Discrete trait Bayesian tree. This tree was selected from the set of 12 discrete trait trees as having parameter estimates most similar to the mean estimates from all 12 trees. Colors represent locations. The location legend is in the upper left corner. The location codes are the same as in Additional file 5: Table S3. The numbers at the nodes are the posterior probabilities. The time scale is in calendar years. Sequences are identified as the two letter location code, accession number and the last two digits of the year in which the sample was collected. The letters A and B mark the locations of the MRCA node for the Pakistan clade and KF041236, respectively
