What evidence suggests the genus *Phacochoerus* experienced a long period of independent evolution within Suidae?

Answer

Morphological specialization (warts, molars, grazing) absent in closely related living genera like *Sus*

The evolutionary path of the warthog genus, *Phacochoerus*, appears distinct from other prominent pig genera such as *Sus* (wild boar) and *Potamochoerus* (bushpigs). This divergence is indicated by the high degree of morphological specialization observed in warthogs. Specific features like their prominent facial warts, the unique structure of their molars, and their adaptation towards grazing herbivory suggest they split from the main Suidae family tree significantly earlier than other lineages. The absence of any other closely related living genus sharing these specialized traits points toward a long duration of independent evolution since that initial separation.
