There are on the order of 150 base mutations in every human.
As ever, Jesse
Uh oh, we are devolving.

Rate, molecular spectrum, and consequences of human mutation

Unfortunately, it has become increasingly clear that most of the mutation load is associated with mutations with very small effects distributed at unpredictable locations over the entire genome, rendering the prospects for long-term management of the human gene pool by genetic counseling highly unlikely for all but perhaps a few hundred key loci underlying debilitating monogenic genetic disorders (such as those focused on in the present study). Thus, the preceding observations paint a rather stark picture. At least in highly industrialized societies, the impact of deleterious mutations is accumulating on a time scale that is approximately the same as that for scenarios associated with global warming—perhaps not of great concern over a span of one or two generations, but with very considerable consequences on time scales of tens of generations. Without a reduction in the germline transmission of deleterious mutations, the mean phenotypes of the residents of industrialized nations are likely to be rather different in just two or three centuries, with significant incapacitation at the morphological, physiological, and neurobiological levels.
 
Hi Jesse,

Conceptually ID is not a search for things that cannot be explained. It’s a search for things that can be best explained by a particular kind of explanation (and, obviously, concomitantly the attempt to work out a robust theoretical framework to specify the nature this kind of explanation, to determine what conditions should be reasonably said to call for an inference to ID - rossum seems to get this, try reading his posts). Again, you clearly misunderstand the conceptual structure of the ID argument.

Dave
Hello Dave,

I actually know rossum from another board, and he’s an interesting fellow. He’s not saying anything different than I am. I’m drawing a distinction here between what ID is, and what it aspires to be, and speaking principally of the former. The kind of explanation that ID requires, but does not have, is a robust theoretical framework composed of enough information about its putative designer to infer, given a particular object, that that object was designed by that designer. Necessarily, the search for such objects is restricted to examples that have no natural explanation. As these are the only explanations that actually exist at present, the conceptual structure of ID, as it is actually practiced, encompasses no more than a search for objects without explanation.

As ever, Jesse
 
Hello again.

This is fairly embarrassing. As gently as possible, I recommend that you actually read the paper before trying to analyze it, and certainly before posting a link allowing others to do so in your stead. There is no suggestion of a contradiction with other researchers here.
We conclude that, since the separation of the chimpanzee and human lineages, sequence gain and loss have been far more concentrated in the MSY than in the balance of the genome. … In this respect, the MSY differs radically from the remainder of the genome, where < 2% of chimpanzee euchromatic sequence lacks a homologous, alignable counterpart in humans, and vice versa 15.(Reference 15 is the primary research I linked to earlier, by The Chimpanzee Sequencing and Analysis Consortium: Initial sequence of the chimpanzee genome and comparison with the human genome. Nature 437, 69–87 (2005).)

As the human Y-chromosome is composed of some 60 million of our 3165 million bases, or 1.9 percent, and the MSY region is only a fraction of this, I invite you, before boldly making claims that can be contradicted by arithmetic, to first do the math. The Y-chromosome, our smallest chromosome, principally a degenerate X-chromosome, is in a land of its own. The MSY does not represent the remaining 98 percent of the genome. By the paper you have yourself cited, it is instead “radically different.” As the MSY region retains about 70 percent similarity between chimps and humans, your “so much for 98 percent” is a reference to differences found in only 30 percent of 2 percent of our genome, or 0.6 percent.

As ever, Jesse
How much larger is the chimp genome than human?
 
Experimental evolution reveals resistance to change

Until now, experimental evolution has been largely performed in asexual systems with small genomes, such as bacteria and yeast. Burke et al. report results of a genome-wide study in Drosophila melanogaster fruitfly populations, which were selected in the lab for more than 600 generations to develop rapidly from egg to adult. In contrast to what is seen in asexual populations, the authors report ‘soft’ selective sweeps in which selection acts on pre-existing, common genetic variants, and conclude that unconditionally advantageous alleles rarely arise, are associated with small net fitness gains, or cannot fix because selection coefficients change over time.

Hi Jesse,
I’m pretty sure that the content of rossum’s posts has been quite a bit more sympathetic and more open-minded than yours. I still think you are mistaken about what ID requires, although I’m open to hearing an explanation of what is wrong with current ID theory (esp. Behe, since his book is the only one I’ve read).

You claim that ID requires information about its putative designer, but that’s really not the point. The point of ID insofar as it is a potentially scientific theory is about intelligent design itself, not the designer who is intelligent.

When you say that the search for examples of design is restricted to objects that have no natural explanation, that claim is tendentious. The result of ID has to be to expand the scope of what is considered to be a “natural explanation.” There is no a priori criterion by which what counts as a “natural explanation” must exclude the notion of intelligent design - is there? This at least calls for some explanation, doesn’t it?

science studies the real world. So far there is no real world evidence of any of id’s proposed designers. So far there is no evidence of where id’s proposed designers are supposed to have operated. So far there is no evidence of what abilities id’s proposed designers have. So far there is no evidence of when id’s proposed designers are supposed to have operated. So far there is no evidence, beyond conjecture, that id’s proposed designers have actually designed anything.

you claim that id requires information about its putative designer, but that’s really not the point. The point of id insofar as it is a potentially scientific theory is about intelligent design itself, not the designer who is intelligent.

This at least calls for some explanation, doesn’t it?
it also has the effect of rendering it impossible to conduct any experiment to disprove id. If the designers were aliens from planet zorg then we could disprove id by showing the existence of something that those aliens could not do. Since god is omnipotent, there is nothing he cannot do so it is impossible to disprove id if god, or any other omnipotent entity, is included.

All the discovery institute version of id can be is a strategy to get disguised creationism taught in us schools. It is a political and legal strategy to avoid laws on the separation of church and state. It is not, as currently constituted, science.

Rossum

Hello again, Dave,

I dunno. Maybe that does come off as more sympathetic than my position, but I can’t see any daylight between the substance of our posts. I was actually in the process of noting the lack of progress by Dembski since his 1998 monograph when I discovered rossum had beaten me to it. That wasn’t the first time on this thread, either. I suspect my pique at rossum repeatedly scooping me may be flavoring my language in opposition to ID. 😉

Let me stress instead that there are conceptions of ID I could support. It’s just that none of them are evident in the work of ID’s current proponents. In granny’s back porch thread, she leaves a link to a presentation of the Thomist opposition to the current movement. I read it carefully earlier today. The discussion was motivated by the exasperation of current ID proponents with the luke-warm reception they’ve received from Thomists, who one might suppose would be natural allies. Thomists, it seems, prefer their designer get it right the first time. More directly, they lend their support to a creator God who is the cause of the natural processes that brought about ontological existence, rather than a designer who acts as an agent of change. I can’t argue with that.

More succinctly, I have no real argument with those who claim evolution is their god’s ID.

Evolution is itself a design, and to whatever extent it could be said to have a creator, I have no objection to those who prefer to name that creator their god. This isn’t what ID proponents are saying, though. You’ve read Behe, though you don’t say which one of his books you’re speaking of, Darwin’s Black Box or The Edge of Evolution. I’ve read them both. What are these other than extended arguments for the existence of organic objects that biological evolution cannot produce?

Now I can contemplate a theory that would allow us to measure the design included in the creation of man-made objects. Perhaps it might be possible to measure the design of more pedestrian creatures in say, spiderwebs or beaver dams. I can’t imagine even beginning the attempt though without an understanding of the tools they bring to their creations. Beavers are fashioned to be highly efficient beaver dam creators. The design they bring to the project is minimal. A human might be able to create one, too, but it would be a much more design-intensive task. With that in mind, allow me to challenge you with a couple of questions in return. What if it was in your intelligent designer’s nature to create universes simply? What would be the measure of the design?

As ever, Jesse

I agree, and can’t argue with that, but it’s worth pointing out that your agreement (and mine) is just a nod to the idea that you can’t argue with a tautology. The trivially true is true.
More succinctly, I have no real argument with those who claim evolution is their god’s ID.
It doesn’t pit theists against the evidence when that happens, I’ll grant. That is something. It still trades on credulity, though.

Fair enough. Darwin’s Black Box was a fail, but Edge of Evolution at least presented the “right kind of wrong”, a claim that can be refuted scientifically, and in a substantial sense hadn’t been at the time of publishing. It’s an argument from incredulity – how can evolution produce new protein binding sites??? – but an interesting one for science to answer (which didn’t take long, cf Abbie Smith’s spanking of Behe on her ERV blog).
Now I can contemplate a theory that would allow us to measure the design included in the creation of man-made objects. Perhaps it might be possible to measure the design of more pedestrian creatures in say, spiderwebs or beaver dams.
Yes, and note for each of those how crucially dependent on knowledge of the capabilities and opportunities of those designers is to the inference. “Design detection ignorant of the design agent” is a non-starter. Design detection is the product of matching phenomena with agents and their abilities/actions. For ID-creationism, the agent is unknown/unnamed, and its abilities are just assumed to be whatever they need to be to account for any challenging phenomena. Vacuous.
I can’t imagine even beginning the attempt though without an understanding of the tools they bring to their creations. Beavers are fashioned to be highly efficient beaver dam creators. The design they bring to the project is minimal. A human might be able to create one, too, but it would be a much more design-intensive task. With that in mind, allow me to challenge you with a couple of questions in return. What if it was in your intelligent designer’s nature to create universes simply?

:banghead: :banghead: :banghead:

Why can’t anybody get it right? Creation Cause! Cause requires some exigency to start with. Creation does not. Hence the definition, “where something comes to be where there was nothing before.” There is no stuff required a priori in order to accomplish the creative action, as there must be for the causal action.

This was not necessarily meant for you, TS. You just happened to sneak in there before me.

I am English, so it may just be English understatement meeting an American expectation of overstatement. The Discovery Institute has no intention of taking its version of ID anywhere near to being science. At every turn where it has had to make a decision between doing the politically expedient thing and the scientifically correct thing it has chosen political expediency. One glaring example is its refusal to put any dates on anything so it can keep its ‘Big Tent’ open to the YECs who supply the money and footsoldiers it needs for its political ambitions. DI-ID was started by a lawyer and has as its main aim finding a way to get disguised creationism into American public school classrooms. I do not see that changing any time soon; the DI has always put politics before science.

Some individuals working in ID are trying to do science. Professor Behe has done useful work in this area and I sometimes cite his paper on the evolution of Irreducible Complexity, Behe and Snoke (2004). Both Robert Marks and ‘Mike Gene’ have also done some worthwhile work. However, much of the work touted by the DI is not good science at all. It is political propaganda but given enough of a veneer of ‘scienciness’ to appear to be science to non-scientists.
You claim that ID requires information about its putative designer, but that’s really not the point. The point of ID insofar as it is a potentially scientific theory is about intelligent design itself, not the designer who is intelligent.
A designer who cannot manipulate DNA cannot have designed any DNA. If you claim that a piece of DNA has been designed then it is up to you to show how, when and where that piece of DNA was assembled. An archaeologist can look at a potsherd and tell you where it was made, when it was made and who made it. Science expects ID to work towards a similar level of detail. That requires some knowledge of the proposed designers: where they lived, when they lived and what they could or couldn’t do.
When you say that the search for examples of design is restricted to objects that have no natural explanation, that claim is tendentious. The result of ID has to be to expand the scope of what is considered to be a “natural explanation.” There is no a priori criterion by which what counts as a “natural explanation” must exclude the notion of intelligent design - is there? This at least calls for some explanation, doesn’t it?
A natural explanation of design requires a natural designer. A supernatural explanation of design can include a supernatural designer. If we find natural evidence of intelligent aliens then we can expect to find intelligent designs by those aliens. Despite looking, science has so far found no evidence of any supernatural entities nor of any supernatural design.

How would you propose to go about showing that the design you claim to find in biological organisms on Earth is due to supernatural designers as opposed to visiting aliens from planet Zorg?

That is why IDvolution is the solution. St Thomas would be happy with it.

Wow!

You have just opened up a new avenue of thought for me.

Is this leaning toward a “god-of-the-gaps” theory? From what I understand about ID, it is not proposing a “god-of-the-gaps” position, but rather using instances of irreducible complexity as evidence of overall intelligent design. In my humble opinion, the only living organism which biological evolution cannot completely produce is the human person whose nature is rational/corporeal, material/non-material.

It is my intention to respect the current ban Sticky: Temporary Ban on Evolution/Atheism Threads

Sorry, Rossum, but my brain is being taxed by all these deep thinking posts and my sense of humor (such as it is) kicked in. Your question is valid.
 
(which didn’t take long, cf Abbie Smith’s spanking of Behe on her ERV blog).
Hiya, TS.

Double-down on the recommendation here. Yeah, she’s delightful. I’ve been following her contributions since the Internet Infidels days.
My purpose in replying was really just to pass along a link you (and others) may find interesting on the Thomist/ID argument from Uncommon Descent:

Here we part ways. I cannot recommend UD. Dembski’s blog is beyond annoying.

I can’t throw a rock without hitting a fellow former Infidel who’s been banned from there. They don’t allow disagreement, no matter how thoughtfully or politely posed. Lizzie Liddle’s experience was especially cautionary. Unsatisfied with merely banning her, Dave felt it necessary to lash out at her muted remains in a continuation. What’s linked here isn’t the original continuation, either, as another of UD’s common foils is to simply replace or disappear any post or portion that proves too personally embarrassing. (The original links painting her as a radical due to her participation in a radical board … from which she was banned for dissent … reached a level of irony that not even Dave could miss.)

There’s no point in reading Torley’s broadside critically, as there’s no forum open to discussion of its lapses. Which is just as well, as his response betrays all the signs of having been put together hurriedly. It’s disorganized to the point of unreadability, with the train of thought wandering aimlessly between his two, separate drafts. I suspect Torley has confused his own personal pique with persuasive prose. His smoking guns visibly misrepresent Tkacz, leading me to suspect he’s likely to have done the same with Aquinas, though I’d have to rely on an Aquinas scholar to verify this. We do, of course, have reason to expect this, as he is, after all, directing his accusations of Thomist heterodoxy at a Thomist, while freely and admirably admitting his own lack of preparation to do so.

At the same time, I appreciate his attempt, if for no other reason than to introduce me to the flaws in Aquinas occasioned by the poor scientific environment of his time. It strikes me as inappropriate at best, however, to use those flaws as a measure of modern day Thomism. I’m nearly certain that Tkacz and his fellows have long since come to terms with scientific demonstrations that flies do not generate spontaneously from dungheaps.

As ever, Jesse
 
Here we part ways. I cannot recommend UD. Dembski’s blog is beyond annoying.
Well, one of the few good things I can say about UD is that Dembski is never there anymore. UD, though, is an accidental host to many of the moust thought debates on ID to be found anywhere on the internet. As someone banned from there long ago (my entry is in there in the Bannination thread on After the Bar Closes), I’m well aware of the cowardice and caprice that rules UD editorial policy, but they regularly have enough guilt pangs to allow thoughtful critics to engage for a while before they lapse back into victory-by-censorship mode (and this is particularly disgusting at UD, where they don’t even have the decency to note for the record that a commenter has been banned, and just let his opponents carry on as if the banned person has fled in realization of their defeat).

If you go read threads where “Diffaxial”, “Nakashima”, “R0b”, “markf” and others (typically posters who hang out at After the Bar Closes) participate, many of them are tours de force in the deconstruction of ID in its various forms, not to mention solid positive defenses of mainstream science and scientific epistemology (and assorted philosophical issues, like Diffaxial’s discussion of compatibilism).

It’s an intellectual cesspool on the editorial side, and many of the posters (cf. bornagain777, kairosfocus, etc. are self-caricaturing creationists), but UD I see as a rare (if toxic) foil for some really brilliant work in clearly and thoroughly demonstrating the sophistry of ID, as well as showing how dispciplined reasoning and evidence-based thinking work in practice.

Those great posters eventually get banned. Even Nakashima, who was agonizingly polite and deferential (to the point of making me gag at points, to suck up to the like of Clive and crew), eventually was just too much horsepower for the management to tolerate.

But it was quality stuff while they let him cut them to ribbons with his mind.

Yes, agree, and am part of the banninated in the story, and have been a regular reader for many years, a “student of tard” like many others at AtBC. Uncommon Descent is “meta-instructive”, though; it’s useful to see how UD management and the pro-ID cabal proceed in terms of ethics, fairness, intellectual honesty, tolerance, and more than anything, focus on the merits of the science (“All science so far!”).

There’s no way to condemn the ID movement more strongly than to point an investigator at that blog and have them read it. UD really is useful (unwittingly) that way.

I should also say that while I disagree with so much of what is proposed here, CAF deserves recognition for its principles in tolerance and freedom of expression (within the bounds of civility) here. It speaks to the integrity and strength of the management and membership here that they don’t behave as the UD guys do.
There’s no point in reading Torley’s broadside critically, as there’s no forum open to discussion of its lapses.
A good point, I agree, and a point of frustration for me, too. vjtorley is deeply confused, and it’s too bad he is impossible to engage that way. But nevertheless, whatever vjtorley’s errors are, they are thoughtful errors, something wholly apart from the knuckle-dragging simple-mindedness of Clive Hayden or Barry Arrington or Gil Dodgen (never mind even bothering with O’Leary!).
Which is just as well, as his response betrays all the signs of having been put together hurriedly. It’s disorganized to the point of unreadability, with the train of thought wandering aimlessly between his two, separate drafts. I suspect Torley has confused his own personal pique with persuasive prose.

OK, you nailed me. I haven’t read but just the first page of the part one summary! Sorry, you may wellbe right. Having read (in frustration) many of vjtorley’s past treatises, though, critiquing them does take some work. He’s a fideistic fundy at the core, but it’s buried deep in a lot of careful argument that obscures that.
At the same time, I appreciate his attempt, if for no other reason than to introduce me to the flaws in Aquinas occasioned by the poor scientific environment of his time.

Just to be fair:

Civility of Darwinists Lacking at Academic Freedom on Evolution Event in Oklahoma

Science, E. coli, and the Edge of Evolution: Part 2

Response to Ian Musgrave’s “Open Letter to Dr. Michael Behe,” Part 3
 
Just to be fair:
Thank you, buffalo. I think this presents an agreeable opportunity to comment on fairness.
It should be understood here that an event staged by the DI devoted to critiquing lack of academic freedom in evolution is bound to arouse the pique of those who’ve been subjected to the DI’s Dembski’s restraint of academic freedom of those on his blog. As Luskin had specifically targeted Abbie in his talk for censoring a known troll on her blog, choosing to read his personal lack of familiarity with the case invidiously, the suggestion that judgment of Abbie’s expulsion from UD should be withheld due to his lack of personal familiarity with the case … didn’t go over very well.

There are times when flipping the bird is an appropriate response. An occasional encounter with flagrant hypocrisy is one of those times.
This being Behe, who never allows responses to his posts on UD, the juxtaposition with Luskin’s hypocritical tale of censorship is especially emblematic of DI’s contribution to the ID movement.

Agreed. The contrast between CAF and UD is both striking and instructive. “Preach always, use words if you have to,” is something that UD does not appear to understand.

Experimental evolution reveals resistance to change

Until now, experimental evolution has been largely performed in asexual systems with small genomes, such as bacteria and yeast. Burke et al. report results of a genome-wide study in Drosophila melanogaster fruitfly populations, which were selected in the lab for more than 600 generations to develop rapidly from egg to adult. In contrast to what is seen in asexual populations, the authors report ‘soft’ selective sweeps in which selection acts on pre-existing, common genetic variants, and conclude that unconditionally advantageous alleles rarely arise, are associated with small net fitness gains, or cannot fix because selection coefficients change over time.
Darwinian theory falsified, yet again. That paper is the conclusion to a 30 year study of fruit fly evolution. Researchers conclude that unconditionally advantageous alleles are not fixed in a population, and the ‘classic sweep’ of selection for a trait does not occur.
The researchers even enhanced the experiment by artificially selecting for optimum results. Lab conditions also provide a constant environment. The scientists observe that in the wild, results will show even fewer advantageous mutations evolving the population.

From the paper:

Despite decades of sustained selection in relatively small, sexually reproducing laboratory populations, selection did not lead to the fixation of newly arising unconditionally advantageous alleles. This is notable because in wild populations we expect the strength of natural selection to be less intense and the environment unlikely to remain constant for,600 generations. Consequently, the probability of fixation in wild populations should be even lower than its likelihood in these experiments. This suggests that selection does not readily expunge genetic variation in sexual populations, a finding which in turn should motivate efforts to discover why this is seemingly the case

We conclude that, at least for life history characters such as development time, unconditionally advantageous alleles rarely arise, are associated with small net fitness gains or cannot fix because selection coefficients change over time.
