Populations with high genetic diversity have a greater potential for variation, allowing natural selection to act upon them and drive evolutionary change. While continental drift and long-term climatic changes may play a role in the environment of an organism, they do not directly cause genetic diversity or change. Mutation, on the other hand, is a source of genetic diversity but is not necessarily the fundamental cause of evolution, as it is the interaction between genetic variation and the environment (through natural selection) that leads to evolutionary change.
