Wholly Natrualistic Alternative To Neo-Darwinism?

Comparative embryology shows that early embryos have more features in common than later embryos. That lead Haeckel to propose the existence of a phylotypic stage of development

No, the claim in the hour-glass model is the earliest stages are more diverse but become more similar in the middle and then more diverse again: hence the hour-glass.

Please explain how this is evidence of evolution and whether you think it is real, now that you know what it is.
 
So Dinwar, you actually posted an article highlighting Haeckel's forgeries prominently and then suggest I take you and the article seriously, and that evos have moved on past Haeckel.

:jaw-dropp

Not all of his drawing were forgeries.

Haeckel was apparently a good researcher and got many of the first drawings of embryos at different stages of their growth.

He became a bad scientist when he created additional drawings that were not actually of embryos, but what he wanted them to look like to fit with the theory he wanted to be true.

The other real drawings of actual embryos can't just be thrown out. They are accurate drawings showing things we can see again in many later pictures. Your thought seems to be "He was wrong once therefore he's always wrong therefore science is always wrong therefore my god is right."

READ THE LINK. IT ANSWERS YOUR QUESTION. Look beyond the fact that the article happened to use a popularly-known drawing as an illustration--that website tends to use artist renderings all time tim, with all of the inaccuracies that those imply. Someone did something stupid and used a known fraud. Doesn't impact the article at all.

Though it IS telling that you focused on that, to the exclusion of the article. Well done there, randman--way to show that you're the better scholar. :rolleyes: Your God forbid you actually think through why this source would do what it did....

Even if it was the fraudulant diagram, it doesn't matter. It's nothing more than a well-known picture to draw attention to the article, nothing more. It's not even a part of the article--Haeckel gets a brief reference as the person who developed the idea, than it goes into genetics and modern embryology. There's nothing wrong with giving credit where credit is due; even frauds can be right. Including this picture is, worste case scenario, nothing more than a simple error in judgement on the part of an editor.

Sure they can. We have much, much better data now. Haeckel's pictures are just a bit prettier. It's like including old evolutionary trees in articles that touch on phylogeny--there was a certain amount of artistry to scientific diagrams in the past, which was often at the expense of the data and which has fallen by the wayside in science because of that. Science REPORTING, on the other hand (which randman doesn't differentiate between science reporting and scientific research), has no such qualms about including pretty but inaccurate pictures.

Well... I meant the good drawings can't be thrown out just because some others were faked.

They certainly can be thrown out when newer pictures are better.
 
Fair enough. :)

What actually has happened is that EVERYTHING was thrown out, for a long time, in terms of embryology because of Haeckel. No one wanted to discuss the evolutionary implications of embryology for a long, long time, because ANY embryological evidence was viewed as Haeckel. Completely false, but such over-reactions aren't unusaul in science. It's one of the reasons textbooks (which, I want to emphasize, NEVER show the current view of ANY field) used Haeckel's drawings for longer than they should have--they had no other options, because the scientists weren't comfortable asking the questions for fear of being accused of supporting fraud.

Please explain how this is evidence that ToE is false and that that falsity is evidence of Intelligent Design.

Please also show evidence of a designer.
 
Kot, I don't have time to waste on your long posts that skew the facts. Suffice to say, you are just wrong.

In short, you continue your proud tradition of dodging questions, refusing to give evidence for your claims, lie, and restate positions that have been consistently shown to be wrong. I suppose that in Davison-land, this counts as a victory for the creationists/IDers/frontloaders-a-la-Davison.

I note also that my prediction came true. Fancy that.

Randman: I can condense my last post to this simple, one-paragraph question:
Can you or can you not present evidence that Ludwig Rütimeyer, author of the first known critique and exposure of Haeckel's drawings was a creationist, IDer, or at least would have been counted as one had he lived to day, or alternatively show that another person who would be counted to one of those categories published a critique or exposure of Haeckel's darwings prior to Rütimeyer, or is your claim that the first criticism of Haeckel's drawings came from within the creationist camp simply not correct, and if so, will you admit it?


For example, evos specifically argued that non-functional DNA was particularly strong evidence for evolution because they argued there was no rationale way for similar sequences to have appeared without being passed on via common ancestry.

But at the same time, they argued that functional DNA was also strong evidence for evolution, no? Or is it your position that evos used to argue that only non-functional DNA was evidence for evolution, whereas functional DNA was not? Otherwise, it is just, as I made clear to you this spring, a case of moving a particular sequence of DNA from the category "non-functional DNA that is strong evidence for evolution" to the category "functional DNA that is strong evidence for evolution".

The label we put on it, again, does not matter, as long as the data behaves as we would expect or predict if evolutionary theory works. Or is it your understanding that the data suddenly changed once it was realized that a particular sequence was not non-functional?

of course, they were wrong on many counts. First, even non-functional DNA may be more likely to mutate into a certain pattern but the larger argument was that the DNA would be found to be functional. You likely cannot figure it out from here but should be able to.

Again, if I am so vastly ignorant of these matters, whereas you are so extremely knowledgeable, why not educate me? Is it because your opinion on this is as solidly founded as your opinion that Rütimeyer was a creationist, based on a single line of text by Darwin?

I can certainly understand why non-functional DNA would be considered strong evidence for evolution. I can also understand why functional DNA would be considered strong evidence for evolution. What I cannot understand if why sequences that behave according to the predictions of evolutionary theory magically stop doing so as soon as we change the label on them due to increased knowledge. I can understand the logic of the real world, but you prefer the logic of Davison-land, and if you want to make yourself understood, you will need to explain this logic better.

Repetition of functional sequences is explained by function of design.

Possibly. It is also explained by the theory of evolution, which is more parsimonious, and thus preferred.

Oh, and as far as nested hierarchies, if molecular data is inconsistent with it, what do evos do?

The longest debate we had, you and I, this spring, was over whether or not you could actually show any evidence whatsoever for your claim that there are groups in published phylogenies that cannot be explained by evolutionary theory. Over the entire time we discussed this, your evidence amounted to "I have already shown you a pile of evidence". I challenged you to chose any published phylogenetic tree you wanted, identify the groups recovered in it that would not, indeed could not, be predicted by evolutionary theory, explain why, and explain how they are predicted by Davison's god-based front-loading idea. I am still waiting for that phylogeny.

Do they drop the argument?

Nah.

Why should they? The only was data does not give a nested hierarchy is if it is all identical, and thus forms a great basal polytomy, but that only means that more or another form of data is needed. It may be okay where you come from -- as evidenced by your behaviour -- to simply drop difficult questions and walk away, but for a scientist, simply not knowing is not enough. If present data cannot explain a phenomenon, the strategy of choice is to get more data, not to pin the phenomenon on god, as for instance Davison does.

Here's a little illustration though not of Miller and Levine's textbook but of a later one.
http://www.discovery.org/scripts/viewDB/filesDB-download.php?command=download&id=1224

And, surprisingly, it differs from Haeckel's drawings in almost every part. Why do you suddenly present evidence that disproves your own claims? Have you changed your mind?

My guess is "no", because you have shown that picture before, and then, as now, this was because you, like Davison, believe "similar" and "identical" are the same thing.

Well, I said they used them, and I was right. You are trying to suggest that since they elaborated (maybe, it's hard to tell with the 1994 drawings), then they didn't use them, but that's just adding a qualifier I did not add.

Plus, the drawings are virtually identical anyway.

Oh my, according to this marine fauna field guide I am reading, God is a kind of Gadiform fish, with a white lateral line on a grey-green spotted background, a small beard, and three dorsal fins! Funny, they have called God "Cod" in this book, but it's virtually the same!

Reality, if you USE them to base your drawings on them, you USED them. Already explained that a long while ago on other threads.

To claim that you "explained" is to paint yourself in too charitable a colour. You certainly reiterated it.

You will notice, upon review, that this repost is not as clever as you believe it to be. Here it is, in context:

The reality is embryology doesn't show us much of anything as far as evolution.

I like this quote. It neatly illustrates the vaccuity of randman's thoughts on this issue. He believes that embryology has nothing to teach us about evolution. This isn't because it's true--ask any embryologist to see how, frankly, stupid such a statement is. It's because "evos"--meaning, apparently, any non-Creationist who disagrees with randman's view of evolution--haven't found it yet. This nicely illustrates that the overwhelming majority of those who oppose evolution are merely arguing against a theory they know little of, without doing their own research. If randman had, he'd have run up against numerous ways in which embryonic development plays a major role in evolution.

Ok Dinwar, how does the hour-glass model demonstrate evolution?

And is the hour-glass model even true?

Seems this answers your question quite nicely. And it's even simple enough for you to read the whole thing!!

Now that I've dealt with your pet concept in embryology, care ot look up Gould's book on the subject? Embryology is more than just the phylotypic stage, after all--it's everything from conception to birth (and in some case, well after birth). Are you going to tell me that you think the ONLY thing that has ANY use in evolutionary analysis in that WHOLE time is the phylotypic stage? How about, oh....the amniotic egg, live birth, the evolution of the placenta, all that? Or are you going to do your typical trick of picking one thing out of a huge and diverse field and declare that that is the One True Theory of that field, ignoring all others and belittling anyone who dares to say that perhaps you should look at the rest of the field?

So explain please how they are not virtually identical, and also answer the question now twice put to you on the hour-glass model.

I answered that question, randman. You didn't listen. I have a feeling you're not even reading posts--just skimming them for key words.

How about answering my questions first?

How is the hour-glass model evidence for evolution?

Is it real?

Notice that Dinwar did not at any point say that the hourglass model is evidence for evolution, or even that it is real. You claim that embryology -- as an entire field -- "doesn't show us much of anything as far as evolution", and Dinwar points out that this just shows that you know nothing about embryology and what it shows or doesn't show. You then get hung up on one historical detail of embryology, thereby proving Dinwar's prediction well-founded:

Or are you going to do your typical trick of picking one thing out of a huge and diverse field and declare that that is the One True Theory of that field, ignoring all others and belittling anyone who dares to say that perhaps you should look at the rest of the field?

I put it to you, randman, that if you have any aspirations at all to be even remotely consistent, then you will allow Dinwar not to explain or provide evidence for claims s/he didn't make, in the same way that you only very rarely see fit to provide evidence for the claims you actually make.
 
I answered that question, randman. You didn't listen. I have a feeling you're not even reading posts--just skimming them for key words.
This does seem likely, I think he skims them for something he recognises or can search for on the IDiocy websites, so he can post something superficially relevant in reply.

I agree. Most of his references are from IDoicy sites and the stuff that isn't is cherry picked.

How can you even suggest such a thing! Has he not showed us convincingly over the last year that his understanding of evolutionary science, embryology, palaeontology, taxonomy, phylogenetics, and biology in general is orders of magnitude removed from that of us evos? How can he not have convinced you that the reason that he refuses to substantiate any of his claims is that we wouldn't understand the data if he showed it to us?

That's why we get these dumbed-down replies: we couldn't understand the real, secret, vast amounts of data that randman is referring to when he makes his claims. Sure, it may look buffoonish when his claim that Ludwig Rütimeyer would be considered a creationist by today's standards is based entirely on a wikipedia articles based on a published article that says the reverse, and one line without any context in a letter to Rütimeyer from Darwin, but that's just on the surface. Below this, but kept hidden from lesser minds such as us, there is a cavernous cauldron of evidence in support of randman's claim, which we would surely be permitted to peruse, had we only put our minds to the task of truly, genuinely trying to understand that evolutionary theory predicts that there should be multi-cellular animals evolving into bacteria even as we speak, that half a wing is of no use, and that maybe, just maybe, God did it.

I am shocked, Catsmate and Dinwar, that you would even suggest that randman's part of the discussion does not rest on a solid foundation and a willingness to read through and debate purportedly salient points. Shocked!

ETA: And now kritikker as well! Outrageous!
Well, you know the old front-loading adage: "One person reaching a conclusion means that conclusion is a fact; another person supporting the first person's conclusion is an established fact; but three people agreeing on something means they are lying."

Hey hey hey Kotatsu, don't lump me in with you crazy scientist types. I may not know science but I know what I likes and Neo-Darwinianianism ain't it!
 
Krikkiter,

Thanks for those links, esp. the middle one.

This entire discussion reminds me of "Piltdown Man", and as such is a simple non sequitur and a rusty and time worn diversionary tactic.

The basic form of the "argument" is, "scientist x committed fraud, therefore..." or "scientist y was ultimately proven wrong, therefore...".

The only valid conclusions from the above are that scientists sometimes commit fraud, or that scientists are sometimes proven wrong.

Can we just stipulate to those two conclusions and move on?


Not on your life! randman must have bet his superannuation on this.
 
Following a brief discussion with another member, I looked up the papers of randman's idol Professor Emeritus John A. Davison. He's always a bundle of laughs in the way that he believed that when a critic of Darwin expresses an opinion on something, this is incontestable proof that this something is true, whereas when a non-critic of Darwin expressed an opinion on the same thing, he is blinded by ideology. Also: he believes that English names for morphological structures is a clue to homology and that maybe we should consider that God did it.

Anyway, looking through his New Essays, I came upon this wonderful insight into how Davison works:

The last myth to be exposed is the notion that oil is a fossil fuel.

Davison approaches this claim in his normal manner, by claiming that there are many different kinds of oil that are produced by metabolism in living organisms:

Oil, a generic term, can be produced by living organisms. Olive oil, castor oil, cod liver oil etc are all products of the metabolism of living organisms and so it was only natural that subterranean oil was also assumed to be the product of once living creatures, for some bizarre reason in the popular culture – dinosaurs.

He adds some assertions which fit into his god-based worldview, but does not lower himself to actually back this up with any references:

We now know that oil exists deep in the earth far below any levels that could possibly ever have been associated with surface life.

He refers to unnamed and named purported experts in the field (1):

Russian investigators in particular questioned the biogenic origin of oil, suggesting that hydrocarbons were a natural constituent of the earth’s interior in no way related to surface life. Thomas Gold (1920-2004) championed the abiogenic theory here in America and was instrumental in the disposing of the myth that oil is a fossil fuel.

He then mentions, but does not refer to, some experiments:

Furthermore, experiments by Gold and others have verified that hydrocarbons can be generated from non organic sources under the conditions that must prevail deep in the earth.

Naturally, no analysis or even brief mention of how this experiment was carried out is mentioned, nor any detail whatsoever on where this experiment was published. He offers a challenge:

I join with others by offering the following challenge. Demonstrate in the experimental laboratory how reptile flesh can be converted into crude oil.

Without waiting for the response to his challenge, he declares victory:

Once again we see the persistence of a transparent myth in the face of incontrovertible, scientifically derived evidence to the contrary.

He wouldn't be Davison if he didn't conclude with tying this to that hated Darwinism somehow:

Fossil fuel, Darwinian evolution and Free Will are all myths and all for exactly the same reason.

And ends by quoting a famous scientist, because citations of opinions are more important than references to data:

“Facts which at first seem improbable will, on scant explanation, drop the cloak which has hidden them and stand forth in naked and simple beauty.”

Naturally without any reference to where this quote is from, but then again, no such reference is needed, for the very fact that Galileo is claimed to have said that -- and he may very well have done so -- is in itself evidence that Davison's analysis is correct, even if the quote as such is entirely irrelevant to the original claim.

It is important to keep in mind that the god-based front-loading ideas of Davison are all structured in the same way -- assertion, appeal to opinions of or quotes from old scientists taken out of context, declaration of victory -- and this is the explanation for the diversity of nature that randman prefers, because there is, according to him, just no evidence for evolutionary theory (= "mainstream evo practices").

Again, I can really recommend reading Davison. He's hilarious.

---
(1) Remarkably for a creat-- critic of mainstream evo practices, he is fully in support of a champion for something called "abiogenesis".
 
Furthermore, experiments by Gold and others have verified that hydrocarbons can be generated from non organic sources under the conditions that must prevail deep in the earth.

Whoa whoa whoa... WHAT?! Does this guy wear his pants on his head?
 
Already answered you, Kot, with Darwin's response to him saying he couldn't agree with his views, and the less reliable wiki article.

Sad that'd you continue to lie.
 
Kot, already answered you on the functional and non-functional DNA issue. Sad you cannot understand it but it's not my fault. Please pay attention to the specifics of the argument. Evos said repetitions of non-functional DNA were stronger evidence for evolution because they could not be there due to functional design as creationists and IDers argued. In other words, though they also said functional DNA was evidence for evolution, they argued non-functional homologous sequences were PARTICULAR evidence for evolution and did so for years and years vehemently, even saying that piece of evidence alone was a slam dunk essentially.

IDers predicted science would show so-called junk DNA was functional.

IDers were right. Evos were wrong.

Deal with it.
 
So can any evolutionist explain how the hour-glass model would, if even true, be evidence for evolution, or are all of you going to continue to dodge the question?
