Quotes from essays, very impressive. Which creationist website did you find that on? Curious - as I know you never read the whole essay,
would you like to? Gould was a great author. I saw him give a talk once - on the rise of creationism in America. It was precious when a creationist student attempted to undermine Gould's thesis (that creationism is garbage) by claiming during the Q&A that Gould had misrepresented a passage from Genesis. Gould promptly pulled out the Gideons bible that he had taken from his hotel room, opened to the passage in question, and put the young creationist in his place.
Anyway, back to the Cambrian "explosion" of 5 million years (Threepwood was likely conflating/confusing the Precambian and the Cambrian and who knows what else- he does that a lot). 5 million years is a long time (and we will not even bring up the lengthy Precambrian and such). Hardy archaea can reproduce every 20 minutes or so. Let's say every hour. That is 8,760,000,000 'generations' in 1 million years. If an organism can only reproduce 2 a year, that is 2,000,000 generations - each generation experiencing the changes in their genomes that introduce diversity. Evidence shows that by the Cambrian, of course, we had multicellular eukaryotes and such already.
Given your rich and in-depth understanding of the history of the world and science, tell me how long it
should have taken to generate the diversity preserved for us in the Burgess Shale and other sites during and prior tot he Cambrian 'explosion.'
Supported with evidence, of course.
