Rift Valley fever virus M segment maximum a posteriori clade credibility tree, MCMC chain length 9.0 × 107 steps, 2.25 × 106 steps (25%) removed as burn-in. Posterior support values (highest posterior density, HPD) are indicated as integers (i.e., 100% support = 1.0) above each node respectively. The calculated mean times to the most recent common ancestor (TMRCA) are indicated below each respective node and are enumerated as years before the collection date of the last outbreak specimen (May, 2007).
