 The authors conclude that this supports an Asian origin and may also explain signals of small percentages of Neanderthal DNA found in northern and some western Africans.A 2019 study by Haber et al.supports an African origin for haplogroup DE*, based in part on the discovery of haplogroup D0 found in three Nigerians (according to the authors a branch of the DE lineage near the DE split but on the D branch), as well as on an analysis of y-chromosomal phylogeny, recently calculated haplogroup divergence dates and evidence for ancestral Eurasians outside Africa.
