Recent work on the evolution of signaling systems provides a novel way of thinking about genetic information, where information is passed between genes in a regulatory network. I use examples from evolutionary developmental biology to show how information can be created in these networks and how it can be reused to produce rapid phenotypic change.
Thanks to others in the PSA Symposium: Rosa Chau, Peter Godfrey-Smith, Nicholas Shea, and Rory Smead, and especially to Peter for organizing it all. Thanks to Emily Parke for her many useful comments and to Lindley Darden for fixing my biology (any remaining errors are my own). This work was supported by an Australian Research Council Postdoctoral Fellowship.
