What is the primary driver for the evolutionary divergence leading to separate species among geographically separated leopard frog populations?

Answer

Isolation over time allowing populations to evolve independently, leading to reproductive isolation

Geography plays a major role; isolation allows populations to evolve independently, which eventually leads to reproductive isolation and the establishment of new species.
