"...in particular DNA from ancient individuals like Mota found in present-day Ethiopia, may increase precision in identifying ancient ancestral differences between Ethiopians using these techniques.
Under the “Ethiopia-external” analysis, GLOBETROTTER infers admixture in 69 out of 78 Ethiopian clusters (
Fig 3b, Extended Table 5),
with results indicating intermixing between a source represented by (a) Sub Saharan African groups (often including Mota) and another source represented by (b) W.Eurasian (related primarily to present-day Saudis, Yemenites and Iranians;
Fig 1b), Egyptian and/or N.African groups (
Fig 3b, Fig S9, Extended Table 5). Notably, Somalia differs among clusters in that it acts as a surrogate to source (a) in north/northeastern clusters with higher amounts of inferred ancestry related to Egyptian groups (type “a” clusters), while it acts as a surrogate to source (b) in west/southwest clusters with higher amounts of inferred ancestry related to East/West Sub-Saharan Africa (type “b” clusters) (
Fig 3, Fig S9b-c, Table S10, Appendix B)."
