  2. Re:"Natural" Selection on Natural Selection Can Act on Human Culture · · Score: 1

    Nonsense!

    For natural selection you need to following ingredients:

    1. inheritance: skills to build boats and their designs are passed from father to son.
    2. mutation: not everyone is as good in boat building, some sons didn't listen very well, and some get creative
    3. differential replication: methods and designs to build GOOD boats will have more change to be replicated than designs of boats that sink to the bottom. Here, we probalby leave the path of father to son inheritance, and ideas also start to spread horizontally.

    Once these ingredients are in place, natural selection automatically kicks in and starts doing its almost magical work. Now BEAR IN MIND that not the boats are replicating here! BUT THE METHODS TO BUILD A BOAT! Building the boat itself and using it to travel across water is just a happy side effect. The method of building the boat, the very knowledge and skills itself are here the "living thing" that tries to survive and convince us to pass our knowledge to other hosts.

    To us, that indeed _seems_ to be just good design practice, but that's just because we're part of the equation. A design practice that is good is more likely to be passed than one that is bad. We're both the breeders and the selectors! But it still is natural selection.

    What is the most successful recipe for a cake? One that is the most delicious of the entire world but is kept as a secret a dies when its creator is sent to the grave, or a less delicious one but is freely passed from one man to another?

  5. ATAATAAATAAAATAAAAAT... on Texas Science Director Forced To Resign Over ID Statements · · Score: 1

    If we look at a DNA sequence, how do we tell the difference between a evolved and a designed sequence? If we look at the functional parts, we probably wouldn't be able to. But, say, I was the "designer". Me, I wouldn't be able to resist leaving some signatures behind. To "watermark" my design. For two reasons: one: to label it to "other" designers as /my/ work, and two: as a puzzle, an easteregg, to see if those little humans would be able to figure it out.

    So, what would I use as watermark? You can't simple write "God was here", because the chance that those little humans would understand your language would be rather slim. But even they would share our language (Hebrew perhaps?), you still must encode it in a sequence with only 4 symbols A, T, C and G. Even if we can assume those little humans would understand the concept of encodings in base 4, we hardly can assume that our "ASCII" table would be the same as theirs. So, what would be a good sequence?

    I would use the same kind of sequences we would be using as a clearly artificial signal we would be sending to aliens, for example: prime numbers, or a binary sequence like 101001000100001000001 ... Something that stands out as being purely artificial and not being "evolved" or having any kind of function.

    So, if we would find in DNA something like the sequence ATAATAAATAAAATAAAAAT ... long enough for not being a product of chance, finding the same species back in different species that would - according to darwinian evolution - not be related, and finding different sequences like CGCCGCCCGCCCCGCCCCCG ... in species that would be more related (say like god A designed the horse, but god B designed the donkey, or gorilla vs chimp), then I would be scratching my head and I would see two possibilities:

    1. Those animals are genetically manipulated by humans, and closer investigation shows that not _all_ horses and donkeys have the same watermark
    2. Maybe horses, donkeys, gorillas and chimps really were designed by some "intelligent designer", whether that be some aliens or a god ...

    Just my thoughts,

  6. Re:Darwin's theory of natural selection on Evolution and the 'Wisdom of Crowds' · · Score: 1

    You're right when you state that without mutation there's nothing to select from. I did not suggest that you don't need the mutation part, only that the emphasis should be on the selection part, not the mutation part. It is hard to describe any "effect" like complexity to only one part (mutation or selection), because Darwinian evolution of course is an interaction of both. But you can see it like this: selection=engine, mutation=fuel. Without fuel, the engine won't run, but the fuel is meaningless without the engine. The emphasis is on the engine, because that's the part that actually does what we want to.

    About complexity, I'd rather say that the selection part is responsible about creating complexity, because that's the "designer" part that "recognizes" more complex (well, better) mutations. The mutation part is unaware of what it is doing and does not have any grasp of complexity whatsoever.

    Furthermore, the mutations don't need to be random at all. If you know anything about Monte Carlo simulations/integrations, you know you can get better results with less samples if you draw your samples from a distribution that is similar to the integrand. Likewise, the mutations can be aimed at "improvements" to get better results in less generations. Of course, this is not the case in nature, or at least nobody knows of it, because there's no way for nature to "aim" the mutations, or at least no one knows of such a mechanism. But it other applications of evolution this might be the case. For example when designing a car, one "master" (the selector) might have 10 designers that - starting from a given design - try to make variations that they think would be better, and then the master would select the best variation. This would give better results faster than - let's say - using 10 monkeys that make the variations in a "uniform" direction.

    The real designing part - creating complexity - would be the master that selects the best results, and not the 10 pupils (intelligent or not) that make the variations. So, selection is really the keyword here, where the emphasis should be on. But of course, evolution still is selection _and_ mutation.

    Does this clarify a few things?

  7. Re:He doesn't address the evolution of ideas on Evolution and the 'Wisdom of Crowds' · · Score: 2, Interesting

    I have two things to say:

    1. Religion does _not_ lead to ethics. There was moral before religion. You don't _need_ religion to have ethics. Religion is just a _very_good_ selling argument for ethics. Without religion, you actually have to think why this or that ethic view of point is a good one. With religion, ethics get a virtual "absolute" character so it gets much easier to impose it over a large number of people without them questioning you.

    2. The "fittest idea or world" (or using Richard Dawkins word "meme") is not necessarily the one that is "best for the people". Just like there are "evil" viruses than spread over the biological world but that are very bad for its hosts, there are "evil" memes that can spread over the world, catch on, but are very bad for the population itself (politics of fear, limiting freedom for the sake of [...])

    It is however still an interesting question whether it would be better to have a society of "fooled" people who might just be happy, or a society of "aware" people that now have a bit more trouble understanding their world.

  8. darwinian evolution as Monte Carlo ray tracers on Evolution and the 'Wisdom of Crowds' · · Score: 1

    You seem to incorrectly assume you need multiple mutations at once to apply natural selection on. This however is not true. All you need is mutation (that even doesn't need to be random) and selection. There are no further conditions, although of course some "variants" work better than others, depending on the application. For example, in biology sexual mutations result in faster evolution than asexual mutations. For the last couple of millennia, mankind's evolution is largely cultural driven instead of being a biological evolution. Simply, because cultural evolution is much much faster. Let me rephrase that mutations in Darwin's theory don't even need to be random. If you can "aim" your mutations in a beneficial direction, your success rate of finding a such one will be much higher than if you "uniformly distribute" your mutations. Compare it to Monte Carlo integration: if you can draw your samples from a distribution that roughly resembles the integrated function, you will have a much better result with less samples than by using a uniform distribution. So about wikipedia. Are there mutations? Yes, although not exactly random, most of them are "intelligent" mutations, by which I mean that most edits will be "aimed" at being a good mutation. This way, we need less mutations to make real progress. Is there selection? Of course, not all edits are good edits and that's where selection kicks in. All edits are evaluated, and if they are good, they have a much bigger chance to be accepted.

  9. Darwin's theory of natural selection on Evolution and the 'Wisdom of Crowds' · · Score: 5, Insightful

    Are you kidding me? Calling Darwin's theory a theory of random mutation show how little you understand of it, because you emphasize the wrong half of his theory. There's basically two parts about Darwin's theory: (1) mutation and (2) selection. Most people consider the first one as most important, but nothing could be further from the truth than that. It's SELECTION that is the keyword here. The mutation part is merely the "fuel" that feeds the selection "engine". In fact, the mutation doesn't even need to be random at all. Let me say that again:

    The mutation in Darwin's theory does NOT have to be random!

    Although random mutation is perhaps the most effective way compared to its complexity. It surely is the most simple way for nature to "implement" it. And most of the time it results in very good "fuel". About your example: although the mutations are made by intelligent designers, some designs are rejected and some accepted (to be built further upon). The mutations are not random, but the selection is still in place. That's good enough.

    So if you don't want to call Darwin's theory a theory of evolution, call it a THEORY OF NATURAL SELECTION instead.

    Keep in mind: you do not need DNA, big gene pools, parallel mutations, sexual mutations, ... to have a Darwinian evolution at work. It doesn't have to reflect the biological method of evolution at all. At its core you only need (1) mutation (2) selection. Once you have that, you have Darwinian evolution. I believe it was Richard Dawkins who coined the term MEME to apply Darwin's theory to cultural evolution! Though it is has entirely different mechanism than biological evolution, it still consists of mutation and selection. Not all variants work equally well though: sexual mutation seem to work better than asexual mutations , cultural evolution is much faster than biological evolution, because the latter can only pass information between generations what is very slow. The evolution of mankind in the last few thousands of years are mostly cultural driven.

  11. Re:today's records use bad tonemapping on Does Going Digital Mean Missing Music? · · Score: 3, Informative

    That's not really what I'm aiming at. But I largely agree.

    Chances are that your old classical music LPs have been compressed for dynamic range too. But that was simply due to the fact that an LP simply doesn't have the dynamic range required to fully record classical music. So the compression was a technical matter. Compare it to the need of tonemapping to display a perfect HDR image of a physical scene on a monitor or print.

    Today however, pop music is compressed for dynamic by design, simply to make it sound louder than other songs when played at the radio or from a jukebox where the volume knob is left untouched. Compare it multiplying your image by a factor ten simply to show it "brighter" than on the monitor next it. It will "appear" brighter if you don't look too closely, but it will have lost much detail simply because it clips to your monitor brightness.

    Modern pop music may not have the same dynamical range as classical music, but it still has more potential than you find on most of today's CDs:
    (a) live performances _do_ have the punchy bass drums and highlighted snares lacking on the album, because the PA can deliver what's requested without clipping. Unless your band is called Cradle of Filth (they suffer the EVERYTHING LOUDER THAN EVERYTHING ELSE syndrome even on stage).
    (b) pop albums of 20 years ago don't suffer this problem. They still have lots of headroom. Even trash metal records (Metallica - Kill 'Em All) behave very well with lots of dynamic range and lots of headroom. Yet, the moment they are remastered, that's totally gone. There's suddenly clipping all over the place. It's still the same music!

    So it's not the music. It's the mastering.

  12. compressed music != better music on Does Going Digital Mean Missing Music? · · Score: 1

    I challenge you to listen to your compressed ipod sound on the same volume as that live concert. I wonder if you still will think it's better. It probably won't be very good for your ears though! live convert volumes rarely are anyway.

    The reason people think compressed music sounds better is actually a short term effect: because it sounds louder at the same volume setting. Think of "turning the volume knob to 11". However, if you tune the volume so that both appear to be as loud (perhaps you can use a sound pressure level to measure this), then you will notice the uncompressed music has much more punch and is much more pleasant to listen to, while the compressed music will sound very flat.

  13. Re:Today's records ARE technically inferior on Does Going Digital Mean Missing Music? · · Score: 3, Insightful

    If music is compressed, limited and clipped like it is on many records today, there really isn't much argument for the need of an extra quality carrier. The quest of the artists, producers or record labels to GET THEIR MUSIC LOUDER THAN EVERYTHING ELSE, causes the dynamic range of music to be sacrificed in order to bump the sound as close as possible to the zero dB boundary. This loudness war causes severe digital clipping, and the distortion you get from it is much MUCH worse that what you get from the MP3 conversion with a decent bitrate.

    Not only that, but the music loses every punch, melding all elements in one flat sound, tiring your ears. It's the same with the super audio CD. why needing a carrier with more bits and higher sample rate if you're even using what's available on a CD today?

    Really, there's no need for ultra high fidelity equipment or sound carriers if the signal is broken by design at the factory!
