Even if the moths were glued to the trees by research assistants it doesn't change the fact that the environment of the moths selects for certain pigmentation. Staging a photograph to help illustrate that is not misleading.
Can you explain in some more detail. Is the above what happened? That is, did they simply "tie down" the moths in a place that they were naturally a lot of the time just to allow for taking a picture. To me this would really be something that doesn't affect anything. Or is there more to the fruhaha?

Thank you. That is a useful expostion of the whole story. Another lie or near lie by some of the creationist sites. Tch tch.

and speciation seems to be accepted by many if not most creationists. In fact others accept the evolution of new genera as well. Not only that but they accept an enormous rate of evolution to boot.
I still haven't figured out what the story is. There seems to be some different variation for every individual creationist. And sometimes several stories from one individual which contradict each other.
Members should, maybe, have a bunch of check boxes on their profile at sign up.
Eg.,
Age of earth
a) 6,000 years,
b)under 10,000 and over 6,000,
c)anything up to 30,000,
d)4.5 billion years or so
Evolution
a)none at all,
b)variations within kinds (kind = species)
c)kind = genera,
d)kind = family (but not for humans)
e) everything evolved but not humans
f) everyting evolved including humans but some steps were magic (ID)
e)none of the above
The flood
a)it rained a lot,
b)the earth was torn apart by catastrophes of all kinds,
c)the tide came in big time AND it rained a lot
d)a bunch of things happened which I wil add to in an adhoc fashion

Misleading
In spite of all the various disclaimers and the long history of carelessness with those dammed drawings I still think it is misleading to reproduce them.
If one disclaimers the hell out of them but still shows drawings that are more similar to each other than is justifiable that is misleading and, to some degree, dishonest.
However, what isn't clear is how "fudged" the drawings are. I am agreeing that they are becase many experts say they were. When I look at them and the posted pictures I see only a little fudge and not enough to invalidate the overall picture. There is, as noted elsewhere, some "fudge" in all drawings. That is part of the reason for doing them; To clarify something.

adding on of traits?
Well, the details that Haekel was propounding were wrong. But the prediction from common descent did hold true.
I'd like from you to know just what is wrong with the drawings and just what prediction is not true.

pharygeal pouchs
They may be called gill pouches, but they certainly are not gill pouches. Calling something that it isn't is called not telling the truth.

So, what we have here is multiple lines of evidencelocation, function, several molecular markers, and developmental origins and processesthat converge to show that parathyroid glands and the gills of fishes have a common evolutionary origin.

Re: pharygeal pouchs
Now, as far as the details on the parathyroid being related to gills, I would need to see more details than mere claims, especially in area where in the past evolutionists have made claims, and still do sometimes, which have been proven false and at times just unproven.
What details do you need? Exactly which claims do you believe are false? What reasons do you have to believe they are false?
As far as molecular markers, what other "markers" exist in the parathyroid? Where is the peer-reviewed discussion of this? Finding one genetic marker hardly seems like a definitive argument. Maybe the gene is involved in any organ related to salt regulation, or related to salt regulation?
So you agree that there are markers connecting them? How many do you need to be convinced? On what basis do you believe that what you have isn't enough to be strongly indicative if not definitive? Why isn't it reasonably definitive in light of the other data?
None of the arguments in that article are persuasive, and neither are of such a comprehensive nature as to commend the article.
Why not?
Do you disagree with the development shown from the 5 week old embryo? Why? Why isn't this useful information for coming to a tentative conclusion?
For example, have any of these claims been criticized, and if so, what are the arguments of the critics and how are they wrong? I didn't notice that, and in general it just is a very weak argument and presentation once you look into the details a bit more.
I don't know? Can't you find any criticisms? I think it is your turn to do so. This is an example of information that makes your claims seem to be a bit unfounded. Do you have arguments against it at the same level of detail?
Note too the claims of functional similarity are bogus since they are not functional similar since one is more or less a filter and another a production center.
Has WK's post Message 245 answered this point for you? If not why not?

pharnygeal pouchs common design?
On WK's post, he did a good job showing that there was an overstatement on the part of the creationist web-site, but there are still some significant differences in function. Personally, either convergent evolution or just a common designer working from a common design are plausible explanations for such similarities.
Of what relevance is this? We are discussing whether or not there are pharyngeal pouchs? They may have arisen through evolutionary processes (either common descent or convergence) or common design. The discussion is whether or not the embryos of various species show development of structures that have some relationship to each other.
Secondly, I would want to see all the potential "markers", in other words, comprehensive comparisons of all of the genes related in any way to the parathyroid function and to gills, but also to other organs and other species so we could properly see the significance of this.
In other words to convince you it will take more information than is currently available. No problem, that is up to you. However, this is enough to convince me that there is a reasonable possibility (if not definitive) that it is not fraudulent to talk about the connections between embryos of different species and that is all that is being discussed here.
In other words, your claim of unfounded, fraudulent assertions is wrong.
One marker hardly seems definitive, and I am not sure what "other data" you refer to. Function is not identical. Location is a weak argument. Convergent evolution or common design could also explain the marker.
Perhaps you should reread the article. Again, the way they get there isn't material to whether or not there is fraud. You seem to be suggesting that common design is the explanation for the relationships we see between embryonic structures. If there is any relationship for any reason then the claims we are discussing are not unfounded or fraudulant. They interpretation of them may be incorrect if your common design interpretation is right but that is a separate issue.
It just seems more like a stretch to me from very little evidence.
The evidence is there to show that this is not a fraudulant suggestion. And the 'very little' is more evidence than you have for your suggestion of how it came about.

What is the discussion about?
1. The use of Haeckel's drawings to depict various versions of recapitulation.
2. Asserting humans have gill slits, gill pouches, etc,..
3. Claiming a phylotypic stage as evidence prior to that being proven.
1. We agreed that Haeckel faked it way back at the beginning of the discussion.
2. There is good evidence that human structures are, in some way, related to gills in the developement of embryos. Therefore not a fraud even if you think it is a misinterpretation.
3. "proven"? The stage seemed to be there from looking at gross anatomy (not proven) but indicative. Since then other things have come to light which supports that. What is "proven"? No one waits for 100% proof before putting forward suggested explanations.

Re: What is the discussion about?
Ned, to your credit, you agreed. Very few others agreed. Most persisted in defending the use of Haeckel's drawings in one form or another. I noticed you didn't jump in and reassert the fact they were totally unreasonable in doing so, and the same thing occurred with the defense of the claims of gill slits and gill pouches, one even arguing that "gill pouches" was acceptable because that's what they are called.
Well, I remember several agreeing that Haeckel faked it. Not a big deal; certainly not what you are making it out to be.
The use of drawings arranged like Haeckel's has, in my opinion, been shown to be perfectly reasonable. The embryo's of various species do have similarities and do undergo transformations that follow a similar pattern. In fact, evidence has been shown that these similarities are much more than just "skin deep". The developement of parts of humans from the same structures that give rise to gills has been shown. This is what makes the terms used acceptable.
The community uses them because they show an actual fact about embryonic development and should continue to do so. However, calling it the "evolutionist" community is a bit silly since it is really only very minorly involved with evolution but more with embryology.
The community has published comments on Haeckel's fraud. In fact, the first I ever heard about or saw drawings of that type was in an article discussing the issue and showing that they were faked.
That's sad, but hey, if you guys want to fall back on bashing creationism, religion, IDers, or whoever, that's your perogative.
What is sad is the creationist community misrepresenting the facts of the case and continuing to beat a dead horse. The use of drawings comparing the actual development of embryos in the way that Haeckel did (but without messing with them) is perfectly acceptable and shows facts of the development of them that you may not accept but that you have given nothing to suggest is wrong. You even decided that the explanation was either convergent evolution or ID seemingly accepting that there IS in fact a relationship between embryos to be explained by one of those two suggestions of yours. Of course, while you don't think the common descent explanation of the facts is adequately supported you have not yet offered any support for your two alternative explanations.

What year?
What year was that?
And what year did you first see or hear of embryonic evidence taught from Haeckel's drawings?
Dammed if I remember. More than a decade ago, probably less than 20 years and that was, as I said above, the first time I had heard of embryonic evidence being used. But then I've not had undergraduate level biology; I'm an interested amateur reader.

Re: What is the discussion about?
Ned, actual photos of species at similar levels of development strongly contradict Haeckel's claims, and the drawings based on his drawings were thus extremely fraudulent since they showed a non-existent similarity.
Haeckel's claims are not interesting since they have been known to be wrong for many decades.
Can you show actual similarity via photos and other evidence that indicate embryos are more similar in the ways evolutionists proposed, a phylotypic stage, or even just that they are more similar via common descent than a theorized convergent evolution of similarities?
This is exactly what the paper I referenced was talking about. It shows in detail. There are common origins for very dissimilar structures.
YOu comment about convergent evolution instead of common descent is, as I said above, nothing to do with this thread. The claim of fact of the relationships between embryonic development is what you have been calling fraud. You know are offering an alternative explanation for those observations that you have been calling fraud. This is confused and confusing.
I asked for the evidence, and none was given. I was not, as you claim, suggesting that convergent evolution or even ID was a fact. That's wrong, and I am frankly surprised you would say that.
I never claimed you said CE or ID was a fact. It was what I read you offering as an explanation for the nature of the development of human structures from pharngyeal arches. But we aren't (in this thread) interested in the explanation. We are interested in the nature of the development and how they compare across species.
But interestingly, when asked for comprehensive studies detailing evolutionist claims, I got none, nada.
You were given one reference to the development pathways and ignored ost of the evidence in it or brushed it off as CE or ID. However, by suggesting CE or ID you seem to suggest that the development pathways are actually as described. If they are, you claim that pointing this out is a repeat of Haeckel's fraud is refuted. That is these development pathways show that there IS at least some good reason .
pqs
Agreed there should be such similarities. We need to find such information. However, while we are at that can you comment on where we are right now?
Oh yeah, here is one study of a neck gland with a single genetic marker similar to gills, and hey, they both deal with salt regulation.
Big freaking deal! if that's what amounts to evidence, you guys have nothing basically. In fact, if the gene is required and occurs only with the function of salt regulation, then that's even less evidence than you guys claim because all that means is that there is a gene necessary for this function.
It is not just the marker. It is several pieces of data all pointing to the same thing. This appears that you are now denying that the connection is there. However, you have also offerered CE (Convergent evolution) and ID as possible explanations of the connection. Could you pick which view you hold please?
Does that mean the gene came from a mutual common ancestor?
It is not just the gene. You have not yet commented on the starting points for the various stuctures that come from the pharngyeal arches and where they end up. I see a strong similarity in the early stage (5 week) with the layout of other animals and then these structures end up in rather interesting places in humans. I don't remember your comment on this.
Nope. It could be. It could be that God puts this gene into any species with this function. It could be that the gene arose via convergent evolution.
So what? Are you now evoking ID as the explantion for a connection between species that you claimed it was fraudulent to say was there?

The drawings! NOT the conclusion
You say because of these similarities, that can only be explained by homologous ancestral structures.
I say, hogwash.
As you know I think they can be explained by shared ancestral stuctures. I am, however, as I have said several times before not arguing that here. What I have said is that there is evidence here of connections between these structures. That is using drawings that are laid out like (but not the same as) Haeckel's drawings is perfectly acceptable. The interpretation of what these structures mean is a separate issue.
It is not a fraud if the drawings are done correctly and show connections which are actutually there.
In the rest of your post you seem to agree that the connections are there. Therefore using correctly drawn diagrams of this type is perfectly acceptable. Therefore all the rest of your post is a non sequiter (if I can both spell that and have right what it means ).
In this post you now argue for a different explanation for the connections between embryos of different species. Fine for another topic. However, this topic is about whether these type of comparisons can be honestly put forward to support common descent.
While you may think they that there are other explanations do you not agree that they could just possibly support common descent as well? If not why not?

connections and explanations
I am not even sure what you mean by "connections."
randman writes:
I am not making a claim of ID, or convergent evolution. I am just pointing out that you cannot claim common ancestry when other explanations work just as well.
randman writes:
For example, you say the presence of this gene marker indicates common anscestry.
OK, but do we see similar situations of similar gene markers in similarities that arose via convergent evolution?
randman writes:
In other words, if we assume common descent, then the evidence can fit this way. If we assume a common designer, then the evidence can support that as well. It is not very definitive, imo.
I find you a bit confusing. Are you sure there aren't two different people using your ID?
If there are no connections what is your suggestion of convergent evolution or ID supposed to be explaining? Why exactly do you bring these concepts up in this thread at all?
