Below is a plot for a high-resolution K = 5 admixture analysis that includes a Chinchorro mummy sample from Chile dated to 3972–3806 BC.
Here are the admixture percentages for the Chinchorro sample:
Here the Chinchorro sample has a lot of the blue component, a tiny amount of the yellow component, and some of the purple component. The pre-LGM European samples also have a lot of the blue component, and smaller amounts of the yellow and purple components.
Note that the sum of the non-Amerindian component percentages in this analysis, 32.13%, is very close to the corresponding sum for the K = 4 analysis, 31.66%.
