Thoughts on evolution #2

More from an e-mail discussing evolution:

I have yet to hear of any explanation of this that doesn't rise above the level of what I call "comic book science." And believe me, I know all about comic book science. Chemicals + energy = superpowers. A teenager is attending a science exhibit. Radiation is suddenly released just as a spider bites the young man. Energy (radiation) + chemicals (spider venom) = Spider Man!

Compare that to a "scientific" explanation of how billions of pieces of computer code (DNA) were added to existing creatures during the Cambrian explosion.

"Tectonic events made mountains as well as earthquakes which affected many species (Nash). These could have forced tidal waves which would add to the circulation of the water in the oceans and alter the chemistry over a large range. This may have been a key point in accelerated evolution, possibly creating scenarios that added oxygen to the water. When there was little oxygen in the atmosphere multicellular life could not expand but as algae started to produce more oxygen through photosynthesis, bacteria then used the oxygen and produced greenhouse gasses which warmed the earth encouraging the growth of life (Nash). As the algae built up on the floors of the oceans due to erosion it was proposed that water could not circulate as well, possibly promoting life to evolve rapidly during the Cambrian period (Nash)."

Blah, blah, blah. That would have been perfectly acceptable in Darwin's day because we didn't know any better. I would go so far as to say that in the light of our current level of understanding in the life sciences, that the preceding quote hardly qualifies as science.

Millions and billions of biological computer code would have had to be added to existing organisms over a relatively short period of time. How did this happen?
