Figure 6

Posterior distributions of trait estimates for the LCA of living primates for a) body mass and b) brain mass. Histograms are plotted from a posterior distribution of ancestral state estimates obtained using uniform priors (prior range: -100 to +100) acceptance rates were within 20 to 40% (see methods). To ensure the chain fully explored the parameter space, we extended the MCMC run to 25 million iterations with a sampling interval of 1500.
