The evolution of partons in the nuclear environment is investigated. It is shown that the evolution of valence and sea (including charm) quarks and gluons is determined by different interaction vertex factors and their effects on their own momentum distributions are also different. By using this parton evolution model, together with the nuclear shadowing effect due to the spatial overlap of partons from neighboring nucleons in the nucleus, the experimental data of the EMC effect and the nuclear Drell-Yan process can be well explained. Therefore, the change of the momentum distribution of partons in the bound nucleon caused by the evolution of partons in the nuclear environment is possibly the origin of the EMC effect. The similarities and differences between the parton evolution model and the Q2-rescaling model are discussed.
