Figure 2.
Potential examples of revisions in topology necessitated by the discovery of new mutations and new samples with intermediate haplogroups. Haplogroup nomenclature systems are shown to the right of the tree. (A) The G and H haplogroups are as shown in Figure1. (B) Case of a newly discovered marker that joins haplogroups within haplogroup G. (C) Newly discovered mutation (μ) that splits clades within haplogroup G. (D) Case of a newly discovered sample with the derived state at M52 and the ancestral state at M69. Names shown in boxes indicate haplogroup names that require changes from those shown in A. Dotted lines indicate newly created lineages.
