A comparative history of innovations in regulatory regions and genes. Each panel shows data for the frequency of regulatory innovations near genes in a different GO category (panel title) as well as the frequency of genic innovations for that GO category. Each data point for regulatory innovations (red circle) represents the percent of regulatory innovations appearing on a branch in the human lineage that are associated with a gene annotated with the given GO category. Each data point for protein-coding genes (red x) represents the percent of protein-coding genes appearing on a branch that are associated with the given GO category. The time associated with each data point is as described in Fig. 1.
