Extended Data Figure 1 : A decrease in Neanderthal ancestry in the last 45,000 years.

From: The genetic history of Ice Age Europe

Extended Data Figure 1

This is similar to Fig. 2, except we use ancestry estimates from rates of alleles matching to Neanderthal rather than f4-ratios, as described in Supplementary Information section 3. The least-squares fit excludes Oase1 (as an outlier with recent Neanderthal ancestry) and Europeans (known to have reduced Neanderthal ancestry). The regression slope is significantly negative (P = 0.00004, Extended Data Table 3).
