Mitochondrial Evolutionary Analysis. Evolutionary branch length, also known as genetic variation or evolutionary distance, represents the degree of branch variation; the shorter branch length represents a smaller difference and closer evolutionary distance. Distance scale: unit length of numerical differences between organisms or sequences, equivalent to the scale of the evolutionary tree. Bootstrap value is marked at the node position and used to evaluate the credibility of the branch
