Your slavey red-herring is yet another travesty. Start a thread on that if you want to. This thread is on the unscientific nature of D’s T of E and you are losing

Be fair – it was @buffalo who brought up the notion of “holding on to old paradigms for too long”. He opened the door… @rossum merely stepped through it. 😉

It is how you are defining macro-evolution.
How do you define macro evolution?
Ooh! Can I play this game? “Buffalo defines macro-evolution as ‘the attempt by science to deny God’.” How’s that? 🤣
 
The ancestors are not unknown, they are a different species of crayfish. Probably Procambarus fallax .
Not according to Biol. Stephan Scholz, Biologist at Universität Rostock. All agree that the ancestors are unknown. Scholz, as I cited, believes Lyko’s interpretation as “highly speculative.”
Do not read too much into the language used in science papers. Every scientist knows that all scientific hypotheses and theories are provisional, and the language they use shows this.
Do not paraphrase too much the language used in science papers to elevate what is offered as provisional to be fact, especially when peers report skepticism of even the provisional claim.
What evidence do you have to show a different non-macro-evolutionary origin of the Marbled Crayfish? Evidence counts in science; personal opinions count for a lot less.
Your bias is showing. Follow your own instructions on promoting personal opinions as science facts.

Two points.
  1. Lyko offered no evidence that speciation occurred, only speculation (i.e., personal opinion).
  2. Non-macro evolution is the default position until evidence is produced. Otherwise, the assignment is to prove the negative which is impossible.

All scientific theories are provisional. Facts are not, but theories always are. Newton’s theory of gravity was provisional and was replaced. That is the way science works. We use the best information we currently have. As and when more information comes in the theory will be adjusted or replaced as required. Darwin was not aware of Mendelian genetics. When Mendel’s work was rediscovered Darwin’s original theory was adjusted to incorporate Mendel.

A great deal of science is provisional. Both Quantum Mechanics and General Relativity are provisional. Scientific papers reflect the provisional nature of science.

Biologists may disagree on what other species of crayfish the Marbled Crayfish evolved from, but they do not disagree on the fact that it evolved from an earlier species of crayfish. It is still an example of macro-evolution.

We know all that. But there are scientific facts – overwhelming confirming data and all experts in agreement. Macro-evolution does not approach that status.

All agree that the Marbled Crayfish is different than non-Marbled Crayfish. You may call the Marbled Crayfish a different specie (once you define the term “specie”). What is not evidenced is that the Marbled Crayfish is a new specie (again depending on a definition of “specie”).

This example of Crayfish evidences the steamrolling technique (confirmation bias) used by adherents of evolutionism to use yet unproven theories as if they were science-facts to promote novel claims.
 
Would it be so bad to just be able to leave it where the facts stop? The facts are inconclusive - they may indicate or suggest macroevolution, but it has yet to be proven. Claiming it is fact is silly, and its just as silly to claim that there is no basis for believing it. One can argue why they thing the evidence is compelling or why they’re dubious about the evidence, but to start bickering about how “its so true and you’re dumb to think it isn’t” or “you’ll just believe anything put in front of you” doesn’t help anybody and doesn’t change anybody’s minds about a single thing.

Of course the theory is scientific - making a guess as to what may be true. “Micro” has been proven to be true, but one aspect, “macro,” has not yet. You could call it a working hypothesis. Still scientific, still far from proven, still far from disproven.

Its not good to act as though its known to be either absolutely true or absolutely not and that we have all the answers - we just don’t know, and while we may someday, its okay that we don’t right now.

That’s very reasonable, but the problem is that the same could be said for any scientific theory, and that would not be a useful position. We can’t sensibly sit back and say “we just don’t know whether any scientific theory is true, but we may some day.”

Once a theory is strong enough in the face of the evidence to be accepted by the scientific community, the sensible thing is for us — the folk at large — to accept it, too, until evidence turns up which the theory cannot be reconciled with. Then it can be amended or discarded.
 
I agree with your sentiment, but it doesn’t seem like that would apply to that many ideas. This macro evolution, certainly, but most others are either well known to be true, well known to be false, or too new to know. Few theories are in the position this one is, which is why we ought to stop testing it as though it’s definitively in one camp
 
We know all that. But there are scientific facts – overwhelming confirming data and all experts in agreement. Macro-evolution does not approach that status.
Your sources are incorrect. Macro-evolution does reach that status. Darwin’s book was called “On the Origin of Species”. Since macro-evolution is how species originate, then obviously macro-evolution id basic to the theory, and is very well supported. If there was no macro-evolution then there would be no new species, and we would find fossil horses in hte Precambrian. We do not, so horses must have originated by macro-evolution since the Precambrian.
What is not evidenced is that the Marbled Crayfish is a new specie (again depending on a definition of “specie”).
It was first observed recently and not in the wild but in German aquariums. It is a new species, or do you have a fossil Marbles Crayfish from the Precambrian? Crustaceans fossilise very well because they have hard shells.

Yes. Because then we would have to dump all scientific theories. Theories are not facts, and can be changed when necessary. Newton’s Gravity was not a fact, and it was changed when shown to be in (small) error. You would have us not even start to use the theory, which is still useful where the small error is too small to make a difference.

If you want facts, then there are no horse fossils in Precambrian, or earlier, rocks: fact. Horses exist today: fact. Therefore horses originated some time between the Precambrian and today: deduction. Would you have us reject the deduction? After all, deductions are not facts.

Look at just about any pro-evo paper. This is the language you will see:

It is thought
Perhaps
Might be
Could be
Could have
Might have
etc
and on and on…
 
We use the best information we currently have.
Which support intelligent design.

Genetics and epigenetics are leading the way. They are proving to be more accurate than the old way of classifying species by morphology, We are finding “species” are very specific and the distance that has to be covered between them is greater than thought. Draw a circle around them and they will not cross that boundary no matter how many random mutations or natural selection pressures.
 
“macro,” has not yet. You could call it a working hypothesis. Still scientific, still far from proven, still far from disproven.
It is being disproven -

It is textbook biology, for example, that species with large, far-flung populations—think ants, rats, humans—will become more genetically diverse over time.
But is that true?
“The answer is no,” said Stoeckle, lead author of the study, published in the journal Human Evolution .
For the planet’s 7.6 billion people, 500 million house sparrows, or 100,000 sandpipers, genetic diversity “is about the same,” he told AFP.
The study’s most startling result, perhaps, is that nine out of 10 species on Earth today, including humans, came into being 100,000 to 200,000 years ago.
“This conclusion is very surprising, and I fought against it as hard as I could,” Thaler told AFP.

“another unexpected finding from the study—species have very clear genetic boundaries, and there’s nothing much in between."

“If individuals are stars, then species are galaxies,” said Thaler. “They are compact clusters in the vastness of empty sequence space.”

A bit off topic but illustrates your point.

As historians, the ancients attempted to explain natural phenomena not by analysis but by action which required they use story or myth. Myth was serious business; they did not intend these stories to be merely entertainment. They were recounting events upon which their very existence depended. Through myth, the ancient historians put order into apparent chaos. The myth or interpretation of reality followed the observation of the natural phenomena. Ancient historians, like their modern counterparts, used inductive reasoning. They produced their myths after examining the natural phenomena. If the myth stood the test of coherence and gave meaning to the phenomena, it endured passing from generation to generation.

The only difference between the ancient myth makers and evolution is the former asked, “Who?” and the latter asks, “How?”.
