What defines the structure of a vole's molars compared to those of common mice?
Answer
High-crowned with angular cusps
Vole teeth are specifically evolved for a diet consisting of tough vegetation, necessitating high-crowned molars equipped with angular cusps. These structures allow for the effective grinding of fibrous plant material. This dental morphology contrasts sharply with common mice, which possess low-crowned molars with rounded cusps, highlighting the evolutionary divergence between these rodent types based on dietary needs.
