22 Jun, 12:16 PM: Dear Jerry -- Thanks for all yours [above] and for permission to post. I have been thinking about these issues and want to followup if you are still interested. In particular, I am curious to hear an example or two of the paradigm cases that you mention. Presumably these would show that the process would require a mind? The devil (for me at least) may be in the details.And, finally, could I interest you in this logical point -- The origin of a genetic program for a major evolutionary step is an assumed event with no good supporting evidence, only supposed necessity based, ultimately, only on the big bang. (So's the origin of life.) At this point the lack of evidence is noteworthy, because it has been sought so diligently. But if genetic programs don't ever have to originate, all the big problems for evolution can be solved (with HGT), and the process demonstrated with computer models. ...Any response will be welcome. Thanks. Best regards. Brig
25 Jun, 10:33 AM: There's no lack of cases that illustrate the adaptivity of evolution: exposure to antibiotics produces antibiotic-resistant bacteria; the color of moths evolves in the direction of the color of their background (likewise polar bears, etc.) Cf any standard introduction to evolutionary theory. None of this requires appeal to minds *until you ask yourself 'which trait is selected-for' in such cases?. Are white polar bears selected for being white? Or for matching their surround? Or both? Or neither?) What typically raises such questions is trait-linkage; anything that has either trait has the other. Arches and spandrels all over again ...Best, jf
26 Jun, 12:37 PM: Dear Jerry -- Many thanks for your patience. I have now re-read pp 98-100, where you say, "...nobody intended or planned for long-necked giraffes...." No, but there is a natural variance in features like size; couldn't natural selection act on that, and favor the ones with longer necks? (Longer everything it seems.) Why can't this happen? You say, "...it's best to aproach the exposition indirectly." But would you directly answer this question? Else, your logic is too subtle for me. People will think you are denying an obvious truth and dismiss you too hastily.
Please remember, I want to agree with you. And I suspect there is agreement somewhere to be found. For example, I do not think that natural selection for longer necks is limitless. Rather it is strictly limited to the range of the natural variance that exists originally. (If there is a bell-curve distribtion, natural selection can move the peak rightward to the tail of the original curve, but not beyond.) But if the giraffe's long neck is enabled by genetic programs that were not installed originally (before they had long necks), those "new" genetic programs cannot be accounted for by natural selection among giraffes. I think this gets you where you want to be anyway. Furthermore, it points to experiments and analyses that could prove fruitful. Thanks! Brig
27 Jun, 1:47 PM: I do think you're missing the point; but so does almost everybody else, so you shouldn't feel bad about it. You take for granted that that the trait that is SELECTED-FOR is having a long neck. What rules out the hypothesis that the trait selected-for is, as it might be, maximal distance between nose and tail? Or any other coextensive trait? In particular, what in the theory of natural selection rules it out? Likewise with any pair of traits that are 'linked' in that selection for either produces both. ...It's because the point is so obvious that everybody missed it for a century and a half. ...jf
5:42 PM: Again, many thanks. But I am now simply curious to know your opinion or belief -- ...Say the forage-trees are to high for all but the tallest pre-giraffes, who have a distribution of heights. In any given generation, only the tall-enough ones will survive, regardless of any other traits that may or may not be free-riding with height. And height is to a sufficient extent genetic (inherited). So, natural selection could cause the average height of the pre-giraffes to rise over several generations.
Do you agree????? ...If not, could I reword the premise, for example ...over several
generations the average height of pre-giraffes ...will increase because of a better survival rate??? ...I am seriously not sure where you are on this question. Your answer will help me understand where you're coming from. Forget about theories. Could the situation lead to the outcome? ...I apologize if this is tedious for you. (I am desperate for allies myself!) ...Brig
6:58 PM: But if the traits are linked, then selecting for maximum tail to nose distance will also get you long necks which allow you to forage in tree tops (and vice versa) . So again, the question arises, which (if either) was selected for? When the candidates are coextensive, Darwin doesn't say. In fact, nobody does. ..BTW, what on earth would you want allies for? ...jf
9:41 PM: Wanting not to seem rude -- I don 't care how you call it, tail to nose or whatever -- Could the situation described below lead to taller (plus or minus any other characteristics) pre-giraffes????? Are you able to answer? I don't *care* what the other dimensions are. I want to know if their mouthes can reach higher. I don't care if they are spotted or shiny. Could the situation make them taller? (Able to reach higher with their mouthes)? Please answer. ...I want allies because I think the standard theory of evolution is bullshit. So do you (think it's bullshit.) Let's see if we could find an alliance. Something major is wrong with Darwinism, but we opponents haven't said it well enough, yet, apparently. ...(Had 4 beers.)
28 Jun, 8:29 AM: I'm afraid one has to care which property is selected-for. Here's one reason: It's the consensus view that empirical theories should not only predict what does happen, but also what would have happened if.... (I won't go into why they should, but I doubt you'd find much disagreement among people who work in this area.) So now: consider the question whether what's selected-for is the length of the neck or the distance between the tail and the nose; and ask yourself what would have happened if the trees had been shorter: The first theory says the necks would have been shorter too; the second theory says it wouldn't have mattered. So, if you think that getting the counterfactuals right is important, then you should also think that getting it right about which property is selected-for is too. It's not an accident that people overlooked the problems about selection-for for more than a century. They are subtle and complex. ...BTW: there is some evidence that giraffes were not selected for long necks after all; it turns out they don't like to eat with their necks extended. ...jf
10:55 AM: The issue is still to subtle for me apparently. So I am muttering to myself, "I do not have to care." ...And I am also sorry that we anti-darwinists don't present a united front to the rest of the world! ...Thanks Jerry. May I append this recent exchange to the first one posted online? It may be helpful to someone.
29 Jun 10:31 AM: Dear Jerry -- I am still thinking about this. Your book was stimulating! If you get tired, it's OK to say so. ...Suppose there are two linked traits, but one of them is adaptive (helpful, beneficial, etc.) and the other is maladaptive (detrimental.) Then Natural Selction requires no mind whatsoever to selected-for the adaptive trait.
This is the case with resistance to malaria among some Africans. As you know, the trait is linked with increased susceptibility to sickle-cell anemia. ...Do you see anything in this argument?
12:28 PM: If the linkage goes in both directions, then you don't need to choose; if you select either, you get both. ...jf
What Darwin Got Wrong by Jerry Fodor and Massimo Piattelli-Palmarini is the related book review, posted 13 Jun 2010.
11:13 AM: Dear Mr. Klyce, I have been greatly moved and inspired by your work on Cosmic Ancestry. There are few times in life where I have the opportunity to be exposed to such insight. What I found astounding is the simple, readily graspable, and extemely powerful logic of your theses, particularly how comets can protect bacteria on their way to earth (the chorus to the song Woodstock started playing in my head) to propagate life.
If I was a master gardener with a limitless supply of land and seed, I would want to sow as far and wide as I could, makes perfect sense to me/ ...I have been lately deeply troubled with struggles of faith. I have read countless scientific articles back and forth on critiques of the odds of self-replicating DNA, and the hair splitting chemistry needed to demonstrate it one way or another. I thought earlier this week how absurd it is for me to hinge my belief in God on micro-biology, and as you have noted in your citation by Bertrand Russell and others, the depressing pointlessness of an existence all due to indifferent randomness. Your information is a total, wonderful, game changer.
Your work is a delight to read, and I am personally grateful for finding it.... Be Well, ...Jay Farquharson | Tonawanda, NY

Reply from Brig, 8:44 AM:
"...Every example that supporters of intelligent design produce to suggest that natural causes are not adequate—the bacterial flagellum, the blood-clotting cascade—has been shown to be the exquisite end result of evolution."
Stan, I have followed the bacterial flagellum question. The genes that code for the structure have identifiable predecessors that appear to be older than flagella (or their first appearance on Earth anyway). So the contention that "evolution" composed those programs is not supported by evidence.
...The Edge of Evolution... is a local book review with discussion of the bacterial flagellum, 18 Jun 2007.
"...Where, for example, is any discussion of the Grants' work on the Galápagos finches?..."
Changes in beak size and shape are examples of optimization, which computer programs can easily do. Speciation can result from randomness that causes incompatibility between genomes. Neither of these processes has been shown to be capable of composing new programs. In fact Ruse's whole list following this short quote is irrelevant to the question of where new genetic programs come from.
Thanks for the alert. I wish I had seen the review when it was new. Probably too late to chime in at The Chronicle now.
