View on the West Eurasian mtDNA phylogeny through the narrow window 4527–4954. Boxed letters designate haplogroups and rCRS (revised Cambridge Reference Sequence) and α-γ are specific lineages. Each bar indicates a mutation, which is numbered when it occurred within the window. All mutations are transitions unless suffixed by a letter in case of a transversion (to T or C) or a deletion (d). Nomenclature of haplogroup H2 and H2a is as in .
