What about the problem with the statement in EE about Haeckel's embryos, for example?


We’re juggling relative terms -– “many” versus “some” versus “a few” textbooks have used Haeckel's drawings, or derivatives of them.  I don’t know what textbooks you have in your office.  Are any of them in this brief survey?

http://www.discovery.org/a/3935

Donald Prothero just re-published the Romanes 1910 figure, based on Haeckel, although he attributes the material to von Baer; he also supports the validity of ontogeny recapitulating phylogeny.  So use of the drawings persists.

What needs to be done -– and we’ve haven’t done it -– is a thorough (exhaustive) survey of high school and college textbooks, so that actual frequency of usage of Haeckel-derived drawings, and their context, can be determined.  The document I linked to provides a start, but it’s not exhaustive.

I could see changing “many” (on p. 69) to “some,” but I’d have to persuade my co-authors.

Paul

What would be more interesting than your list would be a factual accounting for HOW MANY books were examined before Casey could find these 10, 3 of which are actually multiple editions of the same book. As I indicated in my previous post. I took 21 books that I had in my office; three of them had the figure, and NONE of them indicated that Haeckel was correct. The data do not favor your interpretation.

Secondly, as documented previously on this very thread, the Futuyama book that you and Casey cite does not indicate that your interpretation is accurate. Again, the data do not favor your interpretation.

ETA - See this link for a detailed refutation of the Haeckel strawman, performed by a card-carrying developmental biologist.

Well, that's where RC becomes problematic, as I think Alb and the other professional biologists reading this thread know.

I appreciate the amplification.  We'll come to to the peer-reviewed business further on, I expect.

Ahhh, right the onspiracy-cay. Say no more.

Is it morally wrong to evaluate current theories of evolution, in the light of the available evidence?

Paul, if you actually did that, it would not be morally wrong, but you're not doing so in light of the available evidence. You're avoiding evidence in favor of the most dishonest sort of quote mining.

In fact, my question that you have yet to answer is about the available evidence:

Funny thing about the reptile-mammal illustration comparison, which Afarensis and other find puzzling and irrelevant.  Several people who did not know that the fossils were being scaled (without their knowledge), to make the morphological transition appear smoother, have told me they regard this practice as objectionable.

Why weren't we shown just how different in size these groups were? they ask.

Because changes in size aren't a big deal genetically:

http://www.sciencemag.org/cgi/content/abstract/316/5821/112

Do you have some data that suggest that size changes are a big deal?


Note that I supplied evidence and requested for evidence, and you run away from it, showing that you have zero interest in evaluating anything in light of available evidence.

If you're about evidence, why would you rely on quotations?

My points still stand, Paul, if you'd just read them. I don't believe you've actually directly responded to a single one I've made, or you'd realise that my problem is not with you presenting truth, but presenting propaganda. As someone else pointed out, you aren't equipping children with the ability to critically analyse; you're just making them do it, to what happens to be the one subject which creationists don't want their kids to learn.

Alb,

Thanks for this formulation:

   
Quote
1.  Topic A has been discussed in creationist writings, either historically or currently.

2. Topic A has been shown to be a quote-mine, a strawman, easily accommodated by modern evolutionary theory, or otherwise non-controversial in the minds of modern evolutionary biologists.

3. No new data relevant to Topic A, either casting new doubt on modern evolutionary theory or that is unable to be accommodated by modern evolutionary theory, has been provided by competent scientists and published in the peer-reviewed mainstream scientific literature.

4.  Thus, topic A is not material fit for a public school science textbook.


"Quote-mine," "strawman," and "easily accomodated" leave considerable room for debate, of course (but that's OK -- debate makes life interesting); in any case, I accept this as grounds for ongoing discussion.

I'll be out for the remainder of the day, but will try to return to the discussion tomorrow morning.  Thanks to all involved for the exchange.

Hi Paul

Does George Miklos have a theory of why there should be moths?  Is this something we can expect to see the new generation of Fundie Homeschoolers students using your text book?  Is one of these socially awkward young crusaders finally going to answer the question of why there are goldfish?

Somewhat OT, but speaking of embryology, and Haeckel:

In my lifetime, I've been a vocal supporter for both YEC and evolution, but only recently (around the time of the Dover trial) have I made an earnest, intellectual attempt to understanding "both sides of the debate".

Since my knowledge of biology was limited, I decided to use an analogy (ToE:ID::Lewis::MO) as a guide.

ID/creationism/'teachthecontroversy'/'academicfreedom' has failed utterly and completely the test. For example, take embryology: if I go to working scientists, science writers, and professors I get the following information:

http://scienceblogs.com/pharyng....aki.php
http://scienceblogs.com/pharyng....yng.php
http://www.talkorigins.org/features/whales/

When creationists comment at all about embryology they dwell nearly exclusively on Haeckel's drawings, as if the last century's worth of research didn't exist.

Paul Nelson, no, I haven't read EE nor will I.

Nor do I read pornography nor Barbara Cartland romance novels.  I haven't read Behe's books nor Dembski's nor will I.  For that matter, I haven't read much of Dickens, although I might.

I did flip through Icons of Evolution and Darwin's Black Box at Barnes and Noble, but both books were too stupid to either buy or read.

The point it, my dishonest creationist hack Paul, is why should I read your dreck?  It's crap from stem to stern.  In fact, I'd rather read Barbara Cartland because she's at least honest in writing bodice ripping yarns, unlike you.

I've read enough about EE to know it's pure crap and I find your twisting of Valentine's research intellectual slander.  Furthermore, your continued participation in this forum is only an indication of your abject stupidity.

So, dishonest and stupid, Paul.  No wonder you can't hold a day job.

As it happens, I have a copy of Prothero's book. Does he really "support the validity of ontogeny recapitulating phylogeny?"

Let's see here.......(flips through book)
Starting at the bottom of page 109, after explaining what the phrase means; i.e. embryonic development repeats evolutionary history:
"To the limited extent that von Baer had shown 40 years earlier, this is true. But embryos also have many unique features (yolk sac, allantois, amniotic membranes, umbilical cords) that have nothing to do with the evolutionary past and are adaptations to their developing environment. Thus it is dangerous to overextend the evolutionary implications of the stages in an embryo, but they are useful guides nonetheless."

Sounds bang on to me.

then on page 110, bringing up matters near and dear to us all:
"Creationists, such as Jonathan Wells (2000), in their eternal effort to mislead the uninitiated and miss the forest for the trees, will crow about how the biogenetic law has been discredited. But Haeckel's overenthusiasm does not negate the careful embryological work of von Baer that shows that many features of our past evolutionary stages are preserved in our embryos. Wells, in particular, nags about how some of Haeckel's original diagrams had errors and oversimplifications, but this does not change the overall fact that the sequence of all vertebrate embryos show the same patterns in the early stages, and all of them go through a 'fish-like' stage with pharyngeal pouches (which become the gill slits in fishes and amphibians) and a long fish-like tail, then some develop into fishes and amphibians and others lose these features and develop into reptiles, birds, and mammals. Wells' deceptive approach is nicely debunked by Gishlick (www.ncseweb.org/icons/icon4haeckel.html).
  If you had any doubts that you once had ancestors with fish-like gills and a tail, Figure 4-11 shows what you looked like five weeks after fertilization. Why did you have pharyngeal pouches (predecessors of gills) and a tail if you had not descended from ancestors with those features?"

And then Prothero shows a picture - no doubt PhotoShopped - of an actual human embryo showing just those features described.

Sounds to me like Prothero carefully put everything into context.

Note: Any errors/typos be the fault of my own self.

Actually, Jim -- I could deliver your copy of EE personally.  I'll be lecturing (with Angus Menuge) at the University of Wisconsin-Milwaukee, on April 1, 2008.  Kenosha isn't that far away...

Thanks, but I'm not interested in reading yet another creationist tract thinly disguised as science. It's been demonstrated time and again that you're a compulsive liar. It's very convenient for you to say, "Ha! You haven't read the book so..." but the whole point here is that we've all read the book without seeing it.

Tell you what: you open the "Debate" page on the EE website to unrestricted comments (within reason, of course) and I'll read the book and comment there.

Hi, Paul

Coincidentally, Cedarville University, the home of one of your reviewers
Quote
John Silvius, Ph.D.
Professor of Biology
Cedarville University
Cedarville, Ohio

is the subject of an interesting article in the Chronicle of Higher Education. PZ has a new post about this, and links to the article. If you don't subscribe to the Chronicle, let me know, and I'll send you a copy. But the upshot is that two professors there were dismissed because of their disagreement over a theological detail that probably makes sense to you, but not to me. Fortunately, according to the Chronicle,  
Quote
The statement then said that the university's "commitments to the inerrancy of Scripture, to its historic doctrinal position, and to its conservative theological heritage have not changed."

Does it make you just a little uneasy that this sort of institution seems to be the only place where your "inquiry-based textbook" has been vetted? Whatever happened to "teach the controversy", and academic freedom, and all that?

I don't have a copy of the book, so I'll refrain from commenting on things about which I am ignorant. I'd recommend it to you as well.

How about you answer the other questions that are building up here, rather than starting a new discussion?

I'll be responding to JAM's objection about the genetics of body size next.

Jim Wynne and Alb asked about why the Debate page at the Explore Evolution website was inactive.  Short version: I wanted a discussion board there, like this one, with no (or only light -- e.g., no vulgarity) moderation.  Others disagreed, and there the issue has stalled.  Given however that the work of responding to critics would probably fall largely (or entirely) to me, as it has in this thread, I decided to continue participating here until my own webpage, www.bioadagio.com, is active.

Once www.bioadagio is up, there will be a separate page there for open, unmoderated discussion of Explore Evolution.

Well, in my mind you haven't yet satisfactorily answered the question about why EE says that "many" high-school and college-level biology textbooks include Haeckel's figure and imply that these textbooks are misleading about the interpretation and history of that figure. As previously mentioned, I checked all 21 of the intro biology textbooks in my possession last summer, and found that three of them mentioned Haeckel. Furthermore, all of them had the correct interpretation and history for his infamous figure.

I am now in the process of reviewing textbooks for next fall, since the edition that we are using is out of print. I have checked those as well. Here's more ammunition for my side, a list of textbooks and how they treat Haeckel and his embryos.

1) Starr, Evers & Starr, Biology: Concepts and Applications, 7/e - Haeckel is not mentioned in the text; the infamous figure is not reproduced. The version of this textbook "without physiology" also has no mention of Haeckel..

2) Enger, Ross and Bailey - Concepts in Biology, 13/e - Haeckel is not mentioned in the text; the infamous figure is not reproduced.

3) Mader, Concepts of Biology, 1/e - This is an interesting case. Haeckel is mentioned in the index, where it indicates that you need to go to p. 710 to read more. Unfortunately, page 710 is in the ecology section; there is no mention of Haeckel on that page. He is not mentioned in either the embryology section or the evolutionary biology section. Another mark against your statement about how this misinformation is spread in "many" biology textbooks.

4) Hoefnagels, Biology: Concepts and Investigations, 1/e - Haeckel is mentioned on p. 318; the infamous figure is not shown. The text indicates that Haeckel fudged the figure in a couple of ways; in other words, it represents it accurately, contrary to the assertion in EE.

5) Campbell, Reece, Taylor, Simon and Dickey, Biology: Concepts and Connections, 6/e - Haeckel is not mentioned in the text; the infamous figure is not reproduced.

6) Krogh, Biology: A guide to the natural World, 4/e - Haeckel is not mentioned in the text; the infamous figure is not reproduced.

7) Presson & Jenner, Biology: Dimensions of Life, 1/e - Haeckel is not mentioned in the text; the infamous figure is not reproduced.

In all cases I looked in the index, and also in the embryology and evolutionary biology chapters.

So I can add 7 more textbooks to the 21 previously examined. In only one of these is Haeckel discussed in the "evidence for evolution" section, and in that case the author accurately reflects the state of understanding in the 21st (and 20th, and most of the 19th) century. Thus in the 4 (out of 28 total) books where Haeckel appears in the text, all of them accurately describe his work and the relevance of his work to modern evolutionary biology.

What more will it take to convince you that the use of "many" in EE is inaccurate? Can you stop beating that dead horse long enough to step out of the fine pink mist you are creating and see reality?

Please pass this along to your coauthors as well.

I'm not albatrossity, but I would say no.  There are much better figures out there.

Enough about the mote in Prothero's eye, though.

For example, you claim Prothero has confused von Baer's claim with Haeckel's.  It is clear he has not.

You claim the figure caption is wrong - it is not.  You fault it for what it doesn't say.  This is a book about fossils primarily, after all, not one on embryology
or developmental biology.

The first link doesn't support any argument that embryogenesis did not evolve by descent with modification.  I have no idea what you mean by "conservation of embryogenesis".

Keeping this on topic, is there a page in Exploring Evolution that deals with embryology?  :)

Yes, in point of fact there is. Leans heavily on Wells, misunderstands a paper by Sedgwick, mentions an interesting paper by Richardson et al (which I am trying to find a copy of), trots out the "most textbooks use Haeckel's drawings" (specifically mentioning Futuyma - which is BS) nonsense, among other things. All in all, it was even worse than the stuff on fossils...

Alb,

If the evidence shows that only a small percentage of textbooks use Haeckel-derived figures, I'll urge that we change "many" to "a few."

Tracy, Prothero's term "well-developed gills" is a character found in adult fish (and some amphibians).  The term "fish-like," which Prothero repeatedly uses, refers to fish -- again, the morphological standard of comparison is an adult organism, not an embryo.  This is classical Haeckelian recapitulation, and not von Baer's view at all.

Prothero's caption reads:

 
Quote
As embryologist Karl Ernst von Baer pointed out in the 1830s, long before Darwin published his ideas about evolution, all vertebrates start out with a very fish-like body plan in embryology, including the predecessors of gills and a long tail.  As they develop, many lose their fish-like features on their way to becoming reptiles, birds, and mammals.


This is wrong on multiple counts.  Von Baer did not think that embryos passed through stages that resembled (as "fish-like" implies) the adults of other species.  In fact, the fourth of his laws explicitly denies this; von Baer rejected the common ancestry of the animals.  And "starts out" is false: the stage (mis)represented in the Prothero figure is actually well into vertebrate development.  Egg sizes, cleavage patterns, and modes of gastrulation are profoundly different within the vertebrates.

The new edition of Explore Evolution will include significantly expanded bibliographic resources on the relationship of embryological evidence to theories of common ancestry.

More tomorrow, on JAM's genetics of body size question.

Also: are we to pretend that there's no difference between gills and gill slits, and that mammalian embryos don't have gill slits?

Second, the embryology of the whale, examined in detail, also provides evidence for its terrestrial ancestry. As embryos no less than as adult animals, whales are junkyards, as it were, of old, discarded features that are of no further use to them. Many whales, while still in the womb, begin to develop body hair. Yet no modern whales retain any body hair after birth, except for some snout hairs and hairs around their blowholes used as sensory bristles in a few species. The fact that whales possess the genes for producing body hair shows that their ancestors had body hair. In other words, their ancestors were ordinary mammals.

In many embryonic whales, external hind limb buds are visible for a time but thendisappear as the whale grows larger. Also visible in the embryo are rudimentary ear pinnae, which disappear before birth (except in those that carry them as rare atavisms). And, in some whales, the olfactory lobes of the brain exist only in the fetus. The whale embryo starts off with its nostrils in the usual place for mammals, at the tip of the snout. But during development, the nostrils migrate to their final place at the top of the head to form the blowhole (or blowholes)

Afarensis,

I'll send you a pdf of that paper by Richardson, along with his more recent work, if you can give me an email address to use.

Paul,
You can send it to:

afarensis@scienceblogs.com

Thanks much!

PaV: I suppose for me to be pried away from what I do to focus long and hard on that particular problem would take, quite honestly, hundreds of thousands of dollars to begin to pique my interest.

Paul while you are busy checking facts, can you let me know if Of Pandas and People Explore Evolution is going to provide a theory of why there might be moths, since you like to trumpet quotes that emphasize the fact that Darwinism (whatever that is) does not have any theory to explain this?

This would be a fine example of what ID can offer.

Alb,

If the evidence shows that only a small percentage of textbooks use Haeckel-derived figures, I'll urge that we change "many" to "a few."

Unless you have data to the contrary that you haven't shared here, I don't think that there is any doubt what the evidence shows. That figure appears in a small minority of modern introductory biology textbooks.

In addition, I think that the evidence shows that NONE of these textbooks perpetuates the error that Haeckel made. So even if that figure or a facsimile appears in a modern textbook, the text in that textbook seems to also negate the arguments made in EE. Rather than change the wording, I suggest that you drop the argument as yet another example of "refuted creationism".

I'll look forward to seeing some changes in the second edition.

thanks

If, I repeat, If, this happens, I nominate Albatrossity for the Nobel Effin Peace Prize.*

Arabs and Jews, Obama and Clinton, Klingons and The Federation, Spitzer and Illegal Prostitution Rings, getting them together, just doesn't compare to actually getting a grudging concession from an ID Creationist on Haeckel's Effin Embryos ™.

*Sorry, Paul. I considered a dual nomination, ala Begin and Sadat, but Dave had to work so hard to get you to move an inch, that I just can't justify it.

Don't count on it.  Remember that he only said he would urge the co-authors to make the change.  Classic good cop line: "Sure, I see your point, but I can't speak for my co-authors.  I mean, I agree, but, you know, that Stephen Meyer?  He is a loose cannon.  I can't control him and I just never know what he is going to do."

Think Danny Glover and Mel Gibson in "Lethal Weapon."
