A 2019 study by Haber et al. supports an African origin for haplogroup E (based on an analysis of the Y-chromosomal phylogenetic structure, haplogroup divergence times, and the recently discovered haplogroup D0 found in three Nigerians, an additional branch of the DE lineage diverging early from the D branch). The authors support an African origin for DE (parent haplogroup of E) with E and D0 also originating in Africa, along with the migration out of Africa of the three lineages (C, D and FT) that now form the vast majority of non-African Y chromosomes. The early divergence dates found in the study for DE, E, and D0 (all dated from about 71-76 kya), which are determined to predate the migration out-of-Africa of the ancestors of Eurasians (dated to ca. 50-60 kya), are also considered by the authors to support an African origin for those haplogroups.
