What is the mechanism through which fractals arise in plants and animals?
because fractals are emergent structures created by simple rules, as are many biological structures. The same kind of simple recursive signals that lead to fractals are simple enough to be stumbled on by biological evolution and are effective ways to deal with the scaling problems created by the square cube law.
