Fig. 2

Outcomes of inferring the existence and position of a selective shift from codon data simulated under a non-equilibrium mutation-selection model in which amino acid fitnesses may change at speciation events. Shaded areas give the proportion of simulations (\(n=20\)) in each of 6 treatment blocks that produced each outcome. From top: inferences returning only the position of the correct branch; inferences returning the correct branch plus an additional incorrect branch; inferences returning only one or more incorrect branches; inferences with opimisation failure; and inferences returning no branches. The treatments are divided by codon sequence length and number of taxa in the simulated birth-death tree
