Abstract

We compare the "patterns of mutation" in biological and technological networks. Negative selection at central nodes in biological networks has been widely reported; however, we show technological networks have an opposite trend. This suggests a potential contrast: biological evolution involves random tinkering, whereas man-made systems change according to rational planning.
