Below is a plot for a higher-resolution K = 8 admixture analysis that includes a Chinchorro mummy sample from Chile dated to 3972–3806 BC. This analysis uses a much larger number of transversion SNPs for all samples than my earlier admixture analyses. While most of my admixture analyses have used 1,067 transversion SNPs for the Chinchorro sample, and my previous high-resolution admixture analyses used 2,055 transversion SNPs for the sample, this analysis uses 26,982 transversion SNPs for the sample.
Here are the new admixture percentages for the Chinchorro sample:
0.00%
27.12%
13.13%
0.00%
0.00%
0.00%
58.45%
1.30%
The sum of the non-Amerindian component percentages in this analysis is 41.55%, which is a bit higher than the sums for the preceding analyses.
The presence of the light blue component in the Chinchorro sample excludes unadmixed Mesolithic European hunter-gatherers, and also Mal’ta-related populations as sources of its European admixture.
