| Abstract: | This paper deals with the phylogenetic relationship, the speciation andthe place of the origin of the subgenus Eospalax, genus Myospalax. Theconclusions are as follows: 1. According to the analysis of the characters, phylogenetic cladogram has been presensed. We have found that Myospalax fontanieriis the former of first speciation, but Myospalax smithi and Myospalaxrothschildi are the formers of second speciation. 2. Change of envirment and competition with each other for thefavourable living enviroment make the population speciate. 3. We have considered that the place of the origin of the subgenusEospalax are Qinling and Daba mountains. |
