Simplified Human mtDNA Phylogeny

The L0 and L1′5 branches are highlighted in light green and tan, respectively. The branches are made up of haplogroups L0–L6 which, in their turn, are divided into clades. Khoisan and non-Khoisan clades are shown in blue and purple, respectively. Clades involved in the African exodus are shown in pink. A time scale is given on the left. Approximate time periods for the beginning of African LSA modernization, appearance of African LSA sites, and solidization of LSA throughout Africa are shown by increasing colors densities. For a more detailed phylogeny, see Figure S1.
