Re: [xmca] Units of Scientiic Achievement

Andy, I don't think the analogy with evolution of biological species can really work.

There is tremendous kinship between us and chimps; and the commonalities among us, chimps and our common ancestors is unlike any commonality that you could point to between Ptolomaic and Copernican astronomy, or "chemistry" pre/post oxygenation, etc.

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.
