Extended Data Fig. 7: No effect of diversity on average speciation and extinction rates.
From: Loss of macroevolutionary species fitness explains the rise and fall of clades
Examples of the 800 total simulated diversity trajectories using a constant-birth death model with turnover (μ/λ) of 1, using λ = 1 and μ = 1 over 10 time units. The first 400 simulations (left) were conditioned on at least having 100 extinct tips, with 200 trajectories of clades in decline and 200 trajectories for clades that went extinct (fall). The second set of 400 simulations (right) were conditioned on clades that had from 20 to 40 tips, with 200 trajectories for clades in decline and 200 for clades that went extinct. 5 examples from each of the 200 simulations of the 4 categories above are shown.
