1. Phylogeny analysis is performed with phylip software package and encoding sequence of bdnf gene . the phylogeny trees have been drawn with three different methods ( maximum parsimony method , genetic distance method and maximum likelihood method ) , respectively . the analysis outcomes are not all consistent for the reason that it is closely related to the selected methods and the conservative level of the sequences
   采用不同的统计学分析方法，最大简约法( maximumparsimonymethod ) 、最大似然法( maximumlikelihoodmethod )和遗传距离法( geneticdistancemethod ) ，得到了物种系统发育进化树，但拓扑结构并不完全一致，这是可能是因为分子系统学研究与采用的分析方法和所选基因的保守程度即作为分子标记的可信度密切相关。
