Molecular clock estimates often date the resolution of genus-level relationships within the Zokor lineage back to which geological period or earlier?
Answer
The Miocene or earlier.
The timeline for the major evolutionary splits within the Zokor lineage, particularly those establishing the relationships between the primary genera such as *Myospalax* and *Eospalax*, has been estimated using molecular clock techniques. These estimations, derived from analyzing the accumulation of genetic differences over time, suggest that the deep divergence leading to these genus-level distinctions occurred significantly in the past. Specifically, molecular clock analyses frequently date these foundational speciation events back to the Miocene geological epoch or periods preceding it, providing the backbone for understanding subsequent dispersal patterns.
