Just a quick comment while I ponder other things -
The wave/particle duality does mean that a photon is a simultaneously a wave and a particle as demonstrated by Young's double slit experiment using single photons.
The position in the em spectrum determines the energy level of the photon (and therefore of the wave) not whether it behaves as a wave or as a particle. Irradiating matter with em-radiation of shorter wavelengths releases electrons of higher energy, but the quantised effect does not change - one photon releases one electron.
Here is conundrum for you: A photon is called a massless particle since it has no rest mass (also called invariant mass), in particle/wave duality a photon particle is simply energy in the form of electromagnetic radiation and as we all know it propagates through a vacuum at the speed of light. Applying the Einstein equation we can calculate the effective mass of that energy packet, (m=E/cē), which would be the effective mass of a photon, (the mass that is affected by gravity for example - as demonstrated by gravity lens effect of light bending around large stellar masses) - this mass is called the relativistic mass.
A body (let's call it matter since it is a mass that occupies a volume) that radiates a single photon loses rest mass equivalent to the relativistic mass of that photon - that photon can propagate (travel) through a vacuum and strike another body which will gain rest mass by the same amount. That is called a closed loop system and the conservation of mass is preserved since no mass is lost/destroyed - the combined overall rest mass is the same. Now consider a system where the second body did not exist and so the photon never arrived at a destination, remaining forever as a free particle - the rest mass of that system is now light by the mass of one photon - the photon can never rest since it is always moving at the speed of light - it remains as massless energy - this is called an open loop system and the conservation of mass fails. The question then becomes - is the singularity present prior to the big-bang (assuming that is the concept you are arguing against) an open or closed loop system?
I will freely admit that I have not delved into that aspect of photon creation, so I will not say that your information is correct, or incorrect. I would have to read more about the subject.
However, in practical studies of x-ray photons for example, the mass is not transferred to photons. The "body" (tungsten in this case) emits photons when one of its shell electrons are either knocked out of orbit, or electrons bending through the atom (caused by the charged nucleus) release energy because they are slowing down. The tungsten retains its mass when it refills the affected electron shell. The incident photon also does not add net mass to whatever it strikes.
Also, wave/particle duality does not mean that a photon IS a wave and a particle, it just exhibits SOME of the behaviors, depending on where in the em spectrum it resides.
On cursory reading, I would say that to answer that, I would have to assume a hypothetical situation rather than an actual situation, which would not be a strong argument for either case.

But herein lies the problem.......
You can't get past the problem of how matter came to be. All these posts, all these threads, all these arguments....pointless until you get past the problem of the "spontaneously appearing matter".
The Theory of Evolution, natural selection, punctuated equilibrium, genetic drift, mutation, speciation, biological fitness, abiogenesis, adaption, the primordial soup, amino acids, RNA and DNA have nothing to do with "spontaneously appearing matter" - this is not a pack of cards that collapses to nothing just because the origins of the universe cannot be explained in a way that pleases you. Whether the Universe originated in a big-bang, has always existed, is bouncing around like a yo-yo, slides in from parallel multiverses or rides on the back of a giant turtle is as good as irrelevant to the origins and evolution of life. If there is some cosmic connection between quantum cosmology and quantum biology (such as quantum tunnelling) then it is possible that there is a relationship to the origins of both, however that does not effect the mechanisms of either.

So go look this up and copy and paste some links and videos about where it came from....but it will fail to answer it satisfactorily, every time.
I think you are attempting to overcomplicate the issue by using areas of cosmology that we haven't solved yet as proof that everything else is wrong.
As I volunteered before - show us some of those scientific explanations that don't make sense to you and let's see if they make sense to me or anyone else here.
Anyway...

I will simply disagree. I believe micro evolution is extrapolated into macro evolution, but is not the same.
There is simply no proof of one species evolving into another species. I understand fossils are rare but come on, there would still be as many fossils of mid-species organisms as there are of standard species. Why aren't there? There's that one of the flying-bird-dinosaur (quick someone look it up and post it to appear more intelligent than me), but that one is still up for debate. Sure a common creationist argument..and evolutionists have been conditioned to say "oh well just another of the same creationist argument" and dismiss it without even thinking about it. Either that or go look something up that agrees with their point and paste it here. People really need to think deeply about the simple questions for themselves and use some more deductive reasoning instead of being duped by people with agendas. I mean some of the science is valid, but extrapolated to an unreasonable point.
I mean there's the platypus...but I think God was just showing his sense of humor on that one.
Regarding the wolf to dog video. This actually goes against your theory of evolution and is used in the creationist argument. (But you already knew that I'm sure)
You do realize that there is no species change here right? Micro-evolution is a fact, we see it, we breed it. But not species differentiation (macro-evolution). These are highly different. Breed a bird into a velociraptor and I'll be impressed.
I believe the only "evolution" happening is de-evolution or devolution depending on who you ask. In order to breed animals such as dogs or horses, you "breed out" bad genetic information. You are not "breeding in" better information. So in each case we are talking about genetic information being lost. Nothing is gaining genetic material, only losing. (Detractors paste your wikipedia link here, we know how reliable they are) So I postulate that humans are less intelligent and less healthy than when man began. That's why we have so many imperfections, crooked ears, asymmetrical faces, more cases of cancer, DNA anomalies.
A text book example on how Creationists pervert the theory of evolution. There's absolutely no need to comment on those points, they speak for themselves and only underscore how desperate Creationists have become over the years. If all else fails, try to discredit your opponent.
I thought you weren't responding to any more of my posts.
And besides, where in that post did I discredit you?

Did you read Dawkins book - especially the chapter about intelligent design?

The human eye, since you mention it, is a good example, with the retina placed facing inward, and the nerves on the inside of the eyeball, so that the light has to pass through the nerves in order to reach the receptor cells.
I have mentioned this before (man these multiple threads on the same subject are getting confusing...) but this design flaw in the human eye is corrected in the octopus eye. But even then the octopus eye is still not the pinnacle of eye evolution, the eye of the mantis shrimp is even "better".
Careful though with those words - "corrected" and "design flaw" could play into the hands of Creationists.

Albert Einstein had this feeling of awe which he explained in this quote:
"I said before, the most beautiful and most profound religious emotion that we can experience is the sensation of the mystical. And this mystically is the power of all true science. If there is any such concept as a God, it is a subtle spirit, not an image of a man that so many have fixed in their minds. In essence, my religion consists of a humble admiration for this illimitable superior spirit that reveals itself in the slight details that we are able to perceive with our frail and feeble minds."

Intelligent design is a subset of the teleological argument which basically says that the Universe is too complex to have happened by "natural" processes. Then a conclusion is made that the cause must be a designer.
This argument has holes all over it, but also has one strength, which is just how friggin' complex things actually are.
That why I love studying complexity and my personal crusade is I think all people who love science should study it too!
BTW, this argument is the one that appeals most to me.
The qualifications I always make is that these things imply "something more" but give only minor clues as to what the "something more" might be. And they certainly don't exclude the natural phenomenon that we observe.
And this is why I criticize those who limit themselves to strict empiricism or fundamentalism.

I've always had an issue with "intelligent design".
I would have thought something like "obtuse design" or "a little bit stupid designer" or "whoops thats another mess waiting to happen design" would have been more appropriate.
I mean, who else would have set everything up but to allow the one thing that keeps everything alive to burn out after a period of time. Doh!
I reckon he must have skipped a couple of important lectures on his "Lets build a universe" course.
Makes sense then why his "son" was a carpenter, he must have inherited the same quality of brains!

Again, for natural selection to work, you have to have diversity. Natural selection, again, produces diversity slowly or even decreases it.
If you are going to be able to meaningfully defend your position, you have to understand it as deeply as you can. You also need to clearly know the gaps so that you're ready when someone questions them.

Baldfriede give an interesting example... I just shoot an idea and then will see what reaction it causes...
In the study of communications we have to study public reactions and audiences... there's a clear "feeling" on the silence of the reaction in the middle of a speach... how can you distinguish where a silence is a show of dissaprove, or is sadness, or is a show of hostility or missunderstanding...??? you can felt it and any priecher -a president, a musician, whoever who is over a stage- can feel it... how can all this dissarticulated people, as a mass, can give you a feeling and how can you distinguish when silence means something...??? well... I think that's the most fascinating thing that happen on the massive audience phenomena... that knowledge of "feeling" or sense, is there, and we don't need physical proof to that... so... I hope you understand my question here... It could be there a "spirit", a collective spirit that can be felt...??? not as a ghost or god.. but is there a non-physical feeling on it...???

What do think of this point...
"BTW, creationists use the fact that the fossil record is not smooth and continuous all the time as an argument against evolution. Punctuated equilibrium and genetic drift erase that argument."
I don't think that it's very scientific to say that those theories "erase" the whole argument (some gaps in the fossil record can be explained by other reasons).
