Original sentence: "D0" has also been named "D2", and former D (D-M174) has now also been termed "D1" due to this discovery.(2019) identified a haplogroup, termed "D0", in three Nigerians.Both D-CTS3946 and E lineages also exhibit the single-nucleotide polymorphism M168 which is present in all Y-chromosome haplogroups except A and B, as well as the YAP+ unique-event polymorphism, which is unique to Haplogroup DE.The "D0" haplogroup is outside M174, but belongs to the D lineage, shares 7 SNPs with it D-M174 that E lacks, and was determined to have diverged early from the D branch (near the D/E split) The authors considered several possibilities, including an African origin and Asian origin for the haplogroup, but in part because of the deep-rooting of haplogroup "D0", as well as recently calculated early divergence times for it and its parent haplogroup, DE, the authors conclude in favor of an African origin for D0 and DE, as well as for the common ancestor (now known as D-CTS3946 or "D") of D0 and D-M174
Edited sentence: (2019) identified a unique haplogroup, which those authors termed "D0", in three Nigerians.D0 was determined to have diverged relatively early from DE, but to still be a sibling of D-M174.Defined by the SNP A5580.2, D0 was found to be outside M174, but to nevertheless shares seven SNPs with D-M174 that were absent in E-M96.Haber et al.In part because of the deep-rooting of haplogroup D0, as well as recently calculated early divergence times for it and its grandparent haplogroup, DE, Haber et al.Like its only sibling, haplogroup E-M96, D-CTS3946 has the YAP+ unique-event polymorphism, which defines their parent, haplogroup DE.Subsequently, "D0" has been known as "D2", while the "old" D* (D-M174*) has been renamed "D1".concluded that both were African in origin, as well as their intermediary, D-CTS3946.considered several possible geographical origins, including an Africa and Asia
