Extended Data Fig. 4: Formal test for temporal genetic changes in the Caucasus region.
From: The rise and transformation of Bronze Age pastoralists in the Caucasus
a, f4-statistic tests where X denotes Anatolia N, EHG, or Iran_N and b, where X denotes CHG, EHG, and Iran_N, and Test denotes various genetic groups from the Caucasus and Steppe clusters on the y axis. Significant Z-scores (|Z| > 3) are highlighted in orange and error bars indicate ± 3 s.e. and were calculated using a weighted block jackknife across all autosomes on the 1,240,000 panel (nSNPs = 1,150,639) and a block size of 5 Mb.
