Re: Webbed/not webbed - Who cares, why not talk about the "hard parts" evidence
most of us recognize that drawings and paintings like these are not hard scientific fact. they are subject to the artist's own interpretation, creativity, whims, and expression. they are personalized, not standardized.
Not only that, it's the front cover of a magazine not an illustration in an actual article. I would suggest that the main point of the picture is to get the attention of people. You've got to make owning and reading the magazine interesting and a pleasant experience if you want folks to maintain their subscriptions or pick it up at a newstand or in the airport.
I think it's been pointed out before but if you read the 1983 article in Science it specifically says:
The dentition and cranial anatomy of Pakicetus indicate that it was well equipped to feed on fishes in the surface waters of shallow seas, but it lacked auditory adaptations necessary for a fully marine existence. We do not yet know anything about the postcranial anatomy of early Eocence whales. The fact that Pakicetus is preserved in fulvial red sediments in association with land mammals indicate that early Eocence whales may still have spent a significant amount of time on land. Evidence suggests that Pakicetus and other early Eocene cetaceans represent an amphibious stage in the gradual evolutionary transition of primitive whales from land to sea.
Note: I had to type this in manually as the link is to a scanned image, so any typos are my fault.
So right from virtually the earliest days (I think Pakicetus was first described in 1981 by Gingerich) it's been pointed out:
lacked auditory adaptations necessary for a fully marine existence
We do not yet know anything about the postcranial anatomy of early Eocence whales
in association with land mammals
may still have spent a significant amount of time on land
Evidence suggests that Pakicetus and other early Eocene cetaceans represent an amphibious stage in the gradual evolutionary transition of primitive whales from land to sea
Seems to me that even with just the original partial skull and teeth finds Gingerich got pretty close to the mark. Not to mention that there is no deception, no asserting things he can't back up as facts or any of the other things randman claims.
In fact the subsequent body part finds line up surprisingly well IMO (well perhaps not too surprising when you think that it is his job after all).

I wish I didn't know now what I didn't know then

No problem - now if we could only get randman to read what it actually says

Re: Webbed/not webbed - Who cares, why not talk about the "hard parts" evidence
My point is the average person reading this
But in at least the case of the 1983 Science article you clearly didn't read it. You're fixated on the front cover illustration which, as I and others have mentioned, is not part of the hard science - it's to help sell the magazine as much as anything.
In my Message 160 I quoted a few bits from the actual article:
lacked auditory adaptations necessary for a fully marine existence
We do not yet know anything about the postcranial anatomy of early Eocence whales
in association with land mammals
may still have spent a significant amount of time on land
Evidence suggests that Pakicetus and other early Eocene cetaceans represent an amphibious stage in the gradual evolutionary transition of primitive whales from land to sea
Damn those evil evo scientists - always misleading everyone by drawing conclusions based on the best currently available evidence.

Re: Respond to what?
that it's perfectly reasonable to claim Pakicetus swam around diving deep like a whale
Where was this claimed?
Not in the 1983 Science article as far as I recall or even on the front cover illustration. That shows Pakicetus diving certainly, but not much deeper than its own body length (if even that).

I wish I didn't know now what I didn't know then

Re: Respond to what?
You still haven't read the article have you?
He's diving well beneath his body length chasing fish with his mouth open. Yea, it's not as deep as whales can go obviously,
I strongly contest the view it's "well beneath his body length" - the spine is curved quite a lot so I contend if you were to straighten the spine and put it vertical it would be somewhere around the actual body length.
But you specifically claimed
diving deep like a whale
but that illustration shows it diving to less than the same depth (relative to body size) that a human can easily manage - let alone something like an otter. How deep do you think 'deep diving' is for a whale?
Looks like the evos aren't the only ones who can be charged with making exaggerated claims eh?
but rather than showing him as a hooved animal running at high speeds over land, they show him behaving like a whale, with a large, blubbery-looking exterior, diving and chasing fish underwater.
You still haven't read the article have you? I quote:
We do not yet know anything about the postcranial anatomy of early Eocence whales
The front cover illustration is not that closely related to the actual science - it's just not that important.
If you can't see that as grossly inaccurate and misleading,
No I don't - not with the information available at the time
I don't think reason will work with you.
Ha ha ha ha ha ha ha! Oh the irony
Let me put it this way, a better pic would be more similar to showing a gazelle running than some sort of whale/land mammal hybrid.
You still haven't read the article have you?
A gazelle!? Look at the teeth described in the article and tell me you still think a gazelle would be a good basis for a picture.

Re: Respond to what?
I already said not as deep as a whale, and that was a mistatement, and clarified my point that it showed the creature behaving like a whale, diving down, mouth open, chasing schools of fish with a blubbery, whale-like exteriour.
Or like a semi-aquatic mammal perhaps.
Actually - and I can't be dogmatic about this - but to the best of my recollection from various nature programs I've seen over the years modern ceteceans don't necessarily surface dive and catch shallow water fish. They spend extended periods underwater hunting for fish and catch them from below and at the same level as much as from above.
By the way, how do you think any animal is going to catch fish underwater with their mouth closed? No smart-arse answers about bird claws
The fact you see nothing wrong with such a description pretty much proves my point about evos.
In 1983 - when all they had were partial skulls - I don't see anything wrong with it, no.

I wish I didn't know now what I didn't know then

Re: Wrong.
How do you explain calling this a whale?
Read the 1983 article and you'll know the answer to that one.
