a–c, Correlation between observed pairwise genetic distances between demes as inferred by EEMS16 and Haversine geographic distances prior to ~3,000 BCE (a), during the third millennium BCE (b) and after ~2,000 BCE (c). d, Isolation-by-distance patterns through time inferred from autosomal (red) and X-chromosomal (blue) variation. e–f, Bayesian Skyline plots reconstructed from mtDNA (e) and Y-chromosomal variation (f). The third millennium BCE is highlighted in blue. The red line indicates the median of the 95% confidence range, shown in grey.
