The Dual Phase Evolution Framework for Understanding Evolutionary Dynamics in Complex Adaptive Systems

Abstract

Evidence from several fields suggests that dual phase evolution (DPE) may account for distinctive features associated with complex adaptive systems. Here, we review empirical and theoretical evidence for DPE in natural systems and examine the relationship of DPE to self-organized criticality and adaptive cycles. A general model for DPE in networks is outlined, with preliminary data illustrating the emergence of phase changes. DUAL PHASE EVOLUTION ExamplesEvidence from several fields suggests that phase changes in landscape connectivity form a powerful agent of evolutionary change and innovation. Disasters often mediate long-term changes in the composition of ecological communities, with 135
