randman switcharound
the simple answer could also be that dinosaurs lived, but not in sufficient numbers and not in that specific locale.
I'm sure you were denying this kind of argument had any merit when asking why we don't see certain whale fossils at certain locales...
I know that has a great potential to swing this off topic so let's not go down that that route. But as Yaro said, Dinos seem to be relatively well represented in that locale, but not in the tar pits.

Re: randman switcharound
Hmmm....so are you claiming that if we don't see whales at locations, then they didn't exist during that era?
I believe that was the crux of your argument. Ours was, to paraphrase your Message 33:
paraphrasing randman writes:
the simple answer could also be whale transitionals lived, but not in sufficient numbers and not in that specific locale.
Hence why I said what I just said in Message 47

Re: randman switcharound
I'm sorry, my Message 50 was terribly obfuscated. If you aren't able to untangle the webs of wit and powerful rhetoric, let me help you:
are you claiming that if we don't see whales at locations, then they didn't exist during that era?
No - that's a closer description of what you were trying to claim.


I hope you aren't trying to take up the next 10 pages of this thread with this.

Re: randman switcharound
You are trying to have it both ways here, and that's wrong Modulous. Take a stand, please.
I answered your question,
randman's question writes:
so are you claiming that if we don't see whales at locations, then they didn't exist during that era?
with an obvious 'No' in Message 50 and a direct, blatant and explicit 'No' in Message 55. How am I not taking a stand, randman?
Btw, I guess it went right over your head the fact that in the whale examples we were discussing creatures presently in abundance whereas with the dinos we were theorizing if any species could have survived.
But it seems you have to people spell out the very obvious. We had an abundance of A (Basilosaurus for example) and then an abundance of, say, Z, but we see nothing of the species in between.
With dinos, we don't see an abundance of Z.
I can only hope you are able to grasp the difference. Can you?
Not at all, I agree that the two situations are different. In the whale scenario we do not know if our inbetween species existed in that locale or if they existed in significant numbers. In the dino example we know that dinos existed at that locale and in significant numbers. Entirely different.

Re: randman switcharound
What a mass of confused thinking! So dinos existed during the time of the La Brea tar pits, but we just cannot find their bones, eh?
No randman, read it again. The statement I made, once again for you was
In the dino example we know that dinos existed at that locale and in significant numbers.
Since we don't see them in the tar pits we can conclude that they were not contempory with the tar pits.

Re: randman switcharound
But modulous here wants to turn that around, and claims it is reasonable to see whales and their ancestors in abundance all over the world, but not to see the species in between in the same places.
Well, I don't want to turn this into a whale debate so let me actually clarify for you what I am actually claiming.
I am claiming that you rejected the following argument
'We don't see organism x in the fossil record because it didn't exist at locales y in significant numbers'
on the grounds that they must have existed in significant numbers in that locale. There is no evidence that they did, but you asserted that they must.
and you are now using the argument
'We don't see organisms x in the tar pit because it might not have existed at locale y in significant numbers'
even though there is evidence that organisms x did exist in that locale in significant numbers.

Time and space
Dinos were declining and/or extinct. So they wouldn't exist at those locales. Right?
The problem we are having is a time/space issue. Dinosaurs did exist in that area, just not at the time of the tar pit.
Wha[le] ancestors were abundant at certain locales and so were whales.
Agreed, and at different times.
So the declining argument does not hold true.
Right, all we know is that whale ancestors and whales existed at those locales in significant numbers.
So as argued with the La Brea tar pits, the absence of a certain species is evidence they did not exist. Right?
It is evidence that they probably didn't exist at that place in that time in significant figures. Especially given the abundance and variety of organisms that were found in the pits.
But oh no, evos cannot argue that, can they?
That's the argument being put forward by this very thread.
So which is it?
Simple:
If we know that dinosaurs existed in that area at one time, but they didn't get preserved in a tar pit which preserved a large amount then it is probably they didn't exist at the same time as the tar pit.
We do not know that some of the transitional whales existed in a certain area in signifant numbers, so we cannot say if we should expect them to have been preserved by fossilization (and then survive/be found etc).
If we don't see the fossils does that mean they weren't there
Bingo! Or that they were there in small numbers.
or it that they just didn't fossilize there OR ANYWHERE FOR THAT MATTER!
YES! Once again, this is another possibility.
I can't help it if you guys equate a declining population heading into extinction with an evolving one, supposedly, but I will try.
Nobody is making that equation. I even said:
quote:
the two situations are different
in Message 57
At say point 1 in time and evolutionary development, there is an estimate of X million members of various species. At the same locales, at point 10,000, we see similar large numbers of various members of species evos claim evolved from point 1. There is not a declining number here as with the dino example.
right, the two situations are different.
In the dino example, the dinos are either extinct or severely declined in population.
Correct!

Re: Time and space
That's where you are wrong.
OK, great, let's explore this - Percy has given us the go ahead. If Yaro wants to veto the discussion, I'll start another topic and we can discuss the tar exclusively.
We do see Basilosaurus for example in large numbers
Yes, OK, we have evidence that Basilosaurus existed in those areas in significant numbers.
we see whales in large numbers
OK, we have evidence that modern whales existed in those areas.
we don't see the in-between species
OK, so we don't have any evidence that these in-between species existed in these areas in significant numbers.
That a distant ancestor and the modern animal exists in the area is not evidence that the in-between species existed there as well. Actually, if a population was to become isolated it would probably start that by being located in a geographically dissimilar place than its parent population, so it would be quite unusual to see all the transitions in the same area.
I think that is what I was saying when I said:
We do not know that some of the transitional whales existed in a certain area in signifant numbers
You are merely guessing that they were there, with no evidence to support that.
You say, well, we don't see dinosaurs in the tar pits so they probably were not alive then
Yes, and I believe that you say that too.
but the fact we don't see the transitionals is to you evidence not that did not exist, but evidence in some twisted fashion that they must have existed anyway.
Let's go over this again:
  1. Dinosaurs were abundant in area x at time a
  2. Lots of organisms were preserved in tar at area x at time b
  3. Not one dinosaur was preserved in tar at area x
    Conclusion: Dinosaurs were not abundant in area x at time b
  4. Lots of Basilosaurus were preserved as fossils in areas 1
  5. Only about 8 whale transitions have been found from the start of basilosaurus to modern whales, in small numbers in areas 1
    Conclusion: Either whale transitionals were not abundant in areas 1 or they existed in those areas at a time when those areas were not conducive to fossilization and long time preservation.
I'm not having it 'both ways'. I'm applying the same argument both times.
Once we agree here, we need to agree that a tar pit is an area very conducive to preservation. Then we are close to finally coming to full agreement, so let's see how far we get.

Re: randman switcharound
Wrong. I never asserted dinos existed at that locale at all, period.
Let me repost what I wrote:
quote:

'We don't see organisms x in the tar pit because it might not have existed at locale y in significant numbers'
even though there is evidence that organisms x did exist in that locale in significant numbers.
You rejected it when you said:

In Message 33

No you didn't. Nor did I say you did. I said that you are using the argument 'even though there is evidence that organisms x did exist in that locale in significant numbers'

Irrelevant
That's wrong. You need to spend time studying the list of 8 you gave and really dig into the research. Listing dolphins as transitional with whales when we have dolphins today is wrong, and evo twisting of the dates to fit their models is wrong
Rather than go into this, how about you actually address the point?
There are not 8 whale transitions between Basilosaurus and modern whales.
I really don't care to go into this. It makes no difference to the point of my post. If you wish you can replace that statement without the mention of 8 transitionals. Maybe some other time we can talk about these 8 fellas?
More educated evos have begun to recognize this which is one reason they no longer claim Basilosaurus as an ancestor to whales.
Is this relevant? Please address the actual post, thanks.

Fossilization vs Tar preservation
Modulous, I will try once again. If dinos had died off or were declining, one would not expect to see them, right?
Agreed.
You have Xbillion members declining to either 0 or maybe Xmillion members. That is a declining scale. That does not mean that they do not exist. That is my point.
I agree. Haven't disagreed with this point. I believe I said:
quote:
Conclusion: Dinosaurs were not abundant in area x at time b
But considering whale ancestors, supposedly and whales, we have presumably a more constant, Xbillion.
That's a fairly large presumption isn't it? But let's go with this, see where its going...
So since there is no decline, we should expect to see this group well-represented at all points in aquatic environments.
Unless of course that at the areas which have fossils surviving, these organisms didn't exist in significant numbers, or their fossils did not survive, or the area became temorarily unconducive to fossilization, or...
So there is no excuse to claim thousands of species existed in the "tar pits" of aquatic environment without any evidence they existed.
Well, I started to address this in Message 71. Perhaps you can go back to it and address the points (tell me where you agree and disagree and why as I have been doing with your posts). If, after addressing that post, you feel there are other issues that need raising, then we'll get to them, OK?

Re: Fossilization vs Tar preservation
That could be a possibility if there was some way for the transitional species to occupy a different habitat other than aquatic, but unless you are claiming they could have evolved back onto land and then back to the water, it is a moot point.
Excellent, you accept that it is a possibility, if the transitional species was to occupy a different 'habitat'. We're close to agreeing, I can almost feel it.
'Aquatic' is not an area. If basilosaurus existed in area 1, and some of the population drifted to area 2. The populations may stop breeding, speciate and go on to form some of our transitionals.
So far so good. Now what if area 2 was rubbish for fossilization? What if it was an area whose fossils did not survive to our age? What if all the other things we've discussed? Then we wouldn't find their fossils would we?


Any chance of going back to Message 71 and actually addressing it?

Re: Time and space
Please actually address the post by telling me where we agree and disagree. That would really help this discussion move forward, I feel. The points you raise here are identical to the points you raised in Message 82. Why did you raise the same points to me twice in a row?
Anyway, for the readers, I dealt with this in Message 87
