In Why Evolution is True, Jerry Coyne writes that gradualism is one of the six tenets of “the modern theory of evolution” (which he equates with Darwinism – see page 3).
Eugene Koonin writes that the tenet of gradualism is known to be false (The Logic of Chance p. 398).
Yet gradualism is obviously still quite popular here in “The Skeptical Zone.”
Surely gradualism is not a logical requirement or entailment of the theory of evolution. Neither is it supported by the evidence.
So given what we know about evolution, why do evolutionists still cling to gradualism? My suspicion is that the alternative smacks too much of miracles. So gradualism is more of a religious conviction than a scientific one.
What is the evidence for and against the gradualist hypothesis?
Alan Fox,
Heh. It’s on the cusp of incomprehensibility and incontrovertibility at the mo! 😉
I’m pushing the idea that sex is completely explicable without the need for yet another theory – the mainstream says no! Not quite the stuff of revolutions. I think there was a time people thought there was a great prize in solving it, and you needed a theory succinct enough to get on the citation!
Not very impressive reading skills Allan, maybe take another shot at it.
Aardvaarks and South American Anteaters. The aardvark is the descendant of the salmon in this evolution tale. You are really struggling with something pretty easy.
If this is the best understanding you can manage, I think I see the problem.
I think the idea that there are more than one possible trees of nested hierarchies contradicts the idea of a tree of nested hierarchy.
This article by Casey Luskin is a good rundown of the problems with the nested hierarchy theory:
Just a snippet:
You have a link , should be pretty easy.
Sometimes, so not always?
But phoodoo, this “mosaic of traits” is exactly what we would expect under common descent by accidents coupled with conservation and/or loss due to random environmental changes. It’s the theory of anything is possible unless you can prove otherwise.
phoodoo,
Gah, that’s even worse. When you flail, you really give it a good go, I’ll credit you that.
Your original had salmon and anteater as having a common ancestor. Now you are proposing direct descent of anteater from salmon. In neither case have you even given an inkling that you know what is meant by evolutionary convergence.
No, you really don’t.
All the same old shit over and over and over again. You never learn.

Mung,
No it isn’t. It does pose an interesting scientific conundrum though, which research is endeavouring to solve, regarding the correct placement of comb jellies on the tree of life. It is entirely forced by the fact that you can’t just stick them anywhere. That is, the opposite of what you caricature.
How’s the study of ‘teleology’ coming along, meanwhile? The deeply illuminating theory that whatever we see is what the Designer wanted to happen?
The Designer has, indeed, taken great pains to ensure that traits don’t get ‘mixed up’, fooling generations of systematists into thinking the pattern represents a phylogeny. Why did he get it so wrong in the case of the comb jellies, one wonders?
It designed it on a Monday after a long weekend
Right, sometimes its still just as confusing afterwards.
Allan, did you hit your head with a paddle?
Not only have you completely failed to understand even the simplest of concepts, you now aren’t even capable of using complete sentences as a rebuttal. What are you even trying to say? Do you even know?
You don’t even have the faintest idea what you are saying, do you? Where in your screwed up mind did you come up with the notion that I said salmon and aardvarks (not anteaters fool, I even explained the difference) were examples of convergent evolution?
Anteaters and aardvarks Allan! Try reading. And pull the dam oar out of your skull.
No fucking kidding Allan? Its almost as if Mung was being facetious.
Did you contract some strange bacterial meningitis at the same time you whacked yourself paddling?
When Allan Miller isn’t here to set people straight it’s as if there is simply no alternative to gradualism. So I guess it’s good to have Allan back. 🙂
Now if he could spend some times explaining probability to Rumraket …
phoodoo, you might consider that Allan hasn’t quite recovered yet from his contact with Alan Fox. Now that he’s back in the company of reasonable folks like you and I he’ll come back into his right mind. Just you wait and see.
That is not what your quote says
Mung,
Look Mung, nobody, I mean NOBODY would advance this crazy reverse gambler’s fallacy that because something happens more than once its probability is even more likely.
No fool would advance that whacky strawman, not even Rumra…
Ok, look nevermind. I gotta get this canoe out of the water somehow, its not going to be easy with this wooden thing sticking out of my head.
I was curious about the last common ancestor of salmon and aardvark.
Well then just make up a story about it.
That’s what evolutionists always do. It always works.
And if you can make up a story, that means the story is at least plausible, and that teleology is false.
newton:
According to phoodoo, aardvarks are directly descended from salmon:
Dear God,
Where do you find these guys?
I mean, phoodoo, Mung, and colewd? These are the folks you’ve chosen to represent you here at TSZ?
When and why was cluelessness designed?
Glen Davidson
phoodoo,
My screwed up mind was confused largely by the confused portrait you sketched, under the illusion you were being amusing. But then further confused by your declaration that, in your thigh-slapping, eye-wipingly hil-arious caricature, one or other species (I can barely be arsed to find out which) was a direct descendant of the salmon.
I should, I realise, stay off the hard stuff.
phoodoo,
It’s almost as if I knew that, but chose to address the matter anyway.
Actually, re-reading, I concede to phoodoo that I got it wrong. He was not actually talking of the salmon and the anteater/aardvark being convergent at all.
This concession and apology were made far easier by the calm, reasoned and gentlemanly fashion in which phoodoo pointed this out to me. An example to us all, I think.
Designed traits are very good. Of course, I’m not saying so because God’s Word tells us so: “And God saw every thing that he had made, and, behold, it was very good” (Genesis 1:31). The empirical evidence strongly supports it. Plus it stands to reason. And Aristotle said so, too. Thus it can’t be a religious belief. Or not a distinctively Abrahamic religious belief, anyway.
Not very good traits are the result of evolutionary decay, because mutation only breaks stuff.
They don’t call them repair enzymes for no reason!
Nice to see keiths praying. He ought to consider praying for himself.
Dear God, why does no one like me when I am so perfect? Why didn’t you chose me to represent you? What’s wrong with you, God?
Mung,
You, phoodoo, and colewd illustrate perfectly why praying is a waste of time. (I’d be remiss not to mention fifthmonarchyman, too.)
Why doesn’t God ever help you guys out when you’re defending him? Aren’t you praying hard enough? Does he like atheists better than believers? Or does it have something to do with the fact that he doesn’t exist?
And if he does exist, he sure seems to enjoy watching his devotees fail, again and again. How do you explain this peculiar predilection of his?
I don’t ask for God to help when I am eating ice cream or jello either.
So your excuse for failure is that you don’t pray for God’s help, since witnessing is no more important to you than eating jello?
I thought you were whining about my failure to “defend God.” Have you given up on that line and decided to try another?
I think I get it. If it’s hard for keiths, it must be hard for everyone else too. It never occurred to him that he might be the one that needs help.
Can I get a witness!
Mung,
No, I’m laughing at your inability to defend him:
You fail repeatedly because the case for your faith is weak and you are inept at defending it. The fact that God never bails you out is just the icing on the cake. Your faith is a faith for suckers.
(I don’t blame your God for letting you dangle. It’s hard for him to intervene when he doesn’t exist.)
You’d think they’d notice that peculiar absence after a while.
Well in a way they do, but they’ve invested too much to recognize it for what it is. Thus apologetics is born in all of its dreariness, and ID provides the “miracles” that God somehow fails to perform today.
Glen Davidson
I am glad you noticed what a gentleman I was Allan, because originally I was going to say something really dickish, like:
But then I decided, no no, I should take the high road, like Allan, er, like some people would.
But I really am proud of you for recognizing a calm reasoned reply when you write, I mean see, one, Allan.
Gah!
Not only evolutionists, teleology is a story .A designer who creates something somehow is another.
Does punctuated equilibrium pose any challenge to gradualism? Some people would say no, but Gould says yes.
What is the ID position, either way is as likely or unlikely, there is really no way to know?
“Gradualism sometimes works well.”
– Stephen Jay Gould
heh
Some things never change.
Makes you wonder whether the evolutionists here have ever actually picked up and read a book on evolution.
Impossible. lol. Clearly.
Does actual evidence really matter in this debate?
I think Gould is very glad gradualism doesn’t always work, or most of us would never have heard of him. He is that famous slogan writer, right?
“Hmm, I need to come up with a name, to disguise another one of the problems with Darwinian evolution… Modern Synthesis? No, I don’t like the ring of that, save that one. Neutral Drift? Nah. I got it, PE, like PE class! What starts with P? Punctual Evolution? I like Punk music. I got it, Punk Equality! Mmmm, maybe too political, let me keep thinking.”
phoodoo,
You’d already decided to be an ass in your very first post to me, to which that was a response, so fuck off.
