We have reorganized the manuscript mainly by adding a new “Material and Method” section where discussions on branch length, statistical resampling, meaning and choice of K, etc., were given. The original Figure 1 was deleted with some related points explained in the text accompanying the original Figure 2. All figure captions have been rewritten for clarity.
I have noted some lack of scientific rigor according to: many wrong taxonomic names and typos, scarce figure legends, few comments about the missing branch lengths or bootstraps (! ), redundancy in text and figures and fragments which are really difficult to understand. Authors should pay attention to language, explanations and text organization.
