What is the origin of the African warthog?

The African warthog (Phacochoerus africanus) is native to sub-Saharan Africa, particularly in savannas, grasslands, and woodlands. It is believed to have evolved from a common ancestor shared with other pig species around 20 million years ago. Warthogs are well-adapted to their environment, with physical traits that allow them to thrive in open habitats where they forage for roots, tubers, and grasses. Their distinctive tusks and facial warts serve both as protection and social signaling within their species.
