We investigated the mutually supporting role of chaotic activity and evolving structure in a complex network. An initially randomly coupled network with chaotic activation is adaptively rewired according to dynamic coherence between its units. The evolving network reaches a small-world structure. Meanwhile, collective network activity tends to an intermittent dynamic clustering regime. Spontaneous chaotic activity and adaptively evolving structure jointly enhance signal propagation capacity.
