    David Brin’s excellent sci-fi novel Kiln People employed the colorful metaphor that the caterpillar, rather than metamorphosing into a butterfly, is more accurately devoured from within by the new organism.  But I guess that was more artistic license than it was actual science.

    well, I wouldn’t use the term ‘from scratch’ as a scientist, it’s inefficient.
    from genetic potential maybe? or from the ether?

    This most excellent post only needs one addition: “Cousin Caterpillar,” by the Incredible String Band.
