Estimated Divergence Times, with Migration
| Divergence Event | Ingroup (X) | Raw Estimates | Calibrated Estimates | ||
|---|---|---|---|---|---|
| Tdiv = 5.6 Mya | Tdiv = 6.5 Mya | Tdiv = 7.6 Mya | |||
| San (τKHEXS) | Yoruban | 0.91 (0.89–0.94) | 113 (110–116) | 131 (127–135) | 153 (149–157) |
| San (τKHEXS) | Bantu | 0.90 (0.88–0.93) | 111 (108–114) | 129 (126–133) | 151 (147–155) |
| AE (τKHEX) | Yoruban | 0.33 (0.31–0.34) | 40 (38–42) | 47 (44–49) | 55 (51–57) |

Raw and calibrated estimates for the San (τKHEXS) and African-Eurasian (AE) (τKHEX) divergence times. Separate results are shown for the Yoruban and Bantu representatives of the African ingroup population X. In all cases, a migration band between the San and the African ingroup X was included in the model. Raw estimates (mean and 95% Bayesian credible intervals) are given in units of expected mutations per site × 10−4. Calibrated estimates are given in thousands of years (kya), for three different human-chimpanzee calibrations (Tdiv = {5.6, 6.5, 7.6} Mya).
