The yDNA DE* was found in two Tibetans in China as well as in one African. Its existence in China is probably related to the existence of the early Homo Sapiens population (“Early presence of Homo sapiens in Southeast Asia by 86–68 kyr at Tam Pà Ling, Northern Laos” nature.com/articles/s41467-023-38715-y), whose fossil was reported to be unadmixed with archaic humans (which include Neanderthals and Denisovans).

“Human genetic history on the Tibetan Plateau in the past 5100 years” reported the percentage, characteristic of yDNA DE*-related ancestry in "Human population history at the crossroads of East and Southeast Asia since 11,000 years ago", from the ancient yDNA K2a* Ust’-Ishim.

Nonetheless, in “Genomic insights into the origin of farming in the ancient Near East”, the so-called Basal Ancestry (of African type) was defined as separating prior to the split of ancestries, included in Ust’-Ishim. If yDNA DE*-related ancestry in Ust’-Ishim, defined by “Human genetic history on the Tibetan Plateau in the past 5100 years” and "Human population history at the crossroads of East and Southeast Asia since 11,000 years ago", is taken into account, it appears that only yDNA CT(x DE,xCF) (yDNA CT*) member, an ancestor of yDNA DE and yDNA CF, could be a bearer of the real Basal Ancestry (of African type), which would be thought of as actually separating prior to the split of Ust’-Ishim ancestries (including yDNA DE*-related ancestry in Ust’-Ishim, defined by “Human genetic history on the Tibetan Plateau in the past 5100 years” and "Human population history at the crossroads of East and Southeast Asia since 11,000 years ago"). When the DE*-related ancestry is in Ust’-Ishim, then any D-M174 bearer and any E-M96 bearer should have at least a certain connection to the Ust’-Ishim’s layer of ancient populations.
