We have published an invited headline review in the Journal of the Royal Society Interface on the Construction, comparison and evolution of networks in life sciences and other disciplines. Our paper describes how biological networks change over time – in relatively short scales like during signal transduction and in relatively long scales like during development and evolution. We give a comprehensive overview about existing methods for analyzing such network changes. Moreover, we take a survey across non-biological sciences to explore how they investigate network changes. Our survey includes also some entertaining examples on the evolution of cooking recipes and the Marvel Universe.
