Why don't zebras fit into the relationship of body size, diet, and social system seen among antelope?
What will be an ideal response?
Zebras are hindgut fermenters, not ruminants like antelope (see Chapter 21). Hindgut fermenters pass large volumes of food rapidly through their digestive systems. They do not face the limitation of rumen volume and the consequent relationship between body size and food quality that is the basis for relationships among body size, diet, and social system seen in antelope.
