Re: Put Up or Shut Up!

Percy, it is hard to be civil when, to me, there is a pattern of misrepresentation directed at me and other critics. For example, you suggest I think it miraculous that a species or subspecies could evolve in a small group. I have clearly never made such a claim. I would think you know that.
You remember the part of an earlier post where I said we're people just like you who aren't perfect? Well, guess what? I was right, I'm not perfect. Though I held the thought correctly in my mind, it was not correctly expressed when it reached my fingers. I understood what you said, and I intended to capture it accurately, but it somehow just didn't come out that way. What I should have said was, "You seem to think it rare, almost miraculous in fact, that many species would have a small population and limited range, but that is the case for most species alive today." I don't know how "many" became "a", I can't explain it.
What is it in your heart that sees evil and ill-intentions in every difference of opinion? Faith is the same way. Give it a break, will ya? We're just people, not evil conspiracists.
But the idea that a subspecies evolves, remains small, and this process repeats itself to such a degree that 99% of the time no larger forms ever emerge, is prepostrous. Neither you nor any evos have ever showed that this is likely. In fact, the idea that brand new forms would evolve, but never expand or branch out strains the imagination.
That's nice, but this is still an argument from personal incredulity, plus your list of possibilities is incomplete. For example, creatures from upland regions are almost never preserved as fossils, the conditions are not conducive to it. This provides huge regions that would have accommodated many large populations (and small, too, of course) over long periods of time with nothing whatsoever being recorded in the fossil record.
You seem to take as an imperative that the fossil record be complete, but it isn't an imperative. Not only is fossilization a dodgy kind of thing, erosion can wipe out millions and millions of years of fossil record (I forgot this one in my earlier list). Finding fossils is also a kind of spotty thing, since we can only find what happens to appear near the surface, in other words, what geological processes have happened to erode down to.
Now, presumably you guys claim before these whales and dolphins emerged, they had ancestors.
Ok, where are they?
I know this was a long, long time ago, oh, maybe an hour or two ago, but do you remember that list I presented? Twice? The one you claimed you had never seen before? Check out Message 147 for the most recent message where this list appears. Your question about "where are the transitionals" that you keep repeating has been addressed. Multiple times. Please respond to the points in this list. Oh, and if you could mentally include the point about layers with their fossils eroding away with the other items in the list I'd appreciate it. Thanks!
Think about this. Get past all the generalities and really think. The pattern should indicate that just before these whales and dolphins, there was something pretty similar occupying the same habitat, but whales and dolphins came along as a result of a subgroup evolving into whales and dolphins, and so the older forms disappeared.
But there was not necessarily something similar occupying the same habitat. Sometimes this will be the case, sometimes not, and how often which is the case you more often than not cannot ever find out. The habitat might not have existed before (plate tectonics, uplift and subsidence, environmental and climatic factors, etc.). The new species might arrive from a neighboring region. You're constructing a single scenario and then sticking with it as if it were the only possibility, and then your drawing conclusions that anything inconsistent with your favored scenario is impossible. But your scenario is only one of many. I couldn't even begin to list all the possibilites. There are more things in heaven and ocean, Randman, than are drempt of in your philosophy.
This is a pretty massive habitat. There is no reason for the pre-whale to remain isolated and small.
You have no way of knowing that there were no reasons for the pre-whale population to remain isolated and small. Perhaps it was limited to certain depths and temperatures. Perhaps the type of food it required was limited to a small region. Perhaps there were predators in other regions. Perhaps they weren't isolated and small, we just haven't found the fossils yet. Or maybe the fossils are gone now, subducted away.
I can buy that some of the "steps" or changes happened with smaller populations and so no fossils, but we'd have to have perhaps hundreds or more species emerge for this process to occur.
Keep in mind that species divisions are classifications man places upon nature. In reality the population would evolve in a continuous rather than species-step-wise fashion.
Are we to think continually, right after one another, they would all occur in small populations leaving no fossils, with none of them branching out and becoming a widespread population?
Sure. Why not?
Why wouldn't they first replace the old Basilosaurus, and thus grow into large numbers in that same niche?
Any number of reasons. Perhaps Basilosaurus was better adapted to that niche. Perhaps there was an isolating continent or isthmus or current of too warm or too cold water. Perhaps predators. We don't know.
That's what you guys are ignoring here with your arguments based on generalities. There is an ecological niche that clearly enables wide numbers of aquatic mammalian species, and so we should see the process well-documented as one form evolved a little more superiour to the other and filled the niche, but when we look at this niche, we see an abruptness which does not fit with evolutionary models.
Your mistaking abruptness in the fossil record for abruptness in the event itself. In reality the transition probably took thousands of years, although certain catastrophes can upset the balance of things and cause species distributions to change quickly.
You can shout all you want and swear I am offering nothing based on facts, but that's bogus.
No, Randman, you are wrong. You are offering no facts that support your views, only arguments based upon misimpressions. These misimpressions have been called to your attention many times.
You say you want me to follow the rules. Well, you follow them. Quit bringing up creationism, or general concepts, and deal with the narrow specifics of topics and arguments.
Oh, good grief. I say, "Follow the rules,", so you reply, "No, you follow the rules." Could you get off your tit-for-tat kick and just focus on the topic?

Re: another misrepresentation
randman writes:
Note: you said this.
Creationists do not conduct science.
I don't think I was going off half-cocked. Maybe you need to reread your own posts.
I suggest you go back and examine the discussion thread. You will discover that you jumped out of context. That you can remove my statement from it's context and quote a mere five words to make it seem like I was saying something else is no surprise. I suggest that if you want to be listened to when somebody does it to you that you not do it to others. Golden rule and all that.
Since I know you won't actually go back and read the discussion and concede your error, and since I already know you don't care how much of other people's time you waste, in order to defend myself against your false charge that I was saying something that wasn't true and which I wouldn't say anyway since I already know it isn't true (and I have posts here at this forum over the years that make this very clear), here so that everyone can judge for himself whether I was correct to characterize you as having lost the context is all of the relevant dialogue:
Percy in Message 51:
Instead of answering, "Here's how I see it happening...", you instead avoid the topic, usually by filling the space where one would normally expect to see an answer or explanation with one of your stale and empty attacks on evolution.
Creationism/ID isn't suddenly correct if evolution is wrong. If evolution is ever falsified you'll discover that Creationism/ID is still left out of science classrooms because it still doesn't qualify as science. By spending their intellectual energy developing spurious attacks on evolution instead of developing legitimate science Creationism/ID is committing a serious fallacy, one that the courts have repeatedly found transparently obvious.
Randman in Message 60:
That's true. Conversely, if ID or creationism is wrong, that doesn't make evolution true.
Percy in Message 101
No one on the evolution side ever argues in this way. Besides, as far as consideration of scientific alternatives to evolution, creationism/ID is not even on the map because it isn't science.
Randman in Message 107:
Yea, they do, all the time in fact. Evos are always and you have done this as well, resorting to attacking creationism or the Bible or things like that when confronted with criticism of evolution.
Percy in Message 124:
You seem to have forgotten what you originally said, even though I quoted it. You did not say what you are claiming here, and so I was not responding to that. What you said in Message 60 was:
Conversely, if ID or creationism is wrong, that doesn't make evolution true.
What I said was correct, that no one on the evolution side ever argues this way. No one on the evolution side believes that tearing one theory down validates another. A theory's validity is based upon it's explanatory power, not upon the poverty of its competitors.
But to address your point anyway, there is little point to attacking creationism because creationism doesn't have a scientific position to attack. Creationism doesn't work at developing scientifically valid theories but instead strives to create scientific-sounding arguments against evolution. You yourself are an example of this strategy since every request for your views on how the fossil record came to be is met with attacks on evolution.
Randman in Message 125:
It's hard to take you seriously on the issue of false charges when you state:
Creationism doesn't work at developing scientifically valid theories but instead strives to create scientific-sounding arguments against evolution. You yourself are an example of this strategy since every request for your views on how the fossil record came to be is met with attacks on evolution.
You guys say you want discussions with critics of evolution, but then you basically assign false motives and false accusations, constantly, at the people you say you want to have discussions with.
Percy in Message 145:
But the charges are not false, Randman. Creationists do not conduct science. What they do is conduct publicity campaigns against evolution that focus on legislatures, boards of education and common citizens. I'm not telling you anything new, and the courts have repeatedly found this to be the case. The judge in the recent Dover case termed ID a sham as science.
Randman in Message 146 making it seem that I'm saying something I wasn't by quoting a tiny portion out of context:
But the charges are not false, Randman. Creationists do not conduct science.
The first real creationist I ever met was a botany professor at NC State university. He certainly does conduct science, contrary to your false smears.
There it is Randman, for all to see. People can make up their own minds who stayed with the subtopic of discussion and who took things out of context.

randman writes:
Percy, part of the problem is that I am trying to focus on something narrowly tailored to whales. When you or someone else brings up something like uplands species in response to where are the forms between archaeocites like Basilosaurus and whales, it just seems like there is a disconnect. We are talking strictly aquatic creatures at that point.
No, Randman, I was replying to a passage from you that was not "talking strictly aquatic creatures at that point". I was replying to your general statement from Message 150 that I quoted when I replied to it, and that I quote again more fully this time to make clear that you were speaking generally:

You were questioning whether it was reasonable for a species to have a small population and range for long periods of time, and I responded. Clearly I was not responding generally to specific comments from you about whales. You are again wrong.
Please stop forcing me to waste time correcting the record. I grew tired of being called a liar, I grew tired of being accused of making false statements, and now I'm growing tired of correcting false characterizations. Just stick to the topic and stop lecturing everyone about the many trespasses they commit against you. You always detect 17 of every 2 trespasses anyway, so there's no point to it except to emphasize your extreme sensitivity, of which we're already well aware.
There should be something necessarily occupying the same niche.
There is no such requirement. The evolution could have occurred elsewhere, and when chance and happenstance resulted in a species capable of competing successfully against the current inhabitants of the ecological niche, they took over. There could have been an extinction followed by incursion of an opportunistic species into the empty niche. A period which lacks fossils could indicate absence, or it could indicate conditions were prevalent that didn't favor fossilization, or perhaps some breed of scavanger became prevalent that left few remains, or perhaps a period of predation greatly reduced populations. Who knows? Some of the story we may be able to eventually tease out, but most of it likely not. When there's not much left but bones it's really hard to reconstruct what happened in the past.
If any functional mammal evolved, it should have spread and occupied that same niche.
Maybe one didn't evolve at that time. Maybe it did and left no fossils behind. Maybe a "functional mammal" (whatever that is) evolved, but wasn't suited to fill the entire niche. Perhaps it evolved in an isolated sea, or some temporarily cut off part of the ocean.
The idea that functional mammals evolved, but never spread to occupy that niche, and then that group had a subspecies, even smaller, and did the same thing, on and on for millions of years with none of them filling that niche just does not fit the evo story.
I agree that it is unlikely that an aquatic mammal fully capable of outcompeting the current occupier of an ecological niche and with full access to that ecological niche would just sit on the sidelines for millions of years. But you are the only one who has expressed this possibility. No evolutionist is saying this is what happened.
But there are many other possibilities that might have happened. During much of its time in approximate isolation this evolving population might not have had the competitive oomph to outcompete the current occupiers of the wide oceans. Or maybe it did, but the isolation wasn't approximate but absolute because they evolved in an inland sea with no connection to ocean appropriate for them to migrate to the oceans. Or maybe there were other factors keeping them from taking over, such as vulnerability to an ocean-going virus that eventually became less a factor, or a predator that preferred their taste but eventually went extinct.
There are so many possibilities it almost makes no sense to even try to begin discussing them. For you to pick one possibility and insist that it's the only way it could happen just makes no sense to anyone.
If we find Basilosaurus in one strata and then up higher in the same area, we find whales, then the erosion argument does not make sense either because we should see the in-between forms in the strata in the same niche between them, but we don't see the in-between forms.
But the evolution didn't necessarily take place there. It might have taken place somewhere else where erosion did later take place and wipe out the fossil record.
In reality the population would evolve in a continuous rather than species-step-wise fashion.
I am not sure what you mean. Didn't you earlier ascribe to the PE notion of isoloated subgroups evolving into new species? The gradualism model fits even less well.
Don't get this confused with PE. Populations evolve in continuous fashion, I was saying nothing more or less. There is no step-wise species evolution. No organism ever gives birth to a different species (excepting polyploidy and hybridism and some other exceptions). Organisms give birth to offspring that possess very similar genetic makeup to themselves, but not identical because of copying error and allele recombinations, and this process of gradual change goes on for generation after generation. In effect each offspring is a genetic experiment, and the environment selects which offspring are the successes.

Re: Randman, give us your story.
randman writes:
Percy, you taking notice of this? Clearly some evos do argue that one must advance another theory, not just showing how the facts don't mesh with evolutionism.
If you're trying to replace evolutionary theory, then you must advance a theory with greater explanatory and predictive power. Your reluctance to provide any specifics about how ID accounts for the origin of species is fatal.
My comments about the success of a theory not being a function of the poverty of its competitors was made in a different context. A bad theory does not become the "winner" just because all the other theories are worse. Scientists don't create successful theories by badmouthing other theories. They do it by demonstrating the theory's explanatory and predictive power.
I said this in the context of creationism, which doesn't conduct any real science, but rather just tries to contrive convincing sounding arguments against evolution in order to cast doubt about it in the public mind. That's why creationism won't replace evolution if evolution is ever falsified, because creationism isn't really science and has no explanatory or predictive power. If creationism is ever to become successful scientifically then they have to cease putting all their efforts into the "badmouth evolution" bucket and start putting them into scientific research. Real scientific research, not the kind presented at creationism conferences.

randman writes:
Percy, on the one hand, you say that it's not necessary to prove a new theory to discredit evolution and then another you basically say that it is. I realize you do not believe you are doing that. I think you are not seeing the effects of your own argument, but at this point, we can agree to disagree.
Before claiming that I am contradicting myself, why don't you instead quote the part that you think is saying one thing, then quote the part that you think is saying the other thing. As you've provided me nothing to go on, I can't even imagine how you could arrive at such a misinterpretation. All I can do is repeat my explanation in different terms, but I will quote precisely what I am responding to.
...you say that it's not necessary to prove a new theory to discredit evolution...
This is not exactly wrong, but it's not exactly right, either, and it's also not what I said. I said that in order to replace evolution you have to produce a theory which has greater explanatory and predictive power. To quote myself, I said, "Scientists don't create successful theories by badmouthing other theories. They do it by demonstrating the theory's explanatory and predictive power."
...and then another you basically say that it is [i.e., that it *is* necessary to discredit evolution to prove a new theory. --Percy].
I never said any such thing. Please quote the part where you think I said that.
I see evolution as based on outright fraud, overstatement and exagerration. You see creationism and ID as outside the realm of science.
And I've been able to support my views with facts while you haven't. Even the Discovery Insitute disagrees with you. Their wedge strategy openly concedes that ID doesn't fit within the accepted scientific framework, which is why they want to replace methodological naturalism with their own definition of science.
My suggestions are we should talk about the one area we agree on rules to debate. Are the stated and historical evidences for evolution based on overstatements and frauds, or not?
What are you bringing this up here for? Evolutionary fraud is not the topic of this thread. I suggest you focus on the topic of this thread, which is whale evolution. It has been described for you in detail in a number of recent posts that your views on whale evolution and the fossil record are incorrect. I think you should reply to those posts.

randman writes:
It's amazing how you and percy insist on making this a thread on ID.
Contrary to your false charges, I have repeatedly made known exactly what my position is, namely that the past is not static and that effects are not strictly linear in time. You have repeatedly ignored that, and even tried to ban me if I dared bring up my views on threads like this.
As such, your dishonesty in smearing me is hard to see as a mere mistake.
Randman, people are getting sick and tired of your accusations. No one is expressing false charges. No one is expressing dishonesty. No one is smearing you. Everyone is just expressing their opinions. If you cannot tolerate a difference of opinion while maintaining civility, then please just go away. Otherwise, just stop with the accusations and focus on the topic.
I just have to stand in awe at the chutspah it must take to fling about baseless charges of abuse while at the same time abusing all who disagree with you. You jumped all over Jar for explaining that we hold creationists to lower standards, claimed it was an insult, then you come here and demonstrate why we have to do that. Were we to hold you to the same standards we hold evolutionists, you would have been suspended long ago.
Randman, please stop acting like a child. You wouldn't behave this way in public, please don't behave this way here. Keep your attention focused on the topic. Stop accusing people of lying. Stop accusing people of dishonesty. Stop accusing people of false charges. Just stop all accusations. Period.
Now, getting to the issues you mentioned, no one is trying to turn this into a thread on ID. We're just trying to fill in the blanks because you refuse to. This explanation that you just gave tells us nothing at all:
I have repeatedly made known exactly what my position is, namely that the past is not static and that effects are not strictly linear in time.
The question we've been asking is that if you believe evolution is not responsible for the origin of species, in this particular thread for the origin of whales, then how do you believe they came about? Ned's post was poking well-deserved fun at you for refusing to answer this simple question. I suggest you respond to the substance of his post and tell us how you actually think this happened. As I said before, your unwillingness to provide an explanation for the origin of species is fatal to your theory.

Whoa, whoa, whoa, whoa, whoa! You have done no such thing. There are a raft of posts from yesterday alone on this very point where you either did not respond to the post, or if you did you ignored the issue altogether. Your misunderstandings and misimpressions were carefully described. Many possibilities that you failed to consider were listed.
Randman, the discussion does not start from scratch at the beginning of every day. This discussion has a history that you are having a very hard time remembering. Please stop this behavior and begin contributing constructively to discussion.
The stance of evos is to make the claim, as you do, and then demand somehow others disprove it. That's what you are doing, and it leads to evos accepting on faith all sorts of myths, hoaxes, overstatements, etc,...such as the Biogenetic law.
This is off-topic. Please keep your contributions on-topic. No one is keeping you from discussing evolutionary fraud in the right thread. This is not that thread.

Percy, show me the studies that predict, within a range, the numbers of transitional forms either at the species level, or major features at the family level or anything, that would need and would be likely to have evolved to evolve a land mammal to a whale.
Please cite specific studies, not reasons or excuses for their being none.
If you do not quote the "reasons or excuses" we provided and explain why you do not find them valid, then there's nothing we can do but repeat what we've already said. I feel I've explained this enough times and won't repeat myself again. If you'd like to go back to one of the messages where I explained this, quote what I said, and then explain why it is insufficient or invalid or incorrect, then I might be able to respond in a helpful way. As it is, you've once again given me nothing to go on.
Discussions cannot move forward if every new day the discussion begins from square one. We're not trying to imitate the movie Groundhog Day here. Every discussion has a context that moves along from day to day. As I have recommended to you many times, you should quote what you're responding to. That way you can have the text you're responding to immediately above your own response, and you'll be better able to avoid the constant repetition of your initial assertions that typifies so many of your posts.
I have given specifics on how to predict fossilazation rates, and a range per numbers of transitional forms. To this date, neither you nor any evo has ever responded to the specifics of my posts in that regard, but merely repeatedly ignore entirely the specifics and spout vague generalities.
No, Randman, this is not true. Nothing like this has occurred in this thread, you have merely repeated this baseless charge again and again. If you really think you have a message in this thread where you were specific and no one responded then I suggest you find it and provide a link to it.
I am sorry, but anyone not a biased evolutionist can see you are dodging the point. Take, just as one example, my point on Basilosaurus being found in the same region as whales, but none of the theoritical intermediates in between in the geologic layers between the 2. This shows that the geologic column in regards to whale evolution does not support evo models.
Please see my Message 171 that you still haven't responded to. When you respond, please quote something I said so that I can put your response in context and so that you can keep your response apropos to what I said.
You just completely ignored that point, and present a bunch of hypotheticals on why potentially the fossil record could be incomplete. You present no actual specifics, no analysis related to whale evolution, no clear answers as to what could have been occupying the ecological niche between Basilosaurus and whales, for example, nada, and then you have the gall to act like I am dodging you guys.
You are mixing two separate topics. You're refusal to provide your explanation for the origin of the cetacea order is unrelated to the fact that one cannot answer questions for which there is insufficient evidence. If you think you know how such studies could be conducted, then please explain how.

No, Randman, this is not true. Nothing like this has occurred in this thread, you have merely repeated this baseless charge again and again.
You say I have not responded. You said it before as well, and I responded and you did not. Here is the same post again.
No, Randman, you are again wrong. In this post you say:
For instance, such a study would compare numbers of whale fossils with known and extinct whales, and try to asses levels of fossilization frequency. Are they "common" or "rare"?
This point has been responded to many times explaining why this isn't possible, and you have ignored it every time. Instead of responding to our explanations you have instead just rejected them out of hand without explanation while repeating yet again that we're ignoring you.
Let me repeat the explanation again, but this time I'll use a little math. Keeping this simple, the fossilization rate (call it r) for a given whale species is equal to the number of fossils preserved (call if f) divided by number of whales (call it w) that have lived during a given time period. The equation would look like this:
r = f / w
Obtaining values for f over a meaningfully large timeframe might be possible. It depends upon the accuracy of the dated layers and how broad a range of the time period has been exposed to us through erosion. But we have no way of obtaining a value for w, the number of whales that lived during that period. Because we cannot determine w, we cannot calculate r.
Your subsequent argument begins like this:
Then, presuming that similar habitats of either ocean...etc...
But it is of no value because your initial premise, that we can determine the fossization rate, is false.
When you reply, please quote what you are responding to. Thanks!

You were questioning whether it was reasonable for a species to have a small population and range for long periods of time,
No, I wasn't and had you bothered to read and respond to my points instead of constantly ignoring them, you would know that. You want me to respond to you, but you ignore posts like 149 on this thread, and then misrepresent me when you do respond.
You have once again taken things out of context. That conversation was not about "a species" versus "many species". You had accused me of responding generally to comments from you that were specifically about whales. I showed that your were wrong by quoting speaking generally. And I responded generally. The focus of that part of the discussion was on whether you had been speaking generally or specifically. Again, please stop forcing me to waste time correcting the record.
I do not question a species having a small population and range. I question theorizing that among large aquatic, semi-aquatic, and near-water terristial mammals, that we would have one small species in a small habitat evolve into one small species in a small habitat evolve one small species in a small habitat, on and on, hundreds of times and not ever evolving into branches that spread out and grow in sufficent numbers to leave fossils, for say, 5 million years.
I already understand that. I said as much in Message 157:

You remember the part of an earlier post where I said we're people just like you who aren't perfect? Well, guess what? I was right, I'm not perfect. Though I held the thought correctly in my mind, it was not correctly expressed when it reached my fingers. I understood what you said, and I intended to capture it accurately, but it somehow just didn't come out that way. What I should have said was, "You seem to think it rare, almost miraculous in fact, that many species would have a small population and limited range, but that is the case for most species alive today." I don't know how "many" became "a", I can't explain it.
Moving on:
randman writes:
In other words, as I stated before, the PE scenario may work for some species. If we had 30-40% of the actual transitionals represented in the fossil record, the scenario that we don't see the others because they were in smaller populations would make sense, but it doesn't make sense that continual subgroups among very small groups and habitats could continually evolve to fill the missing areas where we don't see whale features gradually emerging. This is especially true considering the habitat is the most favorable in many respects to fossilization.
You've said this exact same thing before. And it's been responded to before. The series of species may have remained small all during its history before the big "breakout" into the big time. Or it may have developed in a region of the world where fossilization wasn't favored. Or in a region which either hasn't been eroded down to the right layers yet, or which has since subducted and been destroyed forever. It is possible that some in the series of species had periods of extraordinary success as measured by population and range, but in a region of the world where fossils from have not yet come to light. There are many possibilities almost too numerous to even think of.
In order to rebut the above and demonstrate that there had to have been intermediate species recorded in the fossil record that we've had opportunity to discover had they been present, you have to show that none of the possibilities is really possible. And that no future possibilities that might one day be uncovered are possible, either. Only when you've completed that exercise can you reasonably conclude that evolution could not have been responsible.
randman writes:
The evolution could have occurred elsewhere, and when chance and happenstance resulted in a species capable of competing successfully against the current inhabitants of the ecological niche, they took over.
Care to explain that? This is a generality, once again. Maybe you could argue that some subgroup evolved into freshwater and then back again into salt water, but we are dealing with areas with a lot of mobility, being aquatic, and areas with good likelihoods of fossilization occuring. Most of all, you are not doing anything but posting generalities. There is no data related to whales in your posts at all.
Wow, you're quoting actual points I made and responding to them. Be still my heart! Thank you, Lord, for you have given me a sign!
Sorry, pardon the sarcasm, but it was just so unexpected I couldn't help it.
Yes, I'm speaking in generalities. It usually isn't possible to know the ranges and habits and so forth of extinct species from millions of years ago because of the incompleteness of the fossil record. In the absence of evidence we can only speculate. No one can magically create evidence where none exists.
Your original question was why no intermediate species are recorded in the fossil record between one "aquatic mammalian species" (see your Message 164) and whales. The short answer is "We don't know." The longer answer involves any number of possibilities. You mention an additional one that I didn't with fresh water habitats. I mentioned inland seas cut off from the ocean. Some or all of the intermediate species may have been very small in population or range. They may have preferred certain environments such as the shallows in regions of the world where this era of life's history is not available to us geologically. I also mentioned predators and disease. There's also the type of preferred food and its range. Temperature variations can isolate populations when ocean currents are too warm or too cold. The continents are constantly moving and changing accessibility.
randman writes:
A period which lacks fossils could indicate absence, or it could indicate conditions were prevalent that didn't favor fossilization, or perhaps some breed of scavanger became prevalent that left few remains, or perhaps a period of predation greatly reduced populations. Who knows?
That doesn't add up. We are talking periods of millions of years. The idea that for millions of years, for example, that conditions in an aquatic environment were different so no fossils occurred, but then again, we got back into fossils for 30 million years is prepostrous. Moreover, that can be checked. Evos can see if fossils occurred during this time.
But conditions keep changing. Perhaps fossilization wasn't favored for millions and millions of years, or perhaps it was and something else is responsible. Perhaps one species of the series ballooned into great success during a period when fossilization wasn't favored, or in places where fossilization wasn't favored. I also mentioned scavengers. Perhaps for millions of years there were species of scavengers that caused the survival of bone long enough to be buried to become very unlikely.
Same with the idea of other predators. All of this stuff you claim is impossible with the "who knows?" could be verified if evos wanted to, instead of making claims that are unsubstantiated.
Given the name that one can make for oneself with new discoveries, the likelihood that evos could find this missing evidence but just don't want to is ludicrous.
Further, we're not making unsubstantiated claims. We're saying we don't really know for sure, but there are any number of things that could have happened. If I dig up a rock in my backyard, I have no way of knowing for sure how it got there. But I can think up a very large number of possibilities.
And that's all we're doing here. We're not saying that we know this possibility happened or that possibility happened, though expert paleontologists can probably narrow down the possibilities far better than I can. All we're saying is that there are many, many possibilities, and your claims that evolution could not possibly be responsible for the whale fossil sequence cannot stand up until you address the possibilities and show how none could ever have happened for whales. And that no one will ever come up with a reasonable possibility.
In a way you've set yourself an impossible task. You're arguing that the evidence doesn't support a conclusion of evolution, but there's so little actual evidence and such a huge number of degrees of freedom that finding a contradiction that would rule out natural processes is highly unlikely.
randman writes:
But if you guys just want to chalk up whale evolution to "who knows?", that would at least be better than every few years presenting a whole new theory just as dogmatically as the first one, such as the Mesochynid theory. I don't think asking evos to actually show that their claims are true is so much to ask for, and I think an answer such as "who knows" indicates evos need to be far less dogmatic in their claims. Otherwise, they are just relying on overstatements.
I think you miscontrue what paleontologists are doing. When they research species ancestry they're not really constructing scientific theories. What they're doing is constructing reasonable scenarios based upon evidence interpreted within an evolutionary framework. As more is learned the picture of evolutionary history changes. The same happens with human paleontologists. Each new discovery changes the picture we have of human ancestry, and there's a lot of disagreement and animosity in this field. But everyone agrees on the evolutionary interpretive framework.
randman writes:
Maybe a "functional mammal" (whatever that is) evolved, but wasn't suited to fill the entire niche. Perhaps it evolved in an isolated sea, or some temporarily cut off part of the ocean.
Then what took Basolosaurus' place for 5 million years?
I don't think we know at this time. We may never know. Maybe nothing in the cetacea order took its place, with the niche being filled by a non-mammal. Maybe conditions did not favor large cetaceans for a while. Who knows? That's a valid, though informal, answer when there's insufficient evidence.
I agree that it is unlikely that an aquatic mammal fully capable of outcompeting the current occupier of an ecological niche and with full access to that ecological niche would just sit on the sidelines for millions of years. But you are the only one who has expressed this possibility. No evolutionist is saying this is what happened.
Then, what are they saying happened? Who knows????
I enumerated some possibilities that evolutionists would actually consider in the following paragraph. In this paragraph I was merely pointing out that you were critiquing a possibility that evolutionists wouldn't consider.
Organisms give birth to offspring that possess very similar genetic makeup to themselves, but not identical because of copying error and allele recombinations, and this process of gradual change goes on for generation after generation.
So we should expect to see then within a given population, gradual emergence and shifting of features, not species appearing suddenly and fully formed, right?
If you could watch them actually evolve through time by way of some kind of time-traveling camera, sure! But all we've got is the sporadic and unreliable fossil record.
