Order emerges in simple systems as well. Turing was fascinated by the emergent order of bi-stable chemical reactions, the moving wave-fronts of reaction inside a bounded space. Not that there aren't puzzles a-plenty here. Why things like energy minimisation make water freeze in complex regular shapes which presents as "how do the limbs know to take that pattern" delight me. I kind of felt ok with "just because" but I realize that's not really an answer.
