Regarding the origin of haplogroup D0/D2
You seem to have made edits to several articles on claes of haplogrou D editing the map to depict an speculative route depicting and Asian origin of the newly discovered haplogroup D0 (also termed D2) — however, no such route is proposed in the scientific research as it currently exists. I undid these edits. The origin of D0/D2 is not currently known, and no researchers have, as yet, put forward an Asian origin hypothesis for the haplogroup. An African origin and divergence for D0 was proposed by Haber et al. 2019, not only based on the presence of D0 in Nigeria, but also on its calculated divergence date (and those of other DE lineages, as well as other evidence), which was determined to predate the likely date of the migration of ancestral Eurasians out of Africa. It is true that D0/D2 has also been found in the Middle East, including a relatively basal branch in Syria (though dated to ca. 26,000 years ago, much later than the migration out of Africa). But this is not necessarily proof or evidence of an Asian origin (especially considering the divergence dates). And, in population genetics, the current distributions of haplogroups is not always indicative of their original distribution or their origins (as mentioned in the notes, It is unknown where the extant D2/D0 branches originally came from or how they got to their current locations) Adding interpretations not made in sources would violate wikipedia rules against POV see: WP:POV and/or original research, see: WP:OR. Until further research/information is available, it would seem best to avoid including theories on the origins of haplogroups in edits (until one can cite a reliable source that proposes those theories).Skllagyook (talk) 21:15, 2 September 2019 (UTC)

I just saw your most recent edit notes. It seems (and I would agree) that it might be best currently to leave in the map that does not include D0/D2. On the other hand, the map depicting an African origin is in keeping with the recent research of the Haber et al. study, whose research is the most recent expert opinion on the haplogroup's origin (Haber et al. also suggests that the reported DE in Tibet might not truly be DE, so that aspect of the map is in keeping with the research also). Perhaps the page could use either the map without D0/D2, or alternately it could use the African origin map (since that scenario/theory seems to be the best supported currently) but perhaps with a caption explaining that it is one current theory, perhaps saying something along the lines of "The migration route and divergence of the D lineages according to Haber et al. 2019".
