Re: Introduction
If you don't understand my point, why don't you ask me to explain it
I addressed your point.
Go ahead and explain how you didn't mean what you plainly wrote.

Re: Introduction
No.
So that's two replies now you've avoided clarifying what you allege is a misunderstanding on my part. I guess you're bowing out of our discussion.

Re: The purpose of phylogenetics
Gaylord Simpson wasn't using molecular phylogeny, though, was he?
I think you're missing caffeine's point.
You guys are constantly stressing the supposed "consilience" of data, yet the history of evolution theory shows conflict, e.g. molecular data causing major revision of evolutionary relationships that had been inferred from fossil morphology.
And the fossil data alone had already produced all sorts of conflicting interpretations.... and no, not at the "tips of the branches", but among entire classes of animals like mammals.
The rosy picture that evolutionists paint for the public tends to be a world apart from the picture they discuss among themselves in the literature.

Re: The purpose of phylogenetics
So when taxonomy based almost entirely on form met DNA, errors were found and corrected. But molecular biology could have totally trashed the entire tree - it didn't, it confirmed it in spades.
What he's saying is that because DNA didn't group giraffes with turtles instead of other mammals, Common Ancestry was totally vindicated.
Evolutionists really set the bar high.

Re: The purpose of phylogenetics
And I gave examples of how this didn't agree with morphology when you, vaporwave, you said "DNA confirmed the pattern of shared physical features and functionalities of organisms." And then even after I had pointed out your mistake you continued to asset "There is a robust relationship between genetic information and the type of morphology that it organizes. I don't doubt that."
As I said, there is a pattern. Animals that share similar anatomical systems tend to share similar genetic organization of that anatomy.
Your problem is you cannot see the distinction between this observation and your assumption of common ancestry.

Re: The purpose of phylogenetics
I guess we'll have to wait and see what caffeine says he's saying, but I can't make any sense out of that sentence.
Sorry I was referring to you not caffeine.
Neither taxonomy, nor DNA groups turtles with mammals.
Right, and to an evolutionist this is vindication of the theory. Because if DNA had grouped one family of mammals closer to reptiles than other mammals, then Common Ancestry would have been falsified. Evolutionists use examples like this to celebrate how amazing the theory it is.
But without common descent there's no reason for DNA and form based taxonomy to agree on their classification
Oh good. I'd love to know how you've arrived at this special knowledge of how life would or would not appear absent of common descent.
Dr. Adequate vaguely alluded to calculating the chances of this scenario but he kinda clammed up when I pressed him for details.

Re: The purpose of phylogenetics
Right, you see when two different methods of organising groups into sets produce the same result, it strengthens the idea that the sets are correct
The "sets are correct" ? What does that mean?
Had molecular biology produced a different result, there would have been a lot of head scratching
Debatable. The common ancestry narrative is surprisingly malleable.
Also, I asked you to explain how you knew this:
But without common descent there's no reason for DNA and form based taxonomy to agree on their classification
It seems a lot of your case hinges on this claim.

Re: The purpose of phylogenetics
It doesn't explain the general concordance of various types of molecular phylogenies: protein sequence data, ERVs, phylogenies constructed from synonymous sites, etc.
Eh... I don't see that concordance as confirming much of anything but the concordance itself.
You seem to be making the same leap in logic and just assuming common ancestry.
You are selecting a group of shared traits (e.g. mammals: endothermy, hair, neocortex, mammary glands, etc.) and bringing them into deeper focus on a molecular level, and finding the pattern of similarity to persist.
Why would it not persist?

Re: The purpose of phylogenetics
It's not the similarity that matters here. It is the concordant nested hierarchies of similarities that exist between disparate sequence data.
What do you mean similarity doesn't matter? The nested hierarchies are arranged based off similarity to begin with.

Re: The purpose of science
Well grouping giraffes with turtles would have falsified that section of the morphology phylogenetic tree hypothesis, wouldn't it?
Probably, yea. I just think it's lame to consider it a stunning victory of evolution theory.
I think even if molecular researchers had no concept of common ancestry they could have made similar predictions based off the simple idea that beings of similar anatomical properties are going to be more similar to each other in additional ways than not.
If you had no concept of evolutionary relationships and furthermore knew absolutely nothing about internal anatomy and saw a dog, a cat, and a turtle. Which ones would you guess to be more similar to each other if you dissected them?

Re: The purpose of phylogenetics
It's the concordant nested hierarchy of similarities that matters because randomly distributed similarities would be rather contrary to the evolutionary synthesis.
I'm still not getting the distinction you're making. I thought that's what I was saying with the mammal example... that the similarities clearly are not random. We find similar anatomy tends to be organized by similar genes.
Can you give an example of what you're talking about....

Darn... Tangle, you were just teasing I see.
You refuse to back up this claim... just like Dr. Adequate...
But without common descent there's no reason for DNA and form based taxonomy to agree on their classification

Re: The purpose of science
Markers in non-coding sections of the DNA that could only be preserved by descent from an individual that first had the mutation, and no reason for it to occur other than random mutation.
Or maybe they are left-over from a previously served function.
If I dissected them and used the results to form an hypothetical relationship, I would not be guessing I would be comparing empirical objective data and using that as the basis for the hypothesis.
Why'd you dodge the question? You're telling me you couldn't make a guess before you dissected them?

Re: The purpose of phylogenetics
When you organize 30 different taxa by morphology and by cytochrome c you get a perfect match between them:
Do you get a perfect match with cytochrome b ?
There is absolutely no reason that a creator would be forced to match cytochrome c sequences to morphology.
Okay, what's your point? There's no reason evolution would be forced to give rise to eukaryotes.

Re: The purpose of science
Google Chrome on the PC and Mac look almost exactly the same from the outside, yet the machine code underneath is entirely different.
Was the code for each version written by different people?
Why wouldn't we think the same of different species? Why couldn't we see very different DNA even if their morphology is similar?
Why expect this? If a particular template works, why change it?
