Figure 4
Genetic affinity (f4) between modern populations of the Caucasus and pairs of contemporaneous ancient populations. The numbers show the significant Z-values of f4 (i.e. |Z|> 3). Z < 0 indicates higher genetic affinity between the modern population and the ancient population at left of the pair on the Y-axis, while Z > 0 indicates higher genetic affinity between the modern population and the ancient population at right. Asterisk indicates disagreement between the genetic affinity and geographic proximity based on the least-cost distance.
