Many physical, biologial and social systems can be represented as networks. Thinking of real systems in this way can often lead to novel and useful insights. These mathematical abstractions help us to visualize complex systems, to find useful measures of complexity and eventually develop computational models of reality. Evolution of Networks, led by CSIC Tenured Scientist Sergi Valverde, studies natural and artificial networks in the search for universal evolutionary principles. We are interested in the role played by emergence, convergence and environmental fluctuations in the origin of evolutionary innovations, and how the pattern and process of evolution differs when traits are learned rather than transmitted genetically.  The group brings expertise in complex systems, complex networks, and theoretical ecology. An unique approach of our lab is the complex networks perspective of the evolution of culture, which we have pionnered (see our review paper here). We also develop systematic ways to recollect and analyse the rich fossil record of innovations.”
