Posterior chitinase date distribution across nodes with varied model selection. Models: 10, birth-death prior and uncorrelated gamma relaxed clock model (red); 14, birth-death prior and lognormal autocorrelated relaxed clock model (blue); 2, uniform prior and lognormal autocorrelated relaxed clock model (green); and 6, and uniform prior and uncorrelated gamma relaxed clock model (purple)
