Adaptive systems frequently incorporate complex structures which can arise spontaneously and which may be nonadaptive in the evolutionary sense. We give examples from phase transition and fractal growth to develop the themes of cooperative phenomena and pattern formation. We discuss RNA interference and transcriptional gene regulation networks, where a major part of the topological properties can be accounted for by mere combinatorics. A discussion of ensemble approaches to biological systems and measures of complexity is presented, and a connection is established between complexity and fitness.
自适应系统常常包含复杂的结构，这些结构可能会自发出现，并且在进化意义上可能是非适应性的。我们给出相变和分形生长的例子来展开合作现象和模式形成的主题。我们讨论RNA干扰和转录基因调控网络，其中大部分拓扑特性仅通过组合学就能解释。本文还讨论了生物系统的系综方法和复杂性度量，并建立了复杂性与适应性之间的联系。
