I can't deal with all your hot air right now, but a few comments:
No I am not trying to prove God here. I had some doubts about evolution before I became a believer. I can see how someone could argue against it without believing in any particular religion. In my case, yes, it was Christian Creationism that really got me into it. But I think evolution is wrong whether it contradicts Christianity or not. You make false assumptions about my motivations and therefore you don't bother about the arguments involved. No, my arguments are NOT "religiously motived." Evolution is a lie and the scientific arguments will eventually show it. Atheists can appreciate them too. Time can't accomplish something that is in principle impossible. Mutations are going to make changes all over the genome, they aren't going to produce anything coherent enough to form a new species. You are a Schyster as well as a Pisces.

And you are a troll.
Facts don't lie or have an agenda. Facts are just facts "God did it" is not an argument. It is an excuse for intellectual laziness. If your viewpoint has merits and facts to back it up why would you have to lie?

I haven't finished reading to the end of the thread yet, but so far Dredge isn't engaging with any of the information provided to him. I'd like to see him explain how people are wrong in their criticisms of his views, but instead he's just ignoring them, making discussion impossible.
Discussion is obviously not the objective. Some posters are simply not serious.

Sorry, but I don’t understand your question (which is probably due to the facts that I have a fragile eggshell mind and my IQ is only 9). Please demonstrate to us that human breeding of dogs introduced targeted mutations into their genomes. Btw, do you know how to bred ancient “rodents” so that a whale will eventually evolve?

The fact of the matter is, if you don’t know how to breed ancients “rodents” into a whale, you don’t know how whales evolved and you don't know how macroevolution occurs.
Your test doesn't align with the claim. The explanation of your test, however, also begins relatively simply:
Point 1 makes some sense - except you have absolutely no idea how large the rodent population must be. So there’s problem No. 1 for any potential breeding program. If you don’t know how large the initial population must be, this means your knowledge of how macroevolution occurs is based on a certain degree of ignorance and guesswork.1. Start with a very large population of rodents - equivalent to that when such rodents roamed the earth. 2. Provide an environment equivalent to that when such rodents roamed the earth. 3. Provide selection pressures equivalent to that when such rodents roamed the earth. 4. Wait for the populations to reproduce and evolve due to selection pressures and mutations. 5. If the progressive evolution of the rodent into a whale isn't matching what occurred the 1 time it previously happened at any point in the "unlimited time" available for the breeding - kill off all creatures and begin again at step 1. -due to the random nature of mutations, this is expected to occur many, many times before it matches the 1 time it previously happened again. 6. Viola - a large population of whales. Points 2-4 are irrelevant - artificial selection means you don’t need to reply on natural selection. If you don’t know how to artificially select the rodents you need to breed them towards whale-ness, this demonstrates that you don’t know how your alleged evolution occurred. Point 5 indicates that you don’t know how an ancient “rodent” evolved to eventually become a whale. You’re just stabbing in the dark and hoping for the best. Point 6 indicates that your so-called knowledge of whale evolution and how macroevolution occurs is childishly simplistic, based on blind faith and pseudo-science.

Whatever. You’re splitting hairs - some articles describe the evolutionary ancestors of whales as a “rodent-like creature”. And I realize that this ancestral creature (whatever it is) is extinct.
whales didn't evolve from rodents but from a now extinct ungulate (a hoofed animal), i.e., it no longer exists Second, even if this ungulate did exist, because mutations are random repeating the experiment is unlikely to produce whales . Third, even if this original ungulate did exist, we couldn't keep it unchanged from one run of the experiment to the next because it would evolve too. The only way to actually run the experiment is to begin with an infinite number of ungulates and run an infinite number of these experiments simultaneously.
If you don't know how to breed whales from their ancestral “rodents”, you don't know how whales evolved nor how macroevolution occurs. Can you even explain how the first step in such a breeding program? How are you going to bred these landlubber “rodents” such that a large enough population of them live permanently in the ocean?
And Fourth, we don't know the details of the changing environments that occurred in sequence, including the now extinct plants and creatures that populated them. Even if we did, they don't exist anymore. That is, we don't know what the selection pressures were, and even if we did we couldn't reproduce them.
You don’ need to know what the ancient environment was like and you don't need selection pressures - in the proposed breeding program the necessary features are selected artificially, not naturally. If you dont know which "rodent" features to select, then you don't know how whales evolved.
Since breeding leaves mutation out of the equation you are absolutely right that there are limits to the degree of changes breeding can effect. I don't understand this. Breeding leaves mutations out of the equation? Aren’t mutations responsible for the natural variations in dogs, for example, which breeders have exploited to produce hundreds of different breeds? Dog breeders also induce unnatural mutations via inbreeding, which are also selected.
Dredge writes: Mutations. For instance, wolves were bred to produce many different breeds of dogs, but harmful mutations limit how far this process can be taken. How can these genetic limitations be overcome to breed a whale from a sort-of-rodent? Oh, do you mean the imaginary species-vaulting mutations of Darwinist folklore that thousands of years of animal breeding has no evidence of? Edited by Dredge, : No reason given.

It's common knowledge: Dredge writes:
You have never supported this assertion. For instance, wolves were bred to produce many different breeds of dogs, but harmful mutations limit how far this process can be taken. "Health and welfare problems in pedigree dogs can arise as a result of the deliberate selection for exaggerated physical features or as a result of inherited disease. While some of the following problems can occur in any breed, cross breed or mixed breed dogs, purebred pedigree dogs are at greater risk and appear to be over-represented clinically. This is mainly due to traditional breeding practices.Difficulty breathing Difficulty giving birth Difficulty walking Serious eye problems Serious skin problems" Page Not Found | RSPCA Australia

It is overcome by selection over millions of years. How can these genetic limitations be overcome to breed a whale from a sort-of-rodent? "In his recent book, The Greatest Show on Earth: The Evidence of Evolution, Richard Dawkins observes airily that human beings are "distant cousins of bananas and turnips." Yet minutely observant plant breeders, "daily and hourly scrutinizing" their productions (to quote Darwin on natural selection), are unable to turn purple roses into blue ones." (Tom Bethell, Natural Limits to Variation, or Reversal to the Mean: Is Evolution Just Extrapolation by Another Name, evolutionnews.org) "The available data of biology indicates that in contrast to evolutionary theories, there is sufficient evidence to suggest that biological change has limits."

Not necessarily. In other words, we would need to take millions of years to replay the evolutionary history. "In just 26 generations, we managed to create relationships between the shape and size of (fruit) fly wings that were more extreme than those resulting from more than 50 million years of evolution." - Geir H. Bolstad, researcher at the Norwegian for Nature Research. (sciencedaily.com, "58,000 fruit flies shed light on 100-year old evolutionary question", 2015) And btw, the OP did say the breeding program is hypothetical.
Thousands of years of breeding is not enough time to produce the needed variation.
Time is not a problem, as we talking hypothetically. Which "rodent" feature would you select first in order to get the breeding program rolling down the road towards whales-ness? Hind-legs fused together to form a tail, perhaps? Edited by Dredge, : No reason given. Edited by Dredge, : No reason given. Edited by Dredge, : No reason given.

This is incorrect. It is not a mutation here and a mutation there. If we use humans as an example, there are on average 100 mutations in every individual in a population. If we take the population of reproducers as 1 billion people, they have a combined 100 BILLION NEW MUTATIONS in just their generation of our population. If you take the whole human population there are 750 BILLION NEW MUTATIONS right now.

No need to - a breeding program relies on artificial selection, not natural selection.
Expandingng on this the process, the implied simulation of the actual known natural history of evolution of whales on earth would entail:... provide an environment similar to, but wetter, than their previous environments select the healthiest survivors, make single genetic changes to each individuals reproductive gametes that would make them closer to the whale genomes available
If you have to rely on genetic engineering to evolve your rodents, you are admitting you don’t know how to breed them in order to eventually produce a whale - in which case you don’t know how whale evolution happened nor how macroevolution occurs.
and breed them randomly
In other words, you don’t know how a whale evolved from a “rodent”. You’re relying on trial’n’error and luck, rather than knowledge.if they are whale-like, then you are done if they are not whale-like, repeat from step 2 if they all perish, start over from the beginning Edited by Dredge, : No reason given.

=FaithMore likely your rodent is just going to get tired of being wet and long since would have emigrated to a more congenial climate.
LOL! But seriously, Faith, haven’t you seen those polar bears that live full-time in the ocean, whose hind-legs have fused together into sort of a tail, whose front-legs look kinda like flippers and whose nostrils have moved to the top of their heads?

Dog breeders use inbreeding to induce unnatural mutations, but I fail to see what any of this this has to do breeding ancient rodents to eventually produce a whale.

Please tell me why you couldn't theoretically breed the alleged evolutionary ancestors of whales - rodent-like creatures - to eventually produce a whale.

Multiply the billions of mutations/generation you mentioned by the thousands of years that humans have been breeding animals and plants ... so we're talikng possibly trillions of mutations in one species ... yet breeeders ALWAYS eventually encounter genetic limits to how much the original organism can be changed.
