What physical characteristic reflects the White Rhino's specialization as a grazer, contrasting with ancestral browsers?
Answer
The development of a broad, square lip
The defining morphological trait linked to the white rhino's evolutionary specialization toward grazing is its lip structure. Ancestral rhinos, adapted for browsing on leaves and branches, evolved into the modern *C. simum* which possesses a broad, square lip. This shape functions much like a grazing implement, allowing the animal to efficiently crop large amounts of low-growing grasses close to the ground. This adaptation is directly correlated with the expansion of open grassland ecosystems during geological time scales, enabling the species to capitalize on this specific food source.
