> with estimates of present-day human and faunal contamination both below 1%. Comparisons with present-day human populations²⁶ using ƒ3-statistics and D-statistics²⁷,²⁸ show high affinities to Native Americans (Extended Data Fig. 5). When projected into a principal component analysis with other ancient human individuals (Fig. 3c), DCP1 falls within a group of Ancient North Eurasian individuals from further east in Siberia, which includes the approximately 24 ka Mal’ta 1 and the approximately 17 ka Afontova Gora 3 individuals²⁹,³⁰. Both of these individuals are genetically closer to DCP1 than non-Ancient North Eurasian individuals when tested with D-statistics (Extended Data Fig. 6b), and all three show similar affinities to ancient Siberians and Native Americans with ƒ3-statistics and D-statistics
