Figure 2From: Population expansion in the North African Late Pleistocene signalled by mitochondrial DNA haplogroup U6BSPs of median effective population size through time for U6 (A) and U5 (B), using the internal calibration of mutation rate. The black line represents the posterior effective population size through time. The blue region is the 95% highest posterior density interval for effective population size at any time point. Effective population size is plotted on a log scale. A generation time of 25 years was assumed.Back to article page
