Figure 4 in The Zagros Mountains acting as a natural barrier to gene flow in the Middle East: more evidence from the evolutionary history of spiny-tailed lizards (Uromasticinae: Saara)

Figure 4. Chronogram of diversification events based on two mtDNA (Cytb and 16S) and one nDNA (ACM4) genes for Uromasticinae, including the genera Saara and Uromastyx. Blue bars show 95% highest posterior density (HPD) intervals of the estimated node ages; values indicated on branches are mean node ages (Mya).
