One of the great things about UD is the insights that often come up in the comment boxes, by design and inadvertently. And here (at 147 in the Chemist speaks out thread) we have ecs2 responding to the same “he said it” clip I highlighted yesterday. He then continues later in the thread, in response to NM at 150.

Let us watch:

_________________

NM: >>“Sigh. You really have no idea at all about this stuff, do you?

Here’s the issue. Picture, in your head, all 5000 mammal species currently living on the planet. Now think of how many individuals are in each species — some are almost extinct, some have populations of billions. Now think about how each of these individuals lives and reproduces and dies over the years. Now add in how all of these individuals compete with each other, each each other, etc. Continue this process for millions of years, with species splitting and going extinct, sometimes randomly, sometimes due to climate change, sometimes due to invasions of other species, etc. Add in continents moving around on the globe, ice sheets advancing and retreating, and tens of thousands of other species of vertebrates plus hundreds of thousands of plant species and millions of insect species.

Then imagine what this process would look like if all you had was a very incomplete sample with lots of biases, in the form of fossils, most of which are fragmentary.

Suppose you are interested in doing science, and you want to develop hypotheses about the patterns you observe, and developed the data and statistical methods to rigorously test those hypotheses.

Now you’re getting some vague sense of what macroevolutionary studies are really about, why it requires actual training and work to be able to avoid talking nonsense about the topic, and why you can’t just read a popular book or two and blithely assume you know what you are talking about.”>>

ecs2: >>I don’t dispute your science. Not because I accept it, nor because I deny it, but because I am a learner in this area and don’t feel I have sufficient knowledge to discuss intelligently.

But I do have some comments on the quote above. It seems that what you are saying is that this is difficult. That there is not as much evidence as one would like, that you are have piecing together the theory based on fragments of insight.

This is understandable. It would be expected there will be error in this process. There will be surprises where theory must be revised. That the scientists involved should be very conservative in their judgments and conclusions.

The problem is this is the opposite of the approach I see. I see claims that evolution is true, that the evidence is “overwhelming” and similar words from that section of the thesaurus. I see grandiose narratives, speculative interpolation, and so on.

This is not science as I was taught it. This is not the scientific process I was taught. Good science doesn’t blackball alternative or minority theories or opinions. Good science doesn’t defend, protect, or promote a favored theory. Good science doesn’t discount the opinion of scientists from other fields who note where a general theory isn’t supported by theory within their field. Good science let’s the evidence speak for science rather than scientists.

But, in the end, the approach I see in evolutionary biology (some of which you have demonstrated in this thread) is damaging, most of all to theory of evolution itself.

Abuses of the scientific process contribute to increased skepticism – it raises the guard of those who are not informed and see only the human behaviors surrounding the science. And the truth is those behaviors don’t influence whether the science is ‘true’ or not.

I am still open to the theory of evolution. I still want to learn more and follow the evidence where it leads. But I admit that I am particularly cautious as I research it because of the approach of evolutionists in championing their theory.>>

[–> NM replies at 150, which ecs2 then excerpts. It should be noted that (as far as I have seen in following the exchanges) there has been no accusation of general fraud — what “bogus” means — in the field of evolutionary biology, though there have been concerns over bias, error and the inherent limitations of science especially where the objects of research, cannot be directly observed. Also, of course, there have been noteworthy hoaxes and frauds, such as Piltdown and apparently the Feathered Dinosaurs of the late 1990’s.  In addition, there have been serious errors such as not only the Nebraska man of the 1920’s “reconstructed” from the tooth of a pig, but also the suggested early whale of the 1990’s that turned out to be nothing like the early reconstructions. Also, there have been notorious debates and contentions such as over KNM-ER 1470 and related dating of isochron radioactive samples. Here, the fundamental challenge is that we face the deep and unobservable past of origins, and may only examine traces from that past that is forever gone from our direct reach. Thus, we make models and explain on patterns of cause and effect that we may observe in the present that give rise to similar effects to the items we find as traces from the past.  NM’s declaration that we are dismissing his field as “bogus” was corrected already, but unfortunately, it appears again.  This therefore seems to be a polarising and generally unfair misrepresentation of the questions and challenges being raised, one maintained in the teeth of headlined correction, and it should cease. There are also several other serious distortions that call for editorial notes like this, following.]

NM, 150: >> http://www.ucmp.berkeley.edu/s…..ations.php

I don’t dispute your science. Not because I accept it, nor because I deny it, but because I am a learner in this area and don’t feel I have sufficient knowledge to discuss intelligently.

But I do have some comments on the quote above. It seems that what you are saying is that this is difficult. That there is not as much evidence as one would like, that you are have piecing together the theory based on fragments of insight.

The problem is this is the opposite of the approach I see. I see claims that evolution is true, that the evidence is “overwhelming” and similar words from that section of the thesaurus. I see grandiose narratives, speculative interpolation, and so on.

The evidence of some big pattern — e.g. common ancestry — can be overwhelming, without every last detail being known. The evidence for plate tectonics is overwhelming, yet we don’t know the position of every grain of sand at every point in time, or even the exact position of every fragment of every tectonic plate at every point in time.

Science is about making good approximations, not omniscience.

This is not science as I was taught it. This is not the scientific process I was taught.

A lot of people were taught an oversimplified and basically fake version of “The Scientific Method”, which was based on the assumption that all science is based on lab experiments and that it follows a black-and-white step-by-step process. The actual process is more like this:

A simple summary of Science, as highlighted by NM as inadequate

Good science doesn’t blackball alternative or minority theories or opinions. Good science doesn’t defend, protect, or promote a favored theory.

So, you’re in favor of giving equal time in chemistry classes to the idea that Atomic Theory is false. Right? Oh, and homeopathy. [–> with all due respect, this is a strawman caricature of ecs2’s remarks]

Good science doesn’t discount the opinion of scientists from other fields who note where a general theory isn’t supported by theory within their field. Good science let’s the evidence speak for science rather than scientists.

I’ve been the only one citing actual evidence in these macroevolution threads.  All the UD regulars are just throwing up objections based on their personal lack of understanding of these topics,

[–> A strawman caricature, hasty generalisation and dismissal of serious and well-known objections, some of which are in fact citing evidence, others of which are addressing interpretation issues regarding well known evidence such as the pattern of sudden appearances, stasis and disappearance in the fossil record and cases such as the Cambrian fossils.]

and then pretending that they represent huge crucial gaps in the entire field.

You guys are the ones afraid to follow the evidence wherever it leads. If you were actually brave enough to do so, you would admit that transitional fossils are common, that common ancestry is overwhelmingly supported, etc.

[–> In fact, as NM knows or should know, design theory is neutral on the question of common descent, as can be seen from the view of Michael Behe, one of the two leading design theorists, who accepts common descent; as do many supporters of Design thought here at UD. What it is raising, is the question as to whether, via Common Descent, front loading or otherwise, there are signs in the world of life and in the cosmos more broadly that point — on empirical testing — to design as a key causal feature of our world. That is, we must distinguish (a) limited common descent, (b) universal common descent and (c) blind watchmaker thesis universal common descent; if we are to be fair to the various view out there. E.g. even, many modern Young Earth Creationists hold that “species” is an ambiguous concept and speak of “created kinds” or “baramins,”  which go up to the level of a Family or the like in typical taxonomical categories and would see common descent as active through variation and adaptation within the kind. Moreover, what I have just summarised is immediately accessible and directly observable, even well known here and now in the present. NM, if you — with your background of having been a public relations person for the NCSE (a leading Darwinism advocacy group), cannot be trusted to accurately and fairly summarise what we can all directly see here and now, how can we trust you to be objective and fair on traces and interpretations on  events that may lie 500+ to 3,500+ MYA? And, does this not constitute “fear of facing evidence,” easily accessible evidence?]

But, in the end, the approach I see in evolutionary biology (some of which you have demonstrated in this thread) is damaging, most of all to theory of evolution itself.

Abuses of the scientific process contribute to increased skepticism – it raises the guard of those who are not informed and see only the human behaviors surrounding the science. And the truth is those behaviors don’t influence whether the science is ‘true’ or not.

I am still open to the theory of evolution. I still want to learn more and follow the evidence where it leads. But I admit that I am particularly cautious as I research it because of the approach of evolutionists in championing their theory.

I try to be patient. But I’m human. When people who don’t know what they are talking about start declaring my field bogus, and then start blaming it for Nazis etc., I get annoyed. Anyone would be.

[–> As noted, this is a strawman caricature of objections. In addition, no-one has been

Logo, 2nd Int’l Congress, Eugenics Movement, 1921, showing claimed scientific roots [HT: Wiki]

raising the issue of the ethical challenges of materialism and of scientific racism that was deeply connected to Darwinism in Germany and elsewhere that did contribute beyond reasonable dispute to the rise of eugenics and did historically contribute to the genocides carried out by Nazi Germany. A responsible view of the ethical responsibilities of science in society, would frankly address such troubling issues from history. And, without trying to use this as an atmosphere-poisoning distractor, as this comment by NM plainly opens up.]

My advice for you is to keep reading, and start testing the creationist/antievolution claims for yourself.

[–> NM/NCSE know or should know, that design theory is not equivalent to creationism, or to antievolutionism. However, this rhetorically convenient conflation has consistently been used, despite repeated correction.  In addition, serious concerns on the limitations of evolutionary materialistic, blind watchmaker thesis narratives of the past of origins, are too often brushed aside as ” creationism” or the like.]

Is it really true that there are no transitional fossils? Start there and then start reading. It won’t be long.

[–> This ducks the issues just above, and fails to address the vexed question of the dominance of the fossil record at its various levels, of suddenness of appearance, stasis and disappearance. If the fundamentally gradualist, incrementally emergent tree of life model were true, from the root up, and if this were overwhelmingly evident to the point that we are justified in teaching High School students and the general public that this is a “fact,” the overwhelming majority of the fossil record should be of the many, many transitional forms — samples do strongly tend to reflect the bulk of a distribution, however crudely; and, arguably, many such should be quite evident in the world today. In addition, there is a basic challenge that from the root on up, the Darwinist three of life needs to be a tub that stands on its own bottom. That is, we need to see good warrant for the blind watchmaker thesis narrative on origin of life. We need to see good evidence on the pattern of chance variation and differential reproductive success in ecological zones, leading tot he descent with unlimited modification that accounts for the various tree of life models [I here advert to the inconsistencies between traditional trees and the various molecular ones]. It also needs to credibly account for the origin of human language and mind as a knowing, reasoning, perceiving entity required for such a theory to exist and have credibility.  NM knows or should know that the 6,000 word UD Darwinism essay challenge of Sept 23 on, is still standing, coming on five months without a serious response, though at least one has been promised. ]>>

ecs, 173: >>N.Matzke @150

“The evidence of some big pattern — e.g. common ancestry — can be overwhelming, without every last detail being known…Science is about making good approximations, not omniscience.”

This really evades my point, which was that you can’t do these things together:

1) in one aspect, articulate how difficult and explorative the process of building evolutionary theory is

2) in a separate aspect, act like these delicate and hard-to-build-and-interpet theories are bulletproof articulate how sound the theory is and how ‘overwhelming’ the evidence is

3) in a third aspect, act like the theories are beyond reproof, flippantly and rudely rebuffing eminent scientists who have questions.

One who tries to express these three things at once looks silly.

– If #1 then not #2. That is, if there is less evidence is desired and there are holes where interpolation is required, then the theory can’t possibly establish the confidence to state #2.

– If #2 then not #3. That is, if the evidence is overwhelming and the theory is sound, then you are happy to discuss it with other scientists whose fields overlap and you would expect your theory to hold up to those inquiries.

And so on. >>

ecs2, 174: >>

“A lot of people were taught an oversimplified and basically fake version of “The Scientific Method” …”

[–> In context, this is dismissing ecs2’s views on the methods of science as ill-informed; cf. a 101 here on this at IOSE, especially the expanded description of scientific methods; also here on on the debate in Kansas on scientific methods as taught in schools, in which NM’s former institution, NCSE, played a significant part. Bottomline: the “method” traditionally commonly taught in schools is somewhat simplistic, but it does capture some major and characteristic features of scientific investigation. In addition those trained in pure and applied sciences to graduate level are inculcated in a tradition of research that goes beyond what any description or definition can summarise — experience based expertise.]

This one actually annoyed me a little. I have a PhD in Engineering. I feel sufficiently familiar with the scientific process. You seem to make poor assumptions about those you read – because one has simple or rudimentary knowledge in your area of expertise does not make them simple overall or in other focused areas.

Two observations based on the link to ‘the real process of science’ which jumps off the page you linked.

1) There is no room on that graphic for the behaviors I mentioned. Of course science can be interpolative and exploratory. But the interpolation and exploration should still be dictated by the data. When I say grandiose narratives and speculative interpolation, I am saying that in my view some of what I have seen from the evolution community (not you specifically) violates the boundary condition of following rather than leading the data.

2)I noted in the exploration and discovery phase, the process you provided call the scientist to ‘ask questions’ (and presumably by extension to graciously receieve questions also) and also to share data and ideas (like across disciplinary boundaries (such as, I don’t know, organic chemistry and evolutionary biology). I think I have the process down. Do you (look back over this thread before you answer)?>>

When an egg of a female Monarch butterfly is fertilized by the sperm of a male, that cell, and its many daughter cells, set out on a long, targeted pathway: A to B to C—and so on, to Z, where Z is the adult form capable of reproduction, thus starting the whole cycle again. The pathway aims at the target of reproductive capability.

The evolutionary secenario doesn’t claim there was ever a caterpillar-like creature that added a butterfly-like stage to its life (a really bizarre idea if you know much about insects, actually).
Rather, it claims that there was creature that included both a caterpillar-like stage and a butterfly-like stage at the outset? And how did this system come about?Eric Anderson

Joe: it most definitely is possible to produce tests that FSCO/I and IC can and have been produced by blind watchmaker, Mt Improbable incrementalist mechanisms, or by wider blinde chance and necessity mechanisms. Remember, a reasonable threshold is 500 bits of functionally specific info, about 250 base pairs of D/RNA worth of storage. What I think is the real challenge is that to date, the only empirically credible, observed source of such, is design. So, Evo mat advocates, unlike design theorists, are not in a position to argue "like causes like." Indeed, a lot of the objecting rhetoric I have seen is designed to distract from or dismiss that very cogent appeal. And, ironically, if they were to succeed, all they would then be able to show is that such features can be produced by BOTH blind mechanisms and design. So, this cannot be where the decision would be made. And that is a best case they have not been able to deliver on, with the earliest challenge being Cicero's c. 50 BC. That's a mighty long time to be drilling away obsessively at a dry hole! KFkairosfocus

WD: I am sorry but that is beyond the pale. There is an issue to be addressed, of the origin of FSCO/I, in the context of an irreducibly complex system. THAT ISSUE IS NOT "RUBBISH." To dismiss it in such terms, rather tells me that you have no answer and are simply spewing an ideologically driven dismissal. Of course, if we assume a priori materialism, or if we accept that however life originated must be compatible with the trumpeted claims of that school of thought, then there MUST be some sort of Blind chance + necessity, incrementalist mechanism, regardless of evidence. And in that context, the slightest hint will carry the day. But, sorry, you are not in that ideological cocoon here. We have a reasonable right to evidence that warrants the claims being advanced. Perhaps, you are unaware that Gauger actually was orally assessed by James Truman, who seems to be a key proposer of the Juvenile Hormone model. In her oral viva in the 1980's, he asked her about "how I might account for the evolution of complete metamorphosis in insects." She had no answer, and asked him afterwards. Many theories, no decisive evidence. In 1999, with Lynn Riddiford, he proposed the Juvenile Hormone, concentrated change theory you alluded to above. This is what the authors I have been citing go on to say regarding that model: ______________ >> In this scenario, the development of adult structures, that appear gradually during the nymphal stages of a Hemi species, is “telescoped” into the pupal stage—giving rise to true holometabo-lous metamorphosis . . . . Juvenile hormone (JH) in particular maintains the status quo in holometabolous insects. In broad out-line, the story is that if JH is constant, the larva molts to another larval stage. When JH is withdrawn in the presence of other hormones, the larva moves to the next stage of development . . . . In Hemi species, the pronymph (PN, the first stage of [a]) is a non-feeding stage. Thus, if the development of the pronymph is going to be prolonged, to allow it to become a larva, it must si-multaneously evolve the ability to feed. “The ability of this stage [PN] to feed would seem to be an essential pread-aptation for it to evolve into the larva.” 14 . . . . this evolutionary story requires a new kind of pronymph, one capable of feeding. Otherwise, remaining a pronymph is a death sentence, not an advantage.Thus requirement 15, evidence of relevant variation, has not been met. A second, related problem is that if you expose a hemimetabolous embryo to high JH, you don’t get holometabo-lous development, you get a mess.15 Such embryos develop inappropriate nymphal rather than pronymphal char-acters and/or terminate development prematurely, depending on the tim-ing of the hormone application. This is because these hormones act by regu-lating a complex network of particular downstream genes. As a result, mess-ing with the timing or level of expres-sion of a hormone is in general detri-mental or lethal, not transformative . . . . But the biggest problems come because delaying development in the caterpillar requires that all of adult development be compressed into a single pupal stage. This is the point of transition between steps (d) and (e). In Holo species, there is considerable dis-solution of cells and tissues during the pupal stage and adult structures are constructed during this phase. For this to work, there must be some way to set aside cells that will build the adult tissues (wings, eyes, antennae, etc.) and to trigger their development into the right structures at the appropriate time. How this is done varies among different types of tissues. For example, some caterpillars reuse leg epidermal cells to contribute to the development of adult legs; this means that these cells must be able to produce two different kinds of cuticle. But caterpillars also use cells (called imaginal primordia or disks) that were set aside in the embryo just for mak-ing adult structures; these cells may remain quiet in the caterpillar and only begin to grow and produce adult struc-tures in the final larval stage and in the pupa. How do cells acquire the ability to carry out two different, sequential programs in response to hormonal signals? How do cells get set aside for future use? And how do you coordinate the two sets of cells to make fully functional adult structures? The flip side of the pupal riddle is that there also must be a way to specify and coordinate which larval cells will self-destruct. Programmed cell death is com-mon enough in development as a way of remodeling tissues into their final form (how natural selection can produce a process like programmed cell death is another question), but only in metamorphosis is pro-grammed cell death so wide-spread and catastrophic. Insects with hemimetabolous development change gradually with each molt and so do not require ex-tensive remodeling, but insects with holometabolous development remake themselves in one compressed stage. In response to the hormonal cues that trigger pupation, the majority of caterpillar cells initiate a cel- lular program that leads to their destruction—essen-tially, they commit suicide in order to make room for the new adult structures. >> ______________ Those are not trivial concerns, they describe a major, step by step process, that is tightly co-ordinated with specific differentiation that has to be co-ordinated: cell types X, Y,Z . . . must die and disintegrate, but P, Q, R must be preserved in the soup to make the new body structures and organisation of the adult form. All at once, and right the first time. So, I repeat:
That is what needs to be cogently explained, explained on Blind Watchmaker Mt Improbable incrementalism, backed up by adequate observational evidence. TWO body plans, only one of which is reproductive, and to be bridged by a process that reeks of astonishing irreducible complexity and massive functionally specific complex organisation and information involving not a prebiotic soup, but indeed a molecular soup. The Blind Watchmaker, Mt Improbable explanation for such is _____________ . It is backed by the following observed evidence that answers to the above issues ____________ . And, on the assumption that the evidence of the Cambrian fossils speaks to similar cases, the similar explanation of how we move to such from the universal common ancestor is _______, and this is backed up by actual observational evidence such as ________ that indicates ____________ . Could you kindly fill in these blanks for us?
And, on the notion that the slightly detrimental gives rise to advances, could you kindly inform us on how such is fixed in populations via differential -- advantageous -- reproductive success; and how it gives rise to the scale of body plan transformation to say create a whale out of a cow-like animal or the like, with relevant observational evidence that addresses this issue?

wd400 you make this 'wager'
I’d happily wager much complexity arises from slightly detrimental mutation(s).
And you would sadly lose whatever you wagered! Which is, IMHO, far more than you think it is!
Pascal's Wager - The Unavoidable Bet Everyone Makes In Life - video http://www.metacafe.com/watch/4224424 The Argument from Pascal's Wager Excerpt: Most philosophers think Pascal's Wager is the weakest of all arguments for believing in the existence of God. Pascal thought it was the strongest. After finishing the argument in his Pensées, he wrote, "This is conclusive, and if men are capable of any truth, this is it." That is the only time Pascal ever wrote a sentence like that, for he was one of the most skeptical philosophers who ever wrote. Suppose someone terribly precious to you lay dying, and the doctor offered to try a new "miracle drug" that he could not guarantee but that seemed to have a 50-50 chance of saving your beloved friend's life. Would it be reasonable to try it, even if it cost a little money? And suppose it were free—wouldn't it be utterly reasonable to try it and unreasonable not to? http://www.peterkreeft.com/topics/pascals-wager.htm
Notes: Let's look at Lenski’s Long Term Evolution Experiment and see what we can find after 50,000 generations, which is equivalent to somewhere around 1,000,000 years of human evolution.
Richard Lenski’s Long-Term Evolution Experiments with E. coli and the Origin of New Biological Information – September 2011 Excerpt: The results of future work aside, so far, during the course of the longest, most open-ended, and most extensive laboratory investigation of bacterial evolution, a number of adaptive mutations have been identified that endow the bacterial strain with greater fitness compared to that of the ancestral strain in the particular growth medium. The goal of Lenski’s research was not to analyze adaptive mutations in terms of gain or loss of function, as is the focus here, but rather to address other longstanding evolutionary questions. Nonetheless, all of the mutations identified to date can readily be classified as either modification-of-function or loss-of-FCT. (Michael J. Behe, “Experimental Evolution, Loss-of-Function Mutations and ‘The First Rule of Adaptive Evolution’,” Quarterly Review of Biology, Vol. 85(4) (December, 2010).) http://www.evolutionnews.org/2011/09/richard_lenskis_long_term_evol051051.html Mutations: when benefits level off – June 2011 – (Lenski’s e-coli after 50,000 generations) Excerpt: After having identified the first five beneficial mutations combined successively and spontaneously in the bacterial population, the scientists generated, from the ancestral bacterial strain, 32 mutant strains exhibiting all of the possible combinations of each of these five mutations. They then noted that the benefit linked to the simultaneous presence of five mutations was less than the sum of the individual benefits conferred by each mutation individually. http://www2.cnrs.fr/en/1867.htm?theme1=7
Now something is going terribly wrong here wd400! Tell you what wd400, let’s just forget trying to observe evolution in the lab, I mean it really is kind of cramped in the lab you know, and now let’s REALLY open the floodgates and let’s see what the almighty power of neo-Darwinian evolution can do with the ENTIRE WORLD at its disposal!
A review of The Edge of Evolution: The Search for the Limits of Darwinism The numbers of Plasmodium and HIV in the last 50 years greatly exceeds the total number of mammals since their supposed evolutionary origin (several hundred million years ago), yet little has been achieved by evolution. This suggests that mammals could have “invented” little in their time frame. Behe: ‘Our experience with HIV gives good reason to think that Darwinism doesn’t do much—even with billions of years and all the cells in that world at its disposal’ (p. 155). http://creation.com/review-michael-behe-edge-of-evolution Michael Behe, The Edge of Evolution, pg. 162 Swine Flu, Viruses, and the Edge of Evolution “Indeed, the work on malaria and AIDS demonstrates that after all possible unintelligent processes in the cell–both ones we’ve discovered so far and ones we haven’t–at best extremely limited benefit, since no such process was able to do much of anything. It’s critical to notice that no artificial limitations were placed on the kinds of mutations or processes the microorganisms could undergo in nature. Nothing–neither point mutation, deletion, insertion, gene duplication, transposition, genome duplication, self-organization nor any other process yet undiscovered–was of much use.” http://www.evolutionnews.org/2009/05/swine_flu_viruses_and_the_edge020071.html

KF, you're just repeating the same rubbish as everyone else here. Yes, metamorphosis in modern insects is all or nothing, but that's because metamorphosing insects have had 300 million years to create a greater distinction between the larval and adult forms. As for the rest of it. The caterpillar isn't "outright breakdown of cellular continuity from embryo to adulthood" adult tissues (imaginal discs) sit inside larvae, and adults can remember things that learned as larvae. It's not trute that things can only evolve if every step in a given path is advantageous, in fact, I'd happily wager much complexity arises from slightly detrimental mutation. The evolutionary secenario doesn't claim there was ever a caterpillar-like creature that added a butterfly-like stage to its life (a really bizarre idea if you know much about insects, actually). Given everything you've got wrong in the set up, I'm not going to dance to silly little "fill in the blanks" game. I've linked to papers that describe current thinking about the origin of metamorphosis, why don't you read them.wd400

F/N: Granville Sewell, Mathematician, summarises the logical puzzle for us in his ENV comment here:
The process of transforming a caterpillar into a butterfly is surely far more complex than anything ever accomplished by man. The information needed to control this process, stored somewhere in the caterpillar's cells, must be far greater than that stored in any man-made computer program. And explaining how this enormous program arose through many "5 or 6 character" improvements is even more challenging here, because now the intermediate stages are not just useless, they are fatal. Metamorphosis involves the destruction of the caterpillar: the butterfly, with an almost completely new body plan, is constructed from dissolved and recycled tissues and cells of the caterpillar. Now we are not talking about climbing Mount Improbable, we are talking about building a bridge across an enormous chasm, between caterpillar and butterfly . . . . Until construction of this extremely long and complicated bridge is almost complete, it is a bridge to nowhere. Unless a butterfly (or another organism capable of reproduction) comes out at the end, the chrysalis only serves as a casket for the caterpillar, which cannot reproduce. Now we do not have to simply imagine uses for not-quite-watertight vacuum chamber traps, we have to imagine a selective advantage for committing suicide before you are able to reproduce, and that is a more difficult challenge!
The answer to this logical puzzle is _________, and the observational evidence that adequately warrants such an amazing claim beyond reasonable doubt is ______________ . KFkairosfocus

WD: I notice, that you did not directly address the specific irreducible complexity and functionally specific, complex information challenges implied in my earlier note. But, those are pivotal, whatever one wants to make of circularity ridden just so stories about genetic reconstructions and concentrations of development processes in one stage. (And, remember the logic of too many genetic/molecular reconstructions is circular, assuming what is to be proved, and that is before we get to the problem of the contradictory trees of claimed descent that are obtained in general.) I want to emphasise the molecular soup aspect of the pupation phase, with particular reference to caterpillars, as this implies an outright breakdown of cellular continuity from embryo to adulthood, which obviously is NOT the case for incomplete metamorphosis. In short, I am highlighting the transformational aspect, even as the old kid's song puts it: "Bullfrogs and butterflies, both been born again . . . " Let me cite Ann Gauger (Developmental Biologist) and Paul nelson on the subject, from the video that accompanies the full form of the linked video preview. I have some hope that you will at least open your eyes to see that there is a challenge here that is being glossed over -- as seems all too usual: _____________ >> . . . it appears that the most ancient phyla were metamorphic from the beginning, based on the few larval forms that have been preserved. 6 This suggests that these Cambrian animals had not one but two or more develop- mental stages at the outset, a small and free-swimming larva, and a bot-tom-dwelling adult with little or no re-semblance to its earlier form. But how such transitions could have evolved, and from what, is completely unknown. In contrast, insects arrived on the scene much later, in the late Silurian or early Devonian, and apparently devel-oped metamorphosis secondarily. The most ancient insects were wingless, terrestrial animals that developed directly into mini-adults, and lacked any metamorphosis (this is called ametabolous—literally, “without changing”—development) . . . . It appears, based on some fossilized nymphs and adults and from what we know of their modern relatives, that from the beginning these insects had a partial form of metamorphosis (hemi-metabolous—literally, “part changing”—development). The nymphs resemble adults in many respects, but lack wings and reproductive structures. Through several successive molts their wings grow gradually, with fully developed wings and reproductive organs appear-ing only in the adult. Other familiar hemimetabolous groups include grass-hoppers and crickets. Insects that undergo complete metamorphosis, such as beetles, flies and ants, did not appear until the late Carboniferous or early Devonian. These insects have been fabulously successful. In fact, nearly 85 percent of all modern insect species have holometabolous—literally, “all changing”—development . . . . What distinguishes holometabolous species is their strikingly different life stages. The major stages of holome-tabolous (abbreviated Holo) metamor-phosis are (a) egg, (b) larva (often given a different name, such as “cater-pillar”), (c) pupa (or chrysalis), and (d)adult, in that sequence . . . . from an evolutionary stand-point, the problem of the origin of but-terfly metamorphosis—in particular, of the pupal stage—is really the problem of the origin of holometabolous meta-morphosis generally, not just in Lepi-doptera . . . . When an egg of a female Monarch butterfly is fertilized by the sperm of a male, that cell, and its many daugh-ter cells, set out on a long, targeted pathway: A to B to C—and so on, to Z, where Z is the adult form capable of reproduction, thus starting the whole cycle again. The pathway aims at the target of reproductive capability. Keep that in mind, because we’ll come back to it shortly when we consider the logic of natural selection. But there’s another important fea-ture to development—in all animals, not just butterflies—too little grasped, even by many biologists . . . . Developmental biologists know this “magic bridge” aspect to animal development ntimately. Early em-bryos, for instance, are often described by isolating fate maps for particular groups of cells. A fate map shows the ultimate or terminal destination, in the adult form, of cell lineages that first arise in the em -bryo, in positions that often scarcely resemble their final target. But to get to that target, the cells must follow a prescribed path, with unerring trajectories . . . . The entire process is re-quired; it can neither stop nor go off track. An embryo whose development is arrested midway or distorted in a major way will die: the end goal of re-productive adult will be lost. Butterfly development exhibits these precise pathways, but with the additional aspect of crossing a bridge of astonishing delicacy: namely, the chrysalis. Here, the Indiana Jones magic bridge dimension really does take one’s breath away, because dur-ing the pupal stage (in the chrysalis), the tissues and structures of the cat-erpillar are almost entirely dissolved away, digested by cell death processes (known as apoptosis and autophagy) into a molecular soup. The walker on the bridge crosses on a lane just wide enough for each footstep, with a chasm of death on either side—and the walker must keep moving. Out of the soup arises the adult form, with its wings, legs, proboscis, genitalia, eyes, anten-nae, and so forth. Could this developmental pathway have evolved via the natural selection of randomly arising variation, as pos-ited by neo-Darwinism? To answer that question, we need to look at what the process of natural selection requires— and what it cannot do, in principle . . . . Because natural selection de-pends (with condition 1, random varia-tion) on whatever happens to vary in a species, or not—and there’s no way of knowing before the variations occur, or even if they will occur—the process cannot look into the future. Unlike hu-man designers, therefore, who can visualize a distant target, the process of selection “sees” only the variations randomly arising in each generation, and their immediate selective out-comes. Thus, “life never evolves with foresight,” . . . . If a biological system requires multiple independent changes, for instance, no one of which individually confers a selective advantage, natu-ral selection cannot be the process by which that system came to be. That’s it: full stop . . . . A caterpillar-like species would never evolve in the direction of forming a chrysalis, dissolving its vital tissues in the process, unless—some-how—the variations were also occur-ring, and being preserved by natural selection, which would also enable that species to make it out of the chrysalis stage. And to leave offspring: condition 3 of natural selection, heritability, re-quires that variations be transmitted to one’s progeny. But as we inspect the pathway of metamorphosis, what we see is a magical bridge, where literally thou-sands of independent decisions need to be chained together for the process of transformation as a whole to work. Reproductive capability—one of the necessary conditions of natural selec-tion—lies on the far side of the gorge we are crossing. The caterpillar can’t leave offspring. Only the adult butterfly can do that. But to reach the adult, we need the caterpillar, and then we need to dis-solve it into a soup—inside a chrysa-lis where it cannot feed, move, or do much of anything, other than turn into a butterfly. If one wanted an example of a biological system that could never be explained by natural selection, butter-fly metamorphosis would stand at the head of the line. >> ____________ That is what needs to be cogently explained, explained on Blind Watchmaker Mt Improbable incrementalism, backed up by adequate observational evidence. TWO body plans, only one of which is reproductive, and to be bridged by a process that reeks of astonishing irreducible complexity and massive functionally specific complex organisation and information involving not a prebiotic soup, but indeed a molecular soup. The Blind Watchmaker, Mt Improbable explanation for such is _____________ . It is backed by the following observed evidence that answers to the above issues ____________ . And, on the assumption that the evidence of the Cambrian fossils speaks to similar cases, the similar explanation of how we move to such from the universal common ancestor is _______, and this is backed up by actual observational evidence such as ________ that indicates ____________ . Could you kindly fill in these blanks for us? KFkairosfocus

Each of these steps is obviously useless without the other steps in place. Worse than useless — deadly. Sure. So what? You are looking a modern organisms, not how they traits it modern organisms could evolve and what intermediate forms would look like. The evolution of metamorphosis isn't all worked out, which is one of th reasons it is so interesting, but comments like yours and KF's don't seem to be informed by what we do know about the process.wd400

wd400 @81:
Someone who evidently knows nothign about [metamorphosis] cited it as a problem for evolution, and I simply mentioned it’s not the problem they think it is when you understand that (1) normal insect development often involves considerable change from start to finish (think dragonfly nymphs – which start as under-water predators!) and (2) much of the biological basis for this change is homologous to the pupal stage in metamorphosing insects.
With all due respect, perhaps you don't understand the metamorphosis argument. The argument is not that (i) other insect processes don't involve significant change, or that (ii) there aren't homologous aspects in the pupal stage. It is objectively true that normal insect development does not mirror metamorphosis in all significant respects and that a few superficially-similar homologous aspects of the pupal stage don't provide answers to metamorphosis. That being said, one of the real problems for traditional evolutionary theory is that evolution is supposed to work through slight, successive steps. So we have a living, breathing organism that by all accounts is doing just fine. And yet for some reason it encloses itself in a cocoon, which, absent yet further development, would be an evolutionary dead end. And for some additional reason it then literally dissolves its body, which would be an evolutionary dead end. And for some additional reason is able to rebuild itself with a new body plan. And then escape the cocoon. Each of these steps is obviously useless without the other steps in place. Worse than useless -- deadly. So the existence of metamorphosis demonstrates the futility of trying to bring this system about through slight, successive changes. [We should note that many other systems also show this futility, but with metamorphosis it is perhaps a bit more stark.] So, yes, metamorphosis is a significant problem for traditional evolutionary theory. Now if someone wants to recur to saltation, or imaginary just-so stories, or plain old declarations of homage to the power of evolution, then the existence of metamorphosis is not likely to shake their deeply-held faith any more than the numerous other examples in biology would. But to an objective observer who is not wedded to an a priori commitment to a materialist creation myth, yes, metamorphosis is a significant conundrum.Eric Anderson

wd400 you claim that testing for the ability of proteins to evolve into new function, "is no a test of any mainstream idea in evolutionary biology". Yet the truth is that protein evolution, or severe lack thereof, is a major concern of 'evolutionary' biology,,,
Proteins Did Not Evolve Even According to the Evolutionist’s Own Calculations but so What, Evolution is a Fact - Cornelius Hunter - July 2011 Excerpt: For instance, in one case evolutionists concluded that the number of evolutionary experiments required to evolve their protein (actually it was to evolve only part of a protein and only part of its function) is 10^70 (a one with 70 zeros following it). Yet elsewhere evolutionists computed that the maximum number of evolutionary experiments possible is only 10^43. Even here, giving the evolutionists every advantage, evolution falls short by 27 orders of magnitude. The theory, even by the evolutionist’s own reckoning, is unworkable. Evolution fails by a degree that is incomparable in science. Scientific theories often go wrong, but not by 27 orders of magnitude. And that is conservative. http://darwins-god.blogspot.com/2011/07/response-to-comments-proteins-did-not.html Belgian Waffle - Douglas Axe - January 18, 2013 Excerpt:,, an article from Ghent University in Belgium claims a recent scientific paper has rescued evolutionary theory by solving the problem of evolutionary innovation.,,, Here's the concession: "An important unanswered question in Darwin's theory of evolution is how new characteristics seem to appear out of nowhere." Hmmm. Yes, I can see how this could be a problem for a theory of biological origins.,, ,,,here's the plain statement: "The preduplication [i.e., ancestral] ancMalS enzyme was multifunctional and already contained the different activities found in the postduplication [i.e., evolved] enzymes, albeit at a lower level." So, all we have here is a demonstration of what we already knew -- that evolution can adjust somewhat the relative preferences enzymes show for the molecules they already work on. Those aren't new activities, though, and this isn't a new result either. What would be really new and welcome would be for evolutionary biologists to begin taking the word new seriously. http://www.evolutionnews.org/2013/01/belgian_waffle068421.html Nature Paper,, Finds Darwinian Processes Lacking - Michael Behe - Oct. 2009 Excerpt: Now, thanks to the work of Bridgham et al (2009), even such apparently minor switches in structure and function (of a protein to its supposed ancestral form) are shown to be quite problematic. It seems Darwinian processes can’t manage to do even as much as I had thought. (which was 1 in 10^40 for just 2 binding sites) http://www.evolutionnews.org/2009/10/nature_paper_finally_reaches_t.html Stability effects of mutations and protein evolvability. October 2009 Excerpt: The accepted paradigm that proteins can tolerate nearly any amino acid substitution has been replaced by the view that the deleterious effects of mutations, and especially their tendency to undermine the thermodynamic and kinetic stability of protein, is a major constraint on protein evolvability,, http://www.ncbi.nlm.nih.gov/pubmed/19765975 Severe Limits to Darwinian Evolution: - Michael Behe - Oct. 2009 Excerpt: The immediate, obvious implication is that the 2009 results render problematic even pretty small changes in structure/function for all proteins — not just the ones he worked on.,,,Thanks to Thornton’s impressive work, we can now see that the limits to Darwinian evolution are more severe than even I had supposed. http://www.evolutionnews.org/2009/10/severe_limits_to_darwinian_evo.html
Related notes: A unsubstantiated Darwinian presupposition for the ability of proteins to evolve to new functions is simply 'not even wrong':
The Humpty-Dumpty Effect: A Revolutionary Paper with Far-Reaching Implications - Paul Nelson - October 23, 2012 Excerpt: Put simply, the Levinthal paradox states that when one calculates the number of possible topological (rotational) configurations for the amino acids in even a small (say, 100 residue) unfolded protein, random search could never find the final folded conformation of that same protein during the lifetime of the physical universe. http://www.evolutionnews.org/2012/10/a_revolutionary065521.html Physicists Discover Quantum Law of Protein Folding – February 22, 2011 Quantum mechanics finally explains why protein folding depends on temperature in such a strange way. Excerpt: First, a little background on protein folding. Proteins are long chains of amino acids that become biologically active only when they fold into specific, highly complex shapes. The puzzle is how proteins do this so quickly when they have so many possible configurations to choose from. To put this in perspective, a relatively small protein of only 100 amino acids can take some 10^100 different configurations. If it tried these shapes at the rate of 100 billion a second, it would take longer than the age of the universe to find the correct one. Just how these molecules do the job in nanoseconds, nobody knows.,,, Their astonishing result is that this quantum transition model fits the folding curves of 15 different proteins and even explains the difference in folding and unfolding rates of the same proteins. That's a significant breakthrough. Luo and Lo's equations amount to the first universal laws of protein folding. That’s the equivalent in biology to something like the thermodynamic laws in physics. http://www.technologyreview.com/view/423087/physicists-discover-quantum-law-of-protein/

wd400 tries to whittle evolution down to bite size nuggets for metamorphosis (an apparent miracle of entirely new body plan morphogenesis that even a child can grasp) and then finishes off his excuse making foray for his religion of Darwinism with this,,,
Once you understand that, it ought to be clear that, even if metamorphosis in a modern insect is an all or nothing affair, the evolution of the trait needn’t jump any unspannable gaps.
Such as the unspannable gap of transforming a single protein to a new function wd400?
The Evolutionary Accessibility of New Enzyme Functions: A Case Study from the Biotin Pathway - Ann K. Gauger and Douglas D. Axe - April 2011 Excerpt: We infer from the mutants examined that successful functional conversion would in this case require seven or more nucleotide substitutions. But evolutionary innovations requiring that many changes would be extraordinarily rare, becoming probable only on timescales much longer than the age of life on earth. http://bio-complexity.org/ojs/index.php/main/article/view/BIO-C.2011.1/BIO-C.2011.1 When Theory and Experiment Collide — April 16th, 2011 by Douglas Axe Excerpt: Based on our experimental observations and on calculations we made using a published population model [3], we estimated that Darwin’s mechanism would need a truly staggering amount of time—a trillion trillion years or more—to accomplish the seemingly subtle change in enzyme function that we studied. http://www.biologicinstitute.org/post/18022460402/when-theory-and-experiment-collide More from Ann Gauger on why humans didn’t happen the way Darwin said - July 2012 Excerpt: Each of these new features probably required multiple mutations. Getting a feature that requires six neutral mutations is the limit of what bacteria can produce. For primates (e.g., monkeys, apes and humans) the limit is much more severe. Because of much smaller effective population sizes (an estimated ten thousand for humans instead of a billion for bacteria) and longer generation times (fifteen to twenty years per generation for humans vs. a thousand generations per year for bacteria), it would take a very long time for even a single beneficial mutation to appear and become fixed in a human population. You don’t have to take my word for it. In 2007, Durrett and Schmidt estimated in the journal Genetics that for a single mutation to occur in a nucleotide-binding site and be fixed in a primate lineage would require a waiting time of six million years. The same authors later estimated it would take 216 million years for the binding site to acquire two mutations, if the first mutation was neutral in its effect. Facing Facts But six million years is the entire time allotted for the transition from our last common ancestor with chimps to us according to the standard evolutionary timescale. Two hundred and sixteen million years takes us back to the Triassic, when the very first mammals appeared. One or two mutations simply aren’t sufficient to produce the necessary changes— sixteen anatomical features—in the time available. At most, a new binding site might affect the regulation of one or two genes. https://uncommondescent.com/intelligent-design/more-from-ann-gauger-on-why-humans-didnt-happen-the-way-darwin-said/ Thou Shalt Not Put Evolutionary Theory to a Test - Douglas Axe - July 18, 2012 Excerpt: "For example, McBride criticizes me for not mentioning genetic drift in my discussion of human origins, apparently without realizing that the result of Durrett and Schmidt rules drift out. Each and every specific genetic change needed to produce humans from apes would have to have conferred a significant selective advantage in order for humans to have appeared in the available time (i.e. the mutations cannot be 'neutral'). Any aspect of the transition that requires two or more mutations to act in combination in order to increase fitness would take way too long (>100 million years). My challenge to McBride, and everyone else who believes the evolutionary story of human origins, is not to provide the list of mutations that did the trick, but rather a list of mutations that can do it. Otherwise they're in the position of insisting that something is a scientific fact without having the faintest idea how it even could be."

So we test the claim that metamorphosis evolved by assuming it and loking for similar genes? How do we test the claim that insect development evolved? Do brine shrimp go through such a developmental process? Ya see wd400, you cannot use one thing tat you cannot explain- ie insect development- to try to explain the evolution of something else that you cannot explain. Maybe, someday, someone will take some of these developing insects and see if they can get one to evolve into a metamorhosizing insect via trageted mutagenesis and artificial selection.Joe

wd400, I am astonished that insect metamorphosis would be touted as an example of the power of evolution. I just had to follow your first link and I landed on this gem:
We found that it [broad gene] is expressed throughout the nymphal stages, and that it is also required for change," said Deniz Erezyilmaz, a UW biology research associate. "So it looks like metamorphosis evolved in insects by restricting the expression of the broad gene to a short but intense period of change at the transition from larva to pupa.
Wow! I now see the error of my ways. How could I have been so thick? lol. Seriously, does anyone really think it is just that easy? Metamorphosis is such an all-or-nothing transition that it is akin to asking evolution to leap across the Grand Canyon. There are no offspring to try again until evolution get it completely right. Metamorphosis is the nigh icon for intelligent design. Stephensterusjon

wd400, the trouble with all your genetic similarity evidence, that you have placed so much confidence (faith) in, is that you don't actually have any empirical evidence that Darwinian processes can fixate even a single unambiguously beneficial mutation in insects, much less account for the massive amounts of new genetic information (ORfan genes) being found in forthcoming genome studies:
Experimental Evolution in Fruit Flies (35 years of trying to force fruit flies to evolve in the laboratory fails, spectacularly) - October 2010 Excerpt: "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 research really upends the dominant paradigm about how species evolve," said ecology and evolutionary biology professor Anthony Long, the primary investigator. http://www.arn.org/blogs/index.php/literature/2010/10/07/experimental_evolution_in_fruit_flies 'No matter what we do to a fruit fly embryo there are only three possible outcomes, a normal fruit fly, a defective fruit fly, or a dead fruit fly.

A technique called "saturation mutagenesis"1,2 has been used to produce every possible developmental mutation in fruit flies (Drosophila melanogaster),3,4,5 roundworms (Caenorhabditis elegans),6,7 and zebrafish (Danio rerio),8,9,10 and the same technique is now being applied to mice (Mus musculus).11,12 None of the evidence from these and numerous other studies of developmental mutations supports the neo-Darwinian dogma that DNA mutations can lead to new organs or body plans--because none of the observed developmental mutations benefit the organism. http://www.evolutionnews.org/2010/10/response_to_john_wise038811.html New genes in Drosophila quickly become essential. - December 2010 Excerpt: The proportion of genes that are essential is similar in every,, age group that we examined.

But we haven't-quite the opposite, in fact.,,, The upshot is that the chances of random mutations turning a bit of junk DNA into a new gene seem infinitesmally small. As the French biologist Francois Jacob wrote 35 years ago, "the probability that a functional protein would appear de novo by random association of amino acids is practically zero".,,, Orphan genes have since been found in every genome sequenced to date, from mosquito to man, roundworm to rat, and their numbers are still growing. http://ccsb.dfci.harvard.edu/web/export/sites/default/ccsb/publications/papers/2013/All_alone_-_Helen_Pilcher_New_Scientist_Jan_2013.pdf
Moreover, even if you did have a demonstrated mechanism (which you don't), metamorphosis occurs far earlier in the fossil record than Darwinists would predict:
The Enigma of Metamorphosis Is Hardly Limited to Butterflies - October 2011 Excerpt: Even more mysteriously, it appears that the most ancient phyla were metamorphic from the beginning, based on the few larval forms that have been preserved. This suggests that these Cambrian animals had not one but two or more developmental stages at the outset,,,, http://www.evolutionnews.org/2011/10/the_enigma_of_metamorphosis_is051541.html Metamorphosis Is Widespread - Ann Gauger - video http://www.youtube.com/watch?v=GkD-jd1imaI
A mathematician with years of experience programming computers, reflects on the problem facing the unguided, non-foresighted, Darwinian scenario with metamorphosis:
A Mathematician Explains the Irreducible Complexity of Metamorphosis - Granville Sewell - November 2011 Excerpt: Now we are not talking about climbing Mount Improbable, we are talking about building a bridge across an enormous chasm, between caterpillar and butterfly. ,, Until construction of this extremely long and complicated bridge is almost complete, it is a bridge to nowhere. Unless a butterfly (or another organism capable of reproduction) comes out at the end, the chrysalis only serves as a casket for the caterpillar, which cannot reproduce. Now we do not have to simply imagine uses for not-quite-watertight vacuum chamber traps, we have to imagine a selective advantage for committing suicide before you are able to reproduce, and that is a more difficult challenge! http://www.evolutionnews.org/2011/11/the_irreducible_complexity_of052461.html
Hey wd400, I have a 'metamorphosis' that you can actually believe in. In the bible it says:
Matthew 17:1-13 After six days Jesus took with Him Peter, James and John the brother of James, and led them up a high mountain by themselves. There He was transfigured before them. His face shone like the sun, and His clothes became as white as the light. Just then there appeared before them Moses and Elijah, talking with Jesus.
And in the bible it also says:
1 John 3:2 Dear friends, we are already God's children, but he has not yet shown us what we will be like when Christ appears. But we do know that we will be like him, for we will see him as he really is.
wd400, Is it really reasonable to believe that there can be 'metamorphosis' of us into beings of light?? Well, there is a 'seed of butterfly light' permeating our entire 'wormy' being that surely doesn't dampen the prospect of it being reasonable:
Humans Glow in (Emit) Visible Light - July 2009 Excerpt: Past research has shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive. In fact, virtually all living creatures emit very weak light, http://www.msnbc.msn.com/id/32090918/ns/technology_and_science-science/t/humans-glow-visible-light/
Moreover it is common for Near Death Experinecers to report as follows
Vicki's Near Death Experience (Blind From Birth) Quote 'I was in a body and the only way that I can describe it was a body of energy, or of light. And this body had a form. It had a head. It had arms and it had legs. And it was like it was made out of light. And 'it' was everything that was me. All of my memories, my consciousness, everything.' - Vicky Noratuk

wd400 @75: Just curious how we should conclude that "Metamorphosing insects evolved from direct developers like grasshoppers bugs" when the cited article simply points to the fact that a gene in one insect is also involved in a function in a different insect. I presume the other evidence is along similar lines: noting similarities between insects.Eric Anderson

In fact, these a rather nice review of the whole idea which is open acssess - see especially the last section about genetic evidence for this idea.wd400

Lots of ways, Joe. Here's one nice study looking at one aspect, then read about juvinile hormone, consider the presence of imaginal discs in the caterpillar (something for KF to think about too, actually). As we get more insect genomes this will become more and more interesting, for now we have only a few holometabolous insects, and those are mainly flies.wd400

Just how the heck can we test that claim?Joe

WD: Kindly, contrast a caterpillar and a butterfly. While at it, describe what happens/would be seen if you cut open a pupa at various stages. (Cf. vid.)KFkairosfocus

To see just one facet, consider how in many insects with complete metamorphosis, the larval body plan vanishes without reproduction and is replaced by another through a transformational stage; where the new plan is the one that reproduces. Metamorphosing insects evolved from direct developers like grasshoppers bugs etc. They just compact their developmental in one stage (the pupa) - splitting the development like this, insteaed of letting it run out across many "nymphs" allowed more radical changes in each form to evolve - but the adult insect is not "a new plan".wd400

macroevolution need a new machine. a new machin in car)air condition)need minimum2-3 parts. the biological mashin also. that give us 2-3 protein or a chance of 1 in 2^200 tryes for 2 proteins 100 aa longmk
