Can the history of life on earth be proven to be the result of any natural process?

predictions about what? How they were made? No
How DNA builds specific shapes or organs? No
How a fish turns into a land creature? No

Your predictions mean nothing. All you are predicting is what evidence you want to see. They do not prove one stage of ToE.

You join dots without knowing the way they are joined. You make connections that cannot be witnessed.
You claim ancestry but cannot prove any birth or death is related.
You have static fossils. Dead creatures. With no proof they were successful or failures.
You claim adaptions to environments that have long disappeared.

You really have nothing at all just theories.

Something that’s completely absent from this thread is any alternative proposal.

Sure, we can’t prove Cambrian biota evolved from Ediacaran biota. But its the best available idea we have at present. Nothing else even comes close.

Criticising evolutionary processes as being unknown when we can watch them happening leads to an obvious counter-question: What processes do you think occurred instead, and where can we see proof or the evidence for those, either historically or currently?

It’s obvious that every criticism of evolution you have raised applies at least as much to your own preferred history, and you are being a massive hypocrite.

Unless… please describe the steps involved in the origin of mammals, whether from fish or otherwise, including details of any precursors or other ingredients needed. Then demonstrate that the steps you’ve described are not just a figment of your imagination, but are actually what happened.

What have you got?

Prediction about what we observe, namely the mixture of physical features in fossils and their position in the geologic record.

Then you reject the scientific method.

We construct hypotheses and test them. It’s called science.

What I was thinking of were global abrupt changes, which Darwin definitely didn’t accept (e.g., K-T boundary as a mass extinction event).

Well, would he have any reason to think they occurred? We hadn’t at that time found the iridium layer or the crater.

IIRC when Darwin was writing the geological column had been roughly mapped out and index fossils identified for the various layers, but we didn’t have any timescale, and had only examined a small fraction of the Earth’s geology or fossils.

Was there any theory of global abrupt changes for him to reject?

(I’m not saying there wasn’t, only that I can’t think of one).

Of course.

Evolution proponents are requested to describe in detail and provide proof of changes that happened millions of years ago.

Creation proponents just type three letters.

Massive hypocrisy is an understatement.

Period catastrophism did exist and was, if anything, more popular than Lyell and Darwin’s extreme uniformitarianism. What the mechanism was for catastrophes wasn’t really known, but large floods and desertification were among the ideas around. The K-T boundary having more abrupt faunal changes than a lot of other pairs of adjacent layers was known by then, but whether than meant missing layers or some abrupt global event was uncertain.

Darwin’s guesses for absolute ages of layers were much higher than his contemporaries, and were almost all too high (Quaternary as tens of millions, Cenozoic as a few hundred million, Phanerozoic as 2.5 billion are the specific ones that I remember).

Looks like I have some research ahead…

Some of the books by Martin Rudwick on the history of geology are a good resource for summarizing such things.

You do not do anything or expeirment.

if I mix a, with B?

You can predict and prove, or deny. (That is scientific methodology)

There is not such predictions in ToE

You cannot do, and repeat. You only observe static data.
(unless the creature is alive :innocent:)

Observations are another perfectly valid way to corroborate or refute hypotheses, and are the standard option for organismal biology, paleontology, astronomy, ecology, etc., etc.

It’s not as if we can create a few square miles of taiga with precisely controlled conditions and observe how moose behave in each one of these; what can be done is to find and observe.

If I dig in this rock formation?

If I compare the genomes of these two creatures?

If I look for an impact crater this old?

If I measure the ratio of argon isotopes in this ancient lava flow?

If I check these fossils for faint outlines of feathers?

If I date these two fossil-bearing rocks?

If I generate stripe-markings from this chromosome from one species and these two separate chromosomes from another?

If I sequence the same protein from these three species?

If I generate tree diagrams for these animals based on (i) morphology and (ii) genomes?

If I look for this species on that continent?

That’s a lie. You know better.

We make predictions about which mixtures of features we should and should not find in fossils.

The experiment is comparing those predictions to the fossils themselves.

Here are 29 of them:

We can repeatedly compare fossils to the predictions about them, and continue to find new fossils. The physical data from fossils is repeatable which meets the requirement of the scientific method. You don’t repeat the hypothesis or theory.

So you can’t do it right, and justify what you do.

Okay

That is not an experiment in the accepted sense.

You ae trying to join dots, and making assumptions that cannot be proven or confirmed in any other way

Really into geology aren’t we.

How does that help ToE?

Are you claiming that inanimate geology is comparable to living organisms?

You are fishing. And hoping, And seeing what yo want to see.
They could be feather like plants.

You know the period the two creatures lived in. And?

You ae comparing two genetic patterns to each other an deciding what that must mean. It still does not demonstrate your hypothesis in real life.

If God created, thee results would be the same.

You are making wild assumptions based on similarities.

It does not prove that the diagram is correct.

It lived there.

etc, etc.

Thee is always an answer. You may not like, or approve, or agree, but there is always an answer. It boils down to view and assumption. You ore me. I can no more prove God did something than you can that he didn’t *Or een existed)

No I shouldn’t. Isn’t that what you claim?

The trouble is. you have not proven me wrong. . (because it is not about proof)

And you cannot se the ambiguity of this ridiculous comparison>

okay

Been there, looked, rejected. Repetition of failed argument.

It is a shame you cannot see your own dogma and narrow minded view.

Okay

Not if they have preserved melanins in the feathers or feather attachment points on the skeleton.

The computer doing the analyses is assuming that parsimony works. That’s it. I have written a program to run in PAUP 4.1 to analyze morphological features and output a tree, so I ought to know what the input assumptions of such programs are. All they do is “arrange these so that the with the ones most similarity to each other are closest to each other”; the different types are either using slightly different definitions of “similar” or are checking for different types of statistical support.

Under the logic being used here, none of geology, ecology, systematics, taphonomy, or astronomy; and very little organismal biology is scientific or usable. This appears to assume that observational scientific methods are less robust than experimental scientific methods.

Not in the least. You’re as bad as Adam – he sees “Darwinism” everywhere, you see “science” everywhere.

Pollsters come to valid conclusions about human behavior based on similarly minuscule percentages.
Of course the difference is that the pollsters work to get random sampling; the formation of fossils is not random.

And just which of those provides a basis for the physical/mechanical and chemical analysis of rocks?

This is sufficiently egregiously wrong I can’t resist weighing in.
It’s fallacious reasoning: you’re confusing an expectation (prediction) resulting from a theory with a foundation for that theory.

You two are talking past each other here – one is saying the equivalent of “Yes, nomads often have livestock” while the other is saying, “None have been seen that have pigs”. Or perhaps, one is arguing that we know that buildings get painted while the other is saying we can’t look at a given painted building and know who the painter was.

No, they’re predicting what should be found if the explanation of the evidence in possession is correct. Whether they “want to see” it or not is irrelevant; when a prediction is based on two sets of data that point to the likelihood of a third set, and that third set is later found, that counts in favor of the prior explanation.

Sounds like a response from an insurance investigator who doesn’t want the company to pay up.

You’re engaging in a fallacy. It’s one the John Lennox mentions regularly, what he calls the “motorcar fallacy” – the idea that because Henry Ford produced motorcars then there were no mechanics (the technology, not the people) involved, or as is more commonly done, that because we understand the theory of internal combustion engines then Henry Ford wasn’t real.
It’s a confusion of agent with instrument. “God” is as valid an explanation for evolution having happened as the theory claims as it is for the opposite, because God is the agent, not the instrument.

No more than is the case with cosmology.

And who programmed the computer? God perhaps?

No, no and thousand times no!

I am not including other scientific endeavours! Why can’t anyone see this? Is it really that outrageous?

Science has its place, but it is not God and it can be fallible, and it has limitations.

I am tired of being accused of negating or belittling science and scientists!

I am not even claiming that all of evolutionary theory is wrong!

Get over it.

Richard wants you to be playing checkers when the game is actually Deluxe Mastermind.

Huh? Tell that to a geologist!

That describes cosmology, geology, and more.

You make that claim frequently. I can’t decide if it’s just bigotry or if it’s projection.
When it’s a scientist, “What you want to see” is whatever ends up being seen.
