From: Human population history revealed by a supertree approach

Figure 1

(a) Semistrict consensus supertree of 186 human populations (outgroups not shown) based on the representative dataset and parameter set 1.A of the sensitivity analysis (all data partitions were weighted equally and all sources were considered rooted). SOUTH BANTU = Ndebele + Swati + Xhosa + Zulu (often occurred as a composite population in the source trees); AUSTRALIAN consists of Australian Aboriginal populations of unspecified ethnic origin. The color code corresponds to the recovered monophyletic or paraphyletic groups of populations. The wildcard taxa (Qatari, Andamanese, Malagasy, Dayak Ngaju) are displayed (in gray) in the most basal of all positions they acquired when included into the dataset, but were not taken into account when assessing node and group support. The circles indicate presence of the nodes in the strict (white) and semistrict (gray) consensus of 16 supertrees derived from the sensitivity analysis (a circle is absent if the respective node is absent even in the semistrict consensus). The analysis space plots (square grids) describe presence of the selected clades/groups in the supertree under individual parameter sets as either: a monophyletic clade (white); a paraphyletic group or an unresolved section compatible with monophyly or paraphyly (gray); a polyphyletic assemblage (black). Completely white grids (=the group present under all parameter sets) are substituted by small white squares. (b, c) Alternative topology for the N African–W Eurasian assemblage and the Sahul–Oceanian clade as recovered in parameter set 2.C. (d) Alternative topology for the E Asia clade as recovered in parameter sets 4.A–4.D. The nodes where the alternative topologies (b, c, d) begin in the supertree 1.A (a) are denoted by asterisks. (e) Geographic locations of 186 human populations plotted on the world map using QGIS v.2.8 (the color code corresponds to the trees).
