Sure about that?Oh noes, he's an imposter...
The Bush we see on TV is proof intelligent evolution is bogus.

Oh, all these 'needs' and 'beliefs' of information and what it 'cares about' is restricted to terrestrial information! And I thought information on, say, Mars would have the same kind of feelings and needs! But no! Martian information is much more frugal, correct?
That's sorta the problem here in discussing the analogy: at least one supporter of the analogy sees emergent properties as having a different form of existence from non-emergent properties and therefore can be "abstracted away" when they are inconvenient to the analogy.
On Mars information comprises indivisible entities known as bars.
This is interesting. At what point does "instinct" become "intelligence"? Does a pride of lions, for example, ambush its prey instinctively or intelligently?
Again you show that you don't get the analogy.Originally Posted by jimbob
No, self-replication is nescessary but not sufficient for life. A virus is not usually considered to be alive, but viruses self-replicate and evolve.
I am using "reproduction" simply because that is more common in biology than self-replication, but when biologists talk about reproduction they are talking about self-reporduction i.e. self-replication
Information does not self-replicate. It USES other things to get itself replicated.
With that argument, how do you separate the different processes of selective breeding and evolution?
How does that argument allow you to seperate the processes of genetic engineering and evolution?
How does that argument allow you to seperate the (hypothetical) process Intelligent Design from evolution? "The information used a deity to evolve".

Do you mean "invisible"? Because apparently they are, judging from the jpeg.
The UK Mars Bar Index (MBI): In his informative and entertaining articles in the Financial Times (1981 and 1983), the late Nico Colchester introduced the concept of using the Mars Bar as a standard unit of currency. He argued that the recipe has stayed pretty much the same, as has the production, distribution and retailing methods. Therefore, other prices could be valued in terms of the typical price of a Mars Bar (1MB), allowing direct comparisons to be made over time.

You'd need to be desperate wouldn't you? Even Bush has a much wider choice I would imagine.President Bush, up to now I'm impressed by your grammar and spelling. Is Condie taking dictation on your lap?
The most powerful word in the English language... Uma.
Our ancestors were all sufficiently adapted to reproduce. It didn't matter that other organisms reproduced more "optimally", as long as our ancestors reproduces suffficiently well, (whcih they obviously did).Then it's not towards reproductive optimiality is it then?Originally Posted by jimbob
However all our ancestors did manage to reproduce, which is the only "test". The optimisation is towards "variants" that manage to produce at least one breeding offspring per parent.
YES. That is why self-replication works wirhout any arbitary selection criteria, whilst other systems don'tJimbob, if "breeding" stops then there are no further iterations are there?Quote:
Without the variants "breeding", nothing.
Why is that not self-replication of some type? Where is the difference?I don't see anyone defining the selection pressures out here, do you?Quote:
If the selection is completely haphazard, then there will be no selection pressure.
You leave the system long enough and it'll formulate it's own, natural, selection pressures iff:
1) Not all current objects in consideration in the current iteration will be part of the next iteration
2) The selection of which objects are and are not included is self-defined by the objects themselves
This was a derail, but you keep asserting that there is no true randomness, whilst there is evidence that quantum effects are. If these events can get maginified by chaotic systems to affect macroscopic events then macroscopic events can also be truly random. the classic example is Schrondinge's cat. A more relevant one might be a radioactive decay causing a mutation that leads to cancer in an organism before it breeds, or causing some offspring to have a slightly different set of traits that affect their prey's survival...I cannot understand that random stream of text.Quote:
No, you keep asserting that there is no randomness; there is strong evidence that quantum events, like radioactive decay are truly random, these can cause mutations, so at least some mutations are random, even if most might be merely pseudorandom.
I cannot understand that random stream of text.(You seem to forget that computers are strictly non-random by definition - if you're going to be silly and talk as if the fundamental substrate of reality is ultimatelty consequential in these models then so will I).
No I am asking why you think that is not self-replication ifPredator/prey.Quote:
At this stage I would be asking how the simulation worked as you seem to be saying that there is no selection criteria.
1) Not all current objects in consideration in the current iteration will be part of the next iteration
Predator eats prey - survives.
Predator does not eat prey - dies.
Predator replicates.
Prey eats grass - survives.
Prey does not eat grass - dies.
Prey replicates.
2) The selection of which objects are and are not included is self-defined by the objects themselves
Predator eats prey.
Prey avoids predator.
I imagine at this point you're screaming, "OH THE HUMANITY, WHERE IS THE RANDOMNESS!?!?!"
Southwind's algorithm isn't. It could just as easily be altered to select for non-selling variants as for sellin variants, especially with the infinite resources allowed.Kinda impossible to avoid - objects not utilised in the next iteration are, well, not utilised in the next iteration.Quote:
So you are selecting on "survivability".
That's true of any algorithm.
Reproduce itself then.See above. I don't think you're considering the pure abstract of what it must mean for code to "reproduce". (Any time data is copied it's "reproduced" - think about the etymology of that word.)Quote:
Did the surviving code "reproduce". If so then it is self-replicating according to my definition.
You need a source of variation to work, analogues of sexual reproduction would "breed" the best combination of the available traits, but further pseudorandom alterations in the gene-analogues would be needed to improve on this.Don't even need the alterations to prove my earlier points - the newer simulation didn't add a whole lot of difference. Predators/prey (effectively) switching roles doesn't significantly change the dynamics.Quote:
After a certain time, those organisms that are still surviving are copied, but with (pseudorandom?) alterations. This next generation is left in the same fashion and the process repeaded many times.
If there is not self-selection, which is the important feature of self-replication, then something else performs the selection.What exactly is artificial about it? Be consistent now - you said artificial selection is where one tries to attain a specific variant as a goal. I have no specific variants in mind at all. I don't control the simulation once I start it (unless I choose to).Quote:
If that is the case, you are selecting for organisms that survive and using "artificial selection" to "breed" them.
I have no idea, none whatsoever, as to why you think what you proposed is significantly more accurate other than for the obvious reason that it is a richer world model.Quote:
In this case the selection would not be for surving for any length of time, but for reproducing, which would include "surviving long enough to reproduce". It is quite possible that a "parent" organism could evolve to sacrifice some if its resources to boost the reproductive success of its offspring.
There's more functional possibilties afforded the variants by the world itself which allow for more reproductive strategies but apart from that I fail to see why what I had made previously is more "artificial" than this.
Because they are different.OWhy would I want to ?riginally Posted by jimbob
With that argument, how do you separate the different processes of selective breeding and evolution?
Because they are even more different.Same question.Quote:
How does that argument allow you to seperate the processes of genetic engineering and evolution?
I wasn't asking why it was implausible, I was asking how your viewpoint woud state that there was any difference in the process.Occam.Quote:
How does that argument allow you to seperate the (hypothetical) process Intelligent Design from evolution? "The information used a deity to evolve".
