mutated allele has been altered randomly, whereas the one [allele] introduced by hybridization has been shaped by natural selection, albeit in a differentiated genome (deleterious mutations have been purged and any beneficial mutations gone to fixation by selection)."

In other words a genome in which deleterious mutations have been purged and any beneficial mutations already gone to fixation. Therefore the new allele is not the mutated allele, all mutations have been deleted or fixed already.​

Incredible, isn't it? I am accused of only seeing what I want to see in that quote, and then the creationist merely bolds only the parts that he thinks helps his cause (seeing only what he wants to see, almost literally), whereas it is plainly obvious from the quote that the 'introgressed' allele is the one that has already been purged of deleterious mutations, fixed the beneficial ones, and been 'shaped by natural selection.'

I literally cannot understand what the creationist is trying to do on this issue. He is clearly wrong, yet persists in providing the same 'arguments' in which he believes he is right over and over.

Introgression or introgressive hybridization is the incorporation (usually via hybridization and backcrossing) of alleles from one entity (species) into the gene pool of a second, divergent entity (species).


And replication is simply producing two identical replicas of an original.

LOL!

And what if one of the copies is NOT identical to the original?
You know, like what happens EVERY TIME DNA replication happens?
.. Transcription copies the DNA into RNA, Replication copies DNA into DNA.

You are copying what already exists and simply make an error in the copying process.... The combination which is already possible.

What 'combination'? Who ever said it was NOT 'possible' (besides you, in a way)?

It has everything to do with copying. TWO DNA are copied from one original DNA....

Yes - during replication. Not transcription - do you really think those two processes are the same thing?
I know they alter the sequence of the mRNA that was supposed to be made and hence affect the polypeptides....
And how do they alter mRNA sequence, do you think?
Not sudden? It happens at the moment conception starts and those DNA are being replicated.

Wow - you are totally conflating and confusing things here. You had written:
"Don’t try to play your I am suddenly ignorant games and can’t conprehend..."

to which I replied:

"It is pretty obviously not a game, and there is no suddenness to it at all."

and it had nothing to do with conception. My gosh...
You have documented your own erroras time and again and every time I seem to have to correct them.

That is so weird how that has totally never happened.

Surely, if in you fantasies this really happened, you can provide a clear cut example?

Which is why in the end you always bring up your only major claim... a spelling error on my part, because that's all you have....
Actually, I have refuted pretty much every claim you have made. And it is not 'spelling errors', it is conceptual errors and your obvious lack of familiarity with the very topics you are arguing about. AND your inability to admit to even trivial errors.

The ONLY thing I listed that was a "spelling error" [sic - I don't consider it a spelling error when you kept doing after I had corrected you a dozen times] was the "allie" thing - the others are just... you being you - completely erroneous gibberish, false accusations, etc.:

I am not the one that claims new alleles are produce via reproduction/hybridization. I am not the one that thinks the title of a book about a guy researching his family history proves that a certain term is a scientific term. I am not the one claiming that hybridization produces variation from a non-variable breeding pair. i am not the one claiming that the word "mutated" does not appear in a quote that I presented that clearly does contain the word "mutated."
But you have your fantasies to live out, I suppose.

Case in point.... Your only real claim to error is a simple spelling error....

I know, because you refuse to admit the truth that it is introgression which causes it, the backcrossing with the parent subspecies, not a mutation which would not need another subspecies to be passed.......

What is the backcrossing you refer to? I mean, I know what it means, I know what introgression is, I know where new alleles come from, etc., but this part of your sentence:

"the truth that it is introgression which causes it, the backcrossing with the parent subspecies," makes no sense.

And you still just refuse to accept where those new alleles came from, even when your own sources define them as having been mutants processed via natural selection.

Except every time we only end up documenting your errors except for my simple spelling error.....


Only 1 of these was a spelling error:

I am not the one that claims new alleles are produce via reproduction/hybridization. I am not the one that thinks the title of a book about a guy researching his family history proves that a certain term is a scientific term. I am not the one claiming that hybridization produces variation from a non-variable breeding pair. i am not the one claiming that the word "mutated" does not appear in a quote that I presented that clearly does contain the word "mutated."


There are many others I could have mentioned that have nothing to do with your bad spelling, but rather your layman's level of understanding of things that you try to argue on as an 'authority'.

Totally ignoring the entire post because it showed your ignorance and refusal to accept your error. You can't handle the truth because the truth makes your beloved mutations superfluous.....

Introgression. look it up and study it......

This is a rather inane dodging rant. I made no error - I simply documented your false accusation. I did not address your naive, silly 'argument' premised on your inability to understand the material you want to try to 'argue' about. Presented in its entirety:

Wow, this is fantastic - unable to accept his own errors, justatruthseeker attempts to accuse me of, I guess, doctoring a quote - a quote HE originally presented.... Incredible!-
No, no, that’s your fallacious rendering, which their conclusion showed as invalid.

So let’s use your fallacy.

The word mutated does not exist in the original. But we will pretend this is the correct interpretation.

Seeing as how justa refers to "their" quote, he can only be referring to this quote:

"We may add one more difference between a mutated allele and one introduced by hybridization. The mutated allele has been altered randomly, whereas the one introduced by hybridization has been shaped by natural selection, albeit in a differentiated genome (deleterious mutations have been purged and any beneficial mutations gone to fixation by selection)."


Please note that he has claimed that the word "mutated" is not in the original quote.

HERE is the source of the quote:

Here is the quote, with additional context (quote in question in italics):

One possible outcome of hybridization is that the introgression of selectively favoured alleles from one population into the other can bring together new adaptive combination of alleles that increase diversification. Abbott et al. (2013) make a five‐point argument for why hybridization may enhance adaptive differentiation. In short, they argue that hybridization may act as a possibly more abundant source of adaptive genetic variation than mutation because mutations are rare and hybridization common. They cite Grant & Grant (1994) who estimated that the amount of new, additive genetic variance introduced by hybridization was two to three orders of magnitude higher than that introduced by mutation in Darwin's finches. We may add one more difference between a mutated allele and one introduced by hybridization. The mutated allele has been altered randomly, whereas the one introduced by hybridization has been shaped by natural selection, albeit in a differentiated genome (deleterious mutations have been purged and any beneficial mutations gone to fixation by selection). Intuitively, I would therefore think that an allele introduced by hybridization on average is more likely to do something good for the organism it enters than a mutated one. The relative distribution of fitness effects of mutated versus introgressed alleles is an interesting empirical question that should be investigated further. Moreover, not only single alleles, but co‐adapted suites of interacting genes could potentially be transferred through introgressive hybridization, leading to rapid origin of complex adaptations and evolutionary novelties. Introgression as a source of new genetic variation is by definition not available for completely reproductively isolated species.​
HERE is the earliest use of this quote I could find using the search feature of this forum - posted by justatruthseeker on July 19, 2018:

"...They cite Grant & Grant (1994) who estimated that the amount of new, additive genetic variance introduced by hybridization was two to three orders of magnitude higher than that introduced by mutation in Darwin's finches. We may add one more difference between a mutated allele and one introduced by hybridization..."​
In fact, it is most interesting that justa decided to truncate the quote where he did, for the very next sentence EXPLAINS that the newly introduced allele was the product of MUTATION followed by selection:

"The mutated allele has been altered randomly, whereas the one introduced by hybridization has been shaped by natural selection, albeit in a differentiated genome (deleterious mutations have been purged and any beneficial mutations gone to fixation by selection)."

So this is your interpretation.

No, this is the interpretation of the authors that YOU have cited and quoted many times.

Rarely is your dishonesty so blatant, but I do find your accusation to be malicious and unwarranted, and the product of desperation and mendacity.

Reported.​
It should be obvious that I did not even attempt to refute your crazed ranting, I merely refuted your false accusation.

How can it get any worse?

Yes, I asked myself that question before. I didn't think it could get any worse. But yet, here we are.

You already slagged the Bible's morals.
You already said the Douay and King James are the same.
The only way it can get worse from there is to become a scientist.
Those evil, evil scientists.

On that note, why are you using that pc? It's a product of evil scientists!
