Paul Andersen explains how biology is ordered in the hierarchy of life. He first of all describes how emergent properties appear as you move to more inclusive systems. The then describes life at the following levels; atom, molecule,...

Long before there were strip malls, skyscrapers, and combination Pizza Hut/Taco Bells, nature had its own architects: all kinds of creatures create all kinds of structures for living, raising offspring, or maybe just the occasional...
