@farmerman,
Firstly, yes. Thirty million years is not very long on the geologic time-scale as you yourself point out when you assert it took hundreds of millions of years to form the complexity we now see. My argument for the cambrian explosion is well-founded in the fossil record, which, before even being aware of the cambrian explosion, Darwin himself admitted was a large problem in his theory. He assumed that as time went on, the fossil record would fill itself in. I repeat my argument that it has not. That all major animal groups appear at the same time, fully formed. I will concede that there were shells and basic fossils before, but none of them with anything close to the complexity seen during the Cambrian period - which IS when the Cambrian Explosion took place. That is, if you are willing to accept archaeology as a valid field of study.
I will also repeat that the intermediate stages, with the characteristics that are necessary to make them intermediate stages, would stand virtually no chance of surviving. The idea of macroevolution is that each species becomes adapted to its method of survival and that only the strongest survive(natural selection, which is itself a misnomer as the 'natural' which means without intelligent interference precludes any kind of selection or choice). This principal is the very downfall of the intermediate stages. The intermediate stages lack all the abilities of either creature that they are related to. So again, a lizard to a bird. What good would non-functional wings be to a lizard? None. It would only destroy the lizard's chance of surviving because it can no longer function as a lizard and cannot yet function as a bird.
Another problem is that macroevolution must be directional. If it were not, the lizard may get half way to being a bird and then instead, start going to go back to being a fish.
Additionally, my beliefs on this topic are slave to my belief - well founded in science and logic - that the universe was created, though that's in another thread if you care to see it.
It is important to note that - as far as I am aware - there is nothing published in any reputable scientific journals or books supporting the natural systems by which macroevolution would take place. If there are any, then please post a link or something.
Michael Denton writes "at a molecular level there is no trace of the evolutionary transition from fish to amphibian to reptile to mammal. So amphibia, always traditionally considered intermediate between fish and other terrestrial vertebrates, are in molecular terms as far from fish as any group of reptiles or mammals! To those well acquainted with the traditional picture of vertebrate evolution the result is truly astonishing."
You may say 'so what?' to the argument of the dissimilarity on the molecular level, but if evolution were true, the molecular level should clearly show genetic similarities between these stages.
Additionally, fossils cannot establish an ancestral relationship. Michael Denton also points out that roughly 99% of a creature's genetic information is in its soft tissue, which is not preserved in the fossils. Simply put, we don't know what these early creatures looked like, what their genetic codes would have been, or anything of the sort! It's entirely open to individual interpretation.
As for your assertion that there are in fact many intermediate links, well I simply ask you provide evidence for it. You claim that the cambrian explosion did not actually take place during the Cambrian period, though it is a nearly agreed upon fact. You say every singly phyla has evidence of intermediate stages, please back up your claim as you seem to be ridiculing me for not doing so.
Also, in regards to forming proteins, NO high school lab has done this. No scientist has done this. Amino acids have been formed, yes. Miller-Urey and one more recent experiment have demonstrated this. But the concentration of chemicals is such that it would have been impossible in the early atmosphere. The experiments to which I refer also produced a bad ratio of left and right handed molecules.
There are quite simply no natural laws that can produce specified complexity, such as is required for life. The laws of nature, when uninfluenced, bring disorder.
The simplest life contains the equivalent number of letters(ATCG in the genetic language) to 1000 volumes of the Encyclopedia britannica.
As I have said, no natural laws are known that can account for specified complexity and therefore no natural laws that can account for this vast accumulation of knowledge.
There are 2 types of causes, natural and intelligent.
If natural causes cannot account for the origin of life, then the only logical answer is intelligence.
Basically, I see this entire argument as moot because it presupposes that there is no supernatural force, even though a supernatural force in some shape or another is the only logical explanation for the universe being here. Evolution tries to explain a problem that, for all intensive purposes, does not exist. That problem is 'how did life form without intelligent design?'
