Extended Data Fig. 3: Proportions of species originating versus going extinct.
From: Impacts of speciation and extinction measured by an evolutionary decay clock
1-Myr increments from 600 to 0 Ma with a threshold of 30% species entry/exit threshold, grey square. This threshold highlights the top 66 times of turnover from 222 total turnover times identified among 600 times included in the analysis. Red, mass extinctions; blue, mass radiations; magenta, mixed mass extinction–radiations.
