you ignored the relevant fact, which you admit to. i admitted and ignored the fact? or i admitted to ignoring the fact? what?
Pakicetus is not really a whale, is he? define "whale." the thing that creationists have a hard time wrapping their head around is that there really aren't clear lines of what's what sometimes. in this case, it's not exactly a whale, but it's not exactly a terrestrial ungulate either. that's what a transitional species is: something that is in transition between two groups. calling it a whale may or may not be "just for effect" but the point is that it's not a LIE. it can be defined as a whale, depending on where you draw the line -- currently, the scientific community draws the line AT pakicetus: everything afterward are whales, everything before are even-toed ungulates.
What completely goes beyond you is that such overstatements "for effect" are no sober, reasoned, objective analysis and have no place in science education and presentation. mind if i quote on that in the nde thread?
You think it's OK for scientists to do this in advancing evolution because the goal is to get people to believe it. strawman. i don't think deception is ok -- ever. the problem is that you think there is deception going on, because, frankly, you don't know the first thing about paleontology or biology. it's obvious that you're taking issue with the drawings because you refuse to even try to comprehend the more academic arguments.
I think the goal is to teach people to objectively be able to assess the data in a scientific manner for themselves, and so it's not OK. and part of that objectivity is common sense -- the thing that tells us that drawings do not always equal statements of fact.
It's all about whether one favors education or indoctrination. clearly creationism is not guilty of indoctrination. if you're REALLY interested in education, how about you read the article?

This can be corrected by a biologist who actually understands the details. I'm willing to bet that it was called a whale because it IS a cetacean. Since most of the general public would go "huh" at cetacean but many living cetaceans are whales that is the word used. It could have been dophin as well I suppose but whale is the best colloquial term available.
In the way that the man-on-the-street understands the term Pakicetus was a whale.

I don't see people advocating ID making overstated evidentiary claims. That's the difference. may i suggest a book? "darwin's black box: the biochemical challenge to evolution" by michael behe.
The goal for science should not be to get people to believe evolution or ID, but to teach them how to think in a manner in which they can judge for themselves if one theory is right or another. not to mention the difference between hard science, pseudoscience, and art.
Unfortunately, evolutionists do not teach that way in respect to evolution, but teach the theory via methods of indoctrination, often teaching evidentiary claims that are overstated and incorrect, but which have the result of making their case more convincing. *yawn*

First, I think the claims being based only on a skull are oversatements. You can't do a good job of recreating what the creature may have looked like with the skull alone. you're right, randman, you can't. that's why when it says "known only from a skull" most people read it as meaning the reconstruction is hypothetical. however, they weren't just making stuff up -- the drew from other known animals with similar skulls, such as ambulocetus.
I've got no problem with adding in artistic license if you have a larger specimen, but what we had here was "just a skull", and they added excessive whale-like features, such as showing webbed feet instead of hooves. i'm sorry, i don't know of any whales with webbed feet.
Those whale-like features that did not exist have the effect of making the case for it being an ancestral whale more plausible and believable. no, no, no. the case for it being an ancestral whale is in the actual preserved anatomy: the bones. not the drawing -- the drawing is JUST A DRAWING. they made it look a lot like a whale because from what they knew it was related to whales. and for god's sake, you don't know what soft features it had and what soft features it didn't have. there is not a lot of way to tell without footprints or a mummified corpse.
I don't think presenting far-fetched guesses based on only one skull is "honest." it's not far-fetched. it's a guess based on similar known species. see, you don't know how little they were guessing. you think that abscence of a skeleton means that we're msising a lot of information: actually, you can tell what kind of animal something was from far more miniscule bones. in this case, we knew it fed primarily on fish, was related to whales, was not fully aquatic. we could guess on the body type fairly reliably based other such animals. and it says it's a guess. what more do you want, randman? your logic could be used to attack ANY reconstruction -- in the abscence of information, how do we know it had external ears and fur, and whisker? hmm? explain to me why you think guessing is ok in one way, but not in another? your favored illustration looks almost exactly like the one you were complaining about. did you notice that? or were you ignoring that post too?

Arach, I'm not wasting my time with your excessively long posts if after the first line or so, you don't address my points properly. So large CAPS just get glossed over.
Of course, I recognize as I think everyone does, that you have no interest in real discussion here, but post to lurkers and so after you cannot answer a point, resort to large CAPS, misleading points, diagrams, etc,... I think a smart lurker can see through your methodology, but maybe some do not.

Arach, I'm not wasting my time no, i'm wasting my time here.
you don't address my points properly you still haven't addressed my very first post in this thread.
Of course, I recognize as I think everyone does, that you have no interest in real discussion here, but post to lurkers and so after you cannot answer a point, resort to large CAPS, misleading points, diagrams, etc,... what point can't i answer? i've answered every point you've ever had in this thread. so far, you haven't answered, off the top of my head:
obviously you're not interested in real discussion. you just keep posting the same crap about how there's some big evo conspiracy to indoctrinate our youth, and how they keep lying with drawings like haeckel did, and how clearly they were jumping to conclusions.
I think a smart lurker can see through your methodology, but maybe some do not. i think a severely mentally handicapped lurker can see through yours:
basically: claim, avoid, slander, repeat. how is this honest? This message has been edited by arachnophilia, 12-02-2005 03:07 AM

With all due respect, I have made it clear that I think this is important primarily because of the way such false depictions affect the public. So non-technical journals are the primary evidence here, and their depictions. This is in the Education forum, right? Yes false depictions are a problem. For instance it is obvious why creationists believe that humans and dinosuars coexisted when you see images like this:

I don't see people advocating ID making overstated evidentiary claims. That's the difference. randmand nde thread, msg 1 writes: Imo, the study published in the Lancet scientifically confirms that consciousness exists outside of the brain and after death. The fact people can remember what happened when their brain is inactive and they are dead is proof positive of this. Quite.

randman writes: Arach in a typically asine manner...That's deception on his part...... If you guys had some character about you... Please argue the topic and not the person. My sense is that you're failing to make your case because you believe you needn't go to the effort of building an effective and cohesive argument because the duplicity of evolutionists is self-evident. This causes you to repeat old arguments fairly frequently and to only rarely actually address your opponents. My advice to you, as it has been all along, is to focus on the topic and respond to what people say. Quoting what you're responding to would help others understand your rebuttal by placing it in context, and it would help keep you on topic since it would be there for you to review while you're typing.

randman writes: He subtly tries to claim I assert that the pictures are presented as evidence for technical journals, which I do not, but do mention they are included in peer-reviewed journals. But he's just trying to dodge and weave from the OP here. The point is the pictures are used to make a convincing case to the public via textbooks, magazines like National Geographic, etc,....and that's what the OP is discussing. I think everyone already understands you're trying to make the point that evolutionists tout false depictions in order to promote the fallacy of evolution. And the evolutionist position is that they are merely the best depictions that can be managed at the time to represent the understandings of evolutionary scientists based upon available evidence.
As we now know, the depiction of Pakicetus with webbed feet rather than hooves could not be realistically known from just parts of the skull; that the depiction was a gross overstatement of their case here.. I think if you took the time to read what people are telling you that you'd realize that such a conclusion is at best premature and at worst wrong. As I told you back in Message 178, Gingerich believes Pakicetus had webbed feet. I quote the same text I quoted before from his website (Philip D. Gingerich), and I include the artists conception paintings:
Gingerich writes: Based on what we know today, these animals were probably less different than shown here, and the hands and feet reconstructed for Pakicetus probably looked more like those now known for Rodhocetus. Pakicetus is on the left, Rodhocetus is on the right. Note that Rodhocetus has webbed rear feet, and partially webbed front feet. So Gingerich still endorses the original Pakicetus depiction, and still believes it had webbed feet. I inquired earlier about how this depiction relates to the earliest one for Pakicetus: This appears to be a clawed, not hooved, creature. Jar compares it to the difference between an otter in and out of water, but I've seen otters out of water, too, and I don't see it that way. If you look at an otter and an otter skeleton, you can see a resemblance:
But I see little resemblence here, and no one has explained how Gingerich could still endorse the original depiction given what we now know about the skeleton:

randman writes: How about other hooved animals? Since Pakicetus had hooves, why is he not in line with other later creatures that had hooves? The reason is basically subjective; because evos want him to be ancestral to whales. In his reply to this in Message 238, Arachnophilia accepts the argument that Pakicetus had hooves, so I'm confused. Isn't this a Pakicetus skeleton:
The appendages on the end of the legs look like claws to me. --Percy

Hey Percy. Hooves aren't allways a "horse hoove"
Remember, paki is what is called an even toed ungulate. This includes piggs, hippoes, and other creatures. These are "hooved" animals in that their feet have that structure. Here is a little illustration showcasing different forms of ungulate feet (hooves):
For some more context, think of the early horse, eoehippus:

randman writes: You evos, it seems to me, take a different stance. It seems the goal is not education, but indoctrination. You want to convince people that a theory is true... There's a large industry out there that packages science into forms that laypeople can understand. And there's the textbook industry that packages current scientific views into a form students can understand. When the current understanding changes because of new data or improved insight you seem to be concluding the previous understanding was some sort of fraud, while ignoring the tentative nature of science, and also ignoring the history of science as one of gradually improving understanding. I think most here acknowledge the problem that textbook publishers tend to get locked into certain views and presentations that eventually become dated or misleading or wrong, but you'll find few defenders of the textbook industry here. My daughter took biology last year, and her textbook was a huge compendium of useful information but also of poorly explained and misexplained and misrepresented information. Scientists don't write the textbooks used in public schools, laypeople familiar with science do. The textbooks at the college level are much better because they tend to be written by professors who are engaged in actual research. But the public representations of biology in magazines and books and textbooks are no different in character and accuracy from any of the other branches of science. Biologists are no more engaged in a conspiracy to convince the public of a false theory than are physicists or cosmologists.
But it's not useful at all if you are trying to educate. In fact, it's completely wrong. It sends the wrong message, and moreover it passes off falsehoods as reasonable. You won't find many to agree with you that the best conclusions drawn from available evidence are falsehoods. --Percy

RAZD writes: Because it shows a semi-aquatic\terrestrial animal surface diving to catch fish? I don't think so. But Arachnophilia's interpretation seems to be that when Ginerich says "these animals were less different", he means that Pakicetus was much closer in appearance to Rodhocetus, and looking at the long legs of Rochocetus you can see that it does bear a very close resemblance to the Pakicetus skeleton. Here are all those pics:
So I guess Arachnophilia has convinced me that Gingerich *is* admitting the original depiction is no longer accurate, but he sure isn't doing it in any overt way. For context, here's Gingrich's coments on the paintings (not the skeleton) from his website:
Figure 13.Artists' restorations of Pakicetus inachus (left) and Rodhocetus balochistanensis (right), as featured on the cover of Science. These accompanied articles by Gingerich et al. (1983) and Gingerich et al. (2001). The Pakicetus cover was painted by Karen Klitz of the University of Michigan Museum of Paleontology (now at U. C. Berkeley), and the Rodhocetus cover was drawn by John Klausmeyer of the University of Michigan Exhibit Museum. Based on what we know today, these animals were probably less different than shown here, and the hands and feet reconstructed for Pakicetus probably looked more like those now known for Rodhocetus. Covers ©American Association for the Advancement of Science. Given that he gets into enough detail to mention the hands and feet, I don't he's basing it on superficial similarities. --Percy This message has been edited by Percy, 12-02-2005 10:05 AM
