The Image in Question
Here is the image in question:
As you can see the illustration clearly points out that the creature in question is only known from a skull. This is done to hylight the tentativity of the depiction. None of the other illustrations bear this tag, and to anyone who reads the article it becomes clear why the illustration is done this way.
quote:
The skull belonged to a relatively small, furry, four-legged, meat-eater, one that walked on hooves and died around 50 million years ago. The fossil, named Pakicetus, was unearthed in the Himalayan foothills from sediments whose other contents tell us that the creature lived with land dwellers that included marsupials and our own very early ancestors, squirrl-size primates.
Its remains are closely linked with river channels, suggesting a life spent partly in the water. What causes scientists to declare the creature a whale? Subtle clues in combination - the arrangement of cusps on the molar teeth, a folding in a bone of the middle ear, and the positioning of the ear bones within the skull - are absent in other land mammals but signiature of late Eocene whales.
Note the emphasis. The creature was known to have hooves because of it's relationship with previous specimines (mesonychids), yet assumed to be partly aquatic like it's later ancestor ambulocetuc who's body was known, and was sort of built like a "hooved otter". Couple that with it's prevelance in ancient river beds, and you can deduce the creature may have been aquatic.
This is where the illustration comes from. Note the tentativity of the illustration, it is clearly pointed out in the article that they only have a skull and the illustration is based on what scientists thought the creature may have looked like.
But, and here is the most important bit that I do not want anyone to miss, so pay attention. The reason Paki is concidered a whale, has NOTHING TO DO WITH ITS BODY PLAN, it has EVERYTHING TO DO WITH ITS SKULL! That's it. That's what's important about the find.
Are we clear?

An example of ungulate feet
These are the feet of various ungulates. Showing how an ungulates feet can vary. The term "hoof" does not allways mean horse hoof.

A General Reply to Many Posts
On Aquatic vs. Semi-Aquatic:
I would like to point out that “semi-aquatic” does not necessarily mean that a creature has to look like an otter or a seal. Semi-aquatic creatures come in a variety of shapes and sizes. And BTW randman, humans are considered by some scientists to be semi-aquatic. Semi-aquatic simply means a creature who spends part of it's life on, in, near, and around water and another portion on land. It's a very broad term. As a result all of the following creatures are classified as Semi-Aquatic:
It is not an entirely unreasonable assumption that a creature is semi-aquatic when it lives so close to ancient river beds, is related to toothed whales, and it's immediate descendants are even more aquatic looking (Ambulocetus).
Ambulocetus:
On the Illustration:
As was pointed out randman, the article and the illustration make perfectly clear what the scientists know, what they think, and where they are coming from. There is no attempt at deception, they are simply presenting their “best-guess” as to what the creature looked like. You are being disingenuous, obviously you have not read the article yourself and are working solely from presupposition.
Let me put it to you this way, are forensic sketch artists lying when they draw up someones portrait based on bones? Are they lying when the sketch a criminal based on description?
How about this, where engineers and physicists lying when they described what they thought the future would look like?
This is from 1897:
Conclusion:
You are willfully ignoring the clear cut evidence contradicting your position. There is no deception going on. For some reason you seem to take a drawing (clearly labeled as tentative) as some sort of silver bullet. To be frank, you just don't know what you are talking about.

Re: ambulocetus
The article pointed out that ambulocetuses limbs are splayed out like those of an aquatic animal. I'll repost an image here:
Maybe I am wrong, but this is what I understood.

Re: ambulocetus
You were right however, I think I came off sounding like Paki evolved into Ambulo. That's not what happened of course, but the ambulocetus body-plan became a "forward trend"
Ambulo, BTW, shows up about a million years after Paki.

Re: The Image in Question
No, by the time the National Geographic article came out, they had more than the skull. National Geographic chose to show a false depiction totally inconsistent with the findings of science at that time.
Why?
Because they didn't know. I read the article and posted the image. The drawing was published after a skull.
It is somewhat incredible to me, by the way, that you cannot even acknowledge the illustrations were wrong, and they should have shown Pakicetus as a running land mammal since they had found more than the skull long before then and even interviewed the guy that found more fossilized remains of Pakicetus that argued that it was a land mammal, not aquatic.
Ya, it was wrong. No one disputes this. but it wasn't dishonest! That's the distinction.

Re: The Image in Question
OMG.... THE FACTS WEREN'T IN YET!!!!!
For chrisake! They didn't know yet... did you read the damn article? Did you? I have it infront of me.
The article says, they only have a skull. Get it?
Further, did you even bother to read the post above the last one.
ABE:
Randman, let's keep it simple.
Did they, or did they not, note that the drawing was only from a skull?

One Simple Question
I'll repost it here, just so you don't miss it.

Did national geographic note that the illustration was based on only a skull?

Publication Dates
National Geographic published it's article in Nov. 2001. This of course means that the magazine was on store shelves in Oct. 2001. If you know anything about publishing a major, mainstream, magazine, an issue may be anywhere from 3-6 months in production. Meaning that all items within would not be 100% uptodate (within a 3-6 month tolerance).
The first publication for the NEW pakicetus findings went out in Nature on september 20th:
quote:
Thewissen, J.G.M., Williams, E.M., Roe, L.J. and Hussain, S.T., Skeletons of terrestrial cetaceans and the relationship of whales to artiodactyls, Nature 413(6853):277-281, 20 September 2001.
So basicaly, National Geo. was wrapping production, issues were probably in the mail, and the news hadn't really gotten out into the mainstream yet. (After all, National Geo. is great, but it is mainstream ).

Re: One Simple Question
Except they had more than a skull.

WRONG!

At the time the article was written, all they had was a skull. Capice? Comprende?
So they presented a false depiction.

WRONG!

It was an incorrect depiction. The article made it clear. The illustration made it clear.
It matters not that they have the caption taken only from a skull because at that point, much more than a skull had been found.

WRONG!

The discovery was published Sep. 20th the Nov. issue is on store shelves, and in the mail in OCTOBRE. Further, big publications take 3-6 months to put together. I have worked in publishing, I know.
Lastly, the knowledge of the find was not yet mainstream. National Geo. didn't know about it yet.
They went with the description which just happens to exagerrate the creature that makes it appear more like the next creature in the so-called transition.

WRONG!

Again, at the time the article was written, all they had was a skull. The article makes it clear. As a matter of fact the writter is sitting down speaking with a scinetist while the skull in question is on the table.
just a coincidence, eh?
Your right randman. Its a conspiracy by evil scientists.

Re: Publication Dates
Pakicitus's full body findings were not made public till their apearance in science on Sept. 20th 2001. That's it. That's the fact.

Re: The Image in Question
pakicetus was first found in 1983, a skull. the article was published in 1998. the reconstruction you like was based on a more complete find in 2001.
Arach, the National Geographic article was published in 2001 also. It was the Nov. 2001 issue. The nature article came out Sep 20th 2001. National Geo. months are allways a month before the actual month meaning that the issue would have been on store shelves and in the mail during Octobre.
The fact is, the release of the new fossil findings was much too close to the National Geo publication. Not to mention the fact, that just because an article apears in Nature, it's not necisseraly the most mainstream info.
None the less, the article is very clearly written without knowledge of Pakicetus' body. Infact, the writter is sitting down with a scientist discussing the skull.

Re: comparison, round four -- BUMP
It's sad that you have degenerated in your posts to such low levels.
What is so low about the honest questions arach has posed? Can you really not see ANY similarity between the two skeletons?
Obviously, having discussed Neanderthals at some lengths on other threads, I recognize the differences. Unfortunately, neither you nor some others here see that there are much larger differences between the skeletons of Pakicestus and Ambiceletus or whatever it's name
BZZT! Stop right there. You can't just make a blanket statement like this. First of all, what do you consider "larger differences"? Do you not see the obvious similarity between the two creatures?
If so, why not assume relatedness? Why would two creatures look soooo alike, and not be related?
...than the 2 fully human skeletons you listed.
Other than the fact that one is not actually a homo sapiens.
In fact, your post is characteristic of the basic dishonesty and deception I have come to expect from you and evos in general. You present graphics in order to deceive rather than educate which is why you have no problem with falsely claiming Pakicetus had webbed feet and was aquatic.
First off, we don't know weather he did/didn't have webbed feet. Webbing doesn't fossilize, but how the hell can you say, with total certainty, that the creature didn't swim? After all, hippos spend most of their life in the water and they don't have webbed feet. All we have is bones! No one has unequivically stated he has webbed feat, an artists drawing is simply a guess and everyone freely admits that.
In fact, another here on this same thread engages in the same dishonest trickery, namely the use of graphics to try to reinforce false logic. The claim is because some animals can be excellent climbers or swimmers that somehow the depiction of webbed feet makes sense, but in reality, it is the exact opposite. There is no need to fabricate webbed feet because there is no reason for a land animal to need webbed feet to swim.
The point is valid. You are saying unequivically that paki didn't swim and had no webbed feet. They are showing you how an animal doesn't necisseraly need to "look" like a swimmer to be a good swimmer.
You are the one making statements based on knowledge you don't have. We have said over and over that the drawings and theories are based on evidince and therefore tentative.
It's clear that the depiction was designed to make the fully land animal appear more believable to the reader as an ancestor to whales.
The depiction was based on a skull. It was the best guess at the time. Do you understand that?
Look at the two skeletons, do you see how that guess could have been made?
You call that education because you beleive so strongly in the concept that it's OK to you if false data and statements are part of the argument since it illustrates what you think of as a true principle.
You have failed to show any deception. Continually asserting that scientists are liars is essentialy Ad Hominem. You should follow a different line of argumentation.
....
I saw Haeckel in your next paragraph so I knew it was a rabbit hole. Why not actually answer Arach's questions?
If you don't, you are being intellectually dishonest.
