Figure 1. Phylogeny, geographic distributions, sequence divergences and divergence dates of the six bathyergid genera.

(A) Phylogeny of all six bathyergid genera based on the cytochrome b data. Values above nodes represent posterior probability values derived from the Bayesian analysis in BEAST and MrBayes respectively, while values below nodes indicate bootstrap values derived after Maximum Likelihood analysis in RAxML. A “-” indicates that the node was not retrieved by the particular analysis. The geographic distribution of these genera across sub-Saharan Africa is portrayed in (B) with the uncorrected sequence divergences (%) at the various nodes shown in (C). The divergence date estimates (in Mya) for each node is indicated within the black circles in (D).
