Extended Data Fig. 4: F4-ratio test for the Anzick-1-related ancestry.
From: Genomic history of coastal societies from eastern South America
Indirect estimates of Anzick-1-related ancestry proportions setting Los Rieles_11900BP and Lauricocha_8600BP as the early Holocene reference individuals with the highest and lowest amount of Anzick-1-related ancestry, respectively. ‘Test’ refers to the ancient Native American individuals/groups included in the calculation and highlighted in bold are samples from Brazil. The alpha values were calculated using the f4-ratio formula reported in the Methods section. The size of the points represents the number of SNPs used to compute comparisons (at least 400,000 SNPs). Bars represent f4-ratio ± 3 standard errors for all tests. The F4 ratio estimates are sorted from the highest to the lowest alpha values. The Lapa do Santo_9600BP group (purple dot) shows a significantly higher Anzick-1-related ancestry than Lauricocha_8600BP.
