The STRUCTURE results concerning the averaged proportions of membership (Q) are shown in Table 1. They were obtained in relation to the predefined reference populations of the HGDP-CEPH panel, and partitioned in K=2 (America and not-America) and in K=5 (Africa, Europe-Middle East (ME)-Central Asia (CA), East Asia, Oceania and America). In general, Peruvian subpopulations present a high proportion of autochthonous American ancestry 90.5%
) and heterogeneous levels of non-autochthonous admixture. The values of Eurasian (Europe, ME, CA) ancestry proportions are displayed in Figure 4. In Table 1, the localities of San Marcos, Characato, Cajamarca, Chogo, Lambayeque and Lima presented the highest average proportions of membership (31.2%, 24.4%, 20.5%, 14.6%, 14.5% and 14.3%, respectively) to the Eurasian region (Europe, ME, CA). Intermediate levels of Eurasian ancestry were associated with the localities of Lamas, Ayacucho and Huancayo (8.7%, 8.1% and 6.1%, respectively). These Peruvian localities associated with a partial genomic ancestry derived from Europe, Middle East and Central Asia also present small genomic ancestry proportions from Africa (<3.4%). It is interesting to note that some ancestry proportions (Table 1) are more related to the East Asia region in Chachapoyas (8.2%), Mollebaya (8%) and Iquitos (6%), but Pucallpa presents 5.2% East Asian ancestry together with 9% from Oceania and 8% from Europe, Middle East, Central Asia. A large East Asian contribution is likely associated with recent post-Columbian migration into these areas, as indicated by recent historical reports.18 Because our sampling was anonymous and collected without genealogical information, East Asian ancestry for individual samples cannot be verified.
LIMA IS ONLY 14.3% EUROPEAN!! No wonder the city in videos looks pure amerindian
