“Life’s branching organisms create new niches faster than new organisms arise to live in those new niches. The biosphere explodes in diversity. Organisms “make a living” with one another: my refuse is your food. My solid surface affords a place on which you can crawl or run. Reindeer run on the permafrost. The permafrost now melts, the reindeer stagger, the Lapps lose their herds after thousands of years of a stable lifestyle. We all make our livings with one another.”

“Deep in the chaotic regime, slight changes in structure almost always cause vast changes in behavior. Complex controllable behavior seems precluded.”
