Phase transition in cellular random Boolean nets
Kauffman's NK Boolean networks. "Because the regulatory structures at the edge of chaos (K ~ 2) ensure both stability [robustness] and evolutionary improvements [evolvability], they could provide the background conditions for an evolution of genetic cybernetic systems."
