Taming the late Quaternary phylogeography of the Eurasiatic wild ass through ancient and modern DNA
Fig 3
Phylogenetic tree of the mitochondrial control region of the Eurasiatic wild ass constructed through BEAST analysis.
The corresponding E. asinus DNA region was used as an outgroup. The estimated median height of the nodes is indicated in red, in kiloyears (kyears), and the thickness of the lines is proportional to the posterior clade probability (the scale is represented). The mean substitution rate averaged across the whole tree is 8.5 E-8 substitutions per site per million years (95% HPD interval: 2.1–18.8 E-8). The colors of the box surrounding each individual sequence follow the same convention as in the sPCA analysis displayed in Fig 1. The names of the deduced clades are indicated in italics. The symbols following each sequence name indicated the origin of the sample (Square: Archeological; Triangle: Historical; Circle: Modern), and the red circles indicate the modern dziggetais (see text). For an enlarged representation of the tree containing the names of the sequences, the 95% HPD of the node height values, the posterior probabilities of the nodes and their bootstrap values by ML analysis, see Fig H in S2 File.
