Extended Data Figure 3: Number of angiosperm genera that originated during specified geological timespans.

Column with three colours shows the number of woody (grey), herbaceous (yellow) and mixed genera (light blue) that originated within a specific geological timespan. Number of woody genera, n = 995; number of herbaceous genera, n = 1,569; mixed genera (genera with both woody and herbaceous species), n = 101. The dashed line indicates the accumulated percentage of genera that have originated since the Early Cretaceous. Global temperature changes that have occurred since the Palaeogene are shown by the red curve (from ref. 39; reprinted with permission from AAAS). The x axis indicates the geological period and time in millions of years. The left y axis shows the total number of genera that have originated by any given time period; the right y-axis represents the accumulated percentage of genera that originated within a geological time period.
