Line Plot from Scientific Research

We used HapNe-LD to estimate the changes in effective population size ( N e ) over time of Yamnaya ancestors. We carried out the computation separately for the individuals from the earlier 300 years of our sampling and the later 300 years; shading shows confidence intervals (dark, 50%; light, 95%). Jointly displaying these two trajectories reveals an extraordinary population expansion at 3642–3374 bc (intersection of 95% confidence intervals for the two analyses for the minimum), from when the effective size is a few thousand to an order of magnitude larger. The offset on the x axis is due to the difference in sampling time between the two groups.
