Evolution of the per-site diversity for the worldwide human simulation (population C). Solid lines: neutral model; dashed lines: model with selection. Vertical dotted lines apply to the selection model and indicate when a strongly selected site (s > 0.075) went to fixation. Note that, for visual clarity, the time axis is scaled differently for different steps of the simulation.
