介绍了一个简单而稳健的相互作用物种生态的生物进化模型。该模型自组织进入临界稳态，并伴有各种规模的间歇性共同进化雪崩；即，它表现出“间断平衡”行为。这种协作进化比非合作场景要快得多，因为不涉及大的、协调的、因此不太可能的突变。
A simple and robust model of biological evolution of an ecology of interacting species is introduced. The model self-organizes into a critical steady state with intermittent coevolutionary avalanches of all sizes; i.e., it exhibits ''punctuated equilibrium'' behavior. This collaborative evolution is much faster than noncooperative scenarios since no large and coordinated, and hence prohibitively unlikely, mutations are involved.
