But the metaphor Michael is calling on, Carol, as I see it is "normal
science" is the incremental, gradual adaptation of a species to its niche,
and remaining much the same for millions of years, and on the other hand,
when a species is under real pressure, you get exactly the process Kuhn
describes in science: rapid diversification and die-outs, with a distinctly
new species species emerging at the end. It's called "punctuated evolutuion"
isn't it?
I find the idea of a formation perfecting itself into extinction attractive.
As to "Intelligent design" - this has nothing to do with proof or disproof,
Carol, but Faith.
