Bacterial Growth in Stressed Environments
Trees and ferns often grow in fractal forms. Bacteria colonies can, too. But how?
|Are these patterns the result of simple physical processes, or
do they represent self-organization and communication on many levels?|
|Certainly, different causes can produce the same effect: the existence of fractal
bacteria colonies does not favor one mechanism over another.|
|But note 3 billion years of evolution have given Nature
ample opportunity to discover and exploit purely physical processes.|
