## Figure 6.
Genealogical tree and skyline plots of coalescent statistics for sequences simulated
under episodic positive selection. There were 10,000 individuals in the simulation, and an advantageous mutation rate
μof 8 × 10_{a }^{-7 }per individual per generation with each mutation harboring a selective advantage s of 0.1. The tree shown represents the maximum posterior tree sampled over the course
of the MCMC analysis of the simulated data. Colors move from purple to red as fitness
increases. For coalescent statistics, TMRCA, diversity and N, solid lines represent mean values and gray outlines represent 95% credible intervals
across MCMC replicates. TMRCA, diversity and _{e}τNare measured in units of generations.
