Do you include adaptation in that?
Quit confusing adaptation as evolution. We agree a billion black rabbits placed close to the north pole if they survive will in time become white rabbits. Part of what God put in the DNA to enable animals to survive. But alas, they will still be rabbits and will always be rabbits.

Lots of 'new DNA' arises DURING copying.

Surely, one who claims others need to learn some biology understands how things like duplications and insertions occur?

Show me ONE instance of new DNA arising at any time??????? Duplications? Do you mean the copying of what already existed? Insertions? Do you mean inserting in a new place something that already existed? Apparently you fail to understand the difference between a T copied out of order and a T being created where the T never existed before. Not sure you understand what is meant by the term DNA. Not new allies, that are merely copies in a new order of what already exists, but DNA letter sequences that never existed before. This is a requirement in simple to complex, yet has never even been hinted at that it is possible.

He's right though.
It's how hereditary diseases emerge.
The "new" there is that the data is corrupted and not corrected.

A mutation resulting in a DNA sequence that is a new allele is by definition a new DNA sequence.

Or to use your own words, "a new order of what already exists" is a new DNA sequence.

That's rather beside the point. The fact that you're willing to claim that populations of organisms with as much as 80% genetic variability between them are the "exact same", yet for some reason claim that other populations with maybe a 0.1% difference between them are fundamentally different shows how arbitrary your entire argument is.

I'm not making that claim, your own evolutionists admit they are the same species. Don't blame me for what they know to be true. Asians have a huge variation between members of that group, yet they remain Asian. Are you saying we should classify Jung as a separate species than Yung? I dont think your own evolutionists would accept that. Why not call Africans a separate species from Asians then? Ahh, you dont want to do that since we aren't bacteria, yet see no problem trying to imply such diversity in bacteria might make them separate........ I sense a lack of true conviction of belief....

Its not "new". It is simply what already existed copied into a new format. They wish to try to confuse the line between allies and DNA to the uninformed.

If i copy C,T,G,A as G,T, A, C no new DNA was created. Just what already existed was copied either incorrectly causing a birth defect, or just happened to work enough to get by. C, T, G and then with A made where it didn't exist before would be new DNA.

He is wrong, he is trying to deliberately blur the line between what DNA is and what allies are, knowing the difference, or at least he should.

Or to use your own words, "a new order of what already exists" is a new DNA sequence.
No, an allie is simply a very small portion of what DNA is. You ask that I start with C and end up with C,T,G,A. I ask you to prove this is even remotely possible. Your only response is to attempt to tell me that the same letters copied into a different sequence is the same as adding a letter where it could not have existed before. Take that elsewhere, it doesn't fly and never will except in the minds of those that need to believe that copying a DNA letter that already exists equates to being the same as a DNA letter existing where it did not exist before. There is no comparison. Nor has any mutation ever created a new letter sequence. You require this. It is you that asks i start with a simple DNA and make new DNA where it never existed before. I simply ask you start with everything you see and simply change sequences, which is supported by all of genetics.

Arguably, every single organism has DNA unique to them. However, this doesn't answer what would prevent DNA changes via evolutionary mechanisms from creating subsequent biodiversity.

Because DNA can only work with one pattern.
The DNA that makes hair may be similar to that
which makes scales or fur, but it cannot make them
any more than a dog can grow wings or gills. DNA is
conservative, geared toward staying the same, not
gathering new information or changing functions.

If you're talking about adding a new nucleotides to a sequence, we already know that occurs. It's called an insertion mutation: Insertion (genetics) - Wikipedia

This is well known and documented.

That's not really true though given the multitude of DNA sequences observed in nature.

which makes scales or fur, but it cannot make them
any more than a dog can grow wings or gills. DNA is
conservative, geared toward staying the same, not
gathering new information or changing functions.

While DNA has mechanisms for conserving sequences, we already know these mechanisms fail resulting in changes to DNA. And this can and does result in novel DNA sequences, gain-of-function mutations, etc.

I'm not making that claim, your own evolutionists admit they are the same species.

Actually there is debate over bacterial species concepts and classifications given they don't really follow the same rules as other types of organisms.

Asians have a huge variation between members of that group, yet they remain Asian. Are you saying we should classify Jung as a separate species than Yung? I dont think your own evolutionists would accept that. Why not call Africans a separate species from Asians then? Ahh, you dont want to do that since we aren't bacteria, yet see no problem trying to imply such diversity in bacteria might make them separate........ I sense a lack of true conviction of belief....

It has more to do with the fact there are multiple species concepts and the species concept for bacteria is not the same for eukaryotes.

Perhaps if you took your own advice and read a biology book or three, you'd already know this.

What do you mean "new" DNA? Are you really asking aout DNA being conjured from nothing?

Duplications? Do you mean the copying of what already existed? Insertions? Do you mean inserting in a new place something that already existed? Apparently you fail to understand the difference between a T copied out of order and a T being created where the T never existed before.

How else do you propose 'new' DNA 'arising'?

You are arguing a strawman and apparently do not have sufficient high school - level biology know it.

Not sure you understand what is meant by the term DNA.


Not by the way you are using it, apparently not.
Not new allies, that are merely copies in a new order of what already exists, but DNA letter sequences that never existed before. This is a requirement in simple to complex, yet has never even been hinted at that it is possible.

So you are 100% ignorant of how genomes evolve - and here you are implying that I do not even know what DNA is.

You really need to drink a big old jug of humility and look up "the Dunning-Kruger effect."

So.... The gene for the protein cytochrome c, found in all vertebrates, can differ by as much as 80% in its DNA sequence in different taxa, yet they all produce a functioing protein.

Explain that if DNA can only use 1 pattern?

the same DNA letters copied into a new format as equating to the creation of DNA letters that did not exist before.
This is well known and documented.

Agreed, what already existed was inserted where it was not before. Yet it is you that insists we start with just a few letters of the DNA strand and then make more letters where they did not exist before. No, even worse, that these few letters not only make more, but become all brand new letters different from the original.

I didnt ask you to show me that a C can be inserted between a T and G where the C already existed, but that a C can exist where C never existed at all in the entire genetic strand. This is what your theory requires. Support your theory. Not with things that already exist, but the addition of new letters that never existed before. I am not the one that requires this to happen. I require only what we see. The same DNA letters copied into the same format, different formats, or inserted into new places. All this supports my contention and assertions, not yours. You simply reaffirm what I have said over and over again without realizing it. Confusing the copying or insertion of DNA letters that already existed into a new order or new place, as meaning the same as a new DNA letter existing where that letter did not exist before in the DNA strand. There is no comparison. Convince me a C can be made where a C never existed in the entire genetic strand before?

Hey, its ypour theory, simple to complex. I already know it was created from preexisting matter - dust.


How else do you propose 'new' DNA 'arising'?
Its your theory, convince me it has merit. Its evolutionists that insist it is possible. Are you saying its not?

You are arguing a strawman and apparently do not have sufficient high school - level biology know it.
My biology is quite sufficient, which is why you know you cant explain the creation of new DNA letters with any plausibility, which is why you revert to the attempted strawman argument, when your attempt at trying to convince me C,T,G,A copied into a new format was the same as making C where it didnt exist before.


Not by the way you are using it, apparently not.


So you are 100% ignorant of how genomes evolve - and here you are implying that I do not even know what DNA is.

You really need to drink a big old jug of humility and look up "the Dunning-Kruger effect."
You have failed to make your case. I asked you to explain how a C arises in the DNA strand where it never existed before in the strand. Simple to complex. If you have no answer say so and stop trying to blame others comprehension because yu lack the science to explain what is impossible and never once observed.

I'm glad that you ignore 90% of what people write so you can pretend that it is just a spelling error.

Allie - what was it you wrote to me - that I need to learn some biology?

And you talk about 'allies' and 'genetic strands' and Cs popping into existence from nowhere..

Just goes to show the lack of any plausibility when instead of debating the facts evolutionists turn to ad hominem attacks because of spelling errors.


How on earth is pointing out that you don't know what an allele is an ad hominem?

Do you even know what an ad hominem is?

It is RELEVANT that a person does not understand the basics about an area that THEY claim to be debating - is it not?




Here are some facts that all of the creationists on this forum that have replied to have just omitted the entirety of this and focused on my introduction:

Actually, it is based, for me, on things like this list I came across elsewhere:

Anat Rec. 1977 Aug;188(4):477-87.
Sperm/egg interaction: the specificity of human spermatozoa.
Bedford JM.
Abstract
Human spermatozoa display unusually limited affinities in their interaction with oocytes of other species. They adhered to and, when capacitated, penetrated the vestments of the oocyte of an ape--the gibbon, Hylobates lar--both in vivo and in vitro. On the other hand, human spermatozoa would not even attach to the zona surface of sub-hominoid primate (baboon, rhesus monkey, squirrel monkey), nor to the non-primate eutherian oocytes tested. Among the apes the gibbon stands furthest from man. Thus, although the specificity of human spermatozoa is not confined to man alone, it probably is restricted to the Hominoidea. This study also suggests that the evolution of man and perhaps the other hominids has been accompanied by a restrictive change in the nature of the sperm surface which has limited and made more specific the complementary surface to which their spermatozoa may adhere. For the failure of human spermatozoa to attach to the zona surface of all non-hominoid oocytes stands in contrast to the behaviour of spermatozoa of the several other mammals studied which, in most combinations, adhered readily to foreign oocytes, including those of man. Taxonomically, the demonstration of a compatibility between the gametes of man and gibbon, not shared with cercopithecids, constitutes further evidence for inclusion of the Hylobatidae within the Hominoidea.
Amino acid sequence data also supported the close affinity of humans-chimps-gorillas in 1985 (and earlier) -

"PHYLOGENY OF PRIMATES AND OTHER EUTHERIAN ORDERS: A CLADISTIC ANALYSIS USING AMINO ACID AND NUCLEOTIDE SEQUENCE DATA"
Abstract— Genealogical reconstructions carried out by the parsimony method on protein amino acid and DNA nucleotide sequence data are providing fresh evidence on cladistic branching patterns at taxonomic levels from the classes of Vertebrata and orders of Eutheria to the genera of Hominoidea. Minimum length trees constructed from amino acid sequence data group Mammalia with Archosauria (i.e., Aves plus Crocodilia), Amniota with Amphibia, and Tetrapoda with Teleostei. Within Mammalia, Edentata and Paenungulata (e.g., Proboscidea) appear as the most anciently separated from other eutherians. Another superordinal eutherian clade consists of Artiodactyla, Cetacea, and Perissodactyla. A third consistently contains Primates, Lagomorpha, and Tupaia. The cladistic positions of such orders as Carnivora, Chiroptera, Insectivora, and Rodentia are not well resolved by the currently still sparse body of sequence data. However, recent dramatic progress in the technology of gene cloning and nucleotide sequencing has opened the way for so enlarging the body of sequence data that it should become possible to solve almost any problem concerning the phylogenetic systematice of extant mammals. An example is provided by hominoid genera. Minimum length trees constructed from mitochondrial DNA nucleotide sequence data very strongly group Pan, Homo, and Gorilla into Homininae and then join Homininae and Ponginae (pongo) into Hominidae as the sister family of Hylobatidae (Hylobates). Resolution of the hominine trichotomy into two dichotomous branchings should be forthcoming as kilobase sequencing of nuclear genes progresses.
And of course DNA sequence data has been the icing on the cake - starting with analyses of the entire single-copy genome -

J Mol Evol. 1990 Mar;30(3):202-36.
DNA hybridization evidence of hominoid phylogeny: a reanalysis of the data.
Sibley CG1, Comstock JA, Ahlquist JE.

Abstract
Sibley and Ahlquist (1984, 1987) presented the results of a study of 514 DNA-DNA hybrids among the hominoids and Old World monkeys (Cercopithecidae). They concluded that the branching order of the living hominoid lineages, from oldest to most recent, was gibbons, orangutan, gorilla, chimpanzees, and human. Thus, a chimpanzee-human clade was indicated, rather than the chimpanzee-gorilla clade usually suggested from morphological evidence. The positions of the gibbon and orangutan branches in the phylogeny are supported by substantial evidence, but whether the chimpanzee lineage branched most recently from the human lineage or from the gorilla lineage remains controversial. The conclusions of Sibley and Ahlquist (1984, 1987) have been supported by several independent studies cited by Sibley and Ahlquist (1987), plus the DNA sequence data of Hayasaka et al. (1988), Miyamoto et al. (1988), Goodman et al. (1989, 1990), and the DNA-DNA hybridization data of Caccone and Powell (1989). The laboratory and data analysis methods have been criticized by Marks et al. (1988) and Sarich et al. (1989). In response to these critics, and for our own interests, we present a reanalysis of the Sibley and Ahlquist data, including a description of the corrections applied to the "raw counts." The validity of the laboratory methods is supported by the congruence of tree topology and delta values with those of Caccone and Powell (1989), although their tetraethylammonium chloride technique differs from the hydroxyapatite method in several respects. The utility of the T50H distance measure is indicated by its congruence with percent sequence divergence at least to delta T50H 30, as noted by Goodman et al. (1990). The Sibley and Ahlquist uncorrected data indicate that Pan is genetically closer to Homo than to Gorilla, but that Gorilla may be genetically closer to Pan than to Homo. Melting curves are presented for the pertinent experiments, plus one that includes representatives of most of the groups of living primates.
Chimpanzee genome paper:


Nature 437, 69-87 (1 September 2005) |
Initial sequence of the chimpanzee genome and comparison with the human genome
Nucleotide divergence

Best reciprocal nucleotide-level alignments of the chimpanzee and human genomes cover ~2.4 gigabases (Gb) of high-quality sequence, including 89 Mb from chromosome X and 7.5 Mb from chromosome Y.
Genome-wide rates. We calculate the genome-wide nucleotide divergence between human and chimpanzee to be 1.23%, confirming recent results from more limited studies12, 33, 34. The differences between one copy of the human genome and one copy of the chimpanzee genome include both the sites of fixed divergence between the species and some polymorphic sites within each species. By correcting for the estimated coalescence times in the human and chimpanzee populations (see Supplementary Information ‘Genome evolution’), we estimate that polymorphism accounts for 14–22% of the observed divergence rate and thus that the fixed divergence is ~1.06% or less.
And sundry other papers/sources using DNA sequence data:


10kTrees Website: Dataset

The 10k trees project (link above) used highly conserved sequences (e.g., ribosomal subunit genes, cytochrome b, etc.) from hundreds of primate species and constructed a massive phylogeny, showing human-chimp kinship to the exclusion of gorilla.



"A Molecular Phylogeny of Living Primates"
Hominoidea

Once contentiously debated, the closest human relative of chimpanzee (Pan) within subfamily Homininae (Gorilla, Pan, Homo) is now generally undisputed. The branch forming the Homo and Pan lineage apart from Gorilla is relatively short (node 73, 27 steps MP, 0 indels) compared with that of the Pan genus (node 72, 91 steps MP, 2 indels) and suggests rapid speciation into the 3 genera occurred early in Homininae evolution. Based on 54 gene regions, Homo-Pan genetic distance range from 6.92 to 7.90×10−3 substitutions/site (P. paniscus and P. troglodytes, respectively), which is less than previous estimates based on large scale sequencing of specific regions such as chromosome 7 [50].



Feel free to pick one of those and I will debate its merits with you.

Explain that if DNA can only use 1 pattern?
Lets understand it is not the same at all.

It belongs to the cytochrome c family of proteins.

That you might confuse an entire family of proteins as being the same, might be the start of the problem.

And here I thought you wanted to label all those sub members of the same family as separate. I stand corrected. It now appears you wanted to label sub members as being the same.
