For each trait, the effective sample size of the likelihood (natural log) of models in the MCMC, the mean and standard deviation of the number of Θ shifts per model in the posterior distribution, the proportion of models with an optimum shift on the Homo tip, the rank of the Homo tip amongst all branches in the tree in terms most optimum shifts on the given branch, the mean and standard deviation of all shifts on the Homo tip, and the proportion of those shifts that are positive. Optimum shift values represent log10 transformed data.
