Hi, ICdesign.
ICdesign writes: Thanks for your thoughtful and respectful feedback. Sure thing. -----
ICdesign writes: It doesn't really matter what the produced product is. I think it does matter. The analogy you gave was of a guy who had a bunch of parts and a specific task to complete. The theory we propose for evolution is without a specific task to complete. So, it would be more akin to Mr Chance being given a pile of assorted stuff and being told to build something that works, and having Mr Selection stand over him and test it at each step to determine whether or not it works. So, Mr Chance isn't told that it has to have four wheels, or that it has to be a vehicle for transportation, or that it has to run on gas, or that it has to have a manual transmission with forward and reverse gears. Rather, he's simply told that it has to work. ----- Now, in terms of real-world evolution, "something that works" implies an something that survives and reproduces. Outside of those two standards, there are no rules about what the end-product must be. Of course, like Percy said, feedback from the environment can later make the standards of survival and reproduction include some specific requirements. For example, if a new predator arrives, than the standard of survival will include the requirement of a way to deal with that predator. But, even then, no specific way of dealing with the predator is required: the only requirement is that the predator be dealt with. So, adaptations for fast running, or heavy protective armor, or adaptations to live in the dark or to hide in a burrow, could all be ways to successfully avoid the predator, and thereby meet the "survival" standard. ----- Other examples of specific requirements added by environmental feedback may be:
And, the list goes on. You can see that there is not necessarily a single "right" answer to any of these dilemmas, which provides ample opportunity for different evolutionary "solutions" to arise in response to the same challenge. For instance:
This is why evolution doesn't work toward a specified end-product: because it doesn't "know" beforehand what challenges each lineage will face or how each lineage is going to respond to these challenges. Each lineage has to address the challenges as they come, and, furthermore, the response of one lineage to one challenge can easily create a new challenge that another lineage has to respond to. It can be very messy, very dynamic and very unpredictable, so we should also expect the end-products to be messy, dynamic and unpredictable. Thus, they shouldn't be specifiable beforehand. -Bluejay (a.k.a. Mantis, Thylacosmilus) Darwin loves you.

Why?
in what would be an impersonal, purposeless and wholly material universe anyway.
What does this have to do with anything?

About the finer details, yes, not about the "whole picture".
Because one offspring survives instead of another may not mean it has greater evolutionary potential. The lucky chicken that survived the hungry fox's nocturnal raid on the chicken coop may well have been suffering from insomnia on that night. Survival of the fittest thus becomes "survival of those that survive," which doesn't tell us a great deal.
Actually, that's exactly what it means. However, you'll find that luck will run out one day, if the chicken survived purely due to luck on one night, does not mean it will survive the next. If the chicken survived because it could outrun the fox (just an example), then its chances of surviving the next night are very much more improved, and so in turn will its offspring's be.
At any rate lets get back to my point of construction, Mr. Chance and your original question of why I think ToE is impossible. In my analogy Mr. Chance would have a chance of success be it ever so slight, correct.
Yes.
But now lets paint a more accurate analogy of reality and take away Mr. Chances brain all together. No thought. Nothing but a blank screen. What are his chances of building anything now? Zero right? It would be completely impossible.
Well yes, but only because he is a person, and people need brains to pick and choose. Nature (or rather, mutation), is not an intelligent, nor a personal process.
Evolution is Mr. Chance with no brain.
no, it isn't really. Evolution is Mr. Chance and Mr. Selection, working together, the one randomly selecting parts, the other telling him if they are wrong.
t wouldn't matter if there WAS a Mr. Selection because without thought nothing can happen.
Of course stuff happens without thought, we see it all around us the entire time. Why do you think nothing can happen without thought? Does rain think?
How can evolution build anything if all it has is a blank screen. It comes right back to being so simple a child should be able to understand.
But evolution is not a blank screen. Evolution is Mr. Chance and Mr. Selection working together.
I have to run but I would like to talk more about the aforementioned systems and purpose when I return tomorrow.
Of course mate. Whenever you feel like it. Let me know what you think about my "Evolution is Mr. Chance and Mr. Selection working together bit". Are you saying I don;t understand the thing I am trying to "defend" to you? Am I, and everyone else on this thread, so ill-informed over what evolution is that we (who have studied it, let me remind you, maybe not university level, but still), are so "blind" or stupid we got it all wrong?

One of the neat things about Evolution is that there is not just one Mr. Chance, there are billions and billions of them. And the results of all those experiments get filtered and those that work, even just barely work, pass through the filter. It is only those that simply don't work at all that get filtered out. Even the experiments that don't really do anything get through the filter as long as they are not so bad that they prevent the critter from living long enough to reproduce.

Hi ICdesign,
All you guys seem to be talking about survival of the fittest for up and running, fully developed creatures. Yes. that's because we are talking about the ToE, which deals with extant organisms, not their first origins.
What I have been trying to get to is the construction process of creatures to begin with. Two answers; a) The "construction process" in the example you have been using is analogous to random mutation and the laws of chemistry. b) We are talking about evolution, not the first origins of life, so the original "construction process" is not part of the analogy.
This whole "self-improvement" program the ToE adheres to is bogus in what would be an impersonal, purposeless and wholly material universe anyway. I agree, you are quite right. In an unguided universe there would be no objective value that could be used to define "improvement". That's why evolution is not a matter of "self improvement". Proponents of evolution don't regard the process as "progress". Descendant organisms are not necessarily any "better" or "worse" than ancestral ones; they simply pass through the test of natural selection, maybe with success (offspring) or with failure (no offspring). No value judgement need be made.
It should be mentioned here that even among evolutionary theorists there remains widespread disagreement. There really isn't. There is no "widespread disagreement" amongst biologists on any important aspect of the ToE.
Because one offspring survives instead of another may not mean it has greater evolutionary potential. The lucky chicken that survived the hungry fox's nocturnal raid on the chicken coop may well have been suffering from insomnia on that night. Leaving aside that the chicken might have a genetic cause for its insomnia... You are right. Sometimes survival is a matter of chance. Sometimes you zig when you shoulda zagged and you pay the price.
Survival of the fittest thus becomes "survival of those that survive," which doesn't tell us a great deal. But that's wrong. Just because chance plays a role, does not mean that natural selection isn't involved. Some organisms are, undeniably, better equipped to survive and reproduce than others. Natural selection can affect these organisms. It is not pure chance or luck. Luck is involved, but natural selection is involved as well.
But now lets paint a more accurate analogy of reality and take away Mr. Chances brain all together. But that's because Mr Chance is just a character in an analogy. You are arguing the analogy, not the argument itself. You have broken your own analogy. Humans can't exist without brains. The blind process of chance can and does. Therefore, your analogy breaks down here.
IT IS IMPOSSIBLE !! Please stop shouting at people. It really doesn't help. Mutate and Survive On two occasions I have been asked, — "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question. - Charles Babbage

ICdesign writes: Actually, no I don't. All you guys seem to be talking about survival of the fittest for up and running, fully developed creatures. What I have been trying to get to is the construction process of creatures to begin with. All species since the first life have been "up and running, fully developed creatures." You wouldn't say amoeba or algae aren't fully developed, right? You wouldn't say starfish or swordfish or frogs or toads aren't fully developed, right? You wouldn't say platypus or meerkats or bonobos aren't fully developed, right? In fact, can you think of any organism that isn't fully developed? Of course not! And neither can we. So why do you have this crazy idea that evolution requires that fully formed organisms evolve from half-formed creatures?
Evolution is Mr. Chance with no brain. It wouldn't matter if there WAS a Mr. Selection because without thought nothing can happen. Mr. Chance's brain is not a valid part of the analogy. Mr. Chance putting parts together randomly is analogous to mutations randomly altering parts of the genome. Mutations do not require thought. The analogy to removing Mr. Chance's brain would be to prohibit mutations. In other words, it would make no sense. The purpose of an analogy is to make something unfamiliar easier to understand by likening it to something familiar. Everyone is familiar with people, so constructing analogies to the natural world using people is a very common way of explaining things, but the fact that people are intelligent is rarely part of the analogy, and certainly not in the analogy of Mr. Chance and Mr. Selection. Did you see my comparison of breeding (people make the breeding decisions) to natural selection (the environment makes the breeding decisions) in Message 401? This comparison should be pretty helpful in understanding that there's no intent and purpose in nature. --Percy

Of course. I just want to keep it simple with one Mr. Chance for this example for now, elaborations can always follow the basics.

All you guys seem to be talking about survival of the fittest for up and running, fully developed creatures. Like Percy states above, there is no such thing as a "not fully formed" organism. Secondly, of course we are focusing on up and running organisms. Dead organisms do not evolve.
This whole "self-improvement" program the ToE adheres to is bogus in what would be an impersonal, purposeless and wholly material universe anyway. What tests did you run to determine that natural selection is bogus?
It should be mentioned here that even among evolutionary theorists there remains widespread disagreement. Such a statement usually warrants a description of what scientists disagree on. Scientists do agree that natural selection is a real and viable mechanism. So what exactly is this disagreement over?
Because one offspring survives instead of another may not mean it has greater evolutionary potential. The lucky chicken that survived the hungry fox's nocturnal raid on the chicken coop may well have been suffering from insomnia on that night. Survival of the fittest thus becomes "survival of those that survive," which doesn't tell us a great deal. Populations evolve, not individuals. On average, the less fit do have fewer offspring than the more fit. This can be predicted beforehand, before a population is challenged by selective pressure. To use an oft cited example, you can predict beforehand that dark moths will survive at a higher rate than light moths in an environment where the trees are themselves dark. What this tells us is that ratios of alleles will change in response to environmental pressures. How is this not important information?
But now lets paint a more accurate analogy of reality and take away Mr. Chances brain all together. No thought. Nothing but a blank screen. What are his chances of building anything now? Zero right? It would be completely impossible. Then your analogy is a poor one since we observe organisms without brains evolving in real time. We see random mutations that confer antibiotic resistance spreading through populations by evolutionary mechanisms minus any brains. You have just admitted that your analogy is irrelevant to biology.

On an earlier post you stated that you understood the TOE. This comment clearly shows that you in fact do not understand the TOE. You should probably learn about the theory before you continue posting. Facts don't lie or have an agenda. Facts are just facts

Evolution is full of nothing but double speak. It has no thought, no purpose. no intent, yet constructs all the sophisticated systems that make up life.
In the real world a system cannot be built without intelligent thought and action yet you choose to believe evolution is capable of doing so. You can't produce any evidence or model of this impossible feat taking place anywhere on the planet. The best I have ever seen any of you offer is some insignificant little bacteria mutation that shows nothing of how a sophisticated system can construct without intelligence. Please save your "what is your test for a sophisticated system" comments.That may be valid questioning in your opinion Percy, but its only valid to evolutionists because you have no evidence as to how evolution can produce systems so you play shell games and create a maze of smoke and mirrors that you hide behind. Maybe survival of the fittest is a good enough magic bullet to explain how the impossible became possible for you guys, but it just isn't working for me.

Which is fine, but until you can present a model that explains what is seen better than the current model, you have nothing.

Hi ICdesign,
There's not much point to starting the discussion over again from the beginning. We *are* making progress. Do you think you could take a stab at responding to some of the specifics of what people have recently posted in their responses to you? --Percy

The ironic thing is that you will now equivocate (in a sense 'double speak') about what 'thought', 'purpose', 'intent', 'construct', 'sophisticated', 'system' and 'life' all mean - or rely on too broad a definition.

I did respond Percy. Why don't you respond with evidence that a sophisticated system can be created without intelligence? All your survival of the fittest theory can show is death of the unfit.
