The phylogeny tree constructed from mitochondrial genome sequences. Note: The numbers above the branches are the Bayesian posterior probabilities and the numbers below the branches are the bootstrap proportions derived from the parsimony analysis. For the Bayesian analysis, the best substitute model GTR + I + G was used, and 20 million generations were executed. One sampled tree from the last 20,000 generations, which matched the tree with all clades/haplogroups, was used for the Bayesian MCMC by BEAST. The time to a most recent common ancestor (TMRCA) for clades/haplogroups was marked along with the node
