Figure 2. Inferred population history.

Figure 2

Population splits and effective population sizes (Ne) during great ape evolution. Split times (dark brown) and divergence times (light brown) are plotted as a function of divergence (d) on the bottom and time on top. Time is estimated using a single mutation rate (μ) of 1·10−9 mut/(bp·year). The ancestral and current effective population sizes are also estimated using this mutation rate. The results from several methods used to estimate Ne, (COALHMM, ILS COALHMM, PSMC and ABC are colored in orange, purple, blue and green respectively). The chimpanzee split times are estimated using the ABC method. The x-axis is rescaled for divergences larger than 2·10−3 to provide more resolution in recent splits. All the values used in this figure can be found in Table S5.
